摘要

科技的進步與技術層面的演繹，促成平板電腦的誕生，象徵著行動資訊時代來
臨。其便利性開啟了電子化閱讀的新起點，提供使用者全新的閱讀模式及高機動
性的閱讀環境。然而便利的產品優勢，改變使用者的用眼習慣，將導致視覺疲勞
產生。本研究探討平板電腦螢幕色彩組合與視認性及視覺疲勞的相互關係。將色
彩以有彩色R、G、Ｂ及無彩色黑、 白之組合。環境光線設定在低照明度的黑暗空
間。 探討平電腦螢幕色彩組合對視認性及視覺疲勞的影響。
本研究實驗部份分為：1）螢幕色彩組合對視認性的影響2）螢幕色彩組合對視覺
疲勞的影響，兩個階段。實驗一結果顯示，在黑暗環境下藍底綠字視認性最佳；
黑底綠字最差，且受距離、顏色樣本、樣本極性及目標物面向的變項影響。實驗
二，分成視覺疲勞和視覺績效兩方向探討。視覺疲勞以主觀疲勞問卷及客觀HFC
差值交錯分析。視覺績效則以目標物搜尋、理解力是非題、閱讀速度三項分析之。
結果顯示，黑暗環境下視覺疲勞部分，白底黑字為視覺疲勞最輕微的顏色組合；黑底白字為最疲勞的顏色組合。視覺績效部分，白底黑字表現最佳；黑底綠字和綠底藍字表現最差。本研究發現在黑暗環境下閱讀最佳顏色組合。反觀螢幕呈現黑底白字/黑底綠字/綠底藍字隻顏色組合都應避免在黑暗環境下閱讀。

With the growth of computer technology and screen technique, reading with Tablet PC becomes a new trend. The colors combinations of environment affect the reading-using tablet PC. Therefore the study focused on how the combinations of text colors influent visual while reading tablet PC in dark environment.
The whole experiment was divided into two sections, which are the legibility and the subjective assessment of visual fatigue affected by the combinations of colors. The color combinations are black, white and R.G.B color model.
This study in experiment 1 shown that the best of legibility in dark environment is blue background with green word (herein referred to as “BL/G”) and black background with green word (herein referred to as “BK/G”) is the worst for legibility in dark place. Besides, the legibility is affected by the distance.colors combinations.polar and object of directions.
The results in experiment 2 indicated that W/BK is the best for visual fatigue and the worst is BK/W in dark environment .During the subjective visual fatigue 9-point scale. W/BK is the best and the worst is BL/G. In addition, W/BK is the best for visual performance,and the worst is G/BL and BK/G in dark environment.
In summary, this study discovered that there should be different color combinations, when people are reading with tablet PC in dark environment. And there are differences between the subjective and objective visual fatigue. The results provided a reference to mitigate visual fatigue of the reading in dark place.
