Gesture recognition system using depth perceptive sensors
First Claim
1. A method enabling user-interaction with an electronic device using at least one gesture made by a movable body part of said user, the method including the following steps:
- (a) using a sensor system, operable absent ambient light, from which three-dimensional coordinate information is obtainable to acquire three-dimensional space positional information for a plurality of discrete regions on said body part relative to said sensor system;
(b) detecting from said three-dimensional positional information acquired at step (a) occurrence of said at least one gesture; and
(c) classifying each said gesture detected at step (b) as at least one input to said electronic device.

Abstract
Acquired three-dimensional positional information is used to identify user created gesture(s), which gesture(s) are classified to determine appropriate input(s) to an associated electronic device or devices. Preferably at at least one instance of a time interval, the posture of a portion of a user is recognized, based at least one factor such as shape, position, orientation, velocity. Posture over each of the instance(s) is recognized as a combined gesture. Because acquired information is three-dimensional, two gestures may occur simultaneously.
