Eye tracking system looks deep into your eyes - can tell if you’re lying

SMI RED-oem Remote Eye Tracking platform render. (via SMI)


Law enforcement and federal agencies have been using polygraph machines to detect lies since Cesare Lombroso introduced his blood pressure device back in 1895. Before that? Torture was used as the best method to detect fibs (still is to some extent). Just ask any witch that was present at the Salem Trials and they could probably tell it didn’t work that well. Some analysts will tell you that the eyes are the gateway in detecting if someone is telling the truth or not. They claim the rate a person blinks is a telltale sign of lying as well as not making eye contact or even looking up and to the left or right may be an indication of false pretenses. Some of the early pioneers of computerized polygraph have banded together to form a company, known as Converus, which is developing a new platform that tracks eye movement to detect deception.


The soon-to-be-released EyeDetect device is outfitted with German-based SMI’s (SensoMotoric Instruments) RED-oem Eye Tracking 3D camera system that tracks gaze, eye movement and pupil dilation down to 1/10 of a millimeter. According to Converus, lying causes minute changes in the eye’s behavior because it induces ‘cognitive load’ (psychology- load related to executive control of working memory), which has an effect on eye movement. Think of it like computer RAM that holds on to pieces of data before being replaced by different programs. EyeDetect captures that ocular data and analyses it to assess the ‘likelihood’ of deception while ‘suspects’ answer a series of true or false questions. The company claims the system has an accuracy rate of 85%, which is pretty high in terms of reliability but most courts in the US still don’t allow polygraph tests submitted as evidence. Converus is set to launch their device in April of this year, with Mexico as its first test subject. Businesses will use it for pre-employment screening as well as using it for random testing on employees to weed-out those individuals that accept bribes or are involved in other nefarious activities (there goes police officers and government officials).

    I'm glad your experience was not negative.

    this is a fallacy, I just have nothing i wish to share.

    The polygraph is used because it does provide a baseline of lying or not.  It is very effective against the average person and it helps take the decision out of the domain of a an educated guess.

     

    I have taken the test and all I can say is that it was no big deal and it gave me access to toys beyond my wildest dreams.

    Unless you have something to hide, you should not worry about taking the test.

    If you have something to hide, then it is better that you stay away from the jobs that require trust.

     

    The decision is yours, but by refusing the test, you automatically cast doubt about your character.

    Many consider your refusal as an admission of untrustworthiness.

     

    I have know some people who have refused and they limited their career because they were automatically unqualified for some of the more challenging and interesting projects.

     

    Just a thought.

        kind of like how locks only keep the honest people, honest.

    I feel the same way.

    I would pick nothing, these test can do nothing that an observant interviewer can't figure out on their own, countermeasures aside.

     

    I can understand why a polygraph is used in criminal investigations, I can't however understand why people would subject themselves to one for any job.

    For most people, just knowing they will be randomly selected for a Poly is enough reason to keep clean.

    If someone is going to do something bad, then the Poly does not work unless you catch them while they are doing something bad.

     

    The current US laws prevent former employers from providing "accurate information" about past employees, so a Poly is much better for accuracy.

    Open ended questions are useless for determining hiring.  I mostly judged people on attitude after they demonstrated technical knowledge.

    If I was not sure of a person, I just did not hire them.  The whole process is about risk management.  No process is 100%, but there a little things that indicate the persons intent.

     

    You do not have to like them, but short of any other accurate method for determining truth, they are better than nothing.

    Information control is essential in keeping track of who knows what and when.  Most people show signs of behavior before they do bad things, but you still need to know what to look for and when to suspect things.  Those talents are not common and we need more people who are good at it.
