surely you would have more to say about this Quaternion. how did it feel like?
I never said I actually used the headset or that they even let people touch their prototype.
However, as the article states, the headset detects emotions, excitement, tension, facial expressions and a few cognitive actions.
1. Use your emotions, as well as your excitement and tension levels to drive the in game music and/or adjust the game's difficulty level. This data was being displayed on screen at last year's demo. When someone in the audience decided to sneak up on the guy wearing the headset and startle him while he had his back to us, his tension meter spiked big time.
2. Have your in-game avatar mimic your emotional state, facial expression, blinks, eye orientation. This was all functional when I saw it demoed a year ago.
3. Detect cognitive actions to trigger certain actions in games. For example, using force powers in Jedi Academy: You control the game exactly the same way as before, but if you want to use the force, you can simply think about it instead.
It seemed to work really well.
It's not the be all and end all of gaming, but I think it definitely opens new doors for developers, not to mention the cool factor and immersion of being able to trigger powers with your mind and have your avatar mimic you.
