[0037] Embodiment 1

[0038] Figure 1 This is a flowchart of a canvas moving method provided in the first embodiment of the present application. The present embodiment of the present application can be applied to the case of moving the canvas of a whiteboard. The method can be executed by a canvas moving device, which can be implemented in the form of hardware and / or software, and the canvas moving device can be configured in an electronic device. Figure 1 As shown, the method includes:

[0039] S110: Determine distribution data of the recorded content on the canvas, and determine whether the canvas meets the moving condition according to the distribution data.

[0040] The canvas is an electronic canvas in an electronic whiteboard. The recorded content is the content recorded on the canvas by a user through writing or drawing, which can be in the form of text, symbols, or drawings. The distribution data is used to indicate the position distribution of the recorded content on the canvas.

[0041] In an embodiment of the present application, if a touch operation of a user on the display screen is detected, the pixel point corresponding to the electronic canvas is determined according to the coordinates of the position point where the touch operation is detected, and the canvas block where the pixel point is located is determined, and the marking data of the block is updated. The block can be obtained by dividing the pixel points on the canvas. For example, the entire pixel point range of the canvas is determined according to the resolution of the display screen. If the resolution of the display screen is 3840*2160, the entire pixel point range of the canvas is 3840*2160, and the entire pixel point range can be divided into blocks to obtain 160*90 blocks. If there is no recorded content in the block, the marking data can be set to initial data, such as 0. If there is recorded content in the block, the marking data is updated to preset data, such as 1, so as to mark whether there is recorded content in the block. If the pixel point in the block detects that there is written recorded content, the block is updated to preset data. In addition, according to the time when the recorded content is written in the block, the timestamp corresponding to the block can be recorded to mark the writing time of the recorded content. If the user deletes the recorded content, the marked data of the blocks corresponding to the deleted recorded content are restored to the initial data, and the timestamp corresponding to the blocks is deleted.

[0042] For example, Figure 2 As shown in FIG. 1 , if the user draws a straight line horizontally on the canvas, the marking data of the blocks through which the horizontal line passes is updated to the preset data, and the time when the horizontal line is drawn on the block is recorded, that is, Figure 2 time1-time7 in. Figure 3 As shown in the figure, if the user draws another vertical line and it intersects with the horizontal line drawn before, the marking data of the block through which the vertical line passes is updated to the preset data, and the timestamp of the block through which the vertical line passes is updated according to the time when the vertical line is drawn on the block, that is, time8-time13. Figure 3 In the time5-time7 corresponding block, the recorded content is cleared from the canvas after the user's deletion operation is detected, and the mark information of the corresponding block is updated to the initial data, and the corresponding timestamp is deleted, such as Figure 4 If the horizontal line deleted by the user only occupies part of the pixels in the block, and there are still horizontal lines in the other part of the pixels, the marking data and timestamp of the block will remain unchanged until the recorded content of all the pixels in the block is completely deleted, the marking information of the corresponding block is updated to the initial data, and the corresponding timestamp is deleted, as shown in Figure 5 shown.

[0043] Exemplarily, the distribution data of the content recorded on the canvas can be determined based on the marked data of the blocks on the canvas, for example, the number of blocks whose marked data is preset data is calculated, and whether the content recorded on the canvas has filled the canvas is determined based on the number of blocks whose marked data is preset data and the total number of blocks in the canvas. The distribution data of the content recorded on the canvas can also be determined based on the marked data of the blocks on the canvas and the corresponding timestamps, for example, the position of the distribution of the content recently recorded by the user is calculated, so as to determine the canvas area that the user tends to record recently.

[0044] In an embodiment of the present application, it is possible to determine whether the canvas meets the moving condition based on the distribution data, thereby determining whether to execute the subsequent canvas translation step. Specifically, it is possible to determine that the canvas meets the moving condition when the distribution data determines that the recorded content occupies a relatively large area on the canvas, resulting in no more blank areas for the user to record. It is also possible to determine that the canvas meets the moving condition when the distribution data determines that there are more recorded contents in a part of the canvas, resulting in no more blank areas for the user to record. Through the above scheme, the recorded content on the canvas can be automatically detected, thereby automatically determining whether the canvas meets the moving condition, and automatically executing the subsequent translation step when the canvas meets the moving condition.

