Abstract
In this study, we propose a non-contact input device using only eye movement without the calibration for correcting the gaze direction. The traditional input device using eye positional information requires head movement. However, the severely disabled people who are unable to move their head, e.g. amyotrophic lateral sclerosis, are difficult to use this device. Although an eye-gaze input device does not require the head movement, the calibration to correct gaze direction induces the degradation of usability. The proposed system allows users to control a mouse cursor of a personal computer using only eye movement. The mouse cursor control method using the distance between the center position of pupil and reference point eliminates the need for head movement and calibration. The experiments were performed to evaluate the operational performance and usability of this input device. From the experimental results, the operation time became shorter with the increase of trial numbers. In addition, the parameter setting for respective individual improved the operational performance of the input device.
