Description

  The present invention relates to a character input control method, a character input program, and a character input device that allow a character to be easily input using a direction instruction means such as a cross control key.

In general, when characters or the like are input using a personal computer (hereinafter referred to as a PC) or the like, the user inputs the target buttons (keys) of the input device connected or attached thereto by operating the user. be able to. In game machines and the like, software keyboards have also been proposed in which characters are input by pointing keyboard keys displayed on a display. In addition, a mobile phone or the like is well known as a device capable of inputting characters (for example, see Patent Document 1).
JP 2002-268803 A

  However, in the character input described above, it is necessary to search for a button to which a target character is assigned from among a large number of buttons on the input device, and it is necessary to remember a different button arrangement for each input device.

  In addition, in a device having an input device with few buttons to be input, such as a mobile phone, a plurality of characters are assigned to one button. Therefore, a button to which a target character is assigned is found and operated. , You need to find the character you want.

In addition, since the place for confirming the input character (input confirmation unit) and the place for outputting the character determined to be input ( determined character output unit ) are far from each other, it is necessary to move the eyes alternately. For example, the hardware keyboard, a button input confirmation section on the keyboard, determines the character output unit is a Display Lee screen, the soft keyboard, the input confirmation unit buttons on the soft keyboard displayed on the display screen, determining the character output unit also a display screen, is the mobile phone, the input device buttons, determining the character output unit is to correspond to the display screen, determining the character output unit and the input confirmation unit in any of the devices are separated.

  Furthermore, when the input confirmation part is displayed on the display screen like a soft keyboard, there is a disadvantage that a wide range of the display screen is occupied for inputting characters.

  In view of such a point, the present invention can easily input characters without having to remember the button arrangement of an input device such as a keyboard, and can reduce the area on the display used for character input. An object is to propose a character input control method, a character input program, and a character input device.

In order to solve the above-described problems and achieve the object, a first means of the present invention is to input a character using a direction indicating means, and a character array consisting of one or a plurality of character types is defined as a character specific coordinate. Correspondingly stored in the character table in advance, a partial character table of a predetermined size is displayed on the display means as an input confirmation unit composed of the central selected character part and the surrounding character selection reference part. Have a process to do. In addition, in the character selection reference part of the input confirmation part, characters arranged around the character displayed in the selected character part on the character table are displayed, and the selected character is selected according to the operation of the direction indicating means. In the section, any one of the characters around the selected character part displayed in the character selection reference part is moved and displayed, and the character selection reference part around it is moved to the selected character part on the character table. It has a process of displaying characters arranged around the character and redrawing the input confirmation unit . Further, when the target character is displayed when the target character is displayed in the selected character portion, the input confirmation unit is moved by one character and redrawn, and the character in the selected character portion is input to the input confirmation unit. It has processing to display horizontally.

According to such first means, the input confirmation unit can feel as if the character table is looked up from above, and a part of the character table can be seen by the input confirmation unit. It is possible to easily guess where the target character is without having to memorize complicated input methods.
In addition, since the input confirmation unit for confirming the character to be input and the determined character output unit for outputting the character determined to be input are arranged very close to each other, the distance for moving the line of sight when inputting the character is shortened.

The second means of the present invention displays a boundary line corresponding to the end of the character table on the input confirmation section when the character selection reference section includes a character in contact with the end of the character table in the first means. It is characterized by doing.

According to such second means, the boundary line corresponding to the end of the character table is displayed on the input confirmation unit, so that the user can grasp the whole image of the character table, which is a guideline for searching for the target character. .

Third means of the present invention, in the above-described second means, the character to be displayed on the input confirmation unit, if such a one end of characters on the character table to a character on the other end, the upper end of the character table It is characterized by displaying the boundary line of the lower end or the boundary line of the left end and the right end.

According to such third means, by connecting the boundary line between the upper end and the lower end of the character table, or the boundary line between the left end and the right end, the character displayed on the input confirmation unit becomes the character at one end on the character table. Can be moved across the border from one character to the other.

