Creativity is indispensable for more innovative interactive system development. This tutorial is relevant to anyone involved in large projects that are exploiting new technologies or developing new interactive systems and media. The tutorial will familiarize participants with both the need for creativity, and the techniques and tools to bring this about. It will interleave short presentations with group work activities that allow participants to use different techniques for stimulating creativity. No prior knowledge of creativity models or techniques is expected. Over the last 6 years, the presenters have designed and run 14 different creativity workshops in projects developing large-scale interactive systems for major clients. Neil Maiden is Professor of Systems Engineering in the Centre for HCI Design at City University, and Sara Jones is the RCUK academic fellow in creative socio-technical system design.
