Description

  The present invention relates to an information processing apparatus and information processing method using application software, and a computer program, and in particular, an information processing apparatus and information processing method for improving the efficiency of a user's input operation using application software, and It relates to computer programs.

  More specifically, the present invention relates to an information processing apparatus and an information processing apparatus that efficiently execute a user's input operation by repeatedly using a history of operations performed by a user in the past when using application software. The present invention relates to a method and a computer program, and in particular, an information processing apparatus and an information processing method for reproducing an operation previously performed by a user or repeatedly executing a series of operations performed from a certain point in the past, and a computer program Regarding the program.

  With rapid progress in the field of information technology (IT), various forms of computer systems have been developed and manufactured, and are widely used in universities and other research institutions, corporate offices, and even ordinary homes. On the computer, the application applied to each business is started, and various media such as voice, image, natural language, etc. are digitized and handled mathematically to edit, process, store, manage, transmit and share information. It is possible to perform more advanced and diverse processes.

  Recently, as a computer application, the behavior of a physical, ecological, or social system is expressed or modeled, and the behavior of a system governed by almost the same law is simulated on a computer, that is, Simulation is widely used. By using simulation technology, the system behavior in various aspects can be predicted before actual experience, and the system can be controlled based on the obtained parameters to predict and prevent system errors. An error can be avoided by performing control.

  Here, when using application software, there is a case where it is desired to reproduce an operation performed by the user in the past or to repeatedly execute a series of operations performed from a certain point in the past. For example, in the above simulation calculation, the parameters input by the operator are input to the simulation engine and the behavior analysis calculation is executed. However, it is necessary to repeat the simulation calculation using the same model formula while changing the parameters. . In such a case, the operator has to repeat a series of input operations, which is troublesome. For this reason, there is a desire to repeatedly execute a specific range of operation histories performed in the past, or to re-create a partially changed operation such as parameter resetting during repeated execution.

  For example, in editing applications such as word processors and spreadsheets, it is common to equip functions such as “Undo” and “Redo”. Therefore, the convenience of editing work is achieved.

  However, the functions such as “undo” and “redo” are not only movements up to the desired operation point, but also a function of editing the operation history to repeat a series of operations or to reproduce by partially changing. Is not prepared.

  For example, as shown in FIG. 13, it is assumed that an input operation has been performed in the past in time sequence order of OP # 6, OP # 5, OP # 4, OP # 3, OP # 2, OP # 1, and OP # 0. . In this case, when going back to OP # 3 by the “undo” function, it disappears from the operation history of the subsequent input operations OP # 2 to OP # 0 and cannot be used repeatedly. In other words, the past operation history cannot be repeated within a specific range.

  For example, suppose that it is desired to repeatedly execute parameters in some input operations while resetting parameters in the range of OP # 3 to OP # 0. If you go back to the operation item OP # 3 with the "Undo" function and change the input operation here, the subsequent input operations OP # 2 to OP # 0 will disappear from the operation history. Must. Thereafter, when repeating the operation contents in the operation item OP # 3 in the range of OP # 3 to OP # 0, it is necessary to re-input the input operations OP # 2 to OP # 0.

  In short, the functions such as “Undo” and “Redo” are, for example, a simulation software that repeats data input and result analysis. It cannot be used.

  Further, for example, when it is desired to reproduce an operation of analyzing or analyzing a graph drawn as a simulation result while changing the viewpoint using the mouse, it is necessary to record even the coordinates where the mouse has moved. Saving all the coordinate data of the mouse movement trajectory operated by the user by a method such as the operation log described above makes later editing work difficult and leaves a lot of useless history. In terms of securing the memory area, it is not efficient.

  For example, there has been proposed a synchronous playback method that enables the same result to be obtained during playback when the movement of the mouse performed by the operator is played back later on another terminal (see, for example, Patent Document 1). ) However, in this method, the input event and result event on the operation extraction terminal are stored in the order in which the operation and processing are performed, and the input event and result event are sequentially played back on the operation playback terminal side according to the stored order. The operation content is not changed at the time of reproduction. That is, storing / reproducing the operation history by this synchronous reproduction method is equivalent to reproducing (playing) data recorded on the CD, and no change in the operation history is allowed.

  Note that, as means for editing the operation history and customizing the repeated operation, a macro recording function and a function for programming only an operation required by the user from the operation log can be considered. However, in macro recording, it is not possible to record only the necessary parts retroactively. In addition, in order to use operation logs, it is necessary for the user to learn the application-specific (macro) language, and then to extract and edit only the necessary parts, which takes time and other difficulties. is there.

