Vision testing and training system based on virtual reality

Abstract

The invention relates to a vision testing and training system based on virtual reality. The vision testing and training system comprises a head-wearing device, an image processing device in communication connection with the head-wearing device, an intelligent control device in communication connection with the head-wearing device and the image processing device, as well as a dizziness-preventing device and a remote terminal device which are in communication connection with the intelligent control device, wherein the head-wearing device comprises an image display device, an audio play device and a motion sensing device; the dizziness-preventing device is used for receiving the control of the intelligent control device so that the conversion angle of a vision testing image or a vision care image received by a user and the head position and angle shifting motion state of a user are synchronous, thus no dizzy feeling is generated during testing and health care, and therefore, the real sense of immediacy and sense of reality are achieved.

Description

technical field [0001] The invention belongs to the technical field of vision care, and in particular relates to a vision care system based on virtual reality. Background technique [0002] In recent years, the number of young people suffering from myopia has remained high, and has a tendency to increase year by year. This problem has seriously affected the healthy growth of young people, and has also attracted widespread attention from people from all walks of life. [0003] The current methods of visual acuity testing are mainly through eye chart identification or computer testing. Because of the high requirements on lighting and distance, the eye chart identification method is generally only suitable for professionals in hospitals, physical examination centers, and optician centers. It is not suitable for Check at home; the computer detection method is not suitable for family purchase because of expensive equipment. Since these two methods cannot provide people with a si...

Problems solved by technology

But this invention still has the following shortcoming or deficiency: (1), this invention can only carry out the training of correction and rehabilitation to myopia, and can not detect myopia; (3), the principle of the invention is to cooperate with the corresponding respiratory exercise when the eyes are doing extreme exercise, that is, from the beginning of muscle energy exercise, it is required to inhale until the breath is held, and when it returns to the normal position, it can be exhaled. The invention has relatively high requirements on people's coordination ability and physical fitness (especially lung capacity); (4), the distance between the video glasses display screen and the eyes is very short, which makes the eyes clearly see the "particles" on the screen, and the visual The experience is poor; (5), the device cannot adjust the image display according to the user's head movement, which may cause visual delay and cause various discomforts such as nausea and dizziness to the user

But this invention still has following shortcoming or deficiency: (1), this invention can only carry out the training of correction and rehabilitation to myopia, and can not detect myopia; The cost is high, which is not conducive to popularization to ordinary households; (3), users cannot freely use the health care instrument anytime and anywhere like portable devices, so it is not conducive to popularization to all myopia users
