| Outline of Final Research Achievements |
This research aims to provide information accessibility support for visually impaired to perform actions and behaviors that recognize objects by themselves or reflect their understanding of the situation. Therefore, we plan to develop an object recognition method for them to improve the shape understanding of the target recognition object by touch virtual haptic senses created from a pseudo-object in a computer. In general, the shape information of an object is difficult to verbalize. Even if its information is transformed into spoken words, it is hard to understand the shape of an object through hearing. Therefore, it is necessary to expand context awareness into 2D or 3D contexts while collaborating with visually impaired who rely on haptic sensation. In this report, for pseudo-objects created by combining 2D and 3D basic shapes in a computer, we consider the processes of shape understanding and object recognition under visually impaired conditions based on virtual haptic senses.

| Academic Significance and Societal Importance of the Research Achievements |
視覚障碍者と晴眼者との間の情報獲得格差はウェアラブルセンシングの発達に伴ってさらに広がると予想される。１人称視点映像のリモコン画像からテレビを見るという行動認識を推定して番組表を提示するといった未来も間近に迫っている。しかし，視覚障碍者は１人称視点映像を取得できず，仮に代替方法で取得できたとしても行動認識を誘起させるには触知によるオブジェクト形状の伝達は必須である。視覚障碍者自身が対象オブジェクトの触知が簡単に行え，それを行動認識に利用することは，環境の状況把握や学習への行為を含めて，様々な視覚障碍支援に応用することができる。
