This document discusses the potential for developing a "visual fingerprint machine" (VFM) that could identify individuals based on their unique eye movement patterns during voluntary eye pursuits (VEP). It notes that 70% of US police departments currently use license plate scanners and suggests VEP could enable similar identification of individuals. It reviews the components of VEP, including smooth pursuit movements and saccades, and how they differ between horizontal and vertical axes. The goal is to classify individuals' unique "visual fingerprints" based on their VEP components and store them, then use VF testing to identify individuals later.