For example, general functions such as “Undo” and “Redo” can be used to move the user's input in the past in the time series. The operation history editing function is not provided.

  On the other hand, the information processing apparatus according to the present invention efficiently records an operation history necessary for a user when executing an application in response to a user's input operation on a computer system, and implements it in the past according to the purpose. The operation is easily reproduced from the GUI, and the operation history is partially changed if necessary.

  The operation history editing means presents the operation history recorded in the time series order to the user, traces back the user operation to a location or range designated by the user on the time series, or rearranges the operation time series. Edit the operation history. The application reproduction unit reproduces the execution of the application according to the operation history edited by the operation history editing unit. When specifying the location or range of the operation history on the time series, the user may select either the time or the number of steps, for example.

  Here, the operation history recording means classifies the operations that can be performed by the user from the application for each function and records the operation history, and the application reproduction means reproduces the operation history according to the classification. May be.

  Specifically, the operation history recording means records the operation history by classifying the operation history into one that does not permit the user to change contents during reproduction. The application reproduction means reproduces the execution of the application after changing the contents as required by the user when reproducing the operation history whose contents are permitted to be changed. Therefore, after executing a series of operations, the user must go back to the required operation step, edit the necessary parts, etc., and rewrite or save the operations for reuse. Can do.

  Further, the operation history recording means may record each operation history with a storage priority. In such a case, the operation history efficiency is improved by deleting or compressing the recorded operation histories in order from the one with the lowest storage priority, and leaving more operation histories with higher priority in the record. Can be reused. In such a case, there is an effect of eliminating waste of the storage area in addition to efficiently using the operation history. Furthermore, it is possible to delete from the history with low priority at any time, and it is not necessary to secure a huge storage area.

  A second aspect of the present invention is a computer program written in a computer-readable format so as to execute processing according to a user's input operation on the computer system. A user input procedure for accepting an operation by a user, an application execution procedure for executing an application in accordance with the user operation input by the user input procedure, and a history of user operations input by the user input procedure are recorded in time series order An operation history recording procedure, an operation history editing procedure for editing a user's operation history recorded in chronological order by the operation history recording procedure, and execution of an application according to the user operation edited by the operation history editing procedure. Special application execution procedure. It is a computer program that.

  The computer program according to the second aspect of the present invention defines a computer program described in a computer-readable format so as to realize predetermined processing on a computer system. In other words, by installing the computer program according to the second aspect of the present invention in the computer system, a cooperative action is exhibited on the computer system, and the information processing according to the first aspect of the present invention is performed. The same effect as the apparatus can be obtained.

  According to the present invention, when using application software, it is possible to execute processing by repeatedly using an operation history executed by the user in the past, and to improve the efficiency of user input operations. An apparatus, an information processing method, and a computer program can be provided.

  According to the present invention, when an application is executed on a computer system in accordance with a user input operation, an operation history necessary for the user is efficiently recorded, and operations performed in the past according to the purpose can be easily performed from the GUI. The operation history can be partially changed if necessary.

  In other words, when the application software is running on a computer system such as a personal computer, the user goes back to the necessary operation steps after executing a series of operations, and rewrites only necessary parts. After editing, you can reproduce the operation or save it for reuse.

  Further, according to the present invention, the operations performed by the user are classified into operations that can be rewritten or edited at the time of reuse and operations that are not, and the contents that are automatically stored are differentiated, or the priority of storage is further increased. In addition, the operation history can be efficiently reused.

  In contrast to the method of saving all operation histories from the start to the end of the operation, making a difference in the contents automatically stored by the function eliminates the waste of storage space in addition to efficient use of the operation history. There is an effect. Furthermore, it is possible to delete from the history with low priority at any time, and it is not necessary to secure a huge storage area.

  In addition, according to the present invention, when the user wants to reproduce the operation that the user casually performed while executing the application again, or when the user wants to change and repeat a series of operations, the user can remember the operation, There is no need to repeat the same operation over and over. Further, the user can easily store and reproduce the operation history by specifying the number of operation steps and the time to be traced without learning a complicated programming language unique to the application.

  Other objects, features, and advantages of the present invention will become apparent from more detailed description based on embodiments of the present invention described later and the accompanying drawings.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 schematically shows a hardware configuration of an information processing apparatus according to an embodiment of the present invention. On the information processing apparatus, an application is executed in accordance with a user input operation. The application referred to here is, for example, an application such as analysis / analysis / simulation, CAD, or the like that trials and errors the relationship between the input and the result. The information processing apparatus can be configured by a general computer system such as a personal computer (PC). Hereinafter, each part will be described.

