Copenhagen.
The first main session at the COST298 conference is on interdisciplinary design, and begins with a presentation by James Stewart and Laurence Claeys. They ask how speculative research for innovation can be conducted within interdisciplinary frameworks. Problem here include that different disciplines work within very different time scales (e.g. rapid prototyping vs. long-term observation of users), that they use different mental models, and that disciplines tend to under-value one another and misuse one another's research approaches.
