1 is a block diagram illustrating a configuration of a switch-back user interface (UI) providing apparatus according to an embodiment of the present invention.

In the present invention, the switchback UI refers to a user interface for directly moving from an application being used by a user to another application or for directly loading content that is being viewed and other content, in conjunction with a scroll end event.

Referring to FIG. 1, the switchback UI providing apparatus 100 may include a touch screen 110, a processor 120, a storage unit 130, and a communication interface unit 140. Although only the components related to various embodiments of the present invention are described in this specification, general knowledge in the technical field to which the present invention pertains may be included in addition to the components illustrated in FIG. 1. Anyone who has it can understand it.

The apparatus 100 for providing a switchback UI according to the present invention may be implemented as a mobile phone, a smart phone, a laptop computer, a digital broadcasting terminal, a portable game terminal, PDA (Personal Digital Assistants), a navigation device, a tablet, and the like. However, the present invention is not limited thereto, and may be applied to any type of computing device having a touch screen.

The touch screen 110 is a device that receives a user input through a screen displayed with output of information, and may be composed of a display unit 112 and a touch input sensing unit 111.

The display unit 112 displays information on the touch screen 110 according to the control signal of the processor 120. The content displayed on the display unit 112 may be at least one of a list of items, a document, a web page, text, and an image. The screen displayed on the touch screen 110 may be composed of one or more frames. A frame is a screen divided into a predetermined area so that desired information can be displayed at a predetermined location on the screen.

When information to be displayed in one frame exceeds the size of the frame, information not displayed in the frame may be displayed through scrolling of the screen. The direction of the scroll can be vertical, horizontal, diagonal or rotational. A scroll range, which means a scrollable range, may be determined according to the length of content in a corresponding scroll direction. That is, the scroll range may be from one end of the content in the scroll direction to the other end.

The touch input sensing unit 111 converts state changes of sensors, such as a pressure change applied to the surface, a change in electrostatic capacity, or a change in light amount, into an electrical signal by using a sensor provided on the surface of the touch screen 110, Touch input can be detected. The touch input detection unit 111 may detect a user's touch, movement of a touch input, and a touch input pattern.

Further, the touch input detection unit 111 may be based on the state change of the sensors, the position of the touch input, the duration of the touch input, the start position, the end position, the moving direction, the moving distance of the touch input when moving and moving the touch input, or Movement speed, etc. can be further sensed. For example, the touch input detection unit 111 may include drag, flick, tap, touch and hold, double tap, panning, and sweep ( sweep).

The touch input detection unit 111 transmits the sensed touch input to the processor 120, and the processor 120 performs predetermined function processing corresponding to the touch input.

The touch input detection unit 111 may detect a scroll input for the frame area based on the touch input on the touch screen 110. For example, a touch input dragging from one point on the touch screen 110 to another point may be recognized as a scroll input.

The storage unit 130 stores data and programs necessary for the operation of the device 100. The storage unit 130 is not limited to a specific type, and includes various types of hard disk drives (Hard Dick Drive, HDD), read only memory (ROM), random access memory (RAM), flash memory, and memory cards. It may include at least one of the storage medium.

The processor 120 controls the overall operation of the device 100, including the operation of the touch screen 110. The processor 120 executes the application stored in the storage 130 and displays the content in the frame area on the touch screen 110 and moves the content within the frame area according to the scroll direction of the scroll input. When the scroll input continues and the end of the scroll range is reached, the processor 120 generates a scroll end event, and stops moving the content at a position where the end of the scroll range touches one surface of the frame area.

In the present invention, the processor 120 executes a dedicated application that provides a switchback UI as a background, and this dedicated application intercepts a scroll termination event in any application and basically processes the OS according to the scroll termination. Instead, or in addition to this basic processing, a switchback UI is created and displayed.

The processor 120 displays a screen of the currently running first application on the touch screen 110, and when a scroll end event occurs on this screen, a UI element that can move to at least one second application associated with the first application After dynamically configuring a switchback UI including (User Interfac Element), the display is overlaid on the screen of the first application. The position to display the switchback UI is preferably the edge of the screen facing the user's gaze while scrolling.

