Description KEYBOARD FOR THE MOBILE TERMINAL
Technical Field
[1] The present invention relates to a keyboard for a mobile terminal, and more particularly, to a keyboard for a mobile terminal, in which a fifteen (3x5) key structure is formed by adding three keys to a general twelve (3x4) key structure of the mobile terminal, wherein two left columns are used as a consonant unit and one right column is used as a vowel unit in case of a vertical type keyboard, and three left columns are used as a consonant unit and two right columns are used as a vowel unit in case of a horizontal type keyboard, whereby characters can be easily input and the number of keystrokes can be reduced, so that the keyboard can be used fast and conveniently. Background Art
[2] Recently, a wireless mobile communication apparatus such as a cellular phone has been widely used. Besides a call making or receiving function regarded as an intrinsic function of a mobile terminal, a supplementary function for sending or receiving a message has been added to the mobile terminal, which makes the user frequently input characters. Accordingly, various methods for inputting characters using the mobile terminal have been suggested.
[3] In the general mobile terminal such as a cellular phone or PDA, a keyboard consists of twelve (3x4) keys. The respective keys are combined to form characters.
[4] Hereinafter, a general keyboard for a mobile terminal will be explained with reference to the accompanying drawing.
[5] Fig. 1 illustrates one example of key arrangement of a conventional mobile terminal using the Chunjiin system.
[6] In the key arrangement using the Chunjiin system, all vowels can be generated by using three keys 'D', 'D' and 'D'. Referring to Fig. 1, a vowel unit 10 for generating vowels and a consonant unit 20 for generating consonants are disposed at the upper and lower portions of the keyboard, respectively.
[7] In the consonant unit 20, the consonants generated through one keystroke are 'D', 'D',
'D', 'D', 'D', 'D' and 'D', the consonants generated through two keystrokes are 'D', 'D', 'D', 'D', 'D', 'D' and 'D', and the consonants generated through three keystrokes are 'D', 'D', 'D', 'D' and 'D'. In the vowel unit 10, all the vowels can be generated by combining the three vowels 'D', 'D' and 'D' which are the basic vowels of the Chunjiin system.
[8] For example, when 'D' and 'D' are sequentially pressed, 'D' is generated, and when 'D' is additionally pressed, 'D' is generated. In addition, 'D' can be generated by consecutively pressing 'D' twice and then 'D' twice. Meanwhile, fortes such as 'D' and 'D' can be generated
by consecutively pressing 'D' and 'D' three times, respectively.
[9] However, in the above key arrangement, all the vowels except 'D' and 'D' require at least two keystrokes. Therefore, the number of the keystrokes is increased in the vowel generation, thereby reducing the character input speed. Moreover, the vowels and the consonants are disposed not at the right and left sides but at the upper and lower portions, respectively. Thus, there is a disadvantage in that this key arrangement complicates character input as compared with the key arrangement in which the consonants are disposed at the left side and the vowels are disposed at the right side.
[10] Fig. 2 illustrates one example of key arrangement of a conventional mobile terminal using the Naramal system based on the creation principle of the Hunminjeongeum.
[11] As illustrated in Fig. 2, in the key arrangement using the Naramal system, six consonants and six vowels of highest frequency of use are placed on nine keys of the mobile terminal so as to support consecutive character input. This keyboard includes a consonant unit 30 for generating basic consonants, a double consonant unit 60 for generating double consonants in combination with the consonant unit 30, a vowel unit 40 for generating vowels, and a stroke adding unit 50 for generating stroke-added consonants or stroke-added vowels in combination with the consonant unit 30 and the vowel unit 40, to thereby generate all characters.
[12] In the consonant unit 30, the consonants generated through one keystroke are 'D', 'D',
'D', 'D', 'D' and 'D', and the consonants generated through two keystrokes are 'D', 'D', 'D', 'D' and 'D' input by the combinations of the corresponding keys of the consonant unit 30 and the stroke adding unit 50, and 'D' and 'D' input by the combinations of the corresponding keys of the consonant unit 30 and the double consonant unit 60. In addition, the consonants generated through three keystrokes are 'D', 'D' and 'D' input by the combinations of the consonant unit 30 and the stroke adding unit 50, and double consonants such as 'D', 'D' and 'D' input by the combinations of the consonant unit 30, the stroke adding unit 50 and the double consonant unit 60.
