Referring to fig. 1, the three-dimensional vision training system includes: a three-dimensional visual display device 100 and a motion device 200, wherein the three-dimensional visual display device 100 and the motion device 200 are communicatively connected via a network 300. The network 300 is used to provide a medium for a communication link between the three-dimensional visual display device 100 and the motion apparatus 200. Network 300 may include various connection types, such as wired communication links, wireless communication links, and so forth.

In an embodiment, the three-dimensional visual display device 100 comprises: the interactive display device comprises an interactive display unit 110, a processor 120 and a ranging unit 130, wherein the input end of the interactive display unit 110 is connected with the processor 120, and the output end of the ranging unit 130 is connected with the processor 120.

The interactive display unit 110 can display three-dimensional playing content, may be a special three-dimensional display screen, or may be a display screen with a three-dimensional conversion accessory, and can convert two-dimensional playing content into three-dimensional playing content. According to the naked eye 3D display technology, the three-dimensional conversion accessory may be a slit type liquid crystal grating device or a lenticular lens, or the like.

In an embodiment, the three-dimensional conversion accessory is a slit type liquid crystal grating device, and the technical principle is that a slit type grating is added in front of a display screen of the interactive display unit 110, and when an image which should be seen by a left eye is displayed on the liquid crystal screen, an opaque stripe can block a right eye; similarly, when the image which should be seen by the right eye is displayed on the liquid crystal screen, the opaque stripes can shield the left eye, and the user can see the 3D image by separating the visual pictures of the left eye and the right eye, so that the two-dimensional playing content displayed on the display screen is converted into the three-dimensional playing content.

In an embodiment, the three-dimensional conversion accessory is a cylindrical lens, and the technical principle of the three-dimensional conversion accessory is that pixel points corresponding to left and right eyes are projected in the left and right eyes respectively through the refraction principle of the lens to realize image separation, so that a user can see a 3D image and convert two-dimensional playing contents displayed on the interactive display unit 110 into three-dimensional playing contents.

In an embodiment, the three-dimensional conversion accessory is a slit-type liquid crystal grating-type film or a lenticular-type film, that is, the slit-type liquid crystal grating or the lenticular lens is made into a three-dimensional display conversion film with a special structure, which may be in the form of a mobile phone film, and can be set to have different sizes and specifications according to different sizes of the interactive display unit 110.

In an embodiment, the distance measuring unit 130 may implement distance detection by using infrared detection or pupil detection.

Based on the three-dimensional visual training system architecture, various embodiments of the three-dimensional visual training method of the embodiment of the application are provided.

As shown in fig. 2, fig. 2 is a flowchart of a three-dimensional visual training method provided in an embodiment of the present application, including but not limited to step S110 and step S140.

The user visual training information includes: the user account name and/or the user's eyesight information and/or the user's visual training progress and/or the user's training session record and/or the user's training mode.

In one embodiment, the user account name may include a user account and a corresponding user password, and the processor stores the corresponding user account and the visual training data of the user, and generates a user vision health profile for the user, so as to monitor the visual training result. If the user is a new user, a user account name is established for the new user.

In one embodiment, the vision information of the user is the eye degree of the user and the corresponding time for measuring the vision, so that the change trend of the eye degree of the user can be counted conveniently, and a further vision training scheme or a correction suggestion can be provided for the user.

The guiding instruction can guide the user in the form of words or voice on the interactive display unit.

In one embodiment, referring to fig. 3, step S120 may include, but is not limited to, the following steps:

and step S121, generating a three-dimensional visual training marker.

In one embodiment, the three-dimensional visual training marker may be a three-dimensional sphere or a three-dimensional ribbon.

And S123, generating three-dimensional visual training contents corresponding to the three-dimensional visual training markers according to the rhythm motion mode.

In one embodiment, the three-dimensional visual training marker is in a motion state corresponding to different rhythmic motion modes to form three-dimensional visual training content, and the problem of plane fixation which cannot be solved by plane training can be avoided through three-dimensional visual training. In addition, since the plane training can only move to the oblique and the rectus muscles of the eye, it is difficult to exercise the ciliary muscles and the crystalline lens. Thus, the present embodiment utilizes three-dimensional vision training in conjunction with ciliary muscle and lens movement to improve the accommodative power of the eye.

