Attention / Relaxation

[NickDevoctomy]

Hi there,

Please forgive the stupid question, but I'm back to playing about with this SDK again and have the live feed sample running great. I'm just trying to understand what's being displayed,

So we have 5 graphs, top 2 being raw output from AF7 & AF8 and next 2 being raw output from TP9 & TP10. These correspond to standard probe positions on the head. All good.

Now the next graph, I understand that displays an FFT of AF8 and an FFT of TP9 on the same graph, this essentially shows the frequencies on those channels for a slice of time. I suck at maths and that's my understanding at least.

So do those 2 FFT plots relate to Attention & Relaxation? Or Do those have to be calculated by looking analysing the results of both of those?

Thanks for any help, it's difficult finding this information on Google without going down a rabbit of science papers which I simply don't understand.
