Description

The method of literal input on the keypad

Technical field

The present invention relates to electronic technology field, relate in particular to a kind of on keypad the method for input alphabet.

Background technology

Nowadays, keypad mainly is the requirement that it can be used for letter and number as the application of input end more and more widely, has compact conformation, and volume is little, easy to operate and convenient carrying.Such as, electronic equipments such as the numeric keypad on the computing machine, mobile phone, telepilot are all used keypad.People are more and more depending on electronicss such as mobile phone, and along with development of science and technology, it is one that electronics can collect conversation, online, note and video display amusement, has greatly made things convenient for people's life.Propelling along with technology, the function of communication apparatus such as mobile phone reaches the function of computing machine gradually, but, because electronic equipments such as mobile phone are owing to be subjected to the restriction of volume, usually the keypad on it can only have tens keys, and computing machine has more than 100 key usually, so, wanting to get literal with mobile phone apace as computing machine is not to be easy to something, need be such as English alphabet of input by twice even three keys, to import more loaded down with trivial detailsly, efficient is very low, how to find easy and the high input method of efficient is the technical matters that the industry needs to be resolved hurrily always, is that example describes below with the mobile phone:

At first, look at the layout of English alphabet on the numerical key:

Button (letter on the button)	The letter of Pai Lieing according to the order of sequence

Further comprise after the step B: utilize the selection output of literal and other literal of literal combination carrying out of described demonstration.

Further comprise after the step B: according to the described punctuation mark of array output of described numerical key and * key or # key.

Literal on the described button is English, and according to the format layout of four lines three row is: first row from top to bottom each row are followed successively by 1,4,7 and the * key; Secondary series from top to bottom each row is followed successively by 2,5,8,0 key; The 3rd row from top to bottom each row are followed successively by 3,6,9 and the # key; Described numerical key 2 corresponding abc, numerical key 3 corresponding def, numerical key 4 corresponding ghi, numerical key 5 corresponding jkl, numerical key 6 corresponding mno, numerical key 7 corresponding pqrs, numerical key 8 corresponding tuv and numerical key 9 corresponding wxyz.

Formulate the character code rule according to key combination in the steps A, be specially:

According to next column combination digital key when the numerical key at the button at described English alphabet place, prostatitis and this English alphabet place; When the numerical key at described literal place is listed as for last, make up with the first respective counts keyboard that is listed as; Wherein, the line number at the combination digital key place of described next column is the sequence valve on the numerical key of described English alphabet place; And each English alphabet is corresponding one by one with two buttons of keypad, first button is got the first English alphabet of keyboard place button, and second button satisfies two rule: a, follows first button not in same column; B, described second button place line number are determined by the sequence valve that distributes on this English alphabet place numerical key.

Character code between described button and literal is provided with table:

	??A(a)＝[2，3]＝(0，1，1) ??B(b)＝[2，6]＝(0，1，2) ??C(c)＝[2，9]＝(0，1，3)	??D(d)＝[3，1]＝(1，0，1) ??E(e)＝[3，4]＝(2，0，1) ??F(f)＝[3，7]＝(3，0，1)
			??G(g)＝[4，2]＝(2，1，0) ??H(h)＝[4，5]＝(2，2，0) ??I(i)＝[4，8]＝(2，3，0)	??J(j)＝[5，3]＝(0，2，1) ??K(k)＝[5，6]＝(0，2，2) ??L(l)＝[5，9]＝(0，2，3)	??M(m)＝[6，1]＝(1，0，2) ??N(n)＝[6，4]＝(2，0，2) ??O(o)＝[6，7]＝(3，0，2)
??P(p)＝[7，2]＝(3，1，0) ??Q(q)＝[7，5]＝(3，2，0) ??R(r)＝[7，8]＝(3，3，0) ??S(s)＝[7，0]＝(3，4，0)	??T(t)＝[8，3]＝(0，3，1) ??U(u)＝[8，6]＝(0，3，2) ??V(v)＝[8，9]＝(0，3，3)	??W(w)＝[9，1]＝(1，0，3) ??X(x)＝[9，4]＝(2，0，3) ??Y(y)＝[9，7]＝(3，0，3) ??Z(z)＝[9，*]＝(4，0，3)

Punctuation mark in the above table is corresponding with binary array and ternary array.

