Personalised and dynamic image precompensation for computer users with ocular aberrations

Most of the computer users with ocular aberrations such as myopia, hyperopia and other high order aberrations are subject to the problems of visual blurring. Conventional methods used to counter visual blurring include spectacles and contact lenses. In this paper, we introduce an image preprocessing method that is designed to counteract the visual blurring caused by the aberration of the eye. This method processes the presented images in advance by performing personalized compensation based on the dynamic ocular aberration of the computer user. Experiments with human subjects show that the image recognition accuracy was significantly increased after the precompensation was applied. Subjective assessments from the participants confirmed the effectiveness of the method.
