Description

  The present invention relates to an information display apparatus and method for displaying information representing an operation performed on an apparatus.

  Devices such as POS (Point Of Sale) terminals, ATM (automated teller machines), or vending machines are operated by operators such as employees or users. An operator may perform an incorrect operation or an illegal operation, and a failure may occur in the apparatus due to the operation. In order to investigate the cause of the failure that has occurred, the operator may be asked to confirm the operating procedure. It is extremely difficult to grasp. Therefore, it is necessary to examine all possible operation procedures, and it takes a lot of time to investigate the cause.

  In order to investigate the cause in a short time, there is a device that makes it possible to accurately grasp the operation performed on the device by storing and displaying a history of operations and the like. For example, as a first conventional technique, there is a user operation log visualization device that can specify a position of a video clicked by the user from a user click operation log for the video. The user operation log visualization device reproduces a video that the user has performed a click operation, and the click position indicated by the log data in the video of the reproduction time indicated by the log data of the click operation performed by the user on the video. A mark indicating that is superimposed and displayed (for example, see Patent Document 1).

  As a second conventional technique, there is a failure analysis support device that can reproduce an operation performed by a user in order to investigate the cause of a failure. This failure analysis support device records a user's operation history and a history such as display on the operation panel, and automatically checks the operation input from the user on the operation panel when investigating the cause of the failure that occurred. (For example, see Patent Document 2).

  As a third conventional technique, there is a plant control monitoring device that executes a plant operation control operation by a touch operation on a screen of a display device. This plant control monitoring device stores the type of screen on which a touch operation is performed, the touch coordinates of the screen, the time, and the content of the operation, so that the performed operation can be reproduced on the screen (for example, a patent) Reference 3).

  As a fourth conventional technique, there is a recording / reproducing apparatus. This recording / reproducing apparatus reproduces the operation up to the occurrence of an error including the operation timing by storing the operated content in the memory including the operation continuation time (for example, Patent Document 4). reference).

  As a fifth conventional technique, there is a failure analysis support apparatus that can analyze a failure of a computer system, particularly an application. This failure analysis support apparatus records the operation procedure of an application as a log file in the customer side system, and reproduces the operation procedure in the development side system based on the recorded log file. Information recorded in the log file includes screen data, user operation, processing history, and processing time (see, for example, Patent Document 5).

When a log target operation occurs, a log of the log target operation is generated, and the generated log is stored in the log file unit T15. Further, when a log target log instruction set in the log setting unit 124 is received from the input / output unit 11 or the display control unit 16, a log based on the log instruction is generated and stored in the log file unit T15. Whether to store in a standard log file or a specified log file in the log file unit T15 is determined based on the setting of the log setting unit 124.

  FIG. 5 is a diagram illustrating a log instruction example 52 notified from the input / output unit 11 or the display control unit 16 illustrated in FIG. 3 to the log generation unit 121. The log instruction basically indicates one log instruction per line, and FIG. 5 shows six log instructions. One log instruction is composed of a plurality of numerical values or character strings separated by commas. The first numerical value indicates an input / output unit number described later in FIG. 6, the second numerical value indicates an operation number described later in FIG. 7, and the third numerical value or character string is the details of the operation.

  For example, in the log instruction “1, 1, 142, 244” on the first line, the operation of the operation number “1”, that is, the “touch” operation occurs at the input / output number “1”, that is, the touch panel unit 111, “142,244”, that is, the touched position is the coordinates (142,244). The log instruction on the second line is “1, 2, 145, 242”, the log instruction on the third line is “11, 11, 01F45CCD4EF10E042”, and the log instruction on the fourth line is “21, 31, 130”. The log instruction on the fifth line is “1,1,582,289”, and the log instruction on the sixth line is “1,2,573,295”. The operation unit specifying information for specifying the operation unit such as an operated key is information representing a coordinate position, for example.

  FIG. 6 is a diagram showing the input / output unit name definition table 53 stored in the character string conversion table unit T122 shown in FIG. The input / output part name definition table 53 is a table indicating a corresponding “input / output part name log character string” for each “input / output part number” for specifying the input / output part. As a remark on the right side of the input / output part name definition table 53, the input / output part names are described. Since the character string in the input / output unit name log character string column of the table can be set arbitrarily, the input / output unit name log character string may be set to a character string that has nothing to do with it.

  For example, the input / output unit number “001” indicates that the input / output unit name log character string is “operation” and the remarks are “touch panel”, that is, the touch panel unit 111. Similarly, the input / output unit name log character string and the remarks for the input / output unit number are “011” for “serial1”, that is, the serial communication unit 1, and “012” for “serial2”. That is, the serial communication unit 2, “013” is “extserial”, that is, serial communication unit 3, “021” is “display”, that is, the display unit, and “031” is ““ Sslan ””, that is, an SS-LAN communication unit, and “100” is ““ core ””, that is, an application.

  “Serial communication unit 1”, “Serial communication unit 2”, and “Serial communication unit 3” are all serial communication units 116, and show a case where a plurality of input / output channels are used in the same device. . An input / output unit number is assigned to each of a plurality of input / output channels to distinguish them.

  FIG. 7 is a diagram showing the action name definition table 54 stored in the character string conversion table unit T122 shown in FIG. The action name definition table 54 is a table indicating a corresponding “action name log character string” for each “action number” for specifying an action. On the right side of the action name definition table 54, each action name is described as “Remarks: Corresponding action”. Since the character string in the action name log character string column of the table can be arbitrarily set, the action name log character string may be set to a character string that is completely unrelated.

  For example, the operation number “000” indicates that the operation name log character string is “message” and is information. Similarly, the action name log character string and the remarks for the action number are “pressed” for “001”, that is, “touched” for “001”, and “released” for “002”, that is, “011”. "" Read "or input," 012 "is" write "or output," 021 "is" error "or error, and" 031 " "" Change "", that is, a screen change.

  FIG. 8 is a diagram showing an operation detail creation rule table 55 stored in the character string conversion table unit T122 shown in FIG. The operation detail creation rule table 55 is a table showing “operation details log creation rule” for each combination of “input / output unit” and “operation”. The meaning of each combination is described as “Remarks: Meaning” on the right side of the operation detail creation rule table 55.

