Description

Technical Field

[0001] The present invention relates to the field of image processing technology and can also be used in the financial field, and in particular to a document display method and device. Background Art

[0002] With the development of the Internet, more and more applications (apps) have launched the function of annual user reports to display statistics on users' main data and usage habits in the past year.

[0003] The most common approach for annual reports is to use a page-flipping solution. Whether flipping left or right or up or down, each page is the same size as the user's phone screen. This results in poor transition quality and continuity, and users need to swipe a long distance to turn the page, resulting in a poor user experience.

[0004] Specifically, the current page-turning solution is limited by screen size, requiring each report page to be displayed one screen at a time. This results in poor page continuity during page turning. If the themes of adjacent pages are not well designed, the display will be abrupt due to the conflicting themes, resulting in a poor user experience.

[0005] This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. No statement herein is admitted to be prior art by virtue of its inclusion in this section. Summary of the Invention

[0075] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0076] The information collected in the technical solution of the present invention is information and data authorized by the user or fully authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of the relevant data comply with the relevant laws, regulations and standards of the relevant countries and regions, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0077] The acquisition, transmission, storage, use, and processing of data in the technical solution of the present invention comply with the relevant provisions of national laws and regulations.

[0078] It should be noted that in the embodiments of the present invention, certain software, components, models and other existing solutions in the industry may be mentioned. They should be regarded as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of the present invention, but it does not mean that the inventor has or will necessarily use the solution.

[0079] The document display method provided by the embodiment of the present invention is executed by a subject including but not limited to a computer.

[0080] In order to solve the above technical problems, the present invention provides a document display method, such as Figure 1 As shown, the document display method provided by the present invention includes:

[0081] S11. Monitor a user screen sliding event, and determine real-time position information of a user touch point according to the user screen sliding event.

[0082] In step S11, an event listener can be set in the application to listen for user screen sliding events. Specifically, an event processing function can be bound to the touch event on the screen; when the user starts to touch the screen, the event listener will capture the coordinates of the touch point, and these coordinates can be expressed in a two-dimensional coordinate system with the upper left corner of the screen as the origin; as the user's finger moves on the screen, the event listener will continue to capture new touch point coordinates and update the position information in real time, thereby capturing the starting point, end point and moving path of the user's finger on the screen.

[0083] Specifically, you can use methods provided by specific application programming interfaces (APIs) or frameworks to register event listeners and handle events. For example, in Android development, you can use the onTouchEvent method to listen for and handle touch events; in iOS (a mobile operating system developed by Apple) development, you can use the UIPanGestureRecognizer method to recognize and respond to slide gestures; and in World Wide Web (Web) development, you can use the addEventListener method to listen for touchstart events, touchmove events, and touchend events.

[0084] S12. Determine the rotation angle of the turntable image based on the real-time position information of the user touch point, wherein the rotation center of the turntable image is located on or outside the boundary line of the screen display area, and the rotation angle of the turntable image is compared to the original rotation angle when the turntable image is not rotated.

[0085] In step S12, the rotation center of the turntable image is located on the boundary line of the screen display area or outside the boundary line of the screen display area. When the turntable image rotates, the turntable image rotates into the image in the screen display area as the background image of the current document display page. In addition, in this step, the rotation angle of the turntable image is calculated in real time based on the real-time position information of the user's touch point, and the real-time calculated rotation angle is provided to the subsequent step S13. The real-time calculated rotation angle is compared to the original rotation angle when the turntable image does not rotate. In other words, the real-time calculated rotation angle is compared to the rotation angle of the turntable before the user sliding screen event is monitored in step S101.

[0086] S13. According to the rotation angle of the turntable image, the turntable image is rotated and the document page content corresponding to the turntable image displayed in the screen display area is rotated or displayed, wherein the turntable image is used as the background image of the document, and each time the turntable image rotates a specific angle, a new page content is displayed in the screen display area.

[0087] In step S13, the turntable image serves as the background image for all pages of the document. Different pages use different areas of the turntable image as the background image. These background images may have overlapping areas or may be completely different, depending on the radius of the turntable image, the position of the rotation center, and the setting of the specific angle. Each time the turntable image rotates by the specific angle, a new page of content is displayed in the screen display area. In other words, each time the turntable image rotates by the specific angle, the document is turned over once, and a new page of content is displayed in the screen display area.

