受動的力覚誘導条件が空間位置の認知再生に与える影響の評価 Evaluation of the Effect of Passive haptic-guidance Conditions on Cognitive reproduction of Spatial Position. 坂井, 忠裕 大西, 淳児 坂尻, 正次 松尾, 政輝 三浦, 貴大 Tadahiro, Sakai Junji, Ohnishi Masatsugu, Sakajiri Masaki, Matsuo Takahiro, Miura 視覚障害支援 筆者らは，視覚に障がいのある人が教材や美術品などの立体情報を迅速に把握することや，球技ボールなどの 3 次元空間で移動する物体の軌道を伝える空間力覚誘導提示システムを開発している．本システムでは，空間内で指を機械的に牽引する受動的な力覚誘導を用いることで，通常の自由触察だけでは伝えにくい立体教材の内容理解の支援，移動物体の位置や軌道を直接実時間で伝達することを目指している．本報告では，空間力覚誘導の速度や移動位置の滞留時間を要因とする誘導条件が，自己受容感覚を基に力覚誘導された空間位置を認知再生した場合の位置精度に与える影響を評価した．その結果，誘導直後の再生において，再生誤差は平均値で 30～40mm 程度生ずることがわかった．また，誘導速度と滞留時間との関係には交互作用の傾向があり適切な誘導速度があることが示唆され，空間位置の認知再生の誤差が小さくなる力覚誘導条件の指針を得た． We have been developing a spatial haptic-guidance presentation system that allows visually impaired individuals to quickly grasp three-dimensional information such as educational materials and art works, as well as convey the trajectory of objects moving in 3-D space, such as a sports ball. By using passive haptic-guidance in which a finger is mechanically pulled in space, this system aims to support understanding of the contents of 3-D educational materials, that is difficult to convey by ordinary free touch alone, and to directly convey the movement and trajectory of moving objects in real time. In this report, we evaluated the effects of induction conditions that factor in the velocity of spatial haptic induction and the dwell time at a moving position on positional accuracy when reproducing the haptically induced spatial position based on proprioception. As a result, it was found that the average error in reproduction immediately after induction was about 30 to 40 mm. Additionally, there is a tendency of interaction between induction velocity and dwell time, suggesting the existence of an appropriate induction velocity, and we obtained a guideline for haptic guided induction conditions that reduce the error of spatial positions on the recognition and reproduction. 情報処理学会 2024-03-11 jpn technical report https://ipsj.ixsq.nii.ac.jp/records/233177 2432-2431 AA12752949 研究報告アクセシビリティ（AAC） 2024-AAC-24 5 1 6 https://ipsj.ixsq.nii.ac.jp/record/233177/files/IPSJ-AAC24024005.pdf application/pdf 1.9 MB
