PaperSketch – A Paper-Digital Collaborative Remote Sketching Tool

Pen and paper support the rapid production of sketches. However, the paper interface is not always optimal for collaborative sketching as seen in brainstorming sessions where multiple parties would often like to communicate and participate in the sketching synchronously. Novel interactive paper solutions may provide the answer by bridging the paper-digital divide and allowing users to sketch on paper simultaneously while capturing the actions digitally. We present an analysis of collaborative sketching activities in working environments with remote participation. After highlighting the importance of paper for natural interaction in these settings, we introduce PaperSketch, an interactive paper-digital tool for collaborative remote sketching. We discuss the collaborative development of ideas based on the prototype and outline how important feedback issues have been addressed by utilising spatial constraints and multimodal features.
