Immersive Kansei Engineering : A New Method and its Potentials

Product development becomes more and more complex. Products obtain more and more functions and at the same time they must be still attractive for the customers to ensure a successful product launch. To predict their acceptance and to gain knowledge on how to design attractive products new methods are developed in the field of the emotional design. Such a method is the Kansei Engineering, which collects the customers hidden subjective needs and their translation into concrete products. We present and validate a new form of the Kansei Engineering method for emotional assessment by the customers during the product development, based on an interactive product experience in Virtual Reality. The major novelty of our kind of method is the use of immersive representations which focuses on both, the product itself and its environmental context, too. Customers experience these virtual representations quite dynamically and with this freely describe their emotional influence on them. We come to the conclusion that more reliable emotional customer feedback can be acquired through the implementation of the proposed context paradigm shift. The fusion of product and environmental context enables the simultaneous role of the customer as a subject (actor) and an object (observer) in the virtual world, thus promoting reliable emotional reactions. Despite of some disadvantages, we propose Immersive Kansei Engineering as a reliable method for emotional product assessment by the customer
