Abstract

Camera-based mouse-replacement systems allow people with motor impairments to control the mouse pointer with head movements if they are unable to use their hands. To address the difficulties of accidental clicking and usable simulation of a real computer mouse, we developed Click Control, a tool to augment the functionality of these systems. When a user attempts to click, Click Control displays a form that allows him or her to cancel the click if it was accidental, or send different types of clicks with an easy-to-use gesture interface. Initial studies of a prototype with users with motor impairments showed that Click Control improved their mouse control experiences. © 2011 Authors.
