Description

Digital information processing apparatus which can input Japanese alphabet {DIGITAL INFORMATION PROCESSING DEVICE FOR CAPABLE OF INPUTTING JAPANESS ALPHABET}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital information processing apparatus, and more particularly, to a digital information processing apparatus that can easily input a Japanese alphabet that is difficult to be digitalized.

With the rapid development of electric and electronic technologies, various types of communication terminal devices such as pagers, CDMA, PCS, TDMA, GSM, AMPS, IMT-2000, and various electronic devices such as PDAs, game machines, remote controls, cameras, home appliances, etc. It is miniaturized and advanced.

In particular, recently, new home appliances that add communication and computing functions to traditional home appliances such as TVs and refrigerators are being released one after another. As such, as computing functions and communication functions have been added to conventional home appliances, there has been a demand for an alphabet input device capable of inputting a specific alphabet into various electronic devices, including home appliances of these new concepts, such as so-called Internet home appliances.

However, these electronic devices are not only considered to be an important factor in design, but are also small in size, and thus cannot increase the number of keys as much as a computer keyboard. For this reason, there is a demand for an alphabet input device capable of inputting and processing all alphabets used in a specific country by using only about 10-20 keys (buttons), and research is being conducted for each country.

As is well known, there are many kinds of letters in the world, but they can be divided into two types, phonetic and ideographs, depending on whether or not the meaning is given to unit syllables. According to another aspect, depending on whether or not the unit syllables can be divided into phonemes, it can be divided into two types, lowercase letters and syllable characters. Representative examples of the phonetic letters include English, Japanese, and Korean, and examples of the phonetic letters include Chinese. Representative examples of syllable characters include Japanese, and representative examples of lower case letters include English and Korean.

As such, there are at least four types of characters existing on the earth. Developing a Unicode input device that is applicable to all of these characters is very difficult, and in the case of existing Unicode input devices, the character composition rules In addition, since the number of keys required for inputting a single alphabet is complicated, there is a great deal of research into an alphabet input device capable of simultaneously using and using English, which is a national language, in each country.

The Japanese alphabet used in the present invention is 46 basic characters (phonetic notation) and the upper right of the basic characters or It consists of twenty-five mutant letters (muckyum or halftone), and eight subscripts, ア, イ, ウ, エ, オ, ツ, ヤ, ユ, ヨ, and these alphabets are again represented by Hiraka and Katakana. It is divided into types, and the number reaches 151 in total.

As such, since the number of Japanese alphabets is large, when the Japanese alphabet, which is a syllable character, is divided into syllable units and assigned to each key, even if a computer 103 keyboard or 106 keyboard is used as an input device, a separate character for generating mutated characters is used. The function key of must be provided. Furthermore, if you assign the Japanese alphabet to syllable units on a dial pad that has only a few dozen keys, you will need to assign at least four alphabetic characters per key, so you can enter even the basic characters. Up to four key operations are required. In particular, the number of key manipulations is further increased in the case of using both hirakana and katakana in parallel, or in the case of inputting a sound tone or a semitone sound.

Conventionally, a method of inputting a combination of one to three English keys corresponding to the pronunciation of the Japanese alphabet to be input and then processing them as Japanese alphabet is displayed again, and using the keys assigned by the Japanese alphabet in units of rows. The direct input method was used.

For example, if you want to enter Hiragana or "こ", press the key assigned with "k" in English and the key assigned with "o" in sequence, or press the key marked "か" five times. , After pressing the key marked "ka" once, the shift key or the direction key had to be pressed four times.

Therefore, according to the current Japanese input method, the number of key operations differs from alphabet to alphabet, and in order to input alphabets belonging to the "O" stage, the keys must be operated five times. There are many disadvantages.

Accordingly, an object of the present invention is to provide a digital information processing apparatus capable of inputting Hiragana and Katakana, which are Japanese alphabets, in an easy way.

Another object of the present invention is to extract the graphic elements that can be commonly used in the Japanese alphabet written in syllable units, define them as basic shapes (strokes), and combine the strokes to generate hiragana or katakana by a predetermined synthesis rule. It is to provide a digital information processing device that can be.

