As shown in Figure 1, Target Recognition, analysis and tracker 10 also can comprise capture device 202.Capture device 202 can be a camera for example; This camera is used in visually to be kept watch on such as one or more users such as users 18; So that can catch, analyze and follow the tracks of the performed posture of one or more users, to carry out one or more controls or the action in using.In example embodiment shown in Figure 1, dummy object is that bowling and user move in three physical dimensions, just looks like the actual bowling of possessing.The bowling 17 that shows on user's the posture may command screen 14 in the physical space.In each example embodiment, can actually hold a physical objects such as user's 18 class targets such as people such as grade.In these embodiment,, make the motion that to use player and object adjust and/or control the parameter of recreation based on the hand-holdable object of user of the system of posture.For example, can follow the tracks of and utilize the player's of hand-held racket motion to control racket on the screen in the electronics physical game.In another example embodiment, can follow the tracks of and utilize the motion of the hand-held object of player to control weapon on the screen in the electronics FTG.

According to an embodiment, Target Recognition, analysis and tracker 10 can be connected to can be to the audio-visual equipment 16 that recreation or application vision and/or audio frequency are provided such as users such as users 18, like televisor, monitor, HDTV (HDTV) etc.For example, computing environment 212 can comprise that these adapters can provide the audio visual signal that is associated with games application, non-games application etc. such as video adapters such as graphics cards and/or such as audio frequency adapters such as sound cards.Audio-visual equipment 16 can be exported the recreation that is associated with this audio visual signal or use vision and/or audio frequency from computing environment 212 receiving said audiovisual signals then to user 18.According to an embodiment, audio-visual equipment 16 can be via for example, and S-vision cable, concentric cable, HDMI cable, DVI cable, VGA cable etc. are connected to computing environment 212.

As as used herein, computing environment can refer to single computing equipment or computing system.Computing environment can comprise non-computation module.As as used herein, computing system, computing equipment, computing environment, computing machine, processor or other computation modules can be exchanged ground and used.For example, computing environment can comprise whole Target Recognition shown in Figure 1, analysis and tracker 10.Computing environment can comprise audio-visual equipment 16 and/or capture device 202.Exemplary audio-visual equipment 16 or any in the capture device 202 or both can be independent but be coupled to the entity of computing environment, perhaps can be the parts of the computing equipment that for example processs and displays.Thus, computing environment can be the independent capture device that comprises the processor that can handle the data that capture.Thus, capture device 202 can be equipped to the data that not only processing captures, and analyzes and the storage data, and data are outputed to screen, or the like.

As shown in Figure 1, Target Recognition, analysis and tracker 10 can be used for discerning, analyzing and/or follow the tracks of the people's class targets such as user 18.For example, can use capture device 202 to follow the tracks of user 18, make can user 18 posture be interpreted as the control that can be used for influencing the application of carrying out by computer environment 212.Thereby according to an embodiment, user's 18 removable his or her healths are controlled application.System 10 can follow the tracks of the motion that user's health and user's health is done, and comprises the posture of control such as the each side of systems such as application, operating system.

System 10 can change into animation with the input to capture device 202, and this input expression user's motion makes this animation imported by this and drives.Thereby user's motion can be mapped to such as visual representations such as incarnation, makes that the user movement in the physical space is simulated by this incarnation.The speed of seizure and display image data frame can be confirmed the continuity level of the motion that is shown of visual representation.

That Fig. 1 has described on computing environment 212 to carry out, can be the example embodiment of the application of the bowling that possibly play of user 18.In this example, computing environment 212 can use audio-visual equipment 16 to come to provide to user 18 visual representation of bowling alley and bowling lanes.Computing environment 212 also can use audio-visual equipment 16 to provide the user 18 can be through his or the visual representation of his moves player's incarnation 19 of controlling.The posture that the computer environment 212 of Target Recognition, analysis and tracker 10 and capture device 202 can be used for discerning and analysis user 18 is made in its three physical dimensions makes this user's posture can be interpreted as the control to the player's incarnation 19 in the gamespace.For example, as shown in Figure 1, user 18 can make the motion of playing bowling in physical space makes player's incarnation 19 in gamespace, make the motion of playing bowling.Other of user 18 move also can be interpreted as control or action, for example to walking, the control selecting ball, incarnation is positioned on the bowling lanes, trundles etc.

A plurality of users can be mutual each other from remote location.Computing environment 212 can use audio-visual equipment 16 to provide another user can use the his or her visual representation that moves player's incarnation of controlling.For example, another kegler's on the audio-visual equipment 16 visual representation can be represented another user, such as in the physical space with this user second user or on-line customer in second physical space together.For a plurality of users of this system of participation, it possibly be useful wearing the immersion display separately or watch through the demonstration of catching real world.For example, the user can check wide environmental area or can focus on interested object or incident in the environment through adjusting individual immersion display.Example immersion display is the wear-type parts (wearable head piece) that comprise capture device and display module.

Posture can be used in such as video-game specific contexts such as bowling example shown in Figure 1.Waiting in another recreation example such as driving recreation, the various motions of hand and pin can be corresponding to operating and controlling vehicle, gearshift, acceleration and brake on a direction.Player's posture can be interpreted as the control corresponding to the action except control incarnation 19, such as the posture that is used for importing at the general-purpose computations context.For example, the various motions of user 18 hand or other body parts can be used for finishing, suspend or preserve recreation, select rank, check high score, exchange with friend etc.

Though Fig. 1 describes the user in the video-game specific context, can conception target identification, the soluble target that is used to control the each side of operating system and/or application outside the recreation scope of analysis and tracker 10 moves.Basically any controlled aspect of operating system and/or application can be controlled through moving of the target such as user 18.For example, user's posture can be corresponding to common system-level task, as in hierarchical lists, navigate up or down, open file, close file and preservation file.User's posture can be to be applicable to the non-aspects of game play of operating system, recreation or the control of non-games application.For example, user's posture can be interpreted as object manipulation, for example controls user interface.For example, consider to have the user interface at blade of homeotropic alignment (blades) from left to right or option cassette interface, wherein will open and use or the option of intrasystem various controls choosing of each blade or tab.This system can identify the hand posture of user's mobile option card, wherein the user's in the physical space hand in fact with the application space in tab align.Comprise that the posture that time-out, extracting motion and hand are then swept can be interpreted into choosing and then it being removed to open next option tab left.

Fig. 2 A and 2B show the example embodiment based on the system 200 of posture that can catch a user shown in the physical space 201 or a plurality of users.System 200 can be from corresponding to discerning posture the data that capture to the control of system 200.The user can use posture to come the demonstration of management information, and perhaps a plurality of users can come to work together so that cooperate with the information of being demonstrated via posture.

System 200 can comprise any amount of computing environment, capture device, display or its combination in any.System 200 shown in Fig. 2 A comprises capture device 202, computing environment 212 and display device 222.System 200 expression shown in Fig. 2 B has the system 200 based on posture of a plurality of computing environment 212,213,214, capture device 202,203,204 and display 222,223,224.Computing environment can be multimedia console, personal computer (PC), games system or control desk, hand-held computing equipment, PDA, mobile phone, cloud computing machine etc., and can comprise or be otherwise connected to capture device or display.Capture device, computing equipment and display device can comprise any suitable device of carrying out required function, such as above-mentioned Fig. 1 of reference or the described equipment of following Fig. 3-8.

