재료지각 데이터: 군집분석을 이용한 신뢰성 검정과 재료의 지각성질 분석 = Material Perception Data: Reliability Test and Perceptual Qualities Analysis of Material Classes Using Clustering Analysis

다국어 초록 (Multilingual Abstract)

Humans have the ability to perceive an object’s material and properties instantaneously, and use this information to prepare for future actions. Material perception is not only an important factor for humans but also for artificial intelligence robots that are being developed. In addition, material perception is one of the important design requirements in selecting materials suitable for the products desired by consumers and pursued by designers. Because it is impossible to perform material perception using an exact formula, it is determined from tendencies that are identified in surveys. In this study, surveys with a binary selection were conducted, presenting participants with pairs of bipolar adjectives and asking them to choose one of two.
After multiple surveys were conducted all the data were merged. Before merging the data, to ensure the reliability of the data homogeneity and correlation were tested using hierarchical clustering, correlation coefficient, and k-means cluster analysis.
Afterwards, the merged data was used to analyze universal and comparable perceptual qualities of various material classes using relative frequency and hierarchical cluster analysis.