[13] For example, 'D' is generated through two keystrokes by sequentially pressing key 7 of the consonant unit 30 and the stroke adding unit 50, 'D' is generated through three keystrokes by pressing key 5 of the consonant unit 30 and consecutively pressing the stroke adding unit 50 twice, and 'D' is generated through three keystrokes by sequentially pressing key 2 of the consonant unit 30, the stroke adding unit 50 and the double consonant unit 60.
[14] In the vowel unit 40, the basic vowels such as 'D', 'D', 'D', 'D', 'D' and 'D' are generated through one keystroke or two consecutive keystrokes. The stroke-added vowels such as 'D', 'D', 'D', 'D', 'D', 'D', 'D', 'D' and 'D' are generated through the combinations of the vowel unit 40 and the stroke adding unit 50.
[15] In the above conventional key arrangement, the keys are scientifically arranged for
character input, i.e., the consonants are disposed at the left side and the vowels are disposed at the right side. However, all the consonants except the six consonants of the consonant unit 30 require at least two keystrokes, and all the vowels except the four vowels also require at least two keystrokes. As compared with the Chunjiin system of Fig. 1, the number of the keystrokes is generally increased. That is, even the simple consonants such as 'D', 'D', 'D' and 'D' and the simple vowels such as 'D', 'D', 'D', 'D' are generated in combination with the stroke adding unit 50. As a result, there are disadvantage in that the character input speed is lowered and the complicated character input system should be thoroughly known.
[16] As such, the Chunjiin and Naramal systems, which have been widely used, suggest their own character input systems with respective advantages. However, they have a limitation in the scientific key arrangement or the minimization of the keystrokes. Disclosure of Invention Technical Problem

[93] Figs. 13 and 14 are block diagrams illustrating Spanish keyboards for mobile terminals according to the present invention.
[94] As in the English keyboard of Fig. 7, a Spanish keyboard for a mobile terminal is formed as a vertical or horizontal type keyboard with fifteen (3x5) keys. A consonant unit 500 consisting of ten keys is disposed at the left side of the keyboard, a vowel unit 520 consisting of five keys is disposed at the right side of the keyboard, and a capital/ small letter conversion unit 540 consisting of one key is disposed at the right top end of the keyboard.
[95] The configuration of the Spanish keyboard is similar to that of the English keyboard of Fig. 7.
[96] That is, as shown in Fig. 13, in the vertical type keyboard, 'B/C and 'D/F' of the consonant unit 500 are placed on the first and second columns of the first row, 'A' of the vowel unit 520 is placed on the third column of the first row, 'G/Ff and 'J/K' of the consonant unit 500 are placed on the first and second columns of the second row, 'E' of the vowel unit 520 is placed on the third column of the second row, 'L/M/LL' and 'N/ P/N' of the consonant unit 500 are placed on the first and second columns of the third row, T of the vowel unit 520 is placed on the third column of the third row, 'R/S' and 'T/V of the consonant unit 500 are placed on the first and second columns of the fourth row, 'O' of the vowel unit 520 is placed on the third column of the fourth row, 'W/X' and 'Y/Z/Q' of the consonant unit 500 are placed on the first and second columns of the fifth row, and 'U' of the vowel unit 520 is placed on the third column of the fifth row.

[97] As depicted in Fig. 14, in the horizontal type keyboard, 'B/C, 'D/F' and 'G/Ff of the consonant unit 500 are placed on the first, second and third columns of the first row, 'A' and 'E' of the vowel unit 520 are placed on the fourth and fifth columns of the first row, 'J/K', 'L/M/LL' and 'N/P/N' of the consonant unit 500 are placed on the first, second and third columns of the second row, T and 'O' of the vowel unit 520 are placed on the fourth and fifth columns of the second row, 'R/S', 'T/V, 'W/X' and 'Y/Z/Q' of the consonant unit 500 are placed on the first, second, third and fourth columns of the third row, and 'U' of the vowel unit 520 is placed on the fifth column of the third row. There is provided the capital/small letter conversion unit 540 consisting of one key disposed at the right top end of the keyboard.
[98] However, the Spanish keyboard is different from the English keyboard of Fig. 7 in that 'LL' on the first column of the third row and 'N' on the second column of the third row can be input through three keystrokes by consecutively pressing the corresponding
key of the consonant unit.
