早期視覺評估有賴具專業背景人士的判斷，可能流於主觀，且亦無法反映大眾之意見，本研究應用國際照明學會所提出的色差公式，測量建築物與背景之對比程度，並以瞳位追蹤儀紀錄受測者觀看區域的凝視次數，再以問卷詢問受測者感受到的明顯程度與偏好程度，檢視凝視次數與明顯程度及偏好程度間的關係，並分析色彩對比與受測者感受到的明顯程度之關係。研究結果顯示，凝視次數越高，受測者感受到的明顯程度也越高，色彩對比越大，受測者就感到越明顯，且凝視次數也就越高。

In earlier studies, visual assessment rely on professional judgments. It may be too subjective and can't reflect public's opinions. This study uses color difference formula suggested by International Commission on Illumination to measure contrast between building and its background. The eye tracker is used to record fixation counts in area of interest and respondents were requested to answer questions about their perceived obviousness and preference. This study examines the relationships among fixation counts, obviousness and preference, and analyses the relationship between color contrast and the obviousness perceived. Result shows the higher fixation counts, the higher obviousness is perceived. The higher color contrast, the higher obviousness is perceived and the higher fixation counts.