According to a fourth means of the present invention, in the first means described above, the character table is color-coded in advance corresponding to the character type, and the background color of the character is displayed according to the character type of the character displayed on the input confirmation unit. It is characterized by that.

According to the fourth means, since the background color is color-coded for each character type displayed in the input confirmation unit, it can be used as a guide when the user searches for the target character.

According to a fifth means of the present invention, in the first means described above, the partial character table has a size of 3 × 3 matrix.

According to the fifth means, by setting the partial character table to a size of 3 × 3, an input confirmation unit having a minimum size capable of displaying the characters in the selected character portion and the characters in the surrounding character selection reference portion. can do.

  According to the present invention, the input confirmation unit has a feeling that the character table is seen from above and a part of the character table can be seen by the input confirmation unit, and the character selection reference unit is displayed. It is possible to easily guess where the target character will be without learning a simple input method, and intuitive character input can be realized with a simple procedure. Furthermore, since the partial character table is cut out from the character table and displayed, the area occupied by the display screen can be reduced when inputting characters, and the present invention can be applied to a device having a small display such as a portable electronic device.

  In addition, because the input confirmation unit that confirms the character to be input and the determined character output unit that outputs the character that is determined to be input are arranged very close, the distance to move the line of sight when inputting characters is shortened, The effect that the troublesomeness which moves eyes | visual_axis can be reduced is acquired.

  In addition, by displaying a boundary line corresponding to the end of the character table on the input confirmation part, the user can grasp the entire image of the character table, so that it becomes a guide when searching for the target character, and the user's The effect which can reduce a burden is acquired.

  In addition, by connecting the boundary line between the top and bottom edges of the character table, or the boundary line between the left and right edges, the character displayed in the input confirmation part is changed from the character at one end to the character at the other end on the character table. Since the boundary line can be moved, the effect of facilitating the input of characters at distant positions on the character table can be obtained.

  In addition, since the background color is color-coded for each character type displayed in the input confirmation unit, it becomes an index when searching for a target character, and an effect that the user can easily search for the target character is obtained.

  In addition, the partial character table is a 3 × 3 matrix, and the size of the input confirmation unit made up of the selected character part and the surrounding character selection reference part is minimized, so that the display screen of the input confirmation unit when inputting characters is used. An effect of reducing the occupied area can be obtained. In particular, it is effective when displaying what is known by a general arrangement such as a hiragana 50-syllabary.

Hereinafter, an example of an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a portable character input device (hereinafter referred to as a character input device) of an example of an embodiment, but is not limited to this example. This character input device includes a display 1 as a display means, a selected character determination key 2 for determining a selected character, an up movement key 3 constituting a cross controller as a direction indicating means, a right movement key 4, and a down movement key. 5. Similarly, the left shift key 6, a character table switching key 7 for changing the input character type, an input end key 8 for ending the character input function, a determined character output unit 9 for displaying a character determined to be input , a selected character and an input The input confirmation unit 10 displays a character selection reference unit that is a candidate for a character to be displayed. The above-described key group constitutes an input device 14 to be described later.

  In this example, the input confirmation unit 10 displays a part of a character table as shown in FIGS. 9, 10, 11, and 12 (hereinafter referred to as a partial character table) for a 3 × 3 matrix. At that time, the background color of the character is displayed by color information set for each character type of each table to be described later. However, since the color cannot be directly expressed, a dotted line as shown in FIG. Represents a color region.

  FIG. 2 is a block diagram showing a configuration example of a hardware environment (character input device) for operating the character input program of the present invention. A CPU (Central Processing Unit) 15 has a function of performing overall control and calculation, and is a control means for performing various processes according to a character input program and other control programs stored in a ROM (Read Only Memory) 17. A RAM (Random Access Memory) 16 is storage means for writing and reading information according to instructions from the CPU 15. The ROM 17 is a storage unit that performs reading according to an instruction from the CPU 15. Information about the character table is stored here. The bus 18 is information transmission means directly connected to the CPU 15 and can exchange information with storage means.

