Nintendo president Satoru Iwata has unveiled the Wii Vitality Sensor at the company’s E3 press conference.
The peripheral goes over the end of a finger and detects the user's pulse. Iwata said that while Wii Fit lets you see the balance of your outer body, the Vitality Sensor gives you info on your inner balance.
Iwata said that games are traditionally associated with stimulation, but that it might not be long before they “could be made for people to unwind or even fall asleep."
It’s unclear about how the peripheral will feature in games as no compatible software was demoed.
In a press release the platform holder said: "Nintendo’s newest groundbreaking product, the Wii Vitality Sensor, expands the appeal of video games. It will initially sense the 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."
