 note = {実用的な手指形状推定システムを構築するための知見を獲得するため，ヒトが手指の形状を理解する場合に用いる視覚的手掛かりを実験的に検討した．本研究では，とくに手の皺，爪，皮膚の色に注目した．実験ではまず，各被験者が手の画像の形状を認識できる最小の提示時間が測定され，決定された．次に，3種類の視覚的手掛かりのうちの1つが強調，抑制，あるいは解剖学的矛盾を伴って付け加えられた手の静止画像が提示された．被験者は，観視した手の形状を答えるように求められた．実験の結果，3種類の視覚的手掛かりにおける関与度の比率は，爪が25％，皺が20％，皮膚の色が15％であった．, For the purpose of acquisition of the knowledge to construct the practical computer vision for hand posture estimation with, the authors experimentally investigated the visual cues in understanding of the shape of human hand. In this paper, we discussed mainly on the wrinkle, nail, and color of the hand skin. In the experiment,the minimum time for presentation of the hand image was measured beforehand and fixed in each subject, in which he or she can recognize the shape. Then, the editted images of the human hand were presented, where one of three cues were emphasized, decreased, or added with anatomical contradiction. The subjects were instructed to answer the hand shape that he or she observed. As the results, the contribution ratios of the visual cues were 25% in nail,20% in wrinkle, and 15% in skin color, respectively.},