Fig. 2 A and 2B both have described to relate to the example such as a plurality of users' such as user 260,261,262,263 the yield-power scene that is used for computer management in the physical space.For example, physical space can be a meeting room, and user 260,261,262,263 possibly participate in a conference or coordinates suggestion.Also can conceive the long-distance user can be from such as second positions such as another room along the hall, perhaps from mutual such as the user's who is positioned at another state family or office etc. even farther remote location and system 200.The Fig. 3 that below describes has described to allow local and the long-distance user both carries out mutual so that carry out the example of the networked environment of the computer management in this scene via the system based on posture.

Yield-power scene in this context can be the form of any information presentation that can manage based on the system 200 of posture via example system shown in Fig. 2 A and 2B etc.In an exemplary scene, user 260,261,262,263 possibly wherein show the output of demonstration application just in session to display 222.Information presentation can comprise animation, figure, text etc.; And in the work product of word processing form, video and/or audio demonstration, slideshow, database application, media player, chart (for example, process flow diagram, pie chart), chat, forum, community, instant message transrecieving or any other form, demonstrate.

Capture device 202 can be caught each the data of user's postures such as posture among expression such as the user 260,261,262,263.Shown in Fig. 2 A and 2B, the distance of the specific components in user and system 200 or this system can be different, and still has the control to the each side of this system.Posture can be identified as the control to information presentation.The posture may command is based on the each side of the system of posture.The posture may command is presented at anything on the screen, such as adding word to document, roll downwards or page turning in document, cross over row in the electrical form, three-dimensional plot is pivoted or rotates, amplifies or dwindle, or the like.For example, consider that display 222 shows that virtual chalk boards or dry type wipe plate, user's posture can be identified as to screen drawing or write between letter, the lantern slide in slideshow switches, suspends slideshow etc.The user can make posture so that add mark of emphasis to the word document.

But posture can combine voice command or voice command replenish user posture.For example, the user can make posture so that add mark of emphasis to document, says then and is added to word document, after mark of emphasis point subsequently.System can be identified as the combination of the posture of adding mark of emphasis and audio frequency and add mark of emphasis and then mark of emphasis control afterwards write in the word of saying.Because the user can make posture with the control demonstration,, the user has a lot of dirigibilities in the room so walking up and down.

The user is not limited to the use controller or must on computing environment, directly presses the button.Yet the use that can conceive posture can combine with the use to controller/button to adapt to this control of two types.Except the user's posture that comprises body kinematics for example, some postures can be used the information via the controller input.

Property purpose presented for purpose of illustration, the snapshot of the example information demonstration shown in Fig. 2 A comprises the Figure 22 5 that is presented on the screen.Other users 260,262,263 and/or long-distance user's (not shown) presentation information in consideration such as the user rooms such as forward such as user such as grade 261.Posture is replaceable or additional to the demand of controller or the similar demand that management is demonstrated.The one side of the application that can accomplish via mouse or clicker or laser instrument or microphone or other peripherals can be accomplished by posture.The posture may command before possibly require the user to have the arbitrary aspect based on the system of posture of controller.For example, posture can be controlled in the virtual laser device of display light on the screen.The user can make posture with finger, rather than uses laser designator through little bright spots being projected in the interested a certain thing of outstanding demonstration on the display.But moving of the mobile simulated laser indicator of user's finger, and this system can discern posture and on screen, show the luminous point that moves corresponding to finger; In fact do not need controller.Posture also may command different or because the each side of the system that other reasons can't be controlled with controller.For example, the motion of control visual representation is directly can using via posture corresponding to the motion of user in physical space, and the animation of visual representation is not the direct conversion of user's posture when needing controller to import.

Fig. 2 B shows another example embodiment of system 200, this system 200 can catch in the physical space 201 the user and with the visual representation of the data map that captures in the virtual environment.Be similar to Fig. 2 A, system 200 comprises capture device 202, computing environment 212 and display device 222.Yet; In this example; System 200 also comprises the additional calculations environment; Such as another capture device 205 and be associated with user 260,263 respectively and be positioned at computing environment closely 213,214 from user 260,263, and the

capture device

203 and 204 that is associated with computing environment 213,214 respectively.

Can carry out message exchange each other via network based on various device in the system of posture or assembly, and communicate to share information.For example, capture device 202,203,204,205 and each computing environment 212,213,214 can communicate through wired or wireless connection, such as connecting or family wireless network via cable connection, Wi-Fi.Each capture device 202,203,204,205 can be shared the data that capture each other, perhaps central computing environment can aggregate data so that handle and decryption.For example, computing environment 212 can be storage and carry out the computing environment to the visible demonstration application of a plurality of users in the physical space 260,261,262,263.Computing environment 212 can receive the data that capture by other assemblies from system, such as directly receiving data from for example capture device 204 or from for example computing environment 214.

Display 222 can be the basic display unit anterior in the room, even be selected to not being all users in the room, also is to the visible size of most of users.This display can be such as head mounted displays such as immersion equipment.For example, head mounted display can be replaced user's the visual field with artificial visual environment.In another example, the only part in the user visual field is replaced by artificial environment.For example, head mounted display can carry out head tracking in case in the display frame in the user visual field overlapped information.This display can be depending on the direction of user's head aligning and adjusts institute's images displayed.For example, if the user just consults a map on display, then each user's head mounted display can comprise that all the expression user checks amplifier section where.Perhaps, the user can navigate in demonstration through other users ground that is different from alternately in the room with his or her individual display.Thus, the authenticity of virtual environment can make that the environment of simulation is more attractive, wherein the user have with virtual reality truer and personalized alternately.

The computing environment 212 that is attached to basic display unit 222 can be assembled from capture device 202,203,204,205 with the data of computing environment 213,214, to analyze the compilation of the data that in physical space, capture.Posture can be from the data of assembling identification and causing to control based on the one side of the system of posture.Providing example network based on this communication between the assembly in the system of posture to be arranged on below with reference to Fig. 3 describes in more detail.

Shown in Fig. 2 B example reflected, can conceive a plurality of users 260,261,262,263 and can carry out alternately via the system component of networking.This system makes a plurality of assemblies can make up its input to use posture.Thus, the each side of a plurality of user 260,261,262,263 these systems of may command.For example, a plurality of capture devices that have different abilities that are used to catch touch, the degree of depth, audio frequency, video etc. can be caught about the data from a plurality of users 260,261,262,263 of physical space.Can assemble and handle and capture data to represent the each side of a plurality of user's control system.This make a plurality of users can via posture and come via system mutual each other, thereby strengthen the cooperative nature in the yield-power environment via posture.

With reference to figure 2B, consider user 260,261,262 and 263 just in session and the equipment 205 that is captured catch, wherein user 260 is associated with another capture device 203, and user 263 is associated with another capture device 204.Physical space can be such as large spaces such as large conference rooms, and the user such as user 263 can take one's seat away from capture device 205.Yet the user can be more near the capture device in the physical space 204, and can via such as display 224 or cellular device (not shown) more near, check shared demonstration on the littler screen.Computing environment 212 can be carried out demonstration application and output to a plurality of displays, such as display 222,223 and 224.

