Description

  The present invention relates to a technique for providing a WEB screen corresponding to a terminal.

Currently, in addition to a general personal computer (PC), an increasing number of users receive a WEB service from a tablet PC, a smartphone, or the like.
For this reason, when the user accesses the same URL, there is a desire to display an optimal WEB screen on the display screen of the accessed terminal.

  Conventionally, WEB screens for PCs and mobile terminals are prepared. When there is access from a PC, the WEB screen for PC is used. It was possible to display a WEB screen.

However, in recent years, mobile terminals have also been subdivided, and display screens of tablet PCs and smartphones have become higher in resolution than general mobile phones. For this reason, a mechanism for further subdividing and displaying a WEB screen among mobile terminals has been demanded.
On the other hand, simply providing a mechanism that can be displayed in a subdivided manner forces the WEB service provider to bear the burden of creating a plurality of WEB screens.

  Therefore, even if the WEB service provider cannot prepare a WEB screen corresponding to the display screen of various terminals, a mechanism capable of providing a similar similar WEB screen is also required.

  Patent Document 1 discloses that each screen source corresponding to one RIA (Rich Internet Application) application screen includes a minimum amount of information, and is related to the function of the RIA application screen through one representative screen source. A technique has been disclosed in which information is managed so as to improve the efficiency at the time of correcting a screen source corresponding to the same RIA application screen.

  However, the technique described in Patent Document 1 describes the size of a screen in a meta tag, and is not a technique that enables a completely different screen to be displayed for each terminal. In addition, it is necessary to define meta tags as many as the number of terminals, and it is difficult to determine in the case of terminals having similar resolutions.

  Therefore, the present invention solves the above-described problem, and provides more appropriate screen information according to the type of the terminal that requests the screen information, and is more appropriate when there is no definition of the corresponding screen information. The purpose is to provide a mechanism that can provide alternative screen information.

  The present invention is an information processing apparatus that provides a WEB service, and includes a first management unit that manages screen definition information for each type of client terminal that requests screen definition information, and instead of the requested screen definition information.

A program 212 for realizing the present invention is recorded in the external memory 211 and is executed by the CPU 201 by being loaded into the RAM 202 as necessary.
Next, the flow of processing in the embodiment of the present invention will be described with reference to FIGS.

FIG. 3 is a flowchart showing a flow of processing in the client terminal according to the embodiment of the present invention.
Here, the client terminal is any one of the PC 102, the tablet terminal 103, and the portable terminal 104 as described above.
First, in step S301, the client terminal performs a process of turning on the power according to a user instruction.
In step S302, the client terminal activates the browser according to a user instruction.

  In step S303, the client terminal accepts an instruction to access a predetermined WEB server according to a user instruction. The predetermined WEB server can be specified by the URL, and the user accesses the same URL regardless of the type of the client terminal. By accessing, a predetermined program (such as JavaScript (registered trademark)) is downloaded from the WEB server to the client terminal.

  In step S304, the client terminal obtains terminal information (a user agent character string including a browser, a version, and a platform token being used) (using JavaScript or the like). In the embodiment of the present invention, the browser is a user agent. Moreover, since it is a user agent that acquires resources on the World Wide Web using HTTP, it is also called an HTTP user agent.

  In HTTP, the identification name of each user agent is declared as a user agent character string during the request. This string is prefixed with “User-Agent:” to form part of the HTTP request. It also generally contains information such as application name, version, host operating system and language.

  In step S305, the client terminal determines whether the client terminal is a PC using the acquired terminal information (user agent character string). If Yes, the process proceeds to S309, and if No, the process proceeds to S306. Here, the PC is determined because the PC has a large difference in the resolution of the display device for each client, and the resolution of the tablet PC has recently increased, making it particularly difficult to determine the terminal. And other terminals are classified using user agent character strings.

  In step S306, the client terminal obtains resolution information (height and width at the time of browser maximum display) (by using JavaScript or the like). Note that a tablet terminal or a mobile terminal may be accessed in two modes: portrait mode (short sides are horizontal and long sides are vertical) and landscape mode (short sides are vertical and long sides are horizontal). In addition, some mobile terminals have long-side resolutions that exceed tablet terminals, so here the difference between tablet terminals and mobile terminals is significant, and there is not much difference between mobile terminals. It is assumed that “short side resolution” is acquired. As a result, the tablet terminal and the portable terminal can be accurately divided, and the terminal can be identified regardless of which mode (portrait mode / landscape mode) is accessed.