It is also an object of the present invention to provide a digital information processing apparatus capable of conveniently inputting mutated characters such as Japanese sound, half sound and tactile sound.

It is still another object of the present invention to provide a Japanese digital information processing apparatus capable of selecting and inputting hiracana and katakana.

(Example)

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a view showing the appearance of a portable telephone 10 which is one of digital information processing apparatuses. Referring to FIG. 1, a portable telephone 10 according to a preferred embodiment of the present invention includes a keypad 100_A and a display unit 200. The keypad 100_A includes stroke keys 110_A to which two strokes are assigned, a variant character generation key 120 for generating mutated characters such as a table sound and a semitone sound, and a subscript generation for converting an input Japanese alphabet into a tactile sound or a bass sound. A conversion key 130, a direction key 140 for moving a cursor, a hiragana-katakana conversion key 150, and other special function keys 160 and 170 are provided. The portable telephone 10 shown in FIG. 1 has stroke keys 110_A corresponding to strokes extracted from katakana, but may include stroke keys corresponding to strokes extracted from hiragana. This will be described later in detail.

In this embodiment, the hirakana and katakana single characters are input by the so-called anti-jata method, which is completed by pressing a series of two keys. When the mutant character generation key 120 is pressed after a character of the listening か, さ, た or は line is input, the characters of the listening か, さ, た or は line are the characters of the line 탁, ざ, だ or ば line. Is converted. In addition, when the mutant character generation key 120 is pressed after the letter of the listening line is input, the character of the listening line is converted into the letter of the line B, which is a halftone sound. If the letter of the step I except the vowel and the half vowels YA, YU or YO is input and then the subscript generation conversion key 130 is pressed, the half vowels YA, YU or YO become smaller to the subscript size. After subscript is input and subscript generation conversion key 130 is pressed, つ is converted into a tactile sound. For convenience of description below, letters corresponding to Takum and Bantaum will be referred to as "mutant letters" and letters subscripted to other letters as "subscripts", respectively.

The Japanese alphabet input mode of the cellular phone 10 includes a hiragana input mode and a katakana input mode. The hiragana input mode and the katakana input mode are alternately selected each time the hiragana to katakana conversion key 150 is pressed, and the current input mode is displayed in a predetermined area of the display unit 200.

FIG. 2 is a diagram showing the circuit configuration of the portable telephone 10 shown in FIG. Referring to FIG. 2, the portable telephone 10 includes a controller 100, an alphabet database 400, and a word database 500 as well as the keypad 100_A and the display unit 200 illustrated in FIG. 1. The alphabet database 400 stores katakana and hiragana information corresponding to pressing of a series of stroke keys 110_A and function keys 120-160. The word database 500 stores words and frequency information of the words. The keypad 100_A transmits a signal corresponding to the pressed key to the controller 300. The controller 300 reads the hiragana or katakana corresponding to a series of signals input from the keypad 100_A from the alphabet database 400, displays the hiragana or katakana in a predetermined region of the display unit 200, and inputs the input from the keypad 100_A. Words corresponding to a series of signals are read from the word database 500 and displayed in a predetermined area of the display unit 200. In this case, the words displayed on the display unit 200 are words that have a high frequency of use.

Table 1 shows 20 figures extracted from katakana consisting of a total of 46 characters, and the katakana related to each figure. In this embodiment, each figure is defined as a stroke.

The strokes are placed on an alphabet input such as a keyboard, keypad or touch screen equipped with at least 10 keys.

The portable telephone 10 as shown in FIG. 1 has a limited number of keys that may be provided in the keypad 100_A. Therefore, two strokes are allocated to one stroke key. However, in the case of an input means having a large number of keys that can be used like a computer keyboard, one stroke will be assigned to one key, that is, in a 1: 1 correspondence.

In addition, the basic figures shown in two pairs may be combined and displayed on the key surface in a different manner from the present embodiment. Further, since the arrangement of these keys is not essential to the present invention, for example, the positions of the respective function keys can be changed. In addition, the subscript generation conversion key 130 may perform a given function alone or in combination with the stroke keys 110_A.

