US 7165022 B2Abstract
Initials of the Chinese language are classified into nine initial groups. The first touch of a numeric key of a cellular phone selects an initial group including the initial of the desired syllable for input. Then, guidance is displayed corresponding to a final group to which the final of the desired syllable belongs. The syllable is determined based on the operation according to the guidance. The present invention classifies finals into the first final group composed of simple finals, the second final group composed of complex finals that start with a, e, or o, the third final group composed of complex finals that start with i, or y, the fourth final group composed of complex finals that start with u, or w, and the fifth final group composed of complex finals that start with v, or yu.
This application is a continuation-in-part of U.S. patent application Ser. No. 09/968,010, filed on Oct. 2, 2001, which in turn claims conventional priority of Japanese Patent application No. 2001-179120, disclosures of which are incorporated herein by reference. The subject matter contained in Japanese Patent application No. 2002-5780, filed on Jan. 15, 2002, is also incorporated herein by reference.
It is an object of the present invention to provide a program product, an apparatus, and a method for defining a Chinese syllable with a small number of keystrokes of a limited number of keys to realize user-friendly input of the Chinese language.
The present invention will be explained below with reference to the accompanying drawings in accordance with the embodiments.
FIG. 1 is a block diagram schematically showing a cellular phone's configuration relating to the process for inputting the Chinese language according to the first embodiment. FIG. 2 is a schematic diagram showing the appearance of the cellular phone.
The second final group is composed of complex finals which are each transcribed into groups of letters in which the first letter is a, e, or o in Pinyin. The third final group is composed of complex finals which are each transcribed into groups of letters in which the first letter is i or y in Pinyin. The fourth final group is composed of complex finals which are each transcribed into groups of letters in which the first letter is u or w in Pinyin. The fifth final group is composed of complex finals which are each transcribed into groups of letters in which the first letter is v or the first letters are yu in Pinyin. According to this embodiment, the first to fifth final groups are symbolized by “?”, “*”, “i* or y*”, “u* or w*”, and “v* or yu*”, respectively. The alternative symbol representations of the third through fifth groups (y*, w*, and yu*) are used when the respective complex finals have the zero initial. It should be noted that the first letter of a final of the third to fifth final groups in their Pinyin transcription, i (or y), u (or w), and v (or yu), are known under the designation of head vowels. While finals classified into one of the third to fifth final groups include head vowels, those classified into the second final group include no head vowel.
When the button pushed at the initial selecting stage 24 a is “qchc” in FIG. 5, the screen (D7) in FIG. 10 is displayed on the displaying part 12. According to the screen (D7) in FIG. 10, in the positions where 1, 2, 3, 4, 5, 6, 7, 8, and 9 are displayed in FIG. 4, “q?,” “qi*,” “qu*,” “ch?,” “ch*,” “chu*,” “c?,” “c*,” and “cu*” are displayed, respectively.

At step S17 the controller 20 judges the tone based on the input via cursor 14 by the user, and displays a screen including denotation of the tone. The processing returns to S3. More specifically, the controller 20 judges that the first tone has been designated if the upward direction of the cursor 14 was input, the second tone has been designated if the right direction of the cursor 14 was input, the third tone has been designated if the downward direction of the cursor 14 was input, or the fourth tone has been designated if the left direction of the cursor 14 was input. Then the controller 20 assigns “1” if the first tone is designated, assigns “2” if the second tone is designated, assigns “3” if the third tone is designated, or assigns “4” if the fourth tone is designated, to display the screen including both the “syllable” of the syllable tables D11–D99 in FIG. 11 and one of “1”–“4” assigned corresponding to the tone which should follow to said “syllable,” on the second displaying part 12.
In the state P10, the Chinese characters are displayed corresponding to the syllables “dianhuaji” which mean a telephone set on the first displaying part 11. On the second displaying part 12, the alternatives of the initial groups in the initial table D are displayed for the next input of a syllable.
The second embodiment of the present invention adopts the configuration according to the first embodiment characterized in that the Chinese input program with the input module is implemented for determining a syllable by two to four keystrokes. A user of a cellular phone with the Chinese input program operates the phone to get in the Chinese input mode, and can determine a syllable of the Chinese language by two to four keystrokes.

The conversion to a Chinese character will be described below. The Chinese input mode for input of Chinese language is further classified into the phonetic input mode for input phonetic symbols according to Pinyin or Bopomofo, the conversion mode for conversing the inputted phonetic symbols to a Chinese character, and the document editing mode for editing strings of inputted Chinese characters. The phonetic input mode is switched to the conversion mode, when the button “CNV” is pressed which is shown in FIG. 27 corresponding to the initial state of the phonetic input mode.
FIG. 38 is the explanatory diagram showing the switch between the phonetic input and conversion modes. The phonetic input mode is switched to the conversion mode, when the button “CNV” is pressed which is displayed in the initial state of the phonetic input mode. In the conversion mode, the characters corresponding to the phonetic symbols (syllable) which have already inputted, are displayed on the displaying part 12 as ten buttons. The user can determine the character by selecting desired one of the displayed characters. After the determination of the character, the conversion mode is switched to the phonetic input mode.
In the conversion mode, besides the aforementioned characters, the buttons “INPUT” and “SHIFT” are also displayed. When the “INPUT” button is pressed, the conversion mode is switched to the phonetic input mode. The button “SHIFT” is used with the cursor 14.
