…And Straight Up Is Right Out

In my computer supported collaborative work seminar, we were discussing the design of table-top systems for synchronous collocated collaboration. There was a bit of conversation on the problems and strategies with images projected onto the table (e.g., people getting in the way of the beam). There seemed to be consensus that most simple and effective solution was projectors mounted directly above the table.

I pointed out that, in this context, straight down was the most straightforward.