Can analyze data that capture from arbitrary capture device so that carry out gesture recognition, and therefore the arbitrary user in the visual field of the capture device of networking can control the demonstration that is presented on the basic display unit 222 via posture.The user can be through making the each side that posture is controlled shared demonstration to second computing environment in the physical space or capture device.For example, the user can be to more making posture on a small scale near user 263 computing environment 214.If other users in the room or block the for example visual field of capture device 205 such as objects such as displays 224, then this small-scale posture possibly can't help this capture device and caught.User 263 posture can be by capture device 204 seizure and by local computing environment 214 processing or for example shared via network and computing environment 212,213.Therefore any computing environment of in same system based on posture, networking can handle the data that capture from any amount of capture device of also in this system based on posture, networking.User 263 posture can be identified as the control to the demonstration of between computing environment, sharing.The each side of first user's who is associated thus, posture may command second computing environment with first capture device/computing environment.

For example, user 260,263 can be mutual with in-plant computing environment 213,214 respectively via posture, and control corresponding can be transformed into other computing environment in the system, such as host computer environment 212 or with other personal computing environments of this systems connection.Other computing environment in this user's the posture may command session and/or the result of posture can be appeared or otherwise indicated at other on everyone display.For example, user 263 can make posture with the close of computing environment 214.User 263 posture can help the demonstration of managing display on basic display unit 222.Closely capture device 204 can be caught the data of expression user's 263 posture, and computing environment 214 can adopt the gesture recognition technology to come from catch data, to identify posture.Each particular aspects of the computing environment 214 that the posture may command is associated with user 263.Posture can change into the control to host computer environment 212.Thus, the user can make posture with respect near field communication devices and/or capture device, and has the same effect of making the posture that kind just as them with respect to the host computer system.

Can be provided for the additional flexibility of control system 200 to the use of additional capture device and/or computing environment.For example, consider that user wherein is sitting in the large conference room at rear portion, room.In some cases, anterior capture device possibly can't capture the user who is sitting in the rear portion, room in the room.For example, between user and capture device, possibly exist the visual field to block, capture device possibly can't be registered this user, and perhaps capture device possibly not have identifying user or identify the for example resolution of user's access level.The user can make posture with second capture device systems connection in the physical space, such as more near user's capture device or the capture device that is associated with user's personal computing environment.Thus, the system based on posture can be integrated into the each side of demonstrating with management in the system with a plurality of users in every way.

In an example embodiment,, can there be the unique user or the main users of management information demonstration such as in the exemplary scene shown in Fig. 2 A and the 2B.Cooperative system allows and encourages to participate in so that the each side of this system of spectators member's may command via the spectators of posture.The data that can catch a plurality of people in the expression physical space such as the combination of the single capture device of the capture device 202 at the top that is attached to display 222 or suspension capture device 205 on the wall or capture device.A plurality of people can make posture to control single application, such as the application of on computing environment 212, carrying out.For example, be that mapping program and each user work to generate itinerary together if use, then each user can with this single map drawing program alternately to amplify, to pan etc.Because a plurality of users can provide the input of the each side of this application of control via posture, so needn't in the room, transmit a plurality of controllers.Other users can add the room and they also can use posture, and needn't find for example extra controller.

This system can assess the data that capture of a plurality of users of expression and posture thereof passively from other purposes outside the control system.For example, user's posture possibly not be to be that the user deliberately carries out for the one side of control system, but still can be identified from the purpose of data aggregation.Thus, can collect and write down posture or about the information of posture.Consider a plurality of users 260,261,262 and 263 in the physical space.This system can propose a problem on display 222, or can transmit this problem via for example speaker system with listening.This problem can be by can pointing out to the user of other user's presentation information such as user's 261 grades.This system can identify the motion that a plurality of users make in response to this problem, comprises those motions corresponding to posture.Can collect this information and offer in real time such as the outputs such as file or display that are stored in the storer.

For example, system's problem that can propose owing to user or system and poll spectators.Problem can be through simply being or denying to answer that perhaps problem can comprise that a plurality of possible answers and each answer all can be corresponding to postures.For example, problem can be " how many people vote through option A ", and " being " answer can be by comprising that the straight posture of upwards raising one's hand of user representes aloft.This system can detect each user who lifts his or her hand and each user who does not raise one's hand from the data that capture.Therefore this system can be based upon the posture of each ID and come the quantity of " being " response is counted.Thus, system can provide instant poll result.

The posture that system identifies during demonstrating can trigger the subsequent action of this system.For example, system can identify shaking hands between two users, and this shakes hands and can be identified as " introduction " posture between two users in the room, wherein should " introduction " posture comprise that two people shook hands.System can identify each user, sign " introduction " posture, and will about each user's contact information record in daily record, aim at being provided for when meeting adjourned each user this day automatically.Thus, through the visit to the assembly list of contact details, the user can have everyone contact details of shaking hands with it about this user.Another example in the session information recorded can be the sign to the user's interest point in the display frame, wherein can trigger through posture this recording of information.For example, in the session, the user can make posture to indicate this user to the specific screens sectional drawing in the demonstration or put interestedly, and system can comprise that the information of sign in the daily record is so that the user can easily find the information that will consult after a while.Posture can comprise less important posture, touches desk or lifts finger such as finger.Thus, under the situation of not interrupting flow of presentation, system can write down about each user's data based on each user's various postures.Addressable then the information log of each user specific to this user.

Other actions can trigger under system identification goes out the situation of posture.For example, except the incident of above-mentioned discussion, consider other common incidents of taking place in the session, such as appointing responsibility to the meeting participant, dial the user who wants the copy of particular document to long-distance user, indication, or the like.The part of meeting can comprise to each user appoints responsibility.System or user can ask or specify the volunteer, and the posture that is used for designated user that identifies can comprise that the demonstrator points to the volunteer or the volunteer lifts his or her hand.System can be with this gesture recognition for accepting action item, and such as in project-based tabulation or electrical form, this user being associated with this action item.In another example; Can to the user propose such as " you want the copy of the document? " Etc. problem; And depend on " being " posture in the room; System can generate Email automatically, comprises the e-mail address that is associated with each user who makes " being " posture, and the Email of attached document is sent to each user.Action can take place in real time, so that the user can perhaps can be placed in the formation action so that system takes action when meeting adjourned still obtaining the access right to document in session.

But the action of the nextport hardware component NextPort in the action triggering system.For example, if the user lifts his or her hand, then first capture device can receive and handle the data that capture and the hand that lifts is identified as the posture of this user expectation of indication and system interaction.This first capture device can offer second capture device so that turn to the user with instruction, so that this user perhaps focuses on this user better in the visual field of second capture device.Another posture can be that the part with the information of being demonstrated is saved in storer or such as the indication of the users' such as local storage in the personal computing devices local storage, this personal computing devices is such as the computing environment that is associated with user 263 214 computing equipments such as grade.User's posture can be the indication of turning on light, reducing screen, open display device etc.

The action that is triggered owing to posture can be write a Chinese character in simplified form the instruction set that form representes such as grand grade and confirms by using.Thus, system will can define owing to the action that given pose is taked in advance, before beginning in meeting.System can have owing to given pose realize any amount of grand; Thereby producing the user can be seamless action; Such as adding information to daily record or the result being provided to the demonstrator; Perhaps these actions can be known to the user, such as having when coming the Email of information requested via user's posture receiving.Grand can or the application with system be packaged in advance, perhaps these grand can be by user definition.

