Abstract: A method for estimating a metabolic equivalent of task for use with a computing device is provided herein. The method includes receiving input from a capture device of a user; and tracking a position of each of the plurality of joints of the user. The method further includes determining a distance traveled for each of the plurality of joints between a first frame and a second frame; and calculating a horizontal velocity and a vertical velocity for each of the plurality of joints based on the distance traveled and an elapsed time between the first and second frames. The method further includes estimating a value for the metabolic equivalent of task using a metabolic equation including a component for the horizontal velocity and a component for the vertical velocity for each of the plurality of joints; and outputting the value for display.

Abstract: Embodiments are disclosed that relate to push and/or pull user interface elements in a user interface with which a user interacts via a depth camera. One embodiment provides a computing device configured to display an image of a user interface comprising one or more interactive user interface elements, receive from a depth camera one or more depth images of a scene including a human target, and display a rendering of a portion of the human target as a cursor positioned within the user interface and also provide to the display a rendering of a shadow of the cursor cast on one or more of the interactive user interface elements. The computing device is further configured to translate movement of the human target hand to the cursor such that movement of the human target hand causes corresponding actuation of a selected interactive user interface element via the cursor.
