  However, since the technique of Patent Document 1 uses HTML for description of form data, for example, form data including a curve or the like cannot be expressed. In addition, it is impossible to express the rounded corners of the table used in the standard form, and it is not possible to express the interface of the standard form as it is. Also, since the detailed display of HTML may differ depending on the execution environment of the client terminal, different HTML data is generated in advance for each OS (Operating System) and browser type, or the server dynamically changes according to the request. Need to be generated, and the form design and form management become complicated, resulting in excessive operational load or processing load. In the technique of Patent Document 2, the form data cannot be displayed unless the client terminal has a display application (Adobe (registered trademark) Reader) that reads and displays data in the PDF format, and thus depends on the environment of the client terminal. In this case, if the user actively operates the client terminal and does not install the specified display application, the form data cannot be displayed, and there are cases where the version is upgraded for security even after installation. May be cumbersome.

The DIV element is secured as a vector image display area based on the vector description data generated by the vector description data generation unit 1533. The DIV element includes a form ID for identifying form definition data that defines the corresponding form. The form definition data acquisition unit 1531 described later acquires form definition data corresponding to the form ID. An HTML element or a vector element is added to the DIV element by the vector description data generation unit 1533 and stored in the HTML data storage unit 1410, thereby generating form data. In this embodiment, the form ID is defined in the DIV element. However, it may be defined in the SCRIPT element or other elements in the HTML data, and the form ID is transmitted to the form server 2000 in advance. In addition, it may be held in the storage unit 2100 until a series of operations is completed.

  The form definition data storage unit 1420 stores form definition data including form elements indicating the shape or data item of a predetermined figure. The form definition data is acquired by the form definition data acquisition unit 1531 according to the form ID included in the DIV element of the HTML data. FIG. 3 is a diagram illustrating a data example of the form definition data stored in the form definition data storage unit 1420. The form definition data is a file in which a form data structure common to a plurality of types of vector languages is defined.

  The conversion program storage unit 1430 stores a conversion program that generates vector description data corresponding to a plurality of types of vector languages based on the form definition data stored in the form definition data storage unit 1420. The conversion program is acquired from the URL of the file acquisition destination indicated by the SCRIPT element of the HTML data. Since the conversion program is operated by the client script control unit 1530, the processing content will be described in the client script control unit 1530 described later.

The control unit 1500 includes an HTML control unit 1510, a vector image control unit 1520, and a client script control unit 1530.
The HTML control unit 1510 reads the HTML data stored in the HTML data storage unit 1410, interprets and renders the read HTML data, generates image data, and displays the image data on the display unit 1100. Also, when interpreting the HTML data, the HTML control unit 1510 connects to the acquisition destination URL via the communication unit 1600 if the HTML data includes an acquisition destination URL such as an image file or a script file. get. Here, the HTML control unit 1510 acquires the conversion program indicated by the SCRIPT element of the HTML data from the form server 2000 and stores it in the conversion program storage unit 1430.

The vector image control unit 1520 generates a vector image based on vector description data described according to a vector language defined among a plurality of types of vector languages. The vector image control unit 1520 generates a vector image by interpreting any one of vector languages such as SVG and VML. As described above, the corresponding vector language differs depending on the type of web browser. Here, the vector image control unit 1520 reads the vector description data included in the DIV element of the HTML data stored in the HTML data storage unit 1410, and generates a vector image.
Thus, of the image data displayed on the display unit 1100, the HTML part is interpreted by the HTML control unit 1510, and the vector image part is interpreted by the vector image control unit 1520.

  The client script control unit 1530 executes a predetermined client script. For example, the client script control unit 1530 executes a script included in the SCRIPT element of the HTML data, a conversion program script stored in the conversion program storage unit 1430, and the like. Here, the client script control unit 1530 executes the conversion program stored in the conversion program storage unit 1430, acquires form definition data from the form server 2000 based on the form ID, and stores the form definition data in the form definition data storage unit 1420. Based on the form definition data, vector description data described in a vector language corresponding to the vector image control unit 1520 of the own apparatus is generated. The client script control unit 1530 includes functional units of a form definition data acquisition unit 1531, a vector language type determination unit 1532, and a vector description data generation unit 1533. These functional units are constituted by a conversion program read by the SCRIPT element of HTML data transmitted from the form server 2000.

