[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0062] Before further describing the embodiments of the present disclosure in detail, the nouns and terms involved in the embodiments of the present disclosure are described. The nouns and terms involved in the embodiments of the present disclosure are subject to the following interpretations:

[0063] Naked-eye 3D refers to the ability to see 3D images with a sense of three-dimensionality with the naked eye without the aid of any special glasses or other auxiliary equipment. Naked-eye 3D technology mainly uses the parallax principle of the human eye. Because the two eyes are in different positions, there are certain differences in the images seen. Naked-eye 3D technology projects images of different perspectives into the left and right eyes of a person through special screen design or optical devices, thereby forming a sense of three-dimensionality in the brain. Common naked-eye 3D technologies include parallax barrier technology and cylindrical lens technology.

[0064] The parallax principle of the human eye refers to the fact that due to the different positions of the two eyes, when observing the same object, there will be differences in perspective, thus forming different images on the retina. The brain processes and fuses these two slightly different images to produce a sense of three-dimensionality and depth.

[0065] Positive parallax: Parallax when the left view of an object is on the left and the right view is on the right on the display screen. When viewing an object with positive parallax, the perceived image of the object is behind the display screen.

[0066] Negative parallax: Parallax when the left view of an object on the display screen is on the right and the right view is on the left. When viewing an object with negative parallax, the perceived object is in front of the display screen.

[0067] The stereoscopic visual effect can provide images with parallax to each eye of a person, which are then synthesized by the brain to produce a stereoscopic feeling. This is recognized as one of the main mechanisms for forming stereoscopic vision. For example, computer equipment reproduces image signals with parallax information as images with parallax, thus giving the observer stereoscopic vision.

[0068] The above is a detailed introduction to the relevant terms.

[0069] Before introducing the visual fatigue relief method, device, computer equipment and storage medium provided by the embodiments of the present application, the existing technical problems are first described:

[0070] With the popularization of smart electronic devices such as computers and mobile phones, people use their eyes to look at display screens for a long time, that is, watching a two-dimensional plane for a long time makes the human eyes maintain a fixed viewing distance for a long time, which can easily lead to visual fatigue and even cause the human eye's lens adjustment ability to deteriorate, resulting in symptoms of myopia.

[0071] There are many ways to relieve visual fatigue, such as using eye drops, but there are some strong irritating ingredients in eye drops, which are very irritating to the eyes and can easily cause discomfort. Another example is to adjust the lens by looking far away outdoors, so as to relieve visual fatigue, but in urban environments, it is often impossible to look far away due to dense buildings.

[0072] Therefore, in modern society, how to relieve human eye fatigue has become a technical problem that needs to be solved urgently.

[0073] In order to solve the above technical problems, in an embodiment of the present application, a three-dimensional virtual picture is displayed on a naked-eye three-dimensional display screen. The three-dimensional virtual picture includes multiple three-dimensional virtual sub-objects. The multiple three-dimensional virtual sub-objects can be dynamically displayed with different depths of field according to display parameters, thereby achieving a floating display effect of the three-dimensional virtual sub-objects approaching or moving away from the human eye. In this way, when the human eye views the three-dimensional virtual sub-objects, the viewing distance will change, thereby alleviating eye fatigue caused by a fixed viewing distance.

[0074] See also Figure 1 , Figure 1 1 is a schematic diagram of a system framework corresponding to the method for alleviating visual fatigue provided in the embodiment of the present application. The method for alleviating visual fatigue provided in the embodiment of the present application can be applied to the system framework.

[0075] Please refer to Figure 1 , Figure 1 1 is a system architecture diagram used by the visual fatigue relief method provided in the embodiment of the present application, which includes a terminal 140, an Internet 130, a gateway 120, a server 110, and the like.

[0076] The terminal 140 or the server 110 may be a device for executing the method for alleviating visual fatigue.

[0077] The terminal 140 includes but is not limited to mobile phones, computers, intelligent voice interaction devices, smart home appliances, vehicle-mounted terminals, aircraft, etc. The embodiments of the present application can be applied to various scenarios, including but not limited to cloud office, enterprise management, etc. In addition, it can be a single device or a collection of multiple devices. For example, multiple desktop computers are interconnected through a local area network, share a display, etc. to work together, and together constitute a terminal 140. The terminal 140 can communicate with the Internet 130 in a wired or wireless manner to exchange data.

[0078] The server 110 refers to a computer system that can provide certain services to the terminal 140. Compared with the ordinary terminal 140, the server 110 has higher requirements in terms of stability, security, performance, etc. The server 110 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms.

[0079] The gateway 120 is also called an internetwork connector or a protocol converter. The gateway realizes network interconnection at the transport layer and is a computer system or device that acts as a converter. The gateway is a translator between two systems that use different communication protocols, data formats or languages, or even completely different architectures. At the same time, the gateway can also provide filtering and security functions. The message sent by the terminal 140 to the server 110 must be sent to the corresponding server 110 through the gateway 120. The message sent by the server 110 to the terminal 140 must also be sent to the corresponding terminal 140 through the gateway 120.

[0080] The method for alleviating visual fatigue in the embodiment of the present application can be applied to a variety of scenarios, such as alleviating visual fatigue, vision training, vision recovery, etc. The scenario to which the method for alleviating visual fatigue in the present application is applied is not limited here.