Research on the incidence and the adjustment of the myopic eye shows that the myopic eye has reduced flexibility in remote adjustment and obviously slows down the reaction to positive and negative defocus, so that certain relation exists between eye adjustment parameters and the myopic eye. The myopia is prone to asthenopia due to convergence and abnormal accommodation. Therefore, the present embodiment utilizes three-dimensional vision training in conjunction with ciliary muscle and lens movement to improve the eye's vision accommodation in accordance with the accommodation principles of myopic eyes described above. The three-dimensional visual training can simulate real and natural environmental states, the eyes of a user can independently perform three-dimensional dynamic visual training by watching the three-dimensional visual training marker, the fusion function of the eyes is gradually established through the stimulation effect of the visual environment, the stereoscopic vision is improved, good stereoscopic vision is established in the key period of visual development or the vision correction period, and the vision is effectively improved.

For example, according to the corresponding rhythm movement mode, the three-dimensional vision training marker is in the corresponding movement state, the eyes of the user move according to the movement state along with the change of the three-dimensional vision marker, the training operations of looking far and looking near, eyeball movement, eyeball muscle movement along with the movement, eyeball pursuit following and the like are trained, the eyes of the user carry out all-around movement, meanwhile, crystalline lens, ciliary muscle and extraocular muscle are trained, the asthenopia is obviously relieved, and the myopia can be prevented or the vision problem can be improved through long-term three-dimensional vision training.

Fig. 4 shows a trace diagram of wave displacement of the three-dimensional sphere for up displacement, down displacement, left displacement and right displacement. The three-dimensional sphere may perform two or more displacement types at the same time, for example, perform left displacement and up displacement at the same time, so as to implement left-up displacement, which is not limited herein.

In an embodiment, the first law may be a time and speed law, for example, the three-dimensional sphere moves upward at a constant speed at a first speed, reaches a first position after the first time, then moves downward and leftward at a second acceleration after the first position stays for a second time, and then reaches a second position after the third time, and different moving speeds, moving accelerations, or moving times may be set in combination with displacement types to generate a continuous motion trajectory of the three-dimensional sphere, so as to form a stereoscopic motion picture in a rhythm motion mode, so that the eyes of a user move along the continuous motion trajectory of the three-dimensional sphere, and achieve the purpose of three-dimensional visual training.

It can be understood that the interactive display unit of the three-dimensional visual display device has a certain boundary, the shape of the interactive display unit is not limited, and a rectangle is illustrated in fig. 4 as an example. In one embodiment, the displacement range of the three-dimensional sphere does not exceed the boundary of the interactive display unit (refer to the boundary of the interactive display unit in fig. 4). Furthermore, a buffer area (refer to a dotted line range in fig. 4) is set according to a boundary of the interactive display unit, and a displacement range of the three-dimensional sphere does not exceed the buffer area of the interactive display unit, so that the three-dimensional sphere is always a complete sphere presented to a user, and the three-dimensional sphere is not displayed completely after moving to the boundary, and is cut as usual, thereby affecting the visual training experience of the user.

2) Zoom mode

When the zoom mode is selected, the three-dimensional visual training content includes:

acquiring a second rule;

and controlling the three-dimensional visual training marker to be amplified or reduced according to a second rule, and forming continuous three-dimensional visual training content.

Fig. 5 shows a schematic diagram of a three-dimensional sphere being enlarged or reduced, and in combination with the above displacement modes, for example, the three-dimensional sphere can be displaced and zoomed at the same time, for example, being enlarged at the same time as being displaced to the left.

In an embodiment, the second law may be a time and speed law, for example, the three-dimensional sphere gradually enlarges while moving upward at a third speed, reaches a third position after a fourth time, gradually reduces while moving rightward and downward at a third acceleration after staying at the third position for a fifth time, reaches a fourth position after a sixth time, and the like, the zoom mode may be set in combination with the displacement type to generate a continuous motion trajectory of the three-dimensional sphere to form a stereoscopic motion picture in a rhythm motion mode, so that the eyes of the user move along the continuous motion trajectory of the three-dimensional sphere, and simultaneously, since the three-dimensional sphere is enlarged or reduced during the motion process, the eyes can be trained to see far and near, move with the eyeball muscle, follow the eyeball to follow the eyeball, and perform the like, so that the eyes of the user perform omnidirectional motion, meanwhile, the lens, ciliary muscles and extraocular muscles are trained, pseudomyopia is corrected, true myopia is prevented, myopia deepening is controlled, visual fatigue is effectively relieved, visual functions are improved, visual fatigue is obviously relieved, and the purpose of three-dimensional visual training is achieved.