  In step S307, the client terminal compares the acquired resolution with the threshold value for determining the tablet terminal. The threshold value is defined in advance in a program (such as JavaScript) downloaded from the Web server to the client when the browser accesses the WEB server. In the embodiment of the present invention, a value (for example, 768 pixels) that is the minimum value of the short side of the tablet terminal and larger than the maximum value of the short side of the mobile terminal is used as the threshold value.

  The threshold value is used to identify the type of terminal, and various definitions can be adopted as a matter of course. For example, a threshold within a predetermined range can be used in order to divide the tablet terminal, the smartphone, and the mobile phone.

In step S308, the client terminal determines whether the acquired resolution exceeds a threshold value for tablet terminal determination. If Yes, the process proceeds to S310, and if No, the process proceeds to S311. By this determination, when it is larger than the threshold value, it is determined as a tablet terminal, and when it is equal to or lower than the threshold value, it is determined as a portable terminal.
In step S309, the client terminal requests screen information for the PC from the WEB server.
In step S310, the client terminal requests screen information for the tablet terminal from the WEB server.
In step S311, the client terminal requests screen information for the portable terminal from the WEB server.

Here, in steps S309 to S311, when the client terminal requests screen information from the WEB server, a request including information specifying the requested screen and a terminal identifier that can identify the requesting terminal type is requested. I do. The information for identifying the screen is a screen ID (the destination of the screen to be accessed and the URL), and the terminal identifier is, for example, “PC”, “Tablet”, “Mobile”, or the like. The screen information is screen definition information defined in XML format, HTML format, or the like for displaying a screen on the browser of the client terminal.
The next step S312 is processing in the WEB server and will be described with reference to FIG.

FIG. 4 is a flowchart showing a flow of processing in the WEB server in the embodiment of the present invention.
In step S401, the WEB server receives a request for screen information from the client terminal. Here, the requested screen ID and the requesting terminal identifier are received simultaneously.

  In step S402, the WEB server determines whether the requested screen definition information exists. If Yes, the process proceeds to S403, and if No, the process proceeds to S404. Specifically, using the received screen ID and terminal identifier information, a determination is made based on whether the corresponding screen definition information is defined in the definition management table managed by the WEB server. An example of the definition management table is shown in FIG.

FIG. 5 is a table showing an example of the definition management table in the embodiment of the present invention.
A screen ID 501, a terminal identifier 502, and a screen definition temple treasure 503 are managed.

For example, when “Sample1” is received as the screen ID and “Tablet” is received as the terminal identifier, it can be determined in the example shown in FIG. 5 that corresponding screen definition information exists. On the other hand, when “Sample2” is received as the screen ID and “Mobile” is received as the terminal identifier, it can be determined that there is no corresponding screen definition information in the example shown in FIG.
In step S403, the WEB server acquires screen definition information corresponding to the request from the definition management table.

  On the other hand, in step S404, the WEB server determines whether screen definition information close to the request exists. If Yes, the process proceeds to S405, and if No, the process proceeds to S406. Specifically, using the requested definition, it is determined according to the decision table managed by the WEB server whether a near screen definition exists. An example of the decision table is shown in FIG.

FIG. 6 is a table showing an example of the decision table in the embodiment of the present invention.
The requested definition 601, the close definition 602, and the displayable definition 603 are managed.

  For example, when a request is received as the screen ID “Sample2” and the terminal identifier “Mobile”, the screen definition “Mobile” does not exist in the definition management table shown in FIG. However, in this case, according to the decision table, it is determined whether screen definition information of “Tablet” that is defined to be close to “Mobile” exists in the definition management table. Here, in the example illustrated in FIG. 5, screen definition information “Tablet” is present.

  In step S405, the WEB server acquires screen definition information close to the request from the definition management table. In the case of the above example, the screen definition information of the screen ID “Sample2” and the terminal identifier “Tablet” is acquired.

