Abstract
Disclosed herein are techniques for scaling and translating gestures such that the applicable gestures for control may vary depending on the user's distance from a gesture-based system. The techniques for scaling and translation may take the varying distances from which a user interacts with components of the gesture-based system, such as a computing environment or capture device, into consideration with respect to defining and/or recognizing gestures. In an example embodiment, the physical space is divided into virtual zones of interaction, and the system may scale or translate a gesture based on the zones. A set of gesture data may be associated with each virtual zone such that gestures appropriate for controlling aspects of the gesture-based system may vary throughout the physical space.
