Abstract: A hand interaction system can use a three-state model to differentiate between normal hand movements, such as reaching for an object, and hand input gestures. The three-state model can specify a sequence of states including: 1) a neutral state, 2) a tracking state, and 3) an active state. In the neutral state, the hand interaction system monitors for a gesture signaling a transition to the tracking state but does not otherwise interpret a gesture corresponding to the active state as input. Once a gesture causes a transition to the intermediate tracking state, the hand interaction system can recognize a further active state transition gesture, allowing active state interaction. Thus, the monitoring for the intermediate tracking state provides a gating mechanism, making it less likely that the hand interaction system will interpret hand movements as input when not so intended by the user.
