I actually read the paper and I have a question for someone who really understands this kind of research or maybe even worked in similar related research.
The paper states that one criterion for an F2F interaction to be counted is that the devices ("sociometric badges") used to collect the data must be facing each other with uninterrupted infrared line of sight.
From my experience, in an open workspace this is most of the time not needed to conduct a short F2F conversation. It's possible to quickly talk to people walking by, standing behind one's chair or sitting on the other side of the table. None of these requires an uninterrupted line of sight.
Also the device seems to have been located at chest height so a visual line of sight between eyes has not been recorded.
I wonder whether these considerations have been taken into account. The paper doesn't say anything about that.
