Yarbus eye tracker from the 1960s. In the 1800s, studies of eye movement were made using direct observations. For example, Louis Émile Javal observed in 1879 that reading does not involve a smooth sweeping of the eyes along the text, as previously assumed, but a series of short stops (called fixations) and quick saccades.

An example of eye movement over a photograph over the span of just two seconds. Eye movement includes the voluntary or involuntary movement of the eyes. Eye movements are used by a number of organisms (e.g. primates, rodents, flies, birds, fish, cats, crabs, octopus) to fixate, inspect and track visual objects of interests.
Saccadic movements is the type of eye movement that makes jumps from one position to another position and is used to rapidly scan a particular scene/image. Lastly, pursuit movement is smooth eye movement and is used to follow objects in motion.
Spatial intelligence is an area in the theory of multiple intelligences that deals with spatial judgment and the ability to visualize with the mind's eye. It is defined by Howard Gardner as a human computational capacity that provides the ability or mental skill to solve spatial problems of navigation, visualization of objects from different angles and space, faces or scenes recognition, or to ...
The laboratory study of change blindness began in the 1970s within the context of eye movement research. George McConkie conducted the first studies on change blindness involving changes in words and texts; in these studies, the changes were introduced while the observer performed a saccadic eye movement. Observers often failed to notice these ...
The transient system is responsible for controlling eye movements, and processing the larger visual environment around us. When these two processes do not work in synchronization this can cause reading disabilities. This has been tested by having children with and without reading disabilities perform on tasks related to the transient systems ...
Eye movement behaviour in scene viewing differs between different levels of cognitive development. Fixation durations shorten and saccade amplitudes lengthen with the increase in age. In children, the development of saccades to the amplitude normally found in adults have occur earlier (4–6 years old) than the development of fixation durations ...
Brainspotting is a psychotherapy technique that attempts to help people process psychological trauma or other problems via eye movements. [1] [2] Practitioners of this technique use a pointer to direct a client’s eye gaze in order to send signals to the brain to resolve psychological or physical concerns. [2]
