[0002] With the continuous development of Internet technology, users are no longer limited to traditional ways such as television to watch video media, but can watch network video media through the network. The bullet screen is an interactive comment that is rapidly displayed in the form of text when watching network video media. Users can not only express their own opinions by publishing bullet screens, but also interact with the displayed bullet screens, thereby increasing the interest of users in watching video media.

[0003] The methods described in this section can not be the methods previously conceived or used. Unless otherwise indicated, nothing in this section should be assumed to be prior art merely because it is included in this section.

[0020] Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, which include various details of the embodiments of the present disclosure to assist in understanding them. These should be considered in their context only as illustrative. Thus, those of ordinary skill in the art will recognize various changes and modifications of the embodiments described herein, without departing from the scope of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0021] In the present disclosure, the terms "first", "second", and the like are used to describe various elements only and do not intend to limit the positional relationship, the chronological relationship, or the importance of the elements, and such terms are only used to distinguish one element from another. In some examples, the first element and the second element can refer to the same instance of the element, and in some cases, based on the context of the description, they can also refer to different instances.

[0022] The terms used in the description of various described examples in the present disclosure are only for the purpose of describing specific examples and are not intended to be limiting. Unless the number of elements is specifically limited, the element can be one or more than one, unless the context clearly indicates otherwise. In addition, the term "and / or" used in the present disclosure encompasses any one of the listed items and all possible combinations thereof.

[0023] With the continuous development of Internet technology, users are no longer limited to traditional ways such as television to watch video media, but can watch network video media through the network. The barrage is an interactive comment that is rapidly displayed in the form of text when watching network video media. Users can not only express their own opinions by publishing barrages, but also interact with the displayed barrages, thereby increasing the interest of users in watching video media.

[0024] The current display mode of the barrage usually includes barrage arrangement, style adjustment, animation effect, occlusion processing, adaptive display, etc. The barrage arrangement refers to displaying the barrage according to the time when the user sends the barrage and a certain display rule, for example, scrolling the barrage from the right side to the left side of the display screen of the terminal device, displaying the barrage at a fixed position, or displaying the barrage in different regions, etc. The style adjustment refers to displaying the barrage in a certain font, color, etc. The animation effect refers to giving a specific barrage a specific animation effect, for example, according to the meaning of the text represented by the barrage. The occlusion processing refers to dynamically adjusting the position and transparency of the barrage by calculating the position and size of the barrage to avoid the barrage from occluding important content in the played video. The adaptive display refers to adjusting the size and layout of the barrage according to the current display screen size and resolution of the terminal device, so that the barrage can be properly displayed on various devices.

[0025] However, the inventors found that for some hot videos, there may be a situation that a large number of users send barrages at the same time, which will cause a large number of barrages to appear on the screen at the same time. Even if the barrage display mode as described above is adopted, the situation that the barrages overlap with each other and the specific text content of the barrage cannot be clearly recognized may still occur. This will greatly affect the reading and viewing experience of the user, and some important information or comments will be ignored.

[0026] Therefore, the embodiments of the present disclosure provide a barrage display method, which can obtain eye tracking information of a client user who is watching a played video in real time, and adjust display attribute information of one or more barrages associated with the eye tracking information. Since the eye tracking information can reflect the gaze point position of the client user on the current display interface in real time, it can better reflect the real attention and interest of the client user to the barrage on the display interface. Based on this, the display attribute information of the associated barrage is automatically adjusted, which can highlight the display of the barrage that the client user is interested in, so that the user can watch clear and complete barrage content, which not only improves the user's viewing experience, but also facilitates the realization of barrage display control for individual differences between different users.

[0027] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0039] Figure 1 The system 100 can be configured and operated in various ways to enable the application of various methods and apparatuses described in accordance with the present disclosure.

[0040] Figure 2 A flowchart of a method 200 of displaying a barrage in accordance with an embodiment of the present disclosure is shown. As shown, the method 200 can include: step S210, obtaining eye tracking information of a client user watching a played video; step S220, determining one or more target barrages associated with the eye tracking information from a plurality of barrages presented in the played video based on the eye tracking information; and step S230, adjusting display attribute information of the one or more target barrages. Figure 2

[0041] By obtaining the eye tracking information of the client user watching the played video in real time, the real attention and interest of the client user to the barrages on the display interface can be reflected. On this basis, adjusting the display attribute information of the associated one or more barrages can highlight the barrages that the client user is interested in, so that the user can watch clear and complete barrage content, not only improving the user's watching experience, but also facilitating the realization of barrage display control for individual differences between different users.

