You’re quite right. NIRS itself isn’t slow, but blood response in the brain is (e.g. the several second lag from neuronal activity to increase blood flow). As NIRS measures blood saturation, all in all, the technology as a whole is too slow to give an online reflection of cognitive activity.

I wouldn’t say that NIRS is slow. It’s measured at 10 Hz and if blood flow is holding up response you can measure the decrease in deoxyhemoglobin, which is fairly instantaneous.

I’ve been writing on these devices and other novel input devices on my blog, Myomancy for a while.
My main interest is in how these devices could be used in education. Neuro-feedback devices are the obvious options but the evidence on their effectiveness is not strong.
I’m excited about other technologies such as how simple head tracking [ http://www.myomancy.com/2008/03/wii-head-tracking ] could be used to teach posture and balance skills. Or how the iPhone’s technology could change education [ http://www.myomancy.com/2008/02/how-the-iphone-will-change-education ].
For pure tech-porn, check out these Foldable Interactive Displays [ http://www.myomancy.com/2008/03/more-future-training-technology ]. Nothing to do with brains or education but an exciting bit of technology.
