Categorization of Sensory Words Based on Tactile Dimensions

Sensory evaluation of objects changes with the words for the tactile feel which are presented to subjects. However, there are few reports on the systematic collection and classification of sensory words on tactile feel. Here, we found 145 words on the tactile feel in “Word list by semantic principles” to categorize them into four tactile dimensions : hardness （hard／soft）, roughness （rough／smooth）, warmth （warm／cold） and friction （sticky／slippery, moist／dry） factors. This evaluation method can be applied sensory evaluation of the tactile feel in many fields, including cosmetics.
