Abstract(in Japanese) (See Japanese page)
Abstract(in English) In this paper, the relationship between human's pupil size and difficulty of input operation was examined. We prepared three type of input devices as the pointing device; mouse, cursor keys and a small remote controller. A simple pointing task was given to subjects and their pupil size were measured during the task. Comparing the usability score which estimated by questionnaires and average pupil size, there were a strong negative correlation between them. And we also compared error rate of the task and average pupil size. Then it was found that the error rate and average had a strong positive correlation. Additionally, it was suggested the temporal pupillary change depended on input device.
