Blind Walking Stick

Abstract

Blind people consists of a large group of people in our society. Losing their eyesight has caused them inconvenience in performing daily tasks. Hence, smart cane had been developed in order to increase the life quality of a blind person. The purpose of this project is to design a smart cane with an ultrasonic sensor and global positioning system for the blind. This embedded system mainly has two parts, mobility, and navigation system. For mobility system, it is equipped with ultrasonic sensor HCSR04, soil moisture sensor, LDR, buzzer and vibrating motor. Ultrasonic sensor will send the trigger pulse to detect obstacles. When an obstacle is detected, signals will be sent to vibrating motor and buzzer to activate them. For navigation system, the SKM53 global positioning system is used to get real-time coordinates. The prototype of the smart cane was built to increase the mobility of the blind people and with the navigation system
