Description

  The present invention relates to an erroneous operation determination system that determines whether a user has erroneously operated a key such as a keyboard.

Conventionally, as a method of determining whether or not there is an error in the operation of the user by the user, the user's operation is monitored. It was determined that the operation was incorrect. And the operation assistance method which estimates the function which a user desires and displays guidance when an erroneous operation is detected is disclosed (for example, refer to patent documents 1).
JP 2003-345487 A (page 5, paragraph number [0030])

  According to Patent Document 1, whether or not an operation is erroneous is determined as an erroneous operation when an error output is output from the device or when a user's operation interruption is captured. However, when determining that the interruption of the user's operation is an erroneous operation, it is not specifically disclosed what kind of state is the interruption of the operation, and what kind of state is the erroneous operation is very unknown. Met. Furthermore, from the expression “interruption of operation”, it is possible to associate a state in which no other operation has been performed after an operation, but in a program executed by a computer (such as an application program), The state of waiting for the operation being executed to be completed or the transition to the next operation may be made depending on the user's judgment.

  The present invention has been made in view of such a problem, and an object thereof is to provide an erroneous operation determination system capable of determining an erroneous operation of a key operation for starting execution of a function of a program.

An erroneous operation determination system according to the present invention is an erroneous operation determination system that determines an erroneous operation with respect to a key operation for executing a function of a program executed on a computer, and is based on an output signal from an input unit when the key is operated. The operation history data storage means for storing for each key the operation interval time from when the key is operated to the next key operation, and the operation interval time stored in the operation history data storage means, The computer is provided with an erroneous operation determination means for determining whether or not the key operation is an erroneous operation depending on whether or not the erroneous operation reference time is preset for each key.
Therefore, it is possible to determine whether or not the operation is erroneous based on the criteria set for each key. In addition, as a determination criterion, if the operation interval time from the key operation to the next key operation is equal to or less than the determination reference time, the key operation can be determined as an erroneous operation. In other words, immediately after a user operates a key, he or she notices an error in the operation, and when the next key operation is performed, or when the user notices an error due to a screen transition after the key operation, the next key operation is performed. It is possible to detect an erroneous operation such as when an error occurs.

  In addition, the number of erroneous operations determined by the erroneous operation determination unit as an erroneous operation is counted for each key, the number of erroneous operations for each key counted by the erroneous operation count unit, and for each key in advance. When there are one or more erroneous operation number comparison means for comparing the set erroneous operation reference number for each key and one or more keys that have been erroneously operated by the erroneous operation number comparison means more than the erroneous operation reference number, the one or more The message corresponding to the key is selected by the message selection means, the message selection means for selecting the message describing the function of the program from the message database when there is no key that has been erroneously operated more than the reference error number of times. Display means for displaying a message on the display unit

  Further, the operation history data storage means stores operation history data for each user ID, the erroneous operation determination means determines whether or not a key operation is an erroneous operation for each user ID, and the erroneous operation frequency counting means. Counts the number of erroneous operations for each user ID, the number of erroneous operations comparison means compares the number of erroneous operations with the number of erroneous operations for each user ID, and the message selection means includes the user ID The message may be displayed every time.

  The message may be displayed on the display unit when the program is started or when user authentication is completed.

  Further, an erroneous operation user number counting means for counting the number of users for each key operation determined to be an erroneous operation by the erroneous operation determination means, and an erroneous operation user number counted by the erroneous operation user number counting means are preset. When there is one or more keys that cause the number of erroneous operation users to be greater than or equal to the first reference user number by the erroneous operation user number comparison means for comparing the first reference user number and the erroneous operation user number comparison means, You may provide the notification means to notify the information of the above key types.

  An erroneous operation user number counting means for counting the number of users for each key operation determined to be an erroneous operation by the erroneous operation determination means, an erroneous operation user number counted by the erroneous operation user number counting means, and a preset second value When there are one or more keys that cause the number of erroneous operation users to be equal to or greater than the second reference user number by the erroneous operation user number comparison means for comparing the reference user number and the erroneous operation user number comparison means, the one or more You may provide the key input control means which controls that the input of the said key was performed when the key was long-pressed or operated continuously.

