Abstract

2-dimensional movement control is an interesting issue in Brain-Computer Interface. In this paper, we present a motor imagery based 2-D cursor control paradigm. To move the cursor to a random position, two-class motor imagery is simultaneously combined to output 2-D command, which directly points to target position. A center-out experiment (8 targets) is set to verify the proposed paradigm. The results of the online experiment (three subjects participated) validate the proposed strategy very well.