[0081] See also Figure 2 , Figure 2 It is a schematic diagram of a scene corresponding to the method for alleviating visual fatigue provided in an embodiment of the present application.

[0082] exist Figure 2 In the scene shown, the naked eye 3D display screen can display a 3D virtual picture, which includes multiple 3D virtual sub-objects. Multiple 3D virtual sub-objects can form a 3D virtual object for display. For example, the 3D virtual object can be quicksand, water vapor, fire, meteors, etc. Assuming that the 3D virtual object is quicksand, the 3D virtual sub-object can be sand grains in the quicksand. Assuming that the 3D virtual object is water vapor, the 3D virtual sub-object can be water droplets in the water vapor.

[0083] The three-dimensional virtual sub-objects correspond to display parameters. For example, each three-dimensional virtual sub-object corresponds to display parameters, and the display status of each three-dimensional virtual sub-object when displayed on the naked-eye three-dimensional display screen can be controlled according to the display parameters. For example, the display parameters include the display area of ​​each three-dimensional virtual sub-object, and each three-dimensional virtual sub-object can be controlled to be displayed in three dimensions in the naked-eye three-dimensional display screen according to the display area. For example, the display parameters include the visual screen-out distance of each three-dimensional virtual sub-object, and each three-dimensional virtual sub-object can be controlled to be displayed in three dimensions in the naked-eye three-dimensional display screen according to the visual screen-out distance.

[0084] After setting the display parameters, each 3D virtual sub-object can be controlled to be dynamically displayed in a 3D space corresponding to the 3D virtual screen according to the display parameters with a variety of different depths of field, so as to achieve a floating display effect of the 3D virtual sub-object approaching or moving away from the human eye. In this way, by displaying a 3D virtual screen on a naked-eye 3D display screen, the 3D virtual screen includes multiple 3D virtual sub-objects, and the multiple 3D virtual sub-objects can be dynamically displayed with different depths of field according to the display parameters, thereby achieving a floating display effect of the 3D virtual sub-object approaching or moving away from the human eye, so that when the human eye views the 3D virtual sub-object, the viewing distance will change, thereby alleviating eye fatigue caused by a fixed viewing distance.

[0085] like Figure 2 As shown, the PP direction is the depth of field direction, and multiple three-dimensional virtual sub-objects can be dynamically displayed with different depths of field in the three-dimensional space corresponding to the three-dimensional virtual screen. For example, when the depth of field corresponding to the three-dimensional virtual sub-object is large, when the human eye views the three-dimensional virtual sub-object, positive parallax will be formed in the human eye. At this time, when the three-dimensional virtual sub-object is displayed in the three-dimensional virtual screen, the three-dimensional virtual sub-object is behind the plane where the naked eye three-dimensional display screen is located, that is, on the side away from the human eye. For example, when the depth of field corresponding to the three-dimensional virtual sub-object is small, when the human eye views the three-dimensional virtual sub-object, negative parallax will be formed in the human eye. When the three-dimensional virtual sub-object is displayed in the three-dimensional virtual screen, the three-dimensional virtual sub-object is in front of the plane where the naked eye three-dimensional display screen is located, that is, on the side close to the human eye.

[0086] Multiple three-dimensional virtual sub-objects continuously update the depth of field in the three-dimensional virtual screen, thereby achieving a floating display effect of the three-dimensional virtual sub-objects approaching or moving away from the human eye. Taking quicksand composed of multiple three-dimensional virtual sub-objects as an example, the quicksand flows into the human eye, or the quicksand flows out of the human eye to a distance, thus forming a flowing display effect. When watching, the human eye will adjust the viewing distance from far to near or from near to far as the quicksand flows, thereby adjusting the lens of the human eye and alleviating eye fatigue caused by fixed viewing distance.

[0087] The above is a brief description of the method for relieving eyestrain provided in the embodiment of the present application from the perspective of relieving eyestrain. In fact, the method for relieving eyestrain in the present application can also be used in scenarios such as vision training and vision restoration, without limitation.

[0088] The following is a detailed description of the visual fatigue relief method, device, computer equipment and storage medium provided in the embodiments of the present application.

[0089] The embodiments of the present application provide a method, device, computer equipment and storage medium for alleviating visual fatigue. Specifically, the embodiments of the present application will be described from the dimension of a visual fatigue alleviating device, which can be integrated in a computer device, which can be a server or a terminal or other device. Among them, the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. Among them, the terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a vehicle-mounted terminal, an intelligent voice interaction device, etc., but is not limited to this. The embodiments of the present application can be applied to various scenarios, including but not limited to scenarios for alleviating visual fatigue.

[0090] See also Figure 3 , Figure 3 : is a flow chart of a method for alleviating visual fatigue provided by an embodiment of the present application. The method for alleviating visual fatigue may include the following steps:

[0091] Step 210: displaying a 3D virtual picture on the naked eye 3D display screen, wherein a plurality of 3D virtual sub-objects are displayed on the 3D virtual picture, and the volume of each 3D virtual sub-object is smaller than a preset volume threshold;

[0092] Step 220: Determine the display parameters corresponding to each 3D virtual sub-object when it is displayed on the naked eye 3D display screen;

[0093] Step 230: Control each 3D virtual sub-object to be dynamically displayed in a 3D space corresponding to the 3D virtual screen at a plurality of different depths of field according to the display parameters, so as to achieve a floating display effect of the 3D virtual sub-object approaching or moving away from the human eye.

