Pushing the Communication Speed Limit of a Noninvasive BCI Speller [article]

Po T. Wang, Christine E. King, An H. Do, Zoran Nenadic
2013 arXiv   pre-print
Here, we report on the development of a novel noninvasive BCI communication system that achieves ITRs that are severalfold higher than those previously reported with similar systems.  ...  These results provide compelling evidence that the ITR limit of noninvasive BCIs has not yet been reached and that further investigation into this matter is both justified and necessary.  ...  One of the most robust EEG-based BCI communication systems is the P300 speller, developed originally by Farwell and Donchin [10] .  ...

For instance, for a P300 based speller, we would give priority to speed and choose values that yield a small response time, at the cost of the higher false alarm rate.  ...  The orientation of each wheel is controlled by the computer, however the rotation speed of the wheels is free: the scooter is set into motion by pushing it, hence it is a passive device.  ...  A.2 Time independent equations To derive the control variable, we express the equations of motion with respect to the new variables η = t 0 |ṡ| dτ instead of the time-index t.  ...