[0045] S120. If the canvas meets the moving condition, the reference direction of the canvas movement is determined according to the marking data of the blocks on the canvas and the corresponding timestamps; wherein the marking data is used to indicate whether there is recorded content on the blocks, and the timestamp is used to indicate the recording time of the recorded content.

[0046] Among them, the reference direction of the canvas movement can be used to assist in determining the direction of the canvas movement. The reference direction of the canvas movement can reflect the user's recording tendency and reflect the overall recording direction of the recorded content on the canvas. For example, it can reflect whether the user tends to record from the left side of the canvas to the right side of the canvas, or from the left side of the canvas to the right side of the canvas. The user's tendency is not limited to the trajectory of the same stroke, and can be the overall distribution direction of the recorded content when the user records on the canvas. In an embodiment of the present application, if the canvas meets the moving conditions, the reference direction of the canvas movement is determined. Specifically, the reference direction of the canvas movement can be determined based on the marking data of the blocks on the canvas and the corresponding timestamps. When the marking data is updated to the preset data, it means that the recorded content is recorded on the block, and the timestamp indicates the recording time of the recorded content. The recording order of the recorded content is determined according to the recording time, and then the reference direction of the canvas movement is determined.

[0047] Exemplarily, if the timestamps corresponding to the blocks whose timestamps at the preset time change from left to right are getting closer to the current moment, it can be determined that the reference direction of the canvas movement corresponding to the timestamps at the preset time is from left to right. In addition, the reference direction of the canvas movement can also be determined based on the position of the blocks corresponding to the timestamps closer to the current moment in the canvas. For example, if the blocks corresponding to the timestamps closer to the current moment are on the right side of the canvas, it can be determined that the reference direction of the canvas movement is from left to right.

[0048] S130: Determine a canvas movement direction according to a reference direction of the canvas movement, and move the canvas based on the canvas movement direction.

[0049] Exemplarily, the direction of canvas movement can be determined based on the principle that there will be more blank areas for the user to record when the user continues to record along the reference direction of the canvas movement after the movement. For example, the opposite direction of the reference direction of the canvas movement is used as the canvas movement direction. The direction of the canvas movement at a preset angle to the opposite direction of the reference direction of the canvas movement can also be used as the canvas movement direction. For example, the opposite direction of the reference direction of the canvas movement is from right to left, and the canvas movement direction can be from the lower right to the upper left. The reference direction of canvas movement can reflect the user's recording habits. The canvas movement direction is determined according to the reference direction of the canvas movement, and the canvas is moved based on the canvas movement direction. More blank areas are displayed through the canvas movement to meet the space requirements of the user when continuing to record according to the reference direction of the canvas movement.

[0050] The amplitude of the canvas movement can be determined according to the actual situation, for example, the canvas can be moved along the direction of the canvas movement by half, one third or one quarter of the maximum length of the canvas each time. The amplitude of the canvas movement can also be determined according to the distribution data of the recorded content on the canvas. For example, the recorded content is concentrated on the four-fifths of the right side of the canvas, and the one-fifth of the left side of the canvas has no recorded content. If the canvas moves from right to left, one-fifth of the canvas can be moved from right to left to remove the one-fifth of the left side without recorded content, and increase the one-fifth of the right side to allow users to record.

[0051] In the embodiment of the present application, the timing for moving the canvas can be when the user's touch operation on the canvas disappears and no touch operation on the canvas is detected again within a time threshold after the user's touch operation on the canvas disappears, then the canvas is moved to avoid moving the canvas when the user is recording on the canvas, which affects the user's normal recording and user experience. The time threshold can be determined according to actual conditions, for example, 1 second.

[0052] In an embodiment of the present application, moving the canvas based on the canvas movement direction includes:

[0053] If a user movement operation on the canvas is detected, then whether there is an operation of adding or deleting recorded content on the canvas is detected;

[0054] If it exists, when the canvas meets the translation condition, the canvas is moved based on the canvas movement direction.

