R&D of the Japanese Input Method using an eye-controlled communication device for users with disabilities and evaluation with NIRS

This paper describes the Japanese Input Method using a portable eye-controlled communication device for users with disabilities such as Cerebral Palsy or ALS (Amyotrophic Lateral Sclerosis). We proposed three Japanese Input Method and implemented them. Our quantitative evaluation, subjective evaluation by questionnaire and physiologic evaluation with NIRS (Near Infra-Red Spectroscopic) show the effectiveness of the “Roman letters” input method and the “modified beeper” input method.
