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 materialswith different roughness and shapes. The results show that females prefer beech samples with arc shapes, while males prefer thesamples with rectangle shapes; participants' emotional stability under a higher emotional arousal level can to a certain extentbe 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 theroughness of beech materials is limited within a certain range of conditions, and acertain sense of "anxiousness" will be brought to participants if the surface of beech materials is too rough.