[0042] It will be understood that the eye tracking information of the client user watching the played video can be obtained in real time, and based thereon to determine the target barrages and adjust the display attributes of the target barrages, or information about the target barrages can be stored, and the display attribute adjustment can be performed when the user watches the video again, alone or together with the target barrages determined in real time.

[0043] According to some embodiments of the present disclosure, in step S210, the eye tracking information can be obtained by real-time tracking and recording the movement trajectory and fixation point of the eyes of the client user through eye movement tracking technologies such as infrared light, high-speed camera, etc. For example, an infrared light source and a camera can be used to capture the infrared light reflected by the eyes of the client user, and the fixation point and movement path of the eyes can be determined by analyzing the reflection pattern and eye shape. Further, a high-speed camera can record the micro-movement and transition of the eyes at a speed of, for example, 100 frames per second. Through a corresponding calibration process, an accurate mapping relationship can be established, thereby ensuring the accuracy and accuracy of the eye tracking information.

[0044] ​According to some embodiments of the present disclosure, in step S220, the eye tracking information can include current eye focus position information of the client user. The current eye focus position information may, for example, be position coordinates of the current eye focus. For example, when viewing the terminal device in landscape mode, a coordinate system can be established with the horizontal direction as the X axis, the vertical direction as the Y axis, and the direction perpendicular to the display screen of the terminal device as the Z axis. In this case, the current eye focus position information may, for example, be (Xi, Yi, Zi).

[0045] Figure 3 A flowchart of determining target bullet screens associated with a current time according to eye tracking information is shown according to an embodiment of the present disclosure. As shown in Figure 3 determining one or more target bullet screens associated with the eye tracking information from a plurality of bullet screens presented in a played video based on the eye tracking information can include: step S322, determining a subset of bullet screens within a first threshold distance range from the current eye focus position information included in the eye tracking information from the plurality of bullet screens; and step S324, determining one or more target bullet screens based on the subset of bullet screens.

[0046] According to some embodiments of the present disclosure, after obtaining the eye tracking information and the eye focus position coordinates indicated thereby, a bullet screen search frame can be determined with the coordinates as the center and a specific threshold distance as the radius. Then, all bullet screens on the current display interface falling within the bullet screen search frame can be selected as the subset of bullet screens.

[0047] It should be noted that falling within the bullet screen search frame can mean that the bullet screen completely falls within the bullet screen search frame, or that the bullet screen partially falls within the bullet screen search frame (for example, just rolling into the bullet screen search frame or about to roll out of the bullet screen search frame).

[0048] It should also be noted that the threshold distance can be any suitable value, such as 30 pixels, 50 pixels, 75 pixels, etc. The threshold distance can also be adapted according to actual application scenarios or needs, etc. For example, in the case of a large number of bullet screens, the threshold distance can be adapted to be smaller than in the case of a small number of bullet screens. For another example, in the scenario of a game video, the threshold distance can be adapted to be smaller than in the scenario of viewing a normal video. Thus, the target bullet screens corresponding to the client user can be more accurately determined.

[0049] Compared with the traditional way that the user manually selects the barrage of interest, by determining the current eye focus position information and the corresponding threshold distance range, the barrage area that more reflects the user's focus and interest point can be automatically determined, so that more accurate target barrage can be obtained from all the currently presented barrages. On the other hand, by setting the threshold distance range, in the case that there is no barrage at the current eye focus position, the target barrage search area can be expanded to avoid missing.

[0050] According to some embodiments of the present disclosure, the step S324 of determining one or more target barrages based on the barrage subset can include determining each barrage in the barrage subset as a target barrage.

[0051] According to some other embodiments of the present disclosure, with reference to Figure 4 , the step S324 of determining one or more target barrages based on the barrage subset can include the step S326 of calculating the distance between each barrage in the barrage subset and the current eye focus position indicated by the current eye focus position information, and the step S328 of determining the barrage as a target barrage in response to determining that the distance is less than the second threshold distance.

[0052] As described above, falling into the barrage search box can refer to the part of the barrage falling into the barrage search box (for example, just rolling into the barrage search box, about to roll out of the barrage search box). However, in general, the barrage about to roll out of the barrage search box can not be the barrage that the user expects to focus on and understand, and the barrage just rolling into the barrage search box can not have attracted the user's attention, so in some cases, such as the two types of barrages described above, the barrage can not accurately reflect the user's real attention and interest. By further calculating the distance between each barrage falling into the barrage search box and the current eye focus position, barrages that do not meet the needs of the scene can be further filtered out, thereby avoiding frequent automatic adjustment of the barrage display attribute operation.

