Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method, device, storage medium and electronic device for determining invalid exposure of a component. Background Art

[0002] In business iteration, APP (Application) data statistics and analysis plays a key role. It can support decision-making through data, deeply understand the essence of business, and maximize commercial value. In the data statistics and analysis process, data collection is the core link, and its purpose is to monitor the entire life cycle of users using product functions, understand the user value of functions and user preferences. Conventional APP data collection includes click data, display data, crash data, and consumption data. Among them, display data is particularly important, including page display and block (module, component) display, reflecting the number of times users see pages or blocks. However, in actual statistics, display data often differs from users' actual browsing behavior, especially in the content-rich and scrollable feed stream (a form of information flow content display, usually appearing on online platforms such as social media, news applications, and e-commerce platforms). Due to operational activities, advertising, and content similarity, users often quickly slide the list, resulting in aesthetic fatigue or difficulty in finding content of interest. In this sliding behavior, although the feed stream block component is exposed, the user may not actually see the content. Therefore, it is difficult to distinguish between effective exposure and invalid exposure. At present, the industry often uses tracking technology to collect exposure data of feed flow blocks, but for invalid exposure, it is necessary to optimize the data collection strategy: First, avoid pre-loaded exposure: In the feed pre-load strategy, the content loaded in advance may not be actually displayed, so it is necessary to avoid directly reporting exposure data when the block is initialized. Second, avoid incomplete block exposure: Traditional APP tracking strategies may record exposure when only 1 pixel of the block is exposed. In this case, it is difficult for users to distinguish the content of the block. Therefore, it is difficult to distinguish between valid and invalid exposures in the display data, especially when sliding quickly in the feed flow, resulting in statistical results that do not match the actual behavior.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0026] The disclosure below provides many different embodiments or examples to realize the different structures of the present application.

Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0027] According to a first aspect of an embodiment of the present application, a method for determining invalid exposure of a component is provided. Optionally, as follows: Figure 1 As shown, the above method includes:

[0028] S102, obtaining a gaze distance from the user's eyes to a display screen of a display device;

[0029] S104, collecting the moving distance and display duration of the target component within the target time period, wherein the starting time point of the target time period is the time point when the target component starts to be displayed on the display screen, and the ending time point of the target time period is the time point when the target component stops being displayed on the display screen;

[0030] S106, calculating the moving arc of the target component in unit time according to the gaze distance, the moving distance and the display time;

[0031] S108: When the moving arc of the target component within a unit time is greater than a first threshold, it is determined that the target component is invalidly exposed.

