Abstract
Gesture modifiers are provided for modifying and enhancing the control of a user-interface such as that provided by an operating system or application of a general computing system or multimedia console. Symbolic gesture movements are performed by a user in mid-air. A capture device generates depth images and a three-dimensional representation of a capture area including a human target. The human target is tracked using skeletal mapping to capture the mid-air motion of the user. Skeletal mapping data is used to identify movements corresponding to pre-defined gestures using gesture filters. Detection of a viable gesture can trigger one or more user-interface actions or controls. Gesture modifiers are provided to modify the user-interface action triggered by detection of a gesture and/or to aid in the identification of gestures.
