Saul is a Professor in the Department of Computer Science at the University of Calgary. While he is a computer scientist by training, the work by Saul and his students typify the cross-discipline aspects of HCI and CSCW. He and his team are well known for their development of toolkits enabling rapid prototyping of groupware and physical user interfaces (e.g. Groupkit, Collabrary, SDGToolkit, Phidgets); innovative and seminal system designs based on observations of social phenomenon (e.g. GroupSketch, GroupDraw, TeamRooms, Notification Collage); articulation of design-oriented social science theories (e.g. awareness, casual interaction and privacy), and refinement of evaluation methods (e.g. heuristic evaluation of groupware). He is also known for his strong commitment in making his tools, systems, and educational material readily available to other HCI researchers and educators. His HCI lecture notes were one of the first to be available on line, and are heavily downloaded and used.
