Studying collaborative surface use to guide large display interaction design

In this poster, we focus on the use of large vertical surfaces (e.g. walls, flipcharts, whiteboards), articulating four unique roles they play in collaboration: presentation, ideation, reference, and notice. By understanding these roles, we can design interaction techniques that exploit people's expectations and uses of these surfaces. As an example, we realize one design idea in Pick-and-Point—a fluid interaction technique that moves content from personal surfaces onto large surfaces that recognizes the collaborative role of large vertical surfaces.
