1. A method for avoiding a field-of-view disturbance for an operator of a transportation vehicle, the method comprising:
superposing virtual additional information, via a display unit, into a field of view of the operator of the transportation vehicle;
performing image analysis relative to the field of view of the operator to detect whether the superposition of the virtual additional information causes disturbance to the field of view of the operator including obscuration of at least one object in the real environment as a field-of-view disturbance, wherein image analysis is performed to check whether the superposition causes an obscuration of regions in the field of view of the operator, and, in the check relating to obscuration of regions in the field of view, analyzing three successive images, wherein for the first image, the filling degree of the total image is determined, for the second image, the filling degrees of a first number of image segments of identical size are determined collectively less than the total image, and, for the third image, the filling degrees of a second number of image segments of identical size are determined collectively less than the total image and greater than the first number of image segments; and
preventing the field-of-view disturbance by altering the superposition of virtual additional information in response to the field-of-view disturbance being detected.
