Will the Wii Vitality every reach 99% of all customers?

At a recent investor conference, Nintendo was rumoured to of stated that the reason the Wii Vitality has not been released was because it only works for 80% of players and before they release it they want it to work for 99%. If this issue concerns the physiological game mechanic (i.e. only 80% of players can control their physiology according to the requirements of the game mechanic), then the product will be on hold for a very long time.

Note: For the purposes of this post I’m going to assume Nintendo are experimenting with a heartbeat (HR) rate based biofeedback relaxation game which they’ve alluded to previously at E3 2009. However what I’m going to say applies equally to all physiological game mechanics I know of and should be borne in mind when developing your own physiological game.

Most people I know who work in the field of physiological computing purchase off-the-shelf sensors for their research. There’s nothing specifically wrong with this, most of us are not engineers and nor do we have the time to become one as our interests lie elsewhere. At LJMU all our equipment is off-the-shelf and we have some damn fine devices which we’ve used in our work (e.g. see my review of the BM CS-5 cheststrap). However I’ve noticed we place a lot of faith (and money) in these devices to do what they say on the tin (e.g. see the issue I raised last year about the software bundled with BioHarness). Personally I like to know the limitations of any equipment I’m using, and if I find anything outside the spec I’ll try to figure out why (sometimes to my detriment as you’ll see below). Its not that I’m particularly troubled if a sensor has any defects as I don’t expect them to be perfect, the problem I have is with defects I don’t know about as they can make things, problematic to say the least. For example the first off-the-shelf sensor I ever worked with was the WaveRider Pro a 4 channel biofeedback device which had a slight problem with counting time.