[0094] Steps 210 to 230 will be described in detail below.

[0095] In step 210, a 3D virtual picture is displayed on a naked-eye 3D display screen, and a plurality of 3D virtual sub-objects are displayed on the 3D virtual picture, wherein the volume of each 3D virtual sub-object is smaller than a preset volume threshold.

[0096] In an embodiment of the present application, the naked-eye 3D display screen can display a 3D virtual image, which can be viewed by the human eye without any professional equipment. The naked-eye 3D display screen can simultaneously display the left view and the right view of the 3D virtualized image. By observing the left view and the right view with the human eye, positive parallax or negative parallax will be formed in the human eye, thereby realizing the viewing of the 3D virtual image.

[0097] In some embodiments, in a three-dimensional virtual screen, multiple three-dimensional virtual sub-objects can be displayed, and the volume of each three-dimensional virtual sub-object is less than a preset volume threshold. It is understandable that the larger the volume of the three-dimensional virtual sub-object, the stronger the stimulation to the human eye when the three-dimensional virtual sub-object moves in the three-dimensional space corresponding to the three-dimensional virtual screen and changes the depth of field, such as the feeling of a giant object impacting the human eye, which will have a strong stimulation to the human eye and cause physiological discomfort. Taking this problem into consideration, in the present application, by making the volume of each three-dimensional virtual sub-object smaller than the preset volume threshold, the stimulation to the human eye caused by the change of the depth of field when the three-dimensional virtual sub-object moves in the three-dimensional space can be reduced, thereby more comfortably relieving the visual fatigue of the human eye.

[0098] Among them, the three-dimensional virtual screen generates at least one hundred three-dimensional virtual sub-objects within a preset time. For example, at least one hundred three-dimensional virtual sub-objects are generated and displayed in the three-dimensional virtual screen within one minute. It can be seen from the above scene description that multiple three-dimensional virtual sub-objects can form three-dimensional virtual objects of different scenes such as quicksand, water vapor, fire, and meteors. If a certain scale of quicksand, water vapor, fire, meteors, etc. is to be formed, the number of three-dimensional virtual sub-objects needs to be set to more than one hundred in this application, so that multiple three-dimensional virtual sub-objects can constitute a three-dimensional virtual object, thereby displaying a certain scene of quicksand, water vapor, fire, meteors, etc. in the three-dimensional virtual screen.

[0099] In the embodiment of the present application, multiple types of 3D virtual sub-objects can be pre-set, and different 3D virtual sub-objects can form different 3D virtual objects, for example, the 3D virtual object can be quicksand, water vapor, fire, meteors, etc. Assuming that the 3D virtual object is quicksand, the 3D virtual sub-object can be sand grains in the quicksand. Assuming that the 3D virtual object is water vapor, the 3D virtual sub-object can be water droplets in the water vapor.

[0100] In some embodiments, before determining the display parameters corresponding to each 3D virtual sub-object when displayed on a naked-eye 3D display screen, the process includes:

[0101] (1.1) Pre-displaying multiple three-dimensional virtual sub-objects of different types in a three-dimensional virtual screen;

[0102] (1.2) obtaining a change speed of the pupil diameter of a human eye when displaying multiple three-dimensional virtual sub-objects of each type;

[0103] (1.3) Determine the multiple three-dimensional virtual sub-objects of the type corresponding to the highest change speed as the multiple three-dimensional virtual sub-objects displayed on the naked-eye three-dimensional display screen.

[0104] Among them, in the three-dimensional virtual screen, multiple three-dimensional virtual sub-objects of different types can be pre-displayed, and multiple three-dimensional virtual sub-objects of each type can constitute a three-dimensional virtual object of a scene, such as three-dimensional virtual objects corresponding to scenes such as quicksand, water vapor, fire, and meteors.

[0105] It is understandable that different users have different sensitivities to different scenes. For example, some users' eyes are more sensitive to scenes of quicksand, while some users are more sensitive to scenes of meteors. Therefore, multiple three-dimensional virtual sub-objects of different types can be pre-displayed in the three-dimensional virtual screen to achieve the display of different scenes, and then determine which scene the user is more sensitive to, and then determine the multiple three-dimensional virtual sub-objects corresponding to the more sensitive scene as the multiple three-dimensional virtual sub-objects displayed on the naked-eye three-dimensional display screen.

[0106] Specifically, when multiple three-dimensional virtual sub-objects of each type are pre-displayed in the three-dimensional virtual screen, for example, multiple three-dimensional virtual sub-objects of each type are controlled to be pre-displayed in the three-dimensional virtual screen according to default display parameters, such as showing floating display effects of quicksand, water vapor, fire, meteors and the like.

[0107] When displaying multiple three-dimensional virtual sub-objects of each type, the speed of change of the pupil diameter of the human eye when displaying the multiple three-dimensional virtual sub-objects of each type can be obtained. The speed of change of the pupil diameter of the human eye can reflect the sensitivity of the human eye to the multiple three-dimensional virtual sub-objects of each type when they are displayed in advance. For example, taking the type corresponding to the quicksand scene as an example, when the multiple three-dimensional virtual sub-objects are displayed in advance, they can show the effect of quicksand flowing toward or away from the human eye. At this time, the speed of change of the pupil diameter of the human eye can be obtained, such as the speed at which the pupil diameter increases or decreases. Specifically, the user's eyes can be continuously photographed by a camera, and then the speed of change of the pupil diameter of the human eye can be analyzed through the pupil diameter of the human eye at different time points.

