cursor task results
Posted: 07 Dec 2010, 05:45
Dear all,
Thank You very much for your previous responses.
We made different trials of cursor moving task (1D/2D/3D with different number of targets), always following your tutorial step by step.
Nevertheless, we observed that in all our trials the cursor began its movement independently from the user's intention (it seemed it had a movement "by chance"). How can avoid unvoluntary cursor movements? We downloaded the latest version of BCI2000.
In all the trials we had a result such as "100% correct" and bits transferred were between 0 and 12. We observed that just hit the target once (18 trials, 1 hit, 17 invalid) and we have get automatically "100%correct", although we didn't transfer any bit. Could someone explain how the calculation is done to "% correct" and transfer bit?
We read the tutorial, but we couldn't find in it any information regarding this problems.
Hopefully, you could help us in the best way!