[0032] Alternatively, the feed stream may be filled with a large number of operational advertisements or inaccurately recommended content, which may cause users to become aesthetically fatigued or bored, or the feed may be scrolled quickly because most network users browse the current page as quickly as possible in the shortest time, which may affect the effective exposure of the feed stream component. Figure 2The F-shaped browsing pattern shown in the figure is a classic "F-shaped browsing pattern" that is usually formed when browsing long content on a web page or mobile phone. The eye movement is scanning the page rather than reading. The user first browses in a horizontal movement, usually in the upper part of the content area, forming the top bar of the F; next, the user moves the page down a little and scans in a second horizontal movement, which usually covers a shorter area than the previous movement, forming the lower horizontal line of the F; finally, the user scans the left side of the content vertically, which may be a quick, summary scan, which appears as a solid stripe on the eye tracking heat map. Sometimes the eye moves very quickly, creating a more spotty heat map. The last element constitutes the stem of the F. When people read a line of text, the movement of the human eye actually includes two basic movement phenomena: the movement of the eye itself (eye saccade) and fixation (relative stillness of the eye). The relative stillness of the eyes during the eye movement process is called fixation. The exact period of time required for the human visual system to perceive elements varies from individual to individual, so the time threshold required for fixation will also vary from individual to individual. The information people get when reading is mainly obtained during fixation, and the copy titles in the blocks in the feed flow are effectively understood by users in the fixation state. Eye saccades, also known as eye movements, are the movements of the eyeballs between fixation points. They are regular and voluntary movements controlled by the central nervous system, manifested as a sudden change in the fixation point or fixation direction of the eyeballs. Because of the anatomical structure of the retina and the limitations of visual acuity in the peripheral area of ​​the fovea, eye saccades are necessary in reading. In reading, a line of text viewed by the reader can be divided into three parts: the fovea (2° visual field in the center of vision), the parafovea (the area of ​​about 2° to 5° in the center of vision), and the peripheral area (all areas outside the parafovea). Although the visual acuity of the fovea is very high, the visual acuity of the parafovea is low, and the peripheral area is even worse. Therefore, in reading, the viewer must move his eyes to present the new reading content in the fovea visual area. Eye saccades are motor responses that require time to plan and execute. The latency of eye saccades is the time required to encode the position of the target in the visual area and induce eye movements, which is about 175 to 200ms. Eye saccade time refers to the time required for the eyes to actually move between two fixation points, which is closely related to the distance of the eye saccade. The greater the distance, the longer the duration. Smooth pursuit eye movements are eye movements in which people continuously visually track moving objects of interest in the environment. They are affected by perceptual factors such as visual information and eye movement feedback information obtained by individuals during the process, as well as high-level cognitive factors such as psychological representation and expectation. At the same time, the smooth pursuit eye movement process affects individuals' predictive eye tracking, catch-up saccades, spatial positioning, and contact time estimation, which involve the representation and prediction of the spatiotemporal characteristics of moving objects. Smooth pursuit eye movements are slower eye movements produced in order to keep the line of sight on the moving target object. They have the effect of compensating for the movement of the object to improve visual acuity. Relatively speaking, smooth pursuit eye movements are slower in speed, but the latency is not long.The latency of human smooth pursuit eye movement is 80ms to 150ms. People can usually track moving objects at 1 to 100 deg / s (degrees per second), but when the object speed exceeds 30deg / s, the speed of the eye movement will be significantly slower than the target movement speed. In order to compensate for this deviation, catch-up saccades are often accompanied during the smooth pursuit process. Smooth pursuit eye movement can be divided into two stages: open loop (the first 140ms after the target is presented) and closed loop. In the open loop stage, the eye movement is mainly driven by the imaging information of the target on the retina. In the first 20ms of the eye movement, the eyes continue to accelerate in the direction of the target movement and gradually approach the target speed within 20 to 100ms. In the process of eye tracking, that is, when the eye speed reaches the maximum value that matches the target speed, there will be a position and speed deviation between the eye and the target. The visual system usually uses two strategies, predictive tracking and catch-up saccades, to overcome this deviation. In summary, when a block in the feed stream appears on the screen in a sliding manner for less than 140ms, ordinary users cannot really see the content of the block. From the above principle, it can be seen that from the perspective of visual physiology, the eyes need to be in a static state or smooth tracking to see objects clearly, and the "eye jump" during fast sliding will affect the user's recognition effect. Therefore, fully considering the user's visual characteristics to optimize the exposure judgment logic is particularly critical to improve the accuracy of statistical data.

[0033] Optionally, in this embodiment, data related to the display device and the user are collected during the entire display process, including but not limited to the physical size (width, height) of the display screen, the gaze distance from the user's eyes to the display screen, the unique identifier of each component in the feed stream, the sampling time point, whether the component is visible, the relative position coordinates of the component corresponding to the display screen, the visible pixel leakage area of ​​the component, the original size area of ​​the component, etc. The sampling time point of the data is based on the screen refresh rate of the display device, that is, the number of times the screen display page content is refreshed within one second. Taking the screen refresh rate of 60Hz as an example, the upper limit of the time interval of each recorded sampling is 1 / 60 second, but due to the static state of the feed stream display, it is not necessary to record the data that is exactly the same as the previous time point.

[0034] Optionally, in this embodiment, before determining whether each component is invalid exposure, first determine whether it is visible. Specifically, the position and size of the target component are converted into the coordinate system of the display window. The frame of each view is defined based on the coordinate system of its parent view, and the coordinate system of the display window is the reference coordinate system of the entire screen. Through conversion, it can be ensured that the position of the component is consistent with the relative position of the display window, which is convenient for subsequent judgment. According to the rectangular area of ​​the converted target component view and the rectangular area of ​​the display window, check whether they have an intersection. If the two do not have an intersection, it means that the target component is completely out of the display range of the display window and the target component is invisible. If the area of ​​the intersection area is zero (for example, only one edge or one point intersects the two), the target component is still invisible because such an intersection area will not actually display any content. Even if the position and size of the target component meet the display conditions, it is necessary to further check its hidden attribute. If the hidden attribute of the subview is true, it means that the target component is explicitly set to a hidden state and will not be rendered on the screen. The target component is invisible. If the target component is determined to be invisible, the target component is determined to be invalid exposure.

