Preferred Aspect Ratio of Panels with a Traditional Design Pattern of Cypress Bark Roofing

In recent years, many traditional techniques that have been handed down from generation to generation have been declining, and the question is how to carry on traditional culture. In response, the Hiwadabuki (cypress bark roofing), a traditional roofing technique in Japan, was utilized to develop the Hiwadabuki patterned panel, a panel with a traditional design pattern of Hiwadabuki. The purpose of this study was to clarify the appropriate shape of the Hiwadabuki patterned panel when used as an art panel. Experiments were conducted to compare the preference for Hiwadabuki patterned panels with different aspect ratios and monochrome panels of cypress bark color with different aspect ratios. The results showed that aspect ratios of 1.618 (horizontal) and 1.414 (horizontal) tended to be the most preferred, and similar results were obtained for the monochromatic panels. On the other hand, cluster analysis indicated the existence of several groups with different preferred aspect ratios.
