本研究主要在探索浮凸線段的觸覺錯覺現象，了解觸覺錯覺對於觸覺辨識績效的影響。受測者為矇眼明眼者15人，視障者( 先天盲者、後天盲者、弱視 )15人。其自變數為：浮凸線段長度 ( 9、11公分 )、浮凸線段形狀 ( 直線、弧線 )、干擾點形狀( 正方形、空方形、菱形、空菱形 )，干擾點位置( 左端位置、中央位置、右端位置 )，從中檢測受測者的辨識時間與長度偏差的變化。MANOVA分析顯示：浮凸線段長度愈長，辦識時間就愈長；以浮凸線形狀來說，弧線在長度偏差上容易高估；而當菱形及空菱形在右端位置的狀態時，其辨識時間均明顯長於其它干擾點形狀；空正方形在中央位置的狀態時，在長度上易高估。視力狀態在辨識時間上，先天盲者＞弱視者＞後天盲者＞矇眼者，在長度偏差，弱視者 > 後天盲者 > 先天盲者 > 矇眼者；點字訓練在辨識時間與長度偏差呈現（受過點字訓練＞未受點字訓練）。研究結果建議：在觸覺地圖的設計上，易造成觸覺錯覺的長度形狀組合應該加以避免，以減少產生的錯誤引導。

This research mainly explored the tactile illusion of tactile line by measuring the recognition time and the length prediction error. The subjects were 15 visually impaired individuals (including CB, LB, and LV) and 15 blindfolded persons. The independent variables were tactile line (length: 9 and 11 cm), line shape (line and curve), interrupt element (solid-square, empty-square, solid-rhombus, empty-rhombus), interrupt location (Left-end, Center point, Right-end). The MANOVA test indicated that longer line took significant longer recognition time; the curve shape significantly produced over-length prediction. The interrupt element of solid rhombus or empty rhombus located at the Right-end, the recognition time significantly longer than other condition; and the empty-squre produced significant over-length prediction. In the ‘eyesight status’ factor, it was found that ( CB > LV > LB > BF ) at the recognition time and ( LV > LB > CB > BF ) at the length prediction variable. In the ‘Braille training’ factor, it was found that (On-training > Untrained) at the recognition time and at the length prediction. The results reveal that some combination of element in tactile maps should be avoided for making the possible Tactile Illusions and the miss-leading follow those situations.
