Abstract
Technology developments related with brain-computer interface (BCI) promote study and research in emotion recognition. In study recognizes, classifies human emotional states, electroencephalograph (EEG) signal acquired by BCI devices will go through several process include data analysis in computational research. This article performs a survey in recent study use EEG as signal acquisition equipment, compare research targets, and provide summary of both research-grade EEG, consumer-grade EEG devices used in recent research. A comprehensive view of emotion recognition research process is given. The last section focuses on advanced processing method of extracted EEG signals proposed in recent study and compare their performances.
