Single display groupware: a model for co-present collaboration

We introduce a model for supporting collaborative work betweenpeople that are physically close to each other. We call this modelSingle Display Groupware (SDG). In this paper, we describe themodel, comparing it to more traditional remote collaboration, Wedescribe the requirements that SDG places on computer technology,and our understanding of the benefits and costs of SDG systems.Finally, we describe a prototype SDG system that we built and theresults of a usability test we ran with 60 elementary schoolchildren.
