Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present specification more apparent, the present specification will be further described in detail below with reference to the accompanying drawings.

The terms "first," "second," and the like, as used in embodiments of the present application, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements, articles, or method steps preceding the word are included in the listed elements, articles, or method steps following the word, and equivalents thereof, without precluding other elements, articles, or method steps. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
As described in the background art, in a specific application scenario such as education, if a teacher opens a writing mode such as an annotation mode that can optionally write on an intelligent device such as a large screen when the teacher lectures on the large screen, when the user turns over a page in a sliding manner, the interface receives a corresponding touch event message (e.g., a touch down message, a touch slide message, a touch up message, etc.) due to the opening of the annotation mode, so handwriting can be drawn in real time. After the sliding is completed, whether the sliding is a page turning operation or not is judged according to the specific information of the sliding. If the page turning operation is performed, so that redundant sliding handwriting is left on the previous page. The viewing experience of the student is greatly discounted and normal writing may be affected by the useless sliding notes left behind.
In combination with the above practical situation, the embodiment of the application provides a page turning handwriting processing scheme, by simultaneously generating a writing track and confirming a page turning gesture on a writing page, confirming whether the current touch operation is the page turning gesture according to sliding track information, executing the page turning operation after confirming, deleting the originally generated sliding track and the like, thereby avoiding the leaving of the page turning track and improving the watching experience of a user.
Fig. 1 is a schematic flow chart of a page turning handwriting processing method, which specifically includes:
step 101, obtaining sliding track information on a writing page.
In this step, touch information on the writing page is acquired, and the sliding track information is resolved according to the continuous movement of the touch point. In a specific application scene, a writing page is a page of a specific touch intelligent device, which can be subjected to touch handwriting input. The touch intelligent device can be a more convenient mobile intelligent device: cell-phone, tablet etc. also can be comparatively large-scale smart machine: intelligent touch televisions, intelligent touch large screens, intelligent touch whiteboards, and the like. The touch information is information generated by performing touch operation on the touch large screen by using a user finger or other components capable of simulating human fingers. For example, the touch information may include touch point selection information (touch point position, touch point area, etc.), touch slide information (start position, end position, start time, end time, position information of a point in the slide process, time information of a slide to the point, etc.), and the like. Furthermore, the sliding track information is touch data related to sliding, for example: start-stop position, start-stop time, number of touch points sliding, etc.
In some application scenarios, the writing mode on the writing page can be in various forms, such as single-finger writing and multi-finger writing, and the page turning handwriting processing scheme of the scheme can be performed in different writing modes. In other application scenarios, in the equipment with single-finger writing and multi-finger writing, in order to facilitate distinction, the scheme can be set to only aim at one writing mode, for example, only the single-finger writing mode is processed, if the multi-finger writing mode is set, the page turning operation is not executed no matter whether the page turning condition is met or not during sliding, and only the normal multi-finger writing operation is executed; or only processing the multi-finger writing mode, if the single-finger writing mode is set, the page turning operation is not executed no matter whether the page turning condition is met or not during sliding, and only normal single-finger writing operation is executed.
And 102, generating a sliding track on the writing page according to the sliding track information.
In this step, a slide trajectory is generated for display on the writing page. In the embodiment of the application, handwriting on the writing page is displayed in real time, so that a user is prevented from missing writing notes under the normal writing condition.
In some embodiments, a user performs a touch operation on a touch device, and each touch operation must take a specific time to be completed. Taking sliding as an example, in the sliding process of the user, since the whole track is not completed, whether the track belongs to the page turning gesture is not determined at this time, if the handwriting is not displayed in real time, if the sliding track information is confirmed to belong to the information corresponding to the normal writing operation in the subsequent judging process, the problems of track omission or delayed display and the like may be caused.
Further, with respect to the sliding track information that is occurring, since whether or not the sliding track information is the page-turning gesture information has not been finally confirmed, it is necessary to display the sliding track information on the current writing page, that is, to generate the sliding track, so as not to affect the acquisition and display of the writing track in the writing mode.
