Device Operation

The BAT Cane performs two functions: keeping the user on a straight path and warning the user of obstacles. Path deviation is detected by an electronic gyroscope mounted in the belt. Obstacles are detected by an ultrasonic sensor mounted on the cane. A small microcontroller interprets the signals from the sensors and warns or corrects the user by activating vibrating motors in the hand (for obstacles) or on the waist (for path deviation).
