It is a figure which shows the structural example of the electronic device in this embodiment. It is a figure which shows the structural example of the display screen in this embodiment. It is a figure which shows the example of the aspect of the display screen in this embodiment. FIG. 4 is a diagram showing an example of a setting procedure for enabling a first application to communicate with a second application in the electronic device of the embodiment; 5 is a flow chart showing an example of a processing procedure executed by a first application and a second application in relation to display of an application screen in the electronic device of the present embodiment;

FIG. 1 shows a configuration example of an electronic device 100 according to this embodiment. Electronic device 100 in the figure may be, for example, a personal computer. Also, the electronic device 100 may be a smartphone, a tablet terminal, or the like. Electronic device 100 can operate, for example, by executing an installed application program, so as to implement the function of the application.
The functions of the electronic device 100 shown in the figure are realized by executing programs by a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit) included in the electronic device 100 as hardware.

Electronic device 100 includes communication unit 101 , display unit 102 , operation unit 103 , control unit 104 , and storage unit 105 .
The communication unit 101 communicates via the network NW.
The display unit 102 displays images under the control of the control unit 104 . The display unit 102 may include, as hardware, a display device such as a liquid crystal display or an OLED (Organic Light-Emitting Diode) display. Also, the display device may be configured as a touch panel.
The operation unit 103 includes operators and input devices included in the electronic device 100, input devices connected to the electronic device 100, and the like, and receives operations performed by the user U on the operators and input devices.

The control unit 104 executes various controls in the electronic device 100 . The control unit 104 includes a first application processing unit 141 and a second application processing unit 142 .

A first application is installed in the electronic device 100 . The first application is a native application that runs on an OS (Operating System).
The first application is an application having a function of providing web advertisements to users by using a second application as a PWA (Progressive Web Apps) as will be described later. The first application, for example, switches the web advertisements provided on the application screen according to the operation or the passage of time, or directs the web browser to the provided web advertisement link according to the user's operation on the first application. You can also control access.

The first application processing unit 141 is a functional unit that implements the operation of the first application by executing the program of the first application.
The first application processing unit 141 includes an application screen generation unit 1411, a communication processing unit 1412, and a screen control unit 1413 in relation to display of display screens shown in FIGS. 2 and 3, which will be described later.

The application screen generation unit 1411 generates an application screen (first application screen) of the first application. Generation of the application screen may be performed using a GPU, for example.

The first application does not have the function of accessing the protected specific information held by the web browser. In other words, the first application itself cannot access specific information such as cookies, and it is possible to display personalized information on the first application screen based on access to specific information. Can not.
For this reason, the first application of the present embodiment uses the second application as shown in later-described FIGS. In order to display personalized web content on the second application, it is also possible to control the cooperation of the second application.
Personalization here means, for example, recommending products and contents selected by the web server based on information such as cookies, user accounts, and login information acquired by the website from the web browser, or providing them as targeted advertisements on the website. It includes doing.

The communication processing unit 1412 communicates with the second application using a network protocol. This enables the first application, which is a native application, and the second application, which cannot use the API provided by the OS, to communicate and cooperate with each other.

Web content CT is content provided on the web (network). The web content CT may be a website (web page) or the like. It also includes advertisements embedded in web pages (web advertisements).

The screen control unit 1413 performs control so that the web content displayed by the second application is embedded in the first application screen as shown in FIGS. 2 and 3, which will be described later.

A second application is installed in the electronic device 100 .
The second application is an application that can access the web content CT via the network NW and cannot use an API (Application Programming Interface) provided by the OS.
As an example, the second application is PWA. PWA runs on a web browser and is realized using HTML (Hyper Text Markup Language), CSS (Cascading Style Sheets)), JavaScript, etc., and makes websites and web-accessible web applications look like native apps. It is a technology that makes it possible to install Since PWA has a function that allows access to specific information such as cookies, it is possible to support web advertising technologies such as the display of targeted advertisements using cookies. In addition, by enabling access to cookies, it is also possible to access websites for which login information has been stored and display personalized web content.
PWAs are also capable of working offline, push notifications, full-screen display, and access to device hardware. On the other hand, PWA has restrictions on UI (User Interface) configuration and cooperation with other native applications.
A web browser installed in electronic device 100 is used to install the second application.

