Automobile driving under monotonous situations may cause the lowering of what we term a driver's activation state (AS) resulting in an increased risk of an accident. There is therefore a need to create a more suitable environment in-car so as to allow active driving, hopefully thus avoiding potentially dangerous situations. In order to develop such an activation method supported by substantive evidence of effectiveness as a final goal, the authors have firstly set out to acquire physiological variables, including cardiovascular parameters, during presentation to the driver of a screen image simulating monotonous travel of constant speed on a test-course. Subsequently, they investigated the derivation of a suitable driver's AS index. During the image presentation, a momentary electrical test stimulus of 0.5 s duration was randomly applied to the subject's shoulder to obtain physiological responses. In 11 normal subjects monitoring of physiological variables during the image presentation revealed particular patterns in the beat-by-beat changes of blood pressure in response to the electrical test stimulus. This finding, which could be explained by autonomic activity balance, suggests that the patterns may used as be an appropriate and practicable index relevant to the AS.