[0035] Optionally, in this embodiment, the distance from the user's eyes to the display screen is monitored in real time through a sensor of the display device (such as an infrared camera, an optical sensor) or an external device (such as an eye tracker), which is called the gaze distance. The displacement of the target component on the display screen within the target time period is recorded, usually triggered by a sliding event, and the display duration is the time interval from the first display of the target component on the screen to the complete removal of the screen. The moving arc is an indicator calculated based on the gaze distance and the moving distance of the target component, and is used to measure the relative movement speed of the target component on the screen. When the moving arc of the target component per unit time exceeds the first threshold, the target component is deemed to be invalidly exposed. A high moving arc means that the component content slides too fast, and the user's eyes cannot capture and identify the specific content of the component in a short time. Therefore, this type of exposure has no actual browsing value.

[0036] Optionally, in this embodiment, the gaze distance from the user's eyes to the screen is combined with the movement distance of the target component, and the movement arc is calculated to comprehensively evaluate whether the user can clearly identify the component content. The judgment method combined with the gaze distance is closer to the actual user's browsing scenario, avoiding simple reliance on single indicators such as displacement or time, thereby improving the accuracy of judging invalid exposure of components, thereby accurately filtering invalid exposure data through multi-dimensional combination, and providing more realistic data support for subsequent advertising evaluation, operation strategy formulation, and recommendation algorithm optimization.

[0037] As an optional example, the moving distance of the target component in the target time period includes:

[0038] Collect the relative position coordinates of the target component at each sampling time point within the target time period, wherein the relative position coordinates are the relative position coordinates between the target position point of the target component and the display screen, and the target position point is any position point of the target component displayed in the display area of ​​the display screen at the first sampling time point;

[0039] According to the relative position coordinates of each group of adjacent sampling time points, the moving sub-distance of the target component corresponding to each group of adjacent sampling time points is calculated;

[0040] The sum of all moving sub-distances is determined as the moving distance of the target component within the target time period.

[0041] Optionally, in this embodiment, according to Figure 3 The coordinate axis diagram shown in the figure records the position information of the target component at each sampling time point relative to the display screen. The initial position point is the position of the target component in the display area of ​​the screen at the first sampling time point. For each group of adjacent sampling time points in the target time period, the moving sub-distance of the target component is calculated. If the target component slides up and down, the moving sub-distance is the moving distance of the two points in the vertical direction (Y coordinate) (if the target component slides up and down, the moving sub-distance is the moving distance of the two points in the vertical direction (Y coordinate)). The formula is:

[0042] Mobile distance (n) = |Y n+1 -Y n ∣;

[0043] Finally, all moving sub-distances are added together to obtain the total moving distance of the target component in the entire target time period.

[0044] Optionally, in this embodiment, the movement between adjacent time points is calculated point by point, and the movement trajectory of the target component is fully quantified to reflect its actual motion state on the screen. Combined with the movement distance information of the time series, invalid exposure caused by fast sliding can be effectively identified to avoid misjudgment caused by single static exposure data.

[0045] As an optional example, according to the gaze distance, the moving distance, and the display duration, calculating the moving arc of the target component in a unit time includes:

[0046] The moving arc of the target component within the target time period is calculated using the following formula:

[0047]

[0048] Among them, β is the moving arc of the target component in the target time period, D is the moving distance, and d is the gaze distance;

[0049] The moving arc of the target component per unit time is calculated using the following formula:

[0050]

[0051] Wherein, V is the moving arc of the target component per unit time, and t is the display duration.

[0052] Optionally, in this embodiment, the target component has two movement modes within the target time period, one is unidirectional movement and the other is multi-directional movement. If the movement mode of the target component within the target time period is unidirectional movement, the moving arc of the target component within the target time period can be calculated based on the moving distance of the target component within the target time period, or the moving arc of the target component within the target time period can be calculated based on the display length of the display screen. Specifically, when the moving arc of the target component within the target time period is calculated based on the moving distance of the target component within the target time period, the moving arc β of the target component within the target time period represents the angle formed by the target component on the screen when the user's line of sight moves. The specific formula (1) is as follows:

[0053]

[0054] Among them, Figure 4 As shown in the gaze diagram, D is the moving distance of the target component in the target time period, d is the gaze distance between the user's eyes and the display device screen, and 0.5×D assumes that the moving center of the target component is located at the midpoint of the observation angle, so half of the moving distance is taken to calculate the angle. By calculating β, the visual change angle corresponding to the movement of the target component on the screen can be obtained.

