Third Eye for Blinds

Abstract

An innovative product which includes aspects of hardware product design, software engineering, and health science is the third sight for the blind. For the physically challenged especially those affected by blindness, the device provides an easier way of navigating through the roads by using ultrasonic waves to identify forged adjacent obstacles and alerts the user with sound or vibration. Global blindness is estimated at 39 million people, and therefore universally recognized aids such as the white stick are practically useless. The wearable technology proposed here is developed based on the fairly inexpensive Arduino NANO board with the ultrasonic sensors which have GPS module in them. This is made easy through a warning system that the device produces when its sensors detect barriers to movements. Taking all this into consideration, I assume that the blind would gain much from this automated equipment, and would be able to get around much more easily.
