An examination on operation methods of AR multi-viewpoint viewing system for Ohayashi

Japan is rich in cultural properties of great historical and artistic value, of which the most important are protected as nationally designated cultural properties. Intangible cultural properties are techniques that have been handed down from generation to generation, such as theater, music, and craft techniques. In Japan, where the population is aging rapidly, digital archiving is essential for the transmission of intangible cultural assets. In this study, we focused on the musical accompaniment of the Kanuma Imamiya Shrine Festival (Kanuma Autumn Festival), which is designated as a UNESCO Intangible Cultural Heritage and a nationally designated Important Intangible Folk Cultural Property. Although the Kanuma Autumn Festival had to be canceled last year due to the emergency declaration requested by the spread of coronavirus infection, the festival is still being carried on. In this study, we have developed multi-viewpoint viewing system for ohayashi content with the cooperation of the Kamifukatsu Music Preservation Society and evaluated the system through experiments with participants. As a result, we obtained positive feedback from the participants, while those who had experience with musical performances pointed out points that needed to be improved. The controller was used as a method of interaction with the contents, but other methods have not yet been compared. Therefore, we aim to support the inheritance of tradition and examine the most user-friendly interaction method in terms of operability.