[0053] According to some embodiments of the present disclosure, in the step S326, the distance between each barrage and the current eye focus position can be calculated by the following formula:

[0054]

[0055] wherein d represents the distance between the barrage m and the current eye focus i, (Xi, Yi, Zi) represents the coordinate value of the current eye focus i, and (Xm, Ym, Zm) represents the coordinate value of the center point of the barrage frame where the barrage m is located. In this document, the barrage frame can refer to a rectangular frame including the barrage, and the center point is the center point of the rectangular frame.

[0056] Further, in step S328, the second threshold distance can be set to any suitable value less than or equal to the threshold distance range, and the barrage whose distance value calculated according to the above formula is greater than the second threshold distance is filtered out, so as to obtain more accurate target barrage.

[0057] According to some embodiments of the present disclosure, the barrage display method 200 can further include updating the one or more target barrages, wherein updating the one or more target barrages can include: sorting the distance between each target barrage and the current eye focus position indicated by the current eye focus position information; and selecting the first preset number of target barrages with the smallest distance as the updated target barrage.

[0058] According to some examples, the first preset number can be any integer that meets the actual scene requirements, including but not limited to 5, 8, 10, etc., which may, for example, depend on the total number of all barrages currently displayed.

[0059] By sorting the distance between each target barrage and the current eye focus position, an ordered target barrage set arranged in ascending order can be obtained. By selecting the first preset number of barrages from the ordered target barrage set as the updated target barrage, the range of target barrage can be further narrowed, and the barrage that the user is really interested in or interested in can be more accurately determined.

[0060] Figure 4 A flowchart of a barrage display method 400 according to some other embodiments of the present disclosure is shown. Referring to Figure 4 , the method 400 can include steps S410-S430 similar to steps S210-S230 in the barrage display method 200 described with reference to Figure 2 ; and step S440, obtaining gaze duration information of the client user for the one or more target barrages.

[0061] If the current displayed number of bullet screens is large, there can be a case that the user only glances at all bullet screens without focusing on a certain bullet screen of interest. In this case, if the target bullet screen is determined according to all eye tracking information of the user in the glancing process, and the display attribute of the bullet screen is adjusted accordingly, a large number of bullet screens can be adjusted in display attribute, the display interface is cluttered, but the user's real intention is not to focus on these bullet screens. By obtaining the gaze duration information of the determined target bullet screen, the real intention of the user can be further determined. For example, if the gaze duration on a certain target bullet screen is only 0.1 second, it can be that the user only glances at the bullet screen. For another example, if the gaze duration on a certain target bullet screen is 1 second, it can mean that the user really focuses on the bullet screen, so it can be determined that the bullet screen is the user's focus point or point of interest. Adjusting the bullet screen on this basis not only meets the actual needs of the user and improves the viewing experience, but also avoids the inconvenience brought by the operation of adjusting the display attribute of a large number of bullet screens.

[0062] According to some embodiments of the present disclosure, the step S440 of obtaining the gaze duration information of the client user on the one or more target bullet screens can include: obtaining the current eye focus position, the corresponding time stamp and other eye movement features from the obtained eye tracking information; then, obtaining the trajectory change of the client user's focus point according to the current eye focus position, the corresponding time stamp and other eye movement features, and counting the gaze duration on each target bullet screen.

[0063] According to some embodiments of the present disclosure, the step S440 of obtaining the gaze duration information of the client user on the one or more target bullet screens can include: for each of the one or more target bullet screens: obtaining a time stamp list corresponding to the target bullet screen, wherein each time stamp in the time stamp list represents a time when the bullet screen was previously determined as a target bullet screen; and updating the time stamp list corresponding to the target bullet screen to include the current time.

[0064] Specifically, a corresponding timestamp list can be created for each target barrage, and whenever the barrage is determined to be a target barrage, the corresponding time is recorded in the timestamp list. For example, the eye tracking data can be called back at fixed time intervals (e.g., 0.5 seconds). In response to determining that the barrage is first determined to be a target barrage at the current time t, a timestamp list attention_time_list can be created for the barrage, and the time t is recorded in the list, attention_time_list = [t]. In response to determining that the barrage is determined to be a target barrage at a time before the current time t, for example, 1.5 seconds, 1 second, 0.5 seconds, then attention_time_list = [t-1.5, t-1, t-0.5, t]. It should be understood that non-fixed time intervals can also be used to call back the eye tracking data. Similarly, the time determined to be a target barrage is also recorded in the corresponding timestamp list.