The second application processing unit 142 is a functional unit that implements the operation of the second application.
The second application processing unit 142 generates an application screen (second application screen) of the second application, and causes the display unit 102 to display the generated second application screen.

The storage unit 105 stores various types of information that the electronic device 100 supports. The information stored in the storage unit 105 includes application programs installed in the electronic device 100 and the like.

The first application of this embodiment has a function of displaying advertisements (web advertisements) provided on the Internet on its own application screen. Also, the first application can be operated by the user. For example, the first application can change the displayed web advertisement according to the user's operation.

However, since the first application itself does not have a function to access the protected specific information held by the web browser as described above, it accesses the Internet and displays the specific information on its own application screen. You may not embed and display personalized web advertisements or personalized web content that appears after you log in. Therefore, the first application of this embodiment uses the second application, which is a PWA, to display web advertisements within its own application window. This point will be described with reference to FIG.

FIG. 2 shows the layer structure of the display screen P displayed on the display unit 102 when the first application is running.
In the layer structure of the display screen P, the desktop screen Gdp is displayed on the lowest layer.
Also, an application screen (second application screen G2) of the second application is arranged in a layer above the desktop screen Gdp. The first application activates the second application in cooperation with its own activation. The second application screen G2 is displayed according to the operation of the second application activated by the first application.
Furthermore, an application screen (first application screen G1) of the first application is arranged in a layer above the second application screen G2 of the second application.

In the example shown in the figure, an object OBJ1 as an operation button is arranged on the first application screen G1. Although the drawing shows an example in which three objects OBJ1 are arranged, the number of objects OBJ1 arranged on the first application screen G1 is not limited. Further, the position of the object OBJ1 arranged on the first application screen G1 is not particularly limited as long as it is other than the transparent area ARt described later. Also, the object OBJ1 arranged on the first application screen G1 may be, for example, an image of a file, or something other than an operation button.

A transmissive area ARt is provided (formed) in the first application screen G1. The transmissive area ARt is an area set with a transparency different from that of the surrounding area of the first application screen G1 so that the image of the layer below the first application screen G1 can be seen through.

Since the layer below the first application screen G1 is the second application screen G2, when the user views the display screen P displayed on the display unit 102, in the transmissive area ARt, in the second application screen G2 The image of the area (effective area ARv) corresponding to the transmissive area ARt appears to be displayed. In FIG. 2, an object OBJ2 is arranged in the area corresponding to the transparent area ARt on the second application screen G2. In addition, in the figure, one object OBJ2 is arranged in the effective area ARv, but the number of objects OBJ2 arranged in the effective area ARv is not particularly limited. Also, the layout of one or more objects OBJ2 in the effective area ARv is not particularly limited.

FIG. 3 shows the display screen P seen by the user when the display screen P having the layered structure shown in FIG. 2 is displayed on the display unit 102 .
As shown in the figure, the display screen P seen by the user looks like the first application screen G1 is laid out on the entire surface. At this time, the user can see the object OBJ1 arranged on the first application screen G1.
Moreover, in the transmissive area ARt of the first application screen G1, the effective area ARv corresponding to the transmissive area ARt can be seen in the second application screen G2. Since the object OBJ2 is arranged in the effective area ARv corresponding to the transparent area ARt of the second application screen G2, the user can see the object OBJ2.

Note that the first application screen G1 may be displayed as an application window of the first application. Also, the second application screen G2 may be displayed as an application window of the second application.
In this case, if the first application screen G1 as the application window is arranged in a state smaller than the desktop screen Gdp, the application window as the second application screen is also placed in the same size and position as the first application screen G1. may be placed.

Further, when the first application screen G1 and the second application screen are displayed as application windows respectively, the first application screen G1 may be moved on the desktop screen Gdp according to the user's operation, OS control, or the like. be. When the first application screen G1 is moved in this way, the second application screen may be moved so as to follow the movement of the first application screen under the control of the first application.
Further, as described above, when the second application screen is moved so as to follow the movement of the first application screen, the transmissive area ARt in the first application screen is temporarily made opaque in correspondence with the movement. You can change the state.
For example, if the transparent area ARt remains transparent when the first application screen is moved, the second application screen is also moved following the first application screen, and is displayed in the transparent area ARt. Images may be distorted. Therefore, when the first application screen is moved, the transmissive area ARt is kept in a non-transmissive state so that the above-described image distortion is not displayed and the user does not feel uncomfortable or uncomfortable. can.

