In practice, most creativity techniques are still performed with traditional tools, such as pen and paper, whiteboards, and flipcharts. When transforming these techniques into a digital environment, the reduction of organizational overhead is the main goal to foster accessibility. Still, we do not know if overhead reduction fosters creativity or if it eliminates an important part of the creative process. To get a deeper understanding of these effects, we compare the performance of the creativity technique SIS (Systematic Integration of Solution Elements) in a traditional setting with a setup based on multiple interactive surfaces. By using a mix of diverse evaluation methods, we show how the use of a digital interactive creativity room can really foster creativity and produce better results.