[0088] However, when the rotation angle of the turntable image determined based on the real-time position information of the user's touch point is less than the specific angle, the turntable image can be rotated according to the rotation angle of the turntable image. At the same time, the document page content corresponding to the turntable image displayed in the screen display area is controlled in real time to rotate synchronously, so that the page turning operation can have a good transition effect.

[0089] The document display method provided by an embodiment of the present invention determines the rotation angle of the turntable image by monitoring the user's screen sliding event, and then synchronously rotates the turntable image and the document page content corresponding to its parts according to the rotation angle. In this way, the page turning is controlled by the turntable, and all pages of the document are distributed on the turntable, so that the page design style can be easily unified, which effectively solves the problems of poor transition effect and continuity in the page turning process.

[0090] like Figure 2 As shown, in some embodiments, step S11 includes:

[0091] S111 . Monitoring an event in which a user starts touching the screen, and determining, according to the event in which the user starts touching the screen, first position information of a touch point when the user starts touching the screen.

[0092] S112: Monitor an event that the user is sliding the screen, and determine real-time position information of the user's touch point based on the event.

[0093] S113: Monitor an event in which the user stops touching the screen, and determine, according to the event in which the user stops touching the screen, second position information of the touch point when the user stops touching the screen.

[0094] Specifically, step S111 involves capturing the event when the user first touches the screen. Taking mobile application development as an example, this can be achieved by listening to the touchstart event. When the user places their finger on the screen, the event is triggered, and the initial position information of the touch point can be obtained, including the X and Y coordinates. In step S112, after the user starts touching the screen, if they start moving their finger on the screen, the touchmove event is triggered. The real-time position of the user's finger moving on the screen can be tracked by listening to this event. In step S113, when the user removes his finger from the screen, the touchend event is triggered. The final position information of the user's finger when it leaves the screen is captured. This can be used to determine the end of the touch operation.

[0095] like Figure 3 As shown, in some embodiments, step S12 includes:

[0096] S121 : Determine a real-time rotation angle of the turntable image according to the real-time position information of the user touch point and the first position information.

[0097] S122. Determine a final rotation angle of the turntable image based on the second position information of the touch point when the user stops touching the screen and the first position information, so as to turn the document to the left or right according to the final rotation angle.

[0098] Specifically, in step S121, the system will monitor the position of the user's touch on the screen in real time, and based on this position information and a pre-set reference position (first position information), calculate the real-time rotation angle of the turntable image, and pass the real-time rotation angle to step S13 in real time. In step S122, when the user stops touching the screen, the system will record the final position of the user's touch point (second position information), compare it with the first position information again, and pass this comparison result (rotation angle of the turntable image) to the subsequent step S13 in real time. Step S13 determines the final rotation angle of the turntable image based on this comparison result. This angle will determine whether the document is turned page, turned left or turned right.

[0099] like Figure 4 As shown, in some embodiments, step S13 includes:

[0100] S131 . Rotate the turntable image and the page content corresponding to the turntable image in the screen display area according to the real-time rotation angle of the turntable image.

[0101] S132: Rotate the turntable image according to the final rotation angle of the turntable image and display the page content corresponding to the turntable image displayed in the screen display area after the rotation.

[0102] Specifically, in step S131, after the system calculates the rotation angle of the carousel image in real time based on the user's touch action, it rotates the carousel image itself and the page content corresponding to the carousel image within the screen display area. This means that as the user slides the screen, the carousel image and the page content will rotate accordingly, simulating a page turning action.

[0103] In step S132, after the user completes the page-turning action, the system performs a final rotation of the turntable image based on the final rotation angle of the turntable image. After the rotation is complete, the system displays the page content corresponding to the turntable image in the screen display area. This ensures that the user sees the correct page content after turning the page, and that the display of the page content is consistent with the rotation state of the turntable image. Furthermore, if the user's page-turning action does not meet the page-turning conditions, step S132 will synchronously rotate the turntable image and the corresponding page content back to the initial angle.

[0104] In some embodiments, the rotation center of the turntable image is located at the center of the bottom boundary line of the screen display area, the real-time position information includes the horizontal coordinate of the real-time position, and the first position information includes the horizontal coordinate; in this case, Figure 5 As shown, step S121 includes:

[0105] S1211 : Calculate the difference between the real-time horizontal coordinate of the user's touch point and the horizontal coordinate of the touch point when the user starts touching the screen.

