Study of the Character Input with Coding Input Method for Users with Severe Physical Disabilities

Abstract

Serious disabled persons with severe motor disabilities such as amyotrophic lateral sclerosis and progressive speech impairment necessitates the use of an assistive communication aid. However, these disables also need accessibility equipment to use these aids because they have limited control over body movement. Because of the difficulties to move their arms, legs and body, the disabled persons need accessibility equipment to use the communication aids. As they tend to have residual function in the form of eye movement, our research aims to establish eye gaze input technology to enable them to operate accessibility equipment. In this paper we have examined the impact on the accuracy of the direct input time and typographical error rate in input method directly with the coding input method.
