Engaging Virtual Interactions Based on HMD and Dual Controllers: Taking Virtual Dunhuang Cave As An Example

為了保存許多歷史遺產，許多遺蹟文物都進行了數位化的保存。透過這些資料，我們建立了一個i-m-Cave平台，讓使用者在許多設備上都可以使用， 本篇論文以虛擬實境搭配頭戴式顯示器為主軸， 讓在保護文物的同時， 使用者依然可以一窺歷史的景觀，並且與之互動。我們以莫高窟61窟為例， 在虛擬世界中增加入許多多媒體的元素，希望透過這些新穎的媒介， 增進使用者體驗。另外我們設計了關於虛實穿梭以及虛擬探索的方法， 期望使用者可以透過Semi-room可以更流暢地進入虛擬石窟，並且在石窟中，可以藉由三種移動方式Walk，Jump-and-Glide和Portal進行虛擬探索， 透過實驗評估成果，且收集使用者回饋。第一個實驗，我們發現多數使用者認為Semi-room可以有更多的緩衝時間做心理準備，有助於增進進入虛擬世界的體驗。第二個實驗，Portal是最受使用者喜愛的移動方式，可以短時間進行有效率的大範圍移動，並且減少暈眩的可能。第三個實驗，對受測者而言，塑像3D復原是個非常新奇的體驗，透過文物的立體化從更多的方向觀察細節。最後我們將這些結果應用在我們的系統，期待可以帶給使用者創新的體驗。In order to preserve the historical heritage, many cultural relics have been digitized to save. With these data, we have established a i-m-Cave platform for users can be used on many devices. In this paper, we focus on a virtual reality for the head-mounted display. While protecting cultural relics, users can still interact with the history of the landscape. Taking Mogao Cave 61 for example, we add number of multimedia elements in the virtual cave. Through these novel elements, we hope can enhance user experience. In addition, we designed the methods of the virtual transistion and virtual exploration. Expect users can be more smoothly to go into the virtual caves by Semi-room and move by Walk, Jump-and-Glide and Portal. We analysis the results of studys and collect users feedback. The first experiment, we found that the most users think they can have more time to do preparation by Semi-room. It is helpful to enhance the experience. The second experiment, Portal is the most appreciate move method. It can do wide range movement effectively in the short time and reduce the possibility of dizziness. The third experiment, the statue 3D restoration is a very novel experience for users. From the different direction to observe the three-dimensional artworks can discover more detail. Finally, we apply these results in our system, we can look forward to bringing innovative user experience
