Kansei Engineering aims to develop such a product that people want to have deeply in their mind. The term of â€śkanseiâ€ť implies psychological feeling and needs in mind. Before purchase of a passenger car; every one imagines in mind of â€śpowerful engineâ€ť; â€śeasy operationâ€ť; â€śbeautiful and premium exterior; â€ścool and relaxed interiorâ€ť and son. These words express the kansei; and the consumers willingly want to have such a kind of vehicle; if the manufacturer realizes a vehicle just fit to their imagination. However; it is regret that we have not ever had such science and technology as to treat technologically psychological feeling and needs (kansei).
The kansei engineering is able to grasp the consumersâ€™ kansei; to analyze the kansei using statistical methods; and to transfer the analyzed data to the design domain. Nagamachi founded the kansei engineering around in 1970 in Hiroshima as a customer-oriented product development. He has engaged in the development of the kansei engineering for over 35 years and developed a lot of the kansei products and the kansei engineering methods (Nagamachi; 1974; 1989; 1995; 1996; 1998; 2002: 2005)