  For example, the combination of the input / output unit “001” and the operation “001” means that the touch panel has been touched, and the log creation rule of the operation details indicates that “the third and fourth arguments have coordinates“ x =% 04d, This means that “y =% 04d“ form ”is performed”. Similarly, the log creation rule and remarks of the operation details for each combination of the input / output unit and the operation means that the touch panel is released for the combination of the input / output unit “001” and the operation “002”, For the combination of the input / output unit “011” and the operation “011” in which “the third and fourth arguments are in the format of coordinates“ x =% 04d, y =% 04d ””, the serial communication unit 1 This means input, and for the combination of the input / output unit “011” and the operation “012” in which the third argument is converted to a hexadecimal number, the serial communication unit 1 means output, and “ For the combination of the input / output unit “011” and the operation “021” that has been “hexadecimal”, this means an error in the serial communication unit 1 and “the third argument is made decimal” is there.

  The combination of the input / output unit “021” and the operation “031” means a screen change in the display unit, and the input / output unit “031” in which the “third argument is set to“ display =% 04d ”format” is performed. ”And the operation“ 011 ”means an input in the SS-LAN communication unit, and the input / output unit“ 031 ”and the operation“ 012 ”that have performed“ the third argument in hexadecimal ”are performed. For the combination, it means output in the SS-LAN communication unit, and for the combination of the input / output unit “100” and the operation “000” performed “make the third argument a hexadecimal number”, it means application information. Then, “output the third argument as characters” was performed.

When the log generation unit 121 receives the log target log instruction set in the log setting unit 124 from the input / output unit 11 or the display control unit 16, the log generation unit 121 first acquires the date and time from the system timer unit 13 and represents the date and time. Generate date and time log string. Next, based on the first numerical value of the received log instruction, the input / output unit name log character string from the input / output unit name definition table 53 shown in FIG. 6 and the second numerical value are shown in FIG. The action name log character string is acquired from the action name definition table 54. Further, based on the first numerical value, the second numerical value, and the third and subsequent numerical values or character strings of the received log instruction, the operation detail creation rule table 55 shown in FIG.
An operation detail log representing the details of the operation is created according to the operation detail log creation rule. The acquired date / time log character string, input / output unit name log character string, operation name log character string, and created operation detail log are combined to generate a log corresponding to the log instruction. The generated log is stored in the log file unit T15.

  For example, when generating a log indicating that the operator has touched the touch panel, the instruction log is the instruction log “1, 1, 142, 244” on the first line of the instruction log example 52 illustrated in FIG. FIG. 8 shows combinations of the number “001” representing the input / output unit “touch panel” indicated by the first argument “1” and the number “001” representing the operation “touch” indicated by the second argument “1”. Referring to the operation detail creation rule table 55, the operation detail log creation rule “the third and fourth arguments are in the format of coordinates“ x =% 04d, y =% 04d ”” is obtained. Here, “% 04d” indicates a 4-digit decimal number, and is an example of a standard output format related to character output in a program using C language. Assuming that the date and time is 15: 15: 01.120 seconds on May 18, 2006, from the third argument “142” and the fourth argument “244”, the log is “2006/05/18, 15:05:01. 120, “operation”, “pressed”, “x = 00142, y = 0244”.

  FIG. 9 is a diagram illustrating a log example 56 stored in the log file unit T15 illustrated in FIG. The log example 56 basically shows one log for one line, that is, a log for one operation on the target machine 10, and FIG. 9 shows six logs. One log is composed of a plurality of numerical values or character strings separated by commas. The first numeric value or character string is the date and time when the operation to be logged occurred, the second numeric value or character string is the input / output part name, the third numeric value or character string is the operation name, the fourth numeric value or character string These are the operation details which show the content of each operation | movement in detail. In the example shown in FIG. 9, four items are exemplified, but in addition to these, information related to the target machine 10 such as a related program name, a user name, the number of characters of the log, or a machine name in the log, and a use situation Or you may include the information etc. which specify a place. Furthermore, when the information amount of one log increases, the log may be divided into two or more lines.

  FIG. 9 shows a log example 56 corresponding to the instruction log example 52 shown in FIG. The first line is “2006/05/18, 15: 05: 01.120,“ operation ”,“ pressed ”,“ x = 00142, y = 0244 ””, and the second line is “ 2006/05/18, 15:05: 01.541, “operation”, “released”, “x = 0145, y = 0242” ”. The third line is“ 2006/05/18, 15 : 05: 02.951, “serial1”, “read”, “01F45CCD4EF10E042”, and in the fourth line, “2006/05/18, 15: 05: 04.092,“ display ”,“ change ” ”,“ Display = 0130 ”” and the fifth line contains “2006/05/18, 15: 05: 08.735,“ operation ”. , “Pressed”, “x = 0582, y = 0289” ”, and the sixth line contains“ 2006/05/18, 15: 05: 09.090, “operation”, “released”, “x = 0573, y = 0295 "".

  In the example shown in FIG. 9, an example in which information specifying the date and time is included in the log is shown, but when the information for specifying the date and time is not included in the log, the log is recorded in the log file of the log file unit T15 In this case, the log is stored in the order in which the logs were generated or in the order in which the operations to be logged occurred. When information for specifying the date and time is included in the log, the order may be arbitrary.

  FIG. 10 is a diagram showing a log event conversion table 57 used by the application unit 14 shown in FIG. 3 to create a log instruction. The log event conversion table 57 is a table indicating a “log character string” corresponding to each “event” generated in the application control unit 142. In the log character string column, an arbitrary log character string can be set according to the event. Therefore, the application can be recorded as a log independent of the input / output unit 11, that is, only the application information can be recorded as a log.

  FIG. 10 shows the log character string ““ Program A start ”” for the event “Start of program A”, and the log character string ““ Program A end (end code =%) for the event “End of program A” ”. 03d) "" is displayed, the log character string "" employee code =% 06d "" is displayed for the event "designation of employee to operate", and the log character string "" is specified for the event "start of checkout process" Checkout process start "" is shown.

For example, when the target machine 10 is a terminal used in a restaurant composed of a plurality of employees, in order to identify the operator of the terminal, the application uses the employee information, for example, the employee code to identify the employee. to manage. The operation of the touch panel is an operation related to the employee who uses the terminal, and there is a case where the input / output operation performed on the touch panel and the employee information are associated with each other and recorded in a log. When the log recording control unit 12 is not configured to know the employee information, the application control unit 142 records information that exists only in the application, for example, employee information as an arbitrary character string in order to record in the log. The log generation unit 121 is instructed by a log instruction.

