Abstract

The invention relates to a method for inputting English from 10 digital keys, mainly used in communication terminal devices such as telephone and handset. First, a commonly used word base is built and sorted according to the use frequency from high to low. Then 26 English letters are arranged on the 10 digital keys. Inputting a letter from keys shows several words on screen according to the current condition. Then, the needed word is selected; if needed word is not appeared, it can be searched in the next screen. With the second letter being input, the program automatically and optimally seeks the letter with the highest appearance probability in the same key position according to the current letter use frequency sequential arrangement so as to reduce the times of artificial selection and increase the inputting speed. The invention provides features of simple, flexible, practical, and easy for popularization.

Description

Encountered frequency preference method for inputting English with numeral keypad

One, the technical field of the invention

The invention belongs to the technical field of IT product literal input.The particularly English of numeric keypad input.

Two, background technology

The alleged numeric keypad of the present invention is meant: the 10 numeric keys with 0-9 carries out the keyboard that information is imported and carried out functional performance with the several function key.

The information products of present many use numeric keypads (as mobile phone) can be supported English input.Its method is that 26 English alphabets are distributed to 2-9 on totally 8 numerical keys.Need choose successively when importing the difference letter on the same key with the method for this key of double hit; Method is imported each letter of word in proper order like this, finishes the input of word.Therefore the stroke of word input is much higher than the word letter number.English be entered as a process that poor efficiency is loaded down with trivial details.Also there is the data proposition that letter is distributed in and makes full use of key position resource on the 0-9 10 numeric keys to raise the efficiency.But the increase of 2 key positions can not be dealt with problems at all.

Three, summary of the invention

The solution of the present invention is the word frequency characteristic according to English word, and a kind of simply and efficiently numeric keypad English input method is provided.

English word amount is very huge, but common word limited amount then, and frequency of utilization also differs widely in the common word.Method of the present invention is will use the English word loading routine always in advance, sets up character library, and arranges from high to low by frequency of utilization.When first letter of input word, still choose by traditional method double hit key position.After importing first letter, program promptly will be pressed word series arrangement frequently with the word of this beginning of letter automatically, simultaneously preceding several words will be presented on the screen and numbering, show that the number of word is decided on the big low capacity of display screen.Letter of later every input is all by when the precondition word of the beginning of input alphabet (promptly with) rearrangement with show.Appeared on the display screen as required word, then can directly choose this word, and all letters that need not to be totally lost.For meeting but the word that does not show also can turn over screen searches and choose when precondition.

Simultaneously, because the word in the character library is to arrange (rather than alphabetically arranging) frequently by word, so forward " the next letter " of ranking is the letter of probability of occurrence maximum.So rise when the input second letter, what program was given tacit consent to is the letter of probability of occurrence maximum on this key position, and the letter that ranks the first on the not necessarily same key position.Like this, from second letter, often the letter of program acquiescence is exactly the letter that the importer wants.This has just significantly reduced touch potential.Having only the acquiescence letter is not required when letter, just need choose required letter with the method or the additive method of double hit key position.

The word that does not have in the character library can be by traditional method input.

This input method also can be supported uppercase input, such as: utilize function key (suggestion is " * " keyboard) to replace " Caps Lock " key on the daily computer keyboard, realize the switching that alphabet size is write.

Special function key of the input definable in space is imported, such as: space of double hit twice " # " keyboard representative input.

The input of punctuate and other symbols can cooperate the operation of function key (suggestion is " # " keyboard) to finish.

By above-mentioned two measures---point out frequently and give tacit consent to time the position letter frequently by word (inferior position letter is meant: other letters except that the word initial), the English input speed of numeric keypad can improve several times by word.Especially how to letter long words, this input method both had alleviated the user to remembering the requirement of complicated word, had avoided the embarrassment of input error word again, and had accelerated the input speed of word! And this method simple, intuitive, do not add any auxiliary code, need not study, do not require to change existing keyboard, so very easily promote yet.

Four, description of drawings

Constitutional diagram when accompanying drawing 1 is input word " English ".

Accompanying drawing 2 is program circuit sketches of this input method.

Five, embodiment

Specify implementation method of the present invention below in conjunction with accompanying drawing.

Illustrated key letter has adopted 10 key positions to arrange, and has done optimization process.2-3 letter arranged on one key, and only 2 letters all is higher letters of frequency of utilization in the English input, can make the frequency of utilization of each key be tending towards average like this.The more important thing is this keyboard layout can compatible inventor about another invention of phonetic transcriptions of Chinese characters input---improved numeric keypad and use the Chinese character pinyin input method (keyboard and input method have been applied for patent simultaneously) of this keyboard.

The example that is input as with " English " illustrates this input method (the simulator program practical operation that input process is write according to the inventor):

1. input initial, " E " of capitalization: click " * " number key, switch to the uppercase state of input, then " E " of 2 " 2 " key inputs of double hit capitalization.The prompting high frequency words is 1early, 2earth, 3eight.

2. input subsequent character, " n " of small letter: click " * " number key again, switch the state that is fed back into lowercase, by " 5 " key, program is defaulted as letter " l ", this key input " n " of double hit.The prompting high frequency words is: 1enable, 2engineer, 3english.

Can directly choose " english ", method according to the display screen prompting this moment is that this complete word (also can use additive method to realize choosing of word) appears in long serial number key " 2 " by this speech up to the input field of screen.Also can continue 4 the remaining letters of being totally lost according to above-mentioned steps.As continue to import other letters " glish ", then can find the ranking of english on display screen in rising one by one, and the acquiescence letter of program is required letter.

(annotate: simulator program only plays the example effect, and real-life program may be done the adjustment of some parts to word frequency, method of operating etc.)

Word actual prompting in actual input process of considering 1-3 letter has little significance, so the priority ratio of short word is lower, such as an, to, are etc.; The benefit of doing like this is that long word commonly used can comparatively fast be pointed out;

Consider that numeral also is the character that often will use in the keyboard input, this input method is at keystroke continuously during greater than certain number of times, prompting be not letter, but the numeral of this digital keys correspondence itself.For the successive character of numerical character, the input of acquiescence is numeral still, can improve the input speed to numeric type character strings such as telephone numbers like this.

The frequency of word should be different according to different application, the processing speed of program is because used: 1. static array, 2. method such as initial series arrangement, so search speed is very fast, satisfy the requirement of regular handset CPU and internal memory fully to program runtime and space.

Realize the computer program that this input method is required, represent by the general flow chart shown in the accompanying drawing 2.
