Description

Technical Field

[0001] The present invention relates to the field of anti-squint control methods, and in particular to an anti-squint control method and system for a mixed reality head display. Background Art

[0002] Nowadays, living space is small, which leads to people spending most of their time indoors. They often use their eyes at close range, and the human eye is highly adaptable and will adjust itself to close distances. At the same time, the popularity of electronic products has greatly increased the chances of playing with electronic products indoors. In addition, the distance and posture issues are not taken seriously, which can easily lead to excessive eye fatigue, resulting in eye diseases becoming more common, and the age group is getting younger and younger. This undoubtedly poses a potential threat to the health of adolescents who are in the developmental period. Especially for children, if eye diseases are not discovered and controlled early, they are likely to cause children to suffer from amblyopia and strabismus. These eye diseases can cause lifelong damage to children's visual function and even affect brain development.

[0003] Intermittent exotropia is a common eye disease in children. It is a type of strabismus between common exotropia and exophoria, which refers to the state of separation of the visual axis. It often occurs when looking far away in the early stage of the disease and progresses with the progression of the disease. The most prominent feature of intermittent strabismus is that the angle of strabismus changes greatly, but there is still partial ability to control the eye position. If the disease continues to develop, it may become constant exotropia and completely lose binocular vision function. At present, there are many methods to prevent strabismus on the market, mainly to improve the glasses worn by children, so as to intervene by improving the structure of the glasses. However, this solution does not take into account the eye position problems of myopic and strabismus children and the balance of eye adjustment and convergence when the human eye looks at close range, so it cannot achieve the effect of prevention and treatment or the effect is not obvious, and this solution requires children to wear the glasses all the time, which is obviously a burden for people who do not like to wear eye tools for a long time.

[0004] Therefore, it is necessary to propose a control scheme for preventing the eyes from squinting to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide an anti-strabismus control method and system for a mixed reality head display, so as to solve the problem in the prior art that the effect of preventing and treating eye strabismus cannot be achieved or the effect is not obvious by wearing glasses for a long time.

[0006] To achieve the above objectives, in a first aspect, the present invention provides an anti-squint control method for a mixed reality head display, the method comprising:

[0007] In response to the target input, two training lines are formed that intersect at the vertex, each training line having three-color fixation balls arranged equidistantly in the order of red, yellow, and green, wherein the red fixation ball is at the vertex of the training line;

[0008] After the red fixation ball is fixed on for a preset time, the two training lines are controlled to move to intersect at the yellow fixation ball;

[0009] After the yellow fixation ball is fixed on for the preset time, the two training lines are controlled to move to intersect at the green fixation ball, so that the green fixation ball is fixed on for the preset time;

[0010] The distance between the red fixation ball and the target object is equal to the distance between adjacent fixation balls.

[0011] As a further improvement of the present invention, after the green watching ball is watched for the preset time period, the method further comprises:

[0012] The two training lines are repeatedly controlled to move to the red fixation ball, the yellow fixation ball, and the green fixation ball to intersect each other, so that the red fixation ball, the yellow fixation ball, and the green fixation ball are fixed on for the preset time period respectively.

[0013] As a further improvement of the present invention, it also includes:

[0014] Control the two training lines to return to a position where the red fixation ball is an intersection node and control the two training lines to move closer to the target object at a first preset distance;

[0015] After the red fixation ball is fixed on for a preset time, the two training lines are controlled to move in sequence to intersect at the yellow fixation ball and the green fixation ball respectively, so that the yellow fixation ball and the green fixation ball are fixed on for the preset time respectively.

[0016] As a further improvement of the present invention, after sequentially controlling the two training lines to move to intersect at the yellow fixation ball and the green fixation ball respectively so that the yellow fixation ball and the green fixation ball are fixed on for a preset time, the operation further includes:

[0017] Repeat the control of the two training lines to return to the position with the red fixation ball as the intersection node and repeat the control of the two training lines to approach the target object at the first preset distance until the distance between the red fixation ball and the target object does not exceed the second preset distance.

[0018] As a further improvement of the present invention, the second preset distance does not exceed the first preset distance, and the first preset distance does not exceed the distance between adjacent fixation balls.

[0019] As a further improvement of the present invention, it also includes:

[0020] Before each fixation ball is fixed on, voice prompt information for prompting the user to fixate on the fixation ball of the target color is output to the target object.

[0021] As a further improvement of the present invention, it also includes:

[0022] Output eye protection science information to the target object.