At this time, when the switchback UI is slightly lowered or raised to show only a part, and within a certain period of time, an event where the scrolling ends, such as pulling or lowering or raising, occurs once more, or when a predetermined user interaction is input, such as touching a partially displayed switchback UI , Switchback UI will be converted into a complete form and displayed.

That is, first, the first type of switchback UI including a part of the switchback UI is displayed on the touch screen 110, and when a predetermined user interaction is input to the first type of switchback UI, the entire switchback UI is displayed. It can be controlled to display the switchback UI of the second form including the touch screen (110).

In the present invention, the UI element represents an element constituting a switchback UI, such as an icon, text, image, button, etc. that includes link information or shortcut information that can be moved to a predetermined application or content, and one switchback UI It will include the above UI elements.

For example, the switchback UI may be generated as a list of icons corresponding to an application frequently used by the user in the device 100, or an advertisement image including link information to other applications that provide a service associated with the currently running application. It can be configured to include. Alternatively, it may be configured to include link information for content related to information provided by an application executed in the foreground or link information of an application providing the content.

The second form of the switchback UI displays the entire switchback UI, and the first form refers to a form in which only a part of the switchback UI is displayed to imply to the user what information the switchback UI contains.

According to an embodiment of the present invention, the switchback UI providing apparatus 100 may further include a communication interface unit 140. The communication interface unit 140 is a module that allows data to be transmitted and received with the server 150 supporting a switchback UI providing service through a wired or wireless network. The communication interface 140 is also used when an application executed in the switchback UI providing device 100 accesses an external site or device. At this time, the network may include the Internet, a mobile communication network, a local area network (LAN), a wireless LAN, a wide area network (WAN), etc., but is not limited thereto, and any type of network may be used.

The switchback UI providing device 100 may grasp information about an application that is currently running and scrolling on the screen to dynamically configure the switchback UI, and then transmit the information to the server 150 through the communication interface 140. In response, metadata about a corresponding application may be received from the server 150, and by using this, at least one of a type of a switchback UI, a UI element to be included in the switchback UI, and information to be displayed on the switchback UI may be determined.

Various embodiments for providing the switchback UI will be described in more detail below with reference to FIGS. 2 to 8.

2 is a flowchart illustrating a method for providing a switchback UI according to an embodiment of the present invention, and FIG. 3 is an example of a screen for explaining a process of invoking a switchback UI, and an application executed by a user in the foreground A dedicated application running in the background separately provides a switchback UI using the information of the application running in the foreground.

Referring to FIG. 2, in step S20, a first application is executed according to a user's operation.

As shown in (a) of FIG. 3A, when a scroll input is detected in a predetermined frame area of the first application 300, the processor 120 moves content according to the scroll direction and displays it on the touch screen 110. In this example, the screen is scrolled downward by dragging upward.

In step S21, when a scroll end event occurs due to reaching the end of the scroll range during scroll processing, information about the first application is acquired. The information about the scrolling first application may include at least one of the name, purpose, function, provider of the first application, the type of information that the application is displaying on the screen, and content of the information.

In step S22, a custom switchback UI dynamically configured according to a situation is generated using the first application information obtained as described above. Specifically, the dedicated application dynamically configures a switchback UI including a UI element that can move to at least one second application associated with the first application using the first application information.

Dynamically configuring the switchback UI is intended to provide convenience and satisfaction to the user by configuring the switchback UI differently depending on the situation, such as which application the user is using and what content the user is viewing through the application.

According to an embodiment of the present disclosure, a database in which a predefined application and configuration information of a switchback UI corresponding to a user terminal are frequently generated is generated in the storage unit 130 and dynamic configuration of the switchback UI can be performed using the database. . The configuration information of the switchback UI may include at least one of a type or type of the switchback UI, information on a UI element to be included in the switchback UI, and information to be displayed on the switchback UI.

