Multifunctional Blind Stick Using Machine Learning – A Review

Abstract

An visually handicapped person finds it tough to find the presence of any obstacles in their approach and it's terribly tough to search out the precise location of the stick if it is misplaced. Thus, the multifunctional blind stick comes as a projected answer to assist the visually impaired folks in their day to day living while not the assistance of others. This paper conducts a survey on few of the vital and up to date developments in blind sticks keep on with the utilization of various microcontrollers, sensors, and technologies. Keywords—ultrasonic sensor, radio frequency transmitter and receiver, obstacle detection, controller, GSM and GPS.