According to the naked eye 3D display technology, the three-dimensional conversion accessory may be a slit type liquid crystal grating device or a lenticular lens. Referring to fig. 7, a lenticular lens is taken as an example to illustrate a technical principle of naked eye 3D, and two images (a left image and a right image) with parallax on a lenticular lens screen (a screen with a certain thickness and composed of cylindrical prisms with a certain distance) are respectively projected into corresponding eyes, so that the left eye and the right eye are shielded by opaque stripes due to the slight parallax generated by the distance between the two eyes, and pixels seen by the left eye and the right eye are not the same, thereby forming a left eye image and a right eye image, and simulating a principle of parallax imaging of human eyes, thereby forming a three-dimensional picture in the brain of a user.

Referring to fig. 6a, due to the parallax (due to the existence of the interpupillary distance) between the left eye and the right eye, there is a first distance between the left eye image and the right eye image on the screen, and the distance between the left eye image and the right eye image corresponding to the three-dimensional visual training marker is gradually adjusted to meet a first preset distance range, that is, the first distance is within the first preset distance range, so that the imaging positions of both eyes (the virtual image a' of the object a in the figure) are located in the screen, which is called as on-screen display.

Referring to fig. 6b, due to the parallax (due to the pupil distance) between the left eye and the right eye, the left eye image and the right eye image corresponding to the three-dimensional visual training marker are gradually adjusted to coincide, so that the imaging positions of the two eyes (the virtual image a' of the object a in the figure) are located on the screen, which is called screen point display.

Referring to fig. 6c, because there is a parallax between the left eye and the right eye (because of the existence of the interpupillary distance), there is a second distance between the left eye image and the right eye image on the screen, and the distance between the left eye image and the right eye image corresponding to the three-dimensional visual training marker is adjusted in a gradual manner to satisfy a second preset distance range, that is, the second distance is within the second preset distance range, so that the imaging positions of both eyes (the virtual image a' of the object a in the figure) are located outside the screen, which is called as an off-screen display.

In an embodiment, the first preset distance range and the second preset distance range may be set according to an empirical value.

In one embodiment, the third law may be a time-speed and distance law, such as a three-dimensional sphere changing the first distance at a constant speed at a fourth speed, and the first distance is within a first preset distance range, so that the three-dimensional sphere is displayed inside the screen at a seventh time (the user looks as the three-dimensional sphere is farther and farther), then after stopping for the eighth time, the second distance is changed at the fifth speed in an accelerating way, and the second distance is gradually positioned in the second preset distance range, so that the three-dimensional sphere is displayed outside the screen in the eighth time (the user looks like that the three-dimensional sphere is closer and closer), the displacement type and the zooming mode can be combined at the same time to generate a continuous motion track of the three-dimensional sphere and form a stereoscopic motion picture in a rhythm motion mode, so that the eyes of the user move along the continuous motion track of the three-dimensional sphere.

Because the three-dimensional sphere can be enlarged or reduced in the movement process, the training operations such as far and near vision of eyes, eyeball movement, eyeball muscle movement and eyeball pursuit following can be trained, and during training, a user can watch the three-dimensional vision training marker to enable the sight lines of two eyes to form intersection points at the front point and the back point of eyes and continuously circulate (namely, the three-dimensional vision training marker is displayed on a screen or displayed on the screen according to a third rule) so that the sight line range of the user can be increased and dispersed to the maximum extent, the crystalline lens of the eyes of the user is driven to move greatly, ciliary muscles of the user are relaxed, the tension caused by long-term eye use is relieved, the eyes have enough flexibility and storage capacity, the asthenopia is obviously relieved, and the purpose of three-dimensional vision training is achieved.

It can be understood that the three rhythm motion modes can be combined according to the requirements corresponding to the user visual training information to generate different three-dimensional visual training contents and generate personalized training contents for the user. Furthermore, different training courses can be set according to different three-dimensional visual training contents, so that a user can quickly select a proper training course according to training requirements.

