Wearable technology for visually challenged people commutation using ultrasonic mapping

Abstract

253 Million People live visual impairment Globally according to World Health Organization (WHO).Assistive technologies plays a major role for the improvement in the quality of life for Visually challenged perosns.Visually impairment Blind people can lead their life either by using manual or technological support. Vision is the dominant sense that assist in execution of day to day activities effectively. The proposed prototype takes care of transition of manual support to technological support with the help of a Wearable device. The Wearable device is being attached with the belt to the top wear of the person and Ultrasonic mapping is used for the commutation of Visually challenged/Blind people without the help of other Human. The Ultrasonic wave is used to detect the obstacle in front and back. It indicates while the obstacle is close enough. If the obstacle is within a reach of 100cm radius, the vibrator connected to it will vibrate and alert the User.
