A haptic navigational device requires only the sense of touch to guide a user. No maps, no text, no arrows, no lights. HND sits on the palm of oneâ€™s hand and leans, vibrates and gravitates towards a preset location. Imagine an egg sitting on the palm of your hand, obeying its own gravitational force at a distant location. The egg magically tugs and pulls you. No need to look at any maps. Simply follow the tug.
The possible user scenarios that can come out of this device range from treasure hunts to assistive technology for the blind.
Possible methods of creating the sensation of pull or tug:
Weight shifiting via servo motors
