Abstract

We investigated the possibility of realizing an analog-like control driven by SSVEPs elicited by just two LEDs flickering at different frequencies. Eight subjects participated in the study during which they had to gaze upon one among 7 locations on a 30 cm horizontal virtual line. A linear model that was able to predict the correct viewed position with a mean error of about 2cm by analyzing 4 seconds of data was built. This suggests that analog-like controls can be implemented in BCIs.