[0055] When calculating the moving arc of the target component within the target time period according to the display length of the display screen, the moving arc β of the target component within the target time period represents the angle formed by the target component on the screen when the user's line of sight moves. The specific formula (2) is as follows:

[0056]

[0057] Wherein, H is the display length of the display screen (if the target component is sliding left and right, it is the display width of the display screen), and d is the gaze distance between the user's eyes and the display device screen.

[0058] To further quantify the arc movement of the target component per unit time, the following formula (3) is used:

[0059]

[0060] Wherein, V is the moving arc of the target component per unit time, and t is the display time of the target component on the screen.

[0061] Optionally, in this embodiment, the distance for unidirectional sliding can be the screen height, and the distance for repeated multi-directional sliding is calculated by accumulating the moving distance of each collected coordinate. For example, when sliding up and down, Figure 5 As shown in the schematic diagram of repeated multi-directional sliding, when sliding in multiple directions repeatedly, the total moving distance of the current block is the accumulated difference of the Y coordinate of the block. All data of the data set of the single exposure of the current block are traversed in time order, and the Y coordinate distance of the sampled data moving forward and backward is obtained one by one (ABCD). Taking the A sampling point (XA, YA) and the B sampling point (XB, YB) as an example, the moving distance = |YB-YA|. Similarly, according to the above calculation rules, the radian V moved per unit time of repeated multi-directional sliding is calculated. If the radian moved per unit time during the sliding of the current block component across the screen is greater than the upper limit of the radian per second of eye movement smooth tracking, the current block component is deemed to be invalid exposure.

[0062] As an optional example, before calculating the moving arc of the target component per unit time according to the gaze distance, the moving distance, and the display duration, the method further includes:

[0063] According to the relative position coordinates of the target component at each sampling time point within the target time period, the leakage area of ​​the target component at each sampling time point is obtained;

[0064] The maximum area among all leakage areas is determined as the target leakage area of ​​the target component within the target time period;

[0065] Obtaining the display area of ​​the display screen, and calculating the display percentage of the target component within the target time period according to the target leakage area and the display area;

[0066] When the displayed percentage is less than or equal to the second threshold, the target component is determined to be invalidly exposed.

[0067] Optionally, in this embodiment, before judging the target component according to the moving arc of the target component in a unit time, it is possible to judge whether it is invalid exposure by analyzing the leakage of the target component. Specifically, within the target time period, the relative position coordinates of the target component and the display screen at each sampling time point are collected, and based on the relative position coordinates, the leakage area (actual visible area) of the target component at each sampling time point is calculated, which reflects the effective display area of ​​the target component at that time point. The leakage areas of all sampling time points are traversed, and the maximum leakage area is selected as the target leakage area of ​​the target component, which represents the maximized visible range of the target component in the entire time period, and can more accurately measure its display effect. The total display area of ​​the device screen is obtained for normalization calculation, and the calculation formula (4) of the display percentage is:

[0068]

[0069] This percentage reflects the visibility of the target component relative to the total screen area. A second threshold (such as 10% or other specific ratio) is set to indicate the minimum standard for effective display. When the display percentage of the target component is less than or equal to the second threshold, the target component is deemed to be invalidly exposed, that is, the user cannot fully perceive its content.

[0070] Optionally, in this embodiment, by comparing the leakage area with the display area, it is possible to avoid relying solely on the position or time of the target component to ensure that the invalid exposure judgment is more scientific. Combined with the maximum leakage area, various display conditions (such as partial occlusion, sliding, etc.) in dynamic scenes are adapted to greatly improve the robustness of the algorithm.

[0071] As an optional example, after calculating the moving arc of the target component per unit time according to the gaze distance, the moving distance, and the display duration, the method further includes:

[0072] When the moving arc of the target component in a unit time is less than or equal to the first threshold, determining the static duration of each static time period of the target component within the target time period according to the relative position coordinates of the target component at each sampling time point;

[0073] When the static durations of all static time periods are less than or equal to the third threshold, it is determined that the target component is invalidly exposed.

