A design support system based on uncertain evaluation process in KanseiOne of the major problems in designing interactive systems is that users do not perceive a designed system as designers intended. For example, designers have constructed a system in an effort to embody a set of given top-level design concept, such as heavy and deep and simple. However, users might conceive the designed system as sober and practical. Designers want to identify the design elements that cause the mismatching, and replace them with the ones that might reduce the degree of mismatching. This paper proposes a cognitive model, a dual mapping model, that simulates uncertain evaluation process in kansei by designers and users. There are two mapping processes in the model: the designers' mapping process that transforms a set of top-level design concept onto a system sketch, and the users' mapping process that converts the design sketch to impression words. Based on the dual mapping model, this paper proposes a tool for designers that supports their activities for tuning a design sketch so that users impressions to it should converge to the given top-level design concept. We show an on-going prototype that partly implements the tool proposed in this paper.
