P300 Based Brain Computer Interfaces:An Overview

Brain computer interface is a direct communication way between the brain and a computer or external devices. BCI can translate user brain activity into corresponding commands for communication with or without using conventional communication. The P300 is an event related potentials which evoked the process of decision making. Here the P300 signals are elicited from the EEG [2] and then further procedure are going to be processed. In this paper, we review the different techniques which are used in the different applications of P300 based BCI system and compare how the P300 is efficient than the other conventional BCIs.
