Semantically Layered Structure of Tactile Textures

Specification of Individuality in Causal Relationships among Texture-related Attributes, Emotions, and Preferences

“…Chen et al [6] suggested that this layer encompasses two sublayers, which is also consistent with the report of Nagano et al [8], and indicates the complexity of human affective perception. The top, or preferential, layer indicates personal preferences about the item.…”

“…Experiences pertaining to touch are sometimes categorized into semantically different layers [6][7][8], as shown in Fig. 1.…”

“…Chen et al [6] Figure 1: Semantically layered structures of touch-related adjective dyads. The words in each layer were selected from the literature [6][7][8]. The structure of the lower level layer varies less across people, whereas that of the higher layer is more dependent on individual perceptions.…”

“…mapped discrete layers of sensory and affective adjectives used to describe textures, based on correlations among the scores assigned to the adjectives in a sensory evaluation experiment. Nagano et al [8] developed a method to establish the semantically layered model of psychophysical, affective, and preferential adjectives, on the basis of impact relationships among the words. Guest et al [7] and Ackerley et al [11] projected textures into both psychophysical and emotional spaces, with each space being described by at least three individual dimensions.…”

“…As found in these studies, the perceptions and feelings caused by touching materials depend on individuals. In principle, the layered structures of texture-related experiences should also exhibit individual differences; however, the explicit establishment of such structures has begun only recently [6,8], so individuality in the structure has yet to be reported thus far.…”
