摘要

本論文提出一個新型圓頂狀頭戴式顯示器系統 — Dome+，使用了9個面板拼接而成之顯示器，提供215度超廣水平視野來產生沉浸式的虛擬實境體驗。藉由計算不同使用者之頂點距離與視覺調節力，讓近視與沒近視之使用者皆不需戴眼鏡即可使用Dome+系統，同時也消除一般使用於頭戴式顯示器中透鏡散射所產生的色差問題。此研究也提出幾種原型應用，及利用統計方法威爾克森符號等級檢定，評估雙眼立體視覺顯示器與非立體視覺的大視野彎曲顯示器在虛擬實境體驗中的沉浸程度，得到了即使沉浸傾向低的使用者也能在Dome+系統之超大角度視野下產生自然三維效果(Natural 3D effect)，感受到立體感且更加身歷其境。本篇論文提出的超大角度視野頭戴式顯示器系統，在虛擬實境中提供了一個新方式來達到更加的沉浸式經驗。

This thesis presents a novel dome-shaped head-mounted display (HMD) system, called Dome+, which uses 9 tiled panels for display to offer an ultra wide field-of-view (FoV) of 215 degrees for an immersive virtual reality (VR) experience. By calculating the vertex distance and the accommodation power of users, those who have myopic eyes or normal eyes can use Dome+ with their bare eyes; therefore we can eliminate the chromatic aberration artifacts which happened in current HMDs caused by lens dispersion. This work also introduce several prototype applications and use the non-parametric statistical analysis of Wilcoxon Signed Rank Test to analyse how immersive between the stereo display and the non-stereo, wide FoV curved display VR experiences. The results show that Dome+ offers a natural 3D effect even for those who have the weak tendencies to become involved in and so can feel stereoscopic effect. The proposed ultra wide FoV HMD system provides a new solution to achieve a more immersive VR experience.
