Embodiment Construction

[0034] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited by the exemplary embodiments described here.

[0035] figure 1 A flow chart of an input error correction method for touch screen input executed by a computer according to an embodiment of the present application is shown.

[0036] Such as figure 1 As shown, in step S110, the coded character string input by the user and the input coordinates and time of each character are received by using the touch information on the touch screen.

[0037] Every time the user touches, there are the coordinates, time, and corresponding characters of the touch. After recording these, the coded character string input b...

Abstract

The invention discloses an input error correction method executed by a computer. The input error correction method comprises the following steps: receiving a coded character string input by a user and input coordinates and time of each character by utilizing touch information on a touch screen; according to the received character string information, analyzing coordinates and frequency of adjacent touch interaction, and analyzing the possibility that a certain touch interaction is mistakenly touched due to hand tremor; obtaining corresponding candidate items through conversion of the mistaken touch possibility of adjacent touch interaction coordinate frequency analysis and the received coded character string. Compared with a common input method character string correction method, the invention has the advantages that the influence of mistaken touch caused by tremor on the input character string can be effectively reduced, and the problems of large touch deviation and excessive touch caused by tremor can be effectively solved; the processed candidate items can effectively filter invalid input of the user and correct inaccurate input, and a character string more conforming to expectation is provided for the user, so that the user is helped to improve the error-tolerant rate in the using process, the number of times of deleting input characters is reduced, and the input speed is increased.

Description

technical field [0001] The present invention generally relates to the technical field of computer information input, in particular to a method and device for coding error correction during information input. Background technique [0002] For users who use English, Chinese and other languages ​​to input text on smart touch screen devices, they generally need to interact with smart terminals through input method programs: The set standards such as language, keyboard, and algorithm transform the input string mapping into candidates in the corresponding language, so that the user can confirm the input information. [0003] Due to the non-discrete nature of the touchable coordinates of the user on the touch screen, the character string entered by the user and the target string often have errors due to inaccurate clicks. Therefore, unlike mechanical keyboards, touch screen virtual keyboards usually require fuzzy button coordinates. , that is, to correct the error clicked by the u...
