What started out as small idea in the Computer Science Lab at the University of Arizona has evolved into a great solution which detects if you lie to it by tracking about 50 different measurements at the same time. The system is called AVATAR which stands for Automated Virtual Agent Truth Assessment in Real Time.
Check out the links below to see the system in action and learn more about the implementation of the EyeTech Digital Systems VT3, eye-tracking technology, along with many other sensors from other manufacturers.
