In this embodiment, through the above steps, the handwriting reader completes adaptive switching of the pen tip style icon. Judging whether the layer of the next page contains a handwritten layer or not, and judging that the page has high possibility of writing when the switched page contains the handwritten layer, so that the stroke style icon is kept; when the switched page does not contain the handwritten layer, for example, when the page is switched to a directory page or a setting page, it is determined that writing on the page is less likely, and therefore, the stroke style icon is switched back to the global menu icon, which is convenient for performing other operations using the global menu.
Further, after the step S204, if the page switching command is received again, the following steps are executed:
in step S205, when the page switching instruction is received again, the next page is read from the cache.
Specifically, when step S204 is completed and the stroke style icon is switched back to the global menu icon, and page switching is performed again, the handwriting reader reads the next page stored in advance from the system cache after receiving a page switching instruction.
Step S206, detecting the view structure of the next page, judging whether the layer of the next page contains a handwritten layer or not, if so, executing step S207; if not, go to step S208.
Specifically, the handwriting reader detects a view structure of a next page, acquires layer information of the next page, and judges whether a handwriting layer exists in the next page from the acquired layer information.
Step S207, page switching is carried out, and the global menu icon is switched to the pen style icon again.
Specifically, after step S206, after determining whether a next page has a handwritten layer, if the determination result is that the layer of the next page includes the handwritten layer, the page is switched, the handwriting reader displays the next page, and the global menu icon is switched to the tip style icon again, that is, the tip style icon is displayed in the next page.
And step S208, switching pages and keeping the global menu icons unchanged.
Specifically, after step S206, after determining whether a next page has a handwritten layer, if the determination result is that the layer of the next page does not include the handwritten layer, the page is switched, and the handwriting reader displays the next page and keeps the global menu icon unchanged, that is, displays the global menu icon in the next page.
In this embodiment, through the above steps, the handwriting reader completes adaptive switching of the global menu icon. Judging whether the layer of the next page contains a handwritten layer, and switching the global menu icon back to the stroke style icon when the switched page contains the handwritten layer; and when the switched page does not contain the handwritten layer, keeping the global menu icon. That is, in this embodiment, by detecting the next page view structure, the global menu icon or the stroke style icon is adaptively switched according to whether the next page view structure includes a handwritten layer, so that the operation of the user is more convenient.
In a further embodiment of the present invention, on the basis of the embodiment of the method shown in fig. 1, after step S101, a process of determining the position of the pen-tip style icon is further included. Fig. 3 is a schematic diagram illustrating a process of determining a location of a pen tip style icon according to an embodiment of the present invention, and as shown in fig. 3, the method includes the following steps:
step S301, reading the coordinate data of the pen point in real time.
Specifically, after the global menu icon is switched to the tip style icon, coordinate data corresponding to the contact position of the pen point of the handwriting pen is acquired through the screen of the handwriting reader.
Preferably, through an electromagnetic film at the bottom of the screen of the handwriting reader, the writing parameters of the pen point of the handwriting pen, including coordinates, pressure and the like, are detected by utilizing electromagnetic response; and the handwriting reader reads the coordinate parameters of the pen point in real time.
Step S302, updating the presenting coordinate data of the tip style icon according to the coordinate data of the pen point.
Specifically, the presenting coordinate data of the updated rear pen point style icon is determined according to the coordinate data of the pen point; wherein a distance between the coordinates of the pen tip and the coordinates of the tip style icon is within a preset distance range. And displaying the pen-tip style icon at a corresponding position of a screen according to the updated presentation coordinate data of the pen-tip style icon.
Preferably, the distance between the coordinate of the pen point and the coordinate of the pen point style icon is smaller than a preset distance, the distance between the pen point style icon and the writing position can be kept within a certain range, and it is guaranteed that the moving distance of the pen point does not need to be too large when a user needs to click and search the pen point style icon to switch the pen point. In addition, the display position of the stroke style icon is refreshed while the screen refreshes the writing stroke point, and the screen refreshes the position change of the stroke style icon independently.
Further, step 302 may further include:
detecting a distance difference value between coordinate data of adjacent pen points;
and if the distance difference is larger than a preset threshold value, updating the presenting coordinate data of the tip style icon according to the coordinate data of the pen point.
