디자인 전략으로서의 촉감 연구

Shape and vision mostly have been focused for analysis in design research and making, meanwhile tactility wasn't considered seriously. Recently the study on tactility has begun. Western philosophy is used in explanation on the process from subject sense including tactility to perception and the relation between the sense including the tactility and the perception is examined by searching from Platon to Merleau-Ponty. Also, it is confirmed that the history of tactility is the history for possession by examining historical recognition change of tactility surrounding the meaning of possession, comfort, consumption, and goods. The physical stimuli of this tactility are Meissner corpuscle(Meissner's corpuscle), Merkels corpuscle(Merkel cell), Krause's corpuscle(end bulb of Krause), Ruffini corpuscle(Ruffini's corpuscle), and autonomic terminal. The physical stimulus that is perceived by these receptors' response on the stimulus is composed of 4 dimension- high-frequency vibration perception, low-frequency vibration perception, static pressure sense, and hot-cold sense. The study method of this tactility that usually measures quantitatively strength or tenacity which are the feature of material and there is the analysis of perception experiment on how human feels on tactility. Semantic Differential(SD) method, Paired comparison method, Magnitude estimation, and Free sorting task are used in quantitative subjective data acquisition methods on Texture and Materiality and subjective distance and Factor Analysis(FA) and Multi Dimensional Scaling(MDS) are mathematical process methods. It is found that tactility study in design and design product using tactility contains various possibility as a design strategy.
