- the dual input apparatuses have the first key selection unit 100 and the second key selection unit 200.
- the first and second key selection units 100 and 200 are displayed on a display since keys of the key selection units 100 and 200 may be differently defined. For instance, when the first and second key selection units 100 and 200 are switched from an English alphabet mode to a Hangeul mode, i.e., Korean alphabet mode, the key selection units 100 and 200 need to be assigned consonants and vowels of Hangeul. However, since the physical key selection units 100 and 200 cannot be changed to have the Hangeul mode, the key selection units 100 and 200 are displayed on a display so that the key selection units 100 and 200 can be changed to have the Hangeul mode on the display.
- a Hangeul mode i.e., Korean alphabet mode
- the first and second key selection units 100 and 200 are displayed on a display.
- the key selection units 100 and 200 do not exist physically but in software, it is possible to make more compact key selection units 100 and 200.
- the user can select keys through the key selection units 100 and 200 displayed on the display.
- input means such as touch screen, remote control, mouse, and joystick, can be used to input keys.

- Fig. 7 illustrates a separated remote control which includes key selection parts each having the same 5-by-3 array as that of the first and second key selection units 100 and 200. In this case, the key selection parts are separately provided in the separated remote control.
- the key processing unit 300 analyzes and processes a key selected by the first or second key selection unit 100 or 200. For instance, the key processing unit 300 displays on a display a character corresponding to a key selected by the first or second key selection unit 100 or 200 in a text mode, or displays on the display the Explorer corresponding to a key selected by the first or second key selection unit 100 or 200 in a keyboard mode. The key processing unit 300 may redefine the keys according to the selected key.
- Fig. 8 illustrates first and second key selection units 100 and 200 each having a
- Fig. 8 illustrates a key array in a text mode, in which English alphabets are assigned to at least some of the first and second key selection units 100 and 200.
- the text mode typically supports characters inputted in portable terminals.
- the same 3-by-3 array of English alphabets is initially assigned to at least some of keys of the first and second key selection units 100 and 200. Although randomly assigned, the alphabets are preferably assigned to the 3-by-3 array of nine keys as shown in Fig. 8 so that the user can input characters conveniently and quickly.
- the English alphabet array shown in Fig. 8 is set by considering the QWERTY array and the usage frequency of English alphabets.
- the QWERTYT array has a first group consisting of English alphabets inputted with a left hand, and a second group consisting of English alphabets inputted with a right hand.
- the English alphabets are divided into a first character set, a second character set, and a third character set according to the usage frequency, and a plurality of English alphabets assigned adjacent keys in the QWERTY array are assigned to the same key or adjacent keys.
- the first character set includes English alphabets consisting of "a”, "e”,
- the second character set includes English alphabets consisting of "c", “d”, “f”, “g”, “1", “m”, “p”, “u", and "w”
- the third character set includes English alphabets consisting of "b”, “j”, “k”, “q”, "v", "x", "y”, and "z”.
- the respective character sets may have usage frequencies different from actual usage frequencies to make an array similar to the QWERTY array. For example, even though “y” has a usage frequency a little higher than “p”, “y” belongs to the third character set and "p" belongs to the second character set.
- the Separator ([sep]) key is used when consecutively inputting characters assigned to the same key, so that a current input character can be distinguished from the next input character.
- the [sep] key is also well known and a detailed description thereof will be omitted herein.
- the [mode] key is used to change a character mode in the text mode.
- the key processing unit 300 changes a first character of each key of the first and second key selection units 100 and 200 to an upper case as shown in Fig. 9. This is called a sentence mode in which the first character is input as an upper case and the rest are input as lower cases. It is preferable that the character mode is changed to the lowercase mode after a first character is input as an upper case.
- the upper case "E”, "W” and “Q” are input when the [Ewq] key is pressed once, twice, and third times, respectively.
- a changed alphabet may be automatically assigned in the first and second key selection units 100 and 200.
- English alphabets are automatically changed and assigned in the order of [eWq], [ewQ] and [Ewq].