In the case that the button “SHIFT” is pressed and the upward direction of the cursor 14 is designated, ten characters with the highest frequency of use are displayed. In the case that the button “SHIFT” is pressed and the downward direction of the cursor 14 is designated, ten characters with the lowest frequency of use are displayed.
If the conversion is made based on a word instead of a character, the user can move the target for selection among those with the same pronunciation to left by a character by designating the left direction of the cursor 14, and move the target to right by a character by designating the right direction of the cursor 14. The user also move the target to left by a word by pressing the button “SHIFT” and designating the left direction of the cursor 14. The user also move the target to right by a word by pressing the button “SHIFT” and designating the right direction of the cursor 14.
FIG. 39 is the explanatory diagram showing the switch between the phonetic input and document editing modes. The phonetic input mode is switched to the document input mode, when the button “EDT” is pressed which is displayed in the initial state of the phonetic input mode. In the document editing mode, on the displaying part 12 are shown buttons of “CUT,” “COPY,” “PASTE,” “UNDO,” “SEARCH,” “REPLACE,” “RANGE,” “TAB,” “INSERT,” “INPUT,” “SPACE,” and “SHIFT.” Among these buttons, “CUT,” “COPY,” “PASTE,” “UNDO,” “SEARCH,” “REPLACE,” “RANGE,” “TAB,” “INSERT,” and “SPACE” is used by the user for editing a document in a manner similar to a usual editor program.
The button “INPUT” is used for switching modes. More specifically, the document editing mode is switched to the phonetic input mode when the button “INPUT” is pressed. The button “SHIFT” is used with the cursor 14. More specifically, when the button “SHIFT” is pressed and the left direction of the cursor 14 is designated, the cursor moves to the beginning of a line. When the button “SHIFT” is pressed and the right direction of the cursor 14 is designated, the cursor position moves to the end of a line. When the button “SHIFT” is pressed and the upward direction of the cursor 14 is designated, the cursor position moves to the front of the document. When the button “SHIFT” is pressed and the downward direction of the cursor 14 is designated, the cursor position moves to the end of the document. Further, the user can use functions such as registration of a word, selecting dictionaries, and switch between the simplified and traditional character sets by operating the button “SHIFT” with another button.
When the input is a keystroke to the button “CNV” (S106; Yes), the process of conversion to a Chinese character, which will be described below with reference to FIG. 42, is executed. When the input is a keystroke to the button “EDT” (S107; Yes), the process of editing, which will be described below with reference to FIG. 43, is executed. When the input does not corresponds to the aforementioned inputs, the process corresponding to the same input, which is assigned to the pressed button, is executed (S108).
The process of the conversion to a Chinese character will hereinafter be described with reference to FIG. 42. The process of conversion is executed, when the input made at the phonetic input mode is the keystroke to the button “CNV” (FIG. 40: S106; Yes). To begin with, the controller 20 displays the characters with the same pronunciation corresponding to the syllable entered by the latest input on the second displaying part 12 (FIG. 42: S301). Then, the controller 20 is on standby until the user's input is made (S302). With the input, the controller 20 causes the processing branch on the basis of whether the input designates a character to confirm the conversion or not (S303).
The process of editing will hereinafter be described with reference to FIG. 43. The process of editing is executed, when the input made at the phonetic input mode is the keystroke to the button “EDT” (FIG. 40: S107; Yes). To begin with, the controller 20 displays the initial screen of the editing mode on the second displaying part 12 (FIG. 43: S401). Then the controller 20 is on standby until the user's input is made (S402). With the input, the controller 20 causes the processing branch on the basis of whether the input is a keystroke to the button “SHIFT” or not (S403).
When the input is a keystroke to the button “SHIFT” (S403; Yes), the controller 20 displays buttons indicating respective editing functions hidden from view of the initial screen (S404), and returns the processing to S402.
When the input is not a keystroke to the button “SHIFT” (S403; No), the controller 20 causes the processing branch on the basis of whether the input designates the switch to the phonetic input mode or not (405). More specifically, in the case the input designates the switch to the phonetic input mode (S405; Yes), the controller 20 returns the processing to S101 in FIG. 40. In other cases (S405; No), the process corresponding to the same input is made (S406), the processing returns to S402.
FIG. 44 is an explanatory diagram showing assignment of initials to the cursor. As shown in FIG. 44, for example, when the initial group of dt is selected at the initial screen of the phonetic input (FIG. 27), “d” and “t” are assigned to the upward and right directions of the cursor 14, respectively. When the initial group of gkh is selected, “g,” “k,” and “h” are assigned to the upward, right, and downward directions of the cursor 14, respectively. When the initial group of jzhz is selected, “j,” “zh,” and “z” are assigned to the upward, right, and downward directions of the cursor 14, respectively. When another initial group is selected, the assignment is made similar to the above description. It should be noted that when the initial group of rφ is selected, “r,” “',” “y,” and “w” are assigned to the upward, right, downward, and left directions of the cursor 14, respectively.
For instance, to input the Chinese word corresponding to “telephone” which is transcribed into “dian-hua-ji” according to Pinyin, the user selects the initial group of dt, and inputs the initial d by designating the upper direction of the cursor 14. Then, the user selects the initial group of gkh, and inputs the initial h by designating the downward direction of the cursor 14. Further, the user selects the initial group of jzhz, and inputs initial j by designating the upward direction of the cursor 14. With the aforementioned input, the Chinese input program specifies the word composed of Chinese characters corresponding to “telephone” based on the input of d, h, and j, and displays the specified word on the first displaying part 11.
