Abstract
A subject's eye movement and pupil diameter are measured while the subject is exposed to visual stimuli. The apparatus and method utilizes an eye-look detector to determine a subject's visual examination of a presented image and by computer recording an analysis superimposes icons representing the lookpoints over the image. The apparatus and method are not only of value in running routine tests but also may be used for new experiments.
Claims20
An apparatus for testing the eye response of a subject to test stimuli comprising:
- a presentation device for presenting an image to a subject as a test stimuli;
- an eye-look detector for detecting a series of lookpoints of the parts of said image being viewed by said subject;
- and
- a computer including a storage device for recording said lookpoints and a program having a means for determining said lookpoints, a means for correlating said lookpoints to locations on said image, and a means for superimposing said lookpoints on said image for review.
A method for testing the eye response of a subject to test stimuli comprising the following steps:
- displaying to the subject an image as a test stimuli;
- determining by an eyelook detector a series of lookpoints of where said subject is looking on said image;
- recording said series of lookpoints in a computer storage device;
- and
- superimposing said series of lookpoints onto said image after the test.
