No, I am not basically asking for that whatsoever. Automated emotion detection is NOT a solved problem (there are no services that reliably deliver prediction across untrained data sets), and the case of the elderly is clearly a case that would also need to be solved. As an implementation note, I intuit that most of emotions could probably detected from the eyes, so the gravity-induced droop isn't necessarily problematic. And no, don't go assume that I am biased against people with no eyes. What the hell...