[99] Figs. 15 and 16 are block diagrams illustrating Japanese keyboards for mobile terminals according to the present invention.
[100] A Japanese keyboard for a mobile terminal in accordance with the present invention includes fifteen (3x5) keys. A consonant unit 600 consisting of seven keys is disposed at the left side of the keyboard, a vowel unit 620 consisting of five keys is disposed at the right side of the keyboard, a contracted sound unit 640 consisting of three keys is disposed at the bottom end of the keyboard, and a partially voiced sound/voiced sound/ small sound conversion unit 660 consisting of one key is disposed at the right top end of the keyboard.
[101] Referring to Fig. 15, in a vertical type keyboard, 'fo v and ' $ ' of the consonant unit
600 are placed on the first and second columns of the first row, '<■£>' of the vowel unit 620 is placed on the third column of the first row, 'Tz' and ' ^' of the consonant unit 600 are placed on the first and second columns of the second row, 'V ^ ' of the vowel unit 620 is placed on the third column of the second row, ' Ii ' and ' ^. ' of the consonant unit 600 are placed on the first and second columns of the third row, "7 ' of the vowel unit 620 is placed on the third column of the third row, ' <o ' of the consonant unit 600 is placed on the first column of the fourth row, 't)/^?' of the contracted sound unit 640 is placed on the second column of the fourth row, ';£.' of the vowel unit 620 is placed on the third column of the fourth row, 'hi Jc ' and '^/iφ' of the contracted sound unit 640 are placed on the first and second columns of the fifth row, and ' $3 ' of the vowel unit 620 is placed on the third column of the fifth row.
[102] As illustrated in Fig. 16, in a horizontal type keyboard, 'fo v , ' $ ' and 'Tz' of the consonant unit 600 are placed on the first, second and third columns of the first row, 'X.' and '<$->' of the vowel unit 620 are placed on the fourth and fifth columns of the first row, '&', Hi' and 1 ^.' of the consonant unit 600 are placed on the first, second and third columns of the second row, '$3 ' and 'IV of the vowel unit 620 are placed on the fourth and fifth columns of the second row, ' <o ' of the consonant unit 600 is placed on the first column of the third row, 'hi Jc ', '^/iφ' and 't)/^?' of the contracted sound unit 640 are placed on the second, third and fourth columns of the third row, and "7 ' of the vowel unit 620 is placed on the fifth column of the third row.
[103] The consonants generated through one keystroke are 'fo v , ' $ ', 'Tz', '%£', Hi', 1 ^.' and
' <o ', and the consonants generated through two keystrokes by consecutively pressing the corresponding keys of the vowel unit 620 and the consonant unit 600 twice are ' % ',
1 H 1 , '<&', '£?', '&>', %', ' *) ', 'h \ 'frr and ' h '. There are partially voiced sounds and voiced sounds, such as '&*', '§ " ', ' < * ', Hf ', 1 CT 1 , ' £ ' \ ' C ', "f\ ' ■ £', 'ψ', 'Tz', "£', 'o', 1 T 1 , ' £', 'IX', Hi', 'W, 'W, 'ir, 'i;', -* 1 , 1 ^', 'IS' and 'IS', generated by consecutively
pressing the corresponding keys of the consonant unit 600 and the partially voiced sound/voiced sound/small sound conversion unit 660.
[104] For example, by consecutively pressing the vowel unit 620 and the consonant unit
600 twice, ' i§ ' can be generated by combining ' fr' on the first column of the first row with 'IV on the third column of the first row, ' (. ' can be generated by combining 'fo v on the first column of the first row with "7 ' on the third column of the second row, 'lή ~ ' can be generated by combining 'fo v on the first column of the first row with ';£.' on the third column of the third row, and ' C ' can be generated by combining' fo v on the first column of the first row with ' jo ' on the third column of the fourth row.
[105] In the same manner, ' L' can be generated by combining ' $ ' with 'VV 5 '^ " ' can be generated by combining ' $ ' with "7 ', 'it' can be generated by combining ' $ ' with 'X.', ' ϊr ' can be generated by combining ' $ ' with ' $3 ', '%' can be generated by combining 'fz' with 'VV 5 O' can be generated by combining 'fz' with "7 ', 'T' can be generated by combining 'Tz' with 'z_', and ' <h ' can be generated by combining 'Tz' with
'*?'