  Each log instruction shown in the log instruction example 58 includes a plurality of numerical values or character strings separated by commas, as in the example shown in FIG. The first numerical value indicates the input / output unit number shown in FIG. 6, the second numerical value indicates the operation number shown in FIG. 7, and the third numerical value and the character string are details of the operation. The details of the operation are information corresponding to the event shown in FIG. For example, the log instruction “100, 0,“ Program A start ”” on the first line is an input / output number “100”, that is, an application, generates an operation with an operation number “0”, that is, “information”. “Program A started”, that is, program A has started. The log instruction on the second line is “100, 0,“ employee code =% 06d ”, 138”, and the log instruction on the third line is “100,0,“ program A end (end code =% 03d) ”. , 0 ".

  Each log shown in the log example 59 is a log corresponding to the log instruction shown in the log instruction example 58. Similarly to the example shown in FIG. 9, a plurality of numerical values or character strings separated by commas are used. Composed. The first numeric value or character string is the date and time when the operation to be logged occurred, the second numeric value or character string is the input / output part name, the third numeric value or character string is the operation name, the fourth numeric value or character string These are the operation details which show the content of each operation | movement in detail. For example, “2006/05/26, 10: 13: 59.022,“ core ”,“ message ”,“ Program A start ”” is indicated on the first line, and “2006/05” is indicated on the second line. 05/26, 10: 14: 21.924, “core”, “message”, “employee code = 000138” ”is shown on the third line,“ 2006/05/26, 10:20:11 311, “core”, “message”, “program A end (end code = 000)”.

  FIG. 16 is a diagram schematically illustrating an example of a procedure for generating the playback screen 70 displayed on the screen display unit 71 illustrated in FIG. 13. The log reproduction control unit 28 uses the screen table 61 shown in FIG. 15 and the target machine 10 displayed when the log is recorded from the log of the log file read from the target machine 10 into the buffer unit 22. Derive the screen above.

  FIG. 16 shows a log file 15a, a screen image file database 24a, a reproduction image 70a, and a reproduction image 70b. The log file 15a includes two logs “2006/05/22, 14: 49: 42.789,“ display ”,“ change ”,“ display = screen 0001 ”” and “2006/05/22, 14:53. : 02.024, “display”, “change”, “display = screen 0002” ”are recorded. The screen image file database 24a stores a screen table 61, a screen image “0001.PNG”, a screen image “0002.GIF”, and a screen image “0003.JPG”.

  For example, when the log analysis unit 23 analyzes the first log of the log file 15 a read into the buffer unit 22, the log reproduction control unit 28 displays “screen on May 22, 2006 at 14: 49: 42.789”. It becomes clear that “0001” is displayed. The screen image file database 24a is searched using the screen information “screen 0001” as a key to obtain a related screen image file name “0001. PNG”. That is, it is derived that the screen displayed on the target device 10 at the time of log recording is an image of the file “0001.PNG”. The log reproduction control unit 28 acquires the image image having the screen image file name “0001.PNG” from the screen image file database 24a, and displays it on the display unit S25 as the reproduction image 70a. Similarly, the reproduction image 70b is displayed on the display unit S25 for the second log.

  The reproduction image 70a is an image image “screen 0001” displayed on the display unit T113 of the target device 10 at “14: 49: 42.789 seconds on May 22, 2006”, and the reproduction image 70b is “2006 This is the image “screen 0002” displayed on the display unit T113 of the target machine 10 on May 22, 14: 53: 02.024 ”.

  FIG. 17 is a diagram showing an example of another screen table 62 stored in the screen image file DB 24 shown in FIG. The screen table 62 includes screen information defined by information for specifying the background of the screen or information for specifying a window as a part, and a screen image file name for specifying a file for storing the screen image. As in the screen table 61 shown in FIG. 15, the table displayed at the time of log recording is specified from the log and used to generate a reproduction image. The screen image file name is a name of a file determined in advance for each screen image. In the file indicated by the screen image file name, a screen background displayed on the target machine 10 or a part such as a window, button, or text is displayed. The same or equivalent image is recorded.

  In FIG. 17, “B0001.PNG” is shown as the screen image file of the screen information “background 0001”, “B0002.PNG” is shown as the screen image file of the screen information “background 0002”, and the screen information “background 0003” is shown. "B0003.PNG" is shown as the screen image file of "", "W0001.PNG" is shown as the screen image file of the screen information "window 0001", and "W0002.PNG" is shown as the screen image file of the screen information "window 0002". "It is shown.

  The screen table 62 is different from the screen table 61 shown in FIG. 15 in that the image file indicated by the image file name in the screen table 62 is a component indicating a part of the entire image image displayed on the screen. It is where you are. The reproduction image is generated by combining the image image used as the background and the image image of the window displayed in front of the background. That is, a plurality of image images obtained from a plurality of screen information recorded in a log are superimposed. Therefore, since image images can be used in common, the number of image images stored in the screen image file database 24 can be reduced or the data size of each data can be reduced.

  FIG. 18 is a diagram schematically illustrating another example of a procedure for generating a playback screen displayed on the screen display unit 71 illustrated in FIG. 13.

Using the screen information “background 0001” as a key, a search is performed in the screen image file database 24b to obtain a related screen image file name “B0001.PNG”. Similarly, the screen information “window 0001” is searched as a key to obtain the screen image file name “W0001.PNG”. The log reproduction control unit 28 acquires the image image with the screen image file name “B0001.PNG” and the image image with the screen image file name “W0001.PNG” from the screen image file database 24b, and obtains two image images. The screen is superimposed and displayed on the display unit S25 as a playback image 70c, and the screen displayed on the target machine during the log recording is played back. Similarly, the reproduction image 70d is displayed on the display unit S25 for the second log.

  The reproduction image 70c is the image image “background 0001” and “window 0001” displayed on the display unit T113 of the target device 10 at “14: 49: 42.789 seconds on May 22, 2006”, and the reproduction image 70d. Are the image images “background 0001” and “window 0002” displayed on the display unit T113 of the target machine 10 at “14: 53: 02.024 seconds on May 22, 2006”.

When the log is a screen display, as shown in FIG. 16 or FIG. 18, the screen number corresponding to the operation details of the log is acquired from the screen image file DB 24, and the acquired display screen is displayed in the display unit S25. Display playback.

