May 20, 200520 yr http://www.newscientist.com/article.ns?id=dn7395&print=true Sports shoes that work out whether their owner has done enough exercise to warrant time in front of the television have been devised in the UK. The shoes - dubbed Square Eyes - contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day's exertions.
