Nintendo announces the Wii Vitality Sensor, a device that attaches to the tip of the player's finger that measures their vital signs and helps them relax.
It sounds like one of those biorhythm reading machines you find in dirty bowling alley arcades, though as a Nintendo Wii product it is of course pristine and white. The device was presented by Nintendo President Satoru Iwata at the company's 2009 E3 press conference, following a brief speech about the difficulty of video games. Without actually tying things together, he explained that the new device lets you see the information relating to the "inner world" of your body in order to achieve greater relaxation. The device attaches to the bottom of the Wii remote and then clips onto your finger.
It sounds like it could be used to measure stress levels via pulse rates, with the data then used to adjust game difficulty. That, or Nintendo just wants to see if we will pay them money to let us pinch our fingers.
Iwata presented the device and then left, making no mention of when it would arrive, how it would arrive, or even if it would arrive. Good old Nintendo-branded strangeness.
