Abstract

In this research project, tests were conducted to see whether a person could avoid a series of objects without vision, while using a custom made sonar device. This device would eventually be used to assist the blind. For the experimentation, an obstacle course was set up which consisted of objects which one might come across every day. There was a large toy jeep, two foldable chairs, a row of balls, two bicycles, a low lying ridable toy, two large lawn chairs, and a large gate. The test subjects were asked to navigate through the obstacle course while detecting, and avoiding, as many objects as possible. The results showed that the test subjects were able to complete the obstacle course while detecting and avoiding every single object 23 of the 40 trials. The most missed object was the low lying ridable toy which was about 8 inches of the ground. Overall, the device seemed to be capable of detecting a variety of different objects. It was also able to help the test subjects navigate throughout the obstacle course well. Even though there were only 23 perfect runs, out of the 280 combined opportunities there were for the test subjects to detect any of the 7 different objects, only 23 objects were missed.
