Abstract
In the design of product texture, it is important for a designer to grasp the difference of user's affective characteristics between single-modal sensations and multi-modal one. Customers' emotional responses may differ depending on visual, touch and their combination. In this paper, we propose an evaluation framework to visualize the difference of kansei structure towards product texture between different modalities. In the method, we apply the simultaneous relationship analysis and ISM (Interpretive Structure Model) to structure words for evaluating texture's kansei. The framework considers actions for evaluating touch i.e. haptics and affordances towards texture. To demonstrate the effectiveness of the framework, we conducted a sensory evaluation experiment using plastic texture samples and cylindrical shapes having different textures as case studies.
