Description

  The present invention relates to a program, an input form control method, and a data processing apparatus.

  In application software and Internet browsers, input forms for inputting data are frequently used. The user inputs a character string and a numerical value for each item of the input form using various input interfaces (keyboard, mouse, touch panel, etc.). When the input is completed, the user presses a button for registration or storage, and transmits the input content to the server.

  When there are many items included in the input form or items that require complex items are included, the input load of the user is large and input takes time. In such a case, there is a high possibility that the application software or the browser is terminated due to an erroneous operation or the like while inputting to the input form. For example, the user may accidentally press the browser end button (x button) or end the session by pressing the terminal home button.

  Patent Document 1 discloses a data processing apparatus that does not require input from the beginning even when data input on the input form is interrupted without being performed to the end. The data processing apparatus temporarily stores the input contents of the input form in the server triggered by pressing of the save button (Patent Document 1, FIG. 1, 0028, etc.).

Japanese Patent Application Laid-Open No. 2004-110636

  In the configuration of Patent Document 1, it is suggested that when a plurality of users edit the same input form, data input to the input form by the server is temporarily stored (paragraph 0060). However, there is no suggestion or teaching about the access right to the data stored by the server. Therefore, in the configuration of Patent Document 1, there is a possibility that another user can use the contents of the input data of the input form temporarily saved by one user. As a result, there is a risk of theft of the contents of the input data. For example, when the input form includes items requesting physical information (height, weight, medical history, etc.), it is not preferable that the contents input by other users can be referred to.

  The present invention has been made in view of the above problems, and a program and an input that can reduce the burden of re-input of the input form while avoiding a security risk even when the input form ends in the middle of input It is a main object to provide a form control method and a data processing apparatus.

  One aspect of the program according to the present invention includes an acquisition step of writing, in a storage unit, cache information that associates input data to an input form with user information being operated in a storage unit, and redisplaying the input form. Cache control for setting the input data written in the storage unit as a default value in the input form only when the user who made the re-display request corresponds to the user information written in the storage unit Step.

  The acquisition unit associates user information and input data to the input form and writes them in the storage unit while an input form is input by a certain user. The form control unit provides an input form in which data that was being input is set as a default value only when the user who has made the previous input is the same as the user who has made the redisplay request. Thereby, the medical staff can continue the input in a state where the data being input is restored even when the unintended application ends. That is, it is possible to greatly reduce the labor of input by the medical staff. In addition, since the data is restored only when the user who has input before and the current user are the same, the security risk can be reduced.

  According to the present invention, there is provided a program, an input form control method, and a data processing device capable of reducing a re-input load while avoiding a security risk even when an unintended end occurs during input of an input form. can do.

<Embodiment 1>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a functional configuration of the data processing apparatus 1 according to the present embodiment. The data processing device 1 is a data processing device such as a tablet personal computer, a notebook personal computer, or a smartphone. The data processing device 1 is configured to be accessible to an arbitrary server device (including the web server 2) and the like via a network.

  The web server 2 receives a request from the data processing device 1 and transmits web content corresponding to the request to the data processing device 1 via the network.

  The data processing device 1 includes a control unit 10, a display unit 13, an input interface 14, and a storage unit 15. The data processing apparatus 1 also includes a CPU (Central Processing Unit), various circuits for network communication, and the like (not shown) as appropriate (various memories, circuits, etc. included in a so-called general personal computer). The data processing device 1 is a device that can be shared by a plurality of users. For example, when the data processing apparatus 1 is used in a medical field, the data processing apparatus 1 may be shared by doctors, nurses, and the like.

  The display unit 13 is a display that displays a so-called display screen. The input interface 14 is an interface that receives input from the user, and is, for example, a button, a knob, a track wheel, or the like. The display unit 13 and the input interface 14 may have an integrated configuration (a so-called touch panel).

  The storage unit 15 is a storage device provided in the data processing device 1. The storage unit 15 is a concept including a hard disk drive provided in the data processing apparatus 1 and a cache memory for storing temporary data.

  The control unit 10 controls communication with the web server 2 and controls the screen displayed on the display unit 13. The control unit 10 is a processing unit including a so-called web browser function, and performs acquisition of web content from the web server 2, analysis of web content, display control, and the like. Various processes of the control unit 10 are realized by a CPU (not shown) reading an arbitrary program from the storage unit 15 and executing it. In the following description, an example of handling a web application for patient management in a hospital will be described.