- the key processing unit 300 changes the character mode to an uppercase mode and assigns upper cases to the keys of the first and second key selection units 100 and 200 as shown in Fig. 10.
- the key processing unit 300 changes the character mode to a numeral mode as shown in Fig. 11.
- the key processing unit 300 assigns an additional mode, such as Hanguel, the Korean alphabet, as shown in Fig. 12.
- the key processing unit 300 changes back to the lowercase mode shown in Fig. 8.
- Fig. 13 illustrates a symbol key mode in the text mode.
- the key processing unit 300 assigns, for example, symbols to each key of the first and second key selection units 100 and 200 as shown in Fig. 13. That is, the [sym] key allows users to input symbols in any character mode in the text mode. For example, when a symbol is input in the symbol key mode shown in Fig. 13, the key processing unit 300 processes such that the symbol is output and then the mode is returned to the previous character mode.
- the Hangeul keys shown in Fig. 12 are assigned considering the usage frequency, the relation with the continuous keyboard system etc.
- the symbol keys shown in Fig. 13 are preferably assigned considering similarity with numerals, usage frequency etc.
- the above-mentioned Hangeul array and symbol array shown in Figs. 12 and 13 are described in the above-mentioned Korean Laid-Open Patent Application No. 2004-82326, and a detailed description thereof will be omitted herein.
- Fig. 14 illustrates keys assigned when a text mode is changed to a keyboard mode.
- the key processing unit 300 changes the text mode to a keyboard mode and assigns keys of a computer keyboard to at lease some of keys of the first and second key selection units 100 and 200.
- the first and second key selection units 100 and 200 include the Esc key, Ins key, Del key, Backspace key, Combination key etc.
- Examples of the Combination key include the Shift key, Ctrl key, Alt key, and Window key, which are used together with other keys and are toggled.
- the key processing unit 300 processes the Esc key, Ins key, Del key, Backspace key, and Combination key in the same manner as the computer keyboard processes.
- the key processing unit 300 changes the color or shade of a character written on the combination key when the combination key is input, so that the toggling status can be identified.
- Fig. 15 illustrates a computer keyboard related to Fig. 14.
- Fig. 16 illustrates assigned functions keys of the keyboard.
- the key processing unit 300 assigns Fl to F12 keys of the computer keyboard as shown in Fig. 9.
- the key processing unit 300 processes Fl to F 12 keys which are input individually or in combination with the combination keys. For example, when F12 key is input on a MS-Word program, the key processing unit 300 loads a window named "Save as a different file name" like when F 12 key is input on the computer keyboard.
- Fig. 17 illustrates a computer keyboard related to Fig. 16.
- the function keys shown in Fig. 16 are ones which are marked with thick lines on the computer keyboard shown in Fig. 17.
- Fig. 18 illustrates assigned movement keys of the keyboard.
- the key processing unit 300 assigns cursor movement keys on the computer keyboard, such as " ⁇ — “ key, “ ⁇ ” key, “T” key, "I” key, Home key, End key, Page-up key, and Page-down key as shown in Fig. 14.

- Fig. 19 illustrates a computer keyboard related to Fig. 18.
- the movement keys shown in Fig. 18 are ones which are marked with thick lines on the keyboard shown in Fig. 19.
- Figs. 20 to 25 illustrate assignment of alphabet input keys of the keyboard.
- the key processing unit 300 assigns some of the English alphabets of the computer keyboard. For example, when the [ewq] key shown in Fig. 14 is input, alphabets belonging to a first character set, a second character set, or a third character set are assigned one-to-one to the keys by the key processing unit 300. When the [ewq] key is input again, alphabets belonging to a character set other than the current character set are assigned one-to-one to the keys by the key processing unit 300.
- [89] Preferably, whenever the [ewq] key is input, alphabets belonging to a first character set, a second character set, and a third character set are sequentially assigned one- to-one to the keys in this order by the key processing unit 300. That is, when the [ewq] key is first input, alphabets belonging to the first character set are assigned one-to-one to the keys by the key processing unit 300 as shown in Fig. 20. When the [ewq] key is input again in Fig. 20, alphabets belonging to the second character set are assigned one-to-one to the keys as shown in Fig. 21. In addition, when the [ewq] key is input again in Fig. 21, alphabets belonging to the third character set are assigned one-to-one to the keys as shown in Fig. 22.