  The form definition data acquisition unit 1531 communicates with the form server 2000 via the communication unit 1600, and converts the form definition data corresponding to the form ID included in the DIV element of the HTML data stored in the HTML data storage unit 1410 into the form. Acquired from the server 2000. Here, the form definition data acquisition unit 1531 uses asynchronous communication by XMLHttpRequest, which is a JavaScript (registered trademark) built-in class for performing HTTP (Hypertext Transfer Protocol) communication, and does not re-read a web page. Get definition data.

  The vector language type determination unit 1532 determines the type of vector language corresponding to the vector image control unit 1520. The vector language type determination unit 1532 determines the type of the vector language supported by the vector image control unit 1520 included in the web browser 1300 by determining the type of the web browser 1300, for example. For example, FIG. 4 is a diagram illustrating a program code example of vector language type determination processing by the vector language type determination unit 1532. The vector language type determination unit 1532 acquires, for example, user agent information of the web browser, and determines the type of vector language to be used depending on whether the acquired information includes a specific character string. Here, when the character string “MSIE” is included in the information of the user agent of the web browser, it is determined that it corresponds to the vector language of VML, and when the character string “MSIE” is not included. , It is determined that it corresponds to the SVG vector language.

  The vector description data generation unit 1533 is based on the form definition data stored in the form definition data storage unit 1420, and is a DOM (Document Object Model) tree described in the vector language according to the determination result by the vector language type determination unit 1532. To generate vector description data. The vector description data generation unit 1533 stores the generated vector description data in addition to the DIV element included in the HTML data stored in the HTML data storage unit 1410.

  FIG. 5 is a diagram showing a correspondence table of form elements in the conversion process to SVG by the vector description data generation unit 1533. FIG. 6 is a correspondence table of form elements in the conversion process to VML by the vector description data generation unit 1533. FIG. The conversion program is a program that converts a form element and generates a VML element or an SVG element based on the correspondence between the form element in the form definition data and the vector element in the vector image.

  For example, FIG. 7 is a diagram illustrating a procedure for converting form definition data by the vector description data generation unit 1533. When the form definition data as indicated by the symbol a exists, the vector description data generation unit 1533 constructs a DOM tree as indicated by the symbol b-1 using an XML parser (step S10). The vector description data generation unit 1533 converts the group element, which is an upper form element in the DOM tree, into a VML group element as indicated by reference numeral b-2 (step S11). Next, the line element which is a child element of the group element is converted into a VML line element as indicated by reference numeral c-1, and connected to the parent element generated in step S11 as indicated by reference numeral c-2 ( Step S12). FIG. 8 is a diagram showing an example of program code for conversion processing by the vector description data generation unit 1533.

For example, it is assumed that the form definition data includes the following form elements.
<line id = "form ID_ln001" x1 = "1400" y1 = "460" x2 = "1860" y2 = "460" stroke = "black" stroke_width = "1" stroke_dasharray = "solid"/>
At this time, if the vector language determined by the vector language type determination unit 1532 is SVG, the vector description data generation unit 1533 generates the following vector elements.
<svg: line id = "form ID_ln001" name = "form ID_ln001" x1 = "1400" y1 = "460" x2 = "1860" y2 = "460" stroke = "black" stroke-width = "1"/>
On the other hand, if the vector language determined by the vector language type determination unit 1532 is VML, the following vector elements are generated.
<line id = ”Form ID_ln001” name = "Form ID_ln001" from = "1400,460" to = "1860,460" strokecolor = "black" strokeweight = "1pt"></line>

  The communication unit 1600 communicates with the form server and receives HTML data, form definition data, a conversion program, and the like.