Table 2 below shows the katakana corresponding to the order in which the stroke keys are pressed when 20 basic strokes according to the present invention are each assigned to one stroke key (and thus 20 stroke keys), and Table 3 shows the above. When the basic strokes are most appropriately combined in two and assigned to one stroke key (and thus ten primary keys), it shows the katakana corresponding to the order in which the stroke keys were pressed. 3 is an enlarged view of stroke keys 110_A, a variant character generation key 120, and a subscript generation conversion key 130 of the keypad 100_A shown in FIG.

In Tables 2 and 3, only the katakana input to the digital information processing apparatus is displayed as a series of stroke keys are pressed, but it is obvious that hiragana can also be input using the hiragana-katakana conversion key 150 as described above. Do.

As can be seen from Table 2, the digital information processing apparatus of the present invention selects and inputs two of the 20 basic figures according to the alphabetical order of the alphabet (Katakana standard) to input all 46 basic characters. You can enter

In addition, although not shown in Tables 2 and 3, if the mutant character generation key 120 is pressed once after the characters か, さ, た or は, are entered, the characters か, さ, た or は are The sound is converted to characters on the が, ざ, だ, or ば line. In addition, if the mutant character generation key 120 is pressed twice in succession after the character of the listening line is inputted, the character of the listening line is converted to the character of the line 인, which is a halftone sound. In addition, by using the subscript generation conversion key 130, the sound and the sound may be input. In other words, Table 2 and Table 3 omit the synthesis rules of A, I, W, E, O, ツ, ヤ, ユ, and 사용, which are used as subscripts. It can be solved simply by pressing the character generation key 120 or by pressing the subscript generation conversion key 130. In particular, ツ, ヤ, ユ and 되는, which are frequently used as subscripts, may be configured to be selected by using a direction key or the like after directly pressing a subscript generation conversion key without inputting a primary key.

FIG. 4 illustrates a modification in which the keypad 100_A of the portable telephone 10 shown in FIG. 1 is configured differently. Referring to FIG. 4, the stroke keys 110_A and the mutated letter generation key 120 are the same as those shown in FIG. 1, but the subscript generation converter 130_1 is different from the subscript generation converter 130 shown in FIG. 1. Otherwise enter the note directly. That is, when the subscript generating converter 130_1 is pressed once, ャ, twice in succession, ュ and three times in succession, a signal corresponding to ョ is input to the controller 300 and displayed on the display unit 200. do.

On the other hand, periods in punctuation Key or After pressing the key can be generated by pressing the variant character generation key (120), the comma is Can be generated by operating the key twice in succession. Can be generated by pressing the key twice in succession. Also, long vowel marks (-) as in "ノ-ト" (note) or Can be displayed by inputting twice.

Subsequently, a process of inputting Japanese words into the portable telephone 10 will be described. An example word is プ レ ザ ン ト which means "gift".

First, two strokes of the stroke keys 110_A included in the keypad 100_A are sequentially pressed twice, and then the mutated character generation key 120 is pressed once. Stroke keys from keypad 100_A , And Signals corresponding to the pressing of are transmitted to the controller 300. The control unit 300 inquires the alphabet database 400 and strokes the keys. , And F corresponding to pressing of is read out and displayed on the display unit 200. The remaining letters "レ ザ ン ト" are also sequentially input through the above-described process.

Another method for inputting the 'preset' into the portable telephone 10 is as follows.

First, the user strokes keys , And Press. The control unit 300 is stroke keys , And 'F' corresponding to pressing of is read out from the alphabet database 400 and displayed on the display unit 200. Then, the controller 300 searches the word database 500 and extracts, for example, up to five of the words including 'プ' in the dark, and displays them in a predetermined area of the display unit 200. do. Therefore, when the user has a desired word among the words displayed on the display unit 200, the user may select by pressing the direction key or the selection key. On the other hand, if there is only one word including the extracted alphabet in the dark, it is preferable to automatically display the word on the display unit 200.

However, if there is no desired word among the words displayed on the display unit 200, one of the following two methods may be selected. For example, when a specific function key to which word search function is assigned among the keys arranged on the keypad 100_A is pressed, five of the remaining words that are not initially displayed because the frequency of use is low and include 'プ' are dark. The display unit 200 is displayed. Alternatively, after the word 'fre' is input, 1 to 5 words including 'fre' in the dark are displayed according to the frequency of use.

