虛擬實境(Virtual Reality)的概念與技術已經提出有二十多年了，以往是被視為高科技與價格昂貴而無法親近的電腦科技。隨著資訊科技的迅速發展與網際陀路的興起，已逐漸脫下過去昂貴的面紗並且降低了相關需求軟硬體設備之門檻，所以是近來相當活躍的資訊科技。由於虛擬實境的特性與線上即時多娛體虛擬情境，使其在各領域方面都已有不錯的應用與發展，成為未來資訊科技的十大明星之一。本文首先針對虛擬實境的定義、特性與要素作探討，讓讀者對虛擬實境有一個整體的了解；接著將現有的虛擬系統做分類，不同同型態的實境之研體與軟體裝置做探討；然後對虛擬系統在不同領域的應用作介紹，最後則針對此類系統在體育與運動上的可能應用與應用實例做探討。在體育運動上，虛據實境利用其所具有的互動、擬真、融入、主動操縱等特緎，逐漸於體育教學、運動模擬訓練、運動娛樂電子遊戲、體育場館設備導覽等方面，提供資訊科技與體育運動結合的最佳範例，並塑造體育運動的在高科技下的新風貌。時值政府實施週休二日後，大力推動國人重視休閒活動與終生學習的時該，如能運用資訊科技，特別是虛擬實境於我國的體育環境與運動產業上，必能塑造出新的運動資訊產業，特別是以知識經濟為的纛的潮流下，必能打造出我國的運動知識經濟的基礎。

　　　　　The concept and techniques of Virtual Reality (VR) has been introduced to the world for more than 20 years and it was given the impression of being a high-end and expensive computer technology. As a result of the rapid development of the information technology and the Internet, both software and hardware costs had dropped enormously, the VR had become a well-known technology. The characteristic of the VR and on-line multimedia VR environment made it possible to apply in various areas. This paper starts with the introduction of definition, attribute and basic element of VR, in order to give the reader a complete understanding. The classification of the VR system and there equipment were discussed respectively. Finally, the application of VR indifferent areas as well as in the domain of sports and Physical Education were thoroughly covered. The interaction, real-like interface, immersion and active control of the VR has been used in disciplines such as PHYSICAL Education class, human movement simulation and demonstration, sports video game and virtual tour guiding system for sports arena and facilities. The tendency of a leisure-oriented society and a life-long learning age has come. It is believed that the VR technology will create a new vision for the sport and PE professionals.
