摘要

近年來許多電子產品朝向可攜式、輕量化發展，使用者於振動環境中使用顯像裝置的機會增加。觀看振動畫面會導致視覺疲勞、辨識度下降、搜尋績效下降等問題。本研究提出顯像裝置之適視化模式，將振動模式區分為大幅與小幅振動，系統分析振幅類別，於小幅振動時進行影像補償，於大幅振動時重新定位參考原點。邀請30名受測者於振動模擬平台上進行模式驗證實驗，比較振動畫面有補償對無補償在視覺疲勞主觀問卷量表（心理）、閃光融合閾值（生理）及閱讀字數績效（客觀）及主觀意見四部分的差異，提出修正的適視化模式。

In recent years, many electronics devices have developed towards a portable and lightweight product. This may create an opportunity for the user when using an imaging device in a high-vibration environment. Watching a vibration screen can cause visual fatigue, decrease in identification, decline in search performance, and other issues. This study proposes a visual adaptation process for display device, where the vibration amplitude is divided into high and low vibrations. A systematic analysis was introduced to analyze the category for the amplitude. As a result, an image compensation method is suggested for low-vibration and reposition the reference origin for high-vibration. A total of 30 subjects were invited on a simulated vibration platform for model validation experiment. By comparing the vibration results in compensating mode and those without based from the four indicators, namely subjective visual fatigue questionnaire (psychological), critical fusion frequency (physiological), reading performance (objective), and subjective opinion, a refined visual adaptation approach is proposed.
