However, there are no research examples that evaluate and analyze tactile sensations as time series data. In this study, subjective assessment of skin lotion was carried out using the Temporal Check-All-That-Apply (TCATA) method to measure tactile sensation data of time series. We also analyzed individual differences in time series data using cluster analysis. As a result, four groups were classified from 39 participants, and each of the four clusters showed a different tendency of temporal change of tactile sensation.