  The form server 2000 is a computer device that distributes information such as HTML data, form definition data, and conversion programs, and provides a form service to the client terminal 1000. The form server 2000 stores in advance user account information and authentication information including a combination of a user ID and a password for each user, form data generated by the user, and the like. The form server 2000 includes a storage unit 2100, a control unit 2200, and a communication unit 2300.

The storage unit 2100 stores information necessary for the form server 2000 to provide a form service. The storage unit 2100 includes an HTML data storage unit 2110, a form definition data storage unit 2120, and a conversion program storage unit 2130.
The HTML data storage unit 2110 stores HTML data distributed in response to access from the client terminal 1000.
The form definition data storage unit 2120 stores form definition data in association with each defined form ID. The form ID corresponds to the form ID included in the DIV element of the HTML data.
The conversion program storage unit 2130 stores a conversion program for generating vector description data based on the form definition data.

The control unit 2200 controls the operation of the form server 2000. For example, the control unit 2200 has a web server function and provides a website that is an interface with the client terminal 1000. For example, FIG. 9 is a diagram illustrating a log-in screen example of a form service provided by the control unit 2200. In response to access from the client terminal 1000, the control unit 2200 transmits such a login screen to the client terminal 1000 via the communication unit 2300.
The communication unit 2300 communicates with the client terminal 1000 via a network.

Next, an operation example of the form system 1 of the present embodiment will be described. FIG. 10 is a flowchart illustrating an operation example of the form data display processing by the client terminal 1000-1 of the present embodiment.
First, when the client terminal 1000 accesses the form server 2000, the control unit 2200 of the form server 2000 transmits the above-described login screen to the client terminal 1000. The control unit 1500 of the client terminal 1000 causes the display unit 1100 to display the received login screen. The input unit 1200 accepts input of login information (ID, password, form ID, etc.) from the user. The client terminal 1000 transmits login information to the form server 2000 via the communication unit 1600. The control unit 2200 of the form server 2000 reads the user account information stored in the storage unit 2100 and performs user authentication. If the authentication is valid, the control unit 2200 transmits HTML data to the client terminal 1000 via the communication unit 2300.

  Next, when receiving the HTML data transmitted from the form server 2000, the HTML control unit 1510 of the client terminal 1000 stores the HTML data in the HTML data storage unit 1410 of the storage unit 1400. Then, the HTML control unit 1510 reads the HTML data stored in the HTML data storage unit 1410 and interprets the read HTML data. Here, the HTML control unit 1510 reads out the conversion program from the conversion program storage unit 2130 of the form server 2000 in accordance with the script acquisition destination URL indicated in the SCRIPT element included in the HTML data, and stores it in the conversion program storage unit 1430. Let

  Then, the form definition data acquisition unit 1531 reads out the form definition data corresponding to the form ID from the form definition data storage unit 2120 of the form server 2000 using the form ID indicated by the DIV element included in the HTML data as a key, and forms definition The data is stored in the data storage unit 1420 (step S1). The vector language type determination unit 1532 acquires the user agent information of the web browser of the web browser 1300 of the own device, and determines the vector language corresponding to the own device (step S2).

  Then, the vector description data generation unit 1533 generates vector description data based on the form definition data stored in the form definition data storage unit 1420 according to the determination result by the vector language type determination unit 1532. For example, if it is determined in step S2 that the vector image control unit 1520 of the device itself is compatible with VML (step S2: VML), the vector description data generation unit 1533 generates VML vector description data based on the form definition data. The generated vector description data is added to the HTML DIV element stored in the HTML data storage unit 1410 and stored (step S3). If it is determined in step S2 that the vector image control unit 1520 of the device itself is compatible with SVG (step S2: SVG), the vector description data generation unit 1533 generates SVG vector description data based on the form definition data. Then, the generated vector description data is added to and stored in the HTML DIV element stored in the HTML data storage unit 1410 (step S4).