[0065] By creating a timestamp list for each target barrage and recording the time when each barrage is determined to be a target barrage, the user's gaze duration on the barrage within a certain time period can be quickly calculated. Compared with obtaining the trajectory change of the user's focus point and directly timing the attention duration of each barrage, the above operation is simpler and requires less data storage.

[0066] According to some embodiments of the present disclosure, step S230 and / or step S430, adjusting the display attribute information of one or more target barrages can include: for each of the one or more target barrages, determining whether the corresponding gaze duration information of the target barrage meets a first preset standard; and in response to determining that the corresponding gaze duration information of the target barrage meets the first preset standard, adjusting the display attribute information of the target barrage.

[0067] By comparing the gaze duration with the first preset standard, it can be determined whether the user's gaze on the target barrage lasts for a preset time, thereby determining whether the user is truly interested in the target barrage. On this basis, the barrage is adjusted, which is more in line with the actual needs of the user, and avoids the operation of constantly adjusting the display attributes of a large number of barrages.

[0068] According to some examples, the first preset standard can be that the user's continuous gaze on the target barrage lasts for a preset time, for example, 2 seconds, 3 seconds.

[0069] According to some examples, the second preset number can be any integer satisfying actual scene requirements, including but not limited to 4, 6, 8, etc. Similarly, the third preset number can also be any integer satisfying actual scene requirements and less than the second preset number. The scope of protection required by the present disclosure is not limited in this respect.

[0070] According to some examples, the second preset number can be any integer satisfying actual scene requirements, including but not limited to 4, 6, 8, etc. Similarly, the third preset number can also be any integer satisfying actual scene requirements and less than the second preset number. The scope of protection required by the present disclosure is not limited in this respect.

[0071] For example, the timestamp list of a certain target barrage is attention_time_list = [1.5, 3, 4, 4.5, 5.5, 6], the current time t = 6, and the callback time interval of the eye tracking information is 0.5 seconds. In the case where the second preset number is 4 and the third preset number is 2, the four consecutive timestamps selected from the timestamp list are [4, 4.5, 5.5, 6]. Then, the time intervals between adjacent two timestamps are calculated as 0.5, 1, and 0.5, respectively, and the number of time intervals equal to the callback time interval 0.5 seconds is 2. In this case, it can be determined that the corresponding gaze duration of the target barrage meets the first preset standard.

[0072] In the process of watching a played video, the scrolling speed of each barrage may be different, which may cause the client user to be covered by a barrage with faster scrolling speed and "steal" the current eye focus while watching a certain barrage, but in fact the client still expects to continue watching the previously watched barrage. In addition, the client user may also cause the current eye focus to leave a certain barrage due to distraction or other reasons. By setting the second preset number and the third preset number, especially in the case where the third preset number is set to be less than the second preset number, the instantaneous defocus in the eye movement tracking process can be avoided.

[0073] According to some embodiments of the present disclosure, step S230 and / or step S430, adjusting the display attribute information of one or more target barrages, can further include: in response to determining that the corresponding gaze duration information of the target barrage no longer meets the first preset standard, adjusting the display attribute information of the target barrage to the previous display attribute information.

[0074] According to some examples, as described above, in the case where the first preset criterion is that the continuous time length of the user's gaze on the target barrage is equal to a preset time, when the client user shifts his gaze from the target barrage to a non-barrage area on the display screen, the user can no longer be interested in the target barrage, at which time the display attribute information of the target barrage can be adjusted to the previous display attribute information, so as to, for example, restore the original barrage display effect, for example, restore the default display font size, display font color, barrage running track, etc.

[0075] According to some examples, as described above, in the case where the first preset criterion is that the continuous time length of the user's gaze on the target barrage is equal to a preset time, when the client user shifts his gaze from the target barrage to a non-barrage area on the display screen, the user can no longer be interested in the target barrage, at which time the display attribute information of the target barrage can be adjusted to the previous display attribute information, so as to, for example, restore the original barrage display effect, for example, restore the default display font size, display font color, barrage running track, etc.

