Motion Controls arentnew Nintendo simply took this and made it affordable and got creative same with the Wii Vitality, existing tech but using it for new ideas.

Tehehehe

Oh really?  What gaming company has used this technology before?

It doesn't just measure pulse.  It also measures the electric conductivity of your fingertip.  So it's closer to a polygraph test.

I highly doubt any games will require a Wii remote, a nunchuck, a Motion+, and a vitality sensor.  The Wii comes with a nunchuck, and Wii Sports Resort has sold over 12 million copies, so that's over 12 million Motion+'s out there.  Pretty big head start.

Electronic scales and strain gauges existed for many decades before Wii Fit. It doesn't really matter if the technology is new. How it's applied can be innovate no matter how old the underlying technology is.

The vitality sensor component could be under a couple dollars, maybe even a few cents. It's probably just a led light with a light sensor. I don't see how that could possibly add up to hundreds of dollars.

I agree, though it's probably because Nintendo is more likely to get it right again with the Vitality Sensor, whereas Natal and the Arc, at least for now, aren't going to have as big of an impact.

Standard pulseox found in any hospital. There are even disposable versions available.

Wii Vitality sensor

Notice that little hole in the bottom? That's probably the light sensor.

The Vitality Sensor is a joke right now. Have to see how they use it before we can tell if it's the next Wii Fit or the next Wii Music.

I agree with the last sentence!!!!

I expect to see it before natal and Arc is released, they will show a few games for it then release them bundled with vitality sensor in the next 3 weeks, possibly!
