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 (FIO2 ) 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 FIO2 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
