E3: Iwata shows Wii Vitality Sensor
Aims to relax rather than excite.
Mario's legal guardian Satoru Iwata has introduced a curious pulse-measuring device known as Wii Vitality during Nintendo's E3 press conference.
Looking for all the world like one of those machines we have on Brighton pier which tells you if you're in love by sticking your finger in it, the device is designed to go beyond a simple cardio report.
In fact, in a rather poetic description, Iwata promised that it would provide information "relating to the inner world of your body". Although probably not in a particularly medical sense.
Instead, it's aimed at aiding relaxation by monitoring stress and nervousness, even helping people to sleep.
No software was announced, but expect Mario Police Polygraph to be hitting the shelves soon.
