A friend of mine has just debuted a shirt with embedded sensors that the wearer controls a guitar with by his movements. Puts the music into air guitar! lol
It's a tech demonstrator for part of a smart materials dev group at the CSIRO labs here in Australia.
He predicts gloves on the market in five years.
