Description

Technical Field

[0001] This application relates to the field of display control technology, and in particular to a display method, apparatus, electronic device, and readable storage medium. Background Technology

[0002] With the increase in the time spent using electronic devices (such as smartphones, laptops, and tablets), the prevalence of myopia has risen significantly. This is largely attributed to close-range work activities under academic pressure, such as reading at a distance of less than 30 centimeters for more than 30 minutes.

[0003] Current myopia prevention programs primarily rely on hardware devices, such as head-worn defocus glasses or contact lenses. These programs aim to slow myopia progression by inducing positive defocus in the area outside the fixation point through physical lens design. These programs reduce stimulation of axial elongation of the eyeball by generating controlled blur signals in the peripheral vision of the central field of vision while maintaining clarity in the central field. Clinical studies have shown that this is effective in inhibiting myopia progression, but requires prolonged wear.

[0004] However, the aforementioned myopia prevention solutions rely on hardware devices such as defocus glasses or contact lenses, which users must wear to achieve the preventive effect. This can cause eye strain in some children, and compliance needs to be improved. For users who rely on digital devices, especially children, these solutions are inconvenient to use. Summary of the Invention

[0026] The content to be displayed is Gaussian blurred to obtain the processed content to be displayed.

[0027] Display the processed content to be displayed.

[0028] In one embodiment, controlling the display screen to blur the content to be displayed includes:

[0029] Set a full-screen blur layer in the user interface layer of the display screen. The size of the full-screen blur layer is the same as the size of the entire display screen, and the entire full-screen blur layer is blurred.

[0030] Cover the content to be displayed with a full-screen blurred layer.

[0031] Thirdly, this application also provides a display device, comprising:

[0032] The acquisition module is used to acquire the content to be displayed on the screen.

[0033] A gaze point acquisition module is used to acquire the user's gaze point on the display screen in real time;

[0034] A region determination module is used to determine a first region on the display screen based on the gaze point, wherein the first region includes the gaze point, and the first region is updated as the gaze point is updated.

[0035] The control module is used to control the first area on the display screen to blur the content to be displayed at a first time interval, wherein the duration of the control of the first area to blur the content to be displayed is a second time interval.

The display method provided in this embodiment, by controlling the intermittent blurring of the area where the gaze point is located on the display screen, eliminates the need for users to wear defocus glasses, improving the convenience of myopia prevention for users.

[0053] The display method provided in this application embodiment can be applied to, for example, Figure 1 In the application scenarios shown. For example... Figure 1 As shown, a user is using electronic device 100 to view content on the display screen 110 of electronic device 100. Figure 1 As shown, the electronic device 100 is equipped with a front-facing camera 120. Exemplarily, the front-facing camera 120 is independent of the display screen 110, or exemplaryly, the front-facing camera 120 is integrated into the display screen 110. Figure 2 In this context, electronic device 100 can be a tablet computer. Figure 1 It illustrates how electronic devices capture the user's gaze point in real time using a front-facing camera and apply intermittent blurring to the central area to simulate a discontinuity in accommodation.

[0054] In other embodiments, the electronic device may be, but is not limited to, various personal computers, laptops, smartphones, and head-mounted devices with displays. Head-mounted devices may be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc.

[0056] Those skilled in the art will understand that Figure 2 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the electronic device to which the present application is applied. The specific electronic device may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0057] In the field of digital displays, myopia prevention methods often focus on peripheral blur adjustment to simulate a positive defocus effect. For example, some display systems use eye tracking to create a blur distribution on the periphery of the screen while maintaining central sharpness, providing a lens-like defocus signal. However, these methods do not address intermittent central blur at the fixation point; they merely achieve continuous peripheral blur adjustment or overall screen blur, failing to optimize the blur effect and not fully utilizing real-time fixation dynamics for precise intermittent intervention.

