Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

In order to solve the problems in the prior art, the invention provides a method and a device for determining a text editing position of touch equipment, wherein the text editing position is determined by moving a text area to be edited in a positioning area generated in a screen area of the touch equipment, so that the problems that the head line, the tail line, the top line, the tail line and the like cannot be positioned are solved; the text area can be edited by moving the text area relative to the screen area, and the text area does not need to be limited to be beyond the screen area, so that the application range is wider, and the practicability is higher; meanwhile, the positioning area realizes the twisting processing such as text amplification by performing the sphericization processing on the text, so that the characters at the position to be positioned are in the most prominent amplification state, the recognition rate is improved, meanwhile, the characters in adjacent rows cannot be shielded, the fuzzy recognition of the characters cannot be influenced, the context is more coherent, and the user experience is better.

Fig. 1 is a schematic diagram of main steps of a method for determining a text editing position of a touch device according to an embodiment of the present invention. As shown in fig. 1, the method for determining a text editing position of a touch device according to an embodiment of the present invention mainly includes the following steps S101 and S102.

Step S101: generating a positioning area according to a text editing positioning instruction, wherein the text editing positioning instruction is used for determining the position of text editing, and the positioning area is positioned in a screen area of the touch equipment;

step S102: and moving the text area to be edited in the positioning area to determine the text editing position, wherein a positioning cursor is arranged in the positioning area.

According to the technical scheme of the invention, when a user wants to edit the text, the position of the text editing needs to be positioned firstly. At this time, the system of the touch device may analyze the text editing positioning instruction according to the operation of the user (for example, the user presses the screen and drags the cursor position, or presses a finger to slide on the screen to drag the positioning cursor position), and then process the text editing positioning instruction, that is, generate a positioning area according to the text editing positioning instruction, where the positioning area is located in the screen area of the touch device. In particular, a positioning region may be added on the upper layer of the text region. The positioning area is used for performing enlargement processing on the text, so that determination of the text editing position can be performed more accurately. The size of the positioning area can be flexibly set according to the requirement, and generally, the width of the positioning area is preferably not more than half of the screen area. As can be understood by those skilled in the art, if the positioning area is too large, most of the whole screen area is the positioning area, which may affect the visual experience; if the positioning area is too small, it is not enough to display 5 characters in front and at the back, and the positioning result cannot be accurate.

In one embodiment of the invention, in order to enable the user to see the text content of the adjacent rows or adjacent columns when the text is enlarged, the user can better judge the text editing position from the whole content, and therefore, the positioning area is used for enlarging the text by performing the spherical processing on the text. Preferably, the positioning area may be circular or elliptical in shape, so that the spheronization process can be more conveniently performed. The sphericizing process refers to the process of shifting, extending and deforming the image or text in a region, and achieves the effect similar to that of using a spherical lens for viewing. Spherical lens means that the inner and outer surfaces of the lens are spherical surfaces, or one surface is spherical surface and the other half is plane surface. After the globalization process, the image or text in the area has various effects such as enlargement, reduction or distortion. Some image processing software commonly used at present can realize spherical processing, such as image processing software Adobe Photoshop (abbreviated as "PS") developed and released by Adobe Systems.

In consideration of the difficulty in text recognition, when the text is subjected to the sphericizing processing, the enlargement effect on the text can be set by setting a sphericizing value (for adjusting different degrees of distortion of sphericizing). In a preferred embodiment of the invention, the text is magnified by the fisheye lens by setting the sphericized numerical value so that the positioning area has the fisheye lens effect. The fisheye lens effect refers to an effect when an image or a character in an area is seen through the fisheye lens, and the fisheye lens belongs to a special lens in an ultra-wide-angle lens, and the visual angle of the fisheye lens is required to reach or exceed the range which can be seen by human eyes. In order to maximize the angle of view of the lens, the front lens of the lens is short in diameter and is parabolic and convex toward the front of the lens, much like the fish eye, so called "fish-eye lens".

