觸覺是所有感覺系統中發展最早，分布也最廣。藉著觸覺，兒童（Children）可了解自己和環境的關係，藉著經驗累積，培養兒童認知、並幫助其視覺的發展。目前觸覺（Tactile Sensation）研究大部分為解決視障者的問題為主，但是現代許多的科技產品具有觸控式的設計。而這些產品設計的基本造形莫過於以基礎幾何形體（Geometric Forms）為主或變化形成的造形，因此造形的認知與知覺訓練的提升將有助於未來與觸覺產品的互動。 有鑑於此，本研究將探討兒童在無視覺輔助情況下，觸覺感官與基礎造形（圓形、三角形、正方形、多邊星形）認知（Cognition）關係之辨識度，探討兒童對形體的辨識能力與學習效果，並得到如下之結果：1.兒童對於基礎幾何形體（2 D及3D）之實體樣本模型，其觸覺辨識反應隨著年齡的增加，觸覺反應相對提高，但是在相對與絕對判斷中年齡的影響並不顯著。另外，在學習方面，次數的增加也會減少失誤的機率。2.2 1/2 D的觸覺辨識比3D的實體辨識為佳。3.幾何形體的特徵差異越大，兒童觸覺對於形體辨識認知能力也較佳。4.可藉由人因之完全餘備觀點來輔助設計，藉此提高兒童在觸覺學習上的辨識能力。5.兒童慣用手之觸覺辨識（Identification）能力較高，但是非慣用手經由學習後，其辨識能力明顯增加。 最後，期能藉此觸覺學習的研究結果，能在兒童產品開發設計與幼兒教育發展方面，提供良好的設計參考價值。 The development of a tactile sensation is the earliest and its distribution is also the widest in all sense organs. Children can understand the relation between themselves and environment through a tactile sensation. As experiences accumulate that can train children's cognition and assist their visual development. Most of the tactile researches mainly solve the difficulties which blind people met, but present products with high-technology have tactile design and their basic forms are geometric patterns or the variation of geometric forms. Therefore, the improvement in form’s cognition and perceptive training will help the interaction between people and products in the future. On the basis of this concept, the study will investigate that when children are in a non-visual assistant situation, the recognition of cognitive relation of tactile sensation and basic forms including circle, triangle, square, and polygonal star and discuss children’s identifiable abilities and learning effects regarding forms. The result shows as follows:1.In the patterns of basic geometric forms (2 D and 3D), as children's age increases, their tactile identifiable reactions also increase. But the age’s effect is prominent in comparative identification and absolute identification. In addition, the decrease of the probability of fault accompany with learning increasing frequency.2.The tactile identification of 2 D patterns are better than 3D Patterns.3.The characteristics of geometric forms are more different, the form identifiable abilities of children's tactile sensation are better.4.Design by the completely redundant concept can improve children identifiable abilities in tactile learning.5.The identifiable ability of children's habitual hand is better. But the identifiable ability of non-habitual hand obviously increases after learning. Finally, the study expects that the result can provide a superior reference in children product development design and infant educational development.
