摘要

觸覺地圖對於視力受損者認識周遭的環境十分重要，本研究針對可能影響觸覺地圖引導績效的三種因素（路徑線條、距離點字、以及方向符號）進行實驗，16位不同程度的視力受損者使用不同因素水準組台的觸覺地圖，在特定的校園環境中進行觸覺地圖引導認識校園的實驗，實驗過程中記錄受測者觸摸地圖的「觸摸總時問」、「行走速率」、以及「偏移距離」等種引導績效資料。以MANOVA分析盡現，有各徑線條的觸覺地圖產生顯著較低的平均「偏移距離」，其餘兩種因素的影響並不顯著，研究結論將適用於未來觸覺地圖的設計參考。

Tactile maps are important tools for visually impaired persons to explore the environment they face. This study focused on three potential factors that affect the performance of guiding the way for the visually impaired persons. Sixteen participants with different visual states, gender, and Braille experience tested several tactile maps combining factors of trail line, distance Braille, and direction mark. Three guiding indices including exploration time on map, walking speed, and trail deviation were measured. The results of MANOVA test showed that using map with trail line had the lower mean trail deviation than using map without trail line. Nevertheless, no significant difference was found in the walking speed and exploration time. The other two factors had no significant effects on all performance indices. The experimental results of this study provide some insights for designing tactile maps.
