Abstract: A field of vision assessment is performed by reported positional feedback of visual markers at an outer circumference of a subject's field of vision. An array of visual markers arranged in a grid is rendered near a peripheral vision limit of the subject. The visual markers are disposed at known locations relative to an origin of the field of vision of the subject. Based on reported visual markers, a mapping of the visual markers to the location denotes a point on a periphery of limit of the visual field. The mapped points define vertices of a polyhedron having edges denoted by the vertices and the origin. The volume of the resulting polyhedron correlates to the field of vision of the subject, since as the periphery of the field of vision increases, the computed volume also increases.