In the technical scheme of the invention, after the positioning area is generated, when the user moves the text area, the positioning area does not disappear automatically, but stays at the original position until the user needs to regenerate the positioning area at other positions or the text editing of the user is finished.

According to an embodiment of the present invention, when the text region to be edited is moved within the positioning region in step S102, specifically, the text region to be edited may be moved within the positioning region by moving the text region to be edited within and/or outside the positioning region. In the embodiment of the present invention, regardless of the positional relationship (whether intersecting, containing, etc.) between the text region and the positioning region, when the user moves the text region to be edited, the text region may be moved at any position within the screen region (including within the positioning region and outside the positioning region), so that the text region moves within the positioning region, and the position of the text editing is determined by the positioning cursor provided within the positioning region.

According to still another embodiment of the present invention, a speed of moving the text region to be edited within the positioning region does not exceed a speed of moving the text region to be edited outside the positioning region. When the user moves the text area in the positioning area, the description is that the position where the positioning cursor stays (namely the text editing position) is required to be accurately judged, namely the position is finely adjusted, so the moving speed is slower; when the text area is moved outside the positioning area, the description does not determine which text editing, i.e. coarse position adjustment, is to be performed on a specific segment or line, so that the moving speed is faster. In practical application, the two speeds can be flexibly set to required values according to requirements, can be equal or unequal, and can be used for distinguishing coarse adjustment and fine adjustment or not.

According to an embodiment of the present invention, when distinguishing between coarse tuning and fine tuning, if the positioning region is located outside the text region to be edited, the text region to be edited is moved at least partially into the positioning region by moving the text region to be edited outside the positioning region, and then the text region to be edited is moved again within the positioning region to accurately determine the text editing position.

In addition, when the text area to be edited moves in the positioning area, the position for text editing can be determined by setting the positioning cursor in the positioning area. In the prior art, a mature algorithm exists, for example, taking a windows system as an example, and cursor positioning can be achieved by calling a setConsole CursorPosition function for positioning a cursor position in an API (Application Programming Interface). That is to say, as long as the text area to be edited moves in the positioning area, the function can automatically judge the specific position where the cursor stays, and the text editing position is determined.

According to the implementation process of the embodiment of the present invention described above, it can be seen that the following strategies are adopted in determining the text editing position (positioning cursor) in one specific embodiment of the present invention:

1. the generated positioning area has an unchanged position relative to the screen area;

2. moving the text region to be edited at all positions of the screen region, including inside the positioning region and outside the positioning region, so that the relative position of the text region to the screen region or the positioning region is changed, but moving the text region to be edited inside the positioning region does not exceed moving the text region to be edited outside the positioning region;

3. any position of the text area can be moved into the positioning area, and the head line, the tail line, the top line and the tail line can be accurately positioned.

The following describes a specific implementation process of the technical scheme of the invention with reference to specific embodiments.

Fig. 2 is a schematic diagram of the positional relationship of the respective regions according to an embodiment of the present invention. As shown in fig. 2, the positional relationship of the screen region a, the text region B, and the positioning region D is shown, wherein the positioning region D is located at the midpoint of the screen region a. In addition, since the positioning region D is exemplified by the fact that the fish-eye lens effect can be achieved in the embodiment, and the projection of the positioning region D is a perfect circle, in the implementation of the program, a circumscribed square region C of the positioning region D can also be set for determining the position of the positioning region D.

In fig. 2, the screen area a is an area visible to the user, and the upper left corner position thereof is defined as (A.x, A.y); the text area B is a text area to be edited, the text area can be moved by operations such as dragging by a user, the position of the upper left corner of the text area is defined as (B.x, B.y), and the text area B is not limited to be the same as the size of the screen area A or be located in the screen area A completely; the square area C is used for determining the position of the positioning area D, and the position of the upper left corner thereof is defined as (C.x, C.y); the positioning region D is a region having a spheroidizing effect, the spheroidizing value is set to 65% (which is a parameter value in the image processing software PS), and the position is indicated by a center, defined as a center p (p.x, p.y). In the embodiment of the present invention, the radius of the positioning region D is 3 cm (which can be flexibly set, and is preferably enough to display the upper and lower 5 lines of characters), the position of the center p is (A.x + a.width/2,

