| Outline of Final Research Achievements |
We implemented and improved a head-mounted display for diving, introduced and optimized an underwater motion capture system, and investigated a body pull-back mechanism in water. As a result, high-precision tracking and high-quality visual feedback in a 4m x 4m range were achieved in shallow water less than 2m deep. User tests indicated that the implemented system had no problems with wearability and could provide a highly realistic underwater experience.
In addition, by combining visual stimuli with a pull-back mechanism, we were able to design a method that allows infinite sea travel within the above range. In the area of biometric sensing, we developed a prototype of a waterproof sensor for heartbeat and gaze, and verified its operation in water.

| Academic Significance and Societal Importance of the Research Achievements |
本研究成果から，潜水状態のユーザの位置姿勢が高精度・低遅延でフィードバックされる高品位な水中バーチャルリアリティ体験を世界で初めて実現した．これにより，実地訓練に頼らざるを得ない潜水作業者，ダイバー，救助隊等に対して効率的な訓練を提供し，安全性と技術力向上に大きく寄与する．
また，無重力・低重力下における人の知覚特性が容易に検証可能となることから，知覚心理学分野の発展に大きく寄与する．
