Description
Technical field
The present invention relates to Tibetan information processing technology, the particularly keyboard coding input of Tibetan language on the mobile message such as mobile phone, panel computer treatment facility.
Background technology
Along with improving constantly of information processing capability, mobile phone progressively expands to online from the basic function such as original to make a phone call, send short messages, send out letter micro-, play games, take a picture, see the additional functions such as video, and along with the continuous enhancing of basic function and the continuous increase of New function, the quantity of mobile phone user also constantly increases, the quantity of a lot of regional mobile phone user just close to or exceeded the All population capacities of this area.Owing to being easy to carry about with one and stronger processing power, the growth rate of panel computer user also clearly.Along with mobile phone and the continuous of panel computer are popularized, use the quantity of the Tibetan user of these mobile message treatment facilities also in continuous increase, but lack a kind of keyboard layout and the input system that on these mobile message treatment facilities, Tibetan language can be inputted rapidly and accurately at present.
There are some defects in existing Tibetan language keyboard layout, main cause has: one is that the number ratio of Tibetan language letter is more, and local Tibetan language and Brahma-sutra Tibetan have 41 consonants and 15 vowels; Two is that part consonant exists form of distortion, such as: letter
as under add consonant time be deformed into
letter
as on add consonant time be deformed into
and be deformed into when adding consonant under conduct
three is not only can left and right combination can also combine up and down between Tibetan language letter, when combining up and down except ground floor consonant, and all the other each layer letter not occupy-places.Therefore, for consonant, not only need to distinguish it whether occupy-place also need to distinguish it and whether be out of shape, that is, four kinds may be had at most to manifest form for Tibetan language consonant and occupy-place is indeformable, the indeformable and not occupy-place distortion of occupy-place distortion, not occupy-place.Number of letters is more, subalphbet exists form of distortion and the factor such as can to combine up and down between letter makes the input through keyboard of Tibetan language need more key total, but key mapping sum is limited in a keyboard layout, this makes the input through keyboard more complicated of Tibetan language, and result in some defects of existing Tibetan language keyboard layout.
Existing Tibetan language keyboard layout is briefly introduced below for Tibetan language keyboard layout Tibetan (PRC).Tibetan (PRC) is each consonant, and each manifests form and gives a key mapping, each like this consonant at least needs two key mappings, represents occupy-place (spacing) and not occupy-place (nonspacing) two kinds of forms respectively; Indivedual consonant even needs four key mappings, such as: letter
need four key mappings, represent four kinds of forms such as the indeformable and not occupy-place distortion of occupy-place indeformable, occupy-place distortion, not occupy-place respectively.Therefore, Tibetan (PRC) is utilized to input whole Tibetan language character listed by three National standard national standards such as baseset, superset A and superset B and symbol needs 192 key mappings.In order to obtain so numerous key mappings, Tibetan (PRC) is provided with Pyatyi keyboard: Master Keyboard (Regular Keyboard), m keyboard, M keyboard, shift keyboard and CtrlAltShift keyboard.
There are some obvious defects in Tibetan language keyboard layout Tibetan (PRC): one is that keyboard shift is frequent, the Tibetan language syllable of 75% is about had to have a not occupy-place consonant at least, and the input of not occupy-place consonant needs to be switched to m keyboard and just can complete, between Master Keyboard and m keyboard, switch the further raising that govern input speed too frequently; Two is look for word difficulty, and because 192 characters and symbol are distributed on Pyatyi keyboard, user remembers and the layout being familiar with this Pyatyi keyboard needs to pay larger study cost, is difficult to find required alphabetical key mapping at short notice fast; Three is that button process is complicated, such as: need to press Ctrl, Alt key, shift key and i key simultaneously and could input a vowel on CtrlAltShift keyboard
four is key mapping conflicts, Ctrl, Alt key, shift key has been taken during the shortcut of operating system and many common application software is arranged, therefore, utilize the CtrlAltShift input through keyboard Tibetan language character of Tibetan (PRC) that key mapping conflict can be caused.Due to the existence of above-mentioned several respects defect, Tibetan (PRC) is utilized to input Tibetan language very inconvenient.
