近幾年虛擬實境的議題發展快速，不少科技大廠與新創公司紛紛進駐市場，在科技蓬勃發展的情況下，虛擬實境的發展仍遇到一些瓶頸，如: 價格太高、硬體功能不足、應用軟體缺乏、無完整平台、相關硬體缺乏的問題。因此本研究之目的為探討上述問題關鍵技術的瓶頸以探索未來的技術發展機會。
由於虛擬實境的領域範圍廣泛，為了不使研究範圍跨越過多學科與技術，因此本研究藉由虛擬實境產業相關資料分析並運用質性(Quality)方法限縮領域。運用技術機會分析加入文件探勘的方法將虛擬實境的子領域「顯示互動層」以學術論文與專利比較尋求虛擬實境的技術發展機會。學術論文與專利蒐集到的有效文獻分別為1444篇與640篇。
研究結果發現硬體的發展仍是現階段的主要發展方向，而硬體設備的發展主要與顯示互動領域相關，根據虛擬實境顯示互動技術的發展，發現有三項重要的技術發展機會，分別為「觸覺與力回饋技術」、「動作捕捉技術」與「語音與手勢輸入技術」。本研究探討三項技術發展機會後，認為虛擬實境未來的技術發展將以「觸覺與力回饋」作為未來的主要發展機會。

In the recent years, the issue of virtual reality has developed quickly. Many of big technological firms continuously entry the market. In this situation, the market still meets some problems including the higher price, incomplete function of hardware, scarcity of applicative software, none of complete interface and lack of related hardware. Therefore, the target of this research is exploring key technologies of previous problems and finds out the directions for future development.
Due to the field of virtual reality is too big, research limits the field by relevant data of virtual reality and quality method. Using technology opportunity analysis to join the text mining analyze the sub-domain of virtual reality "display and interaction field", then exploring the technology development by comparing with science and patent. The effective thesis are 1444 and 640 by science thesis and patents.
The result of research shows hardware development is the main direction of development. According to virtual reality’s technological development field, finding three important opportunities: (a) tactile and force feedback technology, (b) motion capture technology, and (c) the voice and gesture technology. After discussion three development opportunities, the research consider the main development opportunity will be tactile and feedback in the recently future.
