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.
