Abstract
The main purpose of the project is to develop a vision system that will enable a person to navigate hallways and around large objects , through the use of an ultrasonic path finder that interfaces with the user via tiny vibrating motors mounted on the user’s hand. The rationale behind this project was to develop a sensory system to enable the blind persons to navigate with the help of GPS, so they can walk around without carrying white cane. We also wanted to use one of the existing senses in helping out people. The report initially gives the main idea about project. Then the development of hypothetical vision substitution for blinds and the research work done on it is documented. Further in report we have explained the problem statement and the logical structure for its solution. The hardware components used in the project are also mentioned along with a description of software approach used. Finally the results of testing and evaluation of our project are explained in detail. We have also discussed the future prospects of the hypothetical vision substitution for blinds. This report also states the research on the effectiveness of the hypothetical vision substitution and different ways of increasing the touch sensation to provide a comfortable and better user experience. It provides the basis for a tactile interface that would be programmable as well, and provides the blinds with many useful applications.
