Specifically, the invention adopts four ultrasonic sensors to detect the distances from detection points perpendicular to the same straight line of the fingers to the four fingers, and judges the length sequence of the fingers according to the lengths of the distances from the four detection points to the fingers. The distance is measured by adopting the principle of distance measurement of the ultrasonic sensor, the distance measured by the detection point corresponding to the longest finger is the smallest, and otherwise, the distance measured by the detection point corresponding to the shortest finger is the largest. The left hand and the right hand can be judged only by obtaining two distances with the maximum distance and the minimum distance and the positions of the corresponding detection points. The specific left-hand and right-hand judgment method is as follows: when the palm of the hand is placed upwards, the length of the third finger from left to right is the longest, and the hand is the right hand; when the palm is placed with the second finger from left to right the longest, the hand is the left hand.
The invention can quickly distinguish the left hand from the right hand, automatically detect and reduce misoperation, has no radiation to human body and strong anti-interference capability, and the detection result covers all finger templates, thereby greatly reducing the fault-tolerant rate.