In a specific teaching application scene, when a teacher speaks a class, when entering a writing mode or an annotating mode, a manual sliding page turning is performed at the moment, and as the writing mode is opened, a sliding track cannot be distinguished from handwriting left by normal writing, the sliding track left by sliding page turning can be drawn in real time, and writing handwriting is left on a large screen. While manually sliding, judging whether the operation meets the page turning requirement or not in the following steps, and if so, executing the page turning operation.
Step 103, judging whether the sliding track information belongs to the page turning gesture information.
In the step, whether the current gesture is the page turning gesture information is determined according to the sliding track information, and the current gesture can be accurately identified, quickly identified and accurately distinguished by utilizing various conditions.
In some embodiments, when a general user wants to turn pages, whether the user writes with one or more fingers on the touch writing page, the speed of touch sliding is very fast, and the user must have a direction of page turning tendency, so that whether the current sliding track information is the page turning gesture information can be determined by the sliding speed and the sliding angle.
The sliding speed is the speed of the touch point during sliding, and the overall average speed can be calculated through the overall length and the overall time consumption of the whole section of sliding track, or the dynamic speed can be calculated in real time during sliding according to the lengths of two opposite points on the sliding track and the moving time consumption, i.e. the sliding speed can be the overall average speed or the real-time speed.
The sliding angle is the direction angle when the touch point slides. For the sliding angle, if the page turning is necessarily a page turning in a certain direction from the middle to the edge of a certain direction within a certain angle, the page turning is considered to be a page turning in the certain direction, so that the sliding angle needs to be confirmed within a certain range, for example, a range of 0 to 45 degrees and 315 to 360 degrees is a page turning to the left and a range of 135 to 225 degrees is a page turning operation within a circle with the touch down coordinate as the origin right horizontal line being zero, and the page turning is not considered to be a page turning operation when the sliding angle deviates from the range. Of course, the sliding angle may be the overall direction angle, or may be the real-time direction angle, or the like.
In a specific embodiment, the sliding track information includes touch down information and touch up information; the touch press information comprises touch press coordinates and touch press time; the touch-up information includes touch-up coordinates and touch-up time. The touch pressing coordinate is a contact coordinate point when the finger contacts the screen, and the touch lifting coordinate is a touch point of the finger on the screen before the finger is lifted off the screen after writing on the writing page by one pen. It should be understood that for single-finger writing, one writing track corresponds to a set of touch down information, i.e., one track corresponds to one touch down coordinate, one touch down time, one touch up coordinate, and one touch up time. For multi-finger writing, a plurality of writing tracks are corresponding at the same time, and each writing track corresponds to a touch pressing coordinate and a touch lifting coordinate. In the page turning application scene, if the plurality of writing tracks are tracks corresponding to the page turning gesture, touch pressing time and touch lifting time corresponding to the plurality of writing tracks are the same.
When the sliding speed is calculated, calculating the sliding length according to the touch down coordinate and the touch up coordinate; calculating the sliding time according to the touch pressing time and the touch lifting time; and determining the sliding speed according to the ratio of the sliding length to the sliding duration. For multi-finger sliding, the sliding speeds of the fingers are not greatly different when the page is turned, so that the sliding speed is determined by selecting the sliding track information corresponding to any finger.
When calculating the sliding angle, the sliding angle is determined according to the touch down coordinate and the touch up coordinate. The sliding angle is determined assuming touch down coordinates (x 0, y 0) and touch up coordinates (x 1, y 1) at the end of sliding. Specifically, it is assumed that both the touch down coordinate and the touch up coordinateFor the coordinate values obtained in the rectangular planar coordinate system, the sliding angle is the angle between the sliding track and the X-axis, and the sliding angle value isIf the sliding angle is the angle between the sliding track and the Y-axis, the sliding angle value is +.>For multi-finger sliding, the sliding track of each finger is parallel when the page is turned, so that the sliding angle is determined by selecting the sliding track information corresponding to any finger.
If the sliding speed is not less than the preset speed threshold, further determining whether the sliding angle is within a preset range, and if the sliding angle is within the preset range, determining that the sliding track information belongs to the page turning gesture information. If the sliding speed is smaller than the preset speed threshold, whether the sliding angle is within the preset range or not is not needed to be further determined, and the sliding track information is directly determined not to belong to the page turning gesture information. In other embodiments, it may be determined whether the sliding angle is within a preset range, and if so, it is further determined whether the sliding speed is not less than a preset speed threshold. The embodiment of the present application is not limited to the order of determination of the sliding speed and the sliding angle.
