Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character input device for selecting a character to be input from a group of characters displayed on a screen using a cursor key and inputting the selected character into a device.

[0002]

2. Description of the Related Art Recently, as a method of inputting characters and the like to various devices, a method of inputting characters and the like using an input pad such as a home-use game machine has been used in addition to using a keyboard. This is to select a character to be input using a character group and a cursor displayed on the screen and a cursor key for moving the cursor, and input the character to the device. The details are disclosed in Japanese Patent Laid-Open No. 62-173516, and characters are input in the following procedure. That is,
First, for example, a list of alphabets is displayed on the screen. The operator moves the cursor displayed on the screen to the character to be input by operating the cursor key, and presses the character input key to determine the character to be input. The determined characters are input to the device.

[0003]

By the way, there are cases where it is desired to input characters without being known to a third party, such as inputting a password to game software or inputting a personal identification number in a bank automatic teller machine. In the above conventional technique, it is possible to easily recognize or guess the character string input by the operator from the information on the position and movement of the cursor displayed on the screen. Therefore, when inputting a highly confidential character string or number such as a password, there is a high risk of leakage of confidentiality.

There is also a problem that the key operation for moving the cursor to the character desired by the operator is troublesome and the operation takes time. The present invention has been made in view of such circumstances, and it is a first object of the present invention to provide a character input device in which it is difficult for a third party to recognize what the input character string is. A second object of the present invention is to provide a character input device in which the key operation when moving the cursor does not take time.

[0005]

In order to achieve the first object, the invention of claim 1 is a display means having a display screen, and a character group display for performing control to display a character group on the display screen. A control means, a plurality of cursors designating a plurality of characters on the displayed character group, a cursor set display means for displaying as one cursor set, and an operator's instruction,
Cursor moving means for moving the cursor set on the display screen, cursor selecting means for selecting one of the cursor sets according to an instruction by an operator's hand operation, and outputting a character indicated by the selected cursor. And output means.

In order to achieve the second object, the invention according to claim 2
In the invention, the cursor moving means has a configuration in which, when moving the cursor in the arrangement direction of the cursor set, the cursor movement means moves the cursor set by skipping by the number of characters corresponding to the number of arranged cursors. . In order to achieve the second object, the invention of claim 3 is characterized in that the cursor moving means includes a cursor moving instruction receiving unit that receives a cursor group moving instruction from an operator, and the cursor moving instruction receiving unit is a cursor group moving unit. When the move instruction is accepted, the instruction is given to the pre-movement character group holding unit that holds the character group specified by the cursor set before the movement and the character group that the pre-movement character group holding unit holds. The destination character group holding unit that holds the character group that is moved by one character in the moving direction, the character group that the previous character group holding unit holds and the character that the destination character group holding unit holds The common character presence / absence determining unit that determines whether or not a common character exists by comparing with the group, and when it is determined that a common character exists, the character group in the destination character group holding unit Further directed movement Move to the character group rewriting unit that rewrites the character group at the position moved by one character toward the target character group and the common character presence / absence determining unit compares until the character group before moving determines that there is no common character A character set rewriting unit rewrites the character group, and when it is determined that no common character group exists, a cursor set display means for displaying the cursor set at the position of the destination character group after rewriting. And a cursor set display instructing section for instructing to.

[0007]

According to the first aspect of the present invention, the cursor set display means displays the cursor set for designating a plurality of characters on the character group displayed on the display screen. According to an instruction from the operator, one of the cursors in the cursor set is selected by the cursor selecting means. The character designated by the selected cursor is output by the output means.

According to the second aspect of the present invention, the cursor set is moved by skipping the number of characters corresponding to the number of arranged cursors by the instruction of the operator. According to the invention of claim 3,
The common character presence / absence determining unit compares the character group held by the pre-movement character group holding unit with the character group held by the destination character group holding unit to determine whether there is a common character. It When the common character exists, the destination character group rewriting unit rewrites the character group until the common character does not exist. The cursor display instructing unit instructs the cursor set display means so that the cursor set is displayed at the position of the destination character group when the common character group no longer exists.

