Low-Cost Blind-Aid Stick to Prevent Accidents of Visually Impaired People

Making life easier has long been a goal of technological development. Everyone today, with the exception of some segments of society, is utilizing the advantages of technology due to a fast-paced lifestyle. The visually impaired are one of them, as they must depend on others for transportation and other activities. This paper intends to present one such theoretical framework that uses cutting-edge technology to offer effective and clever electronic assistance to the blind. This study describes an Arduino-powered walking stick for the blind. This tool makes it easier and more comfortable for blind persons to work and notice impediments. For people who are visually challenged, a conventional stick does not effectively identify obstacles. The device uses an ultrasonic sensor to measure the separation between objects and the Blind-Aid Stick. The ultrasonic sensor can be informed of obstacles by hearing the buzzer's sound when they are within hearing distance of the sensor. By alerting the user to any obstructions in his path, it enables unfettered walking. With the aid of the respective sensors' produced infrared and ultrasonic waves, this proposed methodology is employed to identify the obstruction. A shock sensor is employed to detect whether a physical shock or collision has taken place. An alarm SMS with the location is automatically sent to the ambulance unit using GSM and GPS when it is presumed from the impact that an accident has happened. The major goal of this technology is to create a smart Blind-Aid stick that is extremely helpful for visually impaired folks who frequently require assistance from others.