[0108] It can be understood that if the pupil diameter of the human eye changes faster, it means that the human eye is more sensitive to a certain scene, and multiple three-dimensional virtual sub-objects of the type corresponding to the highest change speed can be determined as multiple three-dimensional virtual sub-objects displayed on the naked-eye three-dimensional display screen. In the subsequent process, multiple three-dimensional virtual sub-objects of this type can be displayed.

[0109] The advantage of doing this is that by pre-displaying multiple types of multiple three-dimensional virtual sub-objects, multiple three-dimensional virtual sub-objects of the type that the user's eyes are most sensitive to can be selected for continued naked-eye three-dimensional display in the subsequent process, thereby achieving more effective stimulation to the human eye and effectively alleviating visual fatigue.

[0110] In step 220, display parameters corresponding to each 3D virtual sub-object when displayed on a naked-eye 3D display screen are determined.

[0111] Among multiple three-dimensional virtual sub-objects, each three-dimensional virtual sub-object has corresponding display parameters when displayed on a naked-eye three-dimensional display screen. The display parameters may include multiple parameters. The display parameters may be used to control the display of multiple three-dimensional virtual sub-objects on a naked-eye three-dimensional display screen. It may also be understood that the display parameters control the display of multiple three-dimensional virtual sub-objects in a three-dimensional space corresponding to a three-dimensional virtual screen.

[0112] In some embodiments, the display parameters include at least a target visual screen-out distance corresponding to each 3D virtual sub-object when displayed on a naked-eye 3D display screen, and determining the display parameters corresponding to each 3D virtual sub-object when displayed on a naked-eye 3D display screen includes:

[0113] (1.1) Determine the viewing distance between the human eye and the naked eye 3D display screen;

[0114] (1.2) When the viewing distance is within the preset viewing distance range, multiply the viewing distance by the preset proportional coefficient to obtain the preset screen exit distance threshold;

[0115] (1.3) Determine a target visual off-screen distance according to a preset off-screen distance threshold, and generate corresponding display parameters for each three-dimensional virtual sub-object when displayed on a naked-eye three-dimensional display screen according to the target visual off-screen distance. The target visual off-screen distance is the minimum visual off-screen distance for each three-dimensional virtual sub-object.

[0116] Among them, see Figure 4 , Figure 4 is a schematic diagram of the viewing distance provided by the embodiment of the present application. The distance between the human eye and the plane of the naked eye 3D display screen can be obtained and determined as the viewing distance between the human eye and the naked eye 3D display screen, such as Figure 4 As shown, the viewing distance may be D.

[0117] When the viewing distance is within the preset viewing distance range, for example, within 2 meters, the viewing distance can be multiplied by the preset proportional coefficient to obtain the preset screen-out distance threshold. The preset proportional coefficient can be a specific coefficient or multiple specific coefficients. For example, if the preset proportional coefficient is 5%, then the viewing distance is multiplied by 5% to obtain the preset screen-out distance threshold.

[0118] Then, the target visual off-screen distance is determined according to the preset off-screen distance threshold. For example, the preset off-screen distance threshold is directly determined as the target visual off-screen distance. The target visual off-screen distance is the minimum visual off-screen distance of each three-dimensional virtual sub-object. That is to say, if each three-dimensional virtual sub-object is to appear outside the naked-eye display screen during three-dimensional display, then the emerging distance is at least the minimum visual off-screen distance. The emerging distance can be understood as the distance of the three-dimensional virtual sub-object in three-dimensional space perpendicular to the plane where the naked-eye three-dimensional display screen is located.

[0119] Please also read Figure 5 , Figure 5 It is a schematic diagram of the target visual screen distance provided in an embodiment of the present application.

[0120] The display parameters corresponding to each 3D virtual sub-object when displayed on the naked eye 3D display screen can be generated according to the target visual screen distance, such as Figure 5 As shown, the target visual off-screen distance is S, and the corresponding visual off-screen distance of each three-dimensional virtual sub-object when displayed on the naked-eye three-dimensional display screen can be controlled to be greater than or equal to the target visual off-screen distance S, and then the visual off-screen distance corresponding to each three-dimensional virtual sub-object is used as one of the display parameters.

[0121] The advantage of doing this is that the visual off-screen distance of each three-dimensional virtual sub-object can be controlled to be above the target visual off-screen distance. This can enhance the stereoscopic effect of multiple three-dimensional virtual sub-objects when displayed, increase the degree of stimulation to the human eye, and help the human eye adjust the viewing distance to relieve visual fatigue.

[0122] In some embodiments, the display parameters include at least a display area corresponding to each 3D virtual sub-object when displayed on a naked-eye 3D display screen, and determining the display parameters corresponding to each 3D virtual sub-object when displayed on a naked-eye 3D display screen includes:

[0123] (2.1) Determine the total display area of ​​the naked eye 3D display screen;

[0124] (2.2) determining the cross-sectional area of ​​each three-dimensional virtual sub-object parallel to the naked-eye three-dimensional display screen;

[0125] (2.3) Determine the cross-sectional area as the display area of ​​each three-dimensional virtual sub-object, and generate corresponding display parameters of each three-dimensional virtual sub-object when displayed on a naked-eye three-dimensional display screen according to the display area, wherein the display area is within one thousandth of the total display area.

