Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
Currently, when a user inputs information through a mobile terminal, the user usually inputs information by using an on-screen soft keyboard. And a delete key is usually provided on the input interface of the current input method. In the related art, when a user deletes a character in an input content, the user generally needs to move a cursor to a last character to be deleted, and then click a deletion key provided on an input interface to delete one character again one time until all characters to be deleted before the cursor is input are deleted. Because the character is deleted back by clicking the deletion key one by one, the deletion process is time-consuming and the deletion efficiency is low.
In view of the above situation, an embodiment of the present invention provides a character deletion method. It should be noted that the execution subject of the method may be any device that supports a touch screen and supports an input panel function, and this is not particularly limited in the embodiment of the present invention, including but not limited to a mobile phone or a tablet computer. Specifically, the method comprises the following steps:
101. and detecting the sliding operation of the user in real time, and determining a sliding track corresponding to the sliding operation.
In the embodiment of the invention, the user can delete the characters by sliding on the display screen. Correspondingly, in the character input state, the device can detect the sliding operation of the user on the display screen in real time and determine the sliding track corresponding to the sliding operation.
102. And if the characters to be deleted are displayed in the preset display area and the sliding track meets the preset conditions, deleting the characters to be deleted, wherein the preset conditions comprise that the initial falling point of the sliding track is positioned on a deleting key in the input panel.
The preset display area may be used to display characters to be displayed on a screen or characters already displayed on the screen, which is not specifically limited in the embodiment of the present invention. The position of the preset display area may be above the input panel, which is not particularly limited in the embodiment of the present invention. The characters to be deleted may be all characters before the cursor is input in the preset display area, may also be all characters after the cursor is input in the preset display area, and may also be all characters displayed in the preset display area, which is not specifically limited in the embodiment of the present invention. The input panel refers to a virtual keyboard panel provided by an input method, and the deletion key is positioned on the virtual keyboard panel.
The sliding track meeting the preset condition means that the initial falling point of the sliding track is positioned on the deletion key in the input panel, namely when the user slides on the display screen, the initial contact point of the finger is the deletion key in the input panel. Based on this, the initial falling point of the sliding track corresponding to the sliding operation is located on the delete key in the input panel.
In combination with the actual application scenario, for convenience of understanding, taking the character to be deleted as the character before the input cursor as an example, if the sliding track meets the preset condition, it can be determined that the sliding track is formed by the user clicking the delete key in advance and then dragging the sliding track to other places. At this time, the character to be deleted may be deleted, that is, the character before the input cursor is deleted. It should be noted that the sliding direction of the sliding track may be any direction, and the final drop point of the sliding track may also be any position on the display screen, which is not specifically limited in this embodiment of the present invention.
According to the method provided by the embodiment of the invention, the character to be deleted is deleted after the detected sliding track meets the preset condition. Because the user only needs to slide the finger to delete the characters, the characters can be deleted without manually deleting the characters one by one, and therefore deleting efficiency can be improved, and user experience is improved.
In the actual text editing process, the user may need to delete the characters before the input cursor and may also need to delete the characters after the input cursor. In order to meet different deletion requirements of users, the sliding operation and the deletion instruction can be correlated. Accordingly, the corresponding meanings of the different sliding tracks can be predefined, so that the corresponding deleting instructions can be executed subsequently. Based on the above principle and the content of the foregoing embodiment, as an optional embodiment, the preset condition may further include that the final drop point of the sliding trajectory is located in a first area with the initial drop point as a vertex; accordingly, the embodiment of the present invention does not specifically limit the manner of deleting the character to be deleted, including but not limited to: and deleting the characters displayed before the input cursor in the preset display area.
It should be noted that, since the initial falling point of the sliding track is determined, that is, located on the delete key in the input panel, the initial falling point serves as one of the vertices of the first area no matter how the first area is defined. The deleting instruction associated with the first area is the character displayed before the input cursor in the preset display area is deleted. Accordingly, when the final drop point of the sliding track is located in the first area, the deletion instruction associated with the first area can be executed.
In addition, the shape of the first region may be a square or a circle, which is not particularly limited in the embodiment of the present invention. The relative position of the first area and the initial drop point may be set in combination with a gesture operation habit of the user, for example, the first area is located on the left side or the upper side of the initial drop point, which is not specifically limited in the embodiment of the present invention.
