| Outline of Final Research Achievements |
In this research, a training system for inexperienced patients of crutch walks were developed. With the developed system, such patients were expected to acquire an expertise in crutch walks.The system consists of FSD (Falling Sensation Device) and HMD (Head Mounted Display); FSD was embedded into the crutch, and it was expected to present a sense to be falling. Since this perturbed the normal crutch walking motion, the patients were required to keep the body balance. The crutch user also wore a HMD while a walk training. When a virtual obstacle, which resembles a rolling ball, was presented on HMD during a walk training, the user could see the obstacle as if it appeared in his/her path.
Experiments for evaluation of the developed system were conducted. The participants were expected to land the uninjured leg as soon as possible, ceasing to walk and standing still. The results showed the possibility of contributing to the crutch walk trainings of the developed training system.

| Academic Significance and Societal Importance of the Research Achievements |
急に下肢を負傷し治癒までの間の歩行に松葉杖を使用する，いわば松葉杖歩行の初心者のための訓練装置の開発を目指した．なぜなら，松葉杖の正しい使用方法を知らないまま試行錯誤的に使用すると，使い方に誤った癖が付いてしまったり，転倒など二次的な事故の原因となりうることが問題とされるからである．
開発したシステムを用いて被験者に訓練してもらった結果，早く松葉杖歩行に慣れる傾向を確認した．このことより，本研究で提案したAR（拡張現実）技術を用いた訓練方法の意義と可能性を確認した．