  The HTML control unit 1510 generates image data corresponding to the HTML element included in the HTML data stored in the HTML data storage unit 1410, and the vector image control unit 1520 stores the HTML data stored in the HTML data storage unit 1410. A vector image corresponding to the vector description data included in the DIV element is generated. The control unit 1500 combines the image data generated by the HTML control unit 1510 and the vector image generated by the vector image control unit 1520 and causes the display unit 1100 to display them (step S5).

  As described above, according to the form system 1 of the present embodiment, the client terminal 1000 performs processing using a client script that is commonly used in various types of web browsers, and displays a vector image included in the web browser. Since the vector image is displayed using the function, it is possible to display the form data in a highly expressive manner and without depending on its own environment. That is, the user does not need to perform operations such as installing a special application such as a plug-in or upgrading the version in order to display the form data on the client terminal 1000. As described above, according to the present embodiment, the client terminal 1000 automatically acquires the conversion program without performing any special operation, and the conversion program is automatically executed on the client side. Can generate and display form data according to Further, since the generated form layout is generated as a vector image, it is possible to display a form as it is viewed from the same form as a form layout that has been conventionally created on a paper medium. Further, since the vector description data is generated in the client terminal 1000, it is not necessary to store or generate various types of form information on the form server 2000 side, and the server load or the operation load can be reduced.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. The form system 1 of this embodiment is the same as that of the first embodiment, and the characteristic points of this embodiment will be described below. In the present embodiment, the form definition data transmitted from the form server 2000 to the client terminal 1000 includes a form element that accepts data input. The conversion program converts a form element that accepts data input into a vector element indicating an area (data input acceptance area) that accepts data input and an input form description element of XHTML (Extensible HyperText Markup Language) that accepts data input. A program is included. Then, the vector description data generation unit 1533 of the client terminal 1000 generates a vector element indicating a data input reception area and an XHTML input form description element for receiving data input, and displays them on the display unit 1100. Here, XHTML is used as an input form description element. However, elements such as XForms and WebForms may be used when the browser can interpret them, without being limited to XHTML or HTML elements.

FIG. 11 is a diagram illustrating a conversion example when the form definition data includes an input item. FIG. 11A is a diagram showing an example of a form element (textfield) that accepts data input. FIG. 11B-1 is a diagram showing an example of vector description data (VML) in which form elements that accept data input are converted and XHTML data that accepts data input. FIG. 11B-2 is a diagram showing an example of vector description data (SVG) in which a form element that accepts data input is converted and XHTML data that accepts data input.
FIG. 12 is a diagram illustrating a display example of a vector image including input items. Here, the vector element indicating the data input reception area is displayed in gray on the form data of the vector image, and the input is accepted by the text input function of the XHTML data.
As described above, according to this embodiment, it is possible to accept data input according to the form data displayed on the display unit 1100, and information input to the form data can be completed on the network.

<Third Embodiment>
Next, a third embodiment of the present invention will be described. The client terminal 1000 according to the present embodiment converts input information into a vector element when input information is input by an input function of XHTML data that accepts data input such as a text box in the second embodiment. .
Here, when processing to convert a form element that accepts input into a vector element indicating a data input acceptance area and an XHTML input form description element that accepts data input such as a text box, a new element is entered after the text box is entered. Set to call the conversion program. For example, FIG. 13 is a diagram illustrating an example of vector description data and conversion program code when converting vector description data according to an event. In this case, as shown in FIG. 13A, an instruction to operate a new transformation program called “transforminput” on an input form description element of XHTML embedded in a vector element, for example, at an onblur event (an event indicating a loss of focus) Is described. Then, as shown in FIG. 13B, in the SCRIPT element, the input text is converted into a vector element text element, and a new function having a function of hiding (hiding) the text box generated by the XHTML data. The transformation program (transforminput).