a.y + a.height/2), the position of the upper left corner of the square region C is (A.x + a.width/2-positioning region D radius, A.y + a.height/2-positioning region D radius). Wherein, a.width refers to the width of the screen area a, and a.height refers to the height of the screen area a. In addition, the width b.width and height b.height of the text region B, and the width c.width and height c.height of the square region C are also shown in the figure. The width and height of the text area B are not limited to be equal to the width and height of the screen area a, respectively, and may be any other size, which is not limited in the present invention.

In the embodiment shown in fig. 2, the cursor in the positioning region D is set to be located at the center of the positioning region D, and then, when the text region B is moved, the point where the center p is located is at the position corresponding to the text region B (p.x-B.x, p.y-By); then, the setconsollecurrsorposition function is called (taking windows system as an example) to move the cursor, so that the text editing position can be positioned.

Fig. 3 is a schematic diagram of the overall implementation effect of an embodiment of the invention. As shown in fig. 3, the positioning region is used for realizing a fisheye lens effect, for example, when the text region is moved to the positioning region, the text at the middle position of the region is enlarged, the text at the edge is distorted and reduced, but the whole text content is not blocked, so that the user can conveniently judge the specific position of text editing through the whole content of the text.

Fig. 4 is a schematic diagram of an implementation effect of a cursor located at the head of a row according to an embodiment of the present invention. As shown in fig. 4, the positioning region can realize a fisheye lens effect, and the cursor can be accurately positioned at the head of the line by moving the text region. Similarly, the cursor can be accurately positioned to the top row by moving the text area, thereby solving the problem of positioning difficulty caused by the problem of the edge of the screen.

Fig. 5 is a schematic diagram of an implementation effect of a cursor located at the tail of a row according to an embodiment of the present invention. As shown in fig. 5, the positioning region can be used to accurately position the cursor to the tail of the line by moving the text region, for example, to achieve the fisheye lens effect. Likewise, the cursor may also be accurately positioned to the last line by moving the text region. When the text area is moved out of the positioning area, the cursor automatically disappears.

Fig. 6 is a schematic diagram of main blocks of an apparatus for determining a text editing position of a touch device according to an embodiment of the present invention. As shown in fig. 6, an apparatus 600 for determining a text editing position of a touch device according to an embodiment of the present invention mainly includes a positioning area generating module 601 and an editing position determining module 602.

According to an embodiment of the present invention, the edit position determination module 602 may be further configured to: the text region to be edited is moved within the positioning region by moving the text region to be edited within and/or outside the positioning region.

According to another embodiment of the present invention, a speed of moving the text region to be edited within the positioning region does not exceed a speed of moving the text region to be edited outside the positioning region.

According to the technical scheme of the embodiment of the invention, the positioning area is used for amplifying the text by performing the sphericizing treatment on the text.

According to another embodiment of the invention, the positioning area is processed by spheronization of the text to achieve magnification of the text by a fisheye lens.

According to the technical scheme of the embodiment of the invention, the positioning area is generated in the screen area of the touch equipment according to the text editing and positioning instruction, and then the text area to be edited is moved in the positioning area to determine the text editing position, so that the problem that the head line, the tail line, the top line, the tail line and the like cannot be positioned is solved; the text area can be edited by moving the text area relative to the screen area, and the text area does not need to be limited to be beyond the screen area, so that the application range is wider, and the practicability is higher; meanwhile, the positioning area realizes the twisting processing such as text amplification by performing the sphericization processing on the text, so that the characters at the position to be positioned are in the most prominent amplification state, the recognition rate is improved, meanwhile, the characters in adjacent rows cannot be shielded, the fuzzy recognition of the characters cannot be influenced, the context is more coherent, and the user experience is better.