Described character code rule comprises that further the encoding setting table between button and punctuation mark is:

Left mouse button=[1,2]=(1,1,0) right mouse button=[1,2,3]=(1,1,1) ,=[1,5]=(1,2,0).=[1,8]=(1,3,0)?=[1,0]=(1,4,0)
			Space=[4,5,6]=(2,2,2)
			～=[*, 2]=(4,1,0) :=[*, 5]=(4,2,0); "=[*, 0]=(4,4,0) (=[*, 3]=(4,0,1))=[*, 6]=(4,0,2) ,=[*, 8]=(4,3,0)	=[0,3]=(0,4,1) ()=[0,6]=(0,4,2)/()=[0,6]=(0,4,3)	@=[#, 1]=(1,0,4) $ ($)=[#, 4]=(2,0,4) %=[#, 7]=(3,0,4) ^ (... )=[#, 2]=(0,1,4) ﹠amp;=[#, 5]=(0,2,4) _=[#, 8]=(0,3,4)-=[#, 0]=(0,4,4)

Punctuation mark in the above table is corresponding with binary array and ternary array.

Step B is described to show that according to the default corresponding compiler algorithm of key combination rule execution the corresponding letter or the process of punctuation mark are:

B1, according to the one-to-one relationship between letter and the numerical key, with each the letter represent with a binary array [m, n] and ternary array (A (1), A (2), A (3)); Wherein, the combination of described binary array representation numerical key (or */# key) m and numerical key (or */# key) n; And ternary array (A (1), A (2), A (3)) is represented this three key combination that lists, described ternary array (A (1), A (2), A (3)) in the span of j component be 0,1,2,3,4}, (j=1,2,3) represent that promptly j lists the i line unit, the no button of 0 expression.

B2, when pressing described two combination buttons simultaneously, show corresponding English alphabet according to the character code rule; Wherein, when pressing two buttons simultaneously, realize Macintosh and built-up sequence by assignment algorithm to described binary array and ternary array.

Step B2 is described further to be comprised the assignment algorithm of binary array and ternary array as mentioned above:

B21, the i line unit that j lists in described ternary array are pressed, assignment A (j)=i then, B (j)=0; The i line unit that j lists is released, assignment B (j)=i, and assignment A (j) remains unchanged;

B22, when described button and release key are operated, all judge that according to the simultaneity algorithm output that described ternary array is carried out literal or punctuation mark according to the array end value of the described button of operation and sequence valve coding schedule between literal and the coding schedule between button and punctuation mark shows.

B23, at the described simultaneity algorithm of step B22, as (B (1), B (2), B (3))=(A (1), A (2), A (3)), then according to coding schedule, the character of output (A (1), A (2), A (3)) representative, and two groups of arrays are made zero.When two groups of arrays do not wait, then wouldn't export, only do some screen prompts.

Described * key and # key are the switch combination key of capital and small letter English alphabet, and each capitalization and its corresponding lowercase be corresponding to be defined as an identical described numerical key.

The technique effect that the present invention reaches is as follows: character input method of the present invention can be widely used in mobile phone, on telepilot and the mouse, is easy to learn and use.Character input method of the present invention does not need memory, only need press other button simultaneously according to the order of character code rule, just can import a letter.Continuous button drawback repeatedly when having replaced on the present keypad input characters, high input speed is saved time, and raises the efficiency.

Embodiment

The method of input alphabet on the keypad of the present invention is pressed four lines three column format layouts with the button and the literal on the button of described keypad, and described keypad comprises ten key; It is characterized in that this method comprises:

A, be logical foundations, formulate the character code rule according to key combination with the format layout of described button, and each literal on the described button is corresponding one by one with two combination buttons of described keypad;

B, when pressing two buttons arbitrarily according to default character code rule, then carry out corresponding compiler algorithm and show corresponding character or punctuation mark.

