This device is to be worn on the head and around the hip to aid the visually impaired maneuver around obstacles. It provides information about obstacles near and around the head. When used with a cane, the user will have a complete sense of the topology of surrounding environment. This device decreases the dependence of the visually impaired on others and increases their safety.
The device uses two ultrasonic sensors and a microcontroller to determine the proximity of the user to obstacles. The user has the option to choose between two modes of user feedback-headphones or vibrating motors. Both provide information about the location of and distance to an obstacle. The harder the motors vibrate or the louder the sound is, the closer the user is to an obstacle.
