A Unique Smart Eye Glass for Visually Impaired People

摘要

In this paper, we present a unique smart glass for visually impaired people to overcome the traveling difficulties. It can detect the obstacle and measure the distance perfectly using the ultrasonic sensor and a microcontroller. After receiving information from the environment, it passes to the blind person through a headphone. The GSM/GPRS SIM900A module is used to collect the information from the internet. A switch is connected to the system which is used for an emergency task like sending SMS, including time, temperature and location to the subject's guardian when visually impaired people fall into any danger. By using the smart glass visually impaired people can walk in an indoor and outdoor environment.
