Classical image of the shape and size of the visual field [28]. The outer boundaries of peripheral vision correspond to the boundaries of the visual field as a whole. For a single eye, the extent of the visual field can be (roughly) defined in terms of four angles, each measured from the fixation point, i.e., the point at which one's gaze is directed.
A peripheral head-mounted display (PHMD) is avisual display (monocular or binocular) mounted to the user's head that is in the peripheral of the user's field of view (FOV) / peripheral vision. Whereby the actual position of the mounting (as the display technology) is considered to be irrelevant as long as it does not cover the entire FOV. While ...

Processing speed also affects peripheral vision. The faster your brain, the larger the visual field you can take in with every glance — giving you enough time to see a hazard coming at you from ...
An examiner presents a test light of variable size and intensity. The light may move towards the center from the perimeter (kinetic perimetry), or it may remain in one location (static perimetry). The Goldmann method is able to test the entire range of peripheral vision and has been used for years to follow vision changes in glaucoma patients. [3]
The researchers also found the smile — or frown — appears to change depending on where it is in a viewer's peripheral vision. They simulated this effect on test subjects using blur.