  The control unit 10 performs an authentication process for using the web content supplied by the web server 2. More specifically, the control unit 10 transmits a login name and password input by a medical worker (such as a doctor or nurse) to the web server 2. The web server 2 compares the received login name and password with the authentication information stored therein, and provides web content related to the top screen to the control unit 10 if the user is a legitimate user. If the login is successful, the control unit 10 (form control unit 11) continues the process while retaining the logged-in user information (for example, login name (user ID)). The retention of user information may be realized by using a known mechanism such as storage in a web storage or an HTTP session.

  A medical worker operates a web browser and performs arbitrary screen transitions. A form control unit 11 and an acquisition unit 12 in the control unit 10 are processing units for handling web content including an input form supplied from the web server 2. The acquisition unit 12 writes data (cache information) in which the input data to the input form is associated with the user information being operated in the storage unit 15. When re-displaying the input form, the form control unit 11 sets the input data written in the storage unit 15 as a default value when the user who made the re-display request corresponds to the user information written in the storage unit 15. Set as input form.

  The details of the processing of the input form included in the web content will be described below. First, referring to FIG. 2, an example of an input form to be displayed by the data processing apparatus 1 is shown. The input form is an input form in the application for patient management in the hospital, and inputs various information (“height”, “weight”, “gender”, etc.) of the patient (“Kotaro” in this example). Field f1 to f6. The input form shown in FIG. 2 is merely an example, and other input items (for example, “hospital ward”) may be provided as appropriate. In addition to a text input field, a selector or the like may be provided as appropriate. The medical worker presses the button b1 after the input is completed, and instructs the transmission of the input content.

  The medical staff inputs each field f1-f6. In this example, the fields f1 to f4 are input, and the fields f5 and f6 are not input.

Here, an unintended end of the web application may occur while the input form is being input (before the button b1 is pressed). The following is an example of termination that may occur during entry of the input form.
A medical worker erroneously presses the home button of the data processing device 1 (assuming a tablet personal computer) and terminates the web application.
・ Healthcare worker accidentally pressed the end button (x button) on the web browser.
-The battery of the data processing device 1 has dropped and all processing has been completed.
A web application session ended while a health care worker was responding to an emergency.

  As a countermeasure against the end of the unintended web application as described above, the acquisition unit 12 and the form control unit 11 execute various processes for omitting the trouble of re-inputting the input form of the medical staff.

  The acquisition unit 12 acquires input data of the input form (inputs in the fields f1 to f6 in this example) and user information (for example, login name) being operated at an arbitrary timing. In the example of FIG. 2, the acquisition unit 12 reads input data in the fields f1 to f4. The acquisition unit 12 acquires user information during login using a known mechanism such as an HTTP cookie or an HTTP session. The acquisition unit 12 may acquire user information by holding the login name input at the time of authentication to the web server 2. The acquisition unit 12 may hold a login name at the start of use of the computer and use the login name as user information.

  The acquisition unit 12 writes information (cache information) in which the acquired input data (in this example, inputs in the fields f <b> 1 to f <b> 6) and the operating user information are associated with each other in the storage unit 15. An example of a table managed by the storage unit 15 is shown in FIG.

  The table shown in FIG. 3 includes user information, form identification information, and input data. In this example, the acquisition unit 12 acquires “doctor_X” as user information (a logged-in user). Furthermore, the acquisition unit 12 acquires identification information of the input form (for example, the NAME attribute of the HTML form tab). Further, it is assumed that the acquisition unit 12 acquires the input shown in FIG. 2 as input data. Then, the acquisition unit 12 writes the user information, the input form identification information, and the input data in the storage unit 15 (table shown in FIG. 3).

  In the example of FIG. 3, for the input form “form_preoperative_patient A”, data input by the user “doctor_X” regarding height, weight, age, and sex is stored in the table (storage unit 15).

The timing of acquisition of input data (inputs in the fields f1 to f6 in this example) to the input form of the acquisition unit 12 and writing to the table may be arbitrary, but may be executed at the following timing, for example.
-When the cursor moves from one input item (field) to another input item (field)-Every elapse of a certain time (30 seconds)-When a temporary save button (not shown) is pressed

  Next, an operation when a redisplay of the input form is requested after the unintended web application is terminated will be described. The form control unit 11 determines whether the identification information of the input form included in the web content to be displayed is included in the form identification information (FIG. 3) of the table in the storage unit 15 for each transition of the web content. That is, the form control unit 11 determines whether or not cache information related to the input form to be displayed is stored in the storage unit 15.

  When the cache information related to the input form to be displayed is stored in the storage unit 15, the form control unit 11 corresponds to the current logged-in user and the user information in the table in the storage unit 15 (FIG. 3). It is determined whether or not to do. When the user responds (that is, when there is data previously input to the input form by the same user), the form control unit 11 reads the input data from the table (FIG. 3) in the storage unit 15 and reads the read data. Set as default value of input form. Note that the form control unit 11 may display a confirmation screen for confirming whether or not to use the read data as a default value before setting the default value in the input form (described later with reference to FIG. 5). .

