They say one of the best ways to tell if someone is lying is to watch their eyes. Monitoring eye movements is helpful in a variety of ways. This is because what we really think and feel comes out in our eye movements, even if we don’t want to admit it or even know we are feeling it at all. Monitoring eye movements is something that a lot of people are doing for a number of reasons.
One reason people are monitoring eye movements is for lie detection, just like the old saying. This type of technology doesn’t replace current polygraph usage, but it can enhance it. Many times adding eye movement evaluation to traditional lie detection improves its reliability and clarity. Some people are using eye movement lie detection in a more entertaining way. Some new TV dating shows have learned that using lie detection software makes for an entertaining and high-rating television program. And you can even use these eye movement lie detectors in your own home!
Monitoring eye movements is helpful in other ways as well. When testing products and advertising, eye tracking can go beyond the usual evaluation methods. If a company wants to test a new soft drink, they might monitor the eye movements of the individual while they drink some of their favorite drink, then when they try the new drink. The pleasure derived from drinking something you love is a good measurement for how much you enjoy a new beverage. This can help companies tailor products to individuals in ways that other research methods cannot.
Monitoring eye movements has health benefits as well. Individuals who need extensive cognitive therapy can benefit from eye movement applications. This is because getting into the brain on a level beyond that of verbal expression can open up the past and help make corrections for the future. It is also helpful in physical health, especially when treating children.
