Smart Alert and Intimation System for Vip (Visually Impaired Person)

People with visual difficulties often rely on others and supporting technologies. Many aid devices are currently available, including assistive cane, Electronic Travel Aid (ETA), etc. There are several drawbacks to these devices, including high costs. Some use guide dogs that need several years of guidance and are therefore very expensive. Blind people do not find these devices easy and viable. The main aim of this paper is to provide blind people with low-cost, safe intimation devices. This system detects obstacles using ultrasonic sensors to avoid the barriers, and so this system produces a buzzer sound. If the blind person in a susceptible situation, the Global System for Mobile Communication (GSM) has been used to making an instant call, alerts their collective mates. Barriers on the route are detected with an ultrasonic sensor in the head (helmet). The user is indicated by a buzzer sound for the presence of obstacles. This work combined all the above functions and provided blind people with a low-cost portable warning and intimation module.
