Real-time simulation of arbitrary visual fields

ABSTRACT

This report describes an algorithm and software for creating and displaying, in real time, arbitrary variable resolution displays, contingent on the direction of gaze. The software produces precise, artifact-free video at high frame rates in either 8-bit gray scale or 24-bit color. The software is demonstrated by simulating the visual fields of normal individuals and low-vision patients.
