Character input method for all-purpose keyboard and processing device thereof

Abstract

The invention discloses a character input method for an all-purpose keyboard, which comprises the following steps of: responding the clicking input for a key by a user, and generating and recording the key value of the key and the coordinate of a clicking point; computing the keying probability of all candidate keys according to the key value and the coordinate, and determining a keying sequence, wherein the candidate keys comprise a clicked key and a plurality of character or number keys adjacent to the clicked key; searching the word frequency of a word corresponding to each key value in the keying sequence; carrying out weighing computation for the keying probability of each key value and the word frequency of the word corresponding to the key value in the keying sequence; and sequencing the weighing computation results of all words so as to obtain a candidate word sequence. The invention also discloses a character input processing device which comprises a receiving unit, a probability computing unit, a word frequency inquiry unit and a weighing computation unit. The invention comprehensively considers the word frequencies of the words and further improves the input speed.

Description

technical field [0001] The invention relates to a character input method and device, in particular to a character input method for a full-function keyboard and a processing device thereof. Background technique [0002] With the development of information technology, people increasingly need to use smart handheld devices for human-computer interaction, and the input method is an effective means to solve language input. The full-featured keyboard, that is, the QWERTY keyboard, can be conveniently used to type text and effectively improve the input speed, so it is widely used in various smart handheld devices. [0003] At present, in the input method applied to the QWERTY keyboard, the user inputs the key sequence to the smart handheld device through the QWERTY keyboard, and the smart handheld device provides the user with a series of words as candidate words by analyzing the input key sequence, and then the user chooses from the candidate words Select the desired word from th...

AI Technical Summary

Problems solved by technology

[0004] First, the user may have made a keystroke error due to factors such as unskilled operation of the QWERTY keyboard or the QWERTY keyboard being too small, and the current input method cannot correct and compensate the user's keystroke error, and the user can only delete the original input characters , re-enter new characters, reducing the operating efficiency

[0005] For example, in a QWERTY keyboard, the "S" key is adjacent to the "D" key. When the user wants to input the "D" key, but the actual position of the key is the "S" key, the character generated by the key is the same as the "S" key. Words related to the "key cannot be used as candidate characters required by the user

At this time, the user can only give up this operation, d
