CSIRO researchers in Australia had developed Shirt, Pants, Gloves and Socks that can detect the movement of the person who wear the clothes.
The clothes can be used as wireless input devices on computers / musical instrument (air guitar).
Is it possible that in the future gloves/socks/shirts/pants will replace the wireless keyboard/mouse?
