BBC News reports about a prototype shoe that was designed to control TV sets:
The shoe–dubbed Square-eyes–has a unique insole that records the amount of exercise a child does and converts it into television watching time.
One button on the shoe–the brainchild of a student at west London’s Brunel University–records the amount of steps taken by the child over the day.
Another transmits this information to a base station connected to the TV.
It calculates the time earned and once it runs out, the TV automatically switches itself off.
