Eye tracking device is a tool created to help measure eye and head movements. The first devices for tracking eye movement took two main forms: those that relied on a mechanical connection between participant and recording instrument, and those in which light or some other form of electromagnetic energy was directed at the participant's eyes and its reflection measured and recorded.
Eye movement in music reading is an extremely complex phenomenon that involves a number of unresolved issues in psychology, and which requires intricate experimental conditions to produce meaningful data. Despite some 30 studies in this area over the past 70 years, little is known about the underlying patterns of eye movement in music reading.
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.

There are particular factors which affect where eye movements fixate upon, these include bottom-up factors inherent to the stimulus, and top-down factors inherent to the viewer. Even an initial glimpse of a scene has been found to generate an abstract representation of the image that can be stored in memory for use in subsequent eye movements ...
The study of eye movements in reading allowed researchers to map out the perceptual span (moving window paradigm [23] [24]), the nature of the extrafoveal information extracted during a fixation, for instance orthographic and phonological information (boundary paradigm) [25] [26] [27] or the relative influence of attention versus visual acuity ...
Changes in the eye can help predict other health concerns in the body, such as diabetes and high blood pressure. A new study has identified a set of 29 vascular health indicators on the retina ...

Oculesics is one form of nonverbal communication, which is the transmission and reception of meaning between communicators without the use of words.Nonverbal communication can include the environment around the communicators, the physical attributes or characteristics of the communicators, and the communicators' behavior of the communicators.
