ABSTRACT: In this paper, we present the development and evaluation of a custom on-screen image precompensation algorithm designed to match the visual capabilities of each user, to allow efficient access to images displayed on the screen of the computer. The method uses the characterization of the optical system in the eye of the computer user, which is obtained through a Wavefront Analyzer, to modify the display images in a way that will counter the distortion that they will experience in the eye of the user. An empirical evaluation, involving 20 subjects with varying degrees of visual dysfunction confirmed that the method used for precompensation provides a significant increase in retinal image quality for users that have some visual aberration present in the optical systems of their eyes. The methodology presented here represents a step forward in the direction of adaptable computer interfaces, which may represent the future in customization of human-computer interactions.
