Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a character input device, a character input method, and a character input program, for example.
[0002]
[Prior art]
Conventionally, the mainstream of character input methods using a pointing device is a matrix format that lists typical characters on a screen, including a software keyboard.
[0003]
In the case of the character input device adopting the above matrix method, a process of displaying a related character having the same attribute as the representative character in the vicinity by moving the cursor to the representative character is performed.
[0004]
The reason why such a display method is used is that there is a restriction on the usable screen size depending on the device. That is, the number of characters that can be displayed is limited. When many characters are displayed, the size of the characters to be displayed may be inevitably reduced, which leads to a decrease in operability.
[0005]
Devices that can benefit from adopting the matrix method described above include mobile phones, PDAs, game machines and the like. Naturally, the number of display characters is limited due to the screen size. For example, in the case of a mobile phone, the shape and size are considered from the viewpoint of portability, and the screen size is reduced.
[0006]
As described above, in the case of a mobile phone, the advantage of applying the matrix method is large due to the limitation of the screen size, and displaying the representative characters (for example, hiragana) first improves usability for the user (patent) Reference 1). The PDA and the like are the same as in the case of the mobile phone in terms of merits obtained from the matrix system.
[0007]
In the case of a game-dedicated machine, in order to advance the game content in response to the user's button operation, the input operation mainly includes character operation, command input, and the like. Therefore, many keypads do not have many buttons. Thus, in the case of a game-only machine, the advantage of applying the matrix method is great due to the limitation on the number of buttons, and displaying the representative characters (for example, hiragana) first improves usability for the user ( Patent Document 2).

[Problems to be solved by the invention]
However, in the conventional matrix method, when a related character is displayed near the character from a representative character and a desired character is selected, the related character is often displayed based on the point position of the cursor. Therefore, the arm stroke accompanying the user's operation meanders, and the operation may be difficult. Since many click operations are required from the selection of the representative character to the selection of the desired character, there are many problems in terms of operability.
[0010]
Accordingly, the present inventor has focused on the point that characters are input like a blind touch on a normal keyboard, even with a software keyboard, with respect to a stroke from selection of a representative character to selection of a desired character.
[0011]
SUMMARY OF THE INVENTION An object of the present invention is to provide a character input device and a character input capable of easily inputting characters by only a regular pointer movement operation with respect to the software keyboard while limiting the software keyboard on the display screen to the minimum necessary number of display characters. To provide a method and a character input program.

[0036]
The display 20 has a function of displaying menus, statuses, display objects, and the like associated with various processes of the CPU 14. The keyboard 21A includes keys for inputting characters (hiragana, alphabets, numbers, symbols), buttons for inputting a power on / off signal, cursor keys for operating a pointer position on the screen, function keys, and the like. Composed. The mouse 21B has functions for operating a pointer position on the screen, selecting a range on the screen, selecting an icon, and the like, like the cursor keys.
[0037]
The memory 22 has a function of storing a program 22A, a first palette display table 22B, a second palette display table 22C, a function palette display table 22D, a data memory 22E, and the like. The program 22A includes a program that realizes the character input function of the present invention. Note that the program 22A includes, for example, a program that is stored in an executable format through a network.
[0038]
The first pallet display table 22B is pallet data that is displayed first when characters are input. For example, in the case of “Hiragana”, the representative characters “a”, “ka”, “sa” of 51 sounds are displayed. Are stored in correspondence with the characters of... And coordinate data for determining the display position. The second palette display table 22C stores character data, coordinate data for determining a display position, and the like corresponding to the characters related to each representative character stored in the first palette display table 22B.
[0039]
The function palette display table 22D stores data related to a function selection palette at the home position of the pointer position serving as a cursor. The function palette display table 22D includes, for example, data for selecting a sound repellent “n” and a prompt sound (“tsu” etc.) out of 51 sounds. The data memory 22E has a storage function for storing data files such as transmission / reception mails and image files.
[0040]
Next, the first and second palettes and the function palette described above will be described in detail. FIG. 2 is a diagram showing a display example of a palette, and FIG. 3 is a diagram for explaining a second palette display table according to the present embodiment. Here, the function palette also has the same table configuration as that of the second palette display table, and thus the description thereof is omitted.
[0041]
First, in order to display a palette and enter characters using the software keyboard, it is necessary to specify the mode of the software keyboard. Therefore, when the software keyboard mode is designated, for example, as shown in FIG. 2A, a first palette CPT1 for inputting “Hiragana” is first displayed.
