Interaction Techniques for Users with Severe Motor-Impairment

Abstract

This chapter presents brief overview of a few new technologies used in interfaces for people with different range of abilities. We discuss about scanning systems that enables one to use a computer or tablet using only one or two switches, eye tracking system that moves a pointer in a screen following eye gaze and finally EEG-based brain computer interfaces. The chapter discusses state of the art on each system, points to a new system by combining more than one modality and finally present existing problems and future vision regarding these technologies.
