Referring to fig. 1-3, an embodiment of the present invention provides a visual training method, which is trained by using a virtual reality display device and can provide lecture training for a person to be trained. The virtual reality display equipment is provided with a first display screen and a second display screen which are used for displaying contents to two eyes of a person to be trained respectively, a first training image is displayed on the first display screen, a second training image is displayed on the second display screen, background images are arranged in the first training image and the second training image, and lecture manuscript contents are also arranged in the first training image and/or the second training image. Virtual reality display device can be virtual reality wear-type display device, also is VR glasses, is called VR eye-shade, VR helmet etc. again, and the training image can be static image, also can be the dynamic video. The first training video and the second training video each have a background video, such as an image or a video related to speech content, or an image or a video of a perspective of a speaker, such as a speech hall or an auditorium, and the first training video and/or the second training video further have speech manuscript content for providing a speech prompt to the person to be trained. The speech manuscript content can be all speech lines or only speech synopsis or keywords. Show first training image and second training image through virtual reality display device, can make the speech training effect better.
In a preferred embodiment, the first training image and the second training image each have scene content of a perspective of a speaker, and the visual training method further includes a step of causing the scene content to make a change associated with a presentation performance of the person to be trained. The scene content is an embodiment of the background image. The scene content to be referred to makes a change related to the presentation performance of the trainee, which may be a color change, a motion change, etc. of a virtual property in the presentation field image (for example, a virtual indicator light is turned on), or a virtual firework added to be set off in the scene content, or a virtual audience makes a clapping motion or gives out booms and hists, etc. In some embodiments, when the person to be trained performs visual training and gives a speech, the assistant (e.g. a doctor or a friend) nearby may send a corresponding control instruction to the virtual reality display device according to the speech performance (e.g. speech accuracy, speech typhoon, etc.) of the person to be trained, and the virtual reality display device, after receiving the control instruction, makes the scene content make a change corresponding to the speech performance of the person to be trained. In other embodiments, the virtual reality display device may automatically detect and evaluate the performance of the speech of the person to be trained, and then control the scene content to make a change corresponding to the performance of the speech of the person to be trained. For example, a microphone and a voice recognition system may be disposed in the virtual reality display device, and perform voice recognition on the speech content of the person to be trained, compare the speech content with the speech manuscript content, and calculate the speech accuracy, or calculate the speech speed of the person to be trained, and accordingly evaluate the speech performance of the person to be trained, and output a corresponding control instruction for changing the scene content according to the evaluation result. Also can set up image device near first display screen and second display screen among the virtual reality display device, detect the eyeball position of being trained person, there is the condition of strabismus when detecting being trained person when the speech, then virtual spectator can send out hissing in the scene content, or does not have the condition of strabismus when detecting being trained person when the speech, then virtual spectator can carry out the clapping in the scene content.
In a further preferred embodiment, the scene content comprises a virtual audience, and the visual training method further comprises the step of making the virtual audience clap or make a sound in association with the performance of the speech of the person to be trained. The sound may be emitted through speakers provided on the virtual reality display device. Other specific implementation manners have been described in the above embodiments, and are not described herein again.
In a preferred embodiment, the first training image is a weakened image compared to the second training image. The method can be used to correct eye problems such as amblyopia and strabismus. Amblyopia refers to the condition of no obvious organic lesions in the eyeball, and amblyopia refers to the condition of the vision correction of one or both eyes still not reaching 0.8. The causes of amblyopia are mainly visual suppression and form deprivation. In the process of binocular vision, a competitive mechanism exists in visual centers, binocular visual input is unequal due to the form deprivation, the eyes with more visual information input compete with the eyes with less visual information input, the eyes with more visual information input become dominant eyes, and the eyes with less visual information input become inferior eyes and are inhibited, so that the visual development is retarded. Strabismus (squint) refers to the condition that two eyes cannot watch the target at the same time, and belongs to extraocular muscle diseases, and can be divided into two categories, namely common strabismus and paralytic strabismus. The common strabismus is characterized in that the eyeball does not have dyskinesia, and the strabismus of the first eye position and the second eye position are equal as the main clinical characteristics; paralytic strabismus has restricted eyeball movement, and diplopia can be congenital, traumatic or systemic disease. Amblyopia and strabismus can be corrected by visual training. When the prior art is used for vision training and correction, two eyes are trained mainly through a covering method, namely one eye is trained and the other eye is covered during training. Because only one eye can see the training image during training, and the condition that both eyes can see the outside is different from the condition that both eyes can see the outside during actual life, eye muscles can not form better conditioned reflex, so that the correction effect seems good during training, but the eye muscles can be easily restored to the state before correction when in actual life.
