In human vision, the useful field of view (or UFOV) is the visual area from which information can be extracted without eye or head movements.
[1][clarification needed] UFOV performance is correlated with important real-world issues, including risk of an automobile crash.
The first versions of the assessment and training programs were produced at Northwestern University by Robert Sekuler and Ball.
[9] Multiple studies have shown that improved UFOV performance generalizes to several real-world functions.
Perimetry tests check for the integrity of the visual system while UFOV tests the ability to pay attention to the information in the visual field particularly when under situations of increased demand for attention.