[0042]
In the first palette CTP1, areas of representative characters “a”, “ka”, “sa”, “ta”,... Are arranged in a horizontal line with respect to the screen as a software keyboard. In this embodiment, “Hiragana” input is used as the initial screen. However, the present invention is not limited to this, and may be an alphabet, a symbol, or the like.
[0043]
Then, the function palette FTP is displayed as the home position of the pointer position that can be moved by the user's operation in the center in the longitudinal direction of the first palette CTP1. Z indicates a movable pointer, and the character area and the functional area can be moved according to the user's operation. The function palette FTP itself is set as a fixed position at the home position. As an example, the function palette FTP has a fan shape in which the areas of functions 1, 2, 3, 4, sound repellent “n”, and sounding sound “tsu” (an example of initial display) are radially and circumferentially separated from the center. Have.
[0044]
The second palette CPT2 has a fan shape in which the related character region is radially and circumferentially divided from the center of each representative character, as in the above-described function palette FTP. In the case of the second palette CPT2, for example, as shown in FIG. 2B, a concentric area from the center to the outside is divided into a plurality of layers according to the attributes of the related characters.
[0045]
For example, when the pointer moves to the representative character “sa”, the related characters “sa”, “shi”, “su”, “se”, and “so” areas related to the representative character “sa” are displayed. A region is set in the first layer closest to the center, and regions of related characters “za”, “ji”, “z”, “ze”, and “zo” are set in the second layer. For example, in the case of the representative character “ha”, regions of related characters “pa”, “pi”, “pu”, “pe”, “po” are set in the third layer. Whether or not to include a representative character in a related character is assumed to be either.
[0046]
In order to realize the above display form, in the present embodiment, for example, the table shown in FIG. 3 is prepared. As for the table, the second pallet will be described as a representative example. For example, as shown in FIG. 2, the second palette display table 22C is configured to store character data and position data of characters (related characters) related to the representative character in association with character groups such as “Hiragana”. It is.
[0047]
In the case of “Hiragana”, reference characters PA, PK,..., PH,... Corresponding to each character “A”, “KA”,.・ ・ Is memorized. This reference position indicates the center for displaying the second palette CPT2.
[0048]
The related character information is stored in association with the representative character. For example, the representative character “A” corresponds to the characters “A”, “I”, “U”, “E”, “O”, and the respective character data is stored. In addition, the selection area (display section) of each related character “A”, “I”, “U”, “E”, “O” is determined from the reference position PA around the reference position PA of the representative character “A”. Are determined by the distance (front and rear) and the angle in the circumferential direction (left end and right end), so these distance and angle are stored.
[0049]
The distance is variable depending on the display size on the screen, but the angle may be divided by 1/8 (45 degree section) as an example. As shown in FIGS. 2B and 3, for example, in the case of the related character “shi”, the distance data is L0 up to the front of the character “shi” region and L1 up to the depth thereof, and the angle data PSIA. May be Δθ (0 ° to 45 °).
[0050]
As shown in FIG. 2 (B), the character “ji”, which is the muddy sound of the character “shi” in the first layer, is the character “shi” in the second layer. Have the same angle data PSIA. That is, the difference in data between the character “shi” and the muddy sound “ji” of the character “shi” is only the distance data. That is, in the case of the muddy sound “ji”, the distance L1 in the back of the character “shi” is the front distance, and the distance data PZIL is a combination of this distance L1 and the distance L2 in the back.
[0051]
As for the representative character “ha”, the angle data (..., PHIA,...) And distance data (..., PHIL,. ..., Second layer angle data (..., PHIA,...) And distance data (..., PBIL,...) Are set. Since the related characters related to the representative character “ha” extend to the third layer (Pa, Pi, Pu, Bae, Po), the angle data (..., PHIA,. Only the distance data (..., PPIL,...) Is different.
[0052]
Next, this embodiment will be functionally described. FIG. 4 is a block diagram illustrating the configuration according to the present embodiment in terms of functional transition. FIG. 4 shows functions corresponding to the character input device according to the present invention in the computer of the present embodiment. As shown in FIG. 4, for example, the character input device according to the present invention includes a first palette / function palette display unit 100, a pointer position detection unit 101, a first palette area determination unit 102, a second palette display unit 103, The input stroke determination unit 104, the input character determination unit 105, the input character display unit 106, the pointer movement display unit 107, and the like are included.
