Method, device and storage medium for inputting characters

A terminal device for inputting characters, comprising:

• a processor;
• a touch screen;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to perform:
• presenting a user interface on the touch screen, the user interface comprising a soft keyboard;
• identifying a location of a first touch point upon detection of a first touch acted on the soft keyboard;
• judging, based on the location of the first touch point, whether it is needed to select a plurality of candidate characters from the soft keyboard;
• when it is needed to select the plurality of candidate characters, presenting the plurality of candidate characters on a currently provided user interface, wherein a first area occupied by each of the candidate characters on the currently provided user interface is larger than a second area occupied by each of the candidate characters on the soft keyboard;
• and
• determining a target character from the plurality of candidate characters;
• wherein judging whether it is needed to select the plurality of candidate characters comprises:
• calculating a set of first touch point coordinates, the first touch point coordinates indicating a location of the first touch point;
• determining a first candidate character according to the first touch point coordinates, wherein the first candidate character represents a soft key which covers a first region where the first touch point is fallen on the soft keyboard;
• judging whether a first distance between a center point of the first region and the first touch point exceeds a preset threshold;
• and
• when the first distance exceeds the preset threshold, determining that it is needed to select the plurality of candidate characters;
• wherein determining the target character from the plurality of candidate characters comprises:
• identifying a location of a last touch point among consecutive touch points upon detection of consecutive touches acted on the plurality of candidate characters through the currently provided user interface, wherein the last touch point is a touch point where an object for providing the consecutive touches is lifted;
• and
• determining the target character according to a location of the last touch point, wherein the target character represents a soft key which covers a target region where the last touch point is fallen on the currently provided user interface.

A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a terminal device with a touch screen, cause the terminal device to perform a method for inputting characters, the method comprising:

• presenting a user interface on the touch screen, the user interface comprising a soft keyboard;
• identifying a location of a first touch point upon detection of a first touch acted on the soft keyboard;
• judging, based on the location of the first touch point, whether it is needed to select a plurality of candidate characters from the soft keyboard;
• when it is needed to select the plurality of candidate characters, presenting the plurality of candidate characters on a currently provided user interface, wherein a first area occupied by each of the candidate characters on the currently provided user interface is larger than a second area occupied by each of the candidate characters on the soft keyboard;
• and
• determining a target character from the plurality of candidate characters;
• wherein judging whether it is needed to select the plurality of candidate characters comprises:
• calculating a set of first touch point coordinates, the first touch point coordinates indicating a location of the first touch point;
• determining a first candidate character according to the first touch point coordinates, wherein the first candidate character represents a soft key which covers a first region where the first touch point is fallen on the soft keyboard;
• judging whether a first distance between a center point of the first region and the first touch point exceeds a preset threshold;
• and
• when the first distance exceeds the preset threshold, determining that it is needed to select the plurality of candidate characters;
• wherein determining the target character from the plurality of candidate characters comprises:
• identifying a location of a last touch point among consecutive touch points upon detection of consecutive touches acted on the plurality of candidate characters through the currently provided user interface, wherein the last touch point is a touch point where an object for providing the consecutive touches is lifted;
• and
• determining the target character according to a location of the last touch point, wherein the target character represents a soft key which covers a target region where the last touch point is fallen on the currently provided user interface.
