Abstract

PROBLEM TO BE SOLVED: To prevent a user from becoming unable to use a system by a minor error such as a mistake and mishearing when writing down a password. SOLUTION: The definition for making a character, a figure, and a sign for constituting the password correspond to a character possibly erroneously inputted as it character is held in a decoding program. When the password is accepted (S201) and is decoded (S202), a mutually correspondingly defined character is decoded as the same data. For example, when erroneously inputting a character 'E' as 'A', the 'E' is corrected to the same data as when decoding 'A' in a decoding process, and does not become an input error.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus, a program, and a recording medium having the program recorded therein, which receives an input to a predetermined system. More specifically, the present invention relates to a device, a program, and a recording medium that receive a code input such as a password.

[0002]

2. Description of the Related Art In the field of games, a technique of encoding certain information based on a predetermined rule and storing and transmitting it is often used. The code for storage and transmission is usually called "password".

For example, in a role-playing game, when a player interrupts the game, a password of several hiragana characters or dozens of characters is presented on the screen, and if the password is entered on a predetermined screen at a later date, the game is played. There are things that you can play the continuation of. This is a method of encoding a play record until the game is interrupted (for example, a character level, a place where the character is, a task that has been cleared, etc.) and storing it as a password.
When the game is restarted, the play record saved by decrypting the password is read.

In recent years, a service called Internet ranking has been provided. The internet ranking is a service on the internet provided by a server operated by a game maker or an individual. After playing a game on an arcade game machine, a home game machine, or the like, the player accesses the server using a mobile phone or a personal computer and applies for a play result (score, etc.). The server totals the applied play results for each game and publishes the ranking. In such a service, a password including alphabets and numbers is displayed on the game machine screen at the end of the game, and the play result can be applied by inputting the password on a predetermined screen provided by the server. That is, the play result is encoded and transmitted as a password.

In these games and services, most players memorize the presented password by writing it in a memo, and input the password while referring to the memo.

[0006]

In the above-mentioned games and services, it is naturally possible to restart the play and apply for the play result by inputting the password written down in the memo. However, in reality, there are cases where the entered password is not accepted as an error input.

One of the causes of such a problem is the player's mistaken appearance when the password is displayed on the screen. In particular, a small portable game device has a small monitor, and the displayed password may be difficult to see.
For example, characters having a similar shape when displayed on the screen, such as “me” and “nu” and “1” and “l”, are likely to be misread.

Another cause is that the memo is mistaken. Even if the characters are easily distinguishable when they are displayed on the screen, they may be difficult to distinguish when they are handwritten, especially when they are stroked or written in habit. For example, “shi” and “ku” are likely to be misread depending on the handwriting method.

Further, when several people play the game together, one player may read the password displayed on the screen aloud, and another player may hear it and write it down in a memo. For example, characters with similar pronunciations such as “b” and “v” are likely to be mistakenly heard and recorded as they are.

In such a case, for example, if it is necessary to play the role-playing game again from the beginning, or if it is not possible to apply for the play result in spite of having obtained a high score, it is terrible for the player. .

The present invention provides an input accepting device, a program, and a recording medium having the program recorded therein, which allows the error even when an incorrect password is input, when the error is a predictable error.

[0012]

An input receiving device of the present invention is a receiving means for receiving an input of a code having a character, a number or a symbol as a constituent element, and a decoding for decoding the code received by the receiving means. Means, determining means for determining whether or not the code decoded by the decoding means is appropriate as data to be processed by a predetermined system, and letters, numbers or symbols that can be input as a constituent element of the code, Defining means for defining a correspondence between the character, number or symbol and a character, numeral or symbol that may be erroneously entered, wherein the decoding means is provided for inputting based on the correspondence defined by the defining means. It is characterized in that decoding is performed so as to correct an error.

The decoding means can correct an input error by decoding the letters, numbers or symbols mutually associated by the defining means into the same data.
Alternatively, the decoding means, when the judging means judges that the decoded code is inappropriate as data to be processed by a predetermined system, at least a part of the constituent elements of the code. May be replaced with a letter, number, or symbol associated with the component by the defining means, and then the code may be decoded again.

