When code element surpassed 6 code elements, for example 8 code elements were arranged on the 2-9 key.After entering interface of input method, can show 6 Chinese characters on the screen, but there is not numeral (1,2,3,4,5,6) prompting before the Chinese character, can not directly import this 6 Chinese characters by the 1-6 key, must be earlier (for example: 1 key) by a definite key, numeral (1,2,3,4,5,6) occurs before making Chinese character, and then import this 6 Chinese characters by the 1-6 key.So, can not import into Chinese character by a key, must be more than the key at two.When on screen behind 1 code element key of input, showing with this code element to be 6 Chinese characters of first stroke shape, but there is not numeral (1,2,3,4,5,6) prompting before the Chinese character, by a definite key (for example: 1 key), numeral (1,2,3,4,5,6) occurs before making Chinese character, and then import this 6 Chinese characters by the 1-6 key.Promptly can select 48 Chinese characters by 3 keys.In like manner, can select 384 Chinese characters, can select 3072 Chinese characters, can select 24576 Chinese characters by 6 keys by 5 keys by 4 keys.
The frequency of utilization of each Chinese character is different, and the frequency of utilization of the few more Chinese character that shows of button is just high more, and when the average key press of the input of calculating Chinese character was counted, we just must make flexible strategy with frequency, ask the average key press number of each Chinese character.As can be seen from the above table, during by 6 keys, 6 code element 6 key word selections, 9 code element 9 key word selections are two kinds of maximum input methods of word selection.We make flexible strategy with frequency, ask the average key press number of each Chinese character, find that 6 code element 6 key word selections are average minimum by number of package.That is to say that 6 code element 6 key word selection input speeds are the fastest, and are most effective.
2) definition of employing " frame " has reduced the stroke of importing, average input code length, high input speed.
3) advantage of this input method is that also the punctuation mark input efficiency is the highest, and 6 commonly used punctuation marks only need 2 keys, the punctuation mark average key press also have only 2 several, and 6 punctuation marks commonly used can be realized touch system.
Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

Specific embodiment one, data processing equipment comprise mobile phone, phone, PDA, telepilot, palm PC and electronic dictionary etc., keypad refers to comprise the keyboard of 0-9 10 numeric keys and 12 keys of function key " *, # ", and majority also comprises other several function keys.Five basic Chinese characters strokes " horizontal, vertical, left, points, discount " of GB regulation and compound stroke " frame " is corresponding with any six keys in 12 keys respectively, and the key position on candidate item and the keypad except that basic stroke " horizontal stroke ", " erecting ", " left-falling stroke ", " right-falling stroke ", " folding " and the pairing key of compound stroke " frame " position is corresponding one by one.In the present embodiment " horizontal, vertical, left, points, discount " and " frame " respectively and " 7,8, *, 0,9, # " key corresponding one by one, candidate item respectively and " 1,2,3,4,5,6 " key corresponding one by one, be convenient to button and select." frame " is meant by the limit more than four or four and surrounds or surround substantially related stroke combination, and two angles that wherein have three limits to surround are right angle or angle of collimation, and this stroke combination is as a compound stroke input when input.For surrounding related non-sealing stroke combination (being also referred to as standard " frame ") substantially, also be defined as " frame ".
The included similar stroke of the corresponding relation of five kinds of basic strokes and compound stroke " frame " and six keys and each stroke is as shown in table 2.
Table 2
Similar stroke sound in the table 2 is not exhaustive, as long as satisfy the definition of each stroke, can calculate and do this stroke.The parts or the Chinese character that contain " frame " for example have: mouthful,, day, month, say, in, order, and, first,, the Shen, the field, by, ear, altogether, the west, bent, the tenth of the twelve Earthly Branches, halogen, in, its, directly, really, allusion quotation, four, pass through, very, summer, twenty, five, sweet, generation, slowly, the mound, inferior, just, ugly, the centre, history, the people, the official, drag, worm, year, blunt, more, bundle, string, tortoise, abundant, exempt from, thing, inferior, single, leather, card, a kind of monkey mentioned in ancient literature, expensive, heavy, promptly, ghost, Yu, flat, decline, violet, resemble, deer, dare, favour, hide, black, cage, Cao, plug, single sonorous stone, smoked, once, few, minister, the institute, the Yin Dynasty, false, red, not, with, get rid of, female, boat, body, agree, corpse,, the sixth of the twelve Earthly Branches, crust, well, open, Yin, determine, the centre, strive, then, that, the wife, exhibition, prompt, grasp, heptan, respectful, be subordinate to, Tang, hold concurrently, minister, huge, family name etc.And contain the parts of following accurate frame or Chinese character for example has horse, pleasure, tooth, hangs down, crow, bird, mortar, old man, slotting etc.
The corresponding at least a kind of coding of each Chinese character in Chinese character-coding mapping library, the formation method of this kind coding is: basic stroke " horizontal stroke ", " erecting ", " left-falling stroke ", " right-falling stroke ", " folding " and compound stroke " frame " are mapped to respectively on six key positions of keypad; For example according to table 2 correspondence,, form the coding of this Chinese character with the sequential write combination of the pairing key of each stroke position of Chinese character according to Chinese character.