  This information processing apparatus is configured around a processor 10. The processor 10 executes various processes based on a program stored in a memory under a program execution environment provided by an operating system (OS). The processor 10 controls various peripheral devices connected via the bus 30. The peripheral devices connected to the bus 30 are as follows.

  The memory 20 is composed of a semiconductor memory such as a DRAM (Dynamic RAM), for example, and is used for loading a program code executed in the processor 10 and temporarily storing work data of the execution program. The memory 20 constitutes a memory space of the processor 10.

  The display controller 21 generates a display image according to the drawing command sent from the processor 10 and sends it to the display device 22. The display device 22 connected to the display controller displays the image on the screen according to the display image information sent from the display controller 21.

  The input / output interface 23 is connected to a keyboard 24 and a mouse 25, and transfers input signals from the keyboard 24 and mouse 25 to the processor 10.

  The network interface 26 is connected to an external network such as a LAN or the Internet, and controls data communication via the Internet. That is, the data sent from the processor 10 is transferred to another device on the Internet, and the data sent via the Internet is received and passed to the processor 10. For example, programs and data can be received from outside via a network.

  A hard disk drive (HDD: Hard Disk Drive) controller 27 is connected to a large-capacity external storage device 28 such as an HDD, and controls input / output of data to / from the HDD 28 to which the HDD controller 27 is connected. The HDD 28 stores an operating system (OS) program to be executed by the processor, an application program, a driver program, and data and contents to be referred to or reproduced by the program. In the present embodiment, each program is installed on the HDD 28 in an executable format.

  In addition, in order to configure the information processing apparatus, many electric circuits other than those shown in FIG. 1 are required. However, since these are well known to those skilled in the art and do not constitute the gist of the present invention, they are omitted in the present specification. Also, it should be noted that only a part of the connections between the hardware blocks in the figure is shown in order to avoid the confusion of the drawings.

  On the information processing apparatus shown in FIG. 1, for example, an application such as analysis / analysis / simulation, CAD, etc. that trial and error the relationship between the input and the result, and various other forms of applications are executed. can do.

  Here, when using application software on a computer system, there is a case where it is desired to reproduce an operation performed in the past by a user or to repeatedly execute a series of operations performed from a certain point in the past.

  Conventional functions such as “Undo” and “Redo” can be used to move the operation entered by the user in the past in the time series by using the past operation history. It does not have an operation history editing function that can be partially changed and reproduced.

  On the other hand, on the information processing apparatus according to the present invention, when an application is executed on a computer system according to a user's input operation, an operation history necessary for the user is efficiently recorded, and in the past according to the purpose. The performed operation can be easily reproduced from the GUI, and the operation history can be partially changed if necessary.

  FIG. 2 schematically shows a functional configuration of an application execution environment included in the information processing apparatus according to the present invention. The illustrated application execution environment includes a user input unit 51, an application execution unit 52, an operation history recording unit 53, an operation history editing unit 54, and an application reproduction unit 55.

  The user input unit 51 receives user operations on user input devices such as the keyboard 24 and the mouse 25.

  The application execution unit 52 executes an application such as a simulator or CAD by applying a user instruction operation received by the user input unit 51 or input parameters.

  The operation history recording unit 53 records the user operation history via the user input unit 51 in the order of time series. The operation history recording unit 53 may record the operation history by classifying the operations that the user can perform from the application for each function. Specifically, the operation history is recorded by classifying the content change by the user at the time of reproduction and the content not permitted by the user. For example, the recorded contents are different depending on the purpose of reproduction, such as storing only executed operations or storing all the trajectory coordinates of the movement of the mouse. In such a case, when reproducing the operation history in which the content change is permitted, it is possible to reproduce the execution of the application after changing the content as required by the user.

  Further, the operation history recording unit 53 may record each operation history with a storage priority. Then, the recorded operation histories are deleted or compressed in order from the lower storage priority, and the operation histories with higher priority are left in the record more efficiently. Can be used. In such a case, there is an effect of eliminating waste of the storage area in addition to efficiently using the operation history. Furthermore, it is possible to delete from the history with low priority at any time, and it is not necessary to secure a huge storage area.

  The operation history editing unit 54 edits the user operation history recorded by the operation history recording unit 53 in order of time series. Specifically, the operation history recorded in time series order is presented to the user on the GUI screen. Then, the user operation is traced back to the location or range designated by the user on the operation history screen arranged in time series order, and this is passed to the application reproduction unit 55 to repeatedly execute processing based on the same operation. When specifying the location or range of the operation history on the time series, the user may select either the time or the number of steps, for example. Alternatively, the time series order of operations performed by the user in the past may be rearranged and passed to the application reproduction unit 55.