  The input receiving unit 19 notifies the CPU 15 that the user has pressed any of the input devices 14. The image processing unit 20 outputs the data drawn by the CPU 15 in the RAM 16 to the display 1, and the display 1 displays the image.

  FIG. 3 shows a detailed view of the input confirmation unit 10. The input confirmation unit 10 includes a central selected character unit 12 and a character selection reference unit 13. In the selected character portion 12, the character currently selected by the user (not yet determined at this time) is displayed in the middle of the displayed partial character table. The character selection reference unit 13 displays characters arranged in eight directions around the character of the selected character unit 12 on the character table, and is displayed for reference when the user searches for a target character. Further, when the character selection reference unit 13 includes a character in contact with the end of the character table, the character table boundary line 11 is displayed for reference when the user searches for the target character.

  When the currently displayed character of the selected character portion 12 is the character specific coordinate (n, m) of the character table, any one of the up movement key 3, the right movement key 4, the down movement key 5, and the left movement key 6 is pressed. When pressed, the partial character tables displayed on the input confirmation unit 10 are (n, m−1), (n + 1, m), (n, m + 1), (n−1, m) character specification, respectively. A character having coordinates is arranged in the selected character portion 12. The character selection reference unit 13 displays characters around the characters displayed on the selected character unit 12 after movement in the character table.

  When these processes are repeated and the target character is displayed on the selected character portion 12, when the selected character determination key 2 is pressed, as an example, the input confirmation portion 10 moves to the right by one character and is redrawn. The character of the selected character portion 12 is displayed in the determined character output portion 9 on the left side of the input confirmation portion 10. When the character table switching key 7 is pressed, the character tables such as “Hiragana”, “English characters”, “symbol characters”, etc. can be switched. When the input end key 8 is pressed, the input confirmation unit 10 disappears and the character input ends.

  The object correlation of the character input program recorded in the ROM 17 of this example will be described.

  A character table object (Character Tables) 21 holds a character table such as “Hiragana”, “English characters”, and “symbol characters”.

  The input confirmation part display object (Input Area Display) 22 displays a partial character table from the character table of the character table object 21. Further, the character specific coordinates of the character arranged at the center of the partial character table are held. Furthermore, an up / down / left / right movement key processing object (↑ → ↓ ← Key) 23, an input character determination key processing object (Input Key) 24, a character table switching key processing object (Select Table Key) 25, an input end key processing object (End Key) ) In response to the notification from 26, the character specifying coordinates of the character displayed on the selected character portion 12 which is the center of the input confirmation portion 10 are updated and held, and the input confirmation portion 10 is redrawn.

  The up / down / left / right movement key processing object 23 determines and holds the state of whether the up / down / left / right movement keys 3, 4, 5, 6 have been pressed. When the button is pressed, the input confirmation unit display object 22 is notified.

  The input character determination key processing object 24 determines and holds the state of whether or not the input determination key 2 has been pressed. When the button is pressed, the input confirmation unit display object 22 and the determined character output object 27 are notified.

  The character table switching key processing object 25 determines and holds the state of whether or not the character table switching key 7 has been pressed. When the button is pressed, the input confirmation unit display object 22 is notified.

  The input end key processing object 26 determines and holds the state of whether or not the input end key 8 has been pressed. When the button is pressed, the input confirmation unit display object 22 is notified.

  The determined character output object 27 receives a notification from the input character determination key processing object 24, acquires the character specific coordinates of the character displayed at the center of the input confirmation unit 10 held by the input confirmation unit display object 22, and determines the character. It is displayed on the character output unit 9.

  Next, with reference to the flowcharts of FIGS. 5 and 6 and the display examples of FIGS.

  Here, it is assumed that the character input device has been initialized for character input (step 0). First, a character input menu or the like (not shown) is selected, and a character table selected by the user via the input device is loaded into the RAM 16 (step S1) and initialized. And the input confirmation part 10 is displayed on the upper left part of the display 1, and the character specific coordinate (n, m) of the character of the selection character part 12 of the center is acquired and hold | maintained in RAM16 (step S2).

