We proposed vir`tual concert experience systems in which visual effects appears depending on a user’s brainwaves or heartbeats. The proposed system is composed of a simple EEG recorder, a smart watch measuring heartrate, a tablet terminal, a server and a 3D game engine on a computer, and an immersive head mounted display. We implemented the proposed systems, conducted experiments, and took a questionnaire on subjects. The results showed that generating visual effects by increase of beta/alpha ratios of brainwaves enhances the subjects’ concentration and the subjects felt correspondence between their excitation and appearance of the visual effect when the system utilizes brainwaves. The results also showed that subjects felt fun in watching the concert with both the system utilizing brainwaves and system utilizing heartbeats.
