How about vision based emotion recognition of viewers with cameras in the televisions and monitors? Sure sounds creepy and behaving different when observed etc.

How about vision based emotion recognition of viewers with cameras in the televisions and monitors? Sure sounds creepy and behaving different when observed etc. But I believe people will forget they are "observed" so the effect dimishs after a time. Than we would have a quite honest emotional feedback for movies. Even for specific scenes, for advertisment, etc