[0058] While wearing defocus glasses or contact lenses can be effective in inhibiting myopia progression to some extent, they rely on hardware devices or fixed peripheral blur patterns, requiring users to wear glasses to achieve the preventive effect. This can easily cause eye strain in some children, leading to low compliance. For users who heavily rely on digital devices, especially children, the aforementioned digital methods lack an intermittent central blur mechanism targeting the fixation point, making it difficult to flexibly adapt to user behavior to optimize the preventive effect.

[0059] In one exemplary embodiment, please refer to Figure 3 This paper provides a display method and describes the steps involved in obtaining intermittent central blur from a fixation point. This embodiment applies this method to... Figure 1 Using the electronic device shown as an example, this method simulates a defocus effect by dynamically controlling the blurring of the display screen content, achieving intermittent central blurring at the user's gaze point, thereby slowing down the progression of myopia.

[0060] like Figure 3 As shown, the method includes steps 302 to 308, wherein:

[0061] Step 302: Obtain the content to be displayed on the screen.

[0062] The content to be displayed refers to the content that needs to be displayed on the screen; the content to be displayed on the screen is updated in real time.

[0063] For example, the content to be displayed can refer to the content displayed in the next frame according to the screen refresh rate. For instance, when the screen refresh rate is 60Hz, the content to be displayed is updated 60 times per second.

[0064] For another example, the update frequency of the content to be displayed can be determined according to the update frequency of the user's gaze point. For instance, the user's gaze point trajectory on the display screen can be obtained, the update frequency of the gaze point can be determined, and the content to be displayed on the display screen can be updated each time the gaze point is updated, so that the content to be displayed on the display screen can be customized according to the movement of the gaze point.

[0065] Step 304: Acquire the user's gaze point on the display screen in real time.

[0066] In one possible implementation, the gaze point is obtained based on a preset gaze point prediction model. The process of obtaining the gaze point in this implementation includes: acquiring the user's eye video data in real time, and obtaining the user's gaze point on the display screen based on the eye video data and the preset gaze point prediction model.

[0067] For example, a user's eye video data can be acquired through the front-facing camera of an electronic device. The user's eye video data is input into a preset gaze prediction model to obtain the user's gaze point on the display screen. This gaze point is a sequence of gaze point data output by the gaze prediction model after analyzing the user's eye video data. The gaze point sequence data includes the position data of the gaze point on the display screen and the corresponding timestamp. The latest position data and its corresponding timestamp in the gaze point sequence data are determined as the current user's gaze point on the display screen, and a first region is determined based on this gaze point.

[0068] In one possible implementation, the foveation prediction model can be implemented using a lightweight AI (Artificial Intelligence) model, for example, based on an open-source foveation estimation model, or based on a neural network model for sequential data.

[0069] For example, the gaze prediction model can be implemented using one or more of the following: convolutional neural networks, recurrent neural networks, long short-term memory networks, and Transformer models.

[0070] For example, a model deployment and operation framework can be used to deploy a trained gaze prediction model locally on an electronic device, enabling localized processing of eye-tracking data such as gaze points, ensuring user privacy and security, and enhancing user trust.

[0071] In one possible implementation, the fixation prediction model can monitor the number of blinks at a frequency of 1 Hz and achieve a fixation distance estimation with a resolution of ±2 cm within a distance range of 20 cm to 50 cm, with a fixation angle accuracy of ±1 degree.

[0072] Step 306: Determine a first region on the display screen based on the gaze point, wherein the first region includes the gaze point. The first region updates in real time following updates to the gaze point.

[0073] For example, please refer to Figure 1 The first region 112 is a continuous area on the display screen that surrounds and includes the gaze point 111. Figure 1 In the image, the blue line represents the user's gaze line. Figure 2 The part inside the dashed circle represents the first region 112.

[0074] Step 304: At each first time interval, control the first area on the display screen to blur the content to be displayed, wherein the duration of controlling the blurring of the first area is the second time interval.