System can also take the action that produces owing to posture by dynamic mode.For example, the user can use the combination and the request of the order of posture and/or statement to receiving the document users interest through Email hand to be lifted aloft, and statement is used for the order to the selected user send Email then.But the combination of system's response command and posture also sends to each user who raises one's hand with subject document through Email.

In another example, the data about the behavior of user in physical space can be collected by system.For example, the demonstrator possibly expect to have the feedback about the validity of his or her demenstration method.For example, during demonstrating, face feature that system can adopt face or health recognition technology to discern to be present in each user in the physical space/move or body posture/move.Face feature/move, body posture/move or its combination can be corresponding to indication user's the particular emotion or the posture of mood.System can provide the concern of information with indication spectators member to the demonstrator, pay attention to or the rank of corelation behaviour.The user can use this information to be identified at the effective demenstration method that uses during the whole demonstration.For example; If systematic collection is to revealing boring or uninterested posture and these data are related to the user shows a large amount of words on display time about a certain proportion of subscriber's meter of user's indication, then this user can to use this information to come a large amount of words of indicated number be not effective for this organizes user.Yet for different spectators, word possibly be suitable, such as when spectators member is assessing the word in the document.In another example, the user can use animation and interactive technology and system can discern excitement or positive user's participation.Thus, the demonstrator can come in demonstration, to demonstrate to customization based on the information that offers the user in real time, perhaps comes preliminary conference based on the data of previous collection.

System can provide dynamic suggestion to the user based on its detection to the spectators behavior relevant with the demonstration situation during demonstrating.For example, during demonstrating, system can identify boring posture and advise that the user skips many Text slides during many Text slides.System can identify when the user walks up and down in the front portion, room rather than be sitting on one side, and the user obtains better spectators and participates in.System can provide this information to the user during demonstrating, perhaps system can keep watch on spectators in time and participate in and generate the report that the result is provided to the user.

Each user participates in, no matter be presentation information, via posture and system interaction, watch demonstration, or only in the visual field of capture device, demonstrate, all can represent by visual representation.Fig. 2 C has described to comprise the system 200 of another example of capture device 292, computing equipment 294 and display device 291 based on posture.For example, capture device 292, computing equipment 294 and display device 291 can comprise any suitable device of carrying out required function separately, such as equipment described herein.

In this example, degree of depth camera 292 is caught the scene in the physical space 293 that has a plurality of users 260,262,263 therein.Degree of depth camera 292 is handled depth information, and/or to such as computing machines such as computing machines 294 depth information being provided.Depth information can be explained the visual representation for explicit user 260,262,263.For example, degree of depth camera 292 or the as directed computing equipment that it is coupled to 294 can be to display 291 outputs.

Visual representation is a computer representation of taking two dimension (2D) or three-dimensional (3D) model form usually.User's in the physical space 293 visual representation can be taked any form, such as animation, role, incarnation etc.For example, visual representation can be an incarnation, the incarnation of representing

user

260 and 263 respectively 295 or 296 shown in Fig. 2 C.Visual representation can be pointer, arrow or other symbols, such as expression user's 262 hand symbol 297.In this example, monkey role 295 expression users 260 and showing are similar to the body posture of the user's 260 that capture device 292 captures body posture.Expression user's 263 incarnation 296 has the 263 similar physical characteristics with the user, and the clothes of capture device even analysis user 263 also is applied to user's visual representation 296.

Visual representation is introduced shared demonstration to be experienced and can add another dimension to experience through giving the identity sense of user in the Virtual Space.User's visual representation can be present on the display; And other user's avatar in the session can be present on other everyone displays; Thereby produce one group of incarnation in the same Virtual Space, even each user maybe be in different physical spaces.Can everyone incarnation in the session be presented on other everyone televisors, the monitor separately, thereby just obtain looking mutual one group of incarnation in virtual environment.Because the user in the session can comprise long-range and local user, so display can present long-range and the visual representation local user, so that all users can identify other participants based on each visual representation on the scene.

Each user can be represented by its oneself customization visual representation, such as the incarnation or the role of customization.User's visual representation can reflect the characteristic like the user who is captured by capture device.For example, capture device can adopt health/face detection and with the data conversion that captures imaging user's visual representation.Thus, the incarnation on the screen can look and look like and also look like in the action the user.Detected user's visual representation can also be taked the replacement form in the physical space 293, such as animation, role, incarnation etc.The user can select from the various inventory models that system or application provide for expression on this user's screen.For example, be used for visually representing that user's inventory model can comprise any role representation, such as personality's expression, a taffy or an elephant.Inventory model can be illusory role (for example, dragon, strange beast) or symbol (for example, pointer or hand symbol).

Visual representation can comprise the combination of user characteristics and animation.For example, user's visual representation can be such as role 295 roles such as monkey such as grade, but dress as the user's that in physical space, captures clothes or have on detected user's in the picture physical space glasses.User's countenance, body posture, said language or any other detectable characteristic can be applied to visual representation.Inventory model can be an application specific, such as being packaged in program, perhaps inventory model can be stride use available or available in system scope.

User's posture can cause the multimedia response corresponding to the control that is associated with this posture.For example, the animation of user's visual representation can be present on the display owing to a posture.Multimedia response can be such as visual representation mobile wait animation, appear at text message on the screen, any or combination in the audio frequency, rest image, video etc.For example, if the user's posture that the system identification of execution text processing application goes out comprises one page posture down, then the control to word processing file can be following one page of translating in the document.The visual representation that is associated with the user who carries out posture can be for example have with physical space in the large-scale cartoon hand like the similar glasses of user's glasses that capture and identify by system based on posture.In response to following one page posture of user, large-scale cartoon hand is removable to be passed screen and looks and grasp one jiao of document, drop-down then to disclose the following one page in the document.Thus, not only other users can know this this posture of user's executed to the animation of the unique visual representation of specific user based on observing, and animation has increased the experience via the ability of posture control system.The user can visual his or her posture the result, and other users can visualization result.The user can confirm more easily that posture is suitably identified and uses by system.

The multimedia response can be a system scope, such as televisor that demonstrates present each other user or the animation on the monitor.When the user made that his or her incarnation is expressed with posture, posture can be presented on the All Clients position simultaneously.Similarly, when the user talked or otherwise produces audio event (for example through voice-enabled chat) or textual event (for example through text chat), audio frequency or text can be presented on the All Clients position simultaneously.

Particular visual is represented and can be associated with the specific user.Thus, each user can have as he or her self incarnation visual representation, that can the animation that be related to the posture that this user carries out be put into practice.When system showed the animation that particular visual representes, user and other users can distinguish with particular visual and represent the user that is associated.Thus, when user's posture and visual representation animate with corresponding to the control that is associated with this posture the time, which visual representation animate to distinguish that it is possible that which user has carried out posture based on.In another example embodiment, user's visual representation can be general or common between the user, and does not have distinguishing characteristics.Thus, learn that from the animation that is shown it is not to be possible all the time that which user expresses possibility corresponding to particular visual.

