In promoting disaster prevention education, it is desirable to produce and provide high-quality educational materials. Important issues include making the educational materials easier to understand and reducing the psychological hurdles that viewers have when viewing the educational materials. Noda and Matsuoka (2024) produced disaster prevention videos using 3DCG animation and 2D pictogram animation, and compared the effects of watching them once and repeatedly. As a result, viewers rated 2D as easier to understand than 3D, and viewing once was more favorable than viewing repeatedly. In addition, the results of the psychological image measurement using the Semantic Differential (SD) method suggested that 3D may be a greater psychological burden than 2D. More detailed consideration is needed on how viewers perceive these differences between 2D/3D and the difference in the number of viewings. Therefore, in this study, we apply Multidimensional Scaling (MDS) to the SD data of Noda and Matsuoka (2024) to examine the effects of the 2D/3D difference in disaster prevention videos and the difference between whether or not they are repeatedly presented on the perception of the video viewers.
