1. Familiarity Recognition in Automated Screening Environments: Utilizing Eye-Tracking Technology as an Intelligence Gathering Tool Jeffrey Gainer Proudfoot October 13, 2010 Readings in MIS

2. Background Information

3. Problem: Screening agents lack the ability, and technology, to identify persons with knowledge of, or familiarity with, wanted persons.

4. Eye-Tracking Technology

5. Literature Review Eye Gaze Behavior – Familiar vs. Unfamiliar (Althoff & Cohen, 1999) Familiar FacesUnfamiliar Faces

6. 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.

7. 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?

9. Expected Results Orienting Response – subjects will focus their eye gaze on the altered element of a familiar person’s face. Apprehension –subjects delivering the IED will demonstrate erratic eye gaze behavior during exposure to an image of the intended recipient.
