EyeDetect is a product which measures physiological responses generated as a person reads and thinks about questions on the screen. It uses measurements of the pupils and eye tracking. The questions are usually designed to screen people for some undesirable past behaviors.  There is science showing how the technology is effective in measuring reactions in this way.

Polygraph, as its name implies, takes multiple measurements from a test subject's body while they are listening to a series of questions. Polygraph testing consists of a pre-test interview, designing questions and then recording the body's reactions. EyeDetect was designed by researchers who are experts in polygraph testing, but EyeDetect uses measurements of the eye and reading to compare reactions to the different questions of interest. 

 

EyeDetect is much quicker and in most cases less expensive than polygraph testing. A trained examiner is not required to administer the test. Almost anyone in the office can learn to administer the test in a few minutes. All testing is independently scored. The EyeDetect eliminates any "subjectivity or variability" related to using an examiner who may have biases. EyeDetect does not require any measurement instruments to be physically attached to the test subject. EyeDetect, due to its ease of use and lower cost can be moved more to the start of a screening process. EyeDetect tests exist or can be developed for English, Spanish and many other languages. 

 

EyeDetect requires some dedicated equipment, but the costs are not prohibitive. Like polygraph, both rely on physiological measurements. Most of the costs are on a per test basis, but a large user may prefer a site license. Training costs for examiners are reduced. Accuracy of the EyeDetect is similar to that for polygraph testing. EyeDetect and Polygraph test accuracy are both high, but as with all tests, not perfect. Numbers of False Positive and False Negative results will depend partly on the percentage of truthful people in the group being tested. EyeDetect is more difficult to adapt in a setting where most of the testing is for investigating specific incidents. Special question sets must be developed, checked and uploaded into the centralized test system.