In an example embodiment, but the information of the user's that system's storage representation is followed the tracks of motion is stored in the motion capture files.System can the user who catch file from special exercise is special-purpose sports applications in incarnation or game role so that incarnation or game role can animate so that to be similar to the mode skimulated motion of user movement.For example, motion capture files can comprise the indication of the mode that the user jumps.When the jump animation was applied to user's visual representation, system can use from the jump of motion capture files so that visual representation is simulated the user's who is captured by system actual motion.In another example embodiment, it is common general motion that the seizure file is included among the user.For example, can be general or be packaged in advance from the jump of motion capture files, so that visual representation is carried out general jump by system applies the time with system.Multimedia response can be a predetermined response, the animation or the audio clips of the storage that realizes such as the identity in response to given pose.

Multimedia response storehouse can comprise the option of representing like the user's posture that is gone out by system identification.For example, multimedia response storehouse can comprise predetermined or record in advance and animation data that be associated with given pose.Perhaps, multimedia response storehouse can be included in the variety of option of realizing when identifying given pose, and can select based on various situation.For example, can select specific animation, because this animation can be applicable to application-specific, specific user, given pose, special exercise, level of skill, or the like.

In an exemplary embodiment, the animation that is applied to incarnation for example can be to be selected from the animation of the animation library of packing in advance, such as the animation that is accompanied by program, application or system.Selected animation can be with systematic learning to the user import corresponding animation.In a further exemplary embodiment, the animation in the storehouse can be by user input and record the animation in the animation vocabulary of incarnation.

Some animations can be applied to user's visual representation, although this user does not carry out a posture.For example, after inferring user's body language, the visual representation that system can confirm to be applied to this user is to reflect the suitable animation of this user's disposition.In another example, can to detect in special time period specific user be idle or do not make posture in system.But the animate user's of system visual representation is to reflect this user's free time.For example, if user's visual representation is the monkey role, then system can use animation, and this animation comprises that this monkey role grasps virtual pillow and shows that near this monkey " ZZZZZ " sleeps to hint this monkey.

In an example embodiment, the multimedia response can comprise the predetermined incarnation animation that shows with the sound combination.For example, when causing the incarnation walking, can play slight footsteps.In another example, when causing incarnation to be run, can play heavy footsteps.In another example, when causing the incarnation sidesway, can play scraping or slip footsteps.In another example, when causing incarnation collision jobbie, can play clash.In another example, when incarnation causes jobbie to fall or bumps against with another object, can play heavy clash.

Animation rank or animation amount can be depending on and for example use current the execution or spectators' consensus data and changing.For example, just can not comprise than be used to the more animation of the demonstration to child of instructing about the security on the playground in the application of demonstrating law documentation during the court's trial.Thus, can exist by system definition and/or by the user and change with various animations and rank corresponding to user preference.

In an example, the demonstration example can be the order slide demonstration that wherein exists with one group of lantern slide of predesigned order demonstration.In another example, application can be by non-sequential system presentation information.For example, demonstration can comprise the compilation of lantern slide, picture, image, text etc., and demonstration can be organized into each chapters and sections.During demonstrating, the demonstrator is scalable or dwindle each lantern slide and the lantern slide chapters and sections in the slideshow.Can not define the predefine order.

The demonstration of the presentation material of this non-order demonstration can be taked many forms.For example, main screen can comprise map or large-scale process flow diagram.The different piece of scalable map of user or process flow diagram, and can on screen, enlarge one or more lantern slides corresponding to this part.The user can move around on map or process flow diagram, and needn't follow any predefine order.Consider to comprise and have the corridor that is presented at the many doors on the screen or the demonstration form in house.The user can jump between Men Hemen progressively back and forth, enters etc.The user can use scalable painting canvas to come presentation slides, and this painting canvas allows the user or jumps to another part from spectators' participant from the part of demonstration, amplifies and dwindles and define each chapters and sections.Spectators member can navigate to the different piece of demonstration via posture, and as stated, visual representation can with various forms of demonstration style interactions.Thus, demonstration can be the content compilation, and does not require the particular presentation order.The user can get into virtual world and via the each side of ability of posture control demonstration in essence via visual representation.Thus, can show that based on the system of posture the assets painting canvas is for discussion, and the user can navigate in this information in real time.Painting canvas can comprise bulk information, and the demonstrator can be depending on the each several part that spectators select painting canvas.Painting canvas or the demonstration information more information that can comprise than demonstrate, but because form flexibly, user and/or demonstrator can select applicable to the information chapters and sections of discussing.

In an example embodiment,, can there be the unique user or the main users of management information demonstration such as in the exemplary scene shown in Fig. 2 A and the 2B.For example, possibly expect that unique user managing demonstration, and not have Interactive control from spectators member.If consider that user 260 just in session or instruct student-Ta or her of a class possibly want control demonstration separately.Thus, unique user can be presided over information presentation and via the ability of posture control information presentation, but other users' in the room posture maybe uncontrollable information presentation.In another example embodiment, the each side that a plurality of users can control system.For example, possibly expect the each side of a plurality of demonstrator's may command system, perhaps possibly expect to give at least one spectators member's control.Thus, the one group of user can share control to demonstration to launch cooperation better via single or a plurality of capture devices.

The user can share the visit of the each side of control demonstration, has limited visit or does not have visit.For example, the user can be a main users for example, Secondary Users or observe the user.Main users is the arbitrary user of option with each side of control system.Main users can have option from control to other users that distribute.For example, main users can be appointed as second user in the room another main users, Secondary Users or observe the user.Observing the user and can be can be with other user interactions but not via the user of ability of posture control system.

Secondary Users can be authorized the option of the each side of control system.Secondary Users can be given interim control, and in a single day this control authorized just can be infinitely lasting, and perhaps this control can continue up to being taken away.For example, main users maybe be just in presentation information, but does not want mutual from spectators at first.Yet when user's demonstration finished, main users can be asked comment and feedback to spectators member.In an example, main users can select the specific user and give this user's temporary visit so as Secondary Users providing when feedback control system.Secondary Users can make posture with the information that shown of control, such as through turning back to prevpage in the word processing file, outstandingly showing chapters and sections or on display, draw virtual lines (for example, circle and arrow).Thus, Secondary Users can easily come and information interaction via posture, and this can provide the more efficient of user feedback and better understand.When accomplishing, the removable Secondary Users of main users can abandon control to the visit or the Secondary Users of control.

Control to system can shifted between the user or between a plurality of users, share.For example, via the transfer of the control of posture or share to provide and supply the easier mode of customer management information, and need not transmit controller or needn't control the each side of demonstration near computing environment.The user can be from their seat via posture and system interaction.A more than user can be a main users, such as the situation that has a plurality of demonstrators.Each demonstrator is the particular aspects of may command demonstration, so that when they possibly coexist, the content of being demonstrated can be special-purpose also can being visited by the specific user.

In another example, main users can be opened right to speak to obtain the feedback from Any user, to Secondary Users the visit to the Any user in the room is provided thus.Main users can promote the visit to information Control via the posture such as any participants such as Any user that participate in.For example, when demonstration finished, main users can be given an order so that this system handles and discern the posture of the Any user in the room and this posture is changed into control to system.In another example, system can discern the request to control, and determines whether to agree this request.For example, the posture of request control can comprise that the user with the straight upwards act of arm aloft.System can discern the posture that spectators member carries out.System can indicate the user to control via the posture request.System can provide the visit to the each side of controlling this system to the user when identifying the posture of request control, perhaps system can wait for up to the main users mandate and give Secondary Users control.