Next, the program of the present invention includes a reception function for receiving an input of a code having a character, a number or a symbol as a constituent element, a decoding function for decoding the code received by the reception function, and the decoding. Determination function for determining whether the code decoded by the encoding function is appropriate as data to be processed by a predetermined system, a character, a number or a symbol that can be input as a component of the code, the character, the number or The program includes a program for realizing, by a computer, a definition function that defines a correspondence between a symbol and a character, a number, or a symbol that may be erroneously input, and the decoding function is based on the correspondence defined by the definition function. It is characterized by a function of performing decoding so as to correct an input error.

The decoding function may be a function of correcting an input error by decoding characters, numbers or symbols which are associated with each other by the definition function into the same data. Alternatively, when the decoding function determines that the decoded code is inappropriate as the data to be processed by the predetermined system, the decoding function is at least part of the constituent elements of the code. May be replaced with a letter, number or symbol associated with the constituent element by the definition function, and then the code may be decoded again.

The definition of "can be entered by mistake" is as follows:
It is defined by defining means and defining function. For example, the letters,
The correspondence is defined as a relationship in which a numeral or a symbol and a character, a character, a numeral, or a symbol having a shape similar to that of the number or the symbol when displayed on the screen can be erroneously input. Also, letters, numbers or symbols and their letters,
The numbers or symbols may be associated with the letters, numbers or symbols that are similar in shape when handwritten. Moreover,
The letters, numbers or symbols may be associated with the letters, numbers or symbols that sound similar to the letters, numbers or symbols when read aloud.

A recording medium of the present invention is a recording medium in which the input acceptance program of the present invention is recorded.

The hardware configuration described above is merely the minimum configuration required to implement the present invention.
Further, it is apparent to those skilled in the art that the object of the present invention can be achieved by a similar configuration. For example, mobile phone 3
Is just an example of a terminal for applying a play result to the server 2 by inputting a password, and needless to say, the personal computer 4 described above, a mobile information processing terminal such as a PDA, or a portable game device may be used. Nor.

In the present embodiment, the game targeted by the internet ranking service is a type of game in which the player controls the movement of the character in the game space. The character controlled by the player digs forward while moving the blocks accumulated in the game space with a drill, moving from left to right in principle and moving left and right as necessary. A plurality of characters having different characteristics and abilities are defined, and the difficulty level of the game changes depending on the character used. In addition, there are two types of competitions, one that competes for digging depth (mission driller) and the other that competes for the time required for digging (time attack driller), and multiple spatial layouts (block layout, etc.) are defined for each competition. Has been done. The difficulty level of the game also changes depending on the type of competition and the spatial layout. The score is added not only by the depth of the dug and the time taken for the dug, but also by other factors. Ranking is determined by both the depth or time dug and the score earned.

The program for controlling this game is provided as game software for the game machine 5.
The player is a character used in the game screen,
Play the game by selecting the competition, stage, etc. When the play ends, the digging depth or the time required for digging and the score are displayed on the play result display screen. The play result displayed here is stored in the memory card 28 set in the game device 5.

Further, the player can confirm the best record of the play performed in the past on the best record display screen which can be called from the initial menu. The best record can be confirmed for each competition and each spatial layout. 3A, 3B, and 3C are diagrams showing the best record display screen in the present embodiment. When the best record display screen is called, a competition selection screen as shown in FIG. 3A is first displayed, so that the player selects one competition. FIG. 3A shows a case where the player selects the mission driller as the competition. When a competition is selected, a space layout (stage) selection screen is displayed next. FIG. 3B shows a case where the player selects the Indian stage from the five stages as the spatial layout. When one stage is selected on the spatial layout selection screen, the memory card 2
The best record obtained by sorting the results stored in 8 and the password 31 for applying the best record to the server 2 are displayed. FIG. 3C shows a screen on which the best record of the player's Indian stage is displayed. In the present embodiment, the best record means a play result in which the digging depth is the deepest or the digging time is the shortest. However, when there are two or more such play results, the play result with the highest score among them is the best record.

The password 31 is a competition type, a stage,
40-bit information representing the best record such as characters used, dug depth, and score is converted into an 8-character Hiragana code. That is, each character forming the password is a code of 5-bit data.