Below we are that example describes with keyboard and English on existing mobile phone/phone, please refer to the layout table of English alphabet on the button key in the background technology.Certainly, keypad distribution text type and layout have a variety of, such as Korean, Japanese or the like, because coding rule is identical with mode, needn't give unnecessary details the situation of other literal and distributed layout at this.

Present embodiment is only considered 0～9 key (10 altogether) of smart mobile phone, gets 26 letters if press two keys with two fingers.If do not consider the sequencing of two key combinations, 10 total C of numerical key ² ₁₀=45 kinds of array modes, being used for importing 26 letters has been more than sufficient.Two for convenience finger operations and people easily remember input method rule of the present invention, only the button between the row are made up to get final product.Because modular keypad is divided into four lines three row, the mode of the next column combination digital key of the numerical key of stipulating alphabetical place according to encoding and the numerical key at alphabetical place.Certainly, the branch about the order of combination does not have, from left to right and from right to left mode makes up all passable.With order from left to right is example, and first row and secondary series, secondary series and tertial numerical key make up, because the 3rd classify last row as, carry out the array output letter respectively so the 3rd row and first are listed as.For example, the key at letter " a " place is the numerical key " 2 " in the secondary series, so during two finger button, first refers to button " 2 ", again because " a " is arranged in first of its place key lexicographic order, because the combination digital key of next column is that serial number on the numerical key of alphabetical place is determined by line number.The second then corresponding with it finger button is exactly several from top to bottom first line units in the 3rd row, i.e. numerical key " 3 ".Stipulate like this by us, when two fingers while buttons 2 and key 3, be output as letter " a ".

Determine the letter that will import, press that second on the pairing next column of this lexicographic order refers to button on the numerical key at this alphabetical place and this key, for example, " 2 " and " 3 " key is pressed in input " a " simultaneously, then exports " a "; For another example, input " s ", then two fingers are pressed " 7 " and " 0 " key simultaneously.(because the key at " s " place is the numerical key " 7 " in first row, and be that order is the 4th letter, therefore first refers to (left side refers to) by " 7 " key, and second finger (right side refers to) is pressed " 0 " key in the secondary series).Specify the input of letter " z " in addition, because " z " order of letter in numerical key is the 4th, but have only three numerical keys among first row, so second digital that we stipulate and " z " is corresponding is numerical key 9 and * key.

Encoding scheme:

Ten key: its input is single the indication and hits this numerical key;

26 English alphabets: represent that by two finger button gained (its encoding scheme is chart as follows) first digit first refers to button, second digit represents that second refers to button.

First refers to coded digital, is the numeral on should letter place button in the mobile phones universal panel;

Second refers to coded digital, gets this letter Ser.No. that letter is arranged in the universal surface plate button earlier, and second refers to that coded digital is the numerical key at this pairing capable place of ordinal number from top to bottom (annotate: tertial next column is first row) of next column;

Capitalization is to import gained in the capitalization state, and the opening and closing of capitalization state use Macintosh to be: press " * " and " # " key simultaneously.

Have the mode of 26 kinds of combination digital keys in the following table,

	??A(a)＝[2，3]＝(0，1，1) ??B(b)＝[2，6]＝(0，1，2) ??C(c)＝[2，9]＝(0，1，3)	??D(d)＝[3，1]＝(1，0，1) ??E(e)＝[3，4]＝(2，0，1) ??F(f)＝[3，7]＝(3，0，1)
			??G(g)＝[4，2]＝(2，1，0) ??H(h)＝[4，5]＝(2，2，0) ??I(i)＝[4，8]＝(2，3，0)	??J(j)＝[5，3]＝(0，2，1) ??K(k)＝[5，6]＝(0，2，2) ??L(l)＝[5，9]＝(0，2，3)	??M(m)＝[6，1]＝(1，0，2) ??N(n)＝[6，4]＝(2，0，2) ??O(o)＝[6，7]＝(3，0，2)
??P(p)＝[7，2]＝(3，1，0) ??Q(q)＝[7，5]＝(3，2，0) ??R(r)＝[7，8]＝(3，3，0) ??S(s)＝[7，0]＝(3，4，0)	??T(t)＝[8，3]＝(0，3，1) ??U(u)＝[8，6]＝(0，3，2) ??V(v)＝[8，9]＝(0，3，3)	??W(w)＝[9，1]＝(1，0，3) ??X(x)＝[9，4]＝(2，0，3) ??Y(y)＝[9，7]＝(3，0，3) ??Z(z)＝[9，*]＝(4，0，3)

