摘要:The focus of this paper is interaction design research aimed at supporting interaction design practice. The main argument is that this kind of interaction design research has not (always) been successful, and that the reason for this is that it has not been guided by a sufficient understanding of the nature of design practice. Based on a comparison between the notion of complexity in science and in design, it is argued that science is not the best place to look for approaches and methods on how to approach design complexity. Instead, the case is made that any attempt by interaction design research to produce outcomes aimed at supporting design practice must be grounded in a fundamental understanding of the nature of design practice. Such an understanding can be developed into a well-grounded and rich set of rigorous and disciplined design methods and techniques, appropriate to the needs and desires of practicing designers.
