Abstract

A method and a device for driver state evaluation are provided. In a detection step, in a sensor-aided manner, a driver's viewing direction in a field of view defined relative to the vehicle is detected and a solid angle oriented to the viewing direction is determined depending on at least one parameter that influences the field of view. In an evaluation step, at least one object point of the three-dimensional surroundings of the driver is evaluated on the basis of the latter's position with respect to the solid angle determined and an attentiveness-related driver state is ascertained depending on this evaluation and is output.
