| Outline of Final Research Achievements |
In this study, we evaluated the relationship between concave stimulation and tactile readability, which has insufficient academic knowledge, and investigated the characteristics of tactile reading movements for concave stimulation on tactile graphics. We examined the production method of concave lines on graph paper and conducted a preliminary experiment on the spacing between concave lines and tactile readability using test pieces. In the second and third years, based on the results, we conducted a main experiment on the spacing between parallel concave lines on the x-axis or y-axis and tactile readability and analyzed in detail the influence of the distance between convex and concave lines on tactile readability. In the final year, we discussed with experts and clarified the characteristics of appropriate tactile reading movements, such as tactile speed and force, for identifying convex and concave lines, albeit in a simplified manner．

視覚障害者にとって有用な触図においては，表現のバリエーションを増やすために，凹状の点や線の刺激が触図では用いられることがある．しかし，凹刺激の識別容易性に関する学術的知見が不足している．そこで本研究では，凹刺激と識別容易性の関係を評価し，凹刺激の触読動作の特徴を明らかにした．こうした凹刺激の識別容易性や触動作の特徴の知見を基盤とすることで，より識別容易性の高い触図の表現法の検討を行うことができるであろう．
