摘要

在立體顯示器的軟體、硬體設備上，仍有許多需克服的問題，如垂直解析度、水平解析度、視角以及亮度等。從3D立體顯示技術看來，戴眼鏡及頭戴式的技術，雖然已經是成熟的技術，但目前仍無法廣泛的應用，對使用者而言，多了一個頭戴裝置，一般人還是不習慣。因此，除了一些大型的3D立體劇場或特殊的訓練應用外，較難進入消費性市場。近年來推出的裸眼型立體顯示器則消除了戴眼鏡或頭戴裝置的障礙，但使用者在長時間觀看立體圖像或影片，常會抱怨有頭暈、嘔吐等不舒服現象。
「交錯殘影」是影響立體影像品質最重要原因，也是視覺疲勞的主要來源之一。為了得知在不同因子之「交錯殘影」程度，本研究將以兩種人因評估方式，主觀問卷評估及創新的交錯殘影模擬器評估技術，對裸眼型立體顯示器影像品質之相關因子做一探討。
由實驗結果得知，兩種評估技術均具有良好的解釋能力，並期待未來能完整建立影像品質之於「交錯殘影」與各因子的資料庫，做為立體顯示器產業之參考。

Many problems of 3D stereoscopic display have not been solved, such as vertical resolution, horizontal resolution, viewing angle and brightness. Moreover, it is not convenient for users to wear a device or helmet as using stereoscopic display. These years, autostereoscopic displays can present 3D stereoscpic images to the viewer without wearing glasses or any device. However, after long-time of using the autostereoscopic display, users complained about having dizziness, vomiting and uncomfortable phenomenon.
“Crosstalk” is probably one of the most annoying distortions in 3D displays and the main resource of visual fatigue. In order to understand the level of “crosstalk” in different factors, the research will analyze the factors related to crosstalk through ergonomics evaluations in autostereoscopic displays, including subjective evaluation for questionnaire and the innovative method - Simulation of Crosstalk.
The result of this research revealed that two types of the evaluation methods had great explanatory ability. It is demonstrated that the database for the stereoscopic image quality will be build, and may provide the industries of 3D display with critical references.