  The application reproducing unit 55 reproduces the execution of the application by applying the user operation edited by the operation history editing unit 54. When the operation history recording unit 53 records the operation history by classifying the content change by the user as permitted or not permitted during reproduction, the application reproduction unit 55 performs the operation whose content change is permitted. When reproducing the history, change the contents as required by the user and then reproduce the execution of the application.

  FIG. 3 schematically shows a mechanism for reproducing an application by repeatedly using a history of operations performed by the user in the past in the application execution environment shown in FIG. Application reproduction is roughly divided into four stages: acquisition of a user's operation history, storage and storage of the acquired operation history, editing of the operation history, and reproduction of the application by reuse of the operation history.

  The user's operation history performed through the user input device such as the keyboard 24 and the mouse 25 is acquired by the user input unit 51 and is recorded by the operation history recording unit 53 in the time series order.

  When the operation history is acquired by the user input unit 51, the operations that can be performed from the application are classified for each function. Then, the operation history recording unit 53 records the operation history by classifying the content change by the user into those that are not permitted during reproduction and those that are not permitted. For example, the recorded contents differ depending on the purpose of reproduction, such as storing only the executed operation / all the trajectory coordinates moved by the mouse.

  The operation history recording unit 53 records each operation history with a storage priority. As time elapses, the data size of the accumulated operation history gradually increases. Therefore, the recorded operation histories are deleted or compressed in order from the lowest storage priority, and the operation history with higher priority is left in the record. As a result, the operation history is efficiently reused and the storage area is secured.

  In the operation history editing stage, the operation history recorded in time series order is presented to the user on the GUI screen. On this screen, the user can specify the location of the operation history to be executed retroactively and the range to be repeatedly executed. Alternatively, it is possible to specify replacement of the operation history in time sequence order. When specifying the location or range of the operation history on the time series, the user may select either the time or the number of steps, for example.

  At the stage of reproducing the application, the edited operation history is applied and the execution of the application is repeated. At this time, when the operation history recording unit 53 records the operation history by classifying the content change by the user as permitted or not permitted during reproduction, the application reproduction unit 55 is permitted to change the content. When reproducing the current operation history, the application is reproduced after changing the contents as required by the user.

  FIG. 4 schematically shows a state in which an application is reproduced by repeatedly using past user operation histories. In the example shown in the figure, it is assumed that an input operation has been performed in the past in the time series order of OP # 6, OP # 5, OP # 4, OP # 3, OP # 2, OP # 1, and OP # 0. Yes.

  On the GUI screen, as shown in FIG. 4, entries corresponding to the respective operation histories are arranged in the past in a time series order. The user can specify the location and range of the operation history to be reproduced retroactively on such a GUI screen. Alternatively, the order of the operation history can be changed by applying a drag operation to the entry.

  Here, it is assumed that the user goes back to # OP3 and wants to repeatedly use the operation history in the range of # OP3 to # OP0. Of these, # OP1 and # OP0 are classified as allowing the user to change the contents at the time of reproduction. In this case, the application reproduction unit 55 repeatedly executes the operation history in the range of # OP3 to # OP0, but when executing # OP1 and # OP0, the user is prompted to change contents such as re-input of parameters. . Then, the contents newly specified by the user are applied to reproduce the application.

  As a result, the operation history is updated as shown in FIG. Further, when the operation history is repeatedly executed in the range of # OP3 to # OP0 and the contents are changed when executing # OP1 and # OP0, the operation history is updated as shown in FIG.

  In the example shown in FIGS. 4 to 6, when specifying the location and range of the operation history on the time series, the user selects by the number of steps. Of course, the operation history can be made by time. It can also be implemented.

  Hereinafter, a specific embodiment of the present invention will be described by taking an application for executing a calculation simulation as an example.

  FIG. 7 shows an example of a screen configuration for displaying and outputting a simulation result in an application for executing a calculation simulation.

  The illustrated screen uses a menu bar having a plurality of menu items, a data input area on the left side of the screen having input fields for inputting parameters A to D necessary for simulation, and input parameters. A result display area on the right side of the screen for displaying the results of the simulation performed.

  Menu items such as file, display, analysis, and history playback are arranged in the menu bar. Each menu item has pull-down menus such as save / playback, 2D-3D switching on / off, calculation start / mode setting, step number designation / time designation.

  Also, in the data input area, numerical values for each parameter can be substituted or rewritten.

Further, in the result display area, to follow the trajectory 3D object to be simulated is drawn by the displayed mouse, rotation and perspective transformation of an object, such as the scale of color change is made.

