Re: prior art?
The unique aspect to this Facebook hat is that it is permanently glued to your head and you're unable to look away from the adverts served up to the screen by Facebook. Occasionally you're allowed to send a message to friends and family to let them know that you haven't been kidnapped (but are being tortured).
The face recognition / eye-tracking system will detect and intercept any attempt to send a help message by blinking Morse code.
