Abstract

A computing system is configured to receive one or more depth images, from the depth camera, of a world space scene including a human target. The computing system translates a world space position of a hand of the human target to a screen space cursor position of the user interface using a virtual desktop transformation. The computing system also dynamically adjusts the virtual desktop transformation based on a history of button press actions executed by the human target.
