Design methodology is increasingly influencing Human-Computer Interaction (HCI) as well as other traditionally engineering-oriented disciplines. Unlike analytical thinking in classical engineering design processes, “design thinking” is an opportunistic, yet structured activity based on building up and combining ideas. It encourages maximum input and participation without early judgments that might lead to a fear of failure during ideation and prototyping phases. Due to an increasing need for creativity and innovation in HCI, new design methods and techniques were introduced in early process phases, which also led to a novel perspective called “Interaction Design”. One key characteristic of these methods is collaboration and embodied practice [1]. When designers are creating and revising ideas during early interaction design stages, they often harness the spatial