  Further, in the case of an operation log for the touch panel unit 111 or the key unit 112, the position indicated by the operation details of the log is specified and indicated by a pointer, whereby the operation button or key in the screen image displayed on the display unit S25 is displayed. Among them, the operated operation button or key can be indicated. When performing the next operation after performing one operation, the afterimage of the pointer is sequentially moved from the position of one operation to the position of the next operation on the path connecting the position of one operation and the position of the next operation. By making them display, it is possible to track the movement of the pointer.

  FIG. 22 is a diagram showing a schematic configuration of a log display system 2 which is another embodiment of the present invention. The log display system 2 that is an information display device stores a log file in a storage device outside the target machine, and includes a target machine 10 a, a support machine 20, and a network disk 40 that are respectively connected via a LAN 30. The information display method is processed by the log display system 2. The support machine 20 is the same as the support machine 20 shown in FIG. 3, and is not shown. The target machine 10a is obtained by eliminating the log file portion T15 of the target machine 10 shown in FIG. The log transmission unit 18 is the same as the LAN communication unit 114 shown in FIG. 3 and transmits the log generated by the log generation unit 121 to a network disk 40 connected to a network such as the LAN 30 or a public line.

  The network disk 40 is connected to the LAN 30 and includes a log file unit N41 and a log communication unit N42. The log file unit N41 is configured by a storage device such as a hard disk device, for example, and stores the log received by the log communication unit N42 from the target machine 10a. The log communication unit N42 is a communication unit that transmits and receives data to and from other devices connected to the LAN 30, such as the target device 10a and the support device 20. Thus, log recording can be performed without providing a storage area in the target machine 10a.

  FIG. 23 is a diagram showing a schematic configuration of a log display system 3 which is still another embodiment of the present invention. The log display system 3 that is an information display device is a system that eliminates a log file, and includes a target machine 10b and a support machine 20a that are respectively connected by a LAN 30. The information display method is processed by the log display system 3. The target machine 10b is the same as the target machine 10a shown in FIG. As will be described in detail with reference to FIG. 28, the support device 20a is provided with a log receiving unit S29 instead of the log reading unit 21 and the buffer unit 22 of the support device 20 shown in FIG. The target device 10b transmits the generated log to the support device 20a by the log transmission unit 18 without storing the generated log.

  FIG. 24 is a block diagram showing an example of the configuration of the support machine 20a shown in FIG. The support machine 20a includes a log receiving unit S29 instead of the log reading unit 21 and the buffer unit 22 of the support machine 20 illustrated in FIG. The log receiver S29 of the support machine 20a receives the log transmitted from the target machine 10b and sends it to the log analyzer 23. The log analysis unit 23 analyzes the log received from the log reception unit S29 and sends the analysis result to the log reproduction control unit 28. The log reproduction control unit 28 performs display based on the analysis result received from the log analysis unit 23. That is, the log display system 3 can display the operation performed on the target machine 10b on the display unit S25 of the support machine 20a in real time. Therefore, it is possible to monitor the operation of the target machine 10b at a location away from the target machine 10b. It becomes easy to use for the purpose of monitoring logs.

  FIG. 25 is a diagram showing an example of a first password input screen 75 displayed on the display unit T113 shown in FIG. The password input screen 75 is a screen displayed by the application unit 14. The personal identification number input screen 75 is a screen for inputting a personal identification number by touching the portion of the touch panel unit 111 corresponding to the numeric operation buttons displayed on the personal identification number input screen 75. The personal identification number input screen 75 includes an operation button display unit 76 that displays numeric operation buttons, a message unit 77 that displays messages, and an input display unit 78 that displays input numbers. In FIG. 25, numeric operation buttons “0” to “9” (hereinafter, numeric operation buttons are also referred to as “numeric buttons”) are displayed on the operation button display unit 76, and “password” is displayed on the message unit 77. The message “Please input” is displayed, and “***” is displayed on the input display section 78. “* (Asterisk)” indicates that a number has been input, but masked in order not to disclose the input number. The replacement information is information for replacing the operation unit specifying information. More specifically, the replacement information is information different from the number that is the information indicated by the operation unit specifying information, and is, for example, “*”.

  When storing the operated numeric operation buttons as a log, the position in the touch panel unit 111 touched by the user to operate the numeric operation buttons is stored instead of storing the numeric value indicated by the operation button, for example, XY Stores the position expressed in coordinates. Therefore, when the log is reproduced, the operated operation button can be identified from the operation buttons displayed on the screen based on the position stored as the log. That is, if the displayed screen and the position in the touch panel unit 111 touched by the user can be specified, the operated operation button can be known and the personal identification number can be specified.

  FIG. 26 is a diagram showing an example of the log exclusion designation table 66 stored in the log reproduction setting file unit 82 shown in FIG. The log exclusion designation table 66 is a table in which conditions for excluding log reproduction when the log reproduction control unit 28 reproduces a log and displays it on the display unit T113 are set by the log reproduction setting unit 81. .

  The example of the log exclusion designation table 66 shown in FIG. 26 includes items of “image number”, “data”, and “log exclusion designation”, and “data” and “log exclusion designation” for each “image number”. Is set. “Image number” and “data” have the same contents as “display image number” and “data” in the image management table 51 shown in FIG. 4, respectively, and “log exclusion designation” excludes log reproduction. If an object, for example, a device is set and the device is the touch panel unit 111, an area can also be set.

  In the example of the log exclusion designation table 66 shown in FIG. 26, for the image number “0001”, data “start image data” and log exclusion designation “touch panel: none” are indicated, and the image data of the image number “0001” is displayed. When “start image data” is displayed, the log reproduction of all operations on the touch panel unit 111 is performed. For the image number “0002”, data “business image 1 data” and log exclusion designation “touch panel: (350, 100)-(600, 380)” are indicated, and “business” is image data of the image number “0002”. When displaying “image 1 data”, information representing an operation on a region in a rectangle having the touch panel coordinates (350, 100) and the touch panel coordinates (600, 380) as diagonal vertices in the region of the touch panel unit 111; For example, the pointer for operating the numerical buttons in the area is not displayed. For the image number “0003”, the data “business image 2 data” and the log exclusion designation “touch panel: (350, 100)-(600, 380)” and “touch panel: (100, 520)-(125, 540)” ”And the“ business image 2 data ”that is the image data of the image number“ 0003 ”, the touch panel coordinates (350, 100) and the touch panel coordinates (600, 380) of the area of the touch panel unit 111 are displayed. Information representing operations within a rectangle whose diagonal vertices are in the rectangle, and operations on the rectangular region having the touch panel coordinates (100, 520) and the touch panel coordinates (125, 540) as diagonal vertices, for example, those areas Indicates that the pointer for operating the numeric buttons inside is not displayed.

