Abstract: A virtual skeleton includes a plurality of joints and provides a machine readable representation of a human target observed with a three-dimensional depth camera. A relative position of a hand joint of the virtual skeleton is translated as a gestured control, and a three-dimensional virtual world is controlled responsive to the gestured control.

Abstract: Systems, methods and computer readable media are disclosed for controlling perspective of a camera-controlled computer. A capture device captures user gestures and sends corresponding data to a recognizer engine. The recognizer engine analyzes the data with a plurality of filters, each filter corresponding to a gesture. Based on the output of those filters, a perspective control is determined, and a display device displays a new perspective corresponding to the perspective control.

Abstract: A system may receive image data and capture motion with respect to a target in a physical space and recognize a gesture from the captured motion. It may be desirable to isolate aspects of captured motion to differentiate random and extraneous motions. For example, a gesture may comprise motion of a user's right arm, and it may be desirable to isolate the motion of the user's right arm and exclude an interpretation of any other motion. Thus, the isolated aspect may be the focus of the received data for gesture recognition. Alternately, the isolated aspects may be an aspect of the captured motion that is removed from consideration when identifying a gesture from the captured motion. For example, gesture filters may be modified to correspond to the user's natural lean to eliminate the effect the lean has on the registry of a motion with a gesture filter.

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: A virtual skeleton includes a plurality of joints and provides a machine readable representation of a human target observed with a three-dimensional depth camera. A relative position of a hand joint of the virtual skeleton is translated as a gestured control, and a three-dimensional virtual world is controlled responsive to the gestured control.

Abstract: In applications that display a representation of a user, it may be reasonable to insert a pre-canned animation rather than animating a user's captured motion. For example, in a tennis swing, the ball toss and take back in a serve could be a pre-canned animation, whereas the actual forward swing may be mapped from the user's gestures. An animation of a user's gestures can be chained together into sequences with pre-canned animations, where animation blending techniques can provide for a smoother transition between the animation types. Techniques for blending animations, that may comprise determining boundaries and transition points between pre-canned animations and animations based on captured motion, may improve animation efficiency. Gesture history, including joint position, velocity, and acceleration, can be used to determine user intent, seed parameters for subsequent animations and game control, and determine the subsequent gestures to initiate.

Abstract: Systems, methods and computer readable media are disclosed for gesture input beyond skeletal. A user's movement or body position is captured by a capture device of a system. Further, non-user-position data is received by the system, such as controller input by the user, an item that the user is wearing, a prop under the control of the user, or a second user's movement or body position. The system incorporates both the user-position data and the non-user-position data to determine one or more inputs the user made to the system.

Abstract: Embodiments that relate to interacting with a physical object in a mixed reality environment via a head-mounted display are disclosed. In one embodiment a mixed reality interaction program identifies an object based on an image from captured by the display. An interaction context for the object is determined based on an aspect of the mixed reality environment. A profile for the physical object is queried to determine interaction modes for the object. A selected interaction mode is programmatically selected based on the interaction context. A user input directed at the object is received via the display and interpreted to correspond to a virtual action based on the selected interaction mode. The virtual action is executed with respect to a virtual object associated with the physical object to modify an appearance of the virtual object. The modified virtual object is then displayed via the display.

Abstract: Embodiments related to improving a color-resolving ability of a user of a see-thru display device are disclosed. For example, one disclosed embodiment includes, on a see-thru display device, constructing and displaying virtual imagery to superpose onto real imagery sighted by the user through the see-thru display device. The virtual imagery is configured to accentuate a locus of the real imagery of a color poorly distinguishable by the user. Such virtual imagery is then displayed by superposing it onto the real imagery, in registry with the real imagery, in a field of view of the user.

Abstract: Systems, methods and computer readable media are disclosed for gesture shortcuts. A user's movement or body position is captured by a capture device of a system, and is used as input to control the system. For a system-recognized gesture, there may be a full version of the gesture and a shortcut of the gesture. Where the system recognizes that either the full version of the gesture or the shortcut of the gesture has been performed, it sends an indication that the system-recognized gesture was observed to a corresponding application. Where the shortcut comprises a subset of the full version of the gesture, and both the shortcut and the full version of the gesture are recognized as the user performs the full version of the gesture, the system recognizes that only a single performance of the gesture has occurred, and indicates to the application as such.

Abstract: A capture device may capture a user's motion and a display device may display a model that maps to the user's motion, including gestures that are applicable for control. A user may be unfamiliar with a system that maps the user's motions or not know what gestures are applicable for an executing application. A user may not understand or know how to perform gestures that are applicable for the executing application. Providing visual feedback representing instructional gesture data to the user can teach the user how to properly gesture. The visual feedback may be provided in any number of suitable ways. For example, visual feedback may be provided via ghosted images, player avatars, or skeletal representations. The system can process prerecorded or live content for displaying visual feedback representing instructional gesture data. The feedback can portray the deltas between the user's actual position and the ideal gesture position.

Abstract: Synchronous and asynchronous communications between avatars is allowed. For synchronous communications, when multiple users are playing different games of the same game title and when the avatars of the multiple users are at the same location in their respective games they can communicate with one another, thus allowing the users of those avatars to communicate with one another. For asynchronous communications, an avatar of a particular user is left behind at a particular location in a game along with a recorded communication. When other users of other games are at that particular location, the avatar of that particular user is displayed and the recorded communication is presented to the other users.

Abstract: Embodiments for providing instructional information for control devices are disclosed. In one example, a method on a see-through display device comprising a see-through display and an outward-facing image sensor includes acquiring an image of a scene viewable through the see-through display and detecting a control device in the scene. The method also includes retrieving information pertaining to a function of an interactive element of the control device and displaying an image on the see-through display augmenting an appearance of the interactive element of the control device with image data related to the function of the interactive element.

Abstract: Embodiments are disclosed that relate to interacting with a user interface via feedback provided by an avatar. One embodiment provides a method comprising receiving depth data, locating a person in the depth data, and mapping a physical space in front of the person to a screen space of a display device. The method further comprises forming an image of an avatar representing the person, outputting to a display an image of a user interface comprising an interactive user interface control, and outputting to the display device the image of the avatar such that the avatar faces the user interface control. The method further comprises detecting a motion of the person via the depth data, forming an animated representation of the avatar interacting with the user interface control based upon the motion of the person, and outputting the animated representation of the avatar interacting with the control.

Abstract: Embodiments for interacting with an executable virtual object associated with a real object are disclosed. In one example, a method for interacting with an executable virtual object associated with a real object includes receiving sensor input from one or more sensors attached to the portable see-through display device, and obtaining information regarding a location of the user based on the sensor input. The method also includes, if the location includes a real object comprising an associated executable virtual object, then determining an intent of the user to interact with the executable virtual object, and if the intent to interact is determined, then interacting with the executable object.

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.

Abstract: Embodiments are disclosed that relate to authenticating a user of a display device. For example, one disclosed embodiment includes displaying one or more virtual images on the display device, wherein the one or more virtual images include a set of augmented reality features. The method further includes identifying one or more movements of the user via data received from a sensor of the display device, and comparing the identified movements of the user to a predefined set of authentication information for the user that links user authentication to a predefined order of the augmented reality features. If the identified movements indicate that the user selected the augmented reality features in the predefined order, then the user is authenticated, and if the identified movements indicate that the user did not select the augmented reality features in the predefined order, then the user is not authenticated.
