Abstract
Embodiments of the present invention relate to a replicator that reproduces acuity deficiencies for use during an accessibility verification procedure. The replicator applies in real time at least one filter to an original video feed. Each filter includes a programmable definition to mimic a type of visual acuity limitation, such as color blindness, myopia, hyperopia, astigmatism or reduced contrast. Prior to and/or during the accessibility verification procedure, a tester is able to select one or more filters to be applied to the original video feed to thereby produce a filtered video feed. The filtered video feed is shown on a display and portrays what an individual with corresponding visual disorder(s) sees. The replicator can be updated to add, delete or modify one or more definitions.