  FIG. 27 is a diagram showing a log exclusion rule 67 for the example of the log exclusion designation table 66 shown in FIG. The log exclusion rule 67 has a log exclusion rule for each category. The category “ALL” indicates that “no playback is performed for all touch panel operations”, and the category “RECT” is “upper left X coordinate, upper left Y coordinate, lower right X coordinate, and lower right in order of the third to sixth arguments. “Touch panel input in a rectangle with a Y coordinate is not reproduced”, and “NONE” indicates that “all touch panel operations are reproduced”.

  FIG. 28 is a diagram showing an output example 68 of the log exclusion designation table 66 set in accordance with the log exclusion rule 67 shown in FIG. The output example 68 basically indicates log exclusion designation for one screen in one line, and FIG. 28 shows log exclusion designation for three screens. The log exclusion designation for one screen is composed of a plurality of numerical values or character strings separated by commas. The first numerical value indicates the screen number shown in FIG. 26, the second character string indicates the character string indicating the division shown in FIG. 27, and the third and subsequent numerical values or character strings indicate the contents of log exclusion designation. Indicates.

  For example, in the output example “0001, RECT, 350, 100, 600, 380” on the first line, the touch panel coordinates (350, 100) and the touch panel coordinates (600, 380) are paired for the screen with the screen number “0001”. This means that the operation for the area within the rectangle as the corner vertex is not displayed or reproduced. Each number of “350, 100, 600, 380” is an argument of the third to sixth arguments of the category “RECT” of the log exclusion rule 67 shown in FIG. The output example “0002, ALL” on the second line means that all touch panel operations are not reproduced for the screen with the screen number “0002”. The output example “0003, NONE” on the third line means that all touch panel operations are reproduced for the screen with the screen number “0003”.

  FIG. 29 is a diagram showing an example of a second password input screen 75a displayed on the display unit T113 shown in FIG. The personal identification number input screen 75a displays the exclusion area 79 including the operation button display section 76 of the personal identification number input screen 75 shown in FIG. 25 in a color or pattern different from the color or pattern of the area excluding the exclusion area 79. It is. The exclusion area 79 is an area in which the operation for the operation button in the exclusion area 79 is not reproduced even if the operation details of the operation button in the exclusion area 79 are recorded as a log. The operation details of the operation button displayed on the password input screen 75a are, for example, the position touched on the touch panel unit 111 to operate the operation button, specifically, the XY coordinates in the password input screen 75a. It is the information which shows the coordinate position shown. Therefore, for an operation on the operation button in the exclusion area 79, information indicating the operation, for example, a pointer indicated by an image such as a finger is not displayed.

  FIG. 30 is a diagram showing another log exclusion rule 69 different from the log exclusion rule 67 shown in FIG. The log exclusion rule 67 shown in FIG. 27 is a rule for setting a target for excluding log display, that is, reproduction, for each screen. The other log exclusion rule 69 shown in FIG. 30 is a character string displayed on the screen. Or a rule for excluding reproduction of an operation on the touch panel unit 111 by a feature such as a color or a pattern representing the exclusion region 79. Other log exclusion rules 69 may be used separately from the log exclusion rules 67, but may be used in combination with the log exclusion rules 67.

  The other log exclusion rule 69 shown in FIG. 30 has a log exclusion rule for each “category” and includes items of “explanation”, “content”, and “supplement”. “Category” is a category for determining whether to exclude log reproduction or not, and includes a category “STR” and a category “PTN”. “Description” is a description of the category, and the description “character string” indicates that the category “STR” determines whether to exclude log reproduction according to the character string displayed on the screen. "Indicates whether or not the log reproduction is to be excluded according to characteristics such as a color or pattern indicating the exclusion pattern 79 displayed in the drawing pattern, for example, the screen" PTN ". “Content” indicates the specific content of the explanation column, and the content ““ character string ”” indicates a specific character string for determining to exclude log reproduction between ““ ”and“ ””. The content “pattern image file” indicates a file name of a specific drawing pattern for determining to exclude log reproduction. “Supplement” is a supplementary explanation for each category. For category “STR”, an image in which a specific character string such as “password” is embedded is not input / played on the touch panel. For the category “PTN”, “the same image file is embedded and a screen file in which the embedded image file is embedded is not input / played on the touch panel” is indicated.

  FIG. 31 is a diagram showing an output example 90 of the log exclusion designation table 66 set in accordance with the other log exclusion rule 69 shown in FIG. The output example 90 basically shows one log exclusion designation per line, and FIG. 31 shows two log exclusion designations. One log exclusion designation is composed of a plurality of numerical values or character strings separated by commas. The first character string indicates the division shown in FIG. 30, and the second numerical value or character string indicates the content of log exclusion designation.

  For example, in the output example “STR,“ PIN code ”,“ password ”” on the first line, the log exclusion designation category is “STR” and the character string “PIN code” or “password” is displayed. Shows that input reproduction of the touch panel is not performed, that is, display of specifying an operation button operated on the touch panel unit 111 is not performed. Output example “PTN,“ ptn1. jpg "," ptn2. “png” ”indicates that the input / output of the touch panel is not performed when the log exclusion designation category is“ PTN ”and the file name of the pattern drawing file is“ ptn1.jpg ”or“ ptn2.png ”. .

  FIG. 32 is a diagram showing an example of a third password input screen 75b reproduced on the screen display unit 71 shown in FIG. When the log is reproduced, the second password input screen 75a shown in FIG. 29 is reproduced on the screen display unit 71 shown in FIG. 13, and the operation on the operation button in the exclusion area 79 is not displayed. For this reason, it is impossible to know whether or not an operation is performed on the operation button in the exclusion area 79. The code number input screens shown in FIGS. 32 to 34 are screens that allow the user to know that an operation is performed on the operation buttons in the exclusion area 79. On the third password input screen 75b shown in FIG. 32, the character string “password” in the message portion 77 is flashed and an operation for inputting the password is performed on the operation button. The operation buttons to be operated are not shown. For example, the blinking may be performed in synchronization with the timing performed on the operation button.

