Collaborative design and its evaluation through Kansei engineering approach

Abstract

This paper presents a proposal to reconstruct some specific towns which were attacked and destroyed by Huge Tsunami, for example, in Tohoku region of Japan on the 11th of March, 2011. A collaborative approach has been employed to provide some trial proposal to reconstruct such damaged towns by means of Internet Community as follows. (1) Providing a proposal and pictures to reconstruct, especially offering visual design concept of living space for slope topography through social network system as an example of Internet Community; (2) consulting and discussing the above proposal and pictures among specific Internet Community with analysis by Kansei engineering; and (3) improving an original proposal into more efficient and flexible one. Suitable methods for adjustment are sometimes necessary to avoid occurrence of conflicts from many requests. Kansei Engineering may consolidate several kinds of requests, translate their expressions into set of numerical values(namely vectorize) and reduce conflicts of request into stable adjustment (namely, "not drastic" reformation). The paper explains in detail the above approach for practical collaboration for design of Living Space for Slope Topography and adjustment scheme by means of Kansei engineering approach. It also mentions some senario to brush up the proposal by means of the above collaborative approach and some problems to be resolved to make it more fruitful.
