| Summary: | 碩士 === 東海大學 === 工業設計學系 === 102 === A person’s preference regarding a particular product and the willingness to use it rely on the various senses of the body, primarily including the visual, auditory and tactile senses. However, most product operations and designs are based on vision and perception as their main considerations. Besides adopting tactile design for the visually impaired, there are currently many products that require such design for the general populace, for example: smartphone protective case, hand tool grip, bicycle grip, racket handgrip, etc. Most people rely on their visual sense and neglect the tactile sense, underestimating the capability of conveying feeling through tactile sensations. Instead, the focus is put on material, shape, size, etc., of the object of perception. However, surface texture not only affects comfort, but also affects its usage. Hence, through the surface texture and roughness generated by means of parametricism, this study aims to explore how different textures affect the tactile sensation of users. This study examined the degree of product surface texture and roughness; by generalizing the information collected from the literature and consultation with experts, a large number of descriptive words for tactile sensation were generated. Pertaining to users’ perception and preferences concerning tactile cognition, Rhinoceros was used to generate the different surface texture for a cognitive experiment on tactile sensation, whereby it can be used in Kansei engineering for hand phone cases to determine the relationship between product surface and the user’s degree of preference. Finally, the texture image factors affecting people can then be constructed.
