Quite a few years ago (5 or 6 I think) I saw an interview with a researcher who thought that bio-feedback was the next wave in gaming because the game could determine whether the player was actually interested in what they were doing and make adjustments ... I've never seen it tried on a large scale, and I'm not sure if a person's pulse and temperature are enough information to determine their interest, but I am interested to see how Nintendo intends on using this.