Binary array and ternary array in the instruction card more below:

Because according to behind the top alphabet code, " 1 " key, " * " and " # " do not have corresponding English alphabet, and we can add punctuate commonly used and symbol, as ", ", "." or the like.

Because " 1 ", " * " and " # " key have 3 kinds of array modes, add the combination C of the key between the numerical key row of English alphabet place ² ₁₀=45 kinds, have 48 kinds of combinations.Remove the combination of " * " and " # " key of the combination of 26 out alphabets and capital and small letter conversion, we can also 21 kinds of punctuates of layout and the combination of symbol.

For clarity sake, on show us and adopt nine palace lattice, the position of letter and nine palace lattice concerns on the existing mobile phone faceplate to keep.Two arrays on this letter the right are promptly represented the one-to-one relationship between this letter and two numerical keys.The wherein combination of binary array [m, n] expression numerical key (or #/* key) m and numerical key (or #/* key) n, the span of j component is { 0 in the ternary array (A (1), A (2), A (3)), 1,2,3,4}, (j=1,2,3), represent that promptly j lists the i line unit, the no button of 0 expression.Be used for equally only representing the definition key position, to make things convenient for the algorithm of our back with the ranks position.

Press described two combination buttons when simultaneously, show pairing English alphabet according to the character code rule.Note the requirement of button simultaneously, show the combination out-of-order relation of two numerical keys, promptly encoding coordinate [2,3] is all represented same alphabetical a with encoding coordinate [3,2].

The implication of here " button simultaneously " is defined as an algorithm, and narration algorithm necessity is with as follows by setting parameter definition rationality earlier:

When two keys or three key combinations, always might occur a key earlier by behind, the key by or a key discharges earlier, situation about discharging behind another key, so need algorithm to solve how to define this simultaneity, guarantee correct output.

Setup parameter array A (j), j=1,2,3, j represents the j row here, the assignment scope of A (j) is { 0,1,2,3,4}, expression respectively, the i line unit that lists as j is pressed, then assignment A (j)=i, i=1,2,3,4,0 value representation j row do not have key to press, i.e. assignment A (j)=0.Same setup parameter array, B (j), j=1,2,3, j represents the j row, the assignment scope of B (j) is { 0,1,2,3,4}, expression respectively, the i line unit that lists as j is released, assignment B (j)=i, i=1,2,3,4,0 value representation j row do not have key to discharge, i.e. assignment B (j)=0.We directly are designated as it ternary array (A (1), A (2), A (3)), (B (1), B (2), B (3)) later on.

The definition of this assignment is reasonably because according to our combination button rule, in the same row, at most can only be by next key, this is parameter array A (j), the assignment of B (j), by unique being defined as 0,1,2,3, the number among the 4}.This rule meets the key switch matrix structure of four lines three row 12 key boards simultaneously, can not produce the Macintosh that the key switch matrix structure does not realize.

By assignment algorithm, realize our Macintosh output function to these two arrays.It is as follows now to state algorithm:

The i line unit that lists as j is pressed, assignment A (j)=i then, B (j)=0;

The i line unit that lists as j is released, assignment B (j)=i, and assignment A (j) remains unchanged;

When the operation of button and release key, all judge and carry out:

(if B (1), B (2), B (3))=(A (1), A (2), A (3)), then according to coding schedule, output

The character of (A (1), A (2), A (3)) representative, and assignment makes zero.

