AN ULTRASONIC AID FOR THE BLIND.
Abstract
In an age of rapidly advancing electronics, and subminiaturization, the possibility of providing convenient electronic aids to the physically handicapped is becoming a reality. Devices for the deaf have reached a degree of sophistication not thought possible several years ago. The blind, however, have not reaped the benefits of modern electronics technology to the degree that the deaf have. This thesis describes the work accomplished in designing and testing an ultrasonic aid for the blind. This device provides range and bearing information of nearby objects by means of tactile stimulation, and would provide a useful adjunct to the walking cane.
