Identifying the visual interference by design and tactile properties of leathers using automobile interior

This study investigates the difference in tactile sensory response when touching leathers under tactile-only and visuo-tactile environment. Total of 7 tactile variables for leathers were selected and utilized to investigate whether they derive significantly different tactile response by existence of visual interaction. As a result, affective variables of `rugged', `elastic', and `thick' showed significant difference in response by varying context. Besides, the level of design variables also led the difference in tactile-only and visuo-tactile response. Increment in level of emboss spacing and young's modulus led larger difference between the two contexts, and thickness made difference in its all levels. Overall, it is possible to grasp the influence of visual interaction when evaluating the leathers for automobile interior, and verify the difference made by changes in design variables.