When the first training image is used for training the person to be trained with amblyopia or strabismus in a mode of weakening the image compared with the second training image, the effect of correction training can be effectively improved. Specifically, in use, the second training image displayed on the second display screen corresponding to one eye to be corrected (for example, the left eye) of the person to be trained is a normal corrected training image, and the first training image displayed on the first display screen corresponding to the other eye is a weakened image (compared to the second training image). Generally, the contents of the first training image and the second training image are substantially identical. The first training image is a weakened image compared with the second training image, and means that the degree of stimulation of the first training image to the eyes is weaker than the degree of stimulation of the second training image to the eyes. For example, the first training image is a blurred image compared with the second training image, or the first training image has a lower brightness or contrast than the second training image, or the second training image has more visual contents than the first training image, such as a lecture content or a moving image added to the second training image. During training, because the content seen by the trained eyes is a normal training image and the content seen by the other eye is a weakened image, the training of the trained eyes can be enhanced by the trained person, and a better correction effect is achieved. And because training image can be seen to both eyes during training, consequently can form the muscle memory of eyes with the scene that more is close to real life, when being met similar scene by the person of training in real life, its eye muscle can the conditioned reflex, and eyes demonstrate the state when correcting the training, consequently the correction effect can last for a long time, and the effect is better.
In other embodiments, the first training image and the second training image alternate as a weakened image. Since both eyes of some of the person to be trained need to be corrected, the first training image and the second training image can be alternately weakened to correct both eyes, that is, the first training image is a weakened image compared with the second training image in a period of time, and the second training image is a weakened image compared with the first training image in the next period of time. The virtual reality display device may be provided with a control button, and when the control button is pressed, the first training image and the second training image are alternately weakened and switched once, that is, if the first training image is a weakened image before the first training image, the second training image becomes a weakened image after switching. Or when the time length of the first training image or the second training image being the weakened image reaches a preset value, the first training image and the second training image are automatically switched in an alternating weakening manner, for example, when the time length of the first training image being the weakened image compared with the second training image reaches 30 minutes (which is equivalent to that one eye of the person to be trained corresponding to the second training image is strengthened and trained for 30 minutes), the control system automatically changes the second training image into the weakened image, and the first training image becomes the normal training image.
In a preferred embodiment, the first training image is a blurred image, the second training image is a clear image, and the second training image has lecture content. Referring to fig. 3, the training image of the left eye is a blurred image, the training image of the right eye is a clear image, and the training image of the right eye has lecture contents. In a preferred embodiment, the vision training method further comprises the step of adjusting the degree of blur of the first training image. In a preferred embodiment, the degree of blur of the blurred image is associated with the degree of vision of the eye of the person to be trained corresponding to the first training image. That is, the poorer the vision of the eye of the person to be trained corresponding to the first training image, the higher the blur degree of the blurred image. For example, if the vision of the person to be trained is only 0.5, the blur level of the blurred image may be 50%, and if the vision is 0.8, the blur level may be 20%, which is closer to what the person to be trained sees in normal vision and the training effect is better.
In a preferred embodiment, the vision training method further comprises the steps of:
receiving voice feedback of a person to be trained;
comparing the voice feedback of the person to be trained with the speech manuscript content to obtain the training accuracy of the person to be trained;
and if the training accuracy of the person to be trained does not meet the preset requirement, punishing the person to be trained or sending warning information to the person to be trained.
Specifically, the voice of the person to be trained can be received by the microphone, the voice is recognized, the recognized result is compared with the speech manuscript content, if the misreading rate (i.e. the ratio of the number of wrong words to the total number of words) of the speech manuscript content of the person to be trained exceeds a predetermined value or the number of wrong words exceeds a predetermined value, the training accuracy of the person to be trained is judged to be not meeting the preset requirement, at this time, a punishment of stopping training or a warning sound such as "please concentrate on training" can be given, and the person to be trained can train more intensively.