[0126] Among them, the total display area of ​​the naked-eye 3D display screen is determined first, and then the cross-sectional area of ​​each 3D virtual sub-object parallel to the naked-eye 3D display screen is determined. For example, each 3D virtual sub-object can be cut, and there will be a cross-section after cutting. The cross-section is parallel to the plane of the naked-eye 3D display screen. The area of ​​the cross-section is determined as the cross-sectional area, and then the cross-sectional area is determined as the display area of ​​each 3D virtual sub-object. The display area is within one thousandth of the total display area. Finally, the display parameters corresponding to each 3D virtual sub-object when displayed in the naked-eye 3D display screen are generated according to the display area, that is, the display area is used as one of the display parameters.

[0127] The advantage of doing this is that the size of each 3D virtual sub-object when displayed on a naked-eye 3D display screen can be reasonably controlled to avoid excessive stimulation to the human eye and discomfort caused by the 3D virtual sub-object being too large.

[0128] In some embodiments, the display parameters include at least a flow speed of each 3D virtual sub-object in a 3D space corresponding to the 3D virtual screen when the 3D virtual sub-object is displayed on the naked eye 3D display screen, and determining the display parameters corresponding to each 3D virtual sub-object when the 3D virtual sub-object is displayed on the naked eye 3D display screen includes:

[0129] (3.1) determining a first velocity of each 3D virtual sub-object in a depth direction perpendicular to the naked eye 3D display screen in the 3D space;

[0130] (3.2) Determine the flow speed corresponding to each three-dimensional virtual sub-object in the three-dimensional space according to the first speed, and generate display parameters corresponding to each three-dimensional virtual sub-object when displayed on the naked-eye three-dimensional display screen according to the flow speed.

[0131] Among them, see Figure 6 , Figure 6 It is a schematic diagram of a three-dimensional space provided in an embodiment of the present application.

[0132] The three-dimensional virtual picture corresponds to a three-dimensional space, in which a three-dimensional coordinate system can be established, in which the plane formed by the X-axis and the Y-axis is parallel to the plane of the naked-eye three-dimensional display screen, the plane formed by the X-axis and the Z-axis is perpendicular to the plane of the naked-eye three-dimensional display screen, and the plane formed by the Y-axis and the Z-axis is perpendicular to the plane of the naked-eye three-dimensional display screen.

[0133] The first speed of each 3D virtual sub-object in the depth direction perpendicular to the naked-eye 3D display screen in the 3D space, that is, the first speed in the Z-axis direction, may be determined.

[0134] Then, the flow speed corresponding to each 3D virtual sub-object in the 3D space is determined according to the first speed. For example, the first speed of the 3D virtual sub-object can be directly determined as the flow speed corresponding to the 3D virtual sub-object in the 3D space.

[0135] For another example, the second speed of each three-dimensional virtual sub-object in the X-axis direction in the three-dimensional space and the third speed of each three-dimensional virtual sub-object in the Y-axis direction in the three-dimensional space can be obtained, and finally a target speed is generated according to the first speed, the second speed and the third speed, and the target speed is determined as the corresponding flow speed of each three-dimensional virtual sub-object in the three-dimensional space.

[0136] Finally, the display parameters corresponding to each three-dimensional virtual sub-object when displayed on the naked-eye three-dimensional display screen are generated according to the flow speed, that is, the flow speed is used as one of the display parameters.

[0137] The advantage of doing this is that the movement of each 3D virtual sub-object in the 3D space can be controlled by the flow speed. When multiple 3D virtual sub-objects are displayed on the naked-eye 3D display screen, the depth of field of the multiple 3D virtual sub-objects changes due to the movement, thereby forming a floating display effect of multiple 3D virtual sub-objects close to or far away from the human eye. In this way, when the human eye views the 3D virtual sub-objects, the viewing distance will change, thereby alleviating eye fatigue caused by a fixed viewing distance.

[0138] In some embodiments, the display parameters corresponding to each three-dimensional virtual sub-object may also include a motion cycle, where the three-dimensional virtual sub-object approaches the human eye from a distance, and then moves away from the human eye to a distance, constituting a motion cycle. For example, the motion cycle is within a frequency range, such as the frequency range of 0.1 Hz to 10 Hz, that is, the slowest motion cycle can occur once every 10 seconds, so the flow speed of each three-dimensional virtual sub-object is slower, and the fastest motion cycle can occur 10 times per second, so the flow speed of each three-dimensional virtual sub-object is faster. In the present application, the motion cycle corresponding to each three-dimensional virtual sub-object can be set within the frequency range of 0.1 Hz to 10 Hz, and the display parameters corresponding to each three-dimensional virtual sub-object when displayed on the naked eye three-dimensional display screen are generated according to the motion cycle.

[0139] It should be noted that, in the present application, the display parameters corresponding to each three-dimensional virtual sub-object when displayed on a naked-eye three-dimensional display screen may also include other types of display parameters. The above are just examples of several of the display parameters and are not limited to this.

