title = "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. This paper describes a pilot study that verifies the feasibility of using an eye-gaze tracker (EGT) and a TC to type on an on-screen keyboard, and compares the performance of the EGT-TC system with that of the EGT with two different DT thresholds (880 ms and 490 ms). The six subjects that participated in the study were able to attain typing speeds using the EGT-TC system that were slower than but comparable to the typing speeds that they attained using the EGT with the shorter DT threshold.",
