> an F2F interaction was recorded when three conditions were met: two or more badges (i) were facing each other (with uninterrupted infrared line-of-sight), (ii) detected alternating speaking, and (iii) were within 10 m of each other.
Condition (i) seems like it'd result in a lot of false negatives in various situations common in open-office environments, e.g. two people talking to each other without actually leaving their desks (especially if they're across from each other, since that'd mean there's likely at least one screen in the way).
