比較眼控介面與標準鍵盤滑鼠使用者之視覺疲勞出現時間

本研究探討使用眼控介面的視覺疲勞出現時間。我們分別使用市面上的兩種眼控介面設備（A廠牌即遊戲版眼控滑鼠、B廠牌即專業版眼控滑鼠），以及標準鍵盤與滑鼠（SKM）操作來進行比較。實驗測試工作包含打字、畫圖、購物三種電腦作業。本研究共招募30位年輕的自願者進行實驗。受測者年齡20歲以上，其中16名為男性，14名為女性。每位受測者進行9次試驗，試驗順序均採隨機方式進行。每次試驗約為60分鐘，其間固定每15分鐘的電腦作業即進行8分鐘的主觀疲勞調查和客觀疲勞時間的評估；如此重覆15分鐘電腦作業和8分鐘的評估，直到獲得受測者最終的眼睛疲勞出現時間為止。實驗結果得知：控制介面設備對於主觀疲勞出現時間（P < 0.01）及最終疲勞出現時間（P < 0.05）有顯著的影響，對客觀疲勞出現時間則無顯著影響。而電腦作業類型對三種疲勞出現時間皆顯示無顯著影響。結論是受測者在試驗後，在使用眼控設備所產生的疲勞出現時間(30min-35min)與SKM所產生的疲勞出現時間(40min)相比，大約快了10min產生視覺疲勞。證明眼控設備的使用，造成的疲勞相對於SKM是較快的。所以我們覺得，在設備的硬體或軟體上，未來還有很大的進步空間，如果能延緩出現疲勞時間，對於使用者會有很大的幫助。關鍵詞：眼控介面、疲勞出現時間、視覺疲勞、人機介面

This study investigated the time to visual fatigue using the eye controlled interface. We used two types of eye-controlled interface devices (Brand A is the game version of the eye controlled mouse, Brand B is the professional version of the eye controlled mouse), and the standard keyboard and mouse (SKM)in the experiment. The experimental tasks included three computer tasks: typing, drawing, and shopping. A total of 30 young volunteers were recruited for the experiment. The subjects were over 20 years old, including 16 males and 14 females. Each subject conducted 9 trials, and the test sequence was performed randomly. Each trial took about 60 minutes. During this period, an 8-minute subjective fatigue survey and objective fatigue time assessment were performed after every 15-minute computer operation. Repeat 15 minutes of computer operation and 8 minutes of visual fatigue evaluation until the subject reaches the final eye fatigue. The experimental results showed that the control interface equipment had a significant effect on the subjective fatigue time (P <0.01) and the final fatigue time (P <0.05), but had no significant effect on the objective fatigue time. The type of computer operation showed no significant effect on all three fatigue times. The conclusion was that the fatigue occurrence time (30min-35min) produced by using the eye controlled device was about 10min faster than the fatigue occurrence time (40min) produced by standard keyboard and mouse (SKM). It proved that the fatigue caused by the use of eye controlled mouse was relatively easy compared to SKM. Therefore, we think that there is still much room for improvement in the hardware or software of the eye-controlled mouse. If it can delay the time to the occurrence of eye fatigue, it will be of great help to users. Keywords: eye controlled mouse, fatigue occurrence time, visual fatigue, man-machine interface
