Gesture recognition is one of the most important scenarios in human-machine interface application
and present methods are generally based on surface electro myogram( s EMG) signals. In order to explore new sensing mode
a novel gesture recognition system based on ultrasonic sensor is designed. Sensors are placed on forearm to detect echo information of muscle interface
so as to carry out character exraction and pattern recognition and wrist and finger motions can be recognized. Experimental results show that the system has good recognition effect on fine motion of finger
average recognition rate of five fingers motion is( 91. 1 ± 4. 73) %.