In another example, system can be indicated as the particular moment of wait in demonstration so that to Secondary Users any visit is provided such as being provided with of being provided with via the demonstrator.For example, before other users of permission had control, system can be indicated as and wait for main users request feedback, and this can be indicated by the posture that supplies system identification.Yet meanwhile, system can generate the formation of user's request through each user that sign is made the posture of request control.Then, when main users was ready to the feedback from spectators, system can show that formation asks the order of controlling with the indication user.

System can identify other situation of the posture of making requesting users, demonstrates such as current information.For example, when main users was demonstrated, spectators member can make the posture of request control, to indicate this user expectation to feed back and/or to have a control to system.As stated, system can discern this user's posture and in formation, identify this user, rather than gives this spectators member's control this moment.When the main users request was fed back, system can not only indicate this user's request, and can turn back to the time point that this user in the demonstration makes posture.Thus, system can automatically return to the display frame of user when making posture.

Notice that data can be caught by any capture device of user in its visual field, and with any computing environment of this capture device networking can be to the The data gesture recognition technology that captures.For example, the host computer environment 210 The data gesture recognition that can capture capture device 205.In another example, the computing environment that is associated with the specific user can be discerned posture.For example, user 263 can be with computing environment 214 mutual and capture device 204 can catch the data of expression user's 263 posture.

The posture that is used for system is carried out identical control can change.In above-mentioned example, the user can make the posture of request control through raising one's hand via the full extension arm.Yet the posture that is used to ask to control can be the small-scale posture, such as finger or hands movement.The definable posture is with the interruption in the restriction flow of presentation.Posture can be depending on user's computing environment mutual with it and changes.For example, the user 263 among Fig. 2 B can carry out small-scale alternately with computing environment 214, but and user application or the special-purpose posture of computing environment.The user can have the gesture data of one group of available on for example this user's personal computing environment or cell phone definition.The user can depend on that thus this user's individual preference makes posture with unique mode.

Appointment to user's access level can be authorized via a plurality of useful sources, such as keeper, system itself by another user in the physical space or application, or the like.For example, the data in the physical space can be caught by system.System can identify all four users 260,261,262,263 in the physical space from catch data.System can identify people's class targets simply in physical space, and perhaps system can identify the specific user based on for example health/face detection.System can specify the specific access rank for each user.

System can be separately based on the scene or come the access level of designated user based on the position of user in physical space.For example, but the data that the capture device 202 shown in analysis chart 2A of system and the 2B captures, and sign is human from the data that capture.Detected each user can be appointed as by acquiescence and have the specific access rank in the physical space.For example, only can be become Secondary Users to visit by default setting based on user capture rank on the scene.System can come the access level of identifying user based on the position of user in the room.For example, the one or more users that take one's seat in the specific part in room or for example child can be appointed as by acquiescence and observe the user.Can revise other appointment of user access level.User's appointment can be dynamic, the activity with the reflection user of change.For example, when the user spoke, system can focus on the user who is speaking so that carry out ability of posture control.

Various scenes with a plurality of participants can have different demands separately, and various characteristics described herein thus can be unique to a scene and comprise the characteristics combination of any variation.For example; From first method of exemplary method described herein or be used for identifying such similar approach of the main users of physical space maybe be more suitable for first scene, but be used for selecting second method of main users maybe be more suitable in another scene.Similarly, access level can be depending on any amount of characteristic and changes, such as application, conference type, user type, the type of info of being demonstrated even time in one day or the illumination in the room.

In another example, user's identity that can sign in to system and this user can be associated with the specific access rank.For example, the founder of information presentation can be associated as main users, and during the founder in identifying physical space, system can be appointed as main users with target.Detected other users of system can be given Secondary Users and specify.Spectators' the user that perhaps, will become the demonstration of main users can sign in to system and when login, be given appointment.Perhaps, main users can define access level for the participant of meeting.

User profiles can be indicated this specific user's suitable access level.For example, system can have the database (for example, health or face feature data) of subscriber profile information, and can the user be related to user profiles.System can be based on user profiles or based on identifying the specific user like the physical characteristics that from the data that capture, identifies.For example, system can analyze the data that capture device 202 captures and adopt health/face detection to identify the specific user.If a user user profiles does not exist, then a user profiles can be created by system.User profiles can provide the indication of this user's that will adopt system access level.

User's appointment as main users, Secondary Users or observation user can be permanent appointment.Perhaps, appointment can change or be changed.In addition, can revise the setting/restriction/constraint of each access level.For example, Secondary Users can have the visit of the each side of control system, but can not have the mandate of authorizing control to other users.Yet setting can be modified so that Secondary Users can be to other user's granted.System or application can be provided with access level based on default information, perhaps can define rank specially for a scene.

As stated, the user can carry out a posture to specify another user's access level.Posture is also applicable to the each side of controlling or management information is demonstrated.For example, if demonstration is carried out with the form of text processing application, then the user can make posture so that in document, advance or page back.Posture go for the one side of outstanding display document and/or on screen, amplify aspect this for have user to the visit of the demonstration that shown carry out more near analysis.

Visual representation can be corresponding to the method for sharing the control of system.For example, if the control of system is transferred to next user from a user, then visual representation can remain unchanged, but the user that conversion is associated with it is with the user corresponding to the acquisition control.In another example, each user can have the visual representation that is associated with he or she, as stated.System can indicate which user is current to be possessed of control power through a certain indication relevant with user's visual representation.For example, the user's who is not possessed of control power visual representation can become ash or fade out from display frame.In another example embodiment, have only current visual representation of making the user of posture just to be shown and/or animate.

Appointment to control can be accomplished via posture.For example, main users can be made the option of posture with the each side that gives Secondary Users' control system by ad hoc fashion.Consideration such as main users such as the user among Fig. 2 B 260 are to demonstrating such as one group of users such as users 261,262,263.Main users can use posture to come the management information demonstration, on screen, draws, gives prominence to the chapters and sections of display document such as change display frame, on the object that moves around on the screen, virtual ground, or the like.

System is addressable or otherwise store the profile that needs not be user's special use, but these profiles possibly comprise the information about different-style.For example, the style profile can comprise the pose information that is applicable to demonstration type, demonstrator's type, spectators' type etc.Preference can be set or can comprise that definition is applied to the default information of the posture of each style.The type of the style profile that the user can select to realize for particular presentation.For example, if the demonstrator is to be that a student of class teaches the composer of music, then posture can be magnify, posture significantly.Yet if the demonstrator is the books and reference materials person with restrained posture, the demonstrator can select to comprise the posture of motion on a small scale.Consideration possibly be present in to one group of potential customers demonstrates the sales force of game information and in the difference between the lawyer of jury's presentation information during the court's trial.The sales force possibly hope to demonstrate with the entertainment way that can have interesting intonation.Thus, the style profile that is applicable to this demonstration can be to have the bigger profile of motion significantly, and the style profile can be indicated and should be shown the visual representation with high animation level.Yet in the example of court's trial, the style profile can comprise less posture and minimum animation.

