Should a cue be used in motor imagery scenario with csp
Posted: Sun Feb 04, 2018 6:07 pm
Hi,
I'm using the motor imagery scenario with csp. I have connected it to a game so the user can move two boxes by imagining right or left hand movements.
As I have noticed, in the 4th scenario(the online scenario) we don't need to use a cue; since when we train the LDA we give 1 second long epochs of the 4 second long training example every 1/16 second. although in the 4th scenario a Graz visualizer is used which gives the user cues .
here are my questions :
why we don't use the same "1 sec long every 1/16 sec" epochs to train the CSP filter ? instead the scenario sends the whole 4 second epoch to the CSP classifier as one training example.
Can I use the online scenario without cues or do I actually need to send cues from my game to openvibe to tell the user which direction of hand movement to think about and when?
Cheers,
Kiyarash