[0053]
First, when the software keyboard mode is designated by the user's operation of the keyboard 21A, the first palette / function palette display unit 100 refers to the first palette display table 22B and the function palette display table 22D, and displays the first on the display 20. One palette CPT1 and a function palette FTP are displayed (see FIG. 2A). At this time, the position of the pointer Z is the home position.
[0054]
The movement direction of the pointer Z is determined according to the movement operation of the mouse 21B while the software keyboard mode continues. Therefore, the pointer position detection unit 101 detects a position signal based on, for example, a constant movement speed on the coordinates in accordance with the movement of the mouse 21B. This position signal is sent to the first pallet area determination unit 102.
[0055]
After the first pallet area determination unit 102 determines which character area (representative character) the pointer position is moving, information for specifying the moving representative character is sent to the second pallet display unit 103. Sent out. The pointer position is controlled by the pointer movement display unit 107. Then, the second palette display table 22C is referred to by the second palette display unit 103. Then, related character data related to the moving representative character is read, and the second palette CPT2 is developed centering on the representative character.
[0056]
At this time, when the pointer position is in the representative character area of the first palette FTP, the pointer position is in the neutral state with the second palette CPT2 being displayed. That is, the input stroke determination by the input stroke determination unit 104 is still impossible.
[0057]
When the pointer position is moved from the representative character area of the first palette FTP to the related character area, the input stroke determination unit 104 causes the related character area where the pointer position exists to be based on the reference position of the representative character. And the angle in the circumferential direction. At this time, the pointer movement display unit 107 controls the display of the pointer position in the second palette CPT2 based on the determination information from the input stroke determination unit 104.
[0058]
When the pointer position moves from the first palette CPT1 to the second palette CPT2 and enters any related character area in the first layer related to the representative character, the representative character in the neutral position and the related character in the first layer It is assumed that the movement of the pointer in the region up to the second layer muddy sound and the third layer muddy sound related to the related character does not lead to determination of the character.
[0059]
On the other hand, after the pointer position has moved to the second palette CPT2, an operation of moving away from the region up to the related characters of the first layer, the second layer muddy sound and the third layer semi-muddy sound related to the related character. When is performed, the character corresponding to the character region immediately before the region is removed is selected as the input character.
[0060]
A series of input strokes are determined by the input stroke determination unit 104, and by referring to the second palette display table 22C, the input character determination unit 105 causes the related characters in the first layer, the second layer muddy sound related to the related characters, and A determination is made as to whether or not the region up to the semi-voice sound of the third layer has deviated, and when it deviates, which is the immediately preceding character region.
[0061]
Referring to the example of FIG. 2B, the pointer position is moved to the representative character “sa” by the user's operation, and the pointer position is a character area from the representative character “sa” to the related character “shi”. At the stage of moving to, character input is not yet completed. The pointer position does not return from the character area of the related character “shi” to the related character “ji” in the second layer or the representative character “sa” in the neutral position, but is outside the range indicated by the angle data of the related character “shi”. In this case, the character input for the related character “shi” is selected. In the case of the related character “ji”, the character input of the related character “ji” is selected when the character is moved further than the distance L2 indicated by the distance data.
[0062]
In this way, the input character determination unit 105 determines which character has been selected based on information from the input stroke determination unit 104 and the second palette display table 22C.
[0063]
The input display unit 106 inputs the character determined by the input character determination unit 105. There is no particular rule on the display form at this time, and the display of the determined input character may be a normal character display, and the description is omitted.
[0064]
Next, a specific processing procedure will be described. 5, 6 and 7 are flowcharts for explaining the operation according to the present embodiment. The processing shown in this flowchart is executed by the program 22A described in FIG.
[0065]
First, in FIG. 5, the program is started (step S1), and the executable program resides on the memory (step S2). Thereby, the character input program according to the present invention can be executed. In this state, command input is accepted (step S3).
[0066]
That is, when the software keyboard mode is designated by command input, the first palette is displayed on the display 20 (step S4). Then, a process of moving the pointer to the home position of the first pallet is executed (step S5). This state is as shown in FIG.
[0067]
At this stage, since the second pallet is not displayed yet (step S6), the function-specific processing (see FIG. 6) is executed (step S7). After this function-specific process is executed, the process returns to step S6 while this mode continues. As will be described later, when the character input is started and the pointer position is moved from the home position, the second palette is displayed. In this case, since the second palette is displayed in the determination in step S6, the character input process (see FIG. 7) is executed (step S8). After execution of this character input process, the process returns to step S6 while this mode continues. Thus, the above process is repeatedly executed while this mode continues.
