Abstract
Technologies for improving foveated rendering of an image by improving the position of the image to be displayed through image re-projection are disclosed. For example, a method may include receiving a first estimation of a predicted gaze point of a user on a display device that is determined before starting rendering a high-quality portion of the image. The method may further include causing the image to be rendered based on the first estimation of the predicted gaze point. The method may also include receiving a second estimation of the predicted gaze point. The second estimation of the predicted gaze point is determined after rendering of the high-quality portion of the image has started. Responsive to determining that the second estimation of the predicted gaze point is different from the first estimation, the method may include adjusting the rendered image based on the second estimation of the predicted gaze point and transmitting the adjusted image to the display device for display.
