foot step 

We propose an input interface using Foot-Step which is gestures of foot for information appliances while jogging. When we use information appliances while jogging, an in- put by Foot-Step is briefer way than conventional physical interfaces because of the hands-free capability. We developed a prototype of a Foot-Step system which enables a user to operate a menu selection system which is widely used for information appliances. The system equips 3-axes acceleration sensors on shoes and users operate a menu system by Foot-Step. As Foot-Step makes the operation of a menu sys- tem a part of jogging, we expect selecting menu motivates users to keep
running and uses enjoy jogging more.
