. He introduced vision-realistic rendering to simulate human vision based on ocular measurements of an individual. Using these measurements, synthetics images are generated. This process modifies input images to simulate the appearance of the scene for the individual. That work led to an investigation with Fu-Chung Huang of how to display images to compensate for the specific optical aberrations of the viewer, resulting in vision-correcting displays. Given the measurements of the optical aberrations of a user’s eye, a vision correcting display produces a transformed image that when viewed by this individual will appear in sharp focus. This could impact computer monitors, laptops, tablets, and mobile phones. Vision correction could be provided in some cases where eyeglasses are ineffective. This research was selected by ''
