臭味的定义是一种滋润程度适中的质地；然而，许多人在触摸含有少量液体的干燥固体材料时会感受到“臭味”。这里，对12种材料的粪便感觉进行了评估。我们发现，粉末的粪感得分最高。多元回归分析表明，粪感是一种复杂的湿润和柔滑的感觉。我们分析了物理特性和湿润/光滑感觉之间的关系，以显示受试者同时感觉到某种感觉。湿润光滑的手感与材料的表面粗糙度和摩擦特性有关。当手指开始在材料表面上移动时，以及当手指移动并摩擦材料表面时，分别可以感受到湿润和光滑的感觉。
Shittorifeel is defined as a texture that is moderately moisturized; however, many people experience ‘shittorifeel’ when they touch a dry solid material containing little liquid. Here,shittorifeel was evaluated for 12 materials. We found that the highest score ofshittorifeel was achieved by powders. Multiple regression analysis showed thatshittorifeel is a complex sense of moist and smooth feels. We analysed the relationship between the physical properties and the moist/smooth feels to show how subjects felt certain feels simultaneously. The moist and smooth feels are related to the surface roughness and friction characteristics of the materials. The moist and smooth feels can be perceived when the finger starts to move on the material surface and when the finger moves and rubs the material surface, respectively.
