| Outline of Final Research Achievements |
We conducted experimental studies on visual motion information processing and its effect on perception and postural control. First, through psychological experiments using a head-mounted display, we obtained a series of results regarding the relationship between the perceived self-motion (vection) unconscious body sway induced by optic flow stimuli. Second, we examined the perceptual characteristics through psychophysical experiments using more basic visual motion stimuli, some of which were published as collaboration with National Taiwan University. Furthermore, we used fMRI to investigate the brain network underlying optic flow processing, but due to the covid-19 pandemic during this research period, we only obtained pilot data that provided suggestions for future research.

| Academic Significance and Societal Importance of the Research Achievements |
視覚運動情報処理は日常生活における自己あるいは対象物の移動に伴って常に生じていることであり、その理解は生活の質を向上させるための基礎的な課題といえるだろう。その点では本研究の成果は漸進的であり、直ちに新しい理論や応用技術につながるとまではいえない。一方、ヘッドマウントディスプレイに関する知見、特に立位と座位で身体応答が大きく異なるという新事実や、上下視野による違いを示したことは、VRゲーム等のアプリケーションの効率的な設計、また、自動車運転などにおけるAR、MR的情報提示のデザインなどに寄与する可能性があるだろう。
