PROJECTS AT VISL FINISHED IN 2004
Pupil Response Lie Detector
by Gilad Frost and Raanan Sade
Supervised by Eldad Klyman
Abstract
The
original idea of this project was to create a home lie detect application.
This is of course very complicated platform, which will take long
development period. Finally, our project concentrates in one of the eye
physiological response which is the pupil diameter differences, as
response to one's guilty knowledge his pupil diameter increases. Our
application measured this change and based on GKT (guilty knowledge test)
decides if subject was guilty or innocent.

The pupil
diameter diagnose for this movie (change in percent).
Results
Conclusions
The
project results show strong correlation between the pupil diameter and
guilty knowledge.
Our application could be use (even as it is) as a part of a polygraph
machine, or after some changes as a web cam lie detect application.
Another great force of this lie detect tool is in that it can be used on a
person without his knowledge.
