Abstract

Science and technology has always played a prominent role in comforting human lives. The main objective of this work is based on mollifying the disabilities of blindness by creating a microcontroller based automated hardware that can ratify a visually impaired person to detect obstacles in front of him/her instantly and guide him/her in a proper way to reach his/her destination. The hardware consists of a microcontroller integrated with Arduino Uno board, microcontroller, ultrasonic sensor, GPS module, GSM module, serial driver, buzzer, LED and other additional equipments. It acts as a better navigational tool for the visually impaired. The sensors used in this model provide information about the outside environment. GPS Technology is integrated with pre-programmed locations and it is sent to the desired number through GSM module when required. This presents a design and a system concept to provide smart electronic aid for blind people. The aim of the overall system is to produce an economic and productive navigation aid for the visually challenged which can give them a sense of artificial vision and object detection by providing information about the environmental scenario of static and dynamic objects around them. Ultrasonic sensors are used to detect obstacles from a distance so as to guide the blind perso in the right path.