[0055] Exemplarily, if a user moves the canvas, in order to avoid affecting the user experience, the canvas is not moved regardless of whether the canvas meets the moving conditions at this time, and the canvas continues to be detected for adding or deleting recorded content. If an adding or deleting operation of recorded content is detected on the canvas, it means that the user continues to record after moving it by himself, and the steps S110-S130 are continued for the canvas moved by the user, so as to fully consider the user's wishes, regard the user's operation as the highest priority, and improve the user experience. And avoid the user moving the canvas while the canvas is automatically moved, resulting in repeated and disordered movement.

[0056] After the canvas is moved based on the canvas moving direction, steps S110 to S130 are continued to be executed for the currently displayed canvas.

[0057] The technical solution of the embodiment of the present application determines the distribution data of the recorded content on the canvas, and determines whether the canvas meets the moving conditions based on the distribution data; if the canvas meets the moving conditions, the reference direction of the canvas movement is determined based on the marking data of the blocks on the canvas and the corresponding timestamp; wherein the marking data is used to indicate whether there is recorded content on the blocks, and the timestamp is used to indicate the recording time of the recorded content; the canvas movement direction is determined based on the reference direction of the canvas movement, and the canvas is moved based on the canvas movement direction. The above scheme solves the problem that the current electronic canvas can only be moved manually and is prone to misoperation, thereby realizing the automatic movement of the canvas, and determining the reference direction of the canvas movement that can reflect the user's recording tendency, and moving the canvas based on the reference direction of the canvas movement. After the movement, the user's most recently recorded content can be retained and displayed, and more blank areas can be called out for operation through movement, and the direction of the drawing board movement takes into account the user's writing direction, and the called out blank area can meet the user's position requirements for continued recording, thereby improving the user experience.

[0058] Embodiment 2

[0059] Figure 6 This is a flowchart of a canvas moving method provided in the second embodiment of the present application. The present embodiment is optimized based on the above embodiment. For solutions not described in detail in the present embodiment, please refer to the above embodiment. Figure 6 As shown, the method of the embodiment of the present application specifically includes the following steps:

[0060] S210: Determine distribution data of the recorded content on the canvas, and determine whether the canvas meets the moving condition according to the distribution data.

[0061] S220: If the canvas meets the moving condition, determine the target block corresponding to the target timestamp, and determine the position of the target block on the canvas; wherein the target timestamp is a timestamp within a preset time from the current moment.

[0062] The preset time from the current moment may be a period of time closest to the current moment. The target block corresponding to the target timestamp within the period of time closest to the current moment may be searched in each block of the canvas, and the position of the target block on the canvas may be determined. The position of the target block on the canvas may be the area of ​​the target block in the canvas, or may be the relative position of different target blocks.

[0063] S230: Determine a reference direction for canvas movement according to the position of the target block on the canvas.

[0064] Exemplarily, since the target block is a timestamp within a preset time from the current moment, the target block can reflect the position where the user recently put down the pen, and the reference direction of the canvas movement can be determined accordingly. Specifically, assuming that the target block is located on the right side of the canvas, the reference direction of the canvas movement can be determined to be from left to right. If the position of the target block on the canvas is the relative position of the target block in the canvas, assuming that the target block corresponding to the timestamp closest to the current moment is on the right, and the target block corresponding to the timestamp before the timestamp is on the left, the reference direction of the canvas movement is determined to be from left to right.

[0065] For example, Figure 7 As shown, the canvas can be divided into an upper area and a lower area. If the target block corresponding to the most recent timestamp closest to the current moment, or a preset target block, is located in the upper area, the reference direction of the canvas movement is determined to be from bottom to top. If the target block corresponding to the most recent timestamp, or a preset target block, is located in the lower area, the reference direction of the canvas movement is determined to be from top to bottom, reflecting that the recorded content is recorded from the top of the canvas to the bottom of the canvas as a whole. Figure 8 As shown, the canvas can also be divided into a left area and a right area. If the target block corresponding to the latest timestamp or the preset target block is located in the left area, the reference direction of the canvas movement is determined to be from right to left, reflecting that the recorded content is recorded from the right side of the canvas to the left side of the canvas as a whole. If the target block corresponding to the latest timestamp or the preset target block is located in the right area, the reference direction of the canvas movement is determined to be from left to right. Fig. 9As shown, the canvas can also be divided into four areas: the upper left area, the lower left area, the upper right area, and the lower right area. If the target block corresponding to the most recent timestamp or the preset target block is located in the upper left area, the reference direction of the canvas movement is determined to be from the lower right to the upper left. If the target block corresponding to the most recent timestamp or the preset target block is located in the lower left area, the reference direction of the canvas movement is determined to be from the upper right to the lower left. If the target block corresponding to the most recent timestamp or the preset target block is located in the upper right area, the reference direction of the canvas movement is determined to be from the lower left to the upper right. If the target block corresponding to the most recent timestamp or the preset target block is located in the lower right area, the reference direction of the canvas movement is determined to be from the upper left to the lower right. The canvas can also be divided into other numbers of areas, and the reference direction of the canvas movement can be further determined according to the area where the target block is located.