[0140] In step 230, each 3D virtual sub-object is controlled to be dynamically displayed in a 3D space corresponding to the 3D virtual screen at a plurality of different depths of field according to the display parameters, so as to achieve a floating display effect of the 3D virtual sub-object approaching or moving away from the human eye.

[0141] After determining the display parameters corresponding to each 3D virtual sub-object, each 3D virtual sub-object can be controlled to be dynamically displayed in a 3D space corresponding to the 3D virtual screen with a variety of different depths of field according to the display parameters. For example, each 3D virtual sub-object can be controlled to be far away from or close to the human eye according to the display parameters, so that when multiple 3D virtual sub-objects are moving, a floating display effect is formed. For example, multiple 3D virtual sub-objects can form a quicksand scene, and the quicksand can be displayed far away from or close to the human eye, thereby forming a floating display effect. In this way, when the human eye views the 3D virtual sub-object, the viewing distance will change, thereby alleviating the eye fatigue caused by a fixed viewing distance.

[0142] In some embodiments, each 3D virtual sub-object is controlled to be dynamically displayed in a 3D space corresponding to the 3D virtual screen at a plurality of different depths of field according to display parameters, wherein the volume of the 3D virtual sub-object changes dynamically according to the depth of field.

[0143] For example, when it is determined based on the depth of field that each three-dimensional virtual sub-object is close to the human eye, the volume of each three-dimensional virtual sub-object is increased according to the depth of field corresponding to each three-dimensional virtual sub-object; when it is determined based on the depth of field that each three-dimensional virtual sub-object is far away from the human eye, the volume of each three-dimensional virtual sub-object is reduced according to the depth of field corresponding to each three-dimensional virtual sub-object.

[0144] In this way, when the depth of field corresponding to each three-dimensional virtual sub-object changes, its volume can be adjusted, thereby further increasing the degree of stimulation to the human eye, so that the human eye can pay attention to the depth of field changes of multiple three-dimensional virtual sub-objects. In this way, when the human eye views the three-dimensional virtual sub-objects, the viewing distance will change, thereby alleviating eye fatigue caused by a fixed viewing distance.

[0145] In some embodiments, after controlling each 3D virtual sub-object to be dynamically displayed in a 3D space corresponding to the 3D virtual picture at a plurality of different depths of field according to the display parameters, the method further includes:

[0146] (1.1) Obtaining the wetness of human eyes and / or blinking frequency;

[0147] (1.2) Determine the stimulation value of the human eye based on the wetness and / or blinking frequency;

[0148] (1.3) when the stimulus value is lower than a preset stimulus value, adjusting the appearance of at least part of the three-dimensional virtual sub-object, and / or increasing the volume of at least part of the three-dimensional virtual sub-object, to obtain an adjusted three-dimensional virtual sub-object;

[0149] (1.4) According to the display parameters, the adjusted three-dimensional virtual sub-object is dynamically displayed in a three-dimensional space corresponding to the three-dimensional virtual screen at a plurality of different depths of field, so as to achieve a floating display effect in which the adjusted three-dimensional virtual sub-object approaches or moves away from the human eye.

[0150] Among them, after controlling each three-dimensional virtual sub-object to be dynamically displayed with multiple depths of field in the three-dimensional space corresponding to the three-dimensional virtual screen according to the display parameters, the wetness and / or blinking frequency of the human eye can be obtained, and the stimulation value of the human eye can be determined based on the wetness and / or blinking frequency.

[0151] For example, the higher the wetness and / or blinking frequency of the human eye, the more sensitive the human eye is to the dynamically displayed three-dimensional virtual sub-object, and the higher the corresponding stimulation value of the human eye. A mapping relationship between the wetness and / or blinking frequency of the human eye and the stimulation degree of the human eye can be established in advance. After the wetness and / or blinking frequency of the human eye is obtained, the stimulation value of the human eye can be found through the mapping relationship and the wetness and / or blinking frequency of the human eye.

[0152] When the stimulation value is lower than the preset stimulation value, it means that the dynamic display of multiple three-dimensional virtual sub-objects at this time has a low stimulation degree to the human eye and cannot effectively relieve the visual fatigue of the human eye. At this time, the appearance of at least part of the three-dimensional virtual sub-objects can be adjusted, and / or the volume of at least part of the three-dimensional virtual sub-objects can be increased, so as to change the three-dimensional virtual sub-objects, thereby enhancing the stimulation degree of the changed three-dimensional virtual sub-objects to the human eye, so as to strengthen the stimulation of the three-dimensional virtual sub-objects to the human eye, so that the human eye can pay attention to the depth of field changes of multiple three-dimensional virtual sub-objects, so that when the human eye views the three-dimensional virtual sub-objects, the viewing distance will change, thereby alleviating the eye fatigue caused by the fixed viewing distance.

[0153] Finally, the adjusted 3D virtual sub-object is dynamically displayed in a 3D space corresponding to the 3D virtual screen at a variety of depths of field according to the display parameters, so as to achieve a floating display effect of the adjusted 3D virtual sub-object approaching or moving away from the human eye.

[0154] Please also read Figure 7 , Figure 7 is another schematic diagram of a scenario for alleviating visual fatigue provided by an embodiment of the present application, wherein Figure 7 The 3D virtual sub-objects in Figure 5 The three-dimensional virtual sub-object in is a three-dimensional virtual sub-object after the shape is changed, that is, the original shape of the three-dimensional virtual sub-object is a star, and after the shape is changed, the shape of the three-dimensional virtual sub-object becomes a polygon.

