Being in Public and Reciprocity: Design for Portholes and User Reference.
Andreas Girgensohn, Alison Lee, Thea Turner · International Conference on Human-Computer Interaction · 1999
We found that Portholes users want to know about being in public, who can see them (audience) and who is looking at them (lookback). We developed one 2D and two 3D theatre layouts of the display and different amounts of audience information to address these concerns. Different layout sections display core and non-core team members and lookback information. A survey of and a preferences experiment with 28 first-time users revealed two key results. First, there was a strong preference against the use of blue rectangles for audience information but preferences were varied on the amount of detail. Second, layout preferences matter but were varied.