[106] A conventional Japanese keyboard requires two or more keystrokes in order to input ' ~ &, ^' or 'f), ~ $£, λ/. However, the Japanese keyboard of the present invention has the advantage that only one keystroke makes it possible to input 't£, ^' or 't), ~ $t, λ/.
[107] Fig. 17 is a table showing the number of the keystrokes of the consonant keys in the conventional mobile terminals and the mobile terminal of the present invention.
[108] The number of the keystrokes of the consonant keys in each system will now be compared with reference to this table. In case of compound consonants needing two or more keystrokes, the Naramal system requires keystrokes more than the Chunjiin system. In case of basic consonants, the two systems need similar keystrokes. On the contrary, the number of the keystrokes in the keyboard according to the present invention is considerably different in the compound consonants as well as the basic consonants. Thus, as compared with the Chunjiin and Naramal systems, the present invention reduces the number of the keystrokes by about 20 to 24%.
[109] Fig. 18 is a table showing the number of the keystrokes of the vowel keys in the conventional mobile terminals and the mobile terminal of the present invention.
[110] The number of the keystrokes of the vowel keys in each system will now be compared with reference to this table. The Chunjiin system has an advantageous in that only three keys are used for the input. However, the Chunjiin system requires keystrokes more than the Naramal system both in the basic and compound vowels.
[I l l] On the contrary, as compared with the Chunjiin and Naramal systems, the keyboard of the present invention remarkably reduces the number of the keystrokes. The present invention reduces the number of the keystrokes by about 25% as compared with the
Naramal system and by about 35% as compared with the Chunjiin system.
[112] Referring to the figures, in order to input consonants of Korean or English, the vertical type keyboard according to the present invention comprises the consonant unit on the two left columns or so and the vowel unit on the one right column or so, while the horizontal type keyboard comprises the consonant unit on the three left columns or so and the vowel unit on the two right columns or so. Thus, the keyboard can be configured to allow the user to use the thumbs of both the hands at the same time, thereby making the effective input possible in speed and the number of keystrokes.
[113] For example, in order to input a Korean phrase 'DDDD DD DD', the Chunjiin system needs
5+6+4+3+3+6+4+4=35 keystrokes, and the Naramal system needs 4+5+5+3+4+5+4+6=36 keystrokes. On the contrary, the keyboard according to the present invention requires 4+4+3+3+3+4+3+3=27 keystrokes only, whereby it can be noticed that the keyboard of the present invention is more effective.
[114] In addition, in order to input an English phrase 'Efficient Input Method', the
Chunjiin or Naramal system needs 41 keystrokes, but the keyboard according to the present invention needs only 26 keystrokes thus to be more effective. In case of Japanese, in order to input a phrase ' jo Ii Jc 1 CT $\ ^ ^. ~ $ ~ \ a conventional Japanese keyboard for a mobile terminal requires 26 keystrokes, but the keyboard according to the present invention requires only 14 keystrokes, whereby it can be noticed that the keyboard of the present invention is more effective.
[115] As discussed above, in the key arrangement of the present invention, the consonants can be input through maximum two keystrokes and the vowels can be input through maximum three keystrokes. Thus, as compared with the Chunjiin or Naramal system, the keyboard of the present invention has the advantage that the number of the keystrokes is considerably reduced.
[116] In addition, according to a structural aspect regarding the character input, the consonants are arranged at the left side and the vowels are arranged at the right side, so that the characters can be input by the left and right hands at the same time. As a result, the keyboard of the present invention causes characters to be easily input and the number of the keystrokes to be reduced, so that the keyboard can be used fast and conveniently.
[117] Although the present invention is described in terms of the preferred embodiments, the scope of the present invention is not limited to the specified embodiments but is defined by the appended claims. It will be apparent that those skilled in the art can make various modifications and changes thereto within the scope of the invention defined by the claims. Industrial Applicability
[118] According to the present invention, there is provided a keyboard for a mobile terminal, in which Korean characters are input by the left and right hands at the same time, whereby the characters can be easily input and the number of keystrokes can be reduced, so that the keyboard can be used fast and conveniently.
[119] Furthermore, the keyboard according to the present invention can be applied to
English, Chinese, German, French, Spanish and Japanese as well as Korean and thus universally applied to mobile terminals for every country worldwide.
