Serious disabled persons with severe motor disabilities such as amyotrophic lateral sclerosis and progressive speech impairment necessitates the use of an assistive communication aid. Because of the difficulties to move their arms, legs and body, the disabled persons need accessibility equipment to use the communication aids. For those who have residual function in the form of eye movement, our research aims to establish electro-oculo-gram (EOG)-based technology to enable them to operate accessibility equipment. Different eye movement and blinks generate different EOG waveforms, so if a disabled is capable of generating multiple waveforms, the differences could be used as different input keys or switches. Because of the simplicity of application of eye blinks as an input method, in this study we investigated the effectiveness of applying gaze blinks as input keys or switches.
