Abstract
P300-based brain-computer interface (BCI) has been widely studied over two decades. However, there are several factors that hamper P300-based BCI to be used in daily life. EEG acquisition devices are often too much expensive for an average customer. Although the Emotiv Epoc headset is a kind of low-cost device for recording brain signals and has been adopted to develop some BCI systems, due to the limited number of electrodes, the Emotiv Epoc headset cannot cover the regions of scalp that are convenient for detecting P300, so the effectiveness of the Emotiv Epoc headset used in the P300-based BCI has been doubted by many researchers. This paper aims to examine the performance of Emotiv Epoc headset used in the P300-based BCI system. Six participants participated in the experiment and two paradigms were compared. The results demonstrated that P300 could be effectively detected from the brain signals recorded by the Emotiv Epoc headset, showing the promising future to develop low-cost P300-based BCI systems.
