12.1: Invited Paper: An Overview of Vision Realistic Rendering and Vision Correcting Displays

Abstract

Vision-realistic rendering is the computer generation of synthetic images that incorporate the characteristics of a par-ticular individual's entire optical system. Specifically, we simulate the scanned foveal image from wavefront data of actual human subjects.The concept of a vision correcting display involves digitally modifying the content of a display using measurements of the optical aberrations of the viewer's eye so that the display can be seen in sharp focus by the user without requiring the use of eyeglasses or contact lenses. Given the measurements of the optical aberrations of a user's eye, a vision correcting display will present a transformed image that when viewed by this individual will appear in sharp focus. Vision correction could be provided in some cases where spectacles are ineffective.
