Hi all
I wanna build a ciruit for brain to control Walkman speaker volume (by
the busy level of logical thinking, more logical thinking, smaller
volume, vice versa)
I tried EEG b4, but it's not user-friendly (need gel).
So i changed the approach to use near-infrared red (NIR)
http://www.acad.polyu.edu.hk/~02471629d/nir.pdf to capture the status
of brain.
It has features of noninvasive, no interferece with EMG, ECG, and the
most important, no need gel.
What i wanna ask is that:
1. Is it really possible to measeare busy level of logical thinking by
just using NIR ?
2. If it's possible, what position of NIR should i place ? (for hand
movement imagination, it should be put on C3 of 10-20 EEG system, how
about logical thinking ? on the frontal side ?)
3. Any substitute of Hamamatsu C5460-01 (NIR sensor) and 700nm/800nm
LED (NIR emmitter). I found that it's quite difficult to buy them in
Hong Kong. Also, i suspect they are expensive. Any other cheaper
substitutes ?
Thank very much for help.
