Approaches to create artifacts taking kansei into consideration are multiple and are shared among various disciplines, such as kansei engineering, kansei science, and kansei design. In this paper, I focus on the discipline of kansei design and show that various approaches exist within this discipline. These can be characterized based on their focus: either the physical or the interactive materiality of the artifact. Indirect kansei design, mostly focusing on the physical materiality, is based on indirect (or mediated) perception theories. It often relies on representations, models, and metaphors to provide meaningful input to the design. Direct kansei design, mostly focusing on the interactive materiality, is based on direct (or ecological) perception theories. It mainly relies on the designerly attitude of the designer in the process, and apprehend design meaning to emerge from the reflection upon design exploration within the process. Describing and differentiating these two approaches show how kansei is considered differently by different approaches of kansei deign, looking forward a dialogue between these approaches in order to obtain a greater insight on kansei and on its consideration for designing.
