moMo : A Haptic Navigational Device




Momo is a haptic navigational device that requires only the sense of touch to guide a user. No maps, no text, no arrows, no lights. It sits on the palm of one’s hand and leans, vibrates and gravitates towards a preset location. Akin to someone pointing you in the right direction, there is no need to find your map, you simply follow as the device gravitates to your destination.


momo version 4 now has a sturdier lighter frame. A couple switches were added to control power to arduino and to the GPS unit. The whole unit somehow runs off 4 AA batteries instead of 8. I also realized the compass unit is not as accurate as we’d like. It has a sour spot around 180-270 degrees where the measurements are noticably off by several degrees, due to electromagnetic interference from the nearby motors.