According to the method provided by the embodiment of the invention, the final drop point position of the sliding track is determined, and when the final drop point is in the first area, the character displayed before the cursor is input in the preset display area is deleted. Due to the fact that the user can delete the characters by controlling the position of the falling point of the sliding operation, deleting efficiency can be improved, and user experience is improved.
When the user slides on the display screen, the sliding direction is usually a straight line. Therefore, the shape and the boundary of the first region may be determined according to the sliding habit of the user. Based on the above principle and the content of the above embodiment, as an alternative embodiment, the first area may be a sector area with a preset angular arc, and the first area is located on the left side of the initial falling point.
In combination with an actual application scene, when a user slides on a display screen by taking a certain point as an initial falling point, the sliding track is a straight line by taking the initial falling point as a starting point, so that the first area is set to be a fan-shaped area with a preset angular radian, and the sliding tracks of different final falling points can be better contained. In addition, if there is another divided area in addition to the first area and the other divided area corresponds to another deletion instruction, the first area and the other divided area are set in a fan shape to facilitate the division from each other and to conform to the sliding operation habit of the user. The predetermined angle may be set according to a requirement, for example, 90 degrees, and this is not specifically limited in the embodiment of the present invention.
Taking the device as a mobile phone as an example, the position and shape of the first area can be referred to fig. 2. As shown in fig. 2, the first area is a sector area, and the vertex (i.e., the initial landing point) of the sector area is located on the delete key. In addition, the first area is located to the left of the initial landing point. For ease of understanding, the procedure of the deletion operation will be described by taking the slide trajectory as a straight line as an example. Specifically, the user may first put a finger on the delete key, and if it is detected that the user presses the delete key (i.e., it is detected that the initial falling point is located on the delete key) and slides to the left, and the final falling point of the sliding track is located in the first area, the character displayed before the input cursor in the preset display area may be deleted.
It should be noted that, in the above process, when it is determined that the final drop point of the sliding track is located in the first area, the character displayed before the input cursor in the preset display area is deleted. In addition to this situation, when it is determined that the entire sliding track is located in the first area, the character displayed before the cursor is input in the preset display area may be deleted, which is not specifically limited in the embodiment of the present invention. At this time, the preset condition further includes that the sliding track is located in the first area. It should be further noted that, since the character displayed before the input cursor in the preset display area is deleted, the first area is located on the left side of the initial drop point, and the operation habit of the user is relatively met. Of course, in an actual implementation process, the first area may also be located on an upper side, a lower side, a right side, or other positions of the initial landing point, which is not specifically limited in the embodiment of the present invention.
As can be seen from the above, deleting the character displayed before the cursor is input in the preset display area (i.e. deleting the command) may correspond to a left-sliding operation with the initial drop point as the starting point and the final drop point located in the first area. In order to avoid that the user mistakenly triggers the left-sliding operation, after the initial falling point of the sliding track is detected to be located on the deletion key in the input panel (namely, the user presses the deletion key), whether the user moves the gesture into the first area within the specified time length can be further judged. If the user moves the gesture to the first area within the specified duration, whether the final drop point of the movement track is located in the first area can be further judged. The specified time period may be 800 milliseconds, which is not specifically limited in this embodiment of the present invention.
According to the method provided by the embodiment of the invention, the first area is set to be the sector area of the preset radian angle and is positioned on the left side of the initial falling point, so that a user can delete the characters displayed before inputting the cursor in the preset display area in a leftward sliding mode. The mode of deleting characters by leftward sliding operation is more in line with the operation habit of the user, so that the user experience can be improved.
As can be seen from the above description of the embodiments, in the actual text editing process, the user may need to delete the character before the input cursor or delete the character after the input cursor. In addition to deleting the process of displaying characters before the input cursor, the user may also delete characters displayed after the input cursor within the preset display area. For this situation, based on the content of the foregoing embodiment, as an optional embodiment, the preset condition further includes that the final drop point of the sliding track is located in a second area with the initial drop point as a vertex; accordingly, deleting the character to be deleted includes: and deleting the characters displayed after the cursor is input in the preset display area.