[0076] By restoring the display attribute of the target barrage as usual or to the adjusted display attribute when the gaze time on the target barrage does not meet the criterion, the display effect of the barrage on the client display screen can be adjusted in a timely manner during the constant change of the user's eye focus position, avoiding the barrage that is no longer the user's focus point still being highlighted, so that the barrage is displayed more clearly, which is conducive to improving the user's viewing experience.

[0077] According to some examples of the present disclosure, the step S230 of adjusting the display attribute information of one or more target barrages can include adjusting one or more of the following information of one or more target barrages: three-dimensional coordinate information, display size information, font information, animation effect information, and barrage track information.

[0078] As described above, the existing barrage is usually displayed on the 2D plane display area of the terminal device, and is usually displayed in a default or artificially set manner. However, in the case where a large number of barrages exist at the same time, merely using the above-mentioned default adjustment of barrage display manner can not be able to further distinguish and display the overlapping barrages.

[0079] Therefore, the barrage can be displayed by using a spatial 3D display technology. The spatial 3D technology refers to presenting content to a user in a realistic three-dimensional form by using a display device (e.g., a head-mounted display or a stereoscopic display) that employs advanced optical technology and special display devices and a rendering technology. The technology has a high-resolution, high-refresh-rate display screen, and combines precise image processing and projection algorithms to achieve a three-dimensional visual effect of each content element as in the real world. In this display mode, by adjusting the three-dimensional coordinate information, display size information, font information, animation effect information, and barrage trajectory information of the target barrage, barrages with different distances, different levels, different sizes, different animation effects, and different motion trajectories can be presented in the three-dimensional space, so that the user can not only feel the depth and stereoscopic effect of the real world, but also avoid the overlapping display of barrages, thereby obtaining a clearer viewing experience of the barrage.

[0080] According to some embodiments of the present disclosure, adjusting the three-dimensional coordinate information of the one or more target barrages and / or the display size information of the one or more target barrages can include: calculating a distance between each of the one or more target barrages and a current eye focus position indicated by the eye tracking information; and determining the three-dimensional coordinate information and / or the display size information of each target barrage based on the distance corresponding to the target barrage.

[0081] By calculating the distance between each target barrage and the current eye focus position, the target barrages can be sorted in descending order, and the smaller the distance, the higher the attention or interest of the user to the corresponding target barrage. Therefore, adjusting the three-dimensional coordinate information and / or the display size information of the target barrage based on the distance can distinguish the display of the target barrage, so that the target barrage that the user pays more attention to is displayed more clearly or prominently.

[0082] It will be understood that the calculation of the distance between each target barrage and the current eye focus position indicated by the eye tracking information can be the same as or similar to the calculation method used in step S326 described above. For the sake of brevity, it will not be described here again.

[0083] According to some embodiments of the present disclosure, determining the three-dimensional coordinate information and / or the display size information of each target barrage based on the distance corresponding to the target barrage can include: sorting the calculated distances corresponding to each target barrage; and determining the three-dimensional coordinate information and / or the display size information of each target barrage based on the sorting result.

[0084] According to some examples, the three-dimensional coordinate information of each target barrage can be determined based on the position of the target barrage in the descendingly sorted set, the distance between the display screen of the terminal device and the eyes of the user. For example, the Z-axis coordinate of each target barrage can be calculated by the following formula:

[0085] Z i =Z i0 +(i+1)*(Z0 / n)

[0086] wherein Z i represents the Z-axis coordinate of the i-th target barrage after being arranged in descending order (i=[0,n-1]), Z i0 represents the original Z-axis coordinate of the i-th target barrage, Z0represents half of the distance between the display screen of the terminal device and the user's eye (it will be understood that Z0is not limited to half of the distance between the display screen and the user's eye, but can also be one-third, two-thirds, or any suitable value of the distance), and n represents the total number of target barrages.

[0087] In the above manner, hierarchical arrangement of target barrage blocks can be achieved, so that the target barrage blocks closer to the current eye focus position are displayed closer to the user's eye, so that the user can more clearly watch the barrages of interest or interest, and improve the viewing experience.

[0088] According to some examples, the display size information of each target barrage can also be determined based on the position of the target barrage in the descendingly sorted set, the distance between the terminal device display screen and the user's eye. For example, the magnification ratio of each target barrage can be calculated by the following formula:

[0089] S i =1+(i+1)*(1 / n)

[0090] wherein S i represents the magnification ratio of the i-th target barrage after being arranged in descending order (i=[0,n-1]), 1 represents the original magnification ratio of the i-th target barrage (i.e., no magnification), and n represents the total number of target barrages.

