Embodiment Construction

[0027] The embodiments of the present invention will be further described below in conjunction with the drawings and examples.

[0028] Embodiment 1 of the present invention provides a method for correcting errors on a touch screen, as shown in FIG. 1 , comprising the following steps:

[0029] Step s101, receiving an input stroke action;

[0030] Step s102 , judging that the stroke action is an erasing action according to the above-mentioned stroke action or stroke model, correcting according to the erasing action, and displaying the corrected characters of the erasing action on the touch screen.

[0031] In this step, if it is judged that the stroke motion is not an erasing motion according to the stroke motion or the stroke model, then it is judged that the stroke motion is a writing motion. Wherein, judging that the stroke action is an erasing action according to the stroke action or the stroke model includes the following steps:

[0032] When the stroke model meets the f...

Abstract

The invention discloses an error correcting method for a handwriting screen, comprising the steps that: the inputted stroke action is received; the stroke action is judged into an eliminating action according to the stroke action or the stroke type; a correcting operation is accomplished according the eliminating action; and then the character which is corrected by the eliminating action is displayed on a touch screen. The invention also discloses an error correcting system and a device for handwriting screen. By adopting the technical proposal of the invention, the character stroke which is input mistakenly can be corrected in real time, thereby speeding up the handwriting speed.

Description

technical field [0001] The invention relates to the field of intelligent terminals of communication systems, in particular to a method, system and device for error correction of a handwriting screen. Background technique [0002] With the popularization of computer technology, in the early 1990s, a new human-computer interaction technology - touch screen technology emerged. Using this technology, users only need to lightly touch the icons or text on the computer display screen with their fingers to operate the host computer, which eliminates keyboard and mouse operations and makes human-computer interaction more straightforward. Therefore, touch screen technology has become the most convenient input device for man-machine communication. [0003] At present, touch screens have been widely used in liquid crystal display modules, personal digital assistants, personal computers, household appliances, mobile phones, handheld instruments, industrial computers, POS systems, public...
