Project: Interaction Techniques for Digital Tables

Digital tables allow people to interact with computer workspaces that are projected onto tabletops. Tables are interesting settings for computational work because they are common, they enable rich interaction with tools and artifacts, and they naturally support collaboration. However, digital table systems have not yet been widely adopted, and it is not clear how they should be designed to support common teamwork and taskwork patterns that are seen in tabletop activities. In this project, our goal is to gain a deeper understanding of how users' experiences can be improved when using digital table systems. We will carry out several main research activities: 1) investigate how people carry out activities on regular tables, 2) design and implement novel interaction techniques for digital tables, and 3) evaluate the interaction techniques in controlled experiments and in naturalistic settings.
