10. Smart glasses for augmented display of information objects, the smart glasses comprising:
a display surface, which is configured to display an information object in an augmented manner;
a smart glasses camera, which is configured to acquire a camera image having at least one marker or at least one object; and
a control unit, which is configured:
to mask the camera image using a masking area and to evaluate the masked camera image by using a computer-assisted pattern recognition method in order to locate the at least one marker or the at least one object;
to ascertain a smart glasses pose by inside-out tracking in dependence on at least one of a position, a size, or an alignment in dependence on the at least one marker or the at least one object in the masked camera image, wherein the camera image is only taken into consideration outside the masking area for the pattern recognition method; and
to output the information object on the display surface in dependence on the smart glasses pose.
