A Haptic Navigational Device

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 one’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.

This is what we want to make. (Eduardo Lytton, Kristin O’Friel + me)

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
Vibrations motors
