Method and system for operating a display apparatus
First Claim
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.

Abstract
The invention relates to a method for operating a display apparatus (12), comprising the following steps: capture of image data from at least one part of the head of a user (14) (step 110), ascertainment of at least one parameter, which the user (14) can alter by moving at least one part of the head, from the image data captured in step a) (step 120), control of a visual representation on a display apparatus (12) on the basis of the ascertained at least one parameter (step 130), wherein the capture in step a) is taken as a basis for ascertaining at least one quality parameter (step 140) and the at least one quality parameter is taken as a basis for varying at least one resolution of at least one part of the visual representation (step 150). Moreover, the invention relates to a corresponding computer program product and to a corresponding system for operating a display apparatus.

20. A system for operating a display apparatus including:
-
a capturing device for capturing image data of at least one part of the head of a user; at least one computing device, which is adapted to ascertain at least one parameter value of at least one parameter from the image data captured by the capturing device, wherein the at least one parameter value is alterable in response to movement of at least one part of the head of the user; a control device for controlling a visual representation on a display apparatus depending on the at least one parameter ascertained by the computing device for operating an application by the user; wherein at least one computing device is provided, which is configured to ascertain at least one quality parameter based on the image data captured by the capturing device, wherein the control device is further adapted to vary 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 by the at least one computing device 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. - View Dependent Claims (21, 22)