It should be noted that the second region is different from the first region in the above-described embodiment, and there is no overlapping region in the division between the first region and the second region. In addition, since the initial falling point of the sliding track is determined, namely, is located on the delete key in the input panel, the initial falling point is used as one vertex of the second area no matter how the second area is defined. The deleting instruction associated with the second area is the character displayed after the input cursor in the preset display area is deleted. Accordingly, when the final drop point of the sliding track is located in the second area, the deletion instruction associated with the second area can be executed.
In addition, the shape of the second region may be a square or a circle, which is not particularly limited in the embodiment of the present invention. The relative position of the second area and the initial drop point may be set according to a gesture operation habit of the user, for example, the second area is located on the lower side or the right side of the initial drop point, which is not specifically limited in the embodiment of the present invention. It should be further noted that, when deleting a character displayed after the input cursor, all characters after the input cursor may be directly deleted, or a user may trigger a character deleting operation every time the user performs a sliding operation, which is not specifically limited in this embodiment of the present invention. It should be noted that the sliding operation herein needs to satisfy the preset condition specified by the embodiment of the present invention, that is, the initial falling point of the sliding track is located on the delete key in the input panel, and the final falling point of the sliding track is located in the second area.
According to the method provided by the embodiment of the invention, the final drop point position of the sliding track is determined, and when the final drop point is in the second area, the characters displayed after the cursor is input in the preset display area are deleted. Due to the fact that the user can delete the characters by controlling the position of the falling point of the sliding operation, deleting efficiency can be improved, and user experience is improved.
In addition, since the characters after the input cursor can be deleted one by the sliding operation, all the characters after the input cursor can be directly deleted, and the deletion efficiency can be further improved.
When the user slides on the display screen, the sliding direction is usually a straight line. Therefore, the shape and the boundary of the second region may be determined according to the sliding habit of the user. Based on the above principle and the content of the above embodiment, as an alternative embodiment, the second area may be a sector area with a preset angle radian, and the second area is located below the initial landing point.
Like the first area, when the user slides on the display screen with a certain point as the initial falling point, the sliding track is usually a straight line with the initial falling point as the starting point, so that the second area can be also set as a fan-shaped area with a preset angle radian, and the sliding tracks with different final falling points can be better included. The first area and the second area correspond to different deleting instructions, the first area corresponds to the deleted character displayed before the input cursor, and the second area corresponds to the deleted character displayed after the input cursor. The first area and the second area are both arranged in a fan shape, so that the first area and the second area are favorably distinguished from each other and accord with the sliding operation habit of a user. The predetermined angle may be set to 90 degrees, which is not limited in this embodiment of the present invention.
Taking the device as a mobile phone as an example, the position and shape of the second area can be referred to fig. 3. As shown in fig. 3, the second area is a sector area, and the vertex (i.e., the initial landing point) of the sector area is located on the delete key. In addition, the second area is located below the initial landing point. For ease of understanding, the procedure of the deletion operation will be described by taking the slide trajectory as a straight line as an example. Specifically, the user may first put a finger on the delete key, and if it is detected that the user presses the delete key (i.e., it is detected that the initial falling point is located on the delete key) and slides down, and the final falling point of the sliding track is located in the second area, the character displayed after the cursor is input in the preset display area may be deleted.
It should be noted that, in the above process, when it is determined that the final drop point of the sliding track is located in the second area, the character displayed after the cursor is input in the preset display area is deleted. In addition to this situation, when it is determined that the entire sliding track is located in the second area, the character displayed after the cursor is input in the preset display area may be deleted, which is not specifically limited in the embodiment of the present invention. At this time, the preset condition further includes that the sliding track is located in the second area. It should be noted that, since the characters displayed after the input cursor in the preset display area is deleted, the second area is located below the initial drop point, and the operation habit of the user is relatively met. Of course, in an actual implementation process, the second area may also be located at the right side of the initial landing point or at other positions, which is not specifically limited in this embodiment of the present invention.
As can be seen from the above, deleting the character displayed after the cursor is input in the preset display area (i.e. deleting the command) may correspond to the sliding-down operation with the initial falling point as the starting point and the final falling point located in the second area. In order to avoid that the user triggers the sliding operation by mistake, after detecting that the initial falling point of the sliding track is positioned on the deletion key in the input panel (namely, the user presses the deletion key), the user can further judge whether the user moves the gesture into the second area within the specified time length. If the user moves the gesture to the second area within the specified duration, whether the final drop point of the movement track is located in the second area can be further judged. The specified time period may be 800 milliseconds, which is not specifically limited in this embodiment of the present invention.
