    Abstract: Embodiments described herein use depth images to extract user behavior, wherein each depth image specifies that a plurality of pixels correspond to a user. In certain embodiments, information indicative of an angle and/or curvature of a user's body is extracted from a depth image. This can be accomplished by fitting a curve to a portion of a plurality of pixels (of the depth image) that correspond to the user, and determining the information indicative of the angle and/or curvature of the user's body based on the fitted curve. An application is then updated based on the information indicative of the angle and/or curvature of the user's body. In certain embodiments, one or more average extremity positions of a user, which can also be referred to as average positions of extremity blobs, are extracted from a depth image. An application is then updated based on the average positions of extremity blobs.

    Abstract: Embodiments described herein can be used to detect holes in a subset of pixels of a depth image that has been specified as corresponding to a user, and to fill such detected holes. Additionally, embodiments described herein can be used to produce a low resolution version of a subset of pixels that has been specified as corresponding to a user, so that when an image including a representation of the user is displayed, the image respects the shape of the user, yet is not a mirror image of the user. Further, embodiments described herein can be used to identify pixels, of a subset of pixels specified as corresponding to the user, that likely correspond to a floor supporting the user. This enables the removal of the pixels, identified as likely corresponding to the floor, from the subset of pixels specified as corresponding to the user.

    Abstract: The technology described herein splits the control focus of a user interface during a sustained user interaction. A sustained user interaction is an interaction action lasting more than a threshold period of time. The sustained interaction is initiated when the user directs the control focus of an interface onto an interface object and begins an interaction with the object. Upon determining that a sustained interaction has begun, a control focus lock is executed at the point of control focus where the sustained interaction began, for example, the point where the cursor was located when the sustained interaction began. Upon termination of the sustained interaction, the primary control focus is snapped to the location of the secondary control focus and a secondary control focus is terminated until a subsequent sustained interaction is detected.
