The tactile perception evaluation of wood surface with different roughness and shapes: A study using galvanic skin response
By adopting the methods of PAD subjective emotion measurement and galvanic skin response physiological measurement, this study explores the differences in people’s tactile perception evaluation of the surfaces of beech materials with different roughness and shapes. The results show that females prefer beech samples with arc shapes, while males prefer the samples with rectangle shapes; participants’ emotional stability under a higher emotional arousal level can to a certain extent be maintained due to the beech materials with arc shapes. The tactile perception of males for beech materials has a greater range of emotional arousal than that of females, but the arousal speed of males’ emotions is lower than that of females’ emotions. Moreover, a better tactile perception experience can be created for participants when the roughness of beech materials is limited within a certain range of conditions, and a certain sense of “anxiousness” will be brought to participants if the surface of beech materials is too rough.