[0066] In the embodiment of the present application, determining the reference direction of the canvas movement according to the position of the target block on the canvas includes:

[0067] Starting from the most recent timestamp, traverse the target timestamps in order from the nearest to the current moment until the target block corresponding to the target timestamp is located in the non-corner area of ​​the canvas; wherein the most recent timestamp is the target timestamp closest to the current moment; the non-corner area is the area of ​​the canvas excluding the corner area; the corner area is the area within the first preset range of the canvas vertex;

[0068] According to the position of the target block corresponding to the target timestamp in the canvas, a reference direction for the canvas movement is determined.

[0069] For example, Fig.10 As shown, Fig.10The entire area is the canvas, wherein the area within the first preset range of the four vertices is the corner area, and the four vertices correspond to the four corner areas. The first preset range can be determined according to actual conditions. The area other than the corner area in the canvas is the non-corner area. Since users generally tend to record in non-corner areas, the user's recording behavior in non-corner areas can be searched. In order to determine the canvas area where the user's most recent recording behavior is located, the target timestamps can be traversed in order from near to far from the current moment until the target block corresponding to the target timestamp is located in the non-corner area of ​​the canvas. Specifically, first traverse the most recent timestamp to determine whether the block corresponding to the most recent timestamp is located in the non-corner area. If so, stop traversing. If the block corresponding to the most recent timestamp is in the corner area, continue to traverse the previous target timestamp of the most recent timestamp to determine whether the block corresponding to the previous target timestamp is in the non-corner area. If so, stop traversing. If the block corresponding to the previous target timestamp is in the corner area, continue to traverse the previous target timestamp of the previous target timestamp, and so on, until the first traversed block corresponding to the target timestamp is in the non-corner area. In this case, the reference direction of the canvas movement is determined according to the position of the target block corresponding to the target timestamp in the canvas.

[0070] In the embodiment of the present application, determining the reference direction of the canvas movement according to the position of the target block corresponding to the target timestamp in the canvas includes:

[0071] If the target block corresponding to the most recent timestamp is located in a critical area in the non-corner area of ​​the canvas, the reference direction of the canvas movement is determined to be a direction from the center of the canvas to the center of the critical area; wherein the critical area is an area within a second preset range adjacent to the canvas boundary in the non-corner area;

[0072] If the target block corresponding to the most recent timestamp is located in the middle area of ​​the non-corner area of ​​the canvas, the reference direction of the canvas movement is determined to be from top to bottom, or, the reference direction of the canvas movement is determined based on the distribution of the target blocks corresponding to a preset number of consecutive target timestamps closest to the current moment in the canvas.

[0073] For example, Fig.11 As shown, the non-corner area can be divided into a critical area and an intermediate area. The critical area can be an area within a second preset range adjacent to the canvas boundary in the non-corner area. The second preset range can be determined according to actual conditions, such as Fig.11 As shown, the canvas has four boundaries, and the four critical areas within the second preset range adjacent to the four boundaries of the canvas and not adjacent to each other are area 1, area 2, area 3 and area 4. The area other than the critical area in the non-boundary area is the middle area.

[0074] If the target block corresponding to the most recent timestamp is located in the critical area of ​​the non-corner area of ​​the canvas, the reference direction of the canvas movement is determined to be the direction from the center of the canvas to the center of the critical area. Exemplarily, if the target block corresponding to the most recent timestamp is located in area one, the reference direction of the canvas movement is determined to be the direction from the center of the canvas to the center of area one, that is, from bottom to top. If the target block corresponding to the most recent timestamp is located in area two, the reference direction of the canvas movement is determined to be the direction from the center of the canvas to the center of area two, that is, from left to right. The same is true when the target block corresponding to the most recent timestamp is located in other critical areas.

