Project HALO is a haptic feedback device that helps the visually impaired navigate freely without the assistance of a cane or guide. Developed by a Instructables user ‘polymythic’, the gadget uses ultrasonic rangefinders that takes input from sensors and outputs the feedback to the vibration motors set up around a person’s head. As the wearer gets closer to a blocking object, the vibration in the device increases indicating him to alter his direction. Conversely, if there’s no vibration, he can safely continue walking in that path.