The display of the input confirmation unit 10 in the initial state is as shown in FIG. 7A, for example. In this example, “ki” is displayed in the selected character portion 12. Black lines 11 displayed at the upper end and right end of the input confirmation unit 10 are boundary lines of the character table.

  Next, it is determined whether or not the selected character determination key 2 has been pressed (step S3). If not, it is determined whether or not the character table switching key 7 has been pressed (step S4). If the character table switch key 7 is pressed, the process returns to step S1 to load another character table.

  If the character table switching key 7 is not pressed in the process of step S4, it is determined whether or not the input end key 8 is pressed (step 5). If it is determined that the input end key 8 has not been pressed, it is determined whether or not any direction indicating means has been operated. For example, first, it is determined whether or not the up movement key 3 is pressed, whether or not the down movement key 5 is pressed down, whether or not the right movement key 4 is pressed down further, and whether or not the left movement key 6 is pressed down again. (Steps S6 to S9).

  When it is determined that the movement key has been operated in any of the processes in steps S6 to S9 described above, for example, when the up movement key 3 in step S6 is pressed, the character specific coordinates of the character of the selected character portion 12 are changed. m is changed to m-1 (step S10). When the down movement key 5 in step S7 is pressed, m of the character specific coordinates is changed to m + 1 (step S11), and the right movement key 4 in step S8 is pressed. If it is, the character specific coordinate n is changed to n + 1 (step S12), and when the left movement key 6 in step S9 is pressed, the character specific coordinate n is changed to n-1 (step S13). And the character drawing in the input confirmation part 10 is performed based on the coordinate after a change (step S14).

Figure 6 shows a flow chart of a character rendering processing of the input confirmation unit in step S 14. When the input confirmation unit 10 is notified to perform character drawing, character drawing is started (step S23). First, the character specific coordinates (n, m) of the character of the selected character part 12 are acquired (step S24). Next, based on the character specific coordinates of the selected character part 12, the character coordinates of the surrounding character selection reference part 13, (n + 1, m-1), (n, m-1), (n-1, m- 1), (n + 1, m) (n-1, m), (n + 1, m + 1), (n, m + 1), (n-1, m + 1) are acquired (step S25).

  It is determined whether or not the character specifying coordinates of the character selection reference unit 13 described above are outside the character table or at the end of the character table (step S26). If it is outside the character table or the coordinates of the end of the character table, a boundary line representing the boundary of the character table is drawn in the input confirmation unit (step S27). Furthermore, if the character specific coordinates of the character selection reference unit 13 are outside the character table in step S26, the character table is replaced with characters above and below (left and right) the character table (step S28). That is, the upper and lower ends (the same applies to the left and right ends) of the matrix of each character table are connected on the display of the input confirmation unit 10.

  And after drawing the background color of the input confirmation part 10 by the color predetermined for each character type (step S29), after drawing each character of the selection character part 12 and the character selection reference part 13 (step S30), Drawing of the input confirmation unit 10 is finished (step S31), and the process proceeds to step S3 in FIG. If the character specifying coordinates of the character selection reference unit 13 are not outside the character table or the end of the character table in step S26, the process proceeds to step S29 and the same processing is performed.

  For example, when the left movement key 6 is pressed once from the state shown in FIG. 7A, the input confirmation unit 10 is updated and redrawn, and “shi” is displayed in the selected character unit 12. Further, when the down key 5 is pressed three times, “So” is displayed as shown in FIG. 7C. At this time, according to the color information of the character table of FIG. 9, the background of the 50-sound character is painted in color 1 and the background of the muffled character is painted in color 2 so that the user can easily find the target character. Is displayed. In addition, in this example, the background of the semi-voiced character is color 3, the lowercase character is color 4, and the background of the character assigned by using the empty area is painted in color 1 'and displayed on the input confirmation unit 10. .

If none of the movement keys is pressed in the processes in steps S6 to S9, or after the character drawing process of the input confirmation unit 10 in step S14, the process returns to step S3. When the selected character determination key 2 is pressed in step S3, the input confirmation unit 10 is deleted (step S15), and the characters in the selected character unit 12 are output to the left of the place where the input confirmation unit 10 was present (step S). 16 ).