  The program may transmit a control signal for controlling one or more other computers based on the key operation.

The erroneous operation determination system according to the present invention as described above determines whether or not the operation interval time from the operation of the key to the next operation of the key is equal to or less than the erroneous operation reference time. Immediately after the operation, it is possible to detect that the operation has been mistaken and the next operation has been performed.
Since the erroneous operation is determined for each key, it can be determined based on different criteria for each key. That is, an erroneous operation can be determined according to the function of the program when the key is operated.

In addition, since the number of erroneous operations is counted for each key, the number of erroneous operations is counted, and the counted number is compared with the erroneous operation reference number set for each key. It can be seen that there is a lack of understanding of key functions. By displaying a message about the function of the key, the user can be urged to understand the function of the key.
On the other hand, if the number of erroneous operations is less than the standard number of erroneous operations, it can be understood that there is a lack of understanding about the general functions of the program, and a message about the functions of the program is displayed to the user. Can promote understanding.

  In addition, since operation history data is stored for each user ID, it is possible to determine an erroneous operation for each user. Therefore, a message suitable for each user can be displayed.

  Further, since the message is displayed at the time of starting the program or after the user authentication, the message can be presented to the user when starting the operation of the program, and the user can be further understood.

  Further, when the number of erroneously operated users obtained by counting the number of erroneous users for each key is compared with the first reference number of users, and there is a key whose number of users is equal to or greater than the first reference number of users, data relating to this key Therefore, it is possible to understand that there is a problem with the key arrangement, and the administrator or the like can obtain useful data when setting the key arrangement with few erroneous operations.

  In addition, when the number of erroneously operated users obtained by counting the number of erroneous users for each key is compared with the second reference user number, and there is a key having a user number equal to or greater than the second reference user number, input of the key is performed. Since the input of the key is made effective only when the mode is changed and long press or continuous press is performed, erroneous operations can be reduced.

  Further, since the program controls a plurality of computers, it becomes easier to determine an erroneous operation of a key related to a function such as locking the plurality of computers by a key operation or displaying image data.

  As an embodiment of the erroneous operation determination system according to the present invention, as shown in FIG. 2, a plurality of client computers (hereinafter referred to as clients) C,... . Then, the server S performs the operation based on the input signal input from the keyboard or the pointing device based on the signal transmitted from the server S to the server S. Etc.) can be controlled. More specifically, the server S and the clients C,..., C are provided with a class support program, and the clients C,. That is, when the “teacher screen transmission” key K5 of the input unit 2 shown in FIG. 3 is pressed (operated), the client C,..., C is controlled so that the screen of the server S is displayed. The operation method of the application program can be explained by operating. The above-described lesson support program is a program used when learning how to use the computer at a school or the like using a computer. In the embodiment, the explanation is based on the lesson support program, but the present invention is not limited to the lesson support program, and may be a program having other fields and functions.

  As shown in FIG. 1, an erroneous operation determination system 1 according to the present invention includes an input unit 3, an operation history data storage unit 4, an erroneous operation determination unit 5, an erroneous operation count unit 6, an erroneous operation count comparison unit 7, a message database 8, and a message. The server S includes a selection unit 9, a display unit 10, an erroneous operation user number counting unit 11, an erroneous operation user number comparison unit 12, a notification unit 13, and a key input control unit 14. The server S is connected with a display unit 15 capable of displaying a message and an input unit 2 as shown in FIG.

