Description
Technical Field
The invention relates to the technical field of touch control, in particular to a terminal.
Background
When a user edits characters by using the terminal, a text box is displayed on an input interface of the terminal, and the text box contains the input characters and a cursor for indicating the current character input position. Along with the input operation of the user, the cursor can move along the direction of increasing characters. If the user finds that the edited characters are wrong, the user needs to move the cursor to the wrong position to delete the characters.
The method of moving the cursor usually includes directly clicking the target position to prompt the cursor to move the position, when the text in the text box is very small, the user may easily touch the adjacent position by mistake, and the target position may be clicked by multiple clicks. The prior art provides a scheme for moving a cursor, which automatically pops up a magnifying glass when detecting that a user continuously touches an input text for more than 1 second, so as to magnify the text touched by the user and assist the user in moving the cursor to a target position. Although the prior art improves the accuracy of cursor movement operation, each time a user moves a cursor for at least 1 second, a large amount of text modification operations waste the time of the user, and dragging the cursor after continuously touching for more than 1 second affects the efficiency of cursor movement operation, and also has the disadvantage of inconvenient operation.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a method for positioning a cursor, wherein an implementation main body of the method is a terminal with a touch screen, specifically a mobile phone, a pad, a portable computer and other portable mobile terminals, and also a desktop computer working through an external touch screen display, a set-top box working with the touch screen display or a set-top box all-in-one machine and other terminals with a touch screen display function. Specifically, the method of the embodiment of the present invention may include: when the terminal detects the sliding operation of a user on the touch screen, locking a cursor in a text input area to an initial cursor position where the cursor is located on a display interface before the sliding operation occurs; dragging the text in the text input area according to the sliding operation, and determining the insertion position of the cursor in the dragged text as a target insertion position; and inserting the cursor into the target insertion position and unlocking the cursor. The scheme of the embodiment of the invention can improve the efficiency of cursor positioning operation.
The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, an embodiment of a method for positioning a cursor provided by the present invention may include the following steps:
step S110, when the terminal detects the sliding operation of the user on the touch screen, the terminal locks the initial position of the cursor on the display interface where the cursor is before the sliding operation occurs in the text input area;
step S111, the terminal drags the text in the text input area according to the sliding operation and determines the insertion position of the cursor in the dragged text as the target insertion position;
in step S112, the terminal inserts the cursor into the target insertion position and unlocks the cursor.
The embodiment of the invention supports the user to drag the text in the text input area, thereby achieving the purpose of changing the cursor position in the text input area. As shown in fig. 5, the text input area, in which some words have been input, needs to move the cursor to the target position when the input text is found to be wrong or more words need to be added to the input text, for example, the target insertion position required by the user may be between "and" ok ".
Specifically, when a user operates on the touch screen through a contact medium (such as a finger, a touch pen, and the like), the terminal can immediately acquire coordinates of a starting point of the display interface corresponding to a contact point of the touch medium on the touch screen, and when the touch medium slides on the touch screen, the terminal can detect a sliding operation to be performed on the touch screen by the user according to the touch condition acquired through the touch screen, and record a sliding track formed by coordinates of each contact point corresponding to the display interface, the sliding track being generated in the sliding operation process.
Further optionally, in the cursor movement scheme provided in the embodiment of the present invention, a user is supported to indirectly reposition the cursor by moving a text in the text input area, and the time when the sliding operation is detected is used as a trigger point to trigger the cursor repositioning operation, and the terminal in the embodiment of the present invention may specify a setting area for detecting the sliding operation, as shown in fig. 5, the terminal may set an area of the display interface corresponding to the text input area on the touch screen as the setting area, and detect whether there is a sliding operation for performing the cursor repositioning operation in the setting area. The terminal can also set the area of the touch screen corresponding to the whole display interface as a set area, and prescribe that when the text input area is displayed on the display interface, the sliding operation acquired from the touch screen is regarded as the cursor repositioning operation in the text input area.
Further optionally, when the terminal detects a sliding operation of the user on the touch screen, the specific implementation of the operation of locking the cursor in the text input area to the initial position of the cursor where the cursor is located on the display interface before the sliding operation occurs may include: the terminal records a track generated in the process of operating on the touch screen by a user through the touch screen, and determines the initial position of a cursor when the initial point position of the track is obtained; the terminal judges whether the operation of the user on the touch screen is sliding operation or not according to the track; and if the operation of the user on the touch screen is judged to be sliding operation, locking the cursor at the initial position of the cursor. For example, referring to fig. 5, when the terminal detects a sliding operation, it may determine that the initial position of the cursor is between "packet" and "ha" according to the recorded starting point position, and lock the cursor at the initial position of the cursor.