The second application screen displays a web page accessed and displayed on the Internet by the second application as the PWA. An object OBJ2 arranged on the second application screen G2 is, for example, web content as a web advertisement embedded in a web page.

As described above, in the present embodiment, on the first application screen G1 displayed by activating the first application on the electronic device 100, it is possible to display web content together with an image corresponding to the operation of the first application. can. That is, in the present embodiment, web content obtained by web access is displayed on the first application screen G1 of the first application, which is a native application that does not have a function of accessing protected specific information held by a web browser. can be displayed.

When displaying web content on the application screen of a first application that is a native application and does not have a function of accessing protected specific information held by a web browser, for example, inAppBrowser (e.g., WebView component, in-app browser etc.) can also be incorporated into the first application.
However, inAppBrowser cannot access or share specific information such as cookies of web browsers implemented by the same electronic device. For this reason, it will be impossible to use web advertising technologies such as targeted advertising using cookies, or to log in and access websites where login information has been stored to display personalized web content.

On the other hand, since the second application, which is a PWA, runs on a web browser, it is possible to share specific information such as cookies with the web browser. For this reason, the second application, which is a PWA, is used alone to provide users with advertising content using web advertising technology such as the above-mentioned targeted advertising, or to log in to a website whose login information has been stored. can access and view personalized content.
However, the actual PWA is a web browser. Therefore, in PWA, there are restrictions on the frame design of the application window as the application screen. PWA also imposes restrictions on controlling other applications and hardware. In other words, with PWA, it is difficult to control other applications and hardware with a high degree of freedom as with native applications.
For this reason, it is difficult for the PWA itself to provide the UI functions of the desired application, and for example, it is difficult to provide the user with high operability and a sufficient sense of immersion.

In contrast, in the present embodiment, the first application screen G1 of the first application, which is the native application, can be displayed as the main application screen. This makes it possible to easily implement a UI that the user wants to provide using the area of the first application screen G1.
Further, in the present embodiment, the web content displayed on the first application screen G1 is the object OBJ2 on the second application screen G2 that can be seen through the transparent area ARt. In other words, it is the web content accessed on the Internet by the second application, which is the PWA. Therefore, the object OBJ2 can be, for example, an advertisement using web advertising technology such as targeting advertisement, or an image of a logged-in website. That is, in the present embodiment, web content obtained using cookies can be displayed within the first application screen G1.

In order to display the display screen P shown in FIGS. 2 and 3 on the display unit 102, setting processing is performed to enable the second application to communicate with the first application in the electronic device 100. FIG.
With reference to FIG. 4, a setting procedure example for enabling the first application to communicate with the second application in electronic device 100 will be described.
The description of the figure will be made according to procedures 1 to 8 shown in the figure. In addition, in the following description, electronic device 100 will be exemplified by a case in which a web browser application is installed and operable in addition to the first application and the second application.
In the procedure shown in the figure, the processing corresponding to the first application is executed by the communication processing unit 1412 in the first application processing unit 141, and the processing corresponding to the second application is executed by the second application processing unit 142 executes.

Procedure 1: The first application 200 activates the second application 500 by the application control function that allows the first application to control other applications.
The first application 200 of this embodiment comprises a local server 210 for communication with the second application as PWA. Local server 210 functions as a web server within (locally) electronic device 100 . The local server 210 may be included in the function as the communication processing unit 1412 .
Also, in the present embodiment, the port number used for communication by the local server 210 is a predetermined fixed port number (fixed port number).

Procedure 2: The second application 500 accesses the local server 210 of the first application 200 using the fixed port number defined for communication with the local server 210 . In other words, the first application 200 and the second application 500 can communicate using a predetermined fixed port number.

Communication between the first application 200 and the second application 500 may use, for example, WebSocket as a scheme when performing mutual communication. In this case, WSS may be used to increase security.
Also, when accessing the local server 210 of the first application 200 from the second application 500 using the REST API, HTTP (Hypertext Transfer Protocol) may be used as a scheme. HTTPS may be used to increase security in this case.
Also, data transmitted and received in communication between the first application 200 and the second application 500 may be encrypted.

