Abstract

A noninvasive brain-computer interface (BCI)  records  brain activity from the scalp and uses the signals to  convey  lntanl
Five  users have  been  provided  with  portable  P300­  based BCI systems  that they  use  to  perform a variety  af  tasks  on a daily  basis.  Caregivers have been trained to  apply  electrode capa and start the systems.  Each  day's  data  are  electronically  transferred  to  Iha  lab. Classifica­  tion  coefficients  are updated remotely as needed. Users  are  presented  with  a matrix of Items,  each  emulataa  a keyboard  command.  The  users operate  the syslllm  by attending  to  desired malrix  item  while  all  iblms  llaah  rapidly. The attended item produces a P300 response and the unallllnded Items do  nol  The system operalBs by detec:tlng  which  Item ellclts  the  largest P300  for  a given series o f !lashes. The system selects that matrix  item,  and then  activates  keyboard  command.