In this embodiment, encoding is performed according to the encoding rule shown in FIG. As shown in the figure, the password uses 32 characters that are unlikely to be misidentified when displayed, and the possibility of misidentification is relatively low, such as "ne", "re", and "wa". High characters are not used as password characters. However, the number of characters used for the password depends on the input function of the mobile phone 3 and the hiragana 1
It may be determined according to the number of bits of data to be encoded into characters, and is not particularly limited.

The player uses the mobile phone 3 to access the server 2
You can apply for the best record by accessing to and entering this password on the predetermined screen. The procedure for applying the best record to the server 2 and the processing on the server side for that purpose will be described below.

FIG. 5A is a view showing the best record application screen displayed on the screen 18 of the mobile phone 3. As shown in this figure, in the present embodiment, a comment 32 can be input in addition to the best record application password 31. The comment 32 input here is published together with the ranking.

Further, in the present embodiment, as soon as the best record is applied on the best record application screen, the best record is sorted in the server 2 and the ranking of the player is determined. Further, depending on the order, a message as shown in FIG. 5B, for example, is displayed. This message is generated by embedding the player's name in a predetermined part of a standard message defined for each rank.

FIG. 6 is a flowchart showing the processing of the server 2 described above. As shown in the figure, the player selects the best record application password 3 on the best record application screen.
If you enter 1, the program on server 2
At 101, this password is decrypted to obtain information such as the competition type, stage, character, dug depth, and score.

Next, in step S102, the stored best record data is acquired from the hard disk 11, and in step S103, the best record is sorted to determine the ranking. Further, in step S104, a message corresponding to the determined rank is selected from among a plurality of types of predefined messages, and the message shown in FIG.
As shown in (b), the player's name is entered in a predetermined portion of the message and the message is transmitted to the mobile phone 3. Step S1
In 05, the password decrypted in step S101 and the rank determined in step S104 are stored in the hard disk 11.

The input acceptance process of step S101 will be described in more detail below. In the present embodiment, the password decryption program executed on the server 2 includes characters, numbers or symbols that can be input by the standard input function of the mobile phone 3, and each character, number or symbol. Characters that may be entered incorrectly,
The definition of the correspondence with numbers and symbols is stored in the program. However, the definition may be defined in a predetermined definition file, and the decryption program may decrypt the file by reading the file.

As a possible input error, first, since the shapes such as characters when displayed on the screen are similar,
It is assumed that the player mistakenly makes a note at the stage of making a note of the password, and the incorrect character or the like is input. "A" and "O", "Chi" and "Ra", "Me" and "Nu", "Ha" and "Ho", "Ru" and "Roh", etc. It is also assumed that the player makes a mistake when looking at the memo when inputting the password because the shapes when handwritten are similar. "I" and "ri", "ku" and "shi", "ni" and "ko", etc. can be considered. Further, it may be assumed that the pronunciation is similar when read aloud, so that an erroneous listening occurs when transmitted by voice, and as a result, an erroneous character or the like is input. The definition of the association does not necessarily have to be one-to-one, and three or more characters that may be mistaken for each other may be associated. Further, although only hiragana is used as the password character in the present embodiment, when katakana, alphanumeric characters, symbols, etc. are used, similarly, it is sufficient to associate those which are easily error-prone.

FIG. 7 is a flow chart showing details of the processing in step S101. First, step S20
Accept password input in 1, then step S
At 202, the password is decrypted based on the defined association. FIG. 8 is a diagram showing a decoding method. In the present embodiment, as shown in FIG. 8, characters associated as characters that may be erroneously input are decoded into the same data. For example, as shown in the figure,
“A” and “O” are defined as characters that are easily misidentified when displayed on the screen.
It is encoded as "0". Then, in step S203, it is determined whether or not the data "00000" is valid, and if it is valid, the processes in and after step S102 of FIG. 6 are executed. On the other hand, if the encoded data is invalid, an error message such as "The password is incorrect" is output in step S204,
The process ends. That is, the application for the best record will be rejected.

Alternatively, the password acceptance process of step S101 may be a process as shown in the flowchart of FIG. In the process of FIG. 9, the password received in step S301 is decrypted in step S302 in the reverse procedure of the time when it was encoded, that is, in the conventional procedure that has been conventionally performed. As a result of determining the data obtained by the decryption in step S303, when it is determined that the data is not appropriate as data to be processed by the system, the process returns to step S302 again, and a part of the characters forming the password is After replacing the characters, decrypt the password after replacing the characters.

