As soon as they hit the object in front, the waves will return to the glove. Then the waves cause the glove to shake. And the ultrasonic sensor makes different kinds of sounds. The sounds make the user know how far he is from the object. In the college invention competition, the two students got first prize and won 1,540 pounds. One of the designers said, “Now the u |
