本研究以兩個實驗探討電子紙顯示器螢幕在各種顯示條件下對視覺作業的影響。
實驗一在探討光源、照明度及字體高度,對電子紙顯示器之最適視距與最適視角的影響。實驗結果顯示,平均最適視距為49.4 cm,平均最適視角為123.4°。光源對最適視距影響不顯著,但對最適視角有顯著影響。D65日光燈和TL84螢光燈的最適視角差不多,但F鵭絲燈的最適視角較小。照明度和顯示媒介對最適視距和最適視角的影響顯著,照明度愈高,最適視距愈長,最適視角愈小。顯示媒介的平均最適視距與平均最適視角分別為:Kolin膽固醇液晶顯示器 (50.0 cm, 127.4°),Sony電子墨水顯示器(49.1 cm, 120.0°),普通紙張(49.0 cm, 122.9°)。字體高度對最適視距的影響顯著,但是對最適視角的影響不顯著。本研究結果顯示平均最適視距為49.4 cm,字體愈大,視距愈長,電子紙的視距與VDT螢幕之視距雷同,大約為50公分,有別於正常閱讀書本之距離36 cm。平均最適視角大約為123.4°,當電子紙顯示器的視距為50公分,眼睛離桌面的垂直距離平均為34 cm時,平均最適注視角度位於眼睛水平線下29.5°,符合一般視覺顯示器位於眼晴水平線下約20°至50°間。
實驗二在探討光源、環境照明度及字體高度對電子紙顯示器之視覺績效與視覺疲勞的影響。實驗結果顯示,環境照明度對搜尋時間影響顯著,照明度愈高,搜尋時間愈快;字體高度對搜尋時間影響顯著,字體高度愈大,搜尋時間愈快。照明度與字體高度之間的交互作用效果顯著,搜尋時間都是1500 lx時最快,700 lx次之,300 lx最慢。但是三個照明度下的搜尋時間差異隨著字體高度的變小而逐漸加大。當字體高度為1.4 mm (視角為9.6 min)時,差異顯著變大。光源與環境照明度對辨識正確率的影響不顯著。字體高度對辨識正確率影響顯著,字體高度1.4 mm (84.1 %),其辨識正確率最低。2.2 mm (視角為15.1 min)、3.3 mm (視角為22.7 min)和4.3 mm (視角為29.6 min)這三種字體高度彼此之間在辨識正確率上無顯著差異。
對於受試者的視覺疲勞,實驗結果顯示,光源和顯示媒介兩者均對CFF的變化影響不顯著。視覺疲勞的另一個指標-受試者的主觀視覺疲勞,它與光源類型顯著地無關,但是它與顯示媒介顯著地有關。光亮度對比在視覺疲勞上可能扮演一個重要的角色。
Two experiments were conducted to electronic paper (E-Paper) displays under various working conditions in this study.
The first experiment investigated the viewing distance and screen angle for electronic paper (E-Paper) displays under various light sources, ambient illuminations, and character sizes. Data analysis showed that the mean viewing distance and screen angle were 49.4 cm and 123.4°. The mean viewing distances for Kolin Chlorestic Liquid Crystal display was 50.0 cm, significantly longer than Sony electronic ink display, 49.1 cm. Screen angle for Kolin was 127.4°, significantly greater than that of Sony, 120.0°. Various light sources revealed no significant effect on viewing distances; nevertheless, they showed significant effect on screen angles. The screen angle for sunlight lamp (D65) was similar to that of fluorescent lamp (TL84), but greater than that of tungsten lamp (F). Ambient illumination and E-paper type had significant effects on viewing distance and screen angle. The higher the ambient illumination was, the longer the viewing distance and the lesser the screen angle. Character size had significant effect on viewing distances: the larger the character size, the longer the viewing distance. The results of this study indicated that the viewing distance for E-Paper was similar to that of visual display terminal (VDT) at around 50 cm, but greater than normal paper at about 36 cm. The mean screen angle was around 123.4°, which in terms of viewing angle is 29.5° below horizontal eye level. This result is similar to the general suggested viewing angle between 20° and 50° below the horizontal line of sight.
The second experiment investigated effects of light source, ambient illumination and font height on visual performance and visual fatigue with electronic paper (E-Paper) displays. The results showed that ambient illumination significantly affected search time. The higher the ambient illumination was, the faster the search time. Font height had significant effects on search time. The greater the font height was, the faster the search time. The ambient illumination × font height interaction was statistically significant on search time. 1500 lx was the fastest of the three, 700 lx was the second, and 300 lx was the slowest. But the difference of search time under three illuminations was strengthened gradually as font height was diminished. When font height was 1.4 mm (viewing angle is 9.6 min), the difference became great apparently. Light source and ambient illumination had nonsignificant effects on correct percentage. Font size had significant effects on correct percentage. Font size 1.4 mm (84.1 %) was the lowest of all on correct percentage. 2.2 mm (viewing angle is 15.1 min) , 3.3 mm (viewing angle is 22.7 min) and 4.3 mm (viewing angle is 29.6 min) had nonsignificant effects on correct percentage.
In terms of visual fatigue, results showed that both light source and display medium had no significant effects on the change of CFF (Critical Flicker Fusion). Subjective visual fatigue was not significantly related to light source, but significantly related to display medium. Luminance contrast may play an important role on visual fatigue.