On the other hand, since Japanese uses katakana and hirakana differently, as shown in FIG. 1, basic strokes are based on katakana, but by placing a hirakana-katakana conversion key 150 on the keypad 100_A as necessary. It is desirable to be able to switch the input mode.

Furthermore, it is preferable that the word entered in the hiragana input mode be displayed in kanji and the ending in hirakana (okuricana) in accordance with the so-called cultural Japanese notation.

FIG. 5 shows that strokes extracted by decomposing hiragana in the keypad 100_B of the portable telephone 20 are assigned to the stroke keys 110_B as another embodiment of the present invention. The portable telephone 20 illustrated in FIG. 4 includes a keypad 100_B and a display unit 200 in the same manner as the portable telephone 10 illustrated in FIG. 1. The keypad 100_B is a variable key generation key 120 for generating mutated characters such as stroke keys 110_B assigned to two strokes, a table sound, and a semitone sound, and a subscript generation for converting an input Japanese alphabet into a tactile sound or a bass sound. A conversion key 130, a direction key 140 for moving a cursor, a hiragana-katakana conversion key 150, and other special function keys 60 are provided. Strokes extracted from hiragana are assigned to respective stroke keys 610 of the keypad 600 illustrated in FIG. 5. In the portable telephone 10 shown in Fig. 1, the ten number keys are assigned a stroke key, the '*' key is assigned a variant character generation key, and the '#' key is assigned a subscript conversion key. However, as shown in FIG. 5, since the strokes extracted from hiragana must all be assigned to 12 keys, in this embodiment, the function keys 160 and 170 used for other purposes in FIG. 120 and the subscript conversion key 130 are used. The stroke assigned to the 12 stroke keys is , , , , , , , , , , And to be.

6A to 6C collectively show key pressing sequences for inputting Hiragana 46 characters. 6A-6C, the hiragana kanji is input to the portable telephone 20 by pressing two or three stroke keys. For example, 'ぁ' is the stroke keys And It is input by pressing sequentially. As another example, 'か' is the stroke keys , And It is input to the portable telephone 20 by sequentially pressing. However, stroke keys And In combination with the to form a hiragana kanji Only stroke keys And Stroke keys for entering 'か' when is input , And Is considered pressed. Keys written in parentheses '()' in FIGS. 6A to 6C indicate keys that can be omitted. According to this method, the hiragana 46 characters can be input to the portable telephone 20 by pressing two stroke keys, respectively. Meanwhile, 'ひ' is the stroke keys And Entered by pressing And Can be entered by pressing.

In addition, stroke keys 110_B of the portable telephone 20 illustrated in FIG. 5 are respectively assigned strokes extracted from hiragana. As described above, hiragana / katakana converter 150 is used to input not only hiragana but also katakana. can do.

In general, the keys provided in the portable telephones 10 and 20 are so small that it is very difficult to simultaneously display strokes extracted from katakana and figures extracted from hiragana on the keys at the same time. Accordingly, the manufacturer of the portable telephone 10, 20 assigns and extracts strokes extracted from hiragana to keys or assigns strokes extracted from katakana to keys according to a user's request. Of course, as described above, even if employing any method, it is possible to input both the hiragana and katakana using the hiragana / katakana converter 150.

7A and 7B show that the present invention is applied to personal digital assistants (PDAs) which are other examples of digital information processing apparatus. 7A and 7B, reference numeral 30 denotes a PDA, reference numerals 31_A and 31_B are keypads, and reference numeral 32 is a first display portion for displaying input characters, and reference numeral 33 is a hiragana / key associated with a pressed key. It is a second display unit in which words related to katakana or input hiragana / katakana are displayed. Among the keys provided in the keypads 31_A and 31_B, reference numeral 34 is a hiragana / katakana converter 34, reference numeral 35 is a variant character generation key, and reference numeral 36 is a subscript conversion key.

