Gabori Attack: A New Method for Testing Human Contrast Sensitivity

Abstract

The whole purpose of Gabori Attack was to develop an interesting, interactive game that would measure a person's contrast sensitivity. If it worked perfectly, it would be an improvement over the Pelli-Robson contrast sensitivity test, since it would test the user over a range of spatial frequencies instead of just one. The aim of this project was not directed primarily towards clinical use, however, but intended to produce educational tool for optometry and psychology graduate students. It would be available to those people who had little access to a machine like the CSV -1000. Still, there was a hope that the game could one day be used as a simple clinical tool to accurately measure contrast sensitivity. We wanted the game to appeal to users of all ages, but especially children (who would quickly tire of a strictly clinical vision test on the computer).