[0075] If the target block corresponding to the most recent timestamp is located in the middle area of ​​the non-corner area of ​​the canvas, the reference direction of the canvas movement can be set to be from top to bottom based on the user's regular recording habit from top to bottom. The reference direction of the canvas movement can also be determined based on the distribution of the target blocks corresponding to the preset number of consecutive target timestamps closest to the current moment in the canvas. For example, search for the 5 consecutive target timestamps closest to the current moment. If the target blocks corresponding to the target timestamps from early to late are distributed from left to right, the reference direction of the canvas movement is determined to be from left to right. If the target blocks corresponding to the target timestamps from early to late are distributed from top to bottom, the reference direction of the canvas movement is determined to be from top to bottom.

[0076] The above scheme can accurately predict the user's writing direction or painting direction based on the user's last pen placement, and then determine the direction of canvas movement according to the user's operating habits to move the canvas, ensuring that after the canvas moves, more blank areas can be moved along the reference direction of the canvas movement for the user to continue recording according to the reference direction of the original canvas movement, thereby improving the user experience.

[0077] In the embodiment of the present application, determining the reference direction of the canvas movement according to the position of the target block corresponding to the target timestamp in the canvas includes:

[0078] If the target block corresponding to the most recent timestamp is located in the corner area of ​​the canvas, the center of the canvas area where the first traversed target block located in the non-corner area is located is pointed to the direction of the center of the corner area, which is determined as the reference direction of the canvas movement.

[0079] Exemplarily, in the process of traversing the target timestamps in order from near to far from the current moment, if the target block corresponding to the most recent timestamp is located in the corner area of ​​the canvas, the traversal continues until the first traversed target timestamp corresponding to the target block is located in the non-corner area, and the direction in which the center of the non-corner area points to the center of the corner area where the block corresponding to the most recent timestamp is located is determined as the reference direction for the canvas movement.

[0080] Specifically, Fig.11As shown, assuming that the target block corresponding to the most recent timestamp is located in area five, then during the traversal process, if the target block corresponding to the last target timestamp of the most recent timestamp is located in area four, the direction from the center of area four to the center of area five is determined as the reference direction for the movement of the canvas, that is, from bottom to top. If the target block corresponding to the last target timestamp of the most recent timestamp is located in the middle area, the direction from the center of the middle area to the center of area five is determined as the reference direction for the movement of the canvas, that is, from the lower right to the upper left. If the target block corresponding to the last target timestamp of the most recent timestamp is located in area six, and the target block corresponding to the last target timestamp of the last target timestamp is located in area four, the direction from the center of area four to the center of area five is determined as the reference direction for the movement of the canvas, that is, from bottom to top.

[0081] The above scheme takes into account that the user's main recording area is the non-corner area, and therefore searches to determine the most recent pen-place position in the non-corner area, and combines the user's last pen-place position to accurately predict the user's preferred recording direction, and determines the reference direction of the canvas movement accordingly, so that the canvas movement direction can be determined according to the reference direction of the canvas movement to meet the user's recording habits after the canvas is moved, thereby improving the user experience.

[0082] In the embodiment of the present application, determining the reference direction of the canvas movement according to the position of the target block on the canvas includes:

[0083] If the target blocks are all located in the same corner area, the direction from the center of the canvas to the corner area is used as the reference direction for canvas movement.

[0084] For example, if after traversing the target timestamps, the target blocks corresponding to all the target timestamps are located in the same corner area, that is, the user has recorded in the same corner area in the recent period of time, then the direction of the canvas center pointing to the corner area is used as the reference direction of the canvas movement.

[0086] The embodiment of the present application provides a canvas movement method, which determines the distribution data of the recorded content on the canvas, and determines whether the canvas meets the moving conditions based on the distribution data; if the canvas meets the moving conditions, the target block corresponding to the target timestamp is determined, and the position of the target block on the canvas is determined; wherein the target timestamp is a timestamp within a preset time from the current moment; according to the position of the target block on the canvas, the reference direction of the canvas movement is determined. The canvas movement direction is determined according to the reference direction of the canvas movement, and the canvas is moved based on the canvas movement direction. The above scheme can accurately predict the overall writing direction that the user tends to tend to when recording on the canvas according to the user's recording habits in the recent period of time, and then determine the reference direction of the canvas movement, so as to determine the canvas movement direction according to the reference direction of the canvas movement to move the canvas, and ensure that after the canvas moves, more blank areas can be moved out along the reference direction of the user's canvas movement for the user to continue recording in the original recording direction, thereby improving the user experience.

