A Multiple-choice Input Interface using Slanting Eye Glance

Abstract

The eye gaze input is attracting attention as a method for operating an information device with hands-free. However, it is difficult to use gaze input system over a small screen such as a smart device because eye gaze input method must accurately measure gaze positions. In order to solve this problem, we have proposed the eye-glance input method to use operating a small information device like smart phone. The eye-glance input method is able to input multiple-choice using oblique direction reciprocating movement. Accordingly, enabling an input operation that is independent of the screen size. In this paper, we report result of evaluation experiment of numbers inputting of using our developed a Multiple-choice eye-glance input system that utilized electrooculography that amplified via an AC coupling. As the result of experiments, it was found that the average of the input success rate and the average of the input character number per a minute in real-time eye-glance input at the experimental display design was 91.5% and about 15.2 character for 10 subjects.
