[0071] overview
[0072] There are many applications that involve the user and images where the user is gazing at different areas of the screen in succession. Examples include video games, virtual reality scenes, video streaming, and augmented reality projections.
[0073] When looking at the screen, the user's eyes are sensitive to higher resolution in the area of the screen surrounding the gaze point. The fixation point is aligned with the fovea, the area of the retina that provides the highest visual acuity and has the highest concentration of cones. In regions of the retina beyond the fovea, sensitivity to resolution decreases, and visual acuity decreases the further away from the fovea. In the parafovea (an annular region in the eye that bounds the fovea), the eye is still sensitive to resolution, but to a lesser extent than in the fovea. In regions outside the parafovea, the eye is significantly less sensitive to differences in resolution.