At this time, it is determined whether or not there is a display space on the right side of the input confirmation unit 10 on the display 1 screen (step S 17 ). When the right side of the input checking unit 10 there is a display space, is set (step S 18) the display location of the input confirmation unit 10 to one character to the right, to redraw the input confirmation unit 10.

For example, when the selected character determination key 2 is pressed in the state of FIG. 7C, “SO” is displayed in the determined character output unit 9 on the left side of the input confirmation unit 10, and the input confirmation unit 10 has one space character on the right side because there is a space on the right side. The image is moved and redrawn, and the state shown in FIG. 7D is obtained. Similarly, when the up key 5 is pressed four times and the right button is pressed five times, the state shown in FIG. 7E is obtained. The black line displayed on the input confirmation unit 10 is the boundary line 11 of the character table. The upper and lower ends (the same applies to the left and right ends) of each character matrix are connected on the display of the input confirmation unit. When the selected character decision key 2 is pressed, “ra” is displayed in the decision character output portion, and the input confirmation portion 10 is redrawn after moving to the right by one character as described above, resulting in the state shown in FIG. 7F.

When there is no display space to the right of the input confirmation unit 10 displays packed on the line that has been input (step S19). And the display place of the input confirmation part 10 is set to the following line (step S20), and it redraws.

  As described above, the character input process is repeated according to the flowcharts of FIGS. When the character input end key 8 is pressed in step S5, the character input confirmation unit 10 is deleted from the display 1, and the input line is displayed on the top (step S21), and the character input is ended. (Step S22). FIG. 7G shows a state after the character input end key 8 is pressed from the state of FIG. 7F.

  In this way, when characters on a certain line are being input, the line spacing between that line and the previous line is increased in order to display the input confirmation unit 10, but if the input of that line is determined, the line spacing is reduced. Thus, the display screen used for character input can be saved.

  Alternatively, if the input confirmation unit 10 is displayed translucently, the display of another application is not completely hidden, so that the display screen used for character input can be used more effectively. For example, there is an advantage that even when characters are input, the display of other applications such as time display is not completely hidden. Moreover, when the input confirmation part 10 is made semi-transparent display, you may display so that the input confirmation part 10 may overlap with the already displayed character display. FIG. 8A shows a normal display example, and FIG. 8B shows a display example that overlaps with the character display already input by the input confirmation unit 10.

  FIG. 9 to FIG. 12 show examples of character tables arranged by character type such as characters and symbols. FIG. 9 is an example of a character table in which hiragana characters are arranged based on a generally known 50-sound table. FIG. 10 is a continuation of the hiragana character table of FIG. Character specific coordinates on the character table are represented as (n, m). In addition, a character displayed on the display is shown in the upper part of a frame representing one character specific coordinate, and the lower part shows a background color (color information) displayed on the input confirmation unit 10. “* (N, m)” means that the same character as the character having the character specific coordinates “(n, m)” is displayed when the character is displayed on the input confirmation unit 10. In this way, an empty area on the character table can be used effectively, or it may be left blank.

  Also, if the shape of the entire character table is not a rectangle but an uneven shape, for example, in a character table with an uneven shape on the right side as shown in FIG. 12, if the left move key 6 or the right move key 4 is kept pressed, the display of each line is It is displayed repeatedly connected left and right. For example, when “# ♭ ♪” in the second row of the character table in FIG. 12 is displayed on the input confirmation unit 10, if the right movement key 4 is continuously pressed, “# ♭ ♪ # ♭ ♪ # ♭ ♪ ... “” Is repeatedly displayed. Alternatively, it may be left blank according to the length of the upper or lower row at this time.

  FIG. 11 shows an example of an English character table. FIG. 12 is an example of a character table of symbol characters. In the example of FIG. 12, the character table is arranged as follows and is color-coded for easy understanding by the user. The first line from the top is punctuation, etc. The second line is characters used in music, the third line is graphic characters, the fourth line is arrow characters, the fifth line is characters used in mathematics, the sixth line is Roman numerals, etc. It is.