[0106] S1212: Calculate the ratio between the difference and the width of the screen display area.

[0107] S1213: Determine a real-time rotation angle of the turntable image according to the ratio and the specific angle.

[0108] Specifically, the system calculates the difference between the horizontal coordinate of the current touch point and the horizontal coordinate of the initial touch point in real time. This difference represents the horizontal distance the user's finger has moved. The system then compares this difference with the width of the screen display area and calculates the ratio between the difference and the screen width. This ratio is a dimensionless value that represents the ratio of the distance the user's finger has moved relative to the entire screen width. Finally, the system determines the real-time rotation angle of the turntable image based on this ratio and the angle the turntable image needs to rotate each time the document page is turned.

[0109] For example, if the screen width is W, the horizontal coordinate difference of the user's finger movement is X, and the angle the turntable needs to rotate for each page is A, then the real-time rotation angle θ can be calculated using the following formula: θ = (X / W) × A = (W / X) × A. This ensures that the rotation angle of the turntable image is proportional to the user's finger movement, providing an intuitive and responsive interactive experience.

[0110] In some embodiments, the second position information includes a horizontal coordinate; in this case, Figure 6 As shown, step S122 includes:

[0111] S1221. Calculate the difference between the horizontal coordinate of the touch point when the user stops touching the screen and the horizontal coordinate of the touch point when the user starts touching the screen.

[0112] S1222: If the absolute value of the difference is greater than one-quarter of the width of the screen display area, continue to determine whether the difference is greater than 0.

[0113] S1223: If the difference is greater than 0, determine that the turntable image is rotated to the right and determine a final rotation angle of the turntable image according to the specific angle.

[0114] Specifically, when the user stops touching the screen, the system calculates the difference between the horizontal coordinate at the end and the horizontal coordinate when the user starts touching the screen. This difference reflects the total distance the user's finger has moved in the horizontal direction of the screen. Next, it is determined whether the absolute value of this difference is greater than one-quarter of the width of the screen display area. This threshold is set to one-quarter of the screen width to trigger the page turning operation. If the absolute value of the difference is greater than this threshold, the next judgment is carried out: If the difference is greater than 0, that is, the user is sliding from left to right, the system will determine that the turntable image needs to be rotated to the right. Then, the system will determine the specific rotation angle based on the angle that the turntable image needs to rotate each time the document turns a page.

[0115] This calculation ensures that when the user swipes from left to right, the carousel image rotates to the right, creating the effect of turning the page to the right. If the user swipes from right to left, the corresponding logic will determine that the carousel image rotates to the left, creating the effect of turning the page to the left.

[0116] like Figure 7 As shown, in some embodiments, after step S1221, the document display method provided by the present invention may further include the following steps:

[0117] S1224: If the absolute value of the difference is less than or equal to one-quarter of the width of the screen display area, use the original rotation angle of the turntable image as the final rotation angle of the turntable image.

[0118] S1225. If the absolute value of the difference is greater than one-quarter of the width of the screen display area and the difference is less than 0, determine that the turntable image rotates to the left and determine a final rotation angle of the turntable image according to the specific angle.

[0119] Specifically, this embodiment supplements the page-turning logic of step S122 in the above embodiment. Specifically, if the absolute value of the difference between the horizontal coordinate when the user stops touching the screen and the horizontal coordinate when they start touching the screen is less than or equal to one-quarter of the width of the screen display area, this means that the user's sliding distance is insufficient to trigger a page-turning operation. In this case, the system will restore the original rotation angle of the turntable image and will not turn the page.

[0120] If the absolute value of the difference is greater than one-quarter of the screen's width and the difference itself is less than 0 (i.e., the user is swiping from right to left), the system determines that the carousel image needs to be rotated left. The system then determines the specific rotation angle based on the angle the carousel image needs to rotate each time the document is turned, achieving the effect of turning the page to the left.

[0121] To better understand the present invention, the document display method provided by the present invention is described in detail below through a specific embodiment.