[0009]

1 is a block diagram of a character input device according to a first embodiment of the present invention. This figure shows the character group display control unit 1.
1, a cursor movement key 12, a reference cursor information holding unit 13, a cursor set information holding unit 14, a cursor form display control unit 15, a display device 16, a character selection key 17, and a character extraction unit 18. It is configured.

As shown in FIG. 2, the character group display control section 11 controls the display of alphabets A to Z, which is a list of characters to be input, on the display screen of the display device 16. Specifically, the character group display control unit 11 has a table of the characters of the alphabet and the coordinates of the characters as shown in FIG. 5, and by using this table, each character of the alphabet is displayed on the screen. Control to display. In FIG. 5, the first column 501 shows the letters of the alphabet to be displayed on the screen. The second column 502 is
The coordinates of the characters in the first column 501 on the screen are shown. Here, as shown in FIG. 6, the coordinates on this screen are in a coordinate system that takes values from here to 640 in the x direction to the right and 480 in the y direction downward, with the upper left corner of the screen as the reference (0, 0). Coordinates.

The cursor movement key 12 is used for the cursor 21, the cursor 22, and the cursor 22 of FIG. 2 displayed on the display screen.
This is a key for moving the cursor 23 vertically and horizontally. Specifically, in the input pad used for the home-use game machine as shown in FIG. 7, it is a key group including an up arrow key 71, a down arrow key 72, a right arrow key 73, and a left arrow key 74. Here, the cursor has three horizontally aligned shapes as shown by the cursor 21, the cursor 22, and the cursor 23 in FIG. 2, but the cursor movement key 12 is the cursor that serves as a reference among the three cursors. Move 22. The cursor 21 and the cursor 23 are the cursor 22
Based on the position of, the cursor is displayed one position to the right and one position to the left. Therefore, the cursor 22
When is moved, the cursor 21 and the cursor 23 are displayed with the position of the cursor 22 after the movement as a reference, and as a result, the cursor 21 and the cursor 23 are moved together with the cursor 22. Such three cursors that move in union are called one cursor set, which will be described in detail in the cursor set information holding unit 14.

The reference cursor information holding unit 13 holds the character pointed to by the reference cursor 22 in the cursor set and the coordinates of the character. When the cursor movement key 12 is further operated, the cursor 2 which is the reference after movement is moved.
The character indicated by 2 and the coordinates of the character are acquired and held, and the character and the coordinates of the character are passed to the cursor set information holding unit 14. Specifically, if the cursor set is currently displayed as shown in FIG. 2, the reference cursor information holding unit 13 displays the character “J” indicated by the reference cursor 22 and the coordinates (200, 160) is held. Next, when the up arrow key 71 of the cursor movement key 12 is pressed, the reference cursor information holding unit 13 uses the correspondence table shown in FIG. , And find the coordinates of the character. Here, FIG. 8 is a correspondence table for calculating the position of the cursor that is moved by operating the cursor movement key 12. In the correspondence table shown in FIG. 8, the first column 81 from the left indicates the character at the position where the current cursor is. The sixth column 82 shows the coordinates of the characters shown in the first column 81. The second column 83 shows the character at the position of the cursor that is moved by operating the right arrow key 73 (RIGHT). For example, as shown in line 801, when the cursor is currently at the character "A", it indicates that the cursor is moved to the character "B". The third column 84 is

The display device 16 is controlled to display 33 as a cursor set. Further, in the cursor set information holding unit 14, the character “P” and its coordinates (120,
240), the letter "J" and their coordinates (200, 160)
And the character "D" and its coordinates (280, 80) are held, the display device 16 uses the cursor 41, the cursor 42, and the cursor 43 of FIG. 4 as a cursor set based on the coordinates of these characters. Control to be displayed on.

The display device 16 is a CRT display that displays information from the cursor form display control unit 15 and the character group display control unit 11. The character selection key 17
A group of keys for selecting a character pointed by each cursor of the cursor set. For example, in the input pad of the home-use game machine as shown in FIG. 7, "A key",
The "B key" and the "C key" correspond to them.

