Pervasive Computing

Common graphical user interfaces (GUIs) do not support co-located collaborative interactions very well. Novel approaches like tangible user interfaces [1], interactive walls, and tabletop systems [2] meet the users' needs in group interaction situations much better. Good computer support allows face-to-face interaction, offers large surfaces, involves body movements, includes real objects and is smoothly integrated into the users' environment. Especially in learning contexts, many of these affordances can lead to much better tools, supporting kids' activity, fostering creativity, and enabling group communication. In this paper, we discuss our experience in three application domains for the design of novel co-located collaborative learning interfaces: playful learning interfaces for kids, shareable domestic applications and creative work tools. Our current research focuses on the specific requirements of these different applications areas in order to enhance playful, shareable and creative interactions. In each of these domains, we have developed prototypes to support and afford collaborative and creative learning and working environments.
