Abstract: Humans get most of their total information through eyes. Hence eyes contribute to a major part of the human’s life. So with the advancement in the technology of both the hardware and software a low cost smart stick can be made to make the life of the visually impaired people easier and more comfortable. This paper presents a system concept and model to provide a smart electronic aid for blind people. This system is intended to provide the blinds with an aid, so that they can travel or go from one place to other with ease, without the need of an assistant to assist them where ever they go. This system basically aims at making a visually impaired person independent and swifter. Generally, the visually impaired people use a stick to avoid collisions and to locate the obstacles that comes their way. But due to certain limitations these sticks prove to be less efficient and frequent injuries are caused to the blind. To reduce the chances of any such injuries to the blind, this stick can be installed with some electronics equipments that work together to help the blind by making his journey easier, more comfortable and less prone to injuries. This system designed mainly consists of sensors, microcontroller, voice recording IC, speakers, vibration circuitry and a GSM module. All these are fixed to the stick making it a smart stick. Sensors sensing any obstacle alert the blind either via vibration circuitry or via speakers (voice driving unit). Further whenever the blind finds himself in trouble or finds himself lost he can use a panic button and GSM module to convey it to his near and dear ones via a pre stored message indicating his situation. In this way he is just a push away from his family.
