Hipster beltbuckles have got nothing on this waist contraption from Feelspace. Strap this electronic compass around your waist and one of those circular green sensors vibrates to tell you which direction is north. The creators describe this using more fancy terminology: "vibrotactile stimulation." Not exactly a fashion statement, but the goal of this research is to "investigate the effects of long-term stimulation with orientation information on humans." It also has some obvious short-term uses, say for the blind, people who run marathons across the Sahara desert and tele-sexual fetishists.
