Nintendo recently announced their going to focus on health applications using non-wearable devices in the near future. Sadly this is all they were willing to say at this point in time and so it’s pretty much anyone’s guess what their actually working on. While Nintendo has developed successful exergames with the likes of the Wii-Fit their entry into more physiologically driven gaming for health applications never really got off the drawing board. As such I’d hazard a guess that their working on a camera based heart monitor similar to the one supported by the new Xbox Kinect for use in the Wii-Fit U.