It should be noted that, Tibetan (PRC) utilizes QWERTY keyboard to computer input Tibetan language character and symbol, if realize identical input object on mobile message treatment facility, then above-mentioned several defect will become more obvious.This is because mobile message treatment facility generally all uses on-screen keyboard, but due to the restriction by screen size, in on-screen keyboard, the quantity of key mapping can be subject to strict restriction: be generally no more than four lines, and often row is no more than 10 key mappings.
In sum, there are some obvious defects in Tibetan language keyboard layout Tibetan (PRC) based on QWERTY keyboard, if the design philosophy of Tibetan (PRC) to be directly migrated to the Tibetan language keyboard layout design of mobile message treatment facility, then these defects can become more obvious.Therefore, need to redesign a kind of Tibetan language keyboard layout towards mobile message treatment facility and input system from brand-new angle.
Summary of the invention
According to the feature of Tibetan language word, the present invention devises a kind of Tibetan language keyboard layout based on 36 key mappings and input system, such as only distributing a key mapping for each consonant, often pair of similar letter being arranged in the same position of different keyboard, utilizing letter by adopting
the technology such as repeated code, font decomposition of elimination, the mobile message such as mobile phone, panel computer treatment facility achieves Tibetan language syllable, Brahma-sutra Tibetan letter, Tibetan language are digital, punctuation mark and conventional graphical symbol efficient, accurately input.

2. only distribute a key mapping for each consonant
The quantity of Tibetan language letter is relatively many, and each consonant has occupy-place and not occupy-place two kinds of forms, and indivedual consonant has four kinds to manifest form because there is distortion.Therefore, if all give a key mapping for each of consonant manifests form, then required key mapping sum can sharply increase, thus causes looking for the defects such as the frequent and button process of word difficulty, keyboard shift is complicated.
The present invention is that each consonant only distributes a key mapping and do not consider whether it is out of shape and whether occupy-place.Such as, letter
four kinds are had to manifest form and occupy-place is indeformable
occupy-place is out of shape
not occupy-place is indeformable
and not occupy-place distortion
but the present invention is letter
only distribute a key mapping, and no longer consider that the various of it manifest form.The present invention is to letter
and other consonant carries out similar process and is each consonant and only distributes a key mapping.
For each consonant only distributes the way of a key mapping, decrease required key mapping sum, overcome exist in existing Tibetan language keyboard layout look for the defects such as the frequent and button process of word difficulty, keyboard shift is complicated.
3. the order substring of pair syllable is encoded
Angle entered from the keyboard, the whether significant foundation of combination judging between several English alphabet is whether they form the order substring of a word.In the present invention, order substring refers to the character string of front r (r to be no more than in a word number of letter) the individual letter of a word according to their sequential write arrangements in this word, such as: the order substring of English word able is a, ab, abl, able respectively.For Tibetan language, judge the whether significant foundation of the combination of several letter is whether they form the order substring of a syllable.Such as: monogram
and
it is all syllable
order substring.
The present invention encodes to each order substring of Tibetan language syllable successively, such as: to syllable
each order substring coding after, input the input that each letter is corresponding in syllable key mapping just can realize syllable successively: (1) presses
during key, input
(2) press
during key, input
(3) press
during key, input
(4) press
during key, input
this coded system mutual restricting relation reflected between Tibetan language letter also dynamically reflects the process of Tibetan language letter composition syllable simultaneously.
4. often pair of similar letter is arranged in the same position of different keyboard
English alphabet has dividing of capital and small letter, and the lower case and upper case of same letter is distributed in the same position of Master Keyboard and the first auxiliary keyboard.Such as: the position of capitalization A on the first auxiliary keyboard is identical with the position of lowercase a on Master Keyboard.
Tibetan language letter do not have capital and small letter point, but it is similar to exist to a certain degree between some consonant: (1) letter
respectively than letter
many off beat symbols
therefore, letter
with
with
and
with
constitute 3 to similar letter; (2) letter
with
between pronunciation only have fine distinction, therefore, can by letter
with
be classified as 1 to similar letter; (3) letter
respectively with letter
symmetry, therefore, letter
with
with
with
with
and
with
form 5 to similar letter.9 are had to similar letter between such Tibetan language consonant.
