Analysis of Sensory Impression Factor Structures of Jomon Potteries through a Semantic Differential Method Viewing 3D Models on MR equipment

As Jomon pottery, particularly flame-like pot, is increasingly perceived as a form of artistic expression rather than merely archaeological artefacts by museum visitors, it is of interest to study the sensory impressions associated with it, and to investigate commonalities with the spatial cognitions that modern people have of Jomon pottery. A sensory impression test was conducted using 3D hologram models of pottery on Microsoft HoloLens with 73 participants, who rated 16 sensory adjectives through the Semantic Differential Method and also made free selections of impressive parts of the pottery. Factor analyses and analyses of variance were performed on these adjective groups, and identified main factors were "vigor," "attractiveness," "surface smoothness," and "lightness." The Okinohara and Umataka types consistently showed significantly higher scores on "vigor" (the first factor) and "attractiveness" (the second factor.) The correspondence of these two typological groups in sensory impressions and spatial cognitions suggests a shared commonality between them.