As shown in FIG. 3, the input unit 2 includes keys K <b> 1 to K <b> 9 that are used when executing functions provided in the class support program. Normally, when the key K is pressed, only the function of the class support program corresponding to the key is executed.
3 includes a “power ON” key K1, a “power OFF” key K2, a “release” key K3, a “video transmission” key K4, a “teacher screen transmission” key K5, and a “full screen video transmission”. ”Key K 6,“ Confirm ”key K 7,“ Still image reception ”key K 8, and“ Lock ”key K 9 are provided. By pressing these keys K, the function of the class support program is executed.
The input unit 2 shown in FIG. 3 is an input unit separate from a JIS keyboard (a keyboard capable of inputting alphabets, numbers, symbols, etc.) connected to a computer such as a personal computer. Or a touch panel (touch screen) or the like. The key K may be used in combination with a key for inputting characters (key that can input alphabets, numbers, symbols, etc.), but only for executing the function of the class support program as shown in FIG. Can be used to set an error operation reference time, which will be described later, based on the function set for each key.
Further, the input unit 2 is not limited to hardware keys as shown in FIG. 3, but includes keys, buttons and icons (software) displayed on a touch panel (touch screen) or a display screen. Wear key). In other words, the key operation in the present invention is not limited to pressing a hardware key, but pressing (touching) a key (including buttons and icons) displayed on a touch panel (touch screen). And operating keys (including buttons and icons) displayed on the display screen with a pointing device.

  The input means 3 is a means for inputting an output signal from the input unit 2.

  The operation history data storage means 4 stores data such as the key type operated by the user, the operated time, the operation interval time from the key operation to the next key operation, the next operated key type, etc. Is stored as operation history data. When a plurality of users operate (use) the lesson support program, operation history data is stored for each user ID so that a key that is frequently used, a key that is frequently erroneously operated, and the like are known for each user. Also good.

The erroneous operation determination unit 5 determines that the key operation is erroneous depending on whether or not the operation interval time stored in the operation history data storage unit 4 is equal to or less than an erroneous operation reference time preset for each key. It is means for determining whether or not.
For example, immediately after the erroneous operation reference time is set to 10 seconds and the user erroneously presses the “video transmission” key K4 in order to press the “full-screen video transmission” key K6 (see FIG. 3), (10 When the “Release” key K3 is pressed when the error is noticed (within seconds), or by the display state (screen transition) after the “Video transmission” key K4 is pressed (within 10 seconds) When the “release” key K3 is pressed, it is determined that the “video transmission” key K4 is pressed as an erroneous operation. On the other hand, when the user intends to press the “full screen video transmission” key K6 and presses the key K6, the video is displayed on the clients C,..., C, and the time until the video ends (10 seconds or more). Since the next key operation is performed when the time has elapsed, it is determined that the key operation is normal.
When the operation history data storage means 4 stores operation history data for each user ID, it is determined for each user ID whether or not the key operation is an erroneous operation so that the tendency of erroneous operation for each user can be known. May be.

  The erroneous operation number counting means 6 is a means for counting the number of erroneous operations determined by the erroneous operation determination means 5 for each key. When the erroneous operation determination means 5 determines whether or not the key operation is an erroneous operation for each user ID, the number of erroneous operations of each key may be counted for each user ID.

  The erroneous operation frequency comparison means 7 is a means for comparing the erroneous operation frequency for each key counted by the erroneous operation frequency counting means 6 with the erroneous operation reference frequency preset for each key for each key. As the erroneous operation reference frequency, the number set by the administrator may be used, or the erroneous operation frequency data for each key stored in the operation history data storage unit 4 may be used (for example, erroneous operation by all users). The average value of the number of times is calculated for each key, and this is used as the erroneous operation reference number.)

  The message database 8 stores messages about functions executed by the class support program (program) by the key operation in association with the keys. In addition, a message explaining the functions of the overall operation of the lesson support program is also stored.

  The message selection means 9 is a means for selecting a message stored in the message database 8, and when there is one or more keys that have been erroneously operated more than the erroneous operation reference number by the erroneous operation number comparison means 7, Means for selecting a message corresponding to the one or more keys, and selecting a message explaining the function of the program when there is no key that has been erroneously operated more than the erroneous operation reference count; When a plurality of function explanation messages for the general operation of the lesson support program are stored, they may be selected at random. For example, a message relating to one function selected at random from the top 10 functions that are considered to be relatively unoperational from the operation history data stored in the operation history data storage means 4 is selected.

