US CapitolUnfortunately, you don’t have to look far for examples of national security concerns. From terrorist attacks to mass shootings, our country has more reasons than ever to be worried about threats against its citizens.


However, some of the most innovative companies and minds are hard at work to address the challenge of national security. Eye tracking technology is one method for keeping our country safer – here are three reasons why:


1. Deception Detection – How many people do you know that give away a visual clue with their eyes when telling a lie? We speak with our body movement more than we know and tracking the eye movement of suspects during questioning. Research has shown that when people are lying their pupils may become dilated or follow repetitive patterns. Using eye tracking technology can provide security officials with more advanced options for efficiently and effectively completing their duties.


2. Aiding Those on Watch – Let’s face it – humans make mistakes and even those people ensuring our security are still human. We can all suffer from a lack of sleep or other types of distractions. Unfortunately, when it comes to homeland security, this becomes an immense security risk. Eye tracking technology can aid people in this industry, helping to limit operator error by tracking their drowsiness or other various inhibitors.


3. Sight on Flight – Since 9/11, safety in the air has been a top priority. Increased scanning and security measures have grown by leaps and bounds. Eye tracking could take it a step further. New kiosks with the ability to assess people through various bodily cues are being considered as a part of the boarding process. Eye tracking could be implemented in these kiosks and if a person’s cues set off any red flags, law enforcement could be immediately notified to begin taking necessary preventative measures.


We are fortunate to live in a place where we can generally live our lives without consistently concerning ourselves with security, but it is still something that needs plenty of attention. As technology continues to move forward, our nation’s security should certainly benefit from these advances.