  As described above, according to the present example, the up / down / left / right movement keys 3, 4, 5, 6 and the input confirmation unit 10 constituting the cross controller maintain the physical arrangement relationship in the up / down / left / right directions. Input is possible without looking at the cross controller. Furthermore, the input confirmation unit 10 is intuitively viewed through a simple procedure without having to learn a complicated input method as if a part of the character table is displayed on the input confirmation unit 10 as if looking from the top. You can input characters. In addition, by displaying the character selection reference unit 13, the user can easily guess where the target character is and can input characters intuitively.

  In addition, since the place for confirming the input character (input confirmation unit 10) and the place for outputting the character determined to be input (determined character output unit 9) are arranged very close to each other, it is possible to look at the time of character input. You can input smoothly without moving.

  The types of characters that can be placed in the character table are not limited to “Hiragana (50-sound table)”, “English characters”, and “symbols”, but can also be applied to “pictograms” and Korean anti-cuttables that are known for general layout . In particular, when the present invention is applied to a generally known arrangement such as a 50-sound table, and a 3 × 3 matrix display is performed, for example, characters displayed on the input confirmation unit Although the user knows the arrangement even though the number is small, it is possible to input characters intuitively using the input device (direction indicating means), thereby occupying the display screen of the input confirmation unit used for character input. The display area can be further reduced.

As the direction instruction means, it is only necessary to be able to input a target direction, and various devices such as a trackball, a keyboard, and an instruction lever capable of indicating a direction can be applied. Or direction indication by pen input is also possible. For example, when moving the character of the selected character portion 12 of the input confirmation unit 10 shown in FIG. 1 to move to the left, “shi” is touched with the pen tip, or the left end portion of the input confirmation unit 10 is touched, Alternatively, a direction indication can be input by a gesture input in which “ki” is touched with the pen tip and moved to the left end of the input confirmation unit 10 while being in contact with the display surface. Therefore, the present invention can also be applied to a pen input type electronic device.

  Further, in the example of the above-described embodiment, the instruction input in the cross direction is performed by the direction instructing unit. However, using a trackball or the like, an oblique direction, that is, an upper right, a lower right, a lower left, an upper left is performed. It is also possible to change the character specifying coordinates so as to be moved obliquely on the character table in accordance with the operation, and display the characters in the selected character portion and the character selection reference portion.

  In the example of the above embodiment, the conversion function such as kanji conversion is not mentioned. For example, the character string displayed on the determined character output unit is converted into a desired kanji by pressing a conversion button (not shown). Further, by performing an operation such as pressing the selected character determination key, the input and output of the converted character may be confirmed and the conversion may be realized.

The partial character matrix displayed on the input confirmation unit is not limited to a 3 × 3 partial character table, but may be N × M (N, M: natural number ) according to the data structure of the character table. For example, what is known by a general arrangement such as a hiragana 50-sound table only needs to be able to display a partial character table of about 3 × 3 on the input confirmation unit. However, if the general arrangement is not known, such as the English letters arranged in FIG. 11, the user can more easily search for the target character by displaying a partial character table of about 5 × 3.

  Moreover, although the place (input confirmation part) which confirms the character currently inputted with software is mounted, since the area which occupies a display screen when inputting a character can be made small, as a character input device, a mobile phone, The present invention can also be applied to an electronic device having a small display such as a so-called sub-notebook PC, a small word processor, a PDA (Personal Digital Assistance), an electronic notebook, or a portable game machine.

  In addition, the present invention supplies a recording medium recording software program codes for realizing the functions of the above-described exemplary embodiments to a system or apparatus, and a computer (or a control device such as a CPU) of the system or apparatus. Needless to say, this can also be achieved by reading and executing the program code stored in the recording medium. As a recording medium for supplying the program code in this case, for example, a flexible magnetic recording medium, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a DVD, a magnetic tape, a nonvolatile memory card, Various things such as ROM can be used.

  Further, the present invention is not limited to the above-described embodiments, and various other configurations can be taken without departing from the gist of the present invention.
