Study of Maintaining Concentration by Auditory Brain Computer Interface

Recently, a new interaction technique which directly connects human brain and machine has been emerging; the Brain-Computer Interface (BCI). This paper describes auditory BCI system that dynamically responds in real time to P300 components of event-related potentials (ERP), which reflects the degree of concentration, in order to examine its sound designing potential. Based on the P300, the system feeds back appropriate sounds, warning tone or dulcet tone, to the user to maintain the degree of concentration in the aspect of sound environment design.
