The Design and Implementation of a Vest Made For Visually Handicapped Which Recognizes the Obstacles and Determines the Direction

In this study, the design and implementation of a system was carried out with sensors placed on a vest in order to\ud ensure the visually impaired people to perform their actions without depending on someone else and to improve\ud their quality of life. In this system, 4 pieces of sensors placed on the vest’s front, ground and right-left arms\ud warn the impaired person when less than 150 cm distance remains between the visually impaired and the\ud obstacle. The microprocessor sends signal to the vibration motor which is placed in the direction where the\ud obstacle is situated. With the decrease of the distance the vibration increases so that the person can understand\ud how far and in which direction the obstacle is. For the purpose of not disturbing the other people, instead of\ud audible warning, a new warning system was used with the help of the vibration motors which can be noticed\ud only by the impaired person