[0075] Myopia is associated with abnormal growth of the axial length of the eye, and the choroid, a vascularized tissue located behind the retina, is considered a key physiological mechanism for regulating axial growth and responding to optical defocus signals. Choroidal thickening is often associated with inhibiting axial growth (anti-myopia). Studies have found that the eye's growth regulation mechanism can sense and respond to optical defocus signals on the retina and adjust by changing choroidal thickness; frequent focal shifts in visual stimuli can disrupt the stability of retinal signals, leading to increased choroidal thickness. For example, children maintaining a certain amount of outdoor activity can reduce the development of myopia or prevent its onset, possibly related to frequent changes in fixation distance, leading to changes in the focal point, which helps inhibit axial growth.

[0076] In this embodiment, the area where the user's gaze point is located on the display screen is blurred at regular intervals. This interrupts the user's gaze focus every so often, disrupting the user's visual stability signal and slowing down the onset of myopia.

[0077] The duration for which the first region remains blurred is defined as a second duration, which allows the human eye to perceive the region where the fixation point is located changing from clear to blurred. In one possible implementation, the second duration is determined based on the human eye's tolerance delay for blurring. For example, the second duration is greater than the human eye's tolerance delay for blurring, thus causing the human eye to notice the blurring of the fixation point and a change in focus. For example, the second duration is greater than 50 ms; optionally, the second duration can range from 100 ms to 500 ms.

[0078] The first duration refers to the length of time the first area remains clearly displayed. If the area where the gaze point is located is blurred too frequently, it will lead to a poor user experience, so the first duration should not be too short.

[0079] In one possible implementation, the first duration is a fixed duration; for example, the first duration is equal to 1 minute.

[0080] In one possible implementation, the initial duration can be dynamically adjusted based on the user's screen usage time. For example, if the user's screen usage time is short, the initial duration can be relatively long, such as a base duration of 2 minutes. As the user's screen usage time increases, the initial duration gradually decreases; for example, if the user's screen usage time exceeds 10 minutes, the initial duration decreases to 1 minute and 30 seconds; if the user's screen usage time exceeds 20 minutes, the initial duration decreases to 1 minute. Simultaneously, a minimum initial duration is set to prevent a poor user experience due to an excessively short initial duration.

[0081] In one possible implementation, the first duration can be determined based on the display type of the content to be displayed. For example, the first duration for document-type content can be greater than the first duration for video-type content.

[0082] In one possible implementation, the process of controlling the first area on the display screen to blur the content to be displayed includes: performing Gaussian blur processing on the portion of the content to be displayed corresponding to the first area to obtain the processed content to be displayed, wherein the portion of the processed content to be displayed corresponding to the first area is blurred. Optionally, the entire content to be displayed is subjected to Gaussian blur processing to obtain the processed content to be displayed, wherein the processed content to be displayed includes the entire portion corresponding to the first area, which is blurred.

[0083] In one possible implementation, the process of controlling the first area on the display screen to blur the content to be displayed includes: setting a first blur layer on the UI (User Interface) layer of the display screen, wherein the size of the first blur layer is the same as the size of the entire display screen, and the position corresponding to the first area in the first blur layer is blurred; covering the display screen with the first blur layer so that the first area blurs the content to be displayed. The first blur layer is calculated and updated in real time based on changes in the gaze point.

[0084] In the embodiments of this application, the intensity parameter σ in the Gaussian blur processing can be determined based on the principle of regular astigmatism defocus visual optics; for example, the value range of σ is 2px (pixels) to 3px, corresponding to a cylindrical power of +1.0D to +2.0D, where D represents diopter.

