As a basic approach to realization of the real-time image generation that reflectsects physiological and psychological state, in this study, an auditory biofeedback system mediated by the cross-correlation coefficient ρmax from blood pressure to heart rate has been developed. First, a personal computer system that can calculate ρmax in real time has been developed. Next, a feedback loop has been added to the system so that the magnitude of a noisy sound presented to the subject can be changed according to ρmax. The results obtained from the experiments using this system indicated that the auditory biofeedback loop mediated by ρmax can be realized. However, the fine tuning of the controller in consideration of individual difference is required for establishing a sufficiently stable feedback.
