Method of detecting the increase or decrease in the power of the cursor task

[arvay]

Hi,all,

I am studying the BCI,use the curor task.
Recently using a cursor task , subjects succeeded in moving the ball .
So , there is a question in the detection method of EEG features.
I have assumed that control the ball by detecting the increase or decrease in power of a frequency band inputted to the classifier.
In that case , does it increase or decrease of the power is determined when as a reference ?

Please help.
Thanks for advance,
arvay

Arvay,

the classification happens in the cursor task, i.e., by the cursor hitting one or the other target. The cursor movement is a linear translation of the frequency power as defined by the classifier weights and the offset and gain of the adaptation.