Referring to the flowchart of FIG. 5, the first application 200 and the second application 500 in the electronic device 100 of the present embodiment execute processing related to the display of the application screens illustrated in FIGS. A procedure example will be described.
In the description of the figure, the application screens of the first application 200 and the second application 500 (the first application screen G1 and the second application screen G2) are respectively displayed as application windows on the desktop screen Gdp. For example.
Also, communication between the first application 200 and the second application 500 in the process of FIG. 4 is performed using the local server 210 under the setting of the cooperation port number shown in FIG.

First, a processing procedure example corresponding to the first application 200 will be described. The processing corresponding to the first application 200 in the figure is executed by the first application processing unit 141 .

Step S100: The first application processing unit 141 activates the first application 200 in response to the occurrence of a trigger instructing activation of the first application 200 according to user operation, OS control, or the like.

Step S102: The application screen generation unit 1411 in the first application correspondence processing unit 141 generates the first application screen G1 of the first application 200 activated in step S100. The screen control unit 1413 causes the display unit 102 to display the generated first application screen G1. At this time, the screen control unit 1413 arranges the generated first application screen G1 on the desktop screen Gdp.
The size, position, etc., of the application window of the first application screen G1 displayed immediately after activation may follow a predetermined initial state, or may reflect the settings of the previous display.

Further, the screen control unit 1413 instructs the OS, for example, to display the first application screen G1 displayed in step S102 in a layer above the second application screen G2 displayed in step S202, which will be described later. set to

Step S104: Further, the communication processing unit 1412 of the first application processing unit 141 instructs the second application to start as application control executed by the first application 200 started in step S100.
That is, the process of step S104 is a control for starting the second application 500 that operates in cooperation with the first application in response to the start of the first application 200 . The second application 500 is activated in response to the activation instruction in step S102.

After instructing the activation of the second application 500 in step S104, the communication processing unit 1412 may specify the size and position of the second application screen G2 as an application window to be displayed immediately after activation. Such specification of size and position is performed in order to display the second application screen G2 within the range of the first application screen G1.

Step S106: The screen control unit 1413 determines whether or not a trigger for switching the web content displayed in the transparent area ARt has occurred.
The web content switching trigger may be generated in response to an operation performed by the user on the first application screen G1 to instruct switching of the web content. Also, the web content switching trigger may be generated in response to the elapse of a predetermined time.

Step S108: When it is determined in step S106 that a web content switching trigger has occurred, the screen control unit 1413 instructs the second application 500 to switch content as control by the first application 200 .

Step S110: After the process of step S108, or when it is determined in step S106 that the web content switching trigger has not occurred, the screen control unit 1413 causes the first application screen G1 to move on the desktop screen Gdp. determine whether or not there is
The movement of the first application screen G1 corresponding to step S110 may be performed by the user's operation, or may be performed by the control of the OS according to the display or movement of other application windows, for example. .
Further, when determining in step S110 that the first application screen G1 has been moved, the application screen generation unit 1411 changes the transmissive area ARt in the first application screen G1 during movement to a non-transmissive state. you can

Step S112: When it is determined in step S110 that the first application screen has been moved, the communication processing unit 1412 issues an instruction to move the second application screen G2 following the movement of the first application screen. Send to the second application 500 .

Step S114: Further, the first application 200 can change the position of the transmissive area ARt on the first application screen G1 according to the user's operation.
Therefore, after the process of step S112, or when it is determined in step S110 that the first application screen is not moved, the screen control unit 1413 determines whether an operation to change the position of the transmissive area ARt has been performed. do.

Step S116: If it is determined in step S114 that an operation to change the position of the transmissive area ARt has been performed, the communication processing unit 1412 follows the transmissive area ARt that is moved, and moves the active area on the second application screen G2. An instruction to move the position of area ARv is sent to second application 500 .
If the position of the transmissive area ARt is changed, for example, according to the user's drag operation, the transmissive area ARt may be made non-transmissive corresponding to the movement of the transmissive area ARt. .

Step S<b>118 : In this embodiment, the first application 200 receives an operation performed on the second application 500 . Therefore, after the process of step S116 or when it is determined in step S114 that the operation to change the position of the transmissive area ARt has not been performed, the first application processing unit 141 has received an operation to the second application 500. determine whether or not

Step S120: When the first application processing unit 141 receives an operation for the second application 500 in step S118, the first application processing unit 141 sends an operation notification to the second application 500 to notify the content of the received operation. Send to
After the process of step S120, the process is returned to step S106.

