| Outline of Final Research Achievements |
This research is related to “Motion-lessVR,” a body-fixed immersive VR interface, and we pursued technological development on how to solve the problem of immobilization (i.e., how to enable the perception of motion exertion and sensation similar to that of unfixed free motion). In particular, the application of posture-based torque conversion, which we have been working on to eliminate the discomfort of kinetic motion, was shown to be effective in situations where there is a discrepancy between the fixed and virtual postures, but a new problem emerged: the kinetic motion is also affected by the sensory perception, and the effect of the kinesthetic illusion diminishes with posture discrepancy. Without a dramatic improvement in the performance of the kinesthetic illusion or in combination with sensory numbing techniques such as cooling, it was found to be difficult to achieve sufficient motion at a certain posture.

メタバースなどに期待が集まる昨今においても，視聴覚でのVRが主であり，リアルな運動を再現できていない．これは，多様な環境であらゆる運動を可能とする没入型VRシステムが物理的に困難であることに起因している．そこで，身体固定状態とすることで環境による制約を取り除きつつも，運動錯覚技術などで自由運動と遜色のない運動感覚を持たせることを提案システムでは志向した．各要素技術の進展次第では本システムは有用なものとなり得ることが示唆された一方で，現時点においては一部要素技術（特に運動錯覚技術など）の性能が没入型VRシステムとして十分な運動性能を発揮するには不十分である事なども判明した．