[0155] The advantage of doing this is that by changing the shapes and / or volumes of multiple three-dimensional virtual sub-objects, the stimulation of multiple three-dimensional virtual sub-objects to the human eye can be enhanced, so that the human eye can pay attention to the depth changes of multiple three-dimensional virtual sub-objects. In this way, when the human eye views the three-dimensional virtual sub-objects, the viewing distance will change, thereby alleviating eye fatigue caused by a fixed viewing distance.

[0156] In some embodiments, after controlling each 3D virtual sub-object to be dynamically displayed in a 3D space corresponding to the 3D virtual picture at a plurality of different depths of field according to the display parameters, the method further includes:

[0157] (2.1) Obtaining the adjustment parameters corresponding to each three-dimensional virtual sub-object;

[0158] (2.2) adjusting the display parameters of each three-dimensional virtual sub-object according to the adjustment parameters to obtain updated display parameters;

[0159] (2.3) Controlling each 3D virtual sub-object to be dynamically displayed in a 3D space corresponding to the 3D virtual screen at a plurality of different depths of field according to the updated display parameters, so as to achieve a floating display effect of the 3D virtual sub-object approaching or moving away from the human eye.

[0160] If the user feels that the current display parameters do not provide sufficient stimulation to the human eye when each 3D virtual sub-object is dynamically displayed with various depths of field in the 3D space corresponding to the 3D virtual screen, the user can input adjustment parameters by himself, such as inputting the target flow speed and target volume size corresponding to each 3D virtual sub-object.

[0161] After receiving the adjustment parameters, the display parameters of each 3D virtual sub-object can be adjusted according to the adjustment parameters to obtain updated display parameters. For example, the flow speed in the display parameters of each 3D virtual sub-object is adjusted to the target flow speed in the adjustment parameters to obtain updated display parameters.

[0162] Finally, each 3D virtual sub-object is controlled to be dynamically displayed in a 3D space corresponding to the 3D virtual screen at a variety of depths of field according to the updated display parameters, so as to achieve a floating display effect of the 3D virtual sub-object approaching or moving away from the human eye.

[0163] The advantage of doing this is that the display parameters of each 3D virtual sub-object can be adjusted according to the user's own visual stimulation level, thereby increasing the stimulation level of each 3D virtual sub-object to the human eye when it is displayed floatingly, so that the human eye can pay attention to the depth of field changes of multiple 3D virtual sub-objects. In this way, when the human eye views the 3D virtual sub-objects, the viewing distance will change, thereby alleviating the eye fatigue caused by a fixed viewing distance.

[0164] As can be seen from the above content, in the embodiment of the present application, by displaying a three-dimensional virtual picture in a naked-eye three-dimensional display screen, a plurality of three-dimensional virtual sub-objects are displayed on the three-dimensional virtual picture, and the volume of each three-dimensional virtual sub-object is less than a preset volume threshold; determining the display parameters corresponding to each three-dimensional virtual sub-object when displayed in the naked-eye three-dimensional display screen; controlling each three-dimensional virtual sub-object to be dynamically displayed in a three-dimensional space corresponding to the three-dimensional virtual picture according to the display parameters, so as to achieve a floating display effect of the three-dimensional virtual sub-object approaching or moving away from the human eye. In this way, by displaying a three-dimensional virtual picture on a naked-eye three-dimensional display screen, a plurality of three-dimensional virtual sub-objects are included in the three-dimensional virtual picture, and the plurality of three-dimensional virtual sub-objects can be dynamically displayed at different depths of field according to the display parameters, thereby achieving a floating display effect of the three-dimensional virtual sub-object approaching or moving away from the human eye, so that when the human eye views the three-dimensional virtual sub-object, the viewing distance will change, thereby achieving the relief of eye fatigue caused by a fixed viewing distance. Furthermore, since the volume of each three-dimensional virtual sub-object is smaller than the preset volume threshold, each three-dimensional virtual sub-object will not cause strong stimulation to the human eye when it is dynamically displayed with different depths of field, thereby enabling the human eye lens to adjust within a comfortable adjustment range and relieving visual fatigue.

[0165] See also Figure 8 , Figure 8 2 is another flow chart of the method for alleviating visual fatigue provided by an embodiment of the present application. The method for alleviating visual fatigue may include the following steps:

[0166] Step 301: displaying a 3D virtual screen on a naked-eye 3D display screen, wherein a plurality of 3D virtual sub-objects are displayed on the 3D virtual screen, and the volume of each 3D virtual sub-object is smaller than a preset volume threshold;

[0167] Step 302: determining the viewing distance between the human eye and the naked eye 3D display screen;

[0168] Step 303: When the viewing distance is within a preset viewing distance range, multiply the viewing distance by a preset proportional coefficient to obtain a preset screen-out distance threshold;

[0169] Step 304: determining a target visual off-screen distance according to a preset off-screen distance threshold, and generating display parameters corresponding to each 3D virtual sub-object when displayed on the naked-eye 3D display screen according to the target visual off-screen distance, wherein the target visual off-screen distance is a minimum visual off-screen distance of each 3D virtual sub-object;

