A user-centric method and system to identify user-made gestures to control a remote device images the user using a three-dimensional image system, and defines at least one user-centric three-dimensional detection zone dynamically sized appropriately for the user, who is free to move about. Images made within the detection zone are compared to a library of stored gestures, and the thus identified gesture is mapped to an appropriate control command signal coupleable to the remote device. The method and system also provides of a first user to hand off control of the remote device to a second user.