  On the other hand, when the user information does not correspond, the form control unit 11 does not set a default value. Note that when another user is editing the same input form from the same data processing device 1, the form control unit 11 warns that the editing is being performed (described later with reference to FIG. 5). May be displayed.

  The operation of the form control unit 11 will be further described by taking the input form of FIG. 2 and the table of FIG. 3 as specific examples. Hereinafter, it is assumed that the current login user is “doctor_X” and displays web content including an input form (“form_preoperative_patient A”). The form control unit 11 reads input data whose user information is “doctor_X” and whose input form is “form_preoperative_patient A” from the table (FIG. 3). In the data example of FIG. 3, the form control unit 11 reads data of “height = 175.0”, “weight = 75.0”, “age = 36”, and “gender = male”. The form control unit 11 sets the read data as the default value in the input form. Thereby, the medical worker starts work in a state where the height or the like is displayed in advance when the input form is displayed again (input state shown in FIG. 2).

  Subsequently, it is assumed that the current login user is “doctor_Z” and the input form displays web content including “form_preoperative_patient A”. The form control unit 11 determines that the user information is “doctor_Z” in the table (FIG. 3) and that there is no input data regarding the input form “form_preoperative_patient A”. If there is no input data, the form control unit 11 does not read data from the table (FIG. 3).

  Note that the form control unit 11 may perform control to warn that another user's cache remains. Assume that the current login user is “doctor_Z” and displays web content including an input form (“form_preoperative_patient A”). The form control unit 11 determines that there is data being input for “doctor_X” instead of “doctor_Z” for the input form “form_preoperative_patient A” (FIG. 3). In this case, the form control unit 11 may display a warning screen that warns that there is data being input by another user “doctor_X” (described later with reference to FIG. 5).

  A specific example of screen transition will be described with reference to FIGS. FIG. 4 shows a first example of screen transition using the cache mechanism of the input form of the data processing apparatus 1. The medical staff is inputting the input form while logging in with the login name “doctor_X” (FIG. 4A). The acquisition unit 12 writes the input data of each field of the input form in the storage unit 15 in association with the login name “doctor_X” during user input.

  After that, it is assumed that the web application is terminated due to an unintended cause (for example, pressing of the home button of the tablet personal computer).

  After this unintended end, it is assumed that the same medical worker displays a login screen (FIG. 4B) and logs in again with the login name “doctor_X”. Then, the medical staff requests redisplay of the input form. The form control unit 11 reads the input data (height, weight, gender, age) input during the operation with the login name “doctor_X” from the storage unit 15 and sets it as the default value in the input form (FIG. 4 (C )). Thereby, the medical worker can resume the input process from the previous state.

  On the other hand, it is assumed that another medical worker operates the data processing apparatus 1 and logs in with the login name “doctor_Z”. In this case, the form control unit 11 determines that there is no input data corresponding to the login name “doctor_Z”, and displays the same input form as that displayed for the first time (FIG. 4D).

  FIG. 5 shows a second example of screen transition using the cache mechanism of the input form of the data processing apparatus 1. The operations in FIGS. 5A and 5B are the same as the operations in FIGS. 4A and 4B. When using the data processing apparatus 1 and logging in with the same login name “doctor_X” as before unintentional termination, the form control unit 11 uses the input data (height, weight, gender, Read age). Then, the form control unit 11 displays a confirmation screen for confirming whether or not the read data is set as a default value (FIG. 5C). When instructed to set as a default value (when “continue input” is pressed), the form control unit 11 displays an input form indicating the previous state as shown in FIG. When instructed not to set as a default value (when “Clear” is pressed), the form control unit 11 displays the same input form as that displayed for the first time.

  When using the data processing device 1 and logging in with a login name “doctor_Z” that is different from that before unintentional termination, the form control unit 11 uses the input data (height, weight, gender) entered during operation with “doctor_Z”. , Age). Further, the form control unit 11 determines that there is input data being input by another user (“doctor_X”) in the input form to be displayed. In this case, the form control unit 11 displays a warning screen (FIG. 5D) informing that another user was in the middle of editing.

  The web server 2 (FIG. 1) described above appropriately creates web content including a script for defining the operations of the acquisition unit 12 and the form control unit 11 and transmits the web content to the data processing device 1.

