Toward a P300-based Computer Interface

This article describes research into the use of the P300 event-related potential (ERP) as a control signal in a computer interface for locked-in patients. The aim is to have the P300 ERP control a screen cursor. EEG scalp electrode signals were measured in subjects who were presented with a target-detection task on a computer screen. Variables such as target on-time, ISI, null target inclusion, and trial averaging were manipulated and the results are discussed in terms of rate vs accuracy. Graphs illustrate the results.