The present invention is arranged in 9 in the same position of different keyboard similar consonant.Due to consonant
frequency of utilization apparently higher than their similar letter
frequency of utilization, therefore, the present invention is by consonant relatively high for frequency of utilization
be arranged in the ad-hoc location of Master Keyboard, and by their similar letter
be arranged in the same position of the first auxiliary keyboard respectively.Thisly user is facilitated to remember often pair of similar letter way be arranged in the same position of different keyboard.
5. utilize letter
eliminate repeated code
In Tibetan language input system, coincident code problem is inevitable: continuously during input two consonants, owing to can left and right combination also can combine up and down between them, select a kind of in needing user may combine at these two kinds, therefore, two kinds between consonant may be combined and constitute a pair repeated code.Such as: input successively with keyboard
with
time need user to combine from the left and right of these two consonants
combine up and down
middle selection is a kind of, like this
with
just constitute a pair repeated code.Statistics shows, has 58 pairs of repeated codes in 4631 conventional Tibetan language syllables.
The present invention utilizes letter
eliminate repeated code: directly press the key mapping that two consonants are corresponding, then input the combination up and down of these two consonants; Press first consonant, letter successively
the key mapping corresponding with second consonant, then input the left and right combination of these two consonants.Such as: directly press letter
with
the key mapping of correspondence then inputs their combination up and down
and press letter successively
with
corresponding key mapping then inputs consonant
with
left and right combination
Specify m key to eliminate repeated code specially with Tibetan (PRC) to compare, the present invention utilizes letter
the way eliminating repeated code more meets Tibetan language syntax rule and further reduces required key mapping sum.
6. pair subalphbet and symbol carry out font decomposition
Utilize Tibetan (PRC) to input whole Tibetan language character listed by National standard baseset, superset A and superset B and symbol needs 192 key mappings, too much key mapping sum causes the existing defective main cause of Tibetan (PRC).In order to input Tibetan language character as much as possible and symbol by the least possible key mapping, present invention employs font decomposition technique.A compound font is resolved into base font sequence according to its sequential write by so-called font decomposition exactly, such as, and compound vowel
be decomposed into vowel
with
combination up and down.Rules for writing and Unicode character attibute database to be met to the font decomposition of a character or symbol.The present invention mainly carries out font decomposition to compound vowel, part Brahma-sutra Tibetan consonant and part graphical symbol:
Compound vowel
be decomposed into vowel
with
combination up and down, this isolation meets vowel
rules for writing and Unicode character attibute database to the description of this vowel attribute.To compound vowel
and
similar decomposition can be carried out.The present invention to the decomposition of compound vowel in the character of sequence number 1 to 9 in table 1 and corresponding decomposition result.
Brahma-sutra Tibetan consonant
be decomposed into consonant
with
combination up and down, this isolation meets letter
rules for writing and Unicode character attibute database to the description of this alphabetical attribute.To Brahma-sutra Tibetan consonant
and
similar decomposition can be carried out.The present invention to the decomposition of compound Brahma-sutra Tibetan consonant in the character of sequence number 10 to 18 in table 1 and corresponding decomposition result.
Punctuation mark
be decomposed into two
left and right combination, this isolation meets punctuation mark
rules for writing and Unicode character attibute database to the description of this symbol attribute.Graphical symbol
graphical symbol can be resolved into
with
left and right combination, to graphical symbol
with
similar decomposition can be carried out; Graphical symbol
be decomposed into three graphical symbols
combination, right
similar decomposition can be carried out.The present invention to the decomposition of partial symbols in the character of sequence number 19 to 24 in table 1 and corresponding decomposition result.
Because the present invention only distributes key mapping to the base font after decomposition, and realize the input to compound font by these base fonts, thus decrease the sum of required key mapping greatly.
The font decomposition result of table 1 compound vowel, part Brahma-sutra Tibetan letter and partial symbols
