This paper presents a novel experimental case study in which tactile sensation is analyzed as 4-dimensional subjective data consisting of stimulus, participant, evaluation term, and temporal components, using a temporal measurement approach. Specifically, the skin and lotion interaction was evaluated using the Temporal Check-All-That-Apply (TCATA) method. Two practical analysis examples were conducted to experimentally demonstrate the potential use cases of time-series subjective tactile data. In the first example, stimulus classification accuracy was compared between different sampling periods, including the whole and late periods, with the latter being akin to the conventional Semantic Differential (SD) method condition. The results indicate that the whole and early periods exhibit higher accuracy compared to the latest period, implying that temporal measurements may capture more stimulus characteristics than the conventional approach. In the second example, cluster analysis based on the time-series subjective data was conducted. The results revealed that the participants were classified into two distinct clusters, with the trends of time-series changes being significantly different between the clusters.
本文提出了一种新的实验案例研究，使用时间测量方法将触觉分析为包含刺激、参与者、评估项和时间成分的 4 维主观数据。具体来说，使用时间型“全选-应用”（TCATA）方法评估皮肤和乳液的相互作用。进行了两个实际分析示例，以实验证明时间序列主观触觉数据的潜在用例。在第一个示例中，比较了不同采样期（包括全期和后期）之间的刺激分类准确性，后期类似于传统的语义差异（SD）方法条件。结果表明，全期和早期的准确性高于最新期，这意味着时间测量可能比传统方法更能捕捉刺激特征。在第二个示例中，基于时间序列主观数据进行了聚类分析。结果表明，参与者分为两个不同的聚类，聚类之间的时间序列变化趋势存在显著差异。
