Smart Glass and Alert System for Blind people.

Abstract

Blind mobility is one of the biggest problems that people with vision impairment face on a daily basis. The loss of their eyesight severely limits their quality of life and activities. They typically long-term explorers may use stored memories or a blind navigation system to move about. The major goal of the current effort is to provide a strong, dependable, user-friendly, portable, low power, low-cost solution for efficient navigation. There are multiple smart accessories such as smart glasses, smart watches etc available in the market. There is a significant lack of technology to aid the physically challenged. We wanted to build something which is useful for the visually challenged people. So we designed low cost smart glass that can be useful for visually impaired people. As stated in this study (Smart Glasses for Blind People), the intended audience is those who are visually handicapped. This device includes a pair of glasses and an obstacle detection module fitted in it in the center, a processing unit, an output device i.e. a beeping component, and a power supply. The Obstacle detection module and the output device is connected to the processing unit. The power supply is used to supply power to the central processing unit. The obstacle detection module basically consists of a ultrasonic sensor, processing unit consist of a control module and the output unit consists of a buzzer. The control unit controls the ultrasonic sensors and get the information of the obstacle present in front of the man and processes the information and sends the output through the buzzer accordingly. These Ultrasonic Smart Glasses for Blind people is a portable device, easy to use, light weight, user friendly and cheap in price. These glasses could easily guide the blind people and help them avoid obstacles.
