| Outline of Final Research Achievements |
In this study, we focused on "near/far point of eye accommodation" and "the size of visual field" while viewing stereoscopic video clips. We developed a mathematical model to determine the biological condition while unpleasant symptoms are induced. As a result, we found that visual field constriction in the augmented environment did not have a significant effect on the autonomic nervous system. Our analysis of the cerebral blood flow (CBF) showed that the visual field constriction had a remarkable effect on the CBF. Also, it is possible that the visual object could not be processed precisely due to the effect of increased visual cue speed while viewing stereoscopic video clips for each speed in the visual cue. In addition, we have succeeded in findings of an artificial intelligence model for eye movement based on CNNs to discriminate between the peripheral and the central visibility with eye tracking on the visual cue.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の研究成果は、立体映像やVR/AR、超高精細映像と言った映像視聴時の生体評価にとどまらず、衛生学・人間医工学分野において貢献できる。また、視野狭窄が脳血流に及ぼす影響や、視標速度が異なる立体映像視聴における生体状態の変化は、今後、メタバースなどにおける3D映像やヘッドマウントディスプレイの利用増加が見込まれる中、当該分野の発展や安全性の向上に寄与するものである。
