博士 === 國立臺灣科技大學 === 工業管理系 === 106 === The promising technologies of stereoscopic displays have become popular and importance for many applications including training, education, surgery, military training, and vision research. These applications need further investigation to improve the usability and performance. Few literatures explore about the hand and eye performance in stereoscopic displays. This study aims to explore eye movement behavior during hand and eye coordination in stereoscopic displays. Twelve participants performed multidirectional tapping task. The experiment was conducted with three different levels of depth and six levels of index of difficulty in real and stereoscopic displays. The results revealed that environment had a significant effect on hand and eye movement time, index of hand and eye performance, time to first fixation, eye fixation accuracy, eye ballistic phase time, eye correction time, and pupil size. The results of index of difficulty found that there were significant main effects between index of difficulty and hand movement time, error rate, eye fixation accuracy, eye ballistic phase time, eye correction time, and pupil size. Moreover, different level of depth did not influence eye movement behavior of participants except pupil size. We found that participants prefer to perform the tapping task with depth 210cm in real and stereoscopic displays. The closer the target perceived to participants’ eyes will increase the severe symptom of eye, head, back and neck. The findings of the study can be considered to improve the users’ performance in stereoscopic displays.