In the above embodiment, the dedicated application may retrieve the configuration information of the switchback UI corresponding to the first application that the user is scrolling from the database, and generate the switchback UI using the retrieved configuration information.

According to an embodiment, a method of receiving support from the external server 150 may be used for dynamic configuration of the switchback UI. The dedicated application acquires information about the first application that the user is scrolling and transmits it to the server 150, and in response receives metadata of the first application from the server 150.

The metadata may include information about at least one UI element to be included in the switchback UI, a content or information to be provided by the switchback UI, or a type of switchback UI to be provided corresponding to the corresponding application. The dedicated application uses the metadata received from the server 150 to determine at least one of the type or type of the switchback UI, the UI elements to be included in the switchback UI, and information to be displayed on the switchback UI, and accordingly the switchback Create UI.

According to one embodiment, for the dynamic configuration of the switchback UI, the content of information provided by the scrolling application may be referred to.

In the above embodiment, the dedicated application acquires the content of the information by reading and parsing the information displayed on the screen on which the first application was executed, and after determining the content to recommend in relation to the content of the obtained information, provides the recommended content A switchback UI including a UI element for doing so may be generated.

According to one embodiment, user preferences may be used for dynamic configuration of the switchback UI. For example, it is possible to determine which application (s) the user has recently used, and create a switchback UI including UI elements representing link information related to these second applications.

In step S23, the edge position of the switchback UI to be displayed on the screen is determined according to the direction of scrolling performed on the screen (frame area being scrolled) of the first application. For example, if scrolling is being performed in the downward direction of the screen, the switchback UI is displayed at the bottom edge of the screen, and when scrolling is being performed in the upward direction of the screen, the switchback UI is displayed at the upper edge of the screen.

Additionally, the format of the switchback UI can be determined according to the direction of scrolling. The switchback UI includes an area to be previewed, and determines where to paste the preview area according to the scroll direction.

For example, if the switchback UI is generated in a format in which the preview area is attached to the top of the switchback UI when the scroll direction is the screen downward direction, the first form including only a part of the switchback UI at the bottom edge of the screen where scrolling ends When is displayed, the preview area will appear on the screen and the rest of the area will be hidden.

As another example, if the switchback UI is generated in a format in which the preview area is attached to the bottom of the switchback UI when the scrolling direction is on the screen, the first form including only a part of the switchback UI at the top edge of the screen where scrolling ends is shown. When displaying, the preview area will appear on the screen and the rest of the area will be hidden.

In step S24, the switchback UI is displayed in the display position and / or format determined as described above, but is displayed in a first form including only a part of the switchback UI, that is, the preview area.

As illustrated in (b) of FIG. 3A, when the user continues scrolling input and reaches the end of the scrolling range, the first type of switchback UI 320 including a part of the dynamically configured switchback UI 320 is displayed on the screen. In this example, it can be seen that the first form 320 of the switchback UI is displayed on the lower edge corresponding to the scroll direction.

If the user is interested in seeing the first type of switchback UI 320, as shown in (c) of FIG. 3B, an input such as touch will be performed.

On the other hand, before displaying the first type of switchback UI 320 in response to the scroll end event, a specific indication indicating the end of the screen content may be displayed so that the user can easily recognize that the scroll has ended.

In step S25, when a predetermined user interaction, such as additional scroll input or touch, is input, a switchback UI of the second type including the entire switchback UI is converted and displayed. The second type of switchback UI 330 will be displayed in a size showing the entire UI element to be provided as shown in FIG. 3D (d).

As described above, if there is user interaction within a predetermined time, the entire function of the switchback UI is displayed, but if there is no user interaction within a predetermined time, the user determines that the user is not interested in the switchback UI, and then switches the UI By disappearing to the corresponding edge, the user's convenience can be promoted.

Referring to (a) of FIG. 4, when a scroll input event of the user is detected and scrolled to the end of the scroll range in the first application execution screen 400 providing an instant messaging service, a scroll end event occurs, the switchback is responded thereto The UI is generated and displayed in the preview form 410 at the bottom left of the screen.

