Ultrasonic Sensor Based Haptic Feedback Navigational System for Deaf - Blind People

Abstract

Deaf-Blindness is a rare collective disorder that affects nearly 3.5 million people in today’s world. The improvement restricts the usage of two senses and by large impacts a person’s navigational capability. A variety of aid devices are used to tackle such a disability. But one common drawback that setback them is their inability to address the collective disorder. The proposed project aims at overcoming the aforementioned drawback with the help of ultrasonic sensors and haptic feedback in the form of vibrations. These sensors and feedback mechanisms are to be controlled by a microcontroller in an Arduino. Further, a rechargeable battery shall be used to accommodate the power requirements which emphasizes on energy efficiency. The project commits to limit space constraints by proposing a compact handle design and maximizes its cost efficiency such that it is affordable for everyone equally.
