Eye tracking and biometrics LinkedIn Learning, formerly Lyndacom
Ocular biometry refers to the measurement of anatomical dimensions of the eye, which include corneal curvature (keratometry), axial length, and anterior chamber depth. These measurements are primarily used to calculate the appropriate power of the intraocular lens (IOL) to be implanted during cataract surgery..
How does biometric eye tracking work?
Biometric iris recognition scanners work by illuminating the iris with invisible infrared light to pick up unique patterns that are not visible to the naked eye. Iris scanners detect and exclude eyelashes, eyelids, and specular reflections that typically block parts of the iris..

Is eye movement biometric data?
Eye movements are a relatively novel data source for biometric identification..
Is eye-tracking biometric data?
Eye-tracking is a technique that measures where users look, how long they look, and how they move their eyes across a screen or a physical environment. Biometric data is a type of physiological data that measures users' bodily responses, such as heart rate, skin conductance, facial expressions, and brain activity..
What is the biometry of the eye?
Ocular biometry refers to the measurement of anatomical dimensions of the eye, which include corneal curvature (keratometry), axial length, and anterior chamber depth. These measurements are primarily used to calculate the appropriate power of the intraocular lens (IOL) to be implanted during cataract surgery..
What is the purpose of biometry?
Biometrics is best described as a personal identity verification system, meaning that your personal identity is verified by using individual and unique physical characteristics such as your fingerprints, hand geometry, speech, eyes, handwriting, or facial recognition..
Conclusion. The features that could be extracted from eye-tracking data included pupil size, saccade, fixations, velocity, blink, pupil position, electrooculogram (EOG), and gaze point. Fixation was the most commonly used feature among the studies found.

Abstract. Purpose: To develop models for assessing the differential growth of the fetal face along its horizontal and vertical axes, as well as of the orbit and
Just like your fingerprints, using the iris of the eye for identification is unique to each individual person, making it just as useful for several forms of security.
OLCR is a non-contact, noninvasive biometric method providing extensive biometric status by simultaneous measurement of central corneal thickness (CCT), ACD, corneal curvature radius (K1 and K2 keratometry), PD, astigmatism (AST), white-to-white corneal diameter (WTW), axial length of the eye (AL), LT and retinal
Using this method, the system measures human's eyes reaction for visual stimulation. The eyes of the person who is being identified follow the point on the computer screen and eye movement tracking system is used to collect information about eye movements during the experiment.
Are ocular parameters measured by SS-OCT-based biometric devices used for pre-cataract surgery?
The purpose of this study was therefore to compare the ocular parameters measured by these two recent biometers to those measured by the IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany), the first SS-OCT-based biometric device and one of the most commonly used devices for pre-cataract surgery measurements 14.
Can video cameras be used for eye movement biometrics?
Epub 2016 Apr 7. Eye movements are a relatively novel data source for biometric identification. When video cameras applied to eye tracking become smaller and more efficient, this data source could offer interesting opportunities for the development of eye movement biometrics.
What is ocular biometry?
Ocular biometry involves anatomical measurements of the eye, including:
the axial length (AL)
keratometry and anterior chamber depth (ACD) and includes
anterior segment biometry
for which only the front third of the eye is measured.