  Then, the application software substitutes the parameters, responds to the selection of the “calculation start” command, executes the calculation inside the calculation function of the information processing apparatus, and draws the result in the result display area on the right. can do.

  In this application, the operations performed by the user are classified into three: (1) pull-down menu, (2) data substitution unit, and (3) result display window. The operations performed by the user in each classification and the contents automatically stored in the history are as follows.

  In (1), the user selects a software control command such as file saving or calculation execution. The system stores the executed commands as a history in chronological order.

  In (2), the user inputs numerical values and character data from a keyboard or the like. In the information processing apparatus, operations such as substitution / rewriting of each parameter and input numerical values are stored as a history in order of time series.

  In (3), the user changes the viewpoint of the calculation result drawn using the mouse, switches the display method, and colors the calculation result. In the information processing apparatus, mouse movement coordinates, a selected color, display switching operation, and the like are stored as a history in order of time series.

  Here, when the user selects the history reproduction menu from the menu bar of the GUI screen shown in FIG. 7, a dialog for confirming whether to specify the operation history by time or the number of steps (see FIG. 8). ) Appears. Here, when the user selects the number of steps, the screen is switched to a dialog for designating the number of steps (see FIG. 9).

  It is assumed that the user has selected the past four steps as reproduction targets on this dialog. It is assumed that the past four steps are operations shown in Table 1 and a history is stored.

  When the operation history is recorded, the operations that the user can perform from the application are classified for each function. Specifically, the operation history is recorded by classifying the content change by the user at the time of reproduction and the content not permitted by the user. In the example shown in Table 1, the substituted data can be changed by the data substitution command, but the operation for executing parameter substitution and the mouse coordinate instruction operation cannot be changed. If the mouse coordinate instruction operation can be changed, the number of designated coordinate points is generally large, and the parameter rewriting operation during reproduction becomes complicated.

  In the operation history for the past four steps, the assigned data can be changed by the parameter A input and the parameter B input, respectively. Accordingly, in response to designation of the past four steps in the dialog shown in FIG. 9, a window for inputting parameters A and B as shown in FIG. 10 is displayed to the user. The user can reproduce the application after changing this parameter if necessary.

  In the example shown in Table 1, the priority of the coordinate storage of the mouse is low, and the priority of recording the parameter value input and command execution is high. The user can repeatedly perform calculation / analysis while changing the parameter, for example, A → A ′ → A ″ using the playback function. The operation history with higher priority is recorded in the record. This makes it possible to efficiently reuse the operation history, and to reduce the priority of the operation history that increases the storage capacity, such as the storage of the designated coordinates of the mouse, thereby eliminating the waste of the storage area. effective.

  According to the present invention, the fact that the stored operation history contents can be partially changed at the time of reproduction is particularly effective for an application such as analysis, analysis, simulation, CAD, etc. in which the relationship between the input and the result is trial and error. is there.

  FIG. 11 shows an operation of editing an operation history and reproducing an application according to the present invention. FIG. 12 illustrates a conventional “Undo” operation. As described above, according to the present invention, the time required for the numerical input A, the numerical input B, and the graph creation while rewriting the input parameter values as A, A ′, A ″, etc., is traced back to the operation history of numerical input. Since the operation history in the sequence order can be used repeatedly, the operability is remarkably improved when the simulation calculation using the same model formula is repeated while changing the parameters.

  On the other hand, in the “Undo” operation, when there is an operation history in the order of time series of numerical input A, numerical input B, and graph creation, the reverse graph creation, numerical input B, numerical input A However, for example, the input parameter value A cannot be rewritten by the numerical input A. Further, when a new numerical input A ′ operation is performed retroactively to the operation of numerical input A, a new operation history is created at that time, and the subsequent operation history of numerical input B and graph creation is lost. You must input the operation again. This is troublesome compared with the operation according to the present invention described above.

  The present invention has been described in detail above with reference to specific embodiments. However, it is obvious that those skilled in the art can make modifications and substitutions of the embodiment without departing from the gist of the present invention.

  According to the present invention, it is possible to store user operation history contents performed at the time of executing an application, and to partially change and use the contents at the time of reproduction. However, such a function can be used for applications such as analysis, analysis, and simulation. In addition, the present invention works particularly effectively for applications such as CAD, which are executed in response to user input operations, particularly for applications where the relationship between input and results is trial and error.

  In short, the present invention has been disclosed in the form of exemplification, and the description of the present specification should not be interpreted in a limited manner. In order to determine the gist of the present invention, the claims should be taken into consideration.
