Hierarchical Model of “Feeling of Luxury:” Genuine and Artificial Leather Case Study

In this study, we used the physical properties of leather as a case study to quantify the “feeling of luxury” perceived by humans using a hierarchical model. We constructed our model with a physical property layer, an impression layer, and feelings layer. The physical property layer contains physical leather properties obtained from image measurement experiments. The experiments conducted multi-angle measurement because the appearance of leather changes depending on the observation angle. As described above, the remaining two layers include subjective scores obtained by subjective evaluation experiments. In particular, we determined the words used in the impression layer by an impression evaluation experiment in which we extracted the representative impressions perceived from leather. As a result, we were able to quantify the “feeling of luxury” perceived by the participants from leather by a simple estimation equation with two extracted representative impressions.