  FIG. 33 is a diagram showing an example of a fourth password input screen 75c reproduced on the screen display unit 71 shown in FIG. On the fourth password input screen 75c, the character string “password” in the message part 77 is flashed and all the operation buttons are also flashed, and an operation for inputting the password is performed by the operation button. The operation buttons to be operated are not shown. For example, the blinking may be performed in synchronization with the timing performed on the operation button.

  FIG. 34 is a diagram showing an example of a fifth personal identification number input screen 75d reproduced on the screen display unit 71 shown in FIG. On the fifth personal identification number input screen 75d, the range of the exclusion area 79 is displayed blinking to indicate that an operation for inputting the personal identification number is performed on the operation button. Not. For example, the blinking may be performed in synchronization with the timing performed on the operation button.

  FIG. 35 is a flowchart of the input / output log instruction creation processing of the input / output unit 11 shown in FIG. When the input / output unit 11 performs processing related to the log instruction, the process proceeds to step A1. In step A1, a hardware or software interrupt is awaited. In step A2, it is determined whether or not an interrupt has occurred. If there is an interrupt, the process proceeds to step A3. If there is no interrupt, the process returns to step A1. In step A3, an interrupt is processed. In step A4, a log instruction is created based on the processing content that generated the interrupt. In step A5, the log generation unit 121 is notified of the log instruction and the process ends.

  FIG. 36 is a flowchart of the log instruction creation process of the application unit 14 shown in FIG. When the application unit 14 performs display on the screen of the display unit T113, the process proceeds to step B1. In order to perform screen display, the display control unit 16 is notified of the display image number, thereby specifying the screen to be displayed. This designation is performed by an arbitrary application operating on the target machine 10.

  In step B1, image data specified by the image management table 51 shown in FIG. 4 is acquired from the image data unit 141 based on the display image number. In step B2, the image data is adjusted according to the display unit T113. Adjustment means that the image is the whole or a part of the image, and that the image is enlarged, reduced, or superimposed in accordance with the display capability of the display unit T113. In step B3, the adjusted image data is displayed on the display unit T113. In step B4, a log instruction is created based on the display image number. In step B5, the generated log instruction is notified to the log generation unit 121 and the process ends.

  FIG. 37 is a flowchart of the log monitoring process of the log recording control unit 12 shown in FIG. The log recording control unit 12 monitors each unit in the input / output unit 11, and proceeds to Step C1 to generate a log of the operation to be logged.

  In step C 1, the log setting is acquired from the log setting unit 124. In the log setting, all of the operations related to the log, for example, operations related to the input / output unit 11, or errors are set, and the log target operation can be selected by setting the log target in the log setting. In step C2, the operation of the input / output unit 11 is confirmed. That is, the operation of each unit in the input / output unit 11 is monitored. In step C3, it is determined whether or not there is a log target operation. If there is a log target operation, the process proceeds to step C4. If there is no log target operation, the process returns to step C2.

  In step C4, a log is generated for the operation to be logged. In step C5, it is determined whether or not a recording destination log file is specified in the log setting. If specified, the process proceeds to step C7, and if not specified, the process proceeds to step C6. In step C6, the generated log is recorded in the standard log file 151 and the process ends. In step C7, the generated log is recorded in the designated log file 152 and the process ends.

  FIG. 38 is a flowchart of the log recording process of the log recording control unit 12 shown in FIG. When the log instruction from the input / output unit 11 or the display control unit 16 is monitored, the process proceeds to Step D1. In step D1, a log instruction is waited. In step D2, it is determined whether or not there is a log instruction. If there is a log instruction, the process proceeds to step D3, and if there is no log instruction, the process returns to step D1. In step D3, the log setting is acquired from the log setting unit 124. In step D4, it is determined whether or not the log instruction is a log instruction to be logged. If it is a log target, the process proceeds to step D5, and if it is not a log target, the process returns to step D1.

  In step D5, a log is generated for the detected operation to be logged. In step D6, it is determined whether or not a recording destination log file is specified in the log setting. If specified, the process proceeds to step D8, and if not specified, the process proceeds to step D7. In step C7, the generated log is recorded in the standard log file 151 and the process ends. In step C8, the generated log is recorded in the designated log file 152 and the process ends.

  Both the flowcharts shown in FIG. 37 and FIG. 38 are processes by the log recording control unit 12, but operate in separate tasks. However, the start of each flowchart may be connected to the end of another flowchart to continuously operate as one task.

FIG. 39 is a flowchart of the log generation processing of the log generation unit 121 illustrated in FIG.
Called when generating a log in step C4 shown in FIG. 37 or step D5 shown in FIG. 38, the process proceeds to step E1. Therefore, the process is started in a state where the log instruction or the log target operation is specified.

  In step E1, the current date and time is acquired from the system timer unit 13. The date / time does not necessarily have to be the date / time by the system timer unit 13, and any unique date / time that can specify the date / time when the operation to be logged has occurred may be used. The unique date and time is, for example, the elapsed time since the target machine 10 started operating, the date and time according to the clock of the server machine on the same network, or the operating time of the server.

  In step E2, a date / time log character string is created from the acquired date / time. In step E3, the input / output unit log character string corresponding to the input / output unit number is acquired with reference to the input / output unit name definition table 53 shown in FIG. In step E4, the action log character string corresponding to the action number is acquired with reference to the action name definition table 54 shown in FIG. In step E5, with reference to the operation detail creation rule table 55 shown in FIG. 8, the operation detail log string creation rule corresponding to the combination of the input / output unit number and the operation number, that is, the operation detail log creation rule is acquired. To do.

  In step E6, an operation detail log character string is created based on the acquired operation detail log creation rule. In step E7, the date / time log character string created in step E2, the input / output unit log character string obtained in step E3, the operation log character string obtained in step E4, and the operation detail log character string created in step E6 are combined. Generate a log and exit. The operation information generation process is, for example, step E1 to step E7 of the log generation process shown in FIG.

  FIG. 40 is a flowchart illustrating an example of log reproduction processing of the log reproduction control unit 28 illustrated in FIG. For example, when the log reproduction function is selected by the operation unit 26, the process proceeds to step F1.