According to the method provided by the embodiment of the invention, the second area is set to be the sector area of the preset angular radian, and the second area is positioned at the lower side of the initial falling point, so that a user can delete the characters displayed after the cursor is input in the preset display area in a downward sliding mode. The mode of deleting the characters by downward sliding operation is more in line with the operation habit of the user, so that the user experience can be improved.
Considering that some users are used to delete the character before the input cursor by pressing the delete key for a long time, the method provided by the embodiment of the invention also supports the deletion of the character by pressing the delete key for a long time. When the user deletes the character by pressing the delete key for a long time, the character is deleted one by one. At present, when a user deletes characters back by long-time pressing operation, the characters are usually deleted one by one according to a fixed character deletion interval time. For example, if the character deletion interval time is 1 second, the user may delete one character every 1 second when pressing the deletion key for a long time until the characters before the input cursor are deleted. Because of the fixed character deletion time interval, when the character deletion time interval is short, if the user deletes fewer characters, the user may delete the characters too quickly, which may result in the user's false deletion. When the character deletion time interval is long, if the user deletes more characters, the deletion efficiency may be reduced because the character deletion is slow.
In view of the above situation, based on the content of the foregoing embodiment, as an alternative embodiment, an embodiment of the present invention further provides a method for deleting a character by pressing a delete key for a long time, including but not limited to: if the characters to be deleted are displayed in the preset display area and the long-press operation on the delete key is detected, adjusting the character delete interval time according to the long-press operation, and deleting the characters to be deleted one by one according to the character delete interval time.
When the character deletion interval time is adjusted according to the long-press operation, the character deletion interval time can be adjusted according to the duration of the long-press operation. Or, the character deletion interval time may also be adjusted according to the application strength of the long press operation, which is not specifically limited in this embodiment of the present invention.
According to the method provided by the embodiment of the invention, the character deletion interval time can be adjusted according to long-time pressing operation, and the character is not required to be deleted back according to fixed interval time, so that the character deletion back speed can be uniformly adjusted, and the user experience is improved.
Based on the content of the foregoing embodiment, as an alternative embodiment, the embodiment of the present invention does not specifically limit the manner of adjusting the character deletion interval time according to the long press operation, and includes but is not limited to: adjusting the character deletion interval time in real time according to the duration of the long press operation; wherein, the longer the duration of the long press operation, the shorter the character deletion interval time.
Specifically, the character deletion interval time may be adjusted according to the following formula:
the delay represents a time interval from the completion of the deletion of the previous character to the deletion of the next character, that is, a character deletion interval time. t represents the time from when the character is deleted for the first time, that is, the time from when the sliding track is detected to satisfy the preset condition to when the deletion of the first character is started. As can be seen from the above formula, the longer the long pressing operation duration is, the shorter the character deletion interval time is, the faster the character deletion is. It should be noted that, when the long pressing operation duration is longer, it indicates that the characters that the user may need to delete back are more, so as to shorten the character deletion interval time, and enable the user to delete the unnecessary characters more quickly.
According to the method provided by the embodiment of the invention, the character deletion interval time is adjusted in real time according to the duration of the long-press operation, so that the character deletion interval time can be automatically adjusted based on the possible deletion requirements of a user, and further the user experience can be improved.
Based on the content of the foregoing embodiment, as an optional embodiment, before deleting the character displayed in the preset display area, the method further includes: and if the characters to be deleted are displayed in the preset display area and the detected sliding track meets the preset condition, displaying a deletion prompt.
The deletion prompt may be presented in a manner of a text bubble or a text box, which is not specifically limited in this embodiment of the present invention. For example, a "clear" two-word text bubble may be displayed near the delete key to prompt the user that a delete operation is to be performed. After the deletion prompt is displayed, if the slide operation is continued, the slide trajectory continues to extend. And if the sliding track continuously meets the preset condition in the extending process, continuously displaying a deletion prompt. If the sliding track suddenly does not meet the preset condition in the extending process, the display of the deletion prompt can be stopped until the sliding track meets the preset condition.
