Measurement and analysis of human characteristics of directional memory by electroencephalography for the brain-computer interface system

To investigate human characteristics of directional memory for the Brain-Computer Interface (BCI) system, we designed an electroencephalography (EEG) experiment in which subjects' EEG signals were measured and analyzed in several phases when directional memory tasks were presented. According to the results of our analysis of the EEG experimental data, the various EEG components followed different variations of rules in different directional memory phases (i.e., learn, maintain, and reproduce). The results indicated that the directional control of the BCI system can use different EEG signals in time and frequency domains. The results of the present study provide basic data for determining directional control of the BCI system.