The vision training method may further include the steps of: and acquiring an image of a real environment, and combining the virtual image with the image of the real environment to obtain a first training image and a second training image. Specifically, the image of the real environment in front of the person to be trained can be acquired through the camera on the virtual Reality display device or the camera of the external device connected with the virtual Reality display device, and is combined with the virtual image to obtain the first training image and the second training image, so that the first training image and the second training image are Augmented Reality (AR) images, the content of the person to be trained seen in normal vision is closer, and the training effect is better. For example, a real image of the training environment in which the person to be trained is located can be obtained, and virtual audiences and lecture contents can be added to the image.
The vision training method may further include the steps of: and displaying the color blindness and/or color weakness correction image on the first display screen and/or the second display screen. By displaying the image for color blindness and/or color weakness correction, the patient with color blindness or color weakness can also be trained. Specifically, the color blindness (e.g., red-green-color blindness) or color weakness model may be simulated, the original image may be subjected to a step processing, a mapping table from a normal color space to a color blindness or color weakness color surface may be established, and the original image may be corrected according to the mapping table to obtain a color blindness or color weakness corrected image.
The vision training method may further include the steps of: an offset angle is applied to the second training image relative to the first training image. For a patient with strabismus, the images of both eyes are different from those of a normal person, and the images of the strabismus eyes are very different from those of the normal eyes, so that the brain selects a reasonable image generated by one normal eye and suppresses the image generated by the other strabismus eye. Therefore, when the person to be trained is a strabismus patient, the training image (i.e., the second training image) corresponding to the strabismus eye (the trained eye) can be applied with the same deviation angle as the strabismus direction, so that the difference between the image content fed back to the brain by the strabismus eye and the image content fed back to the brain by the other eye (the eye corresponding to the first training image) is smaller, and the strabismus eye is not inhibited. The deviation angle of the second training image may be smaller than the strabismus angle of the trained eye, thereby correcting the visual angle direction of the strabismus eye to the normal visual angle direction. The setting of the deviation angle may be determined based on the results of the examination of the eyes of the person to be trained by the doctor or optometrist.
In a further preferred embodiment, the vision training method further comprises the steps of: the angle of the offset angle is adjusted during the training process. Specifically, the angle of the deviation angle may be adjusted by an assistant for training, may be adjusted based on feedback (including voice feedback) of a person to be trained, or may be automatically adjusted, for example, by gradually decreasing the deviation angle, so as to gradually correct the viewing angle direction of the squint eyes toward the normal viewing angle direction.
The vision training method may further include the steps of:
displaying image contents with different virtual distances on the first display screen and/or the second display screen;
receiving the voice feedback of the trainee to the image content;
comparing the voice feedback of the person to be trained with the image content to obtain a test result;
and adjusting the image content according to the test result.
For patients with strabismus or amblyopia, the visual perception is very poor. Therefore, the first display screen and/or the second display screen display the image contents with different virtual distances (which can be different distances from front to back, or different distances from left to right), such as characters or figures, to train and test the person with strabismus or amblyopia, the image contents with different virtual distances can be simultaneously displayed in the same image frame, or sequentially displayed in different image frames, the person to be trained needs to read the characters or figures, then receives the voice of the person to be trained through the microphone, recognizes the voice, compares the recognized result with the image contents to judge whether the person to be trained answers the training questions correctly, if the answer is correct or the answer rate to a plurality of questions exceeds a predetermined value, can provide more difficult stereoscopic training, if incorrect or the answer rate to a plurality of questions is lower than a predetermined value, the difficulty rating of the training topic is left at the existing rating or is lowered by one rating. In other embodiments, if the answer is correct or the correct rate of answers to a plurality of continuous topics exceeds a predetermined value, images such as congratulations, cheers and the like may be displayed on the first display screen and/or the second display screen, or an option prompt indicating whether to enter a higher level may be displayed, if the answer is yes, the higher level may be entered, and correspondingly, if the answer is incorrect or the correct rate of answers to a plurality of continuous topics is lower than the predetermined value, images such as continuous refueling and the like may be displayed, and details thereof are not repeated herein.
