The guide dog is a revolutionary specimen all by itself. It is trained to be somebody’s eyes (it sounds really impressive when phrased like that) and it’s hard to believe anything could be more valuable.
Now the limits that guide dogs once had can be erased thanks to the Peepo GPS device. This device uses voice command to mark the destination and then guides the dog along the path using particular vibration that correspond to the direction of travel (left = left, right = right). When the dog has reached the destination, the Peepo GPS will vibrate.
In case of emergency or for any other reason, the touch activated ‘return home safely’ function is quite handy.
