Abstract Oculomotor Plant Mathematical Model (OPMM) Experimental Methodology
Apparatus: The experiments were conducted with a Tobii x120 eye tracker.This study presents a new biometric approach that involves an estimation of the
unique oculomotor plant (OP) or eye globe muscle parameters from an eye
Eye Movement Invocation Task: The stimulus was presented as a `jumping point'
with vertical coordinate fixed to the middle of the screen.
movement trace. It includes both behavioral and physiological human attributes, is
difficult to counterfeit, non-intrusive, and could easily be incorporated into existing
biometric systems to provide an extra layer of security
Participants: The test data consisted of 68 student volunteers ages 18-25 with an
average age of 21.2 and standard deviation of 3.2, 24 males and 44 females, with
biometric systems to provide an extra layer of security.
Biometrics: Refers to methods for uniquely recognizing humans based upon one or
more intrinsic physical or behavioral traits There are two major categories of
normal or corrected-to-normal vision. Only 41 subject records passed the selection
criteria, resulting in mean accuracy of 1.25º (SD=0.77) and a mean invalid data