  The display means 10 is a means for displaying the message selected by the message selection means 9 on a display unit 15 such as a display.

  The erroneous operation user count counting means 11 is a means for counting the number of users for each key operation determined to be an erroneous operation by the erroneous operation determination means 5. In other words, the number of users who performed erroneous operations for each key can be known by the means.

  The erroneous operation user number comparing means 12 is a means for comparing the erroneous operation user count counted by the erroneous operation user number counting means 11 with a preset first reference user number and second reference user number. The first reference user number and the second reference user number may be a user number or a user ratio (ratio of the number of erroneous operations with respect to the total number of users) preset by an administrator.

  The notification means 13 notifies the information of the one or more key types when the erroneous operation user number comparison means 12 includes one or more keys with the erroneous operation user count equal to or greater than the first reference user count. Means. The data notified by the notification means 13 includes data such as the key type, the number of erroneous operations, the erroneous operation ratio, and the current key position. The administrator who has received this notification can change the key arrangement with reference to the operation history data and the like to reduce erroneous operations.

  The key input control means 14 changes the input mode of the key when the erroneous operation user number comparison means 12 has one or more keys with the erroneous operation user number equal to or greater than the second reference user number, It is a means for controlling key input. As the input mode, there are a normal mode in a normal key operation state and a control mode in which an effective key input is performed when the key is pressed (or continuously pressed). That is, when there are more than the second reference number of users, it can be seen that there are many users who perform an erroneous operation of the corresponding key. Therefore, when the input mode is changed and long pressing (or continuous pressing) is performed, the erroneous operation of the user can be reduced by enabling the key operation.

  Next, processing of the erroneous operation determination system when operating the lesson support program will be described based on the flowchart shown in FIG.

  First, the lesson support program is activated, and user authentication is performed by inputting a user ID and a password (S1). At this time, if the user ID and password are authentic, the operation history data of the key operation for each user ID is stored in the operation history data storage means 4. On the other hand, when the user ID and the password do not match in the user authentication, the lesson support program is terminated or requested again.

  Next, in order to display the screen of the client C on the display unit of the server S, the user (teacher) intends to press the “still image reception” key K8, but erroneously presses the “lock” key K9 (S2). . The user immediately notices the mistake (for example, after 1 to 2 seconds) and operates the “release” key K3 (S3). On the other hand, based on the output signal output from the input unit by the key operation described above, the operation history data of the key operation described above is stored in the operation history data storage means 4 (S4).

  At this time, it is determined whether or not the operation interval time (time interval) from when the “lock” key K9 is operated to when the “release” key K3 is pressed is equal to or shorter than the erroneous operation reference time (for example, 10 seconds). (S5). As described above, when the “release” key K3 is operated immediately after the “lock” key K9 is operated (when the operation interval time is equal to or less than the erroneous operation reference time), the key operation of the “lock” key K9 is performed. Is determined to be an erroneous operation, and the process proceeds to step 6 (S6) described later (S5).

  On the other hand, in step 2 (S2) and step 3 (S3), when the user presses the “lock” key K9 in order to prevent the keyboard and mouse of the clients C,. Since the “release” key K3 is not pressed (because it is locked for several minutes), the operation interval time becomes longer than the erroneous operation reference time, and it is determined that the key operation is normal and the processing as the erroneous operation determination system is terminated. (S5).

  That is, in the case of an erroneous operation, the operation interval time is about several seconds. However, in a normal operation, the operation interval time is longer than that in the case of an erroneous operation because the client C is locked for several minutes. Therefore, it can be understood that if this operation interval time is shorter than the erroneous operation reference time, it is an erroneous operation, and otherwise it is a normal operation. Furthermore, by setting the erroneous operation reference time for each key, it is possible to accurately determine whether or not there is an erroneous operation for each key.

