As graphical user interfaces (GUI) are widely used for human-computer interaction, keyboards as well as pointing devices, such as mice, become of importance. These input devices increase physical loads to operators hands and arms in addition to vision, but other human motor systems, such as feet and legs, seldom be used to interact with computers. We studied the feasibility of foot movement to interact with computers, and prototyped foot-operated pointing devices using plane foot movement on floor and foot inclination on pedal. We found the performance of foot-operated pointing devices of plane movement are comparable with those of hand-operated mice, and better than that of foot-operated devices of inclination.
