Vitality sensor is nothing like motion control

I also don't think it's going to change gaming but i can see a couple of possible aps.

The game could just calculate your resting heart rate before you start playing in much the same way Wii Fit uses your BMI as a starting point. Resting heart rate is generally positively correlated with age and negative correlated with cardiovascular fitness and could serve as a basis for the game to measure and track your "vitality".

It could be used in a yoga or some other relaxation based game where lowering of your heart rate below your normal resting or pre-excitation rate could be used to reinforce the benefits of relaxation.

In horror games it could being implemented something like the sanity effects in Eternal Darkness, with your iheart rate having an effect on your perception of what's happening in the game or even the control or difficulty of the game. Simple conditioning would mean that sequences that frighten you (increase your heart rate) and adversely affect your ability to play would get easier to complete on subsequent play-throughs as you become accustomed to the frightening stimuli. In essence you learn to master your fears. It could be used in games like Trauma Centre to similar effect

The question of course remains how consistent and predictable such changes in heart rate are and whether or not they can be succesfully integrated into gameplay.
