Arduino based automated STICK GUIDE for a visually impaired person

摘要

In this paper a stick guide model represented for visually impaired persons to guide in their way, which consist of a Global Positioning System (GPS) and a Global System for Mobile communication (GSM) modules along with sensors like Ultrasonic and Infrared sensors. This is a smart stick that will make the visually impaired persons guiding their way. GPS module is used in this to get the current location information of the person, that location will be sent via Short Message Service (SMS) to the registered numbers using a GSM module, on pressing of a switch whenever he feels he is lost. Ultrasonic sensors are used for obstacle detection through the ultrasonic waves produced by it, and Infrared sensor is used for level detection and both the sensors are interfaced with the vibrator which vibrates on detecting an obstacle. The main objective of this model is to help a blind to live a better life.
