Operation Support of Electric Wheelchair by Gaze Amount Histogram

Abstract

In this research, we examined an operation support method by gaze input using gaze amount histogram. In order to accurately identify the direction the user wishes to move and the direction which the attention is directed, in the gaze driving, estimation system based on the gaze amount histogram was constructed and a running experiment was performed. As a result, showed no significant difference in the traveling route compared to the conventional method, but the subjects' questionnaire resulted in a higher score than the conventional method in terms of safety. Therefore, it was possible to confirm the effectiveness of the operation support method using the gaze amount histogram.
