中文摘要 | 由於閱讀電腦螢幕所引起的視覺疲勞比傳統文件要高,本研究將利用兩種不同的 閱讀休息方式(即工作100分鐘╱休息20分鐘(A水準)和工作50分鐘╱休息10分(B水準)) 來比較其瀏覽績效與視覺疲勞度。此外,為了瞭解瀏覽績效和視覺疲勞之間的動態關係,將 使用多變量時間序列模型來描述並預測使用者未來之瀏覽績效及視覺疲勞趨勢,續以多變量 時間序列品質管制圖監控整個瀏覽過程之平均瀏覽績效及平均視覺疲勞。研究結果顯示,兩 種工作╱休息策略下之平均瀏覽績效並無顯著差異,然而工作50分鐘╱休息10分鐘之平均 視覺狀態較工作100分鐘╱休息20分鐘為佳;最後配合多變量時間序列品質管制圖之觀察, 評定工作50分鐘╱休息10分鐘之工作╱休息策略(B水準)優於工作100分鐘╱休息20分 鐘(A水準)。 |
英文摘要 | In this study, multivariate time-series models will be implemented to illustrate and forecast the trend of user's browsing performance and visual fatigue as working time going. Besides, multivariate time-series control charts for monitoring the mean browsing performance and mean visual fatigue will be proposed as well in this study. The results of experiment indicated that Vector AR (1) and Vector AR (2) models were respectively fitted by A (100-min. work/20-minl. Rest) and B (50-min. work/10-min. rest) levels of the experiment. In addition, there are no significant difference in mean browsing performance between A and B work/rest strategies, however, mean visual fatigue for B (50-min. work/10-min. rest) strategy is much better than A. Consequently, it could be evaluated by multivariate time-series control charts that browsing performance of work/rest strategy B is better than A for computer users. |
