Supporting Effective Interaction with Tabletop Groupware
Current computing systems are primarily designed for a single person working alone at a PC, with support for enabling remote collaboration over a network. However, traditional work practices involve not only individual work and communication with remote colleagues, but also face-to-face group meetings and activities. This latter class of interactions remains largely unsupported by computing technology. In this talk, I will focus on one particular means of computer support for face-to-face group work: interactive tables. Interactive tables are computer-augmented tables that support simultaneous inputs from a group of co-located users. This emerging class of devices presents interesting challenges for user interface design. In this talk, I will discuss several challenges in designing applications for interactive tables, covering issues such as the orientation of information, widget layouts, appropriate input mechanisms, integrating personal content, multi-user coordination, and the impact of tabletop UIs on group dynamics. I will present implementations and evaluations of prototype tabletop systems that address these challenges.
