Smart Blind Stick

People with complete blindness or low vision often have a difficult time self-navigating in outside environments. In fact, physical movement is one of the biggest challenges for blind people, explains World Access for the Blind. Traveling or simply walking down a crowded street may pose great difficulty. Because of this, many people with low vision will bring a sighted friend or family member to help navigate unknown environments. This project is a solution to this navigation issue. It consists of a blind stick which is equipped with ultrasonic sensors and pager motors. The stick scans for obstacles (people) and when found, it points a light in the same direction of the obstacle. Additionally, the pager motor vibrates if there is there is an obstacle that is approaching the blind person at relatively faster speed. This would help a blind person understand where the obstacle is and also its direction.
