Eye-gaze interfaces using electro-oculography (EOG)
Tohru Yagi · 2010
Using electro-oculography (EOG), two types of eye-gaze interfaces have been developed; "EOG Pointer" and "EOG Switch". The former enables a user to move a computer cursor or to control a machine using only eye-gaze, regardless of drifting signal and blinking artifacts. In contrast, the latter output an ON/OFF signal only. Although it has the least simple function, it enables every user easily to turn ON/OFF a nurse-call device or to send one bit signal to a personal computer with high stability and reliability. Since the EOG Switch was commercialized in 2003, it has been widely used among amyotrophic lateral sclerosis (ALS) patients in Japan.