Specifically, coordinate data of adjacent pen points in the writing process are obtained through a screen of the handwriting reader, and a distance difference value between the coordinate data of the adjacent pen points in front and back is determined; and judging the distance difference, if the distance difference is larger than a preset threshold, updating the presenting coordinate data of the pen point style icon according to the coordinate data of the pen point, and displaying the pen point style icon at a corresponding position of a screen according to the updated presenting coordinate data of the pen point style icon. According to the embodiment, the distance between the coordinates of the pen point and the coordinates of the pen point style icon is within a preset distance range, so that the pen point style icon is not too far away from the position of the pen point, the situation that the distance between the pen point style icon and the pen point is too far away is prevented, and the user can perform pen point style switching operation only when the finger or the pen point of the user needs to move too far; meanwhile, the moving distance of the pen point is determined by detecting the distance difference between the coordinate data of the adjacent pen points before and after the pen point is detected, and the position of the pen point style icon is adjusted only when the moving distance of the pen point exceeds a preset threshold; the pen point type icon can not move continuously along with the pen point in a small range when the pen point moving distance is small, the movement of the pen point type icon under the condition can not greatly influence the improvement of the use convenience of a user, but can interfere the writing of the user, and the embodiment can effectively avoid the situation.
In the above embodiment, the position of the tip style icon is determined based on the position of the pen tip, and when the pen tip moves, the tip style icon also moves in a corresponding manner.
FIG. 4 is a schematic diagram of a handwriting reader interface according to another embodiment of the invention, as shown in FIG. 4, showing the position of the pen tip captured by the handwriting reader screen during writing and the palm contact area where the palm of the user's pen is in contact with the screen (see the area outlined by the dashed line in FIG. 4).
Specifically, the embodiment can acquire the position data of the palm touch area by using the capacitive screen; updating the presenting coordinate data of the pen point style icon according to the position data of the palm touch area; and the presenting coordinate of the pen point style icon is positioned in the palm touch area.
Preferably, in the case shown in fig. 4, a contact area between a palm of a user and a screen is detected through a capacitive screen of the handwriting reader, and position data of a palm touch area is acquired; and enabling the presenting coordinates of the stroke style icon to be located in the palm touch area, namely displaying the stroke style icon in the palm touch area. According to the embodiment, the pen point style icon does not generate extra shielding on the screen display content, and the palm touch area is not changed when writing in a small range, so that the pen point style icon does not need to be frequently changed in position, and a user can click the pen point style icon to switch pen points by lifting hands.
Different from fig. 4, the present invention further provides another determination method for the position of the stroke style icon, and fig. 5 shows a schematic diagram of page content and screen contact position in the process of determining the position of the stroke style icon according to another embodiment of the present invention, as shown in fig. 5:
fig. 5 includes that, in the writing process, the pen point position acquired by the screen of the handwriting reader and the palm contact position where the palm of the user holding the pen is in contact with the screen are determined by the center point of the palm contact position and the extension line of the connection line of the pen point position.
Specifically, the embodiment can read the coordinate data of the pen point in real time; acquiring position data of a palm touch area by using a capacitive screen; acquiring a connecting line between the coordinates of the center point of the palm touch area and the coordinates of the pen point, and using the coordinate direction towards the pen point as an extension line of the connecting line; and updating the presenting coordinate data of the pen point style icon according to the extension line, wherein the presenting coordinate of the pen point style icon is on the extension line.
Preferably, in the case shown in fig. 5, a contact area between a palm of a user and a screen and a position of a pen point of a handwriting pen are detected through a capacitive screen of the handwriting reader, and position data of the palm touch area and coordinate data of the pen point are acquired; and determining the pen point style icon on an extension line of a connecting line between the coordinate of the center point of the palm touch area and the coordinate of the pen point towards one side of the pen point position, namely, the pen point style icon is positioned on the extension line. Meanwhile, the minimum distance between the stroke style icon coordinate data and the pen point position coordinate data is preset, and the distance between the stroke style icon position and the pen point position must be larger than the minimum distance. According to the embodiment, a user can touch the pen point style icon by changing the pen holding angle, and the pen point style icon is not too close to a writing area in the writing process, so that the writing content is shielded.