[0023] In a second aspect, the present invention provides an anti-squinting control system for a mixed reality head display, comprising: a generating unit, in response to a target input, forming two training lines that intersect at a vertex, each training line having three-color gaze balls that are equidistantly arranged in the order of red, yellow, and green, wherein the red gaze ball is at the vertex of the training line;

[0024] A first control unit is used to control the two training lines to move to intersect at the yellow gaze ball after the red gaze ball has been gazed at for a preset time, and the distance between the red gaze ball and the target object is equal to the distance between adjacent gaze balls;

[0025] The second control unit is used for controlling the two training lines to move to intersect at the green fixation ball after the yellow fixation ball is fixed on for the preset time, so that the green fixation ball is fixed on for the preset time.

[0026] In a third aspect, the present invention provides a terminal device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the method described in the first aspect.

[0027] In a fourth aspect, the present invention provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the steps of the method described in the second aspect are implemented.

[0028] The beneficial effects of the present invention are:

[0029] The anti-strabismus control method for a mixed reality head display of the present invention first responds to the target input to form two training lines, both of which have three-color gaze balls arranged equidistantly in the order of red, yellow, and green, and intersect at the vertex, so that the user gazes at the red gaze ball at the vertex for a preset time, and then controls the two training lines to move to the yellow gaze ball to intersect, and then controls the user to gaze at the yellow gaze ball for a preset time, and then controls the two training lines to move to the green gaze ball to intersect, so that the user gazes at the green gaze ball for a preset time. In this way, the user can perform eye muscle training according to actual needs by wearing a head display equipped with an anti-strabismus control method to relieve visual fatigue and achieve the purpose of effectively preventing strabismus. The anti-strabismus control method of the present invention has a simple control process and is easy for users to operate, which solves the problem that the effect of preventing and treating eye strabismus cannot be achieved or the effect is not obvious by wearing glasses for a long time in the prior art. At the same time, since the anti-strabismus control method of the present invention only wears a head display equipped with an anti-strabismus control method for simulation training when the user needs training, it can meet the needs of some users who do not like to wear eye tools for a long time.

[0039] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0040] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] Embodiment 1:

[0042] Figure 1 The present invention is a schematic flow chart of an anti-squinting control method for a mixed reality head display, combined with Figure 1 and Figure 2 To illustrate, the method includes:

[0043] Step 102. In response to the target input, two training lines (training line L1 and training line L2) are formed that intersect at the vertex. Each training line has three-color fixation balls that are arranged equidistantly in the order of red, yellow, and green. Figure 1 As shown, the red fixation ball R is at the vertices of the training lines (training line L1 and training line L2).

[0044] Step 104. After the red gaze ball R is gazed at for a preset time, the two training lines are controlled to move to intersect at the yellow gaze ball Y, as shown in FIG. Figure 3 shown.

[0045] Step 106. After the yellow gaze ball Y is gazed at for a preset time, the two training lines are controlled to move to intersect at the green gaze ball G (eg Figure 4 As shown), the green gaze ball G is gazed for a preset time. The preset time involved in this embodiment can be configured as 5 to 10 seconds. Of course, the specific gaze time can be set according to actual training needs and is not limited to the scope defined in this embodiment.

[0046] The distance between the red gaze ball R and the target object 100 is equal to the distance between adjacent gaze balls. The distance between the red gaze ball R and the target object 100 is configured as Figure 2 The target object 100 looks at the red looking ball R at a looking distance, or is configured as Figure 3 or Figure 4The vertical distance between the target object 100 and the two red fixation balls R. The target object 100 is generally a user, and may also be other objects that can use the anti-squinting control method of this embodiment, which will not be described one by one.

[0047] It should be understood that the anti-strabismus control method for a mixed reality head display of this embodiment first responds to the target input to form two training lines, both of which have three-color gaze balls arranged equidistantly in the order of red, yellow, and green, and intersect at the vertex, so that the user gazes at the red gaze ball R at the vertex for a preset time, and then controls the two training lines to move to intersect at the yellow gaze ball Y, and then controls the user to gaze at the yellow gaze ball for a preset time, and then controls the two training lines to move to intersect at the green gaze ball G, so that the user gazes at the green gaze ball for a preset time. In this way, the user can perform eye muscle training (i.e., binocular vision training) according to actual needs by wearing a head display equipped with the anti-strabismus control method. Since binocular vision training utilizes the principle of visual perception learning, it can relieve visual fatigue and achieve the purpose of effectively preventing strabismus by training the user in binocular separation, interactive balance, etc., and the anti-strabismus control method of this embodiment has a simple control process and is easy for the user to operate, which solves the problem that the effect of preventing and treating eye strabismus cannot be achieved or the effect is not obvious by wearing glasses for a long time in the prior art. At the same time, since the anti-strabismus control method of this embodiment only requires the user to wear a head display equipped with the anti-strabismus control method for simulated training when the user needs training, it can meet the needs of some users who do not like to wear eye tools for a long time.

