Abstract: Techniques for enhancing the use of a motion capture system are provided. A motion capture system tracks movement and audio inputs from a person in a physical space, and provides the inputs to an application, which displays a virtual space on a display. Bodily movements can be used to define traits of an avatar in the virtual space. The person can be directed to perform the movements by a coaching avatar, or visual or audio cues in the virtual space. The application can respond to the detected movements and voice commands or voice volume of the person to define avatar traits and initiate pre-scripted audio-visual events in the virtual space to provide an entertaining experience. A performance in the virtual space can be captured and played back with automatic modifications, such as alterations to the avatar's voice or appearance, or modifications made by another person.

Abstract: Technology is described for providing realistic occlusion between a virtual object displayed by a head mounted, augmented reality display system and a real object visible to the user's eyes through the display. A spatial occlusion in a user field of view of the display is typically a three dimensional occlusion determined based on a three dimensional space mapping of real and virtual objects. An occlusion interface between a real object and a virtual object can be modeled at a level of detail determined based on criteria such as distance within the field of view, display size or position with respect to a point of gaze. Technology is also described for providing three dimensional audio occlusion based on an occlusion between a real object and a virtual object in the user environment.

Abstract: A computing system runs an application (e.g., video game) that interacts with one or more actively engaged users. One or more physical properties of a group are sensed. The group may include the one or more actively engaged users and/or one or more entities not actively engaged with the application. The computing system will determine that the group (or the one or more entities not actively engaged with the application) have performed a predetermined action. A runtime condition of the application is changed in response to determining that the group (or the one or more entities not actively engaged with the computer based application) have performed the predetermined action. Examples of changing a runtime condition include moving an object, changing a score or changing an environmental condition of a video game.

Abstract: Techniques for managing virtual ports are disclosed herein. Each such virtual port may have different associated features such as, for example, privileges, rights or options. When one or more users are in a capture scene of a gesture based system, the system may associate virtual ports with the users and maintain the virtual ports. Also provided are techniques for disassociating virtual ports with users or swapping virtual ports between two or more users.

Abstract: Systems, methods and computer readable media are disclosed for a gesture recognizer system architecture. A recognizer engine is provided, which receives user motion data and provides that data to a plurality of filters. A filter corresponds to a gesture, that may then be tuned by an application receiving information from the gesture recognizer so that the specific parameters of the gesture—such as an arm acceleration for a throwing gesture—may be set on a per-application level, or multiple times within a single application. Each filter may output to an application using it a confidence level that the corresponding gesture occurred, as well as further details about the user motion data.

Abstract: An on-screen shopping application which reacts to a human target user's motions to provide a shopping experience to the user is provided. A tracking system captures user motions and executes a shopping application allowing a user to manipulate an on-screen representation the user. The on-screen representation has a likeness of the user or another individual and movements of the user in the on-screen interface allows the user to interact with virtual articles that represent real-world articles. User movements which are recognized as article manipulation or transaction control gestures are translated into commands for the shopping application.

Abstract: A camera that can sense motion of a user is connected to a computing system (e.g., video game apparatus or other type of computer). The computing system determines an action corresponding to the sensed motion of the user and determines a magnitude of the sensed motion of the user. The computing system creates and displays an animation of an object (e.g., an avatar in a video game) performing the action in a manner that is amplified in comparison to the sensed motion by a factor that is proportional to the determined magnitude. The computing system also creates and outputs audio/visual feedback in proportion to a magnitude of the sensed motion of the user.

Abstract: In a motion capture system, a unitary input is provided to an application based on detected movement and/or location of a group of people. Audio information from the group can also be used as an input. The application can provide real-time feedback to the person or group via a display and audio output. The group can control the movement of an avatar in a virtual space based on the movement of each person in the group, such as in a steering or balancing game. To avoid a discontinuous or confusing output by the application, missing data can be generated for a person who is occluded or partially out of the field of view. A wait time can be set for activating a new person and deactivating a currently-active person. The wait time can be adaptive based on a first detected position or a last detected position of the person.

Abstract: Techniques for facilitating interaction with an application in a motion capture system allow a person to easily begin interacting without manual setup. A depth camera system tracks a person in physical space and evaluates the person's intent to engage with the application. Factors such as location, stance, movement and voice data can be evaluated. Absolute location in a field of view of the depth camera, and location relative to another person, can be evaluated. Stance can include facing a depth camera, indicating a willingness to interact. Movements can include moving toward or away from a central area in the physical space, walking through the field of view, and movements which occur while standing generally in one location, such as moving one's arms around, gesturing, or shifting weight from one foot to another. Voice data can include volume as well as words which are detected by speech recognition.

Abstract: Disclosed herein are systems and methods for decorating a display environment. In one embodiment, a user may decorate a display environment by making one or more gestures, using voice commands, using a suitable interface device, and/or combinations thereof. A voice command can be detected for user selection of an artistic feature, such as, for example, a color, a texture, an object, and a visual effect for decorating in a display environment. The user can also gesture for selecting a portion of the display environment for decoration. Next, the selected portion of the display environment can be altered based on the selected artistic feature. The user's motions can be reflected in the display environment by an avatar. In addition, a virtual canvas or three-dimensional object can be displayed in the display environment for decoration by the user.

Abstract: Disclosed herein are systems and methods for altering a view perspective within a display environment. For example, gesture data corresponding to a plurality of inputs may be stored. The input may be input into a game or application implemented by a computing device. Images of a user of the game or application may be captured. For example, a suitable capture device may capture several images of the user over a period of time. The images may be analyzed and processed for detecting a user's gesture. Aspects of the user's gesture may be compared to the stored gesture data for determining an intended gesture input for the user. The comparison may be part of an analysis for determining inputs corresponding to the gesture data, where one or more of the inputs are input into the game or application and cause a view perspective within the display environment to be altered.

Abstract: Systems, methods and computer readable media are disclosed for manipulating virtual objects. A user may utilize a controller, such as his hand, in physical space to associate with a cursor in a virtual environment. As the user manipulates the controller in physical space, this is captured by a depth camera. The image data from the depth camera is parsed to determine how the controller is manipulated, and a corresponding manipulation of the cursor is performed in virtual space. Where the cursor interacts with a virtual object in the virtual space, that virtual object is manipulated by the cursor.
