       A great new invention by a British student will help children who are overweight. It will also reduce the

number of hours of television they watch every day. The technology is nicknamed "Square-Eyes". It is a tiny,

computerized sensor (感应器) that fits into children's shoes. It measures the number of steps the child takes

during the day and sends the information to the family computer. Software then tells the child how many hours

of TV he or she can watch that evening. One hundred steps equal (等于) one minute of TV. If children use up

all of their viewing time, they must do more walking.

       The designer Gillian Swan says this will help children to include exercise in their daily life from an early age.

Ten years ago children were healthier because they played outside with their friends. But today's children spend

too much time in front of TV and don't exercise. This means children have weight problems and become fat.

"Square-Eyes" is nickname often given to children who watch too much television. It may now have a new

meaning. The new technology is the beginning of computers that become a part of our clothes. What we wear

will soon monitor our health.