Step S130, when the training phase is the visual training phase, performing a first operation, referring to fig. 8, the first operation includes, but is not limited to, the steps of:

in step S131, the ranging unit acquires user distance information and transmits the user distance information to the processor.

In an embodiment, the distance measuring unit may implement distance detection by using infrared detection or pupil detection.

The technical principle of infrared detection is as follows: the distance measurement is carried out by utilizing the non-diffusion principle during the transmission of infrared rays, because the refractive index of the infrared rays is very small when the infrared rays pass through other substances, when the infrared rays are sent out from the distance measurement unit and touch a reflector, the infrared rays are reflected back to be received by the distance measurement unit, and then the distance can be calculated according to the time from the sending to the receiving of the infrared rays and the transmission speed of the infrared rays.

The technical principle of pupil detection is as follows: the distance measurement unit collects a face image by using the camera, processes the face image, performs face detection and eye positioning on the processed face image to obtain two pupil coordinates, calculates the interpupillary distance in the face image according to the pupil coordinates, and calculates the distance from the eyes (namely, users) to the three-dimensional visual display equipment according to the triangular similarity principle by combining the actual interpupillary distance and the camera focal length.

For example, the distance measuring unit obtains the pupil distance information of the user by using a pupil detection method, obtains the user distance information according to the pupil distance information, and sends the user distance information to the processor for the next determination.

Step S132, the processor sends the three-dimensional visual training content and the visual training guiding instruction to the interactive display unit so as to guide the user to perform visual training according to the three-dimensional visual training content within a preset distance.

In an embodiment, after obtaining the user distance information, the processor determines whether the user can currently perform three-dimensional visual training according to the distance:

1) when the user distance information is within the first preset threshold range, the processor outputs three-dimensional visual training content and a visual training guide instruction to the interactive display unit so as to guide the user to perform visual training according to the visual training guide instruction.

In this embodiment, if the processor determines that the user is within the first preset threshold range, it is determined that the user can currently perform three-dimensional visual training, and outputs three-dimensional visual training content and a visual training guidance instruction to the interactive display unit, and the user performs visual training according to the corresponding visual training guidance instruction by viewing the three-dimensional visual training content displayed by the interactive display unit. For example, the visual training guidance instructions include: the visual training guidance instruction can be a voice reminding instruction, and the like, wherein the visual training guidance instruction includes that the eyeballs are required to follow the three-dimensional ball in the screen, the timer is required to be used for resting for 30 seconds in a closed eye mode, the timer is required to be used for opening the eyes and rotating the eyeballs in a wave shape along with the three-dimensional belt-shaped object in the screen.

In one embodiment, the vision training guidance instruction is used for guiding the user to perform overlook exercise in the three-dimensional vision training process, for example, looking up at a place 5 meters ahead and left, and overlook the distant place, so that the visual fatigue can be relieved to a certain extent, the overlook exercise in a reciprocating cycle is added in the three-dimensional vision training process for super-strong training, and the visual field and depth range are expanded by combining a near virtual 3D environment with a far real environment, so that the vision training effect is further improved.

2) When the user distance information is out of the first preset threshold range, the processor outputs a distance state abnormal indication to the interactive display unit to guide the user to adjust the distance so as to enter the first preset threshold range for visual training.

In this embodiment, if the processor determines that the user is outside the first preset threshold range, it is determined that the user is too far away from the three-dimensional visual display device to perform effective three-dimensional visual training, and then outputs a distance status abnormal indication to the interactive display unit, where the distance status abnormal indication may be in a voice or text form to remind the user, for example, "please move forward too far away from the current distance", so as to avoid the effect of visual training from being affected by too far distance.

Step S140, when the training phase is the motion adjustment phase, performing a second operation, wherein the second operation specifically is:

the processor acquires the motion state information sent by the motion device and switches the training stage guide instruction according to the motion state information so as to guide the user to switch different training stages.

In one embodiment, the exercise device includes a motion sensor, the processor obtains exercise state information sent by the exercise device, and when the training phase guide instruction is the exercise adjustment phase: the motion sensor sends the motion parameters to the processor, and the processor judges whether the visual training stage needs to be switched back or not according to the motion parameters.

