Gesture recognition system
First Claim
1. A computer system for recognizing gestures made by a moving subject, comprising:
- a sound detector for detecting sound;
one or more image sensors for capturing an image of the moving subject;
a human recognizer for recognizing a human being from the image captured by said one or more image sensors; and
a gesture recognizer, activated when human voice is identified by said sound detector, for recognizing a gesture of the human being.

Abstract
The present invention provides a system for recognizing gestures made by a moving subject. The system comprises a sound detector for detecting sound, one or more image sensors for capturing an image of the moving subject, a human recognizer for recognizing a human being from the image captured by said one or more image sensors, and a gesture recognizer, activated when human voice is identified by said sound detector, for recognizing a gesture of the human being.
In a preferred embodiment, the system includes a hand recognizer for recognizing a hand of the human being. The gesture recognizer recognizes a gesture of the human being based on movement of the hand identified by the hand recognizer. The system may further include a voice recognizer that recognizes human voice and determines words from human voice input to the sound detector. The gesture recognizer is activated when the voice recognizer recognizes one of a plurality of predetermined keywords such as “hello!”, “bye”, and “move”.
