視覺是人們最主要接收外界資訊之感官，但對於視覺障礙者則不是如此，視覺障礙者對於接收外界的資訊大多以聽覺、觸覺為主。當視覺障礙者閱讀書籍，日常生活中以盲文點字為主，且無圖形搭配文字輔助。因此觸覺圖形卡是觸覺圖形轉化為資訊，讓視覺障礙者理解圖形的方法。若圖形過於複雜，影響他們辨別的資訊。本研究建構出視覺障礙者對於基本的觸覺圖形辨識和圖形形狀建構之能力的準確率和反應時間。研究結果能提供視覺障礙者之觸覺圖形訓練輔具設計參考依據，進而設計視覺障礙者形狀訓練之相關產品。

Vision is the most important sensory sense of people receiving external information, but it is not the case for visually impaired people. The visually impaired people mainly listen to and receive information from the outside world. When visually impaired people read books, Braille is the mainstay In daily life, and there is no graphics matching with text., a tactile graphics card is a method in which a tactile graphic is converted into information, allowing a visually impaired person to understand the graphic. If the graphics are too complicated, they Will affect the information they identify. The study constructs the accuracy and response time of visually impaired people's ability to identify basic tactile patterns and shape shapes. The research results can provide the reference for the design of tactile graphics training aids for visually impaired people, and then Design related products for visually impaired shape training.