In the embodiment, three-dimensional visual training and movement are combined, so that the visual training stage is switched to the movement adjusting stage at intervals in order to avoid overlong eye use time, and the visual training stage is switched back again after the rest is finished, so that the current training plan is completed. For example, after 10-20 minutes of visual training, the user is switched to a movement adjustment stage to slightly rest for 3-5 minutes, and meanwhile, when the user moves on the movement device, more brain excitement can be obtained, visual balance can be obtained during movement, the visual training effect is increased, and the three-dimensional visual training content is combined with the movement device, so that the user can train the eye adjusting function in the movement process, the visual training compliance of the user is improved, and the visual training effect is further improved.

It is understood that the sequence and times between the vision training phase and the exercise adjusting phase are not limited, and can be set according to the training requirements of the user.

In addition, in an embodiment, after the visual training of the preset time period, the training effect evaluation is performed on the user to obtain the visual information of the user, for example, the visual detection is performed on the user, and then the visual training information of the user is updated according to the visual information of the user, or a glasses fitting guidance suggestion is sent according to the visual information of the user.

In this embodiment, after a certain period of three-dimensional visual training, the myopia of the user may be alleviated, and therefore, it is necessary to determine whether to update the visual training scheme of the user or provide a prescription guidance suggestion for the user according to the current visual detection information of the user, so as to avoid further deterioration of the vision of the user due to an inappropriate glasses degree.

In an embodiment, the vision information of the user is the eye power of the user, so the vision training information of the user is updated according to the currently measured vision information of the user, and then the vision training scheme is adjusted by a preset power difference value to perform glasses-wearing vision training with stepwise power decreasing, wherein the preset power difference value may be set according to specific needs, for example, may be 25 degrees or 50 degrees. In one embodiment, for example, after a certain period of time of glasses-wearing three-dimensional vision training, the myopia degree of the user is reduced from 600 degrees to 550 degrees, and the preset degree difference is 50 degrees, the current degree of the user is obtained through optometry, the vision training scheme is adjusted according to the current 550-degree myopia condition, for example, the training time is reduced, the training intensity is reduced, the training content is changed, and then glasses fitting guidance suggestions are provided for the user; after the glasses-wearing three-dimensional visual training for a certain time, the glasses degree and the visual training scheme are further adjusted according to the preset degree difference value, and the like, the glasses-wearing visual training with the gradually decreased degrees is realized, and the further deterioration of the vision of the user is avoided.

In an embodiment, the user may also obtain the user's myopia number, and then perform the stepwise number adjustment to perform the glasses-wearing visual training, for example, if the user himself is deemed to be 300 degrees, the user is advised to wear 250-degree glasses to perform the three-dimensional visual training, after the glasses-wearing three-dimensional visual training for a certain period of time, the user's myopia number decreases from 300 degrees to 250 degrees, and then wears 200-degree glasses to perform the three-dimensional visual training, and so on, and perform the stepwise number adjustment to perform the glasses-wearing visual training.

Compared with the related technology, the three-dimensional visual training method applied to the three-dimensional visual training system comprises the steps of obtaining user visual training information and generating three-dimensional visual training content and a guiding instruction, obtaining user distance information and sending the user distance information to a processor when a training stage is a visual training stage, and sending the three-dimensional visual training content and the visual training guiding instruction to an interactive display unit by the processor so as to guide a user to perform visual training according to the three-dimensional visual training content within a preset distance; when the training stage is a motion adjusting stage, the processor acquires motion state information sent by the motion device and switches a training stage guide instruction according to the motion state information so as to guide a user to switch different training stages. Utilize three-dimensional visual training content to carry out visual training, avoid the inherent long-time drawback of closely using the eye of plane visual training, can carry out eye movement, eyeball muscle walks about, the eye ball is tracked and is followed etc. comprehensive training, it is more nimble to make user's eye movement, improve comfort level and definition that the user looked the thing, effectively alleviate visual fatigue, and three-dimensional visual training content combines telecontrol equipment, let the regulatory function of training the eye among the user's motion process, correct pseudomyopia, prevent true myopia, control myopia deepens, effectively alleviate visual fatigue, improve visual function, improve user visual training compliance, further improve visual training effect.
