It feels like there are far too few controls on this study for anything other than "more research is required" conclusions. Notably: 1. Did fatigued and non-fatigued users participate in the same style of camera display? Were they held in presentation, face to face, or "Brady Bunch" mode? Did users have self-view on, shrunk, or off? 2. Of the 100ish participants selected, where is the control group who received no guidance on when to turn cameras on or off? Do they have a similar variation in fatigue between genders and weeks? 3. It seems odd that the gender variance in fatigue was selected for review and the managerial / employee division was not. Given that 45% of the sample was supervisory this would have been a useful element to understand. One would normally expect that supervisors will be less fatigued by video camera use as it may be their policy, or they may have more experience.
