Abstract

The invention discloses a multifunctional visual function detection device based on a VR technology and eye movement tracking. The device comprises virtual-reality head-mounted equipment, a displayer,a processor, an eye movement tracking sensor and a control terminal, wherein the displayer is arranged in the virtual-reality head-mounted equipment, the processor is in signal connection with the displayer, the control terminal is in signal connection with the processor and the eye movement tracking sensor, and the processor is used for sending an instruction to the displayer to enable the displayer to present corresponding detection content. The eye movement tracking sensor is used for acquiring response data of the eyeballs of a subject under the action of a visual stimulus on the displayer. The invention also provides a detection method. The detection method comprises one or more of non-social object exploration, a reading test, facial identification and re-identification and sortingof motion tracking reference points and color chess pieces. Through the scheme, the problems of monotonous functions, poor accuracy and the like of existing visual function detection devices are solved.

Description

technical field [0001] The present invention relates to medical equipment and related technical fields, in particular to a multifunctional visual function detection device and method based on VR and eye tracking. Background technique [0002] A comprehensive and adequate visual examination and assessment of ophthalmic patients is the key to the diagnosis and treatment of ophthalmic diseases. In addition to routine optometry examinations such as visual acuity, visual field, color vision, and contrast sensitivity, ophthalmic examinations currently used in clinical practice also include visual functions such as eye movement, accommodation and vergence, sensory fusion, stereopsis, and motor vision. examine. However, most of the current visual function inspection equipment is single-function, bulky, expensive, and requires high professional ability of inspectors, so it is difficult to widely develop and popularize. In addition, the inspection results of these devices are often ...
