Visual designer Samuel Matson has an idea on how to rid the world of gamer rage. It's not through medication, counselling or discipline. It's through prevention.
He's designed a headset called Immersion, which not only uses biometrics to track a user's heart rate, but can then adjust what's going on in a game accordingly.
Based on researching a number of gamer's heart rates while playing a shooter, and using a raw prototype hooked up to an Xbox 360, the Immersion would gently adjust the difficulty and content of a game based on how the player was feeling.
Which sounds a lot like it would only benefit singleplayer experiences, but who knows, maybe the data it captures could be useful for a multiplayer server as well.
It's exactly the kind of stuff Nintendo were thinking of with the now-dead Vitality Sensor, and at the moment it's just as real a product. But given his idea has both community and game design benefits, hopefully he can get it made!