(A(1)，A(2)，A(3))：＝(B(1)，B(2)，B(3))：＝(0，0，0)。

(if B (1), B (2), B (3)) ≠ (A (1), A (2), A (3)), regulation only showed, pointed out (A (1), A (2) on screen this moment, A (3)) corresponding character, but finally do not confirm this output, now be exemplified below, for example combination button, one refers to pin the 2nd, and to be listed as the 1st line unit motionless, and one refers to pin the 3rd, and to be listed as the 1st line unit motionless, at this moment (A (1), A (2), A (3)) :=(0,1,1), (B (1), B (2), B (3)) :=(0,0,0)

Can show (A (1), A (2), A (3)) coding corresponding characters " a " on the screen, but finally not confirm this output.If this moment, keeping pinning the 2nd, to be listed as the 1st line unit motionless, is listed as the 1st row button with the 3rd and discharges, (A (1), A (2), A (3))=(0,1,1) at this moment, (B (1), B (2), B (3)) :=(0,0,1).

Still show original character " a " on the screen, but still and final output unconfirmed.Continue now to keep the 2nd to be listed as the 1st line unit and to pin motionlessly, press the 3rd and be listed as the 2nd line unit, at this moment,

(A(1)，A(2)，A(3))＝(0，1，2)，(B(1)，B(2)，B(3))：＝(0，0，0)，

Then on the screen with original character display " a " cancellation, and replace the character " b " of demonstration (A (1), A (2), A (3)) expression.Now when two refer to discharge simultaneously, though have have earlier after, be listed as the 2nd line unit such as release the 3rd earlier, at this moment

(A(1)，A(2)，A(3))＝(0，1，2)，(B(1)，B(2)，B(3))：＝(0，0，2)

Screen keeps character display " b ", but final as yet affirmation output.Discharge the 2nd more at last and be listed as the 1st line unit, at this moment

(A(1)，A(2)，A(3))＝(0，1，2)，(B(1)，B(2)，B(3))：＝(0，1，2)

According to algorithm, finally confirm the corresponding character " b " of output encoder.

Our Macintosh algorithm is different from traditional Windows Macintosh algorithm, just with our algorithm difference, press C after press Ctrl earlier as the Macintosh characteristics of Ctrl+C, and is just different fully with the effect of pressing Ctrl after the C key is pressed by elder generation.And according to our algorithm, the Macintosh output effect is with successively the button order is irrelevant.

2 for.Be conventional sign, for example the Nokia mobile phone is placed on them on " 1 " key.We still continue to use this tradition.For example, we can stipulate following input rule:

Left mouse button=[1,2]=(1,1,0) right mouse button=[1,2,3]=(1,1,1) ,=[1,5]=(1,2,0).=[1,8]=(1,3,0)?=[1,0]=(1,4,0)
			Space=[4,5,6]=(2,2,2)
			～=[*, 2]=(4,1,0) :=[*, 5]=(4,2,0); "=[*, 0]=(4,4,0) (=[*, 3]=(4,0,1))=[*, 6]=(4,0,2) ,=[*, 8]=(4,3,0)	=[0,3]=(0,4,1) ()=[0,6]=(0,4,2)/()=[0,6]=(0,4,3)	@=[#, 1]=(1,0,4) $ ($)=[#, 4]=(2,0,4) %=[#, 7]=(3,0,4) ^ (... )=[#, 2]=(0,1,4) ﹠amp;=[#, 5]=(0,2,4) _=[#, 8]=(0,3,4)-=[#, 0]=(0,4,4)

Totally 21 kinds of combinations more than [notes] (in the bracket is expression after the Chinese and English conversion)

Two, combining of input method of the present invention and tradition Chinese character input method:

The method of input alphabet of the present invention only is controlled at the array mode that refers to buttons with two, so with former any keyboard-coding that singly refers to, contradiction not.Show selection input method scheme as " # " key table in the T9 button, " * " key table shows the selection punctuation mark, still can use as usual.Simultaneously, increase after the input method of the present invention, its output character can directly apply to these input method of Chinese character, no matter which kind of encoding scheme it is, based on phonetic or stroke.