The character extracting unit 18 is provided with the above-mentioned correspondence table shown in FIG. 8 and outputs the character to be input to the outside based on the key selected by the character selection key 17. For example, in the cursor group information holding unit 14, as shown in FIG. 2, "A key", "B key", "C"
Characters corresponding to "key" are "I" and "J" respectively
It is assumed that "K" is held. At this time, when the "A key" is selected with the character selection key 17, the character "I" corresponding to the "A key" held in the cursor set information holding unit 14 is taken out and the character is output to the outside. To do. Similarly for the "B key" and "C key", the corresponding characters "J" and "K" are output to the outside.

Next, the overall operation of the character input device in this embodiment will be described with reference to the flow chart shown in FIG. First, it is assumed that a cursor set having the cursor indicating the character "J" as shown in FIG. 2 as the reference cursor 22 is displayed on the screen. If neither the character selection key nor the cursor set key is pressed by the operator, it waits until they are pressed in that state (steps S1201 and S1203). When the character selection key is pressed by the operator (step S1201), the character indicated by the cursor of the cursor set corresponding to the pressed character selection key is output (step S1202). For example, as a character selection key,
If the "A key" is pressed, the character "I" corresponding to the "A key" is output. When the cursor movement key is pressed (step S1203), the reference cursor information in the cursor set is updated based on the pressed cursor movement key (step S12).
04). Specifically, if the right arrow key 73 (RIGHT) of the cursor movement keys is pressed, the character after the reference cursor 22 is moved is acquired and held by using the correspondence table shown in FIG. The character "J" of the reference cursor 22 that is present is updated to "K". Next, the cursor set information is updated based on the updated reference character “K” of the cursor 22 (step S1205). Specifically, the characters "L" and "J" indicated by the cursor to the right of "K" and the cursor to the left are acquired and held by using the correspondence table shown in FIG. In this way, when the information of the cursor set is updated, based on the updated information of the cursor set "J", "K", and "L", the cursor set after moving to the right is displayed (step S120
6). After that, the process returns to step S1201 and this process is repeated thereafter.

Next, a character input device according to the second embodiment of the present invention will be described. This embodiment is different from the first embodiment in that the cursor set is always moved by one character by one operation of the cursor movement key, but by one operation, a plurality of characters are moved by one operation. It's different. FIG. 13 is a block diagram of a character input device in the second embodiment of the present invention. This figure has a configuration in which a cursor movement amount determination unit 133 is newly added to the configuration of the first embodiment shown in FIG. Therefore, the character group display control unit 131, the cursor movement key 132, the reference cursor information holding unit 134, and the cursor set information holding unit 1 in FIG.
35, the cursor form display control unit 136, the display device 137, the character selection key 138, and the character extraction unit 139, respectively, are the character group display control unit 1 shown in FIG.
1, a cursor movement key 12, a reference cursor information holding unit 13, a cursor set information holding unit 14, a cursor form display control unit 15, a display device 16, a character selection key 17, and a character extraction unit 18. Therefore, the description is omitted.

The newly provided cursor movement amount determination unit 133 will be described below. Cursor movement determination unit 1
When the cursor movement key 132 is operated, 33 determines whether to move the cursor to a position where the character shown in the cursor set before the move does not overlap with the character shown in the cursor set after the move. It has a function of giving an instruction to move the cursor set based on the determination to the reference cursor information holding unit 134 and the cursor set information holding unit 135. FIG. 14 is a diagram showing an internal configuration of the cursor movement amount determination unit 133. This figure shows a pre-movement cursor group information holding unit 1331 and a movement permission / inhibition determination unit 1.
332 and a movement instruction unit 1333.

Pre-movement cursor set information holding unit 1331
When the cursor movement key 132 is operated, holds the character pointed by each cursor in the cursor set held by the cursor set information holding unit 135 before moving. For example, if the cursor set currently exists at the position shown in FIG. 17A, the characters “I”, “J”, and “K” held by the cursor set information holding unit 135 are held.

