Fuzzy inference system for analog joystick emulation with an inductive tongue-computer interface

Abstract

This paper describes the development of a fuzzy inference system (FIS) for emulating an analog joystick using an inductive tongue-computer interface. The principle of operation of the interface and the inductive sensors signals are described. The FIS receives sensor signals and output the Cartesian position of the virtual joystick, which can be used to control the mouse pointer in a personal computer, wheelchairs or other joystick enabled applications at varying magnitude and directions proportional to the tongue position over the palatal plate. This provides a significant advantage to individuals with tetraplegia using this computer interface. © 2011 Springer-Verlag.
