Nintendo announced today that it was adding the Wii Vitality Sensor to the list of things one can attach to the Wii Remote. Nintendo's official announcement claims it will expand the appeal of video games.

How? Well, we're not quite sure yet, as we've not yet poked the Wii Vitality Sensor. But these beautifully unblemished, wrinkle-redacted hands have. Initially, Nintendo says, it will sense a user's pulse and "a number of other signals being transmitted by their bodies, and will then provide information to the users about the body's inner world."

Yes, it's all vague "life rhythm" non-scientific stuff, but this are Nintendo games here. They're not claiming to cure cancer or helping you prevent a heart attack. At the very least, it could make horror games more interesting.