The moveability determination unit 1332 determines whether or not there is at least one character that is overlapped with the character held by the pre-movement cursor set information holding unit 1331 and the character held by the cursor set information holding unit 135. If there is a duplicate character, the movement instruction unit 1333 is activated. The movement instruction unit 1333 is activated by the movement permission / inhibition determination unit 1332 and moves the cursor set in the direction designated by the cursor movement key 132 for one character to the reference cursor information holding unit 134 and the cursor set information holding unit 135. After giving an instruction to do so and moving the cursor set, the moveability determination unit 1332 is activated. However, the cursor movement key 13
When the movement instruction unit 1333 has already been activated three times after 2 is operated once, the movement possibility determination unit 1332
Does not start.

Next, the overall operation of the character input device according to this embodiment will be described with reference to the flow charts shown in FIGS. First, it is assumed that a cursor set having a cursor indicating the character “J” as a reference cursor as shown in FIG. 17A is displayed on the screen. When the operator presses, for example, the "A key" as a character selection key (step S1)
501), "I" is output as the character indicated by the cursor of the cursor set corresponding to the pressed character selection key (step S1502). When the cursor movement key is pressed (step S1503), the character indicated by each cursor in the current cursor set is held and the counter n is set to 1 (steps S1504 and S1505). In this case, the held characters are the characters "I", "J", "K" because the cursor set is at the position shown in FIG. 17 (a). Next, the reference cursor information is updated based on the pressed cursor movement key (step S1506), and the cursor set information is updated based on the updated reference cursor information (step S1507). . Specifically, when the right arrow key 73 (RIGHT) is operated as the cursor movement key, the cursor set when the cursor set moves right by one character from the position 171 of FIG. 17A is shown. Update the contents held in the power character and the coordinates of that character. The updated characters are "J""K""L". Next, it is determined whether or not there is a duplicate character between the character indicated by the cursor of the updated cursor set and the held character (step S1508). In this case, since it is determined whether or not there is a duplicate character in “I”, “J”, “K” and “J”, “K”, “L”, it is determined that there is a duplicate character. If there are overlapping characters, it is then determined whether n ≧ 3 (step S1509). In this case, since it is determined that n ≧ 3 is not satisfied from n = 1, n is incremented next (step S1510) and the process proceeds to step S1506. Hereinafter, similarly, step S1506 to step S15
10 is repeated, or it is determined in step S1508 that there are no duplicate characters, or step S1
If n ≧ 3 at 509, the cursor set moved based on the updated cursor set information is displayed (step S1511). In this case, the cursor set is as shown in FIG.
The cursor set was moved to the position 172 in FIG. 17B, but it is further moved to the position 173 in FIG.
Move to position 174 in (d). Position 1 in FIG. 17 (d)
Only after moving to 74, it is judged that there is no overlapping character with the first retained character, and the position 1 in FIG.
The cursor set is displayed at 74. Then, the process proceeds to step S1501, and the character selection key or the cursor movement key is accepted (steps S1501 and S15).
03).

The cursor set is not limited to the form shown in FIGS. 2, 3 and 4, but has other forms.
The cursor set information holding unit 14 may hold information for forming such a cursor set. Also,
The cursor form display control unit 15 is configured to perform display control so as to change the color and shape of each cursor in the cursor set in order to clarify the correspondence between each cursor and the character selection key in the cursor set. May be.

[0029]

As described above, in the invention of claim 1, a plurality of cursors are displayed as one cursor set, one of the cursors in the cursor set is selected by the operator, and the selected cursor is selected. Since the character indicated by is output by the output means, it is not possible for a third party who is looking at the screen to know which cursor character in the cursor set has been selected, and a character string such as a highly confidential password has been input. Even in this case, there is an effect that it is difficult for a third party to guess what the input character string is.

According to the second aspect of the invention, even if a character string such as a highly confidential password is input, it is difficult for a third party to guess what the input character string is. When the cursor is moved in the arrangement direction of the cursor set, there is an effect that the cursor set is moved by skipping the number of characters corresponding to the number of arrangements of the cursor.

According to the third aspect of the invention, even if a character string such as a highly confidential password is input, it is difficult for a third party to guess what the input character string is. By operating the cursor movement key once, the cursor is moved until the same character does not exist in the character group indicated by the cursor set before the movement and the character group indicated by the cursor set after the movement. It is possible to reduce the number of times the cursor movement key is operated, and it is advantageous that the key operation when moving the cursor does not take time.
