Like any self-learning sentient world-destroying super-computer, PS3 just wants to understand human emotion. One of the crazier patents discovered by Siliconera reveals Sony's plans to put a real emotion engine into the PS3. The example above highlights the system's ability to detect laughter, but that wouldn't be all the PS3 would be able to feel. The patent notes other emotions: sadness, excitement, anger, joy, interest, and boredom.

We're not entirely sure the gaming applications of a system like this (and clearly, neither does Nintendo). We can hypothesize a few scenarios. Perhaps if a game detects boredom, it can increase the number of enemies on screen. If it detects anger, the difficulty can go down. And finally, if it detects sadness, it'll tell you to just please stop playing Lair.