[0088] Fig.12 This is a flowchart of a canvas moving method provided in the third embodiment of the present application. The present embodiment is optimized based on the above embodiment. For solutions not described in detail in the present embodiment, please refer to the above embodiment. Fig.12 As shown, the method of the embodiment of the present application specifically includes the following steps:

[0089] S310: Determine distribution data of the recorded content on the canvas, and determine whether the canvas meets the moving condition based on the distribution data.

[0090] In an embodiment of the present application, determining distribution data of recorded content on a canvas, and determining whether the canvas meets a moving condition according to the distribution data, includes:

[0091] If the distribution data satisfies at least one of the following, the canvas is determined to meet the moving conditions:

[0092] The number of blocks of the marked data as preset data reaches a first preset number of blocks;

[0093] The target block corresponding to the most recent timestamp closest to the current moment is located in a non-corner area of ​​the canvas, and the number of blocks in the non-corner area marked with preset data reaches a second preset number of blocks;

[0094] The blocks corresponding to the consecutive preset number of timestamps closest to the current moment are located in the corner area of ​​the canvas, and the number of blocks in the corner area whose marked data is preset data reaches a third preset number of blocks.

[0095] Exemplarily, the distribution of blocks containing recorded content in the canvas can be determined based on the marking data. If the marking data of the block is preset data, it is determined that the block contains recorded content. The number of blocks whose marking data is preset data is counted to determine whether the number of blocks reaches a first preset number of blocks. If the number of blocks reaches the first preset number of blocks, it is determined that the recorded content almost fills the canvas. The first preset number of blocks can be determined based on actual conditions, for example, it can be set to 70% of the total number of blocks on the canvas.

[0096] If the target block corresponding to the most recent timestamp is located in a non-corner area of ​​the canvas, it is determined whether the number of blocks in the non-corner area whose marked data is preset data reaches the second preset number of blocks, thereby judging whether the recorded content in the non-corner area has almost covered the non-corner area. The second preset number of blocks can be determined according to actual conditions, for example, it can be set to 70% of the total number of blocks in the non-corner area. For example, if the target block corresponding to the most recent timestamp is located in area four, the number of blocks in area four whose marked data is preset data is counted to determine whether the number of blocks reaches 70% of the total number of blocks in area four.

[0097] If the blocks corresponding to the preset number of consecutive timestamps closest to the current moment are located in the corner area of ​​the canvas, it is determined whether the number of blocks in the corner area with marked data as preset data reaches a third preset number of blocks, which can be determined according to actual conditions, for example, can be set to 70% of the corner area. If the number of blocks reaches the third preset number of blocks, it is determined that the recorded content almost covers the corner area.

[0098] S320. If the canvas meets the moving condition, the reference direction of the canvas movement is determined according to the marking data of the blocks on the canvas and the corresponding timestamps; wherein the marking data is used to indicate whether there is recorded content on the blocks, and the timestamp is used to indicate the recording time of the recorded content.

[0099] S330: Performing a simulated canvas movement in the background of the canvas mobile device based on the opposite direction of the reference direction of the canvas movement to obtain a simulated canvas.

[0100] Exemplarily, in order to avoid the problem of having no blank area for user recording after directly moving the canvas, the canvas can be simulated moved in the opposite direction of the reference direction of the canvas movement in the background of the canvas mobile device before moving the canvas to obtain a simulated canvas.

[0101] S340: If the simulated canvas satisfies a preset condition, the opposite direction of the reference direction of the canvas movement is used as the canvas movement direction; wherein the preset condition is that the number of blocks in the simulated canvas whose marked data is preset data is less than a fourth preset number of blocks.

[0102] S350: If the simulated canvas does not meet the preset condition, continue to simulate the movement of the canvas in the opposite direction of the reference direction of the canvas movement, and determine the moving direction of the canvas according to the moving direction of the simulated canvas when the preset condition is met.