According to the method provided by the embodiment of the invention, the deletion prompt is displayed before the characters displayed in the preset display area are deleted. The user can be reminded that the deleting operation is about to be carried out, so that the user experience can be improved.
Based on the content of the above embodiment, as an optional embodiment, the preset display area is an input box in the current information input interface, or an area to be screened in the input panel, or an associated character display area in the input panel.
For the convenience of understanding, the character input process in the above three cases will now be described with reference to the practical application scenario. Taking the pinyin input method adopted by a user as an example, when the user inputs characters, the user usually needs to input pinyin characters first, and the input method can display the input pinyin characters and corresponding Chinese characters in a region to be displayed on a screen in an input panel. After the user confirms the Chinese character to be input in the screen-on-standby area, the Chinese character confirmed by the user is displayed in the input box, and the associated Chinese character which is possibly accepted after the Chinese character is displayed in the associated character display area. If the user finds that the associated character display area displays the Chinese character which the user wants to input next, the user can directly confirm in the associated character display area without inputting the Chinese character again, and the associated Chinese character confirmed by the user is also displayed in the input box and is displayed behind the Chinese character input by the user before.
If the current user does not prepare to input Chinese characters, only the Chinese characters input by the user are displayed in the input box, and the current state can be defined as an idle state. If the user inputs pinyin to prepare for inputting Chinese characters, the region to be displayed on the screen displays the pinyin input by the user and corresponding optional Chinese characters, and the current state at the moment can be defined as an input state. If the user confirms the Chinese character to be input in the screen waiting area, the Chinese character confirmed by the user is displayed in the input box, the associated Chinese character is displayed in the associated character display area, and the current state can be defined as the associated state.
Based on the above definitions and the contents of the above embodiments, as an optional embodiment, the delete key is used to delete the character displayed in the input box; in the input state, the deleting key is used for deleting characters displayed in the screen area to be displayed; in the associated state, the delete key is used to delete the character displayed in the associated character display area.
Specifically, in the idle state, the user can delete the input Chinese characters in the input box through sliding operation. With the above embodiment, the user may delete the chinese character before the input cursor in the input box by the left-sliding operation, and delete the chinese character after the input cursor in the input box by the down-sliding operation. Similarly, in the input state, the user may delete the pinyin character before the cursor is input in the region to be displayed on the screen through the left-sliding operation, and delete the pinyin character after the cursor is input in the region to be displayed on the screen through the down-sliding operation. In the association state, the user can delete the associated Chinese character before the input cursor in the association character display area through the left-sliding operation, and delete the associated Chinese character after the input cursor in the association character display area through the down-sliding operation.
It should be noted that there is no input cursor in the on-screen area and the associated character display area of some input methods, that is, the user cannot edit characters in both areas, but only confirms them. In this case, if the current state is the input state, the user may delete the pinyin character displayed in the region to be displayed on the screen by a left-handed swipe operation. Because the pinyin characters input by the user are deleted by the user, the optional Chinese characters corresponding to the pinyin characters in the screen waiting area can be deleted. At the same time, the current state will jump from the input state to the idle state. It should be noted that the left-sliding operation in the process of deleting the pinyin character may also be replaced by a down-sliding operation, a right-sliding operation, or an up-sliding operation, and the like, and the user may set the left-sliding operation, the right-sliding operation, or the up-sliding operation according to the habit of the user, which is not specifically limited in this embodiment of the present invention.
If the current state is the association state, the user can delete the associated Chinese characters displayed in the association character display area through left-sliding operation. At the same time, the current state will jump from the association state to the idle state. It should be noted that the left-sliding operation in the process of deleting the associated chinese character may also be replaced by a down-sliding operation, a right-sliding operation, or an up-sliding operation, and the user may set the left-sliding operation, the right-sliding operation, or the up-sliding operation according to the habit of the user, which is not particularly limited in the embodiment of the present invention.
According to the method provided by the embodiment of the invention, because a plurality of areas in the input panel can support a character deleting mode of sliding operation, the character deleting efficiency can be improved.
Based on the content of the foregoing embodiments, an embodiment of the present invention provides a character deleting device, where the device is configured to execute a character deleting method in the foregoing method embodiments, and the device includes a deleting module; wherein,
