Event-related potential (ERP) is bioelectrical activity that occurs in the brain response to specific events or stimuli, reflecting electrophysiological changes during cognitive processes. ERP important neuroscience and has been applied brain-computer interfaces (BCIs). However, because signals collected on scalp are weak, mixed with spontaneous electroencephalogram (EEG) signals, their tempora...

Abstract This paper addresses the development of a dementia screening tool using character-input-type brain–computer Interface (BCI). A blinking letter board is presented to subject for each matrix by BCI, and keeping an eye on one character, character-gazing estimated based event-related potential P300 subject. In this experiment, instructed specify subsequently watch task character. Four sets...
