近年來360影像技術成熟、環景視覺介面帶給使用者逼真的沉浸式體驗，在商業、藝文展示、教育領域中處處可見多樣的應用。360影像顯示方式中，螢幕式虛擬實境(Screen-based VR)因具備經濟性、適合公共使用等特性，成為360內容顯示最常見的方式。面對螢幕式VR的實用與普遍性，評估該類型網站的使用體驗就顯得十分重要。由於線上藝文展覽應用360 VR日益興盛，本研究目的為探討以螢幕式VR 360影像展示的線上展覽網站的使用者經驗。本研究透過實驗評估使用者瀏覽不同線上展覽後，對於該虛擬展覽的展場空間感知效果。此實驗探討以下變項對使用者體驗與空間感知效果的影響：三種不同的360網站呈現技術(Matterport、WalkInto、Panos環耀實景)、使用者的認知風格類型與空間自我效能的程度分級。使用者體驗效果的測量方式為使用測試網站後的展覽場域學習與體驗問卷分數、網站易用性量表(SUS)、認知負荷量表，另外也進行使用者經驗訪談。本研究結果發現：使用者的認知風格分類與空間學習效果呈現顯著相關；由使用者自評的空間自我效能分級僅影響展覽場域學習與體驗問卷分數、不同的360網站技術會導致使用者對其易用性評分有差異。本研究最後綜合整理線上展覽網站的使用者經驗報告並提出改善建議，以期有助於未來使用相似技術的虛擬展覽空間設計工作。
The rapid advancement of 360-degree imaging technology and screen-based Virtual Reality (VR) has led to its widespread use in various fields involving commercial, educational, and cultural purposes. This research focuses on examining the user experience of online exhibition websites that utilize screen-based VR 360 imagery. In the study, we conducted an experiment to evaluate the effects of user experience of visiting different 360 screen VR exhibitions, particularly focusing on their perception of the exhibition space. The variables considered include three different 360 website presentation technologies provided by Matterport, WalkInto, and Panos, the cognitive styles of the test users, and the degree of their spatial self-efficacy. Our results highlight a notable correlation between users' cognitive styles and the effectiveness of spatial learning. We also find that the degree of spatial self-efficacy, as self-rated by users, impacts the scores of their learning and experience in the exhibition area. Moreover, the type of 360 displaying significantly affects the test users' assessments of usability. The insights drawn from the metrics of spatial perception of the virtual space, the user experience interviews, and the usability assessments are compiled to provide a comprehensive user experience report for online exhibition websites. We also propose recommendations for improvement, aiming to assist future design efforts in creating immersive, user-friendly virtual exhibition spaces using similar technologies.