[0074] Optionally, in the visual system of the human eye, the gaze state is when the eyes remain relatively still, and humans mainly perceive and understand elements through the information during the gaze period. Effective browsing of copywriting, titles or pictures requires the eyes to focus for a certain period of time. Studies have shown that most effective reading and perception occur during the gaze period of 200 to 300 milliseconds. Therefore, in this embodiment, the static time is used to analyze whether the user has enough gaze time to effectively browse the content of the target component. Specifically, the gaze distance and movement distance of the target component are used to calculate its movement arc per unit time. If the movement arc is less than or equal to the first threshold, it is considered that the target component is relatively stable and may be in a static state. In the target time period, the relative position coordinates of the target component at each sampling time point are obtained. If the movement distance of the continuous sampling points is close to 0 (or lower than the set static judgment range), it is marked as a static time period. According to the sampling time point, the duration of each static time is calculated. The third threshold is set as the minimum gaze time, for example, 100 to 300 milliseconds recommended by academic research is used as the shortest time required for users to effectively perceive component content. Traverse all static time periods. If the static time of each period is less than or equal to the third threshold, it is judged that the user has not fully focused on the target component, which is invalid exposure. Combining the static time with the focus threshold, it is clear to distinguish between short glances and real effective focus, and reduce the misjudgment of invalid exposure. Through the analysis of static time, based on the physiological mechanism of human eye focus, it can be closer to the actual browsing experience of users.

[0075] As an optional example, after determining the static duration of each static time period of the target component within the target time period, the method further includes:

[0076] When the static time length of the target static time period is greater than a third threshold, obtaining the eye state of the user in the target static time period, wherein the target static time period is any static time period among all the static time periods, and the eye state includes a gaze state and a non-gaze state;

[0077] When the user's eye state is in a non-attention state during the target static time period, the target component is judged to be invalidly exposed.

[0078] Optionally, human eye gaze is a necessary condition for obtaining visual information. The static state alone cannot prove whether the user is paying attention to the content. In combination with the eye state, the user's real behavior can be judged more accurately. In some cases, although the component is static, the user's attention is not focused. For example, the user may view other content during the static time period, resulting in ineffective browsing behavior. Therefore, in this embodiment, in the visual system of the human eye, within the target time period, the moving arc of the target component is close to zero or within the set range, and the component can be considered to be in a static state, and each continuous static time interval is a static time period. Traverse all static time periods, and retain the time period with a static duration greater than the third threshold as a candidate target static time period. According to the user's eye tracking data, it is divided into the following two states: gaze state: the user's line of sight coincides with the target component and lasts for a certain period of time; non-gaze state: the user's line of sight is not focused on the target component, and may be viewing other areas or not focusing on the screen. The user's line of sight and gaze time can be collected in real time through an eye tracking device or a built-in sensor. If the user's eye state in the target static time period is a non-gaze state, the target component is not really focused by the user, so the target component is judged as invalid exposure. Combining the user's eye state with the still time can effectively avoid misjudgment due to line of sight deviation and further improve the recognition accuracy of invalid exposure.

[0079] As an optional example, after obtaining the eye state of the user in the target static time period, the method further includes:

[0080] When the eye state of the user in the target static time period is a gaze state, obtaining the position of the gaze point of the user's eyes in the target static time period;

[0081] When the position of the gaze point is not within the display area of ​​the target component, the target component is judged to be invalidly exposed.

[0082] Optionally, although the user's gaze state indicates that they are paying attention to the screen, it cannot directly indicate that they are paying attention to the target component. Through accurate judgment of the gaze point position, invalid exposure of the target component when the user is gazing at other areas (such as advertisements, other content modules) can be eliminated. The comprehensive judgment of the static state, gaze state and gaze point position can more comprehensively reflect the user's true attention distribution. Therefore, in this embodiment, the target component is judged as static by the system during the target static time period, and the user's eye state is a gaze state. At this time, the specific position of the user's gaze point can be further analyzed. The gaze point is the projection coordinate of the user's line of sight on the display screen during the target static time period, usually expressed as a pixel point (x, y) of the screen. The gaze point position of the user's line of sight can be recorded in real time through an eye tracking device or a built-in sensor. The display area of ​​the target component on the screen can be determined by the boundary coordinates of the component, such as the coordinates of the upper left corner and the lower right corner of the rectangle (x1, y1) and (x2, y2). If the coordinates of the gaze point are within the display area of ​​the target component (satisfying x1≤x≤x2 and y1≤y≤y2), it means that the user is indeed looking at the target component. If the coordinates of the gaze point are not within the display area of ​​the target component, the user's gaze behavior is not focused on the target component, that is, the target component is not effectively focused, and the target component is judged as invalid exposure.