  In step F1, a log file name selection screen for selecting a log file name to be reproduced is displayed on the display unit S25. In step F2, the operation unit 26 waits for a log file name to be selected. If the log file to be played back is specified before the function to play back the log is selected, for example, before moving to Step F1, Step F1 and Step F2 may be skipped.

  In step F3, it is determined whether a plurality of log files have been selected. When a plurality of log files are selected, the process proceeds to step F11. When one log file is selected, the process proceeds to step F4. In step F4, the selected log file is read into the buffer unit 22. In step F5, the date and time when the log recording was started and the date and time when the log recording was completed, that is, the date and time of the last recording were acquired from the buffer unit 22. Since the logs in the buffer unit 22 are sorted in order of date and time, the date and time of the first row and the date and time of the last row are acquired.

  In step F6, the log reproduction setting file is read. That is, the log exclusion designation table 66 is read from the log reproduction setting file unit 82. In step F7, the log non-replay flag “r_flg” is initialized, that is, “0” is substituted.

  In step F8, a reproduction condition input screen for inputting reproduction conditions is displayed. The reproduction condition is, for example, a condition that a log having an input date and time from the start to the end of the log is reproduced, or a condition that a log that matches or includes the inputted character string is reproduced. In step F9, it is determined whether or not a reproduction condition is designated. If the reproduction condition is designated, the process proceeds to step F10, and if the reproduction condition is not designated, the process proceeds to step F12. In step F10, a log that matches the specified reproduction condition is searched from the logs in the buffer unit 22, and when the first log in the buffer unit 22 is the first line, the value of the line number of the searched log is “ The value obtained by subtracting “1” is substituted into the counter “n”, and the process proceeds to Step F20 in FIG. 41 or Step F40 in FIG.

  In step F11, all the selected log files are read into the buffer unit 22, the logs are sorted using the date and time of each log line as a key, and the process proceeds to step F5. In Step F12, “0” is substituted into the counter “n”, and the process proceeds to Step F20 in FIG. 41 or Step F40 in FIG.

  FIG. 41 is a flowchart showing an example of log reproduction processing of the log reproduction control unit 28 shown in FIG. In step F20, “1” is added to the counter “n”, and the pointer is advanced to the next line. In step F21, the log of the “n” line is read from the buffer unit 22 for one line. In step F22, the log analysis unit 23 analyzes the read log. The analysis reveals what the log was doing. In Step F23, it is determined whether or not another line log is necessary for reproduction. Since one operation may be divided and recorded in a log having two or more lines, it is determined whether or not another line is necessary. There are cases where playback is not possible if there are not enough logs. If another line log is necessary, the process returns to step F20, and if another line log is not necessary, the process proceeds to step F24.

  In step F24, it is determined whether or not the log is a screen display, that is, whether or not the operation indicated by the log is related to the screen display. If the log is a screen display log, the process proceeds to step F25. If the log is not a screen display log, the process proceeds to step F28. In step F25, since the information about the screen image is included in the log, the information including the screen number and the screen image is acquired from the screen image file DB 24.

  In step F26, the corresponding screen No. Determines whether or not to exclude touch panel input reproduction. That is, if the screen number of the screen image acquired from the screen image file DB 24 is not the screen number for which log exclusion designation is set in the log exclusion designation table 66, the corresponding screen No. Determines that it is not a touch panel input reproduction exclusion designation, and proceeds to step F27. If the screen number of the screen image acquired from the screen image file DB 24 is a screen number for which log exclusion designation is set in the log exclusion designation table, the corresponding screen No. Determines that it is a touch panel input reproduction exclusion designation, and proceeds to step F33. In Step F27, “0” is substituted for the log non-replay flag “r_flg”. In Step F28, it is determined whether or not the log non-replay flag “r_flg” is “1”. If the log non-replay flag “r_flg” is “1”, the process proceeds to step F34, and if the log non-replay flag “r_flg” is not “1”, the process proceeds to step F29.

  In step F29, a reproduction screen image to be displayed is generated from the acquired screen image and the operation indicated by the log. If reproduction of the display indicating the operated operation button indicated by the touch panel log is excluded in step F35, a reproduction screen excluding the display indicating the operated operation button is generated. In Step F30, the generated reproduction screen image is displayed on the display unit S25. In step F31, it is determined whether all the logs in the buffer unit 22 have been read. If all the logs have not been read, the process proceeds to step F32. If all the logs have been read, the process ends. The log file selection screen can also be displayed by returning to the start at the end. In step F32, the process waits for wait w seconds and returns to step F20.

  In Step F33, “1” is substituted for the log non-replay flag “r_flg”, and the process proceeds to Step F28. In step F34, it is determined whether the log is a touch panel log. If it is a touch panel log, the process proceeds to step F35, and if it is not a touch panel log, the process proceeds to step F29. In step F35, it is determined whether or not the input position is within the target range. When the log exclusion designation without the area designation is set in the log exclusion designation table 66, or the log exclusion designation with the area designation is set in the log exclusion designation table 66, and the coordinate position of the operated operation button is If it is within the area set in the log exclusion designation table 66, it is determined that the input position is within the target range, and the process proceeds to Step F36. If the log exclusion designation is not set in the log exclusion designation table 66, it is determined that the input position is not within the target range, and the process proceeds to Step F29. In step F36, the touch panel log is excluded from the reproduction target, and the process proceeds to step F29. That is, the reproduction of the display indicating the operated operation button indicated by the touch panel log is excluded, and the process proceeds to Step F29.

  FIG. 42 is a flowchart showing another example of the log reproduction processing of the log reproduction control unit 28 shown in FIG. In Step F40, “1” is added to the counter “n”, and the pointer is advanced to the next line. In step F41, the log of the “n” line is read from the buffer unit 22 for one line. In step F42, the log analysis unit 23 analyzes the read log. The analysis reveals what the log was doing. In Step F43, it is determined whether or not another line log is necessary for reproduction. Since one operation may be divided and recorded in a log having two or more lines, it is determined whether or not another line is necessary. There are cases where playback is not possible if there are not enough logs. If another line log is required, the process returns to step F40, and if another line log is not required, the process proceeds to step F44.

  In step F44, it is determined whether or not the log is a screen display log, that is, whether or not the operation indicated by the log is related to the screen display. If the log is a screen display log, the process proceeds to step F45. If the log is not a screen display log, the process proceeds to step F46. In step F45, since the information about the screen image is included in the log, the information including the screen number and the screen image is acquired from the screen image file DB 24.