Next, a processing procedure example corresponding to the second application 500 will be described. The processing corresponding to the second application 500 in the figure is executed by the second application processing unit 142 .

Step S200: The second application processing unit 142 activates the second application 500 in response to the activation instruction from the first application 200 in step S104.

Step S202: The second application processing unit 142 displays the second application screen G2 of the second application 500 activated in step S200. For this purpose, for example, the second application support processing unit 142 generates the second application screen G2, and displays the generated second application screen on the desktop screen Gdp under the first application screen G1 displayed in step S102. Arrange in layers.
The size, position, etc., of the application window of the second application screen G2 displayed immediately after activation may follow a predetermined initial state, as in the case of the initial display of the first application screen G1. The setting when it was displayed may be reflected. Alternatively, it may be displayed in the size and position specified by the first application 200 as described above.
Also, the position of the effective area ARv on the second application screen G2 displayed immediately after activation may follow a predetermined initial state, or may reflect the setting of the previous display. Alternatively, it may be specified by the first application 200 at the time of activation this time.

Step S204: As the process of the second application 500 activated in step S200, the second application correspondence processing section 142 accesses the specific web content CT via the network NW.
The web content that the second application first accesses immediately after activation may, for example, follow a predetermined initial setting, or may be the web content accessed last during the previous operation. Alternatively, the web content may be specified by the first application 200 after the activation instruction is given in step S104. Specifying web content may be done by specifying a corresponding URL.

Step S206: The second application processing unit 142 displays the image as the object OBJ2 of the web content accessed in step S204 so as to be laid out on the second application screen G2 displayed in step S202. At this time, the position where the object OBJ2 is arranged on the second application screen G2 may be according to a predetermined initial setting, or may be the position where the object OBJ2 was last arranged during the previous operation. . Alternatively, the position may be specified by the first application 200 after the activation instruction is given in step S104.

Step S208: After the process of step S206, the second application processing unit 142 determines whether or not a content switching instruction has been received from the first application 200 in step S108.

Step S210: When determining in step S208 that a content switching instruction has been received, the second application processing unit 142 accesses the web content at the URL designated by the received content switching instruction.

Step S212: The second application correspondence processing unit 142 controls to switch the display of the web content that has been displayed in the effective area ARv of the second application screen G2 to the web content accessed in step S210 this time. At this time, the second application processing unit 142 deletes the web content object OBJ2 that has been placed in the effective area ARv, and instead places the web content object OBJ2 accessed in step S210 this time. You can do

Step S214: After the process of step S212, or when it is determined in step S208 that the content switching instruction has not been received, the second application processing unit 142 receives the screen shift instruction from the first application 200 in step S112. determine whether or not

Step S216: If it is determined in step S214 that the screen movement instruction has been received, the second application processing unit 142 moves the position on the desktop screen Gdp specified by the received screen movement instruction to the second position on the desktop screen Gdp. Move the application screen. As a result, the second application screen G2 moves while being hidden by the first application screen G1, and on the display screen P, only the first application screen G1 appears to move.

Step S218: After the process of step S216, or when it is determined in step S214 that the screen movement instruction is not received, the second application processing unit 142 receives the instruction to move the effective area ARv from the first application 200 in step S116. is received.

Step S220: If it is determined in step S216 that the instruction to move the effective area ARv has been received, the second application processing unit 142 displays the image on the desktop screen Gdp specified by the received instruction to move the effective area ARv. Set the position as the position of the new effective area ARv. As the position of the effective area ARv is changed in this way, the object OBJ2 is also moved so as to be arranged within the effective area ARv at the new position.

Step S222: After the process of step S220, or when it is determined in step S218 that the instruction to move the effective area ARv has not been received, the second application processing unit 142 receives the Determine whether or not an operation notification has been received. If it is determined that the operation notification has not been received, the process returns to step S208.

Step S224: When it is determined in step S222 that the operation notification has been received, the second application processing unit 142 executes processing corresponding to the operation content indicated by the received operation notification. After the process of step S224, the process is returned to step S208.

It may also include something that holds the program for a certain period of time, such as a volatile memory inside a computer system that serves as a server or client in that case. Further, the program may be for realizing a part of the functions described above, or may be capable of realizing the functions described above in combination with a program already recorded in the computer system. It may be implemented using a programmable logic device such as an FPGA (Field Programmable Gate Array).
