TOUCHLESS HAND GESTURE DEVICE CONTROLLER
First Claim
1. A touchless operator interface which interprets hand gestures and the movements of these gestures to control electrically controllable devices including plumbing fixtures, electrical instruments, operating room equipment, medical devices, lighting controls, radios, sound equipment, equipment for the disabled, elevators, and clean room processing equipment comprising:
- (a) a digital optical video camera sensor means connected to a digital image processor means and(b) a digital image processor means to interpret hand motions, hand configurations, and hand positions from scans of the digital image at various sequential times from which the digital image processor generates signals for controlling connected devices and(c) an output connection means to send the control signals to the controlled devices.

Abstract
A simple user interface for touchless control of electrically operated equipment. Unlike other systems which depend on distance to the sensor or sensor selection this system depends on hand and or finger motions, a hand wave in a certain direction, or a flick of the hand in one area, or holding the hand in one area or pointing with one finger for example. The device is based on optical pattern recognition using a solid state optical matrix sensor with a lens to detect hand motions. This sensor is then connected to a digital image processor, which interprets the patterns of motion and outputs the results as signals to control fixtures, appliances, machinery, or any device controllable through electrical signals.