If it is determined in step 5 (S5) that the key operation is an erroneous operation, the number of users who erroneously operated the key ("lock" key K9) is counted (S6).
Then, it is compared whether or not the number of erroneous operation users is equal to or greater than the first reference user number (S7). That is, if the number of erroneously operated users is greater than or equal to the first reference number of users, whether or not the current key layout is likely to cause an erroneous operation is determined by comparing whether or not many users perform an erroneous operation. It can be one of the determination criteria. Further, if the number of erroneously operated users is less than the first reference number of users, it is considered that there is a low possibility of erroneous operation due to a problem in key arrangement because not many users have performed erroneous operations.

  In step 7 (S7), when the number of erroneously operated users is equal to or greater than the first reference number of users, the key type of the key with many erroneous operators ("lock" key K9), data such as key arrangement is notified to the server S administrator To do. As a notification method, an e-mail is transmitted to an administrator's e-mail address registered in advance or recorded in a log file or the like. In step 7 (S7), when the number of erroneous users is less than the first reference user number, the process proceeds to step 9 (S9).

Further, it is compared whether or not the number of erroneous operation users is equal to or greater than the second reference user number (S9). If the number of erroneous operation users is equal to or greater than the second reference number of users, the process proceeds to step 10 (S10), and if less than that, the process proceeds to step 11 (S11).
If the number of erroneously operated users is greater than or equal to the second reference user number in step 9 (S9), the key input control means changes the input mode of the “lock” key K9 from the normal mode to the control mode and presses and holds it for a long time (For example, when a key for three times the standard time is kept pressed), the input mode is changed to a valid key.
The number of second reference users may be the same number of users as the number of first reference users, but the number of first reference users is a criterion for determining whether there is a problem with key arrangement. Since the second reference user number is a reference for determining whether or not the key input mode is changed, it is preferable to set an optimal reference user number for each reference.

Thereafter, the number of erroneous operations of the user of the “lock” key K9 determined to be an erroneous operation in the step 5 is counted based on the operation history data stored in the operation history data storage means 4 (S11). .
Then, a comparison is made as to whether or not the number of erroneous operations of the “lock” key K9 is equal to or greater than the number of erroneous operations. If the comparison result is greater than or equal to the number of erroneous operations, the process proceeds to step 13 (S13). If so, the process proceeds to step 14 (S14).
Based on the comparison result of step 12 (S12), whether or not the user understands the function of the “lock” key K9 is determined depending on how many times the user has made an erroneous operation regarding the “lock” key K9.

  In step 12 (S12), when the number of erroneous operations is equal to or greater than the number of erroneous operations, a message as shown in FIG. 5A is selected from the message database 8 (S13). On the other hand, when the number of erroneous operations is less than the number of erroneous operations, a message explaining the function of the lesson support program as shown in FIG. 5B is selected from the message database 8 (S14).

  Then, after the user selected when the user logs in next time, the message selected in the step 13 (S13) and the step 14 (S14) is displayed on the display unit 15 as shown in FIG. Displayed so that the user can understand the function of the lesson support program and the function of the “lock” key K9.

  In the above-described embodiment, the “lock” key K9 is described as an example, but other keys may be used as a matter of course. In FIG. 5A, only the message regarding the function of the “lock” key K9 is displayed. However, when a message with a plurality of keys K is selected, a message regarding the functions of the plurality of keys K is displayed. .

  As described above, the time from the key operation to the next key operation is measured for each key, and it is possible to determine whether or not the operation is erroneous based on the measured operation interval time. Further, based on the determination of an erroneous operation, a message can be displayed to the user to facilitate understanding of the function of the program. Furthermore, it is possible to notify the administrator that the key arrangement is improved based on the number of erroneously operated users so as to reduce the erroneous operation, or change the key input mode to reduce the erroneous operation of the user.