[0091] Similarly, in the above manner, the target barrage blocks can be proportionally magnified, so that the target barrage blocks closer to the current eye focus position are displayed with a larger magnification ratio, so that the user can more clearly watch the barrages of interest or interest, and improve the viewing experience.

[0092] According to some embodiments of the present disclosure, adjusting the animation effect information of the one or more target bullet screens can include: for each of the one or more target bullet screens, configuring an interaction option for the target bullet screen, the interaction option being configured to be displayed on the client in association with the target bullet screen; obtaining gaze duration information of the client user on the interaction option of the target bullet screen; and in response to determining that the gaze duration information of the client user on the interaction option of the target bullet screen meets a second preset criterion, configuring an interaction animation effect for the target bullet screen to be displayed on the client in association with the target bullet screen.

[0093] According to some examples, the interaction option can be, for example, a like, a report, a reply, or the like, associated with the target bullet screen, so that when the user's eye focus is positioned on the target bullet screen, the user's interactive expression on the target bullet screen can be quickly realized through these interaction options.

[0094] According to some examples, the second preset criterion can be similar to the first preset criterion. For example, meeting the second preset criterion can be that the continuous duration of the user's gaze on the interaction option is equal to a preset time. For another example, meeting the second preset criterion can be that from a list of time stamps of the interaction option, a continuous fourth preset number of time stamps including the current time are selected; the time interval between each adjacent two time stamps in the fourth preset number of time stamps is calculated; and in response to determining that the number of time intervals equal to the callback time interval of the eye tracking information is not less than a fifth preset number, it is determined that the corresponding gaze duration information of the interaction option meets the second preset criterion. Wherein, the selection of the preset number can be the same as or similar to the selection of the preset number in the description of the first preset criterion above, and therefore will not be described here.

[0095] Accordingly, after displaying the interaction option of the target bullet screen, when the gaze duration of the user on the interaction option meets the preset criterion described above, the interaction animation effect for the interaction option can be displayed. Examples of the interaction animation effect include, but are not limited to, an animation effect of automatically displaying "+1" near the interaction option, an animation effect of automatically displaying a heart near the interaction option, changing the font color, font size of the interaction option, and / or changing the motion trajectory of the interaction option, etc.

[0096] By configuring the interaction option for the target bullet screen, the interactive experience of the client user when watching the video can be further enhanced. At the same time, by automatically displaying animation effects such as "+1", for example, the user's operation can be reduced while realizing the user's interactive expression on the target bullet screen.

[0097] According to some embodiments of the present disclosure, adjusting the font information can refer to adjusting the display font of the target barrage to be different from the display font of other barrages, for example, adjusting the display font of the target barrage to be Kai Ti, while the display font of other barrages is the default Song Ti. According to still some embodiments of the present disclosure, adjusting the barrage track information can refer to adjusting the motion track of the target barrage to be different from the motion track of other barrages, for example, adjusting the motion track of the target barrage to be reverse movement from left to right, while the motion track of other barrages is forward movement from right to left. It should be understood that any one of the above display attribute information or a plurality of display attribute information of the above display attribute information can be adjusted in combination according to the actual scene (for example, according to the number of barrages) to further highlight the target barrage to distinguish from other barrages.

As shown, the method 500 can include: step S510, obtaining eye tracking information of a client user watching a played video; step S520, determining a barrage subset within a first threshold distance range from current eye focus position information included in the eye tracking information from a plurality of barrages presented in the played video; step S530, calculating a distance between each barrage in the barrage subset and a current eye focus position indicated by the current eye focus position information, and determining the barrage as a target barrage in response to determining that the distance is less than a threshold distance; step S540, sorting the distance between each target barrage and the current eye focus position, and selecting a first preset number of target barrages with the smallest distance as updated target barrages; step S550, obtaining a timestamp list corresponding to the target barrage, updating the timestamp list corresponding to the target barrage to include a current time; step S560, selecting a latest continuous second preset number of timestamps from the timestamp list of the target barrage; step S570, determining whether the number of callback time intervals for each adjacent two timestamps is not less than a third preset number; step S580, in response to determining that the number of callback time intervals for each adjacent two timestamps is not less than the third preset number, sorting the calculated distance between the current eye focus position and each target barrage, and adjusting three-dimensional coordinate information and display size information of the target barrage based on the sorting result; and step S590, in response to determining that the number of callback time intervals for each adjacent two timestamps is less than the third preset number, abandoning to adjust the display attribute information of the target barrage.
