Eyeand

Eyeand is a term used in cognitive science and human-computer interaction to describe an integrated approach to study how eye function and cognitive processing converge to guide perception and action. While not a formal discipline, Eyeand serves as a conceptual framework for examining how visual input from the eye and higher-level processes such as attention, memory, and decision making interact in real time.

Origins of the term are diffuse, but it is commonly employed to emphasize cross-disciplinary analysis that treats ocular data as informative about mental states. The scope of Eyeand includes anatomy and physiology of the eye, eye movements (such as saccades and fixations), pupillary responses, and the perception of visual scenes, together with how these elements influence, and are influenced by, attention, learning, and task goals.

In research, Eyeand is used alongside methods like eye-tracking, gaze-path analysis, and pupillometry to infer cognitive mechanisms from where and how a person looks. In design and applied contexts, Eyeand guidelines aim to align interface layouts with natural eye behavior, minimize cognitive load, and improve accessibility, especially for users with visual or attentional differences.

Applications span experimental psychology, usability testing, education, clinical assessment, and augmented or virtual reality, where predicting gaze patterns can improve content presentation and interaction flow. Critics note that Eyeand is a broad, descriptive label rather than a single theory, and its usefulness depends on careful operationalization of measurements and models.