Further optionally, in the dragging process of dragging the text in the text input area by the terminal according to the sliding operation, the text in the preset range corresponding to the cursor can be displayed in an enlarged manner on the display interface. The effect of the enlarged display can be referred to fig. 6 to 9 provided later.
Further optionally, the specific implementation of the operation of the terminal dragging the text in the text input area according to the sliding operation may include: the terminal saves the track generated by the sliding operation recorded by the terminal; and dragging the text in the text input area by the terminal according to the track. If the track generated by the sliding operation is a track from left to right, the terminal moves the text by a corresponding distance to the right, if the track generated by the sliding operation is a track from right to left, the terminal moves the text by a corresponding distance to the left, if the track generated by the sliding operation is a track from bottom to top, the terminal moves the text by a corresponding distance to the top, if the track generated by the sliding operation is a track from top to bottom, the terminal moves the text by a corresponding distance to the bottom, and further, if the end point of the track generated by the sliding operation is the position of the oblique line direction relative to the start point, the text will finally move according to the oblique line direction relative to the start point of the end point.
Further optionally, the specific implementation of the operation of dragging the text in the text input area by the terminal according to the track may include: the terminal determines a sliding vector according to the position of the end point and the position of the start point of the track; and dragging the text by the terminal according to the sliding vector. That is, the magnitude and direction of the sliding vector will determine the final movement position of the text.
Further alternatively, when the terminal performs the text movement operation according to the sliding vector, the module of the sliding vector may be directly used as the distance basis for the text movement, for example, a scale may be preset, and a proportional relationship between the sliding vector module and the final text movement distance may be established, and if the proportional relationship may be set to be 1:1, the performing of the text movement operation according to the sliding vector by the terminal may include: the terminal determines the dragging direction and the vector mode for dragging the text based on the sliding vector; and dragging the text by the terminal along the dragging direction by a distance equal to the vector modulo. For example, referring to fig. 6 together, when the target insertion position is between "still" and "existing", the terminal may determine that the direction of the sliding vector is to the right through the sliding operation, and the modulus of the sliding vector is 3 characters, the terminal moves the text to the right by a distance of three characters, and indirectly repositions the cursor between "still" and "existing" by moving the text.
Further alternatively, after the terminal inserts the cursor into the target insertion position and releases the lock on the cursor, the text needs to be moved back to the position where the text was before being dragged, wherein the cursor remains at the target insertion position and moves along with the text. Referring also to fig. 7, after the terminal indirectly repositions the cursor, the text and the cursor can be moved back together, and the cursor on the interface shown in fig. 7 moves along with the text and is always positioned between "still" and "there".
Further alternatively, when the terminal implements the operation of moving the text according to the sliding vector, the terminal may also refer to only the direction of the sliding vector and move the text by a distance of a specified character along the direction of the sliding vector, for example, the implementation of the operation of moving the text according to the sliding vector by the terminal may include: the terminal determines the dragging direction for dragging the text based on the sliding vector; when the determined dragging direction is leftward, the terminal moves the text leftward by a distance of one character; or when the determined dragging direction is rightward, the terminal moves the text by a distance of one character rightward; or when the determined dragging direction is upward, the terminal moves the text by a distance of one line upward, or when the determined dragging direction is downward, the terminal moves the text by a distance of one line downward. For example, based on the interface shown in fig. 7, when the detected dragging direction is downward, the terminal directly sets the position corresponding to the cursor in the previous line as the target insertion position, and moves the text by a distance of one line downward, the effect after the movement can be referred to fig. 8, and in addition, when the movement is finished and the contact medium leaves the set range, the terminal moves the cursor back to the text, and the final display effect is shown in fig. 9.
Further optionally, the specific implementation of the operation of the terminal determining the dragging direction for dragging the text based on the sliding vector may include the terminal determining an angle α of the sliding vector, if 2k pi-pi/4 < α ≤ 2k pi + pi/4, the terminal determining the dragging direction as right, if 2k pi + pi/4 < α ≤ 2k pi +3 pi/4, the terminal determining the dragging direction as up, if 2k pi +3 pi/4 < α ≤ 2k pi +5 pi/4, the terminal determining the dragging direction as left, and if 2k pi +5 pi/4 < α ≤ 2k pi +7 pi/4, the terminal determining the dragging direction as down (where k is an integer and pi is a circumferential rate).
The method and the device for detecting the cursor target insertion position of the touch screen comprise the steps that the sliding operation of a user on the touch screen is detected, the text of a text input area is dragged according to data generated by the sliding operation, the target insertion position of the cursor is finally confirmed, and the cursor is inserted into the confirmed target insertion position; in the moving process, the area where the cursor is located is enlarged and displayed, and the user can conveniently check the cursor. The scheme of the embodiment of the invention improves the efficiency of cursor positioning operation.
