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 a 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 a keyboard command.
