本研究以兩階段的 實驗設計來進行赫曼方格錯視現象產生，主要目的在探討方與距的比關係對此錯視現象的影響，並且了解色彩色相的變變對此錯視強度的差異性。 本實驗主要結果如下： 可以產生赫曼方格錯視現象的方格與間距關係比為1:0.75，也就是方格與間距面積比為4:3時，灰點就會被看見。 從統計結果之變異數分析可知，p-value<0.05有顯著差異，色彩會影響赫曼方格的錯視效果。 色彩對赫曼方格錯視效果由強到弱的排列：黑>灰>紅>紫青>綠>青>紫>黃紅>紫紅>黃綠>青綠>黃(序位平圾值為1.42，3.49，4.28，4.65，5.58，5.95，6，6.79，7.98，9.98，10.12，11.77)。 研究結果可落實到介面設計或交通安全管理方面之應用，讓使用者提高判斷之正確率，也可以在介面安全之設計上，降低駕駛錯視或發生危險之機會。

There are two stages to design the experiment of Herman grid illusion. The main purpose of the study is to detect the percentage relationship of grids and aisles. And we try to understand the different illusive effect of changing colors. The results are below: The percentage relationship of grids and aisles is 1 to 0.75. It means that the square areas of them are four to three then the gray point will show. From the analysis of variance we find that it has significant Hermann grid illusive effect as the colors change because of the value smaller than 0.05. The color ranks of the Hermann grid illusion are black, gray, red, purpleblue, green, blue, purple, yellowred, purple, greenyellow, bluegreen, and yellow. The results can apply to interface design or the traffic safety management. We hope that the drivers can raise the correct judgment rate and use the design of interface safety to decrease the illusion or protect from danger.