FIG. 14 is a diagram illustrating a display example in the case where the data input to the input form description element of XHTML is converted into a vector image. FIG. 14A is a view showing a display example of input form descriptors required for XHTML before conversion and data input to XHTML. Here, when the focus is moved from the text box to another control with a mouse, a tab key, or the like, the display is as shown in FIG. FIG. 14B is a diagram illustrating a display example of the vector image after conversion.
As described above, according to the present embodiment, since the input content is converted into a vector image instead of text, the entire form data can be easily enlarged or reduced.

<Fourth Embodiment>
Next, a fourth embodiment of the present invention will be described. The form system 1 of this embodiment is the same as that of the first embodiment and the second embodiment, and characteristic points in this embodiment will be described below. The vector description data generation unit 1533 in the present embodiment generates vector description data in which form elements in the form definition data are enlarged or reduced. That is, it is possible that the form data includes many items, or that the text and input fields become smaller when the entire form data is displayed. Therefore, the form data is enlarged or reduced.

  Here, in the HTML data transmitted by the form server 2000, for example, as shown in the upper part of the screen of FIG. 12, a button for accepting enlargement or reduction is displayed in advance, and the event corresponding to the pressed button is displayed. Then, a program for updating the tag of HTML data or vector description data embedded in the DIV element is described in a numerical value corresponding to the enlargement ratio or reduction ratio of the pressed button. When the user presses the enlargement or reduction button, the vector description data generation unit 1533 updates the DOM tree of HTML data or vector description data in response to this event.

  Here, for example, the vector description data generation unit 1533 sets initial display values as default_size attributes and default_font_size attributes in the HTML elements in the HTML data or the vector elements in the vector description data, and adds them to the DOM image in advance. Then, the value of each attribute is calculated according to the specified enlargement ratio or reduction ratio when the button is pressed, and the vector image is enlarged / reduced based on this value, and the font is enlarged / reduced. . Here, the enlargement / reduction of the font can be omitted depending on the type of the vector image.

  For example, when converting from 2 times to 3 times in VML, the WIDTH and HEIGHT in the group tag's style attribute are changed to expand / reduce the vector element, and the FONT-SIZE in the style attribute of the textarea tag. , FONT-SIZE in the style attribute of the input tag is changed to the same magnification. By simultaneously changing the magnification in this way, the entire form can be enlarged or reduced. FIG. 15A is a diagram illustrating an example of vector description data before conversion by the vector description data generation unit 1533. FIG. 15B is a diagram illustrating an example of vector description data after conversion by the vector description data generation unit 1533. Here, for example, the WIDTH attribute shown in the first line is converted from 1200 px to 1800 px.

Alternatively, for example, a ZOOM attribute indicating a numerical value of the enlargement ratio or reduction ratio may be set in the vector element, and the size of the vector element may be changed according to the set value of the ZOOM attribute.
Thus, according to the present embodiment, for example, vector elements including input items can be enlarged / reduced. Therefore, when inputting information to form data, it is small and difficult to input if the entire form is displayed. In some cases, it is possible to input information by enlarging a vector image and an XHTML image for accepting input, and it is also possible to restore the original size after input.

  As described above, according to the present embodiment, for example, conventionally, form data downloaded by a client terminal is printed on a paper medium, a user fills in necessary items and mails it, or a form server is sent from a client terminal via a network. Even if the received information is printed on paper media of a specified form and mailed to the user for paperwork, the network is not used in combination with such information communication and paper media mailing. It is possible to complete the paperwork only by communication via the network, and to perform the form processing more efficiently.

  It should be noted that a program for realizing the function of each processing unit in the present invention is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed to perform form processing. You may go. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer system” includes a WWW system having a homepage providing environment (or display environment). The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Further, the “computer-readable recording medium” refers to a volatile memory (RAM) in a computer system that becomes a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. In addition, those holding programs for a certain period of time are also included.

  The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, what is called a difference file (difference program) may be sufficient.