[0170] Step 305: determine the total display area of ​​the naked-eye 3D display screen, and determine the cross-sectional area of ​​each 3D virtual sub-object parallel to the naked-eye 3D display screen;

[0171] Step 306: Determine the cross-sectional area as the display area of ​​each 3D virtual sub-object, and generate display parameters corresponding to each 3D virtual sub-object when displayed on the naked-eye 3D display screen according to the display area, wherein the display area is within one thousandth of the total display area;

[0172] Step 307: determine a first speed of each 3D virtual sub-object in a depth direction perpendicular to the naked eye 3D display screen in the 3D space;

[0173] Step 308: determining the flow speed corresponding to each 3D virtual sub-object in the 3D space according to the first speed, and generating display parameters corresponding to each 3D virtual sub-object when displayed on the naked eye 3D display screen according to the flow speed;

[0174] Step 309: Control each 3D virtual sub-object to be dynamically displayed in a 3D space corresponding to the 3D virtual screen at a plurality of different depths of field according to the display parameters, so as to achieve a floating display effect of the 3D virtual sub-object approaching or moving away from the human eye.

[0178] like Fig. 9 As shown, the visual fatigue relief device 400 may include:

[0179] The display module 410 is used to display a 3D virtual picture in the naked eye 3D display screen, where a plurality of 3D virtual sub-objects are displayed on the 3D virtual picture, and the volume of each 3D virtual sub-object is less than a preset volume threshold;

[0183] Determine the viewing distance between the human eye and the naked eye 3D display screen;

[0184] When the viewing distance is within the preset viewing distance range, the viewing distance is multiplied by a preset proportional coefficient to obtain a preset screen-out distance threshold;

[0185] The target visual off-screen distance is determined according to a preset off-screen distance threshold, and the corresponding display parameters of each three-dimensional virtual sub-object when displayed on a naked-eye three-dimensional display screen are generated according to the target visual off-screen distance. The target visual off-screen distance is the minimum visual off-screen distance of each three-dimensional virtual sub-object.

[0186] In some implementations, the display parameters include at least a display area corresponding to each 3D virtual sub-object when displayed on a naked-eye 3D display screen. The determination module 420 is used to:

[0214] The RF circuit 501 can be used for receiving and sending signals during information transmission or calls. In particular, after receiving the downlink information of the base station, it is handed over to one or more processors 508 for processing; in addition, the data related to the uplink is sent to the base station. Usually, the RF circuit 501 includes but is not limited to an antenna, at least one amplifier, a tuner, one or more oscillators, a Subscriber Identity Module (SIM) card, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the RF circuit 501 can also communicate with the network and other devices through wireless communication. Wireless communication can use any communication standard or protocol, including but not limited to Global System of Mobile Communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), etc.

[0215] The memory 502 can be used to store software programs and modules. The processor 508 executes various functional applications and information retrieval by running the software programs and modules stored in the memory 502. The memory 502 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area may store data created according to the use of the terminal (such as audio data, a phone book, etc.), etc. In addition, the memory 502 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices. Accordingly, the memory 502 may also include a memory controller to provide the processor 508 and the input unit 503 with access to the memory 502.

[0216] The input unit 503 can be used to receive input digital or character information, and generate keyboard, mouse, joystick, optical or trackball signal input related to object setting and function control. Specifically, in a specific embodiment, the input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display screen or a touch pad, can collect touch operations of an object on or near it (such as operations of an object using a finger, a stylus or any other suitable object or accessory on or near the touch-sensitive surface), and drive the corresponding connection device according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. Among them, the touch detection device detects the touch orientation of the object, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 508, and can receive and execute commands sent by the processor 508. In addition, the touch-sensitive surface can be implemented using multiple types such as resistive, capacitive, infrared and surface acoustic wave. In addition to the touch-sensitive surface, the input unit 503 may also include other input devices. Specifically, other input devices may include, but are not limited to, one or more of a physical keyboard, function keys (such as a volume control key, a switch key, etc.), a trackball, a mouse, a joystick, and the like.

The display unit 504 may include a display panel. Optionally, the display panel may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. Further, the touch-sensitive surface may cover the display panel. When the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor 508 to determine the type of touch event. The processor 508 then provides a corresponding visual output on the display panel according to the type of touch event. Although in Fig.10 In the embodiment, the touch-sensitive surface and the display panel are used as two independent components to realize input and output functions, but in some embodiments, the touch-sensitive surface and the display panel can be integrated to realize input and output functions.

The audio circuit 506 may also include an earplug jack to provide communication between an external headset and the terminal.

[0220] WiFi is a short-range wireless transmission technology. The terminal can help the object to send and receive emails, browse web pages and access streaming media through the WiFi module 507. It provides wireless broadband Internet access for the object. Fig.10 A WiFi module 507 is shown, but it is understandable that it is not an essential component of the terminal and can be omitted as required without changing the essence of the invention.

[0221] The processor 508 is the control center of the terminal, and uses various interfaces and lines to connect various parts of the entire mobile phone. By running or executing software programs and / or modules stored in the memory 502, and calling data stored in the memory 502, the processor 508 performs various functions of the terminal and processes data, thereby monitoring the mobile phone as a whole. Optionally, the processor 508 may include one or more processing cores; preferably, the processor 508 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, object interface and application programs, etc., and the modem processor mainly processes wireless communications.
