A method for enhancing digital information displayed to computer users with visual refractive errors via spatial and spectral based processing
Pages 22 - 25
Abstract
The ability to interact effectively with computers through typical graphic user interfaces (GUIs) is greatly affected by any refractive errors present in an individual's visual system. These errors can be mathematically modeled (as the wavefront aberration function) and a system for overcoming these aberrations is proposed which has the potential to increase the effective human-computer interaction for these individuals. This paper introduces a dissertation research plan that seeks to:1. further develop techniques realizing software pre-compensation2. test this method using human subjects with each subject's unique wavefront aberration.
