Abstract
A display assembly displays a virtual object in a select location wherein an eye viewing the virtual object has an expected gaze direction. Deformation of the display assembly is detected. The deformation causes the virtual object to be viewable in an altered location wherein the eye has altered gaze direction. The virtual object may be displayed in a corrected location wherein the eye viewing the virtual object in the correct location has a corrected gaze direction that is moved closer to the expected gaze direction than the altered gaze direction.
Claims17
A viewing device for displaying rendered content comprising:
- a display assembly that includes an optical display configured to display a virtual object in a select location on the display assembly, wherein an eye viewing the virtual object has an expected gaze direction;
- and
- a deformation detection system connected to the display assembly and including an eye tracking camera configured to capture light reflected from the eye;
- and
- a gaze angle calculation module configured to calculate a measured gaze direction of the eye viewing the virtual object on the display assembly based on the light captured by the eye tracking camera, the measured gaze direction being an altered gaze direction due to deformation of at least the eye tracking camera, and calculate a deformation of the eye tracking camera of the display assembly based on the measured gaze direction being an altered gaze direction that is different from the expected gaze direction.
A method of displaying rendered content comprising:
- displaying, with an optical display of a display assembly, a virtual object in a select location on the display assembly wherein an eye viewing the virtual object has an expected gaze direction;
- detecting, with an eye tracking camera configured to capture light reflected from the eye, a deformation of the display assembly, wherein the deformation causes the virtual object to be viewable in an altered location wherein the eye has an altered gaze direction;
- and
- calculating, with a gaze angle calculation module, a measured gaze direction of the eye viewing the virtual object on the display assembly based on the light captured by the eye tracking camera, the measured gaze direction being the altered gaze direction due to deformation of at least the eye tracking camera;
- and
- calculating a deformation of the eye tracking camera of display assembly based on the measured gaze direction being the altered gaze direction that is different from the expected gaze direction.
