This gives insight into the cognitive processes underlying a wide variety of human behavior and can reveal things such as learning patters and social interaction methods.
Can eye tracking be improved? Eye tracking is following an object with your eyes without much head motion. It is important with any sport that involves a fast-moving ball. Good eye tracking will improve balance and reaction time. You can improve your eye tracking by watching the flight of a ball while keeping a book balanced on your head.
De plus, What is a Heterophoria?
Heterophoria or latent squint is defined as a condition in which eyes in the primary position or in their movement are maintained on the fixation point under stress only, with the aid of corrective fusion reflexes. When the influence of fusion is removed, the visual axis of one eye deviates.
What is it called when eyes jump during tracking?

Simple tricks include taping words to a spinning lazy Susan, a moving door, or a bouncing ball.

What do Saccades do?
A saccade is a rapid, conjugate, eye movement that shifts the center of gaze from one part of the visual field to another. Saccades are mainly used for orienting gaze towards an object of interest. Saccades may be horizontal, vertical, or oblique.

What is a manifest squint?
Manifest or latent: manifest squint is present when the eyes are open and being used; whereas in latent squint the eye turns only when it is covered or shut.
What causes Oscillopsia? What are the causes? Oscillopsia is caused by nervous system disorders that damage parts of the brain or inner ear that control eye movements and balance. One possible cause is the loss of your vestibulo-ocular reflex (VOR). This reflex makes your eyes move in coordination with the rotation of your head.

What does it mean when your eyes don’t track together?

Are humans blind 40 minutes a day?
Humans are blind for about 40 minutes per day because of Saccadic masking—the body’s way of reducing motion blur as objects and eyes move. 20/20 isn’t perfect vision, it’s actually normal vision—it means you can see what an average person sees from 20 feet.
What happens during a saccade? Saccades are rapid, ballistic movements of the eyes that abruptly change the point of fixation. They range in amplitude from the small movements made while reading, for example, to the much larger movements made while gazing around a room.
What causes a saccade?
The superior colliculus and frontal eye fields are thought to initiate saccades since activation of particular sites in these locations produces eye movements in a specified direction and distance that is independent of the initial position of the eyes in the orbit.