So the present invention refers to that with two the method for input alphabets do not repel traditional input method, predictive input mode especially, their relation in fact is a joining relation, promptly gets character with two finger input methods earlier, re-uses the various full keyboard input method schemes on the computing machine.Compare with the traditional predictive input mode on 12 key mobile phones, the latter is based upon 9-12 key list and refers in the input, so can only be in fact to associate by the combination of numerical key, and a completely specified letter is got in two finger input rules two finger blow earlier, again association is based upon in the combination of letter, has so just directly reached the efficient of full keyboard Chinese characters association input method on the computing machine.

Three, the range of application of input method of the present invention and meaning

Input method of the present invention can be applied in mobile phone, on telepilot and the mouse, is easy to learn and use, and its meaning is summarized as follows:

1, the hommization that is easy to learn and use: its 26 alphabetic coding schemes, unlike the Five-stroke Method scheme, need remember a lot of rules, we are as long as a cryptoprinciple, use this logic, seeing 12 key universal surface plates on the mobile phone, without any need for memory, just can get 26 letters and punctuate commonly used, symbol.Simultaneously, input method of the present invention also can refer to encode and point out the two finger codings and three of punctuation mark, when singly referring to pin " * " key, punctuate menu and coding prompting promptly can appear, this moment or use traditional selection mode one by one to get punctuate, perhaps after seeing the coding prompting, refer to get punctuate by this with two fingers or three again.For individual subscriber punctuate, symbol commonly used, nature can be remembered very soon like this.

2, compare with the predictive input mode on the smart mobile phone, what get with input method of the present invention earlier is letter, and then on the basis of phonetic letter, any one computer input method for Chinese character that the linking user likes.This presses numerical key with the letter in the brain than the user in existing mobile phone operation, make up association by numerical key and produce correct monogram, and the interface is hommization more, and the efficient of association also can promote greatly.

3, application on the telepilot and meaning thereof: the operation tool of home entertainment center is exactly a telepilot, can control the computer in TV, air-conditioning, home entertainment center and parlor etc. with this.Telepilot encoding scheme in the past can only be utilized its numerical key and several basic operating key, input method of the present invention if can be introduced wherein, and the function of telepilot input information can significantly strengthen.

4, the application on the keypad mouse: we can be applied to input method of the present invention on the keypad mouse.The keypad mouse promptly is that 12 key keypads are installed on the mouse.Its meaning and efficient is,

A) along with the rise of the Internet culture, the online friend is divided into two kinds, mouse family and keyboard family, and the former mouse frequency of utilization is higher, and the latter then is that the keyboard frequency of utilization is higher.Use input method of the present invention and keypad mouse, then this biculturalism can be unified.Make and go up net operation (input the user name password, fill in list), smooth more nature.

B) refer to input methods for operating two on computers, when we reach identical full key board disc type input efficiency, in fact only used a hand and on keypad, imported.Therefore freed an other hand, if two hands can use two keypad mouses simultaneously, then input efficiency can be higher.Left hand and right hand is respectively with a keypad mouse, and every hand is accused three row of system keypads with the third finger, middle finger, forefinger three.Like this, a unit is in input time, and both hands use two to refer to input method, can squeeze into two characters simultaneously.Anyone uses this input method, and its input speed must be in the past two times.During such as use Two bors d's oeuveres input method of Chinese character, both hands two refer to input methods, just in time once import two characters (consonant character and rhythm alphabetic character), become a Two bors d's oeuveres.Therefore, with the hands two refer to input method, and in conjunction with the input of Two bors d's oeuveres Chinese character, typing speed can meet or exceed the speed that word read in voice.Encoding scheme on the computer small keyboard now is described:

Because the arrangement of computer small keyboard, different with mobile phone, in addition, numerical key on the computing machine arrange just in time with mobile phone on opposite, a kind of is with the character position on its nine numerical keys of 3 * 3, still according to mobile phones universal panel (1-9 key) orientation format permutation, input method is with just the same in the past.This mainly is the feel when considering touch system, keeps consistent with mobile phone.

As shown in Figure 1, be the numerical key part (letter in the keyboard is the imagination signal, with convenient coding) of keypad, coding rule is:
