This
paper
presents
an
electroencephalo-
graphic (EEG) P300-based brain–computer interface (BCI)
Internet browser. The system uses the “odd-ball” row-col
paradigm for generating the P300 evoked potentials on the scalp
of the user, which are immediately processed and translated
into web browser commands. There were previous approaches
for controlling a BCI web browser. However, to the best of our
knowledge, none of them was focused on an assistive context,
failing to test their applications with a suitable number of end
users. In addition, all of them were synchronous applications,
where it was necessary to introduce a “read-mode” command
in order to avoid a continuous command selection. Thus,
the aim of this study is twofold: 1) to test our web browser
with a population of multiple sclerosis (MS) patients in order
to assess the usefulness of our proposal to meet their daily
communication needs; and 2) to overcome the aforementioned
limitation by adding a threshold that discerns between control
and non-control states, allowing the user to calmly read the
web page without undesirable selections. The browser was
tested with sixteen MS patients and five healthy volunteers.
Both quantitative and qualitative metrics were obtained. MS
participants reached an average accuracy of 84.14%, whereas
95.75% was achieved by control subjects. Results show that
MS patients can successfully control the BCI web browser,
improving their personal autonomy