  In step F46, it is determined whether or not the display unit has been changed. If there is a change in the screen displayed on the display unit S25, it is determined that the display unit has been changed, and the process proceeds to step F47. If there is no change in the screen displayed in the display unit S25, the display unit is changed. It determines with there not being, and progresses to step F50. In step F47, the screen content displayed on the display unit is confirmed. That is, it is confirmed whether there is a character string or a drawing pattern shown in the log exclusion designation table 66 set according to the other log exclusion rule 69 shown in FIG. 30 on the screen displayed on the display unit S25. In step F48, it is determined whether or not there is an area drawn with a specific color, pattern, or character string on the display screen. If there is an area drawn with a specific color, pattern, or character string on the display screen, the process proceeds to step F49. If there is no area drawn with a specific color, pattern, or character string on the display screen, the process proceeds to step F50. In step F49, the area drawn with a specific color or pattern on the display unit is used as a touch panel log exclusion instruction, and touch panel input reproduction is not performed.

  In step F50, a reproduction screen image to be displayed is generated from the acquired screen image and the operation indicated by the log. When it is determined in step F49 that touch panel input reproduction is not performed, a reproduction screen excluding the display indicating the operation button operated on the touch panel unit 111 is generated. In step F51, the generated reproduction screen image is displayed on the display unit S25. In step F52, it is determined whether all the logs in the buffer unit 22 have been read. If all the logs have not been read, the process proceeds to step F53, and if all the logs have been read, the process ends. The log file selection screen can also be displayed by returning to the start at the end. In step F53, the process waits for wait w seconds and returns to step F40.

  The display process includes, for example, steps F1 to F12 of the log reproduction process shown in FIG. 40 and steps F20 to F36 of the log reproduction process shown in FIG. 41, or steps F1 to F12 of the log reproduction process shown in FIG. These are Step F40 to Step F53 of the log reproduction process shown in FIG.

  The processing shown in FIGS. 40 to 42 can be ended at an arbitrary scene by the operation of the operation unit 26, and can be temporarily stopped and re-executed from the temporary stop. In addition, along with the log file selection, you can specify the logs in the log file by file size, number of lines, or date and time recorded in the log, and read logs from the log file to any log in the log file. It is also possible to start with.

  As for the playback speed, it is possible to insert an arbitrary time or a fixed time specified by the operation unit 26 between each step shown in FIGS. 40 to 42, during the loop, or before and after the jump, for example, a weight w seconds. As a result, the playback speed can be adjusted. By setting the time w used for the weight based on the date and time recorded in the log, it is possible to reproduce the log in real time. The value of w can be arbitrarily changed by the operation unit 26 when starting the processing of the flowchart or during the loop processing from Step F9 to Step F18.

  In the log reproduction process shown in FIGS. 40 to 42, the log recorded in the log file is reproduced. However, when reproducing the log in real time, the log receiving unit S29 receives the log from the target device 10 and logs the log. Each time it is received, it is determined whether or not there is a log exclusion designation, and if there is a log exclusion designation, the display showing the operated operation button may not be reproduced.

  As described above, the touch panel unit 111 that is an operation unit has operation buttons that are a plurality of operation units for inputting information, and the operation unit of the operation unit is changed by the log generation unit 121 that is an operation information generation unit. When operated, a log as operation information for specifying the operated operation unit is generated, operation information is displayed by the display unit S25 as a display unit, and operation is performed by a log reproduction control unit 28 as a storage unit. Display exclusion conditions that pre-determine information non-display conditions are stored.

  Then, it is determined by the log reproduction control unit 28 that is a determination unit whether or not the operation information generated by the operation information generation unit satisfies the display exclusion condition stored in the storage unit, and the log reproduction that is the control unit When the control unit 28 determines that the generated operation information satisfies the predetermined display exclusion condition by the determination unit, the operation information satisfying the stored display exclusion condition is not displayed on the display unit. Therefore, it is possible to prevent information that needs to be kept secret, such as personal information, from being disclosed to a third party together with information representing an operation performed on the apparatus. In other words, leakage of personal information to a third party can be prevented.

  Further, the touch panel unit 111 as an operation unit has operation buttons as a plurality of operation units for inputting information, and the operation unit of the operation unit is operated by the log generation unit 121 as an operation information generation unit. Then, a log that is operation information for specifying the operated operation unit is generated, the operation information is displayed by the display unit S25 that is a display unit, and the operation information is not displayed by the log reproduction control unit 28 that is a storage unit. Display exclusion conditions for which display conditions are set in advance are stored.

  Then, it is determined by the log reproduction control unit 28 that is a determination unit whether or not the operation information generated by the operation information generation unit satisfies the display exclusion condition stored in the storage unit, and the log reproduction that is the control unit When the control unit 28 determines that the generated operation information satisfies the predetermined display exclusion condition by the determination unit, the operation information is replaced with another expression and displayed on the display unit. Information that needs to be kept secret, such as personal information, can be prevented from being disclosed to a third party together with information representing an operation performed on the apparatus. In other words, leakage of personal information to a third party can be prevented.

  Furthermore, since the predetermined display exclusion condition is operation information related to an operation in a state where the character string information representing the predetermined character string is displayed by the display means, personal information such as a personal identification number or a password is input. It is possible to keep the numeric button operated when the character requesting is displayed. Therefore, it is possible to prevent leakage of personal information to a third party in response to an input request such as a password or a password.

  Furthermore, since the predetermined display exclusion condition is operation information related to an operation in a state where information having a predetermined characteristic is displayed by the display means, it is possible to keep a numerical button operated on a specific screen secret. it can. Therefore, it is possible to prevent leakage of personal information to a third party in response to a specific screen.

  Furthermore, in the log generation process shown in FIG. 39, which is an operation information generation process, when any one of the operation buttons as operation buttons for inputting information is operated, operation information related to the operation is displayed. In the log reproduction process shown in FIGS. 40 to 42, which is a display process, a certain log is generated, and operation information excluding operation information that satisfies a predetermined display exclusion condition among the operation information generated in the operation information generation process. Therefore, it is possible to prevent information that needs to be kept secret, such as personal information, from being disclosed to a third party together with information representing an operation performed on the apparatus. In other words, if the information display method according to the present invention is used, leakage of personal information to a third party can be prevented.
