| Outline of Final Research Achievements |
The purpose of this study is to develop a highly practical simulator with high immersive and realistic functions by using a wheelchair simulator with vestibular sensation presentation, wheelchair wheel force perception presentation, and a caster up/down mechanism. To this end, we first developed a mathematical model for visually presenting the position of the wheelchair, and verified its validity. We also proposed various methods to reduce VR sickness in situations where VR sickness tends to occur more strongly. The effectiveness and interaction effects of these methods were verified through evaluation experiments using a simulator that implements the methods.

本シミュレータを用いて，揺動感覚，力感覚および映像提示により得られる人の感覚認知機能と実際の車椅子操作における感覚との心理物理実験による比較検証を行い，ＶＲシステムとして必要となる感覚提示手法について明らかにした．また，ＶＲ酔いを低減しつつ現実空間を良好に模擬できる手法について実験により検証した．加えて，手動車椅子シミュレータに対して，力学モデルおよび心理物理実験の側面から評価した．本研究の成果は，構想段階の施設等の車椅子利用時の利便性を事前に評価できる実用的なシミュレータを開発し，車椅子利用者の社会進出を支援できる評価システムの確立に役立つものと考えられる．