[0103] The preset condition can be determined according to actual conditions, for example, the number of blocks with preset data in the simulated canvas is less than the fourth preset number of blocks. The fourth preset number of blocks can be determined according to actual conditions, for example, 80% of the total number of blocks in the simulated canvas.

[0104] The preset condition may also be at least one of the following:

[0105] The number of blocks of the marked data as preset data is less than the first preset number of blocks;

[0106] The target block corresponding to the most recent timestamp closest to the current moment is located in a non-corner area of ​​the simulation canvas, and the number of blocks in the non-corner area marked with data as preset data is less than the second preset number of blocks;

[0107] The blocks corresponding to the preset number of consecutive timestamps closest to the current moment are located in the corner area of ​​the simulation canvas, and the number of blocks marked with preset data in the corner area is less than the third preset number of blocks.

[0108] For details, please refer to the description in S310.

[0109] If the simulated canvas does not meet the preset conditions, it is determined that the blank area in the simulated canvas still does not meet the user's recorded needs, so the simulated movement of the canvas continues in the opposite direction of the reference direction of the canvas movement to obtain a new simulated canvas, and the moving direction of the canvas is determined according to the moving direction of the simulated canvas when the preset conditions are met. For example, assuming that the new simulated canvas obtained after continuing to simulate the movement of the canvas in the opposite direction of the reference direction of the canvas movement meets the preset conditions, the opposite direction of the reference direction of the canvas movement is used as the canvas moving direction.

[0110] In the embodiment of the present application, the canvas is simulated and moved in the opposite direction of the reference direction of the canvas movement, and the moving direction of the canvas is determined according to the moving direction of the simulated canvas when the preset condition is satisfied, including:

[0111] Continue to simulate the movement of the canvas based on the opposite direction of the reference direction of the canvas movement until the simulated canvas meets the preset conditions, and use the opposite direction of the reference direction of the canvas movement as the canvas movement direction;

[0112] If the number of times the canvas is simulated moved in the opposite direction of the reference direction of the canvas movement reaches a preset number and the simulated canvas does not meet the preset conditions, the canvas is simulated moved based on an adjustment direction, and the adjustment direction when the simulated canvas meets the preset conditions is used as the canvas movement direction; wherein the adjustment direction is a direction other than the opposite direction of the reference direction of the canvas movement.

[0113] Exemplarily, if the simulated movement of the canvas continues to be performed in the opposite direction of the reference direction of the canvas movement, and the number of simulated movements of the canvas in the opposite direction of the reference direction of the canvas movement does not reach a preset number of times, and the simulated canvas meets the preset conditions, the opposite direction of the reference direction of the canvas movement is used as the canvas movement direction. At this time, the total amplitude of the simulated movement of the canvas can be determined according to the number of movements in the opposite direction of the reference direction of the canvas movement and the amplitude of each movement, so as to move the canvas according to the total amplitude and the opposite direction of the reference direction of the canvas movement. If the simulated movement of the canvas continues to be performed in the opposite direction of the reference direction of the canvas movement, and the number of simulated movements of the canvas in the opposite direction of the reference direction of the canvas movement reaches a preset number of times, it means that after multiple movements, the simulated canvas still has no more blank areas to meet the user's recording needs, then the simulated movement of the canvas is no longer performed in the opposite direction of the reference direction of the canvas movement, but the simulated movement of the canvas is performed based on the adjustment direction, and the adjustment direction when the simulated canvas meets the preset conditions is used as the canvas movement direction, and the adjustment direction is other directions different from the opposite direction of the reference direction of the canvas movement. For example, if the simulated movement of the canvas continues in the opposite direction of the reference direction of the canvas movement, and the number of simulated movements of the canvas in the opposite direction of the reference direction of the canvas movement reaches a preset number, the simulated movement of the canvas is performed again based on the reference direction of the canvas movement. If the simulated canvas meets the preset conditions, the reference direction of the canvas movement is used as the direction of the canvas movement. Alternatively, the direction perpendicular to the reference direction of the canvas movement can be used as the adjustment direction, and the simulated movement of the canvas is performed based on the adjustment direction. If the simulated canvas meets the preset conditions, the direction perpendicular to the reference direction of the canvas movement is used as the direction of the canvas movement. The above scheme can evaluate the simulated canvas after the simulated movement to determine whether the simulated canvas contains more blank areas for the user to record. If not, the movement continues to be attempted to move out more blank areas for the user to record in the simulated movement.

