DEVICE AND METHOD FOR MODIFYING RENDERING BASED ON VIEWER FOCUS AREA FROM EYE TRACKING

摘要

Devices and methods for modifying content rendered on the display of a computing device as a function of eye focus area include receiving sensor data from one or more eye tracking sensors, determining an eye focus area on the display screen as a function of the sensor data, and adjusting one or more visual characteristics of the rendered content as a function of the eye focus area. Perceived quality of the rendered content may be improved by improving the visual characteristics of the content displayed within the eye focus area. Rendering efficiency may be improved by degrading the visual characteristics of the content displayed outside of the eye focus area. Adjustable visual characteristics include the level of detail used to render the content, the color saturation or brightness of the content, and rendering effects such as anti-aliasing, shading, anisotropic filtering, focusing, blurring, lighting, and/or shadowing.
