Utilizing Eye-Tracking Technology as an Intelligence Gathering Tool
Jeffrey Gainer ProudfootOctober 13, 2010Readings in MIS
Problem: Screening agents lack the ability, and technology, to identify persons with knowledge of, or familiarity with, wanted persons.
Literature ReviewEye Gaze Behavior – Familiar vs. Unfamiliar
(Althoff & Cohen, 1999)
Familiar Faces Unfamiliar Faces
Eye Gaze Behavior as a Guilty Knowledge Test(Derrick, Moffit, & Nunamaker, 2010)
*This reaction can be attributed to Orienting Response Theory.
• Two Treatments: Innocent and Guilty• Guilty subjects assembled an improvised explosive device.• Both groups viewed a series of images while being monitored by an eye tracker.• One of the images was almost identical to the IED; however, a component was
missing.• Guilty subjects fixated on the missing component.
Familiarity Assessment Model
The Derrick et al. (2010) study evaluated eye gaze behavior (as a GKT) while subjects viewed images of objects.
RQ1: Can eye-tracking technology be used as a GKT to detect familiarity while subjects view images of faces?
