Abstract

Lowering of what we term a driver\´s activation state (AS) during monotonous driving conditions may increase the risk of an accident. To develop an in-car environment that allows active driving - "biofeedforward system" - we have investigated the effects of applying a stimulus of increased inspired oxygen fraction (F_IO₂) supply on a driver\´s AS, using simulated monotonous driving. We used our previously substantiated index of AS derived from beat-by-beat blood pressure (BP) response following an electrical stimulus. We have made physiological measurements including BP and found that the increased F_IO₂ stimulus is effective in enhancing the AS. This finding was also confirmed in terms of the autonomic activity balance as well as the lengthening in time for active, safer, driving
