Abstract: Techniques for implementing an integrative interactive space are described. In implementations, video cameras that are positioned to capture video at different locations are synchronized such that aspects of the different locations can be used to generate an integrated interactive space. The integrated interactive space can enable users at the different locations to interact, such as via video interaction, audio interaction, and so on. In at least some embodiments, techniques can be implemented to adjust an image of a participant during a video session such that the participant appears to maintain eye contact with other video session participants at other locations. Techniques can also be implemented to provide a virtual shared space that can enable users to interact with the space, and can also enable users to interact with one another and/or objects that are displayed in the virtual shared space.

Abstract: It may be desirable to apply corrective data to aspects of captured image or the user-performed gesture for display of a visual representation that corresponds to the corrective data. The captured motion may be any motion in the physical space that is captured by the capture device, such as a camera. Aspects of a skeletal or mesh model of a person, that is generated based on the image data captured by the capture device, may be modified prior to animation. The modification may be made to the model generated from image data that represents a target or a target's motion, including user gestures, in the physical space. For example, certain joints of a skeletal model may be readjusted or realigned. A model of a target may be modified by applying differential correction, magnetism principles, binary snapping, confining virtual movement to defined spaces, or the like.

Abstract: Optical sensor information captured via one or more optical sensors imaging a scene that includes a human subject is received by a computing device. The optical sensor information is processed by the computing device to model the human subject with a virtual skeleton, and to obtain surface information representing the human subject. The virtual skeleton is transmitted by the computing device to a remote computing device at a higher frame rate than the surface information. Virtual skeleton frames are used by the remote computing device to estimate surface information for frames that have not been transmitted by the computing device.

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. User motion data and/or outputs of filters corresponding to gestures may be analyzed to determine those cases where assistance to the user on performing the gesture is appropriate.

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.

Abstract: A method, medium, and virtual object for providing a virtual representation with an attribute are described. The virtual representation is generated based on a digitization of a real-world object. Properties of the virtual representation, such as colors, shape similarities, volume, surface area, and the like are identified and an amount or degree of exhibition of those properties by the virtual representation is determined. The properties are employed to identify attributes associated with the virtual representation, such as temperature, weight, or sharpness of an edge, among other attributes of the virtual object. A degree of exhibition of the attributes is also determined based on the properties and their degrees of exhibition. Thereby, the virtual representation is provided with one or more attributes that instruct presentation and interactions of the virtual representation in a virtual world.
