our control paradigm was steady state visually evoked responses -- these are low-frequency components of a scalp EEG rig that correspond to the visual cortex locking on to a blinking test pattern. On a good day with a bald subject and fresh gel, decoding time is between 6 and 11 seconds. A tobii eye tracker has a latency of about 30 ms. Spatial discrimination is oodles better, too.
