Abstract
In general, in one aspect, a graphics driver receives information related to where eyes of a user watching a video are focused, determine if the user is focusing their attention on a particular location of the video, and generates post processing instructions for pixel macro blocks of decoded video frames. The instructions are based on whether it is determined that the user is focused. The graphics driver is further to determine a focus area associated with the particular location the user is focusing their attention on, determine a peripheral area around the focus area, generate a first set of post processing instructions for pixel macro blocks within the focus area, generate a second set of post processing instructions for pixel macro blocks within the peripheral area, and generate a third set of post processing instructions for pixel macro blocks not within either area.
