Abstract: Technologies and techniques for combating drowsiness of a driver of a motor vehicle. A calculation rule is used in which a fatigue progression curve, that represents a fatigue development of the driver over time, can be generated based on a parameter set, and specific values for the parameter set are determined for a route ahead. The fatigue progression curve for the route ahead may be determined via the calculation rule using the determined values for the parameter set, and the fatigue progression curve is analyzed. A countermeasure may be initiated depending on a result of the analysis, in which countermeasure at least one value of a variable parameter of the parameter set is specifically changed.

Abstract: A method for avoiding a field of view disturbance for an operator of an object. The field of view disturbance IS caused by the overlay of virtual additional information via a display unit of a transportation vehicle or data glasses. The overlay of additional information supports the operator in the operation of an object. The method carries out an image analysis by which it is checked whether a field of view disturbance is caused by the overlay of the virtual additional information, and a measure for suppressing the field of view disturbance is carried out when a field of view disturbance is detected.
