Blindness is a state of lack of visual perception due to physiological or neurological factors. Partial blindness represents lack of integration into the growth of the optic nerve or visual center of the eye, and total blindness is the total absence of visual perception of light. In this work, a simple, cheap and user friendly system is designed and implemented to improve the mobility of blind and visually impaired people in a specific area. The proposed work includes a portable equipment consisting of a lightweight blind stick and a sensor-based obstacle detection circuit is developed to help the blind person navigate safely and avoid any obstacles that may be encountered, either Fixed or mobile, to prevent any possible accident. The main component of this system is the infrared sensor that is used to scan a predetermined area around the blind by emission-reflection waves. The reflected signals received from the barrier objects are used as inputs to the ATMEGA microcontroller. The microcontroller is then used to determine the direction and distance of objects around the blind.