[0068]
When the process proceeds to the function-by-function process in step S6, it is determined whether or not a function has been selected (step S71). When the pointer position moves to the function area, the function is selected, although the function is not determined. Therefore, if there is a function selection, processing is selected according to the next branch condition from the pointer position at that time. That is, when the pointer position is moved within a certain functional area and does not deviate from the range of the angle data and the distance data, the function-by-function processing ends and the processing returns to step S9 in FIG.
[0069]
On the other hand, if the pointer position deviates from the range of angle data and distance data without returning to the neutral area from the function area where the pointer is located, the immediately preceding function is determined and executed (step S73). After this process is executed, the process returns to step S5 in FIG. 5 and the same process is repeatedly executed.
[0070]
Also, when the point position has once moved to the sound repellent “n”, sounding, and function areas and returned to the original neutral position, there is no function selection, and the process returns to step S9 in FIG.
[0071]
When the point position moves on the first palette and moves to the representative character area, the second palette corresponding to the representative character is displayed (step S75). Then, the process returns to step S9 in FIG.
[0072]
If there is no function selection in step S71, branching by the pointer position is also performed in this case (step S76). When the pointer position is in the neutral position (home position), or when the pointer position is moved within an invalid angle of the first layer, the process returns to step S9 in FIG.
[0073]
When the point position moves on the first palette and moves to the representative character area, the second palette corresponding to the representative character is displayed (step S77). Then, the process returns to step S9 in FIG.
[0074]
In addition, when the pointer position moves from the neutral position to the area of an arbitrary function on the function palette, the arbitrary function is selected (step S78). Then, the process returns to step S9 in FIG.
[0075]
Next, when the character input process is selected in step S6, it is determined whether or not a character is selected (step S81). When the pointer position moves to the character area, the character is selected but not determined. Therefore, if there is a character selection, the processing is selected according to the next branch condition from the pointer position at that time (step S82).
[0076]
When the pointer position is shifted from the representative character at the neutral position to a related character and the target character deviates from the region of the related character having the same angle data as the related character, the selected character is determined as the input character ( Step S83). Then, the second pallet is closed (step S84), and the process proceeds to step S5 in FIG. Then, the processing is started again from the point position being the home position.
[0077]
If the pointer position returns to the home position, the character selection is canceled (step S85), and the process proceeds to step S5 in FIG. Further, when the pointer position is changed from the representative character at the neutral position to a related character and the pointer moves between related character areas having the same angle data as the related character, the selected character is changed (step S86). ). And a process transfers to step S5 of FIG.
[0078]
Even if it is determined in step S81 that no character is selected, processing is selected based on the next branch condition from the pointer position at that time (step S87). When the pointer position is in the neutral position (home position) or when the pointer position is moved within an invalid angle of the first layer, the process closes the second pallet before step S5 in FIG. (Step S88).
[0079]
When the point position moves on the first pallet and moves to the representative character area, the changed character type, that is, the second pallet corresponding to the changed representative character is displayed (step S89). Then, the process returns to step S9 in FIG.
[0080]
If the pointer position moves from the representative character at the neutral position to a related character and moves between related character areas having the same angle data as the related character, the selected character is changed (step S90). . And a process transfers to step S5 of FIG.
[0081]
As described above, according to the present embodiment, the software keyboard on the display screen is suppressed to the minimum necessary number of display characters, and it is easy only by a regular pointer movement operation with respect to the software keyboard using a mouse (pointing device). It is possible to enter characters.
[0082]
Now, in the above-described embodiment, when the point position moves on the first pallet, the function of displaying the second pallet with the movement has been described, but the present invention is not limited to this, The second palette is displayed only when the pointer position reaches the position of each representative character on the first palette and the mouse 21B is operated to move the pointer position toward the related character area. May be.
[0083]
In the above-described embodiment, the movement of the pointer position is indicated by a visual display for the selected character and the selection function. However, the present invention is not limited to this, and the selection is being performed as the pointer moves. You may make it perform the audio | voice process which reads out about a character or a function. In this case, sound is output from the speaker 19. The audio data may be stored in the memory 22 so as to correspond to the function.
[0084]
Although the present invention has been described using a mouse as a pointing device, it can also be applied to a tablet PC that designates a point position with a stylus pen.
[0085]