Input rule for frame: promptly write the input stroke, when being input to the related stroke of shaped as frame, then all related strokes of shaped as frame imported as a stroke combination by the normal stroke order of word, then remaining stroke by normal stroke order input.
For example, Chinese character " exhibition ", according to this programme, its stroke according to order of writing strokes be " corpse,
Pie, i.e. " the circle folding is cast aside and is pressed down ", and its coding is " ##9*0 ".Chinese character " more ", according to this programme, its stroke according to order of writing strokes be " one, mouthful, one, Pie, ", i.e. " horizontal frame horizontal left-falling stroke press down ", its coding is " 7#7*0 ".Chinese character ' moon ' for example, according to this programme, its stroke according to order of writing strokes be '
One ', i.e. " frame horizontal stroke ", its coding are " #7 " for example Chinese characters ' field ', according to this programme, its stroke is ' mouth,, Shu ', i.e. " frame anyhow " according to order of writing strokes, its coding is " #78 " for example Chinese character ' bird ', according to this programme, its stroke according to order of writing strokes be ' Pie,
one ', i.e. " cast aside frame point horizontal stroke ", its coding is " * #07 " for example Chinese character ' mortar ', according to this programme, its stroke according to order of writing strokes be '
One by one ', i.e. " frame is horizontal ", its coding is " #77 ".
As shown in Figure 1, digital processing unit comprises keypad, control module, query unit as input block, stores the storage unit and the display unit of Chinese character-coding mapping library, keypad is used to import the coding of Chinese character, the key hyte that control module receives input merges the control query unit according to finding out the candidate item that comprises this key bit pattern in the Chinese character-coding mapping library of this key bit pattern in storage unit, control module control display unit show candidate item.
In the time will in digital processing unit, importing Chinese character, according to the order of writing strokes of Chinese character, the pairing key of each order of strokes observed in calligraphy position to be imported in proper order, query unit constantly finds out candidate item, and display unit constantly shows new candidate item.The key position of input is many more, i.e. Shu Ru key bit pattern is long more, and candidate item is few more.This candidate item is promptly selected and is imported in the input of the pairing key of this candidate item position.
The ordering of each candidate item is the frequency of utilization ordering from big to small according to Chinese character, frequency of utilization is big be arranged in before.The frequency of utilization of Chinese character can know from many approach, for example number of site." modern Chinese frequency dictionary " that " the comprehensive usage frequency table of modern Chinese character " language teaching research institute of Beijing Language Institute writes
As shown in Figure 2, for example, in the time of importing Chinese character " greatly ", according to the Chinese-character stroke order, its coding is " 7*0 ", and the first stroke input " horizontal stroke " i.e. is " 7 ", and the candidate item that this moment, display unit showed is:
1 one 2 not 34 have 5 come 6 big
Enter key position " 6 ", " greatly " are selected and are input in the data processing equipment, be presented on the display unit.If do not find needed Chinese character at this page or leaf, can continue to import the pairing key of next stroke position, reduce candidate item; Can also search by the page turning key page turning.
In order further to accelerate input speed, when switching to the Chinese character input state, display unit directly shows six candidate commonly used, Chinese character relatively commonly used can be made as this six candidate, six candidate respectively with keypad on " 1,2,3,4,5,6 " six key positions corresponding one by one.The pairing numeral of button input candidate, promptly defeated as Chinese character.
Specific embodiment two, different with embodiment one be, the coding that in Chinese character-coding mapping library, also comprises radicals by which characters are arranged in traditional Chinese dictionaries, when receive be key position after second key position or second the key position time maybe when first key position of reception is " frame " pairing key position, query unit also with key bit pattern and the contrast of the radical-code in Chinese character-coding mapping library imported, finds out the candidate item that comprises this key bit pattern in the radical-code; The candidate item that shows comprises candidate Chinese character and candidate's radicals by which characters are arranged in traditional Chinese dictionaries, and candidate Chinese character and candidate's radicals by which characters are arranged in traditional Chinese dictionaries sort according to frequency of utilization, and frequency of utilization is big is arranged in the front.In actual use, the frequency of utilization of Chinese character is with embodiment one, and the computing method of the frequency of utilization of radicals by which characters are arranged in traditional Chinese dictionaries are:
A: the frequency of radicals by which characters are arranged in traditional Chinese dictionaries;
N: the number that contains all Chinese characters of these radicals by which characters are arranged in traditional Chinese dictionaries;
R: correction factor;
Ai: the frequency that contains the single Chinese character of these radicals by which characters are arranged in traditional Chinese dictionaries.
Radicals by which characters are arranged in traditional Chinese dictionaries in the candidate item are represented with underscore.For example, during the first stroke input " frame ", the radicals by which characters are arranged in traditional Chinese dictionaries of " frame " then can appear containing:
1
Mouthful 2
