Accelerometer-based computer mouse for people with special needs

Lluís Ribas Xirgo, Francisco López-Varquiel


A great deal of human-machine interaction depends on hands, and so does access to information technology services. People unable to use hands do require special devices that replace computer mice or touchscreens. In this paper, we present a building kit for a full-featured computer mouse that is controlled by head movements. The resulting kit includes an easy-to-find bill of materials, instructions to build the device and to use it. The experiments conducted with already built devices showed that it works pretty well for most people after a short period of adaptation.