As is well known, most PDAs employ a touch screen. Therefore, in the present invention, each time the user presses the hiragana / katakana converter 34, the hiragana input mode and the katakana input mode are alternately selected, and the keypad arrangement of the displayed keypad is changed. That is, in the katakana input mode, as shown in FIG. 7A, the keypad 31_A to which the strokes extracted from the katakana are assigned is displayed, and in the hiragana input mode, the strokes extracted from the hiragana are allocated as shown in FIG. 7B. The keypad 31_B is displayed. Accordingly, the user can easily input hiragana / katakana to the PDA by using strokes extracted from katakana when inputting katakana and using strokes extracted from hiragana when inputting hiragana. Since the method of inputting hiragana / katakana to the PDA is the same as the method of inputting hiragana / katakana to the portable phone described above, detailed description thereof will be omitted.

8A and 8B illustrate an example of a method of inputting katakana into a PDA. First, referring to FIG. 8A, a stroke key is used to input 'コ' into the PDA 30. When you press, the stroke key The katakanas that can be entered by combination with are 'ヒ', 'ユ', 'コ', 'ロ' and 'ヨ'. The key required to enter Katakana 'ヒ', 'ユ', 'コ', 'ロ' or 'ヨ' , , , or to be. Thus, the keypad 30_A has strokes , , , And Instead 'ヒ', 'ユ', 'コ', 'ロ' and 'ヨ' are displayed. Accordingly, the user may input 'コ' by pressing 'コ' among the katakanas 'ヒ', 'ユ', 'コ', 'ロ' and 'ヨ' shown on the screen.

According to the present invention as described above, it is possible to provide the convenience of the katakana input to beginners who are not familiar with the katakana strokes of the present invention or those who do not remember the arrangement of the katakana strokes, and to shorten the katakana input time.

FIG. 8B exemplarily shows what is displayed on the first and second display units 32 and 33 of the PDA 30 when 'CO' is input by the user. Referring to FIG. 8B, 'CO' input by the user is displayed on the first display unit 32, and three words 'CORO' is used frequently among words related to 'コ' on the second display unit 33. ',' コ ツ プ 'and' コ ビ ロ 'are displayed. If the word to be input by the user is one of the three words, the user selects a desired word by using an input means such as a stylus. According to this method, since the user does not have to input the spelling of the word that the user wants to input, the katakana input time is shortened. If the word to be input by the user is not among the three words, the next letter may be directly input by using the strokes displayed on the keypad 31_A.

9A and 9B illustrate an example of a method of inputting hiragana into a PDA. First, referring to FIG. 9A, in order to input 'ふ' into the PDA 30 When the key is pressed Hiragana that can be entered by the combination of and is 'ら', 'ふ', 'う' or 'え'. And the next stroke needed to enter hiragana, ら, ふ, う, or え , , or to be. Therefore, the PDA 30 strokes the keypad 31_B. , , And Display 'ら', 'ふ', 'う' or 'え' at the position of. Therefore, the user may input 'ふ' by pressing 'ふ' among the four hiragana 'Ra', 'ふ', 'う' or 'え' displayed on the keypad 31_B.

According to the present invention as described above, it is possible to provide the convenience of hiragana input to the beginners who are not familiar with the hiragana strokes of the present invention or to those who do not remember the arrangement of the hiragana strokes, and to reduce the hiragana input time.

FIG. 9B exemplarily shows what is displayed on the first and second displays 32 and 33 of the PDA 30 when 'ふ' is input by the user. Referring to FIG. 8B, 'ふ' input by the user is displayed on the first display unit 32, and three words with a high frequency of use among words related to are displayed on the second display unit 32. ',' ふ ね (船) 'and' ふ ゆ (冬) 'are displayed. If the word to be input by the user is one of the three words, the user selects a desired word by using an input means such as a stylus. According to this method, the hiragana input time is shortened because the user does not have to input the spelling of the word that the user wants to input. If the word to be input by the user is not among the three words, the next letter may be directly input by using the strokes displayed on the keypad 31_B.

While the invention has been described using exemplary preferred embodiments, it will be understood that the scope of the invention is not limited to the disclosed embodiments. Accordingly, the claims should be construed as broadly as possible to cover all such modifications and similar constructions.