[0114] In the embodiment of the present application, if the simulated canvas still does not meet the preset conditions after multiple canvas simulation moves, a new blank canvas can be directly created for the user to write.

[0115] S360: Move the canvas based on the canvas moving direction.

[0116] The embodiment of the present application provides a canvas moving method, in which a simulated canvas movement is performed in the background of a canvas mobile device based on the opposite direction of a reference direction of the canvas movement to obtain a simulated canvas. If the simulated canvas meets a preset condition, the opposite direction of the reference direction of the canvas movement is used as the canvas moving direction. If the simulated canvas does not meet the preset condition, the simulated canvas movement is continued in the opposite direction of the reference direction of the canvas movement, and the canvas moving direction is determined according to the moving direction of the simulated canvas when the preset condition is met. The above scheme avoids the problem that there is still no blank area for the user to record after the canvas is directly moved. By performing a simulated movement of the canvas, a blank area for the user to record is first tried to be moved, and then the final canvas moving direction is determined according to the direction of the simulated movement, so as to ensure that more blank areas can be moved out for the user to record and write after the canvas is moved based on the canvas moving direction, thereby improving the user experience.

[0117] Embodiment 4

[0118] Fig.13 This is a flowchart of a canvas moving method provided in the fourth embodiment of the present application. The present embodiment is optimized based on the above embodiment. For solutions not described in detail in the present embodiment, please refer to the above embodiment. Fig.13 As shown, the method of the embodiment of the present application specifically includes the following steps:

[0119] S410: Determine distribution data of the recorded content on the canvas, and determine whether the canvas meets the moving condition according to the distribution data.

[0120] S420. If the canvas meets the moving condition, the reference direction of the canvas movement is determined according to the marking data of the blocks on the canvas and the corresponding timestamps; wherein the marking data is used to indicate whether there is recorded content on the blocks, and the timestamp is used to indicate the recording time of the recorded content.

[0121] S430: Determine a canvas movement direction according to a reference direction of the canvas movement, and move the canvas based on the canvas movement direction.

[0122] S440: Delete the marking data of the removed block and the corresponding timestamp that are moved out of the canvas, and store the corresponding removal record content in the removed block.

[0123] For example, if the recorded content of some blocks is moved out of the canvas after the canvas is moved, the marking data and the corresponding timestamp of the removed blocks where the recorded content is removed from the canvas are deleted. In the subsequent canvas application process, it may be necessary to move the recorded content that has been moved out of the canvas back into the canvas, so the removed recorded content in the removed blocks needs to be stored so that it can continue to be displayed in the canvas when it is moved back later.

[0124] S450: If the removed recorded content is moved back into the canvas, the marking data of the new block where the removed recorded content is located is updated, and the timestamp corresponding to the new block is determined according to the time when the removed recorded content is moved back.

[0125] Exemplarily, if the removed recorded content is moved back into the canvas, the new block where the removed recorded content is located after being moved back into the canvas is located is located, the marking data of the new block is updated to the preset data, and the time when the removed recorded content is moved back to the new block is used as the timestamp corresponding to the new block, and the marking data and timestamp of the new block are updated.

[0126] The embodiment of the present application provides a canvas moving method, which determines the canvas moving direction according to the reference direction of the canvas movement, and after the canvas is moved based on the canvas moving direction, deletes the mark data and corresponding timestamp of the removed block that is moved outside the canvas, and stores the corresponding removed record content in the removed block. If the removed record content is moved back into the canvas, the mark data of the new block where the removed record content is located is updated, and the timestamp corresponding to the new block is determined according to the time when the removed record content is moved back. The above scheme stores the recorded content that has been moved out, deletes the mark data and timestamp of the block corresponding to the recorded content, so as to facilitate the subsequent display of the recorded content when the recorded content is moved back into the canvas, and updates the mark data and corresponding timestamp of the new block of the recorded content, thereby realizing the two-way movement of the canvas, avoiding the disappearance of the previous recorded content after the canvas is moved, and improving the user experience.
