That (above) was Nintendo President Satoru Iwata at last year’s E3. Cool idea, eh? So what happened to it?

The device — a pulse reader that fit on a fingertip and aided/monitored one’s ability to relax, I guess — was the kicker of the Wii-maker’s showcase a year ago, and it was only fair to expect that this year there would be some blossoming of the plan. But at this year’s event we got nothing. Many blogs noticed its absence. Read here, here, and here.

In essence, Iwata said Vitality Sensor lives. However, a fireworks show is no place to demonstrate a state-of-the-art pillow, and that Nintendo is searching for the right pillow show. Or something like that.

So here is the answer straight from Iwata (through an interpreter), in a response to an analyst’s query about the lack of ground-breaking ideas from Nintendo at E3 2010:

What we have shown and announced here at e3 has shifted more toward the traditional gamer and traditional Nintendo audience. Perhaps we have not talked about some of these other elements and games that perhaps you are interested in talking about. While we haven’t focused on these elements here at the show, the question is what is the appropriate timing and the appropriate venue for sharing some of those ideas with a broader audience.