As stated, the remote computation environment can pass through network shared resource, comprises using and via the control to system from the user's in the physical space separately input.Thus, the user away from the physical space 201 shown in Fig. 2 A and the 2B can be through making the one side that posture is come control system 200 in this user's local physical space.Via network, be that local computing environment can be via the shared information of network and other long-range or local computing environment for the long-distance user, thereby make that the long-distance user can be via the one side of other computing environment of ability of posture control and systems connection.Thus, just on remote system, carry out, then can handle and the each side of analysis user posture with the control remote system if for example use.

Be stressed that the block diagram of describing in the Fig. 4 that below describes and Fig. 7 and 8 is exemplary, and be not intended to hint that one specifically realizes.Thus, the processing unit 259 of the processing unit 101 of the processor 195 or 32 of Fig. 4, Fig. 7 and Fig. 8 can be implemented as single processor or a plurality of processor.A plurality of processors can be located distributed or centralizedly.For example, gesture library 192 can be implemented as the software of on the processor 32 of capture device, carrying out, and perhaps it can be implemented as the software of carrying out on the processor 195 in computing environment 212.Conceived the combination in any that is applicable to the processor of carrying out technology disclosed herein.A plurality of processors can be wirelessly, make up via hardwired or with it and communicate by letter.

Gesture library and filter parameter can be the context fine setting of using or using by the posture instrument.Context can be a cultural context, and can be environmental context.Cultural context refers to the user's of using system culture.Different cultural can use similar posture to transmit visibly different implication.For example, hope to inform that to another user the U.S. user of " seeing " or " using his eyes " can be placed on his forefinger on his head end near his eyes.Yet as far as Italian user, this posture can be interpreted as referring to Mafia.

Similarly, among the varying environment of single application, possibly there is different contexts.To relate to first user's shooting game of operating motorcycle is example.As user during, will point and clench fist towards ground and can express the fist posture forward and from the protruding fist of health in walking.When the user was driving in the context, identical motion can be represented " gearshift " posture.

Posture can be grouped in the style bag of complementary posture together, and these complementary postures possibly be employed use with this style.Complementary posture-or as usually together in those postures of use be complementary, or as the change of the parameter of a posture will change in the parameter of another posture be complementary-can be grouped together in the style bag.These bags can be provided for application, and this application can be selected one of them.Use parameter fine-tuning or modification posture or posture filtrator 191 and come to be fit to best the unique aspect of application.When this parameter of fine setting, second complementary parameters (on complementary meaning) of also finely tuning this posture or second makes these parameters keep complementary.The style bag that is used for video-game can comprise such as styles such as first user's shooting, action, driving and physical culture.

The user's that Fig. 5 A has described to generate from capture device 202 example skeleton mapping.In this embodiment; Identify each joint and bone: the top 526 and the bottom 528 of each hand 502, each forearm 504, each elbow 506, each biceps 508, each shoulder 510, each hip 512, each thigh 514, each knee 516, each shank 518, each foot 520,522, trunk 524, vertebra, and waist 530.Following the tracks of under the situation of multiple spot more, can identify additional characteristic, such as the bone and the joint of finger or toe, or each facial characteristic, like nose and eye.

The user can create posture through the health that moves him.Posture comprises user's motion or attitude, and it can be captured as view data and resolve its meaning.Posture can be dynamic, comprises motion, like the imitation pitching.Posture can be a static attitude, intersects like trunk 524 fronts a people and holds his forearm 504.Posture can be single moving (for example, jumping) or continuous posture (for example, driving), and on the duration, can lack and can grow (for example, driving 202 minutes).Posture also can combine stage property, as through brandishing imitated sword.Posture can comprise more than a body part, as clapping both hands 502, or more small motion, as sticked up a people's lip.

User's posture can be used as the input in the general computational context.For example, the various motions of hand 502 or other body parts can be corresponding to common system-level task, as in hierarchical lists, navigate up or down, open file, close file and preservation file.For example, the user can upwards refer to and the centre of the palm makes his hand maintenance motionless to capture device 202 with finger.He can draw finger in then and form fist towards palm, and this can be that indication should pent posture based on the focus window in the user interface computing environment of window.Posture also can depend on to play in the video-game specific context to be used.For example, for driving recreation, the various motions of hand 502 and pin 520 can be corresponding to operating and controlling vehicle, gearshift, acceleration and brake on a direction.Thus, but the posture indication map represent to the user who is shown, such as the various motions in the wide variety of applications such as video-game, text editor, word processing, data management.

The user can walk in the original place or run and generate the posture corresponding to walking or running through oneself.For example, the user can alternatively mention and put down each leg 512-520 and comes to plan to implement away at the situation counterdie that does not move.System can resolve this posture with each thigh 514 through analyzing each hip 512.When a hip-thigh angle (like what measure with respect to perpendicular line, the leg of wherein standing has hip-thigh angle of 0 °, and the leg of horizontal stretching has hip-thigh angle of 90 ° forward) surpasses the specific threshold with respect to another thigh, can discern a step.Walk or run and after the continuous step of a certain quantity that replaces leg, to be identified.Time between two nearest steps can be considered to one-period.Do not satisfying after threshold angle reaches the cycle of a certain quantity, system can confirm that the walking or the posture of running stop.

Given " walk or run " posture is used and can be the pre-set parameter that is associated with this posture.These parameters can comprise that the periodicity that the step does not take place and definite posture of the required step number of above-mentioned threshold angle, initiation walking or the posture of running, recovery are walking or the threshold period of running.Fast period can be corresponding to running, because the user will move his leg apace, and the slower cycle can be corresponding to walking.

Posture can be associated with one group of default parameters at first, uses available its oneself parameter and covers this group default parameters.In this scene, not forcing to use provides parameter, can change the default parameters that uses a group to allow identification posture under the situation of the parameter that does not have application definition into but use.The information relevant with posture can be stored the purpose of the posture animation that is used for prerecording.

The various outputs that existence can be associated with posture.Can exist about posture occurent baseline " be or not " whether.Level of confidence can also be arranged, and it is corresponding to the possibility corresponding to posture that moves of usertracking.This can be that scope is the linear scale of the floating number that (comprises end points) between 0 and 1.Can not accept in the false application as input certainly in the application that receives this pose information, it can only use has high confidence level, the posture of having discerned as at least 0.95.Under the situation of using each instance that must the identification posture, even be cost certainly with vacation, it can use the posture that has much lower level of confidence at least, as only greater than those postures of 0.2.Posture can have two outputs of the time between the step recently, and under the situation of only having registered the first step, this can be set as retention, like-1 (because the time between any two steps just is necessary for).Posture also can have the output about the highest thigh angle that during a nearest step, reaches.

Another exemplary posture is " heel is mentioned jumping ".In this posture, the user can be through lifting from ground with his heel, creates this posture but keep his toe to land.Alternatively, the user can jump in the air, wherein his pin 520 complete built on stilts.Whether this system can resolve the skeleton of this posture through the angular relationship of analyzing shoulder 510, hip 512 and knee 516, are the aligned positions that equal upright to check them.Then, can keep watch on these points with higher 526 and low 528 vertebras point find any upwards acceleration.Enough acceleration combinations can trigger the jump posture.Enough combinations of acceleration and a certain posture can be satisfied the parameter of tr pt.

