Fuzzy model of joystick operation for cursor positioning on a CRT on cervical injuries

Abstract

This report deal with operational characteristics of a pointing device for persons who have cervical injuries and who suffer from spasms and paralysis of extremities. The characteristics are modeled by algorithm of automatic generation for fuzzy inference rule of simplified method. The teaching data of fuzzy inference are obtained on cursor positioning experiments of a joystick with single-speed floating action. It is observed that the fuzzy models exchange the operation rules near by target, and that cervical injury's exchange distances are farther than abled person's exchange distances.<>
