1. A method for operating a display apparatus, including the following steps:
a) capturing image data of at least one part of the head of a user;
b) ascertaining at least one parameter value of at least one parameter from the image data captured in step a), wherein the at least one parameter value is alterable in response to movement of at least one part of the head of the user;
c) controlling a visual representation for operating an application by the user on a display apparatus depending on the ascertained at least one parameter;
d) ascertaining at least one quality parameter based on the capture in step a); and
e) varying at least one resolution of at least one part of the visual representation depending on the at least one quality parameter;
wherein the parameter ascertained in step b) represents a measured quantity and the quality parameter represents the accuracy of measurement associated with the measured quantity or a measure of the accuracy of measurement associated with the measured quantity.