- the first, second and third character sets are preferably divided based on the usage frequency of English alphabets. Therefore, the alphabets belonging to the first character set are “a”, “e”, “h”, “i”, “n”, “o”, “r”, “s”, and “t”, which have the highest usage frequency.
- the alphabets belonging to the second character set are “c”, “d”, “f”, “g”, “1”, “m”, “p”, “u”, and “w”.
- the alphabets belonging to the third character set are "b", "j", “k”, “q”, "v”, "x”, “y”, and “z”. They are preferably arranged in the alphabet array shown in Fig. 8.
- the key processing unit 300 toggles the [shift] key and changes the lower case to the upper case as shown in Figs. 23 to 25. This is similar to a case where the Shift key and an English alphabet key are pushed together on the keyboard, or where an English alphabet key is pushed with the CapsLock key turned on. That is, when an English alphabet key is pushed with the [shift] key activated, an upper case is displayed on the display.
- the user can input uppercase alphabets on the key array of the key selection units 100 and 200 shown in Figs. 23 to 25, and the key processing unit 300 processes and displays the input alphabets on the display.
- the English alphabets can be input in combination with the other combination keys, such as [ctrl], [alt] and [windows] keys.
- the key processing unit 300 loads the "Explorer window” like when the windows key and the alphabet "e” key are pushed on the computer keyboard.
- the key processing unit 300 assigns the English alphabet array shown in Fig. 8 so that one of the alphabets assigned to the keys can be input. For instance, when a computer is used with a mouse having three buttons, a first alphabet of each key is input by clicking the left of the mouse, a second alphabet is input by clicking the middle of the mouse, and a third by the right of the mouse.
- the key processing unit 300 assigns alphabets to a 3-by-3 array of nine keys among the limited number of keys of the key selection units 100 and 200.
- the alphabets on the computer keyboard are divided into a first group consisting of alphabets, which are input with a left hand, and a second group consisting of alphabets, which are input with a right hand.
- the alphabets belonging to the first group are arranged on the left or center columns of the 3-by-3 array, and the alphabets belonging to the second group are arranged on the right or center columns.
- the alphabets belonging to the first, second and third character sets, which are divided based on the usage frequency of the alphabets, are assigned one by one.
- Figs. 26 to 27 illustrate assignment of numeral and symbol keys of a keyboard.
- the key processing unit 300 assigns keys having both numeral and symbol as shown in Fig. 26.
- the symbol can be input when the [shift] key is activated. Therefore, when the [shift] key is not activated, the numerals "0" to "9" are marked thickly as shown in Fig. 26 to indicate that the numerals can be input.
- the symbols are marked thickly as shown in Fig. 27 to indicate that the symbols can be input.
- the user can input the numerals and symbols with the same keys as those of the keyboard, and the key processing unit 300 processes and outputs the input numeral or symbol on the display.
- Fig. 28 illustrates a computer keyboard related to Fig. 26.
- Figs. 29 and 30 illustrate assignment of remainder keys of the computer keyboard.
- the key processing unit 300 assigns the symbol and remainder keys of the computer keyboard as shown in Fig. 29. Different symbol and remainder keys are preferably assigned to at least some of keys of the key selection units 100 and 200. However, the same symbol and remainder keys may be assigned.
- the keys having two symbols in Fig. 29 are activated by toggling the [shift] key so that one of them can be input. That is, the key processing unit 300 activates lower symbols as shown in Fig. 29 when the [shift] key is not activated, while the key processing unit 300 activates upper symbols as shown in Fig. 30 when the [shift] key is activated.
- the user can input assigned symbol keys as well as the [print screen] key, [scroll lock] key, [pause break] key, [tab] key, and [esc] key through the key array shown in Figs. 29 and 30.
- the other combination keys such as [ctrl] key, [alt] key and [windows] key, can be activated to input keys.
