IdeaVis: a hybrid workspace and interactive visualization for paper-based collaborative sketching sessions

In this paper we describe IdeaVis, a novel approach for supporting co-located sketching sessions. Our system is based on digital pen & paper for augmenting the traditional paper-based workflows of sketching sessions. An additional focus & context visualization is used to support creative facilitators in exploring and examining the design activity, thereby increasing awareness over inhibitors that may impede the success of such sessions. The general applicability of our approach was confirmed in a user study with creative professionals. We conclude that live design activity visualizations can provide benefits for controlling typical inhibitors of creative group work without the need to change traditional workflows.
