A design of the preference acquisition detection system using the EEG

Estimation of emotional states has been multi-disciplinary research interests. Among them, although there are many ways of the estimation such as subjective evaluations and behavioral taxonomy, direct evaluation from the human brain is more reliable. Especially, electroencephalographic (EEG) signal analysis is widely used because of its simplicity and convenience. In our research, emotional states are investigated with a simple electroencephalography which has only one electrode. This device is lighter and cheaper than existing devices. However, its feasibility has yet been proven.
