I just thought about it.
Nintendo said it was a biometric sensor rather than just an ordinary heartbeat monitoring device.
When I pay horror\fast paced action games I don't get scared or nervous because this is typical of me not getting immersed by games, it's like "Yeah I'm playing a random amount of polygons", I'm texting other people by phone, pausing the game to see what's going on TV and maybe stop gaming if something interesting - Conen O'brien - is on tv and so on. I don't get that immersed in a game... well at least I don't notice it.
Now imagine the Vitality Sensor is as sensitive as a Polygraph.
It would recognize even the slightest change in your vital signals to know if we are nervous without us even knowing we are. Nintendo said it was a biometric device! Why not? This is perfect for horror games!
Now imagine another game like "Wii Lie".
One player would ask questions just like a polygraph technician, and the player connected to the Vitality Sensor would just say YES or NO, or choosing it on screen via wii remote pointer (or the "technician player" would choose so the interrogated player didn't have to move).
Soccer Mom asking the 8 year old kid connected to the Vitalaity Sensor:
EDIT:
"Did you eat trash food today?"
"did you brush your teeth this morning?"
"have you behaved Well at school?
Imagine the possibilities of this! You'll have a domestic polygraph in your house!
Zelda Wii Support example:
Random Enemy on field asks: "Do you want to kill me?"
If you DO want - not what you choose on screen, but what do you FEEL about the game and what your conscious wants you to do - it would define if a battle would start in the case of a YES (want to kill), or if the enemy gives you some rare item in the case of a NO (don't want to kill).
You would have no control over your choices because is not a matter if you want to manipulate the game or not, is what do you FEEL about it.
This can be applied in various forms like: "you're enjoying the game?"; "is it to hard for you?"; "Do I look stupid?"; every answer twisting the plot of the game!
YES?
