虛擬實境被認為是影響人們生活的重要傳播科技，但其應用會受到人因、成本以及內容短缺等問題而限制，不但實務領域缺乏完整清楚的設計指引、學術界也持續發現新的VR人機互動問題與解決方式。為了以務實、有系統的方式探討虛擬實境合適的應用，本研究透過VR應用現況、文獻整理、使用性測試、使用者報告等探索性研究，歸納出以虛擬實境作為複雜空間預覽學習的可能有發展價值，並針對這樣的應用脈絡設定幾個可預知的使用性問題，進而設計三個實驗。實驗一探討使用頭戴顯示器以及用桌機螢幕，以及不同的地標導航設計，是否對空間知識攫取表現以及所採取的策略有所影響；實驗二探討不同擬真程度的場景虛擬實境再現方式，對於提高尋路表現、降低尋路焦慮是否有影響；實驗三探討不同的敘事或互動策略向使用者介紹複雜立體空間的習得效果。三個實驗的實驗刺激均會以Unity製作可在HTC vive上運作的可互動虛擬空間，使用者的反應則會使用眼動儀、生理回饋儀、認知地圖評估、尋路績效測量、空間能力自評標準問卷等方式來進行科學化的評估。本計畫預期完成後可對虛擬實境之空間設計方式以及設計預覽或預走系統時具體有用的設計指引。
Virtual reality is as an important communication technology with certainlimitations such human factors, high costs and content shortage. Inorder to explore the practical application of virtual reality in apragmatic and systematic manner, the current study proposes an promisingapplication of virtual reality as a learning interface for acquiring thespatial knowledge of the complex space. Through exploratory studiesincluding literature review, quantification meta-analysis, interviewingVR industries, and collecting VR user report, some predictableusability-related problems have been emerged. Therefore we come of ofthree experiments to investigate several factors. Experiment 1 examineswhether the use of a head mounted display and a desktop screen affectsthe performance of spatial knowledge acquisition and the way findingstrategy. Experiment 2 uses different degree of visual fidelity of aindoor environment design, and examines the effect of visual fidelity inway finding performance and way finders' anxiety. Experiment 3 proposesdifferent manner of pr-exposure (preview)of a complicated large spacesuch Taipei main station and examine which way leads to the best wayfinding results. All of the experiment stimuli are designed in Unity anddisplayed and operated on the HTC Vive, and the participants responsesare collected by eye movement and physiological metrics. Participants'performance are evaluated with cognitive map producing and performancemeasurement. So far, the research has completed the setting ofexperimental environment. We also completed partial data collection anda preliminary experiment. The research presume the results of the studywill benefit the practical design of VR space by providing spatialdesign guidelines.
