The technology, when packaged into a smartphone, for example, can be used to help some of those with Asperger’s syndrome to read facial expressions. But it can also be used in a videotelephony app as a surreptitious “lie detector.” It could be a great tool during remote diagnosis and counseling in the hands of trained professionals. But it could also be used to record, analyze and track people’s emotional state in public venues: in front of advertising panels, as well as courtrooms or even job interviews. It can help overloaded elementary school teachers better decipher the emotional state of at-risk children. But it can also lead focus-group obsessed movie studios to further mechanize character and plot development.
The GPU in our computers is the ideal matrix-vector processing tool to decode facial expressions in real-time in the very near future. It would be highly conceivable, for instance, for a presidential candidate to be peering into his teleprompter to see a rolling score of a million viewers’ reactions, passively recorded and decoded in real-time, allowing him to modulate his speech in synchronicity with that real time feedback. Would that be truly “representative” democracy or abdication of leadership?