[0048] In the above embodiment, if Figure 5 As shown, the operation after step 106 further includes:

[0049] Step 108. Repeat the control of the two training lines to move to the red gaze ball, the yellow gaze ball, and the green gaze ball to intersect, so that the red gaze ball, the yellow gaze ball, and the green gaze ball are gazed for a preset time. That is, the training is repeated n times in the order of step 102, step 104, and step 106, and the time for gazing at different gaze balls each time can be a preset time. The value of n can be 2 to 10. Further, the value of n can be 3 to 5, and preferably, the value of n is 4.

[0050] like Figure 6 As shown, after step 106, the anti-squint control method for a mixed reality head display in this embodiment further includes:

[0051] Step 110: Control the two training lines to return to the position where the red fixation ball is the intersection node and control the two training lines to move closer to the target object 100 at a first preset distance.

[0052] Step 112. After the red fixation ball is fixed on for a preset time, the two training lines are controlled to move in sequence to intersect at the yellow fixation ball and the green fixation ball respectively, so that the yellow fixation ball and the green fixation ball are fixed on for the preset time respectively.

[0053] After the three-color gazing balls are gazed at for a preset time in sequence, the two training lines with the three-color gazing balls are simultaneously moved a certain distance toward the target object 100, and the training is continued again in the order of step 102, step 104, and step 106. It should be noted that step 110 and the corresponding step 112 can also be performed after step 108, that is, after the three-color gazing balls are gazed at for a preset time in sequence, the training is repeated n times in the order of step 102, step 104, and step 106, and after the training n times, the two training lines with the three-color gazing balls are simultaneously moved a certain distance toward the target object 100, and the training is continued n times in the order of step 102, step 104, and step 106.

[0054] Furthermore, the operations after step 112 also include:

[0055] Step 114. Repeat the control of the two training lines to restore to the position with the red gaze ball as the intersection node and repeat the control of the two training lines to move closer to the target object at the first preset distance until the distance between the red gaze ball and the target object does not exceed the second preset distance.

[0056] That is, after the yellow gaze ball and the green gaze ball have been stared at for a preset time, the two training lines are controlled again to return to the position with the red gaze ball as the intersection node, and the two training lines are controlled to continue to approach the target object at a first preset distance, so that after staring at the three-color gaze balls in the order of red, yellow and green for a preset time, the operation is repeated until the distance between the red gaze ball and the target object does not exceed the second preset distance.

[0057] Among them, the second preset distance does not exceed the first preset distance, and the first preset distance does not exceed the distance between adjacent gaze balls. Specifically, the first preset distance is configured to be 3 to 6 cm, the second preset distance is 1.5 to 2.5 cm, and further, the first preset distance is configured to be 5 cm, and the second preset distance is configured to be 2.5 cm. In the initial state, the distance between the red gaze ball and the target object, and the distance between adjacent gaze balls on each training line are any value between 20 and 50 cm. Further, the distance between the red gaze ball and the target object and the distance between adjacent gaze balls on each training line are configured to be 30 cm.

[0058] The anti-squint control method for a mixed reality head display of this embodiment also includes:

[0059] Before each fixation ball is fixed, a voice prompt message is output to the target object to prompt the user to fixate on the target color fixation ball. In order to prevent the user from being unclear or forgetting the steps in the anti-strabismus control method, before each time the user needs to fixate, the user is reminded by voice prompt which annotation ball to fixate on. Alternatively, when the anti-strabismus control method is actually used for training, the user may be prompted by voice prompt messages for matters that need to be emphasized (such as training with both eyes at the same time during training, or fixing the eyes with force when fixing the near fixation ball, etc.). Of course, the operation may also be performed by text reminders and other methods, which will not be described in detail one by one.

[0060] The anti-squinting control method for a mixed reality head display of this embodiment further includes: outputting eye protection science popularization information to the target object. The eye protection science popularization information mainly includes daily eye protection knowledge popularization, popularization of reading posture precautions, and popularization of precautions for watching electronic products.

[0061] In a specific embodiment, the anti-squint control method for a mixed reality head display mainly includes:

[0062] First, after starting the head display, enter the application menu, and click the application icon in the menu where the anti-strabismus control method software of this embodiment is installed to enter the training page. The page forms two training routes L1 and L2 that intersect at the vertex. Each training route has three-color gaze balls that are arranged equidistantly in the order of red, yellow, and green. The distance between the red gaze ball and the user (such as the tip of the nose or the center of the eyebrows or the center of the two eyes) and the distance between adjacent gaze balls are all configured to be 30 cm. The red gaze ball R is at the vertex of the training route, such as Figure 2 shown.