[0085] The display method provided in the above embodiments acquires the content to be displayed on the display screen, obtains the user's gaze point on the display screen in real time, and determines a first area on the display screen based on the gaze point. The first area includes the gaze point and updates in real time following the gaze point. Every first time interval, the content to be displayed in the first area on the display screen is blurred, and the duration of this blurred display is a second time interval. Thus, when a user uses an electronic device and gazes at the display screen, every first time interval, the content to be displayed in the area where the user's gaze point is located is intermittently blurred, thereby interrupting the user's focus of vision at regular intervals, disrupting the user's visual stability signal, and slowing the onset of myopia. This method differs from related myopia prevention display methods that use multi-focal peripheral blurring or overall screen adjustment to simulate positive defocus. Instead, it innovatively achieves intermittent central blurring at the gaze point, avoiding the inconvenience caused by requiring users to wear defocus glasses to achieve myopia prevention effects, as in related technical solutions. The display method provided in this embodiment, by controlling the intermittent blurring of the area where the gaze point is located on the display screen, eliminates the need for users to wear defocus glasses, improving the convenience of myopia prevention for users.

[0086] The display method provided in this application can be used across operating systems and device types, with a flexible application environment and compatibility with multiple application platforms. For example, it can run on operating systems such as iOS, Android, and HarmonyOS, and is suitable for various devices such as smartphones, laptops, and tablets. For example, cross-platform compatibility is achieved using standard APIs (such as Core ML for iOS and TensorFlow Lite for Android).

[0087] In one possible implementation, the display method can be integrated into application software, such as document reading, video, social networking, or learning applications. In another possible implementation, the display method can be located at the system level of the electronic device.

[0088] In one exemplary embodiment, please refer to Figure 4 ,based on Figure 3 The illustrated embodiment further explains the process of region updating and perimeter blur preservation. For example... Figure 4 As shown, the provided display method further includes steps 402 and 404. Wherein:

[0089] Step 402: Determine the second region based on the fixation point or the first region.

[0090] The distance between the second region and the gaze point is greater than the distance between the first region and the gaze point. It is understood that the second region includes all areas on the display screen other than the first region. For example, the first region is a circular area with the gaze point as its center and a preset distance as its radius, and the second region is all areas on the display screen other than the first region.

[0091] In this embodiment, the first and second regions update in real time following the gaze point. The gaze point changes in real time, and the corresponding first and second regions also change accordingly. The update speed of the gaze point can be determined based on the camera's frame rate, the inference speed of the gaze point prediction model, and the processing resources of the electronic device.

[0092] In one possible implementation, the process of determining a first region on the display screen based on the gaze point includes: obtaining the eye-screen distance between the user's eyes and the display screen; and obtaining the first region based on the gaze point, the eye-screen distance, and a preset gaze clarity angle.

[0093] For example, eye video data acquired through the front-facing camera of an electronic device is analyzed to obtain positional data such as the user's pupil position, corner of the eye, and bridge of the nose. Combined with the actual distance between key facial points (e.g., interpupillary distance is approximately 63mm) as a reference size, the eye-screen distance is obtained by converting the pixel distance in the image to the actual physical distance.

[0094] Another example is the use of an infrared sensor on an electronic device to measure the distance between the user's eyes or head and the display screen, thus obtaining the eye-to-screen distance.

[0095] In one possible implementation, the process of obtaining the first region based on the fixation point, eye-screen distance, and a preset fixation clarity angle includes: according to the formula The radius r of the region is calculated. mm Based on the area radius and the pixel density of the display screen, according to the formula... Converting the region radius to pixel units, we obtain a region radius of r centered on the fixation point. px The circular area of ​​the pixel is the first region. Here, D represents the eye-to-screen distance (in millimeters), θ represents the preset viewing angle, mm-per-pixel represents the length per pixel in millimeters, PPI represents pixels per inch, and 25.4 is a conversion constant between millimeters and inches (25.4mm = 1 inch). For example, the viewing angle ranges from 5° to 7°. In this embodiment, the size of the first region takes into account both the eye-to-screen distance and the pixel density of the display screen, allowing the size of the first region to adapt to different display screen sizes and optimize visual comfort.