The replacement of characters in step S302 is performed based on the definition of correspondence as described above. Specifically, check the password characters in order from the beginning,
When a character for which the correspondence of erroneous input characters is defined is found, that character is replaced with the character associated by the definition. If decoding is performed again after performing such preprocessing, there is a high possibility that the code decoded in the determination in step S303 will be determined to be appropriate. If it is determined in step S303 that the data is still inappropriate, the characters after the replaced character are further checked, and the same process is repeated for other characters. Even if all the replacement patterns are tried, if the data is still judged to be inappropriate in step S303, an error message is output and the process is terminated (not shown).

Note that the decoding in step S202 of FIG. 7 or step S302 of FIG. 9 does not necessarily have to be performed for all input characters. For example,
2. Description of the Related Art Conventionally, a password called in the field of games includes a combination of meaningful characters and characters obtained by encoding. For example, there is a game in which a character string consisting of 12 characters, the first 4 characters being the name of the player and the other 8 characters being the character encoding the play result, is called a password. In such a case, the target of the decoding process is 8 characters excluding the first 4 characters.

As shown in FIG. 4, the character "o" is not used in the password in this embodiment. Therefore,
If "O" is entered as one of the characters that make up the password, it is an erroneous entry. In the conventional system, in such a case, a password error occurs and the application for the best record is rejected. However, according to the present embodiment, even if "O" is input, the step S
At the decoding stage of 202, it is interpreted as the same data as "A". Alternatively, in the case of following the flow shown in FIG. 9, since “o” is replaced with “a” in the preprocessing stage of the decryption in step S302, step S is performed.
In the re-determination in 303, it is determined that the password is appropriate. That is, in any of the flows, the input error is automatically corrected in the decoding process.

As described above, according to the present embodiment, even if the player memorizes and inputs an incorrect password, the error is transmitted to the system side.
If it is defined in advance, no password error will occur. For this reason, the player can enjoy the benefit of the ranking service without wasting the high score that has been put out by a small mistake such as a mistaken reading or listening of the password.

Further, the service provider can also provide a more kind service to the user without impairing the conventional advantage that the unauthorized application can be prevented by transmitting the information by the password. Since the definition of the association is not necessarily defined uniformly, it is possible to differentiate the service by the definition method. For example,
The above embodiment is an example assuming a case where an incorrect character or the like is input as an erroneous input. However, in addition to this, an erroneous input such as omission of input or excessive input may occur.
For example, there is an input error such that only 7 characters are input for a password of 8 characters or 9 characters are input. In this case, the insufficient portion (8th character) is associated with a predetermined character or the like in advance, and when only 7 characters are input, the processing is performed assuming that the predetermined character is input as the 8th character. You can do this. Alternatively, when 9 characters are input, the 9th character may be treated as a blank and processed. That is, it is possible to assign a blank character or a control symbol indicating the end of input as a character, number, or symbol that can be erroneously input. Note that possible input errors are expected to differ depending on the device used to enter the password and the age group of the user.
By more accurately grasping the situation of the user, the user interface for receiving the password input can be made more preferable.

In the above embodiment, the server 2 has a function as an input receiving device of the present invention, and the input receiving program of the present invention is one of the programs incorporated in the server 2. In addition to this, for example, a mode in which a dedicated input reception device is installed separately from the server 2 and the decrypted data is transferred to the server 2 is also conceivable.

The present invention can be applied not only to the play result application password of the ranking service but also to any game or service including a password for saving the progress of the role playing game. Further, the present invention can be applied not only to the field of games but also to any field using a method of encoding, storing and transmitting data.

[0046]

According to the input receiving apparatus, the program and the recording medium of the present invention, characters, numbers or symbols that can be input as constituent elements of a code and characters that may be erroneously input as those characters, etc. Since the input code is decoded in consideration of the defined correspondence, if the error is a predefined error, Automatically corrected,
Input is accepted. Therefore, it is possible to avoid the problem that the system cannot be used because the input is rejected by a small mistake when the code is reserved.