When the sliding track information meets the condition of the page-turning gesture information, the current sliding track information can be considered as the page-turning gesture information; if the condition is not satisfied, the current sliding track information is considered to be not page turning gesture information, the page turning cannot occur on the current page, and the sliding track information is more probable to be normal writing track information on the current page, so that the current sliding track is taken as the writing track.
And 104, executing page turning operation on the writing page in response to the sliding track information belonging to the page turning gesture information, and deleting the sliding track information.
In this step, after determining that the current touch information is the page turning gesture information, a page turning operation is performed, and a deletion process is performed on the touch track generated by the touch information, so that the touch track cannot be affected by the normally written touch track.
In some embodiments, when the sliding is finished, it is immediately determined whether the sliding is a page turning operation according to step 103, and a determination result is given. The judgment result is divided into two cases: first kind: if the page turning action is performed, the sliding track of the sliding track information is handwriting data generated by mistake during page turning. Second kind: if the page turning action is not performed, the information representing the sliding track is normal writing information on the writing page, and the sliding track is writing handwriting. And deleting the sliding track corresponding to the page turning operation.
From the above, it can be seen that, in the embodiment of the present application, by simultaneously performing the generation of the writing track and the confirmation of the page turning gesture on the writing page, whether the current touch operation is the page turning gesture is confirmed according to the sliding track information, after confirmation, the page turning operation is performed, and the operations such as deleting the originally generated sliding track are performed, thereby avoiding the leaving of the page turning track, and improving the viewing experience of the user.
It should be noted that, the method of the embodiments of the present application may be performed by a single device, for example, a computer or a server. The method of the embodiment of the application can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the methods of embodiments of the present application, and the devices may interact with each other to complete the methods.
It should be noted that the foregoing describes specific embodiments of the present application. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments described above and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
In other embodiments, before calculating the swipe length from the touch down coordinates and the touch up coordinates, it is first determined whether the writing pattern on the writing page is a single-finger writing pattern. If the writing mode of the current writing page is single-finger writing, other judging elements can be added to further confirm on the basis of the previous embodiment, for example: the number of touch points, the distance between touch points, etc.
Taking two conditions of the number of the touch points and the distance between the touch points as an example, responding to a single-finger writing mode, and judging whether the number of the touch points is larger than one according to touch pressing information; judging whether the distance between the touch points of two adjacent touch points is within a preset distance range or not in response to the number of the touch points being greater than one; and in response to the distance between the touch points being within the preset distance range, continuing to execute the calculation of the sliding length according to the touch down coordinate and the touch up coordinate. Therefore, whether the sliding track information belongs to the page turning gesture information is accurately judged in the single-finger writing mode.
The number of touch points is the number of points that a user contacts with the touch screen when performing touch operation on the touch screen, for example, the user slides on the touch screen by using two fingers, and then the number of touch points is two. The touch point distance is the determined relative distance between adjacent touch points. In a specific application scenario, because the current single-finger writing mode is adopted, when the number of touch points is more than one, it can be determined that the user wants to perform page turning operation. When the user wants to perform multi-finger page turning operation, the user usually gathers and slides several fingers of the touch control, so that when the number of touch control points is more than one, whether the distance between every two adjacent touch control points is smaller than a certain threshold value can be determined, and if the distance is smaller than the certain threshold value, the user is considered to be in multi-finger gathering and sliding, and is considered to want to perform page turning operation.
In this embodiment, since the handwriting mode of the existing smart device may have a multi-finger input mode, in which each finger input is part of the current writing, it is difficult to distinguish whether the current multi-finger gesture is writing or turning pages at all. Therefore, the scheme can be executed only in the single-finger writing mode, and in the multi-finger writing mode, the page turning operation is not executed no matter whether the page turning condition is met or not in the sliding process, and the normal multi-finger writing operation is executed. And when in the single-finger writing mode, the number of touch points and the distance between the touch points can be added on the basis of the previous embodiment to judge the page turning gesture information.