  Next, effects of the data processing apparatus 1 according to the present embodiment will be described. As described above, the acquisition unit 12 writes user information and input data to the input form in the storage unit 15 in association with each other during input of the input form by a certain user. The form control unit 11 determines whether there is any data being input to the same input form when the input form is displayed again. Then, the form control unit 11 provides an input form in which the data being input is set as a default value only when the user who has input before corresponds to the user who is currently operating (FIG. 4 ( C)). Thereby, the medical staff can continue the input in a state where the data being input is restored even when the unintended application ends. That is, it is possible to greatly reduce the labor of input by the medical staff. In addition, since the data is restored only when the user who has input before and the current user are the same, the security risk can be reduced.

  In addition, a confirmation screen may be displayed before data restoration (FIG. 5C). Thereby, it is possible to perform an appropriate input depending on whether or not the input operation that has been performed before is remembered.

(Modification 1)
Hereinafter, modifications of the above-described data processing apparatus 1 will be described. In the first modification, the form control unit 11 prohibits writing of cache information related to a plurality of users into the storage unit 15 (duplication is prohibited). Hereinafter, differences from the above configuration will be described.

  In the following description, description will be made on the assumption of the data example of FIG. When the input form “form_preoperative_patient A” is operated with the login name “doctor_Z”, the acquisition unit 12 determines that a data string (“doctor_X”) regarding the same input form exists. . When there is a data string related to the same input form, the acquisition unit 12 writes only the data string “doctor_X” or “doctor_Z” in the storage unit 15 for the input form “form_preoperative_patient A”. Control to be in the state.

  Hereinafter, control for prohibiting writing of cache information of a plurality of users to the storage unit 15 will be described. The first example is a case where overwriting is prohibited. When the data string of FIG. 3 is already stored, the acquisition unit 12 assumes that only the data string of “doctor_X” is written in the table for the input form “form_preoperative_patient A”. In other words, the acquisition unit 12 performs control so that input data of another user (“doctor_Z”) is not written for the input form “form_preoperative_patient A” (overwriting is prohibited).

  A case of overwriting will be described as a second example of control for prohibiting writing of cache information for a plurality of users. Assume that the acquisition unit 12 has acquired input data of “doctor_Z” for the input form “form_preoperative_patient A” when the data string of FIG. 3 has already been stored. In this case, the acquisition unit 12 deletes all data strings of “doctor_X” for the input form “form_preoperative_patient A” and writes a new data string related to “doctor_Z” to the table.

  By prohibiting writing of cache information (a data string including user information and input data) for a plurality of users to a certain input form, a situation where input data by a plurality of users is mixed in the data processing apparatus 1 is avoided. be able to. Thereby, a security risk can be further reduced.

(Modification 2)
The second modification is configured to automatically delete cache information (data string shown in FIG. 3) that has passed a predetermined time or more after writing to the storage unit 15. Hereinafter, the points different from the above in the modification will be described.

  The acquisition unit 12 writes time information at the time of writing together with writing of user information and input data to the storage unit 15. FIG. 6 is an example showing a table in the storage unit 15 in the modification. The table also stores the time when the data was acquired as shown in the figure.

  A deletion unit (not shown in FIG. 1) compares the current time with the input time of each data string. When the difference between the input time of each data string and the current time is a predetermined time or more (that is, when a predetermined time or more has elapsed since the input of the data string), the deletion unit deletes the data string. An explanation will be given by taking FIG. 6 as an example. For example, it is assumed that the deletion unit deletes a data string that has passed five hours or more since writing to the table (FIG. 6). At this time, if the current time is “2017/4/2 16:00”, the deletion part is written to the four data strings (“2017/4/1 15:10” written by the operation of “doctor_X”). Delete data column). The deletion unit may be realized as a daemon that operates in the data processing apparatus 1 every predetermined time.

  With the above configuration, the previous input data does not continue to remain in the storage unit 15, so that the security risk can be improved.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiments. However, the present invention is not limited to the embodiments already described, and various modifications can be made without departing from the scope of the invention. It goes without saying that it is possible.

  For example, in the above description, a medical-related application has been described as an example, but it goes without saying that it may be applied to other types of applications. In the above description, the web application is assumed. However, similar processing may be performed by another application.

  Various processes of the control unit 10 (the acquisition unit 12 and the form control unit 11) and the deletion unit of Modification 2 can be realized as a program executed by a CPU (not shown). The program may be stored using various types of non-transitory computer readable media and supplied to a computer. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (for example, flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (for example, magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / W and semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory)) are included. The program may also be supplied to the computer by various types of transitory computer readable media. Examples of transitory computer readable media include electrical signals, optical signals, and electromagnetic waves. The temporary computer-readable medium can supply the program to the computer via a wired communication path such as an electric wire and an optical fiber, or a wireless communication path.