In this example, the switchback UI corresponding to the first application is a second application preferred by the user, a second application frequently used by the user, and / or a second application that the user has called next after using the first application It is predefined to include icons that can be moved directly to, and an image guiding which switchback UI is available is displayed as the first form 410 of the generated switchback UI.

As shown in (b) of FIG. 4, when a user inputs a predetermined interaction, the second form 410 showing the entire switchback UI is converted, and the second form switchback UI 420 is another application. It includes icons (421, 422, 423, 424) that can be moved directly to. When the user touches and selects one of these icons, a corresponding second application is executed and can be used immediately.

On the other hand, the second application is executed according to the user's selection on the switchback UI that appears at the end of scrolling on the first application screen, and when the second application is closed, the focus returns to the switchback UI again.

At this time, the switchback UI may transfer the value returned from the operation of the second application that was called to the first application that was executed in the existing foreground.

Specifically, after capturing the screen of the second application and generating link information associated with the captured screen, when returning to the first application from the switchback UI, the link information generated as described above is returned to the first application. 1 It can be controlled to be displayed on the screen of the application.

Referring to FIG. 5, when the user uses the search engine application 500 called through the switchback UI 420 and then closes or reopens the switchback UI 420, focus is shifted to the switchback UI 420. At this time, the search result screen generated by the second application 500 is captured and link information associated with it is generated. Subsequently, when the focus is switched to the first application 400 by touching the first application 400 or exiting the switchback UI 420, a conversation 510 including the captured screen 511 and link information 512 ) Will be automatically entered into the first application 400.

In addition, if there is a component having focus in the first application 400 that was previously executed, when the switchback UI 420 is executed, the focus is stored on the first application 400 and then the switchback UI 420 is stored. When returning to the first application 400 after termination, the return value from the second application 500 may be delivered to the component that originally had the focus.

For example, when the focus is on the instant message input window of the first application 400, the screen capture data and link information, which are return values from the second application 500, can be controlled to be automatically input to the instant message input window.

Referring to FIG. 6, since the user is scrolling through stored photo images in the gallery application and the type of information provided by the gallery application is a photo, a switchback UI including a UI element that can be moved to an application that provides a photo print service is provided. It is created and displayed.

In this embodiment, when the user touches 'Printing Service' in the switchback UI at the bottom of the screen, the user can go directly to the application providing the printing service.

Referring to FIG. 7, the user searches using a predetermined search term in an application capable of web browsing, and when a search result is scrolled to reach the end of the scrolling range, a switchback for providing recommended content related to the searched content The UI is created and displayed.

In this embodiment, the dedicated application parses the information provided by the web browsing application to confirm that it is content related to the air conditioner, and dynamically generates a switchback UI for providing content related to the content of this information. When the user selects the UI element 'air conditioner special offer' in the switchback UI at the bottom of the screen, the user can go directly to an application that provides air conditioner special price information.

When the user executes the first application and scrolls and the scroll end event occurs, the switchback UI is generated and displayed. In this embodiment, information on the UI element selected by the user on the switchback UI is transmitted to the server 150 , After receiving the link information associated with the UI element from the server 150, the switchback UI is terminated and the link information is transmitted to the first application to control the content corresponding to the link information to be displayed on the first application.

Referring to FIG. 8, when a user is viewing content using a scroll input while the COEX official app 800 is turned on and a scroll end event occurs due to reaching the end of the scroll range, a dedicated application of the present invention running in the background Information on the COEX official app 800 will be sent to the server 150.

The server 150 sends metadata about the COEX official app 800 in response, and the metadata includes information necessary to configure the switchback UI. The server 150 stores information about applications and services (applications, contents, advertisements, etc.) to be provided through the switchback UI in connection with the information, and then searches for necessary information according to the request of the user terminal and sends it Will give

As shown in (a) of FIG. 8, the switchback UI 850 is dynamically configured and displayed to include