In a specific application scenario, for the number of touch points, in a normal writing mode, a user generally performs single-finger operation, otherwise, overlapping handwriting is generated. Therefore, when the user writes normally, there is typically only one corresponding touch point. Therefore, if at least two touch points are detected (i.e., the number of fingers is 2 or more for page turning), for example, a range of the number of touch points designated for page turning may be set to 2 to 4, then it is considered that a sliding page turning operation may occur. Then, for the distance between the touch points, namely the distance between the adjacent fingers operated by the user, only if the distance between all the touch points is within a certain range, the sliding page turning operation is considered to be possible, and if two sliding tracks with overlarge distances appear on the screen, the page turning operation is not considered to be normal.
In some embodiments, the determination of the single-finger writing swipe page-turning gesture may be based on only two conditions, i.e., the number of touch points and the distance between touch points. The swipe page-flip gesture may also be determined in combination with the swipe speed and swipe angle in the previous embodiment. And when all the four conditions are judged to be in accordance with the conditions, the current sliding track information is considered to be page turning gesture information. Of course, the order of the judgment conditions can be freely adjusted, i.e., can be performed in an order different from that in the above-described embodiment and still achieve the desired result.
In some embodiments, after confirming that the sliding track information belongs to the page-turning gesture information, the page-turning direction may also be determined by the sliding angle. That is, the sliding angle can also determine whether to turn up or down. For example: in the circumference of zero degree of the right horizontal line with the touch press coordinates as the origin, the range of 0 degree to 45 degrees and 315 degrees to 360 degrees is page-turning to the left (page-turning forward), the range of 135 degrees to 225 degrees is page-turning to the right (page-turning backward), and so on. The correspondence between the specific sliding direction and the page turning direction may be customized, which is not limited in this embodiment.
In other embodiments, after the sliding track information on the writing page is obtained, the sliding track corresponding to the page turning operation is not deleted immediately through the judgment in the above embodiments, so that the execution of the deletion operation does not affect the response speed of display and writing. That is, the priority of processing the page turning handwriting is low, and the processor is idle to execute the processing of the page turning handwriting. And adding a first mark to the obtained sliding track information no matter whether the obtained sliding track belongs to the sliding track corresponding to the page turning operation or not. And if the sliding track information does not belong to the page-turning gesture information, changing the first mark into the second mark. And displaying the sliding track corresponding to the sliding track information marked as the second mark when the writing page is displayed again. Thus, the sliding track information and the sliding track of each time are conveniently processed.
The first mark and the second mark may be different number marks or different letter marks, and the specific types of the first mark and the second mark are not limited in the embodiment of the present application. For example, the first flag is 0 and the second flag is 1. When the writing page is displayed again (for example, when the user turns the page back again), the sliding track information marked as 1 is directly identified as normal note data, and the corresponding sliding tracks are directly displayed in normal tracks.
In contrast, when it is determined that the current sliding track information belongs to the page turning gesture information, the state mark of the sliding track information is modified from the first mark to the third mark. The third mark, the first mark and the second mark are different marks. For example, if the third mark is 2, the deleting operation is directly performed on the sliding track information marked as 2, or when the current page is displayed again, the operation of not drawing or not displaying the sliding track corresponding to the sliding track information marked as 2 is performed. In a specific application scene, aiming at handwriting generated by sliding page turning error, if no meaning is given to business, the sliding track information with the mark state of 2 is deleted when the page is turned. If the data information needs to be reserved, the sliding track information with the mark state of 2 is not deleted, and only the track corresponding to the information is not drawn or hidden when the drawing is refreshed.
It should be understood that, as to whether the sliding track corresponding to the third mark needs to be reserved, the setting may be performed in advance for the presentation file. For example, a reservation mark is added in the stage of editing the display file, the sliding track information corresponding to the file marked with the reservation mark is reserved, and the sliding track information corresponding to the file not marked with the reservation mark is deleted. According to the embodiment of the application, the sliding track information during page turning can be reserved, so that the stay time of a user on each page of the display page can be determined according to the sliding track information, and the content of interest of the user is determined.
