Currently, researches of EEG signals are studied in the various areas such as medical science, neuron science, psychology, computer science, electric engineering. With the increased interest in the neurofeedback and brain-computer interface area in recent years, diverse studies are being actively conducted. In this paper, we developed a brainwave measurement system to confirm a person’s degree of depression and degree of concentration. The system, through data quantification and graphs, can diagnose the user’s mental state and degree of concentration in real time, and can be used to develop therapy programs for various nervous and mental disorders and to monitor improvements in learning/cognition.