Given " heel the is mentioned jumping " posture of being somebody's turn to do is used and can be the pre-set parameter that is associated with this posture.Parameter can comprise above-mentioned acceleration rate threshold, and it confirms certain combination of user's shoulder 510, hip 512 and knee 516 must move up how soon trigger this posture; And comprise the maximum alignment angle that still can trigger jump between shoulder 510, hip 512 and the knee 516.Output can comprise level of confidence, and the body angle of user when jumping.

Based on the details of the application that will receive posture come for the posture setup parameter for identifying posture exactly, be important.The intention that correctly identifies posture and user greatly helps to create positive user experience.

Application can identify the point that uses the animation of prerecording for the parameter setting values that is associated with various tr pts.Tr pt can be defined by various parameters, like angle or its any combination of sign, speed, target or the object of given pose.If tr pt is defined by the sign of given pose at least in part, then correctly identify posture and help to improve the confidence level that the parameter of tr pt has been satisfied.

Another parameter for posture can be the distance that moves.Under the situation of the action of the incarnation in user's ability of posture control virtual environment, this incarnation can be the length that arm leaves ball.If the user hopes mutual and catch it with this ball, then this arm 502-510 that can require the user to stretch him makes grip posture simultaneously to total length.In this situation, the similar grip posture that the user only partly stretches his arm 502-510 possibly can't reach the result mutual with ball.Similarly, the parameter of tr pt can be the sign to grip posture, if wherein the user only partly stretches his arm 502-510, thereby does not have to realize and the mutual result of ball that then user's posture will not satisfy the parameter of tr pt.

The space body that posture or its part can must it take place therein is as parameter.Comprise that in posture this space body can be expressed with respect to health usually under the situation that health moves.For example, for the rugby throwing gesture of right-handed user can be only be not less than right shoulder 510a and with the space body of throwing arm 502a-310a in 522 same side in discern.All borders that maybe unnecessary definition space body as for this throwing gesture, are wherein kept from the outside border of health and are not defined, and this space body ad infinitum stretches out, and perhaps extend to the edge of the scene of just being kept watch on.

Fig. 5 B provides the further details of an exemplary embodiment of the gesture recognizers engine 190 of Fig. 4.As shown in the figure, gesture recognizers engine 190 can comprise at least one filtrator 519 that is used for confirming one or more postures.Filtrator 519 comprises the information of definition posture 526 (below be called " posture "), and can comprise at least one parameter 528 or the metadata that for example is used for this posture 526.For example, comprise that a hand crosses preaxial motion behind from health and can be implemented as and comprise that a hand representing the user crosses the posture 526 of preaxial mobile information behind from health, this moves being caught by degree of depth camera.Can set the parameter 528 of this posture 526 then.In posture 526 is under the situation of throwing; Distance that parameter 528 can be this hand threshold velocity that must reach, this hand must be advanced (absolute, or with respect to user's whole size) and the degree of confidence that takes place by the posture 526 that recognizer engine 190 is graded.These parameters 528 of posture 526 can in response to and different, because of the context of single application different or in a context of an application along with the time changes.

Filtrator can be modular or interchangeable.In one embodiment, filtrator has a plurality of inputs and a plurality of output, and each in these inputs all has a type, and each in these outputs all has a type.In this situation, first filtrator can be replaced with second filtrator that has input and output of equal number and type with first filtrator, and needn't change other aspects of recognizer engine 190 architectures.For example, possibly have first filtrator that is used to drive, this first filtrator with skeleton data as input and posture 526 occurent degree of confidence and the steering angles that are associated with this filtrator of output.Drive filtrator in hope with second and replace this and first drive under the situation of filtrator (this possibly be because second to drive filtrator more efficient and need processing resource still less); Can come to do like this through replacing first filtrator with second filtrator simply, as long as second filtrator has same input and output---input of skeleton data type and two outputs of degree of confidence type and angular type.

Filtrator need not have parameter 528.For example, " user height " filtrator that returns user's height possibly not allow any parameter that can be finely tuned.Alternative " user's height " filtrator can have fine-tuning parameter, such as the footwear, hair style, headwear and the figure that when confirming user's height, whether consider the user.

Can comprise such as joint data, as the formed angle of bone that intersects at joint, from the rgb color data of scene and user's contents such as rate of change in a certain respect the input of filtrator about user's joint position.Output from filtrator can comprise such as the degree of confidence of just making given posture, make the speed of posture motion and the contents such as time of making the posture motion.

Gesture recognizers engine 190 can have the basic recognizer engine 517 that function is provided to posture filtrator 519.In one embodiment; The function that recognizer engine 517 is realized comprises: the input in time (input-over-time) of following the tracks of the posture discerned and other inputs is filed, hidden Markov model realize (wherein modeling system be assumed that have unknown parameter Markovian process-wherein current state has encapsulated the required any past state information of definite state in future; Therefore needn't safeguard the process of any other past state information for this purpose, but and hiding parameter confirm from observed data) and other required functions of particular instance of finding the solution gesture recognition.

Basis recognizer engine 517 can comprise posture profile 520.For example, basic recognizer engine 517 can be loaded into posture profile 520 in the gesture recognition engine for the user temporarily, posture profile 520 is stored in the posture filter information, or otherwise from remote location access posture profile 520.It is that information self-adapting in the filtrator 519 is with the parameter corresponding to the specific user that posture profile 520 can provide.For example, as stated, posture 526 can be the throwing with parameter of threshold velocity that hand must advance or distance.Posture profile 520 can define threshold velocity or the distance that hand must be advanced again for throwing gesture 526.Therefore, basic recognizer engine 517 can be used from the parameter of posture profile 520 and replenish or replace the parameter in the filtrator 519.Filtrator 519 can be that acquiescence pose information and posture profile 520 can load for the specific user specially.

Filtrator 519 loads on basic recognizer engine 517 and realizes, and engine capable of using 517 offers the service of all filtrators 519.In one embodiment, the received data of basic recognizer engine 517 processing confirm whether it satisfies the requirement of any filtrator 519.Because these wait the service that provided to provide but not provided by each filtrator 519 by basic recognizer engine 517 is disposable such as resolving input; Therefore this service only need be processed once in a period of time rather than in this time period each filtrator 519 handled once, has reduced the required processing of definite posture thus.

The filtrator 519 that application program can use recognizer engine 190 to be provided, perhaps it can provide its oneself filtrator 519, and this filtrator is inserted in the basic recognizer engine 517.Similarly, the posture profile can be inserted in the basic recognizer engine 517.In one embodiment, all filtrators 519 have the general-purpose interface of launching this insertion characteristic.In addition, therefore all filtrator 519 parameters 528 capable of using can use the single posture instrument that is described below to debug and finely tune whole filter system 519.

These parameters 528 can be regulated for the context of using or use by posture instrument 521.In one embodiment, posture instrument 521 comprises that the figure of a plurality of slide blocks 523 and health 524 representes, each slide block 523 is corresponding to a parameter 528.When adjusting parameter 528 with corresponding slide block 523, health 524 can be showed action that will be identified as the posture with these parameters 528 and the action that will not be identified as the posture with these parameters 528, like what identified.The visual effective means that debugging and fine tuning posture are provided of this of the parameter 528 of posture.