[0096] In one possible implementation, the process of determining a first region on the display screen based on the gaze point includes: acquiring the size data of the display screen; obtaining the first region based on the size data, the gaze point, and a preset region coefficient. For example, the region coefficient ranges from 0.1 to 0.2; obtaining the region length based on the size data and the region coefficient; and obtaining a circular first region with the gaze point as the center and the region length as the radius, or a square first region with the gaze point as the center point and the region length as the side length. In this implementation, the first region is adaptively determined based on the display screen size data, allowing the size of the first region to adapt to display screens of different sizes, thus optimizing visual comfort.

[0097] For example, after determining the first region, the area on the display screen other than the first region is determined as the second region.

[0098] For example, after determining the first region, the region in the display interface corresponding to the current application other than the first region is determined as the second region.

[0099] Step 404: Control the second area to display the content to be displayed in a blurred state.

[0100] In one possible implementation, the process of controlling the second region to blur the content to be displayed includes: performing Gaussian blur processing on the part of the content to be displayed corresponding to the second region to obtain the processed content to be displayed, wherein, in this implementation, the part of the processed content to be displayed corresponding to the second region is blurred, and the part corresponding to the first region is clear.

[0101] In one possible implementation, the process of controlling the blurring of the content to be displayed in the second area includes: setting a second blur layer at the UI level of the display screen, wherein the size of the second blur layer is the same as the size of the entire display screen, the portion corresponding to the first area in the second blur layer is clear, and the portion corresponding to the second area is blurred; covering the display screen with the second blur layer so that the content to be displayed in the second area is blurred. The second blur layer is calculated and updated in real time based on changes in the gaze point.

[0102] In this embodiment, throughout the user's use of the display screen, the second area is controlled to be blurred. The first and second areas can also be referred to as the direct gaze area and the defocus blurred area, respectively. Specifically, the first area is blurred at intervals of a first duration and remains blurred for a second duration, while the first area remains clear for the remaining time. Thus, the blurred display outside the user's direct gaze area not only intermittently disrupts the user's visual stability signal but also achieves the defocus effect of clear focus at the gaze point and blurred periphery in defocus glasses. This integrates the myopia prevention mechanism of defocus glasses into the display method of electronic devices, improving the myopia prevention effect.

[0103] In one possible implementation of this embodiment, the process of controlling the first area on the display screen to blur the content to be displayed at each first time interval includes: repeatedly executing: after controlling the first area to clearly display the content to be displayed and the second area to blur the content to be displayed for a first time interval, controlling the display screen not to refresh the content to be displayed for a second time interval.

[0104] In this embodiment, the content to be displayed on the screen is based on the first area remaining clear and the second area being blurred. The content to be displayed is not refreshed for a second time interval after a first time interval, allowing the screen to update the content in real time as the user's gaze moves. After the first time interval, the screen refreshes the content with a second time interval lag, but the user's gaze continues to move. The user sees the blurred area from the previous content, causing a change in the user's focus. In one possible scenario, the user's gaze stops moving for a second time interval, and only resumes moving after the screen continues refreshing the content.

[0105] Figure 5 This is a schematic diagram illustrating the effect of controlling the blurring of the content to be displayed in a first area of ​​the display screen at first intervals in one embodiment. It demonstrates the intermittent blurring effect in the gaze point area and its disruption to visual stability signals. For example, as shown... Figure 5 As shown, Figure 5 (a)-(e) in the diagrams correspond to the real-time refresh of the content to be displayed on the screen as the gaze point moves, up to... Figure 5 At the moment indicated by (e), the display screen has continuously displayed the content to be displayed in the first area clearly and in the second area blurred for the first duration. Figure 5 (f) in the diagram corresponds to the display screen not refreshing the content to be displayed, where the gaze point 111 is updated relative to the previous gaze point update time (i.e. Figure 5 At time (e) in the diagram, the position has been moved to the next location, and the first and second regions have been updated along with the fixation point 111. However, the display screen has not refreshed the content to be displayed at this time. Instead, the display screen shows the content to be displayed at the previous fixation point update time. Figure 5 The content to be displayed corresponding to (e) causes the user's gaze to fall on the blurred area, thus changing the user's focus; while maintaining Figure 5 As shown in (f), after the second duration, the display screen continues to refresh the content to be displayed, as... Figure 5 As shown in (g)-(i), the content to be displayed at this time is based on the first region 112 remaining clear and the second region being blurred. The first region 112 where the gaze point 111 is located is clear, and the second region outside the first region 112 is blurred. This continues for another first duration, and then the display screen is controlled not to refresh the content to be displayed for a second duration. Figure 5 In the schematic diagrams shown in (a)-(i), the area outside the first region 112 is the second region, and the blue lines with arrows represent the predicted movement trajectory of the user's gaze point 111 on the display screen.

