Abstract
Official abstract text for this publication.
A system and method of testing vision performance includes displaying a visual recognition test to a subject and receiving from the subject a response to the visual recognition test. After receiving the response to the visual recognition test, a subsequent visual recognition test is selected based on the response received from the subject, the subsequent visual recognition test is displayed, and a response is received from the subject. The subsequent visual recognition tests are repeated until a predetermined criterion is reached. A vision performance score is determined based on the visual recognition tests displayed and the set of responses received from the subject and output from the system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vision testing system, comprising: a memory storing a plurality of parameter files defining a plurality of visual recognition tests; a display operable to display an image for each of the visual recognition tests to a subject; an input device operable to receive a response to each of the visual recognition tests from the subject; a calibration sensor positioned in view of the display and configured to continually monitor one or more parameters…
