A Novel Virtual Reality Design of Portable Automatic Perimetry

Due to delayed diagnosis and treatment, millions of people, especially senior citizens, suffer from visual field loss even long-term blindness. However, many blindness could be prevented by popularizing the routine inspection of visual field. In this paper, we propose a novel virtual reality design of portable automatic perimetry. The virtual reality (VR) device provides a non-light and full-field environment. Combined with its portability, it makes external light shielded, and full-field examination feasible in normal clinic ward or outpatient department as a kind of regular physical examination. To make it easier to use, we also offered several automatic human-VR interaction modes, including using straightforward eye tracking to replace traditional mouse click or button press. Owing to more friendly interaction and better portability, the novel virtual reality design of portable automatic perimetry facilitates both the subjects and clinicians to improve the efficiency of routine inspection.
