Problems solved by technology

[0009] 2. Excessive system resource usage
During this operation, the operation will take up more system resources
However, the excessive occupation of system resources will bring many strange problems. Such problems are highly concealed and have no fixed path, so it will be very difficult to deal with.
During the test, many faults occurred in the process of frequent key pressing. If the burden on the system caused by key pressing can be reduced, it can be predicted that such hidden faults will be greatly reduced.
[0010] 3. Slow response
Due to the above-mentioned resource occupation problem, it is necessary to wait when deleting characters, and this waiting time can be perceived by the user, which will cause poor user experience.
[0011] 4. Poor accuracy
Since you need to press the delete button continuously during the deletion process, once the control is not good, it will delete the things that you don’t want to delete, which will also cause poor user experience.

Embodiment 1

[0073] In this embodiment, the character deletion method for a terminal with a touch screen, such as figure 1 shown, including the following specific steps:

[0074] S101. Detect the contact with the touch screen, and obtain the coordinate information of the first contact point;

[0075] S102. Obtain the coordinate information of the last contact point according to the contact;

[0076] S103. Obtain character information to be deleted according to the coordinate information of the first contact point and the coordinate information of the last contact point;

[0077] S104. Perform a deletion operation on the character to be deleted.

[0078] Under a preferred embodiment, before performing all the steps, it also includes:

[0079] S100. Obtain text direction information of the input method.

[0080] In a preferred implementation manner, the traveling direction of the contact is opposite to the writing direction of the input method. That is, the touch operation on the touch ...

Embodiment approach

[0092] In a preferred embodiment, during the processing module 10 acquiring character information to be deleted,

[0093] When the abscissa of the coordinate information of the first contact point is greater than the abscissa of the coordinate information of the last contact point, obtain the character information between the first contact point and the last contact point as character information to be deleted;

[0094] When the abscissa of the coordinate information of the first contact point is equal to the abscissa of the coordinate information of the last contact point, and the ordinate of the coordinate information of the first contact point is greater than the ordinate of the coordinate information of the last contact point, obtain the characters between the first contact point and the last contact point The information is character information to be deleted.

[0095] In addition, an embodiment of the present invention also provides a terminal. For example, the terminal ...

Embodiment 2

[0117] This embodiment provides a character deletion method for a terminal with a touch screen, such as image 3 As shown, the method includes the following specific steps:

[0118] S200. Obtain the text direction information of the input method;

[0119] S201. Detect contact with the touch screen;

[0120] S202. When the traveling direction of the contact is opposite to the writing direction of the input method, acquire character information to be deleted according to the traveling track of the contact;

[0121] S203. Perform a deletion operation on the character to be deleted.

[0122]In the character deletion method provided in this embodiment, the terminal judges according to the contact between the finger or the stylus and the touch screen and in combination with the writing direction of the selected input method. When the writing direction of the input method is opposite, it is judged that the current user intends to delete the text. At this time, the terminal obtains...

Abstract

The invention discloses a character deleting method and device for a terminal having a touch screen, and a terminal. The character deleting method comprises the following steps: detecting contact with the touch screen and acquiring coordinate information of a first contact point; acquiring the coordinate information of a last contact point according to the contact; acquiring the information about to-be-deleted characters according to the coordinate information of the first contact point and the coordinate information of the last contact point; and deleting the to-be-deleted characters. When the character deleting method provided by the invention is used for deleting the characters, the deleted characters are only related to a drop point and a sliding track, thereby avoiding mistaken deletion to a certain extent and improving user experience.

Description

technical field [0001] The present invention relates to the field of portable electronic equipment, and more specifically, to a character deletion method, device and terminal for a terminal with a touch screen. Background technique [0002] In the current increasingly competitive mobile phone market, how to meet users' increasingly demanding requirements for mobile phones is an important channel for mobile phone manufacturers to seek development. Good-looking appearance, excellent brand effect, and good ease of operation have also become important reference indicators for users in addition to considering the functions and performance of mobile phones when purchasing mobile phones. Usually, the appearance and brand of mobile phones are hard conditions, which cannot be changed overnight. In this case, how to provide users with better visual experience and operating experience through mobile phone software that is relatively easy to improve has become a problem worth exploring...
