I know enough to know that using this in schools, or at work, is a human rights complaint just waiting to happen in my jurisdiction. Do people who are blind, or who have certain mental illnesses, or certain cognitive conditions, or certain conditions like paralysis, end up reported inaccurately or unfavourably by these systems? Oh, and what about ethnicity, culture, religion, race? Any bias there? Misuse of psychometric tests ("Do you make friends easily?") have resulted in payouts in the UK and Canada, probably elsewhere. This sort of emotion-detection seems analogous.