On the other hand, in step S406, the WEB server acquires displayable screen definition information from the definition management table. Specifically, in the example illustrated in FIG. 5, when there is no record with the screen ID “Sample2” and the terminal identifier “Tablet”, according to the decision table, when the requested screen is “Mobile”, the definition that can be displayed The screen definition information of “PC” to be acquired is acquired from the definition management table.
Finally, in step S407, the WEB server transmits the screen definition information acquired in S403, S405, and S406 to the client terminal.

By performing the process as described above, it is possible to obtain a screen definition if there is at least one screen definition for the same URL (address for identifying the screen ID), and it is not necessary to prepare screen definitions for all terminals. Can also be operated. Therefore, the burden of creating screen definition information for a person who provides a WEB service can be reduced.
The decision table is defined by the administrator, but is determined not only because the screen size is close, but also because the operability is close.
The flow of processing in the WEB server has been described above.

Subsequently, in step 313, the client terminal acquires screen definition information from the WEB server.
In step S314, the client terminal uses the acquired screen definition information to perform a drawing process for displaying on the browser.

Finally, in step S315, the client terminal sets the width of the form to the viewport (viewport). As a result, it can be displayed on the entire browser screen.
Next, output examples of screens displayed on the browser are shown in FIGS.

FIG. 7 is a diagram showing an example of screen output for a PC in the embodiment of the present invention.
Since the PC screen 701 is often handled with a mouse or a keyboard, information is displayed in a list format, and since the display has a high resolution, a large amount of information and controls such as search are arranged.

FIG. 8 is a diagram illustrating an example of screen output of the tablet terminal according to the embodiment of the present invention.
Since the screen 801 of the tablet terminal is often operated by touching a touch panel type display, information is output assuming that the list can be operated by a touch event. The amount of information is also reduced to fit within the screen size.

FIG. 9 is a diagram showing an example of the screen output of the mobile terminal in the embodiment of the present invention.
Since the screen 901 of the portable terminal is often operated by touching a touch panel type display, like the tablet terminal, information is output as a list that can be operated by a touch event. In addition, since the screen size is smaller (resolution is lower) than tablet devices, the output information is minimized, and controls such as search are not provided.

In this way, not only can the width be adjusted depending on the screen size (screen resolution), but also the component itself can be changed in accordance with the characteristics of the terminal, and the number of display items as shown in FIGS. It can be changed.
The flow of processing in the embodiment of the present invention has been described above.

As described above, according to the present invention, the corresponding screen information is provided according to the type of the terminal requesting the screen information, and more appropriate alternative screen information is provided even when the corresponding screen information is not defined. A mechanism that can be provided can be provided.
Also, the flow of processing in another embodiment of the present invention will be described.

  In the above description, the processing of S305 to S311 shown in FIG. 3 has been described by the embodiment in which the processing is executed in the client terminal. However, the processing is not necessarily performed in the client terminal, and may be executed in the WEB server.

In the case of the embodiment implemented in the WEB server, the client terminal transmits a user agent character string and information indicating the acquired “short side resolution” to the WEB server together with a request for screen information.
The WEB server first determines whether the request source is a PC using the user agent character string.

Next, when the request source is other than the PC, the received “short side resolution” and the threshold managed by itself are used for comparison with the threshold for tablet terminal determination. Judge whether it is a terminal or a mobile terminal.
Then, as a result of each determination, the requesting terminal is specified as a PC, a tablet terminal, or a portable terminal, and then the processing from S402 shown in FIG. 4 is executed.
In addition, the flow of processing in another embodiment will be described.

  According to the embodiment of the present invention described above, by specifying a near screen definition or a screen definition that can be displayed by using a decision table, the client terminal can display a screen using at least one of the screen definition information. Is possible.

  However, there is a demand for the user to display a screen corresponding to the client terminal. For screens desired by many users, the service provider needs to prepare screen definition information.

  Therefore, in S402 shown in FIG. 4, when there is no screen definition corresponding to the request source terminal, it is stored in the database which type of terminal requested the screen definition information for which screen ID. Then, by outputting the information as statistical information later, the service provider is notified of the terminal for which the screen definition information to be additionally defined for a predetermined URL (screen ID) is intended. Will be able to.

  Although the embodiments have been described in detail above, the present invention can take embodiments as, for example, a system, an apparatus, a method, a program, or a storage medium (recording medium). The present invention may be applied to a system composed of these devices, or may be applied to an apparatus composed of a single device.