[0122] Given a turntable base map on the page, its radius is the screen height and the center is at the bottom center of the screen. Figure 8 As shown in the figure, the turntable can be controlled to rotate around the center by sliding left and right in the screen display area. Assuming that the annual report has 8 pages, the turntable can be divided into 8 equal parts by the center of the circle, so that the angle of switching each part is 45 degrees, and each page content is placed in each equal part, as shown in the figure. Figure 9 As shown in the figure, when the user swipes the screen left or right, the turntable rotates to follow the gesture. When the user begins to touch the screen, the distance from the touch point to the left edge of the screen is recorded as x1. When the user stops touching the screen, the distance from the touch point to the left edge of the screen is recorded as x2. The absolute value of x2-x1, denoted as x, is the horizontal distance the user swipes on the screen. The difference between x1 and x2 determines whether the user swiped left or right. Next, determine whether x is greater than one-quarter of the screen width. If so, switch pages; if not, remain on the original page.

[0123] Based on the above technical principles, swiping left or right on the screen can rotate the carousel and switch pages accordingly. Because all pages are on the carousel, the continuity and transition effects when switching between pages are very good, and the theme style of each annual report page can be designed to be consistent.

[0124] The following is a detailed introduction to the specific implementation process of this solution.

[0125] Step 1: Define the number of pages to be displayed and calculate the average rotation angle c1 of each page. c represents the current rotation angle of the turntable, which is initialized to 0 degrees, and the screen width is recorded as w.

[0126] Step 2: Listen for the user's touch event. Record the distance from the touch point to the left edge of the screen as x1 when the user starts touching the screen.

[0127] Step 3: Monitor the event that the user is sliding the screen (this event will be continuously triggered after the user touches the screen), and record the distance from the current touch point to the left edge of the screen as x2 in real time. Calculate the result of x2-x1 and record it as x. Then calculate (x / w)*c1 to get the angle c2 that the turntable needs to rotate. Then set the current real-time rotation angle of the turntable to: c+c2.

[0128] Step 4: Listen for the user to end touching the screen event (this event will be triggered when the user's finger leaves the screen), and record the distance from the current touch point to the left edge of the screen as x2. Calculate the result of x2-x1 and record it as x. Determine whether the absolute value of x is greater than w / 4. If it is greater than, then determine whether x is greater than 0. If x is less than 0, it means that the user swiped to the left, then the current turntable rotation angle is set to: c = c-c1, and switch to the next page. If x is greater than 0, it means that the user swiped to the right, then the current turntable rotation angle is set to: c = c+c1, and switch to the previous page. If the absolute value of x is less than or equal to w / 4, then the current turntable rotation angle is set to: c, and remain on the original page.

[0129] The screen display system used to implement the above solution mainly includes the following modules:

[0130] The parameter definition module defines the required constants and variables. Specifically, it first determines the number of pages in the annual report, n, and then calculates the average rotation angle per page, c1 = 360 / n. c represents the current rotation angle of the turntable, which is initialized to 0 degrees, and w represents the screen width. It then listens for the user's initial touch event on the screen and records the distance from the touch point to the left edge of the screen as x1.

[0131] The first monitoring module is used to monitor user screen swipes and control the rotation of the turntable. Specifically, it monitors screen swipe events, records the swipe position x2 in real time, and calculates the swipe distance x using x1 in the parameter definition module. It then calculates (x / w)*c1 to determine the desired turntable rotation angle c2. The turntable's current real-time rotation angle is then set to c+c2. This allows for rotation to follow gestures.

[0132] The second monitoring module is used to monitor when the user ends a swipe and determine the final page displayed. Specifically, it monitors for the user's swipe-end event, records the current swipe position x2, and calculates the total swipe distance x using x1 from module one. It then determines whether the absolute value of x is greater than one-quarter of the screen width w in module one. If so, it then determines whether x is greater than 0. If x is less than 0, it indicates a left swipe. In this case, the current turntable rotation angle is set to c = c - c1, switching to the next page. If x is greater than 0, it indicates a right swipe. In this case, the current turntable rotation angle is set to c = c + c1, switching to the previous page. If the absolute value of x is less than or equal to w / 4, the current turntable rotation angle is set to c, remaining on the previous page. Because the turntable in module two has already rotated a certain angle to follow the gesture, any reset turntable rotation angle in this module will differ significantly from the angle in module two. In this case, a transition animation can be used to transition the turntable from the rotation angle in module two to the rotation angle in this module.
