| Summary: | 碩士 === 國立臺北科技大學 === 互動設計系碩士班（碩士在職專班） === 105 === When watching a 360° video through a VR headset, the viewer is free to browse the surrounding scene, and the image is no longer present in a single direction as usual. Although panorama photography enriches the possibility of multimedia composition, it also breeds new problems of its own. The viewers are easy to lose their orientation in the stereo scene because there is no any restriction when browsing. They might also miss the important message or scene because of the same reason. This study builds an interactive guiding interface in VR scene to explore whether this interface is helpful for viewing VR videos. In this study, we observed the behavior of subjects via the ‘Think Aloud protocol’, and recorded the experimental detail. After that, we interviewed the subjects and analyzed the data. The overall conclusions of this study are as follows. 1) Verified the guiding interface does have the effect of prompt, and it meets viewers’ expectation of usability of user interface. 2) The viewers expected the interface to be more naturally present in the scene when they were watching a virtual reality video. The results of this study can be used as a basis for the study of the interactive guiding interface design in virtual reality environment.