[0106] In this implementation, by delaying the refresh of the content to be displayed, the area where the user's gaze point is located is blurred at regular intervals, which breaks the stability of the user's visual signal and inhibits the development of myopia.

[0107] In one exemplary embodiment, a display method is provided, in which the method is applied to Figure 1 The following is an explanation using the electronic device shown as an example, including steps S1 and S5, wherein:

[0108] Step S1: Acquire the user's eye video data in real time.

[0109] Step S2: Based on eye video data and a preset gaze prediction model, obtain the user's gaze point on the display screen.

[0110] Step S3: Obtain the eye-screen distance between the user's eyes and the display screen.

[0111] Step S4: Based on the fixation point, eye-screen distance, and preset fixation clarity angle, a first region and a second region are obtained. The first region includes the fixation point, and the second region is the region on the display screen other than the first region. The first region and the second region are updated in real time with the fixation point.

[0112] Step S5: After controlling the first area to be clearly displayed and the second area to be blurred for a first duration, control the display screen not to refresh the content to be displayed for a second duration.

[0113] This application embodiment utilizes a fixation point prediction model to track and predict user gaze. Combined with intermittent blurring of the fixation point area, it simulates a therapeutic myopia defocus effect on a digital screen, providing a digital solution for myopia prevention. Based on the fixation point prediction model and acquired user eye video data, it tracks the user's fixation point, dynamically updates a first region and a second region, and controls the blurring of the second region to achieve a induced, regular astigmatic defocus effect. After a first time interval, it delays brushing the content to be displayed, achieving intermittent blurring of the first region. This interrupts the user's focus, disrupts the user's visual stability signal, and slows the onset of myopia.

[0114] In one exemplary embodiment, please refer to Figure 6 This provides a display method that is applied to Figure 1 The following explanation uses the electronic device shown as an example, including steps 602 and 604, wherein:

[0115] Step 602: Obtain the content to be displayed on the screen.

[0116] Step 604: Control the display screen to blur the content to be displayed every first time interval, wherein the duration of the blurred display is the second time interval.

[0117] In one possible implementation, controlling the display screen to blur the content to be displayed includes: performing Gaussian blur processing on the entire content to be displayed to obtain the processed content to be displayed, and displaying the processed content to be displayed, wherein the entire area of ​​the processed content to be displayed is blurred.

[0118] In one possible implementation, controlling the display screen to blur the content to be displayed includes: setting a full-screen blur layer in the user interface layer of the display screen, wherein the size of the full-screen blur layer is the same as the size of the entire display screen, the entire full-screen blur layer is blurred, and covering the content to be displayed with the full-screen blur layer, so that the entire display screen is blurred.

[0119] In this embodiment, the content to be displayed on the screen is blurred at first intervals, including the area where the user's gaze point is located, thus disrupting the stability of the user's visual signal and inhibiting the progression of myopia. Simultaneously, the display method provided in this embodiment does not require real-time acquisition of the gaze point and the first area, reducing the computational resource consumption of the electronic device and improving the efficiency of display control.
