Customer expectations for automotive design are increasingly rising, which plays an important role in purchasing behavior. Among them, automobile interior materials are one of the factors that have a significant influence on the overall luxuriousness and satisfaction of automobiles. One of the main affective responses to automotive interior materials is a tactile sensation, and since it is complexly constructed, systematic modeling is required. The current research proposed and tested a structural equation model (SEM) that describes hypothesized relationships among affective variables affecting tactile satisfaction such as luxury, soft, slippery, smooth, bumpy, and thick. A total of 26 samples including natural and synthetic leather using interior material in an automobile was selected as a stimulus to recruit 53 participants. All affective variables were found to affect luxuriousness that subsequently affected tactile satisfaction (path coefficient = 0.652). In particular, perceived softness was a dominant factor affecting tactile luxuriousness in leather (path coefficient = 0.305). The findings of the present study have significant implications for both theory and practice on affective responses and levels that affect tactile satisfaction in leather using automobile interior.

客户对汽车设计的期望越来越高，这在购买行为中起着重要作用。其中，汽车内饰材料是影响汽车整体豪华性和满意度的重要因素之一。对汽车内饰材料的主要情感反应之一是触觉，由于其构造复杂，因此需要系统建模。当前的研究提出并测试了一种结构方程模型 (SEM)，该模型描述了影响触觉满意度的情感变量之间的假设关系，例如奢华、柔软、光滑、光滑、颠簸和厚实。包括使用汽车内饰材料的天然皮革和合成皮革在内的总共 26 个样品被选为刺激物，招募了 53 名参与者。发现所有情感变量都会影响奢侈品，进而影响触觉满意度（路径系数 = 0.652）。特别是，感知柔软度是影响皮革触觉奢华度的主要因素（路径系数 = 0.305）。本研究的结果对影响使用汽车内饰的皮革的触觉满意度的情感反应和水平的理论和实践都具有重要意义。
