Emotion Detecting Tech???

Ok I know what your thinking and yes strangely enough this is video game related. Siliconera reports (courtesy of Joystiq) that Sony has filed a patent for a technology that uses a camera and microphone to detect a player's emotional state, including laughter, joy, anger, sadness, and boredom. 

This new tech. will read metadata retrieved from a camera and microphone to know your emotional response to what you're seeing which means yes the Playstation 3 will know when your giving it that evil glare for you being upset over a game. 

Also according to the filing, this technology identifies emotions by reading facial expressions of group behavior as well such as two players congratulating each other. 

Applications of this tech. is still unknown at this time so it's really hard to place a use on this technology, we don't even know if it will be used at all by Sony. The level of research and development of the tech. is also shady, but for better or worst I am looking forward to seeing how this play out.