[0063] Secondly, after the red fixation ball is fixed for 5 seconds, the two training lines are controlled to move to intersect at the yellow fixation ball Y (e.g. Figure 3 As shown), and after the yellow fixation ball Y is fixed for 5 seconds, the two training lines are controlled to move to intersect at the green fixation ball G (as shown Figure 4 Then, the two training lines are repeatedly controlled to move to the red, yellow, and green gaze balls respectively, and the red, yellow, and green gaze balls are repeatedly gazed 3 to 5 times in order.

[0064] Finally, the two training lines are controlled to return to the position where the red fixation ball R is the intersection node and the two training lines are controlled to move 5 cm closer to the user, and then the two training lines are repeatedly controlled to move to the red fixation ball R, the yellow fixation ball Y, and the green fixation ball G to intersect, so that the red fixation ball, the yellow fixation ball, and the green fixation ball are repeatedly fixed in sequence for 3 to 5 times. Then, the two training lines are repeatedly controlled to return to the position where the red fixation ball is the intersection node and the two training lines are repeatedly controlled to move 5 cm closer to the user again, until the distance between the red fixation ball and the user does not exceed 2 cm.

[0065] In this way, the user can perform eye muscle training by wearing a head mounted with the anti-strabismus control method to relieve visual fatigue and achieve the purpose of effectively preventing strabismus. The anti-strabismus control method of this embodiment has a simple control process and is easy for the user to operate, which solves the problem in the prior art that the effect of preventing and treating eye strabismus cannot be achieved or the effect is not obvious by wearing glasses for a long time. At the same time, since the anti-strabismus control method of this embodiment only requires the user to wear the head mounted with the anti-strabismus control method for simulated training when training is needed, it can meet the needs of some users who do not like to wear eye tools for a long time.

[0066] In addition, the "three-color gaze ball" involved in this embodiment can also be configured with other colors, not limited to the color range specified in this embodiment, as long as the spectrum color is satisfied, otherwise the color cast will easily cause visual fatigue to the user. The "training line L1" and "training line L2" involved in this embodiment are both straight lines or approximate straight lines.

[0067] Embodiment 2:

[0068] like Figure 8 As shown, the present embodiment further provides an anti-squint control system 800 for a mixed reality head display (hereinafter referred to as the "anti-squint control system" or "system"), comprising: a generating unit 801, which forms two training lines that intersect at the vertex in response to a target input, each training line having three-color gaze balls arranged equidistantly in the order of red, yellow, and green, wherein the red gaze ball R is at the vertex of the training line; a first control unit 802, which is used to control the two training lines to move to intersect at the yellow gaze ball Y after the red gaze ball is gazed for a preset time, and control the two training lines to move to intersect at the green gaze ball G after the yellow gaze ball is gazed for a preset time, so that the green gaze ball is gazed for a preset time. In this embodiment, the distance between the red gaze ball and the target object is equal to the distance between adjacent gaze balls.

[0069] The system 100 of this embodiment further includes: a second control unit 803, which is used to control the voice prompt unit 804 to output voice prompt information to the target object 100 when or before the three-color gaze ball is gazed, based on the two training lines that intersect at the vertex formed by the generation unit 801, so that the target object 100 is trained based on the voice prompt information. The system of this embodiment further includes: a popular science unit 805, which is used to output popular science information on eye protection to the target object 100 in a controlled manner.

[0070] It should be understood that the anti-strabismus control system 100 for a mixed reality head display of this embodiment forms two training lines each having three-color gaze balls arranged equidistantly in the order of red, yellow, and green and intersecting at the vertex through a generating unit in response to a target input, so that the first control unit controls the two training lines to move to the yellow gaze ball and intersect after the user gazes at the red gaze ball at the vertex for a preset time, and then the second control unit controls the two training lines to move to the green gaze ball and intersect after the user gazes at the yellow gaze ball for a preset time, so that the user gazes at the green gaze ball for a preset time. In this way, the user can train according to actual needs by wearing a head display equipped with an anti-strabismus control system to relieve visual fatigue and achieve the purpose of effectively preventing strabismus. The control process of the anti-strabismus control system of this embodiment is simple, and the user is easy to operate, which solves the problem that the effect of preventing and treating eye strabismus cannot be achieved or the effect is not obvious by wearing glasses for a long time in the prior art. At the same time, since the anti-strabismus control system of this embodiment only wears a head display equipped with an anti-strabismus control method for simulation training when the user needs training, it can meet the needs of some users who do not like to wear eye tools for a long time.
