AB Thispaperpresentsanelectroencephalo-graphic   (EEG)   P300-based   brain–computer   interface   (BCI)Internet   browser.   The   system   uses   the   “odd-ball”   row-colparadigm for generating the P300 evoked potentials on the scalpof  the  user,  which  are  immediately  processed  and  translatedinto  web  browser  commands.  There  were  previous  approachesfor  controlling a  BCI  web  browser.  However,  to  the  best  of  ourknowledge,  none  of  them  was  focused  on  an  assistive  context,failing  to  test  their  applications  with  a  suitable  number  of  endusers.  In  addition,  all  of  them  were  synchronous  applications,where  it  was  necessary  to  introduce  a  “read-mode”  commandin   order   to   avoid   a   continuous   command   selection.   Thus,the  aim  of  this  study  is  twofold:  1)  to  test  our  web  browserwith  a  population  of  multiple  sclerosis  (MS)  patients  in  orderto  assess  the  usefulness  of  our  proposal  to  meet  their  dailycommunication  needs;  and  2)  to  overcome  the  aforementionedlimitation  by  adding  a  threshold  that  discerns  between  controland  non-control  states,  allowing  the  user  to  calmly  read  theweb   page   without   undesirable   selections.   The   browser   wastested  with  sixteen  MS  patients  and  five  healthy  volunteers.Both  quantitative  and  qualitative  metrics  were  obtained.  MSparticipants  reached  an  average  accuracy  of  84.14%,  whereas95.75%  was  achieved  by  control  subjects.  Results  show  thatMS   patients   can   successfully   control   the   BCI   web   browser,improving their personal autonomy
