Touch & Go is a navigation system for the blind folks to make them autonomous in the “outside world”. A combo of a hand gadget with earpiece, the system is a wearable navigator with a tactile display that shows the directions as a relief map. The scale used is 1:1000 and plum in the center of it is the user’s position. An arrow indicates the direction the user has to move in and auditory support is provided via the earphone (fitted with an ultrasonic transmitter-receiver). The main device fastens to the back of the hand, it’s quite convenient to carry it around.
