Typing with eye-gaze and tooth-clicks

Abstract

In eye-gaze-based human-computer interfaces, the most commonly used mechanism for generating activation commands (i.e., mouse clicks) is dwell time (DT). While DT can be relatively efficient and easy to use, it is also associated with the possibility of generating unintentional activation commands -- an issue that is known as the Midas' touch problem. To address this problem, we proposed to use a "tooth-clicker" (TC) device as a mechanism for generating activation commands independently of the activity of the eyes.
