Context awareness is a technology that provides intelligent services based on users by informing the situation of reality in virtual space in general and presents a technical means for expressing all situations in the real world. Based on this, Which is a human-centered, autonomous service by applying intelligent techniques such as feature extraction, learning, and reasoning. In the context recognition according to the present invention, the device analyzes information exchanged between different users or information transmitted to a device by a user, recognizes the user's desire, determines whether or not an operation related to the recognized content can be performed, Means a technique capable of providing information or function of a result to a user. Through this, the user can control the mobile terminal or the connected external device as well as communicate with the user without knowing the correct command.

5A is a flowchart illustrating an example of a control method using interactive situation recognition according to an embodiment of the present invention.

5A, when a user performs a predetermined menu operation through the user input unit 130 of the mobile terminal 100, or when the control unit 180 automatically selects a connection method such as DLNA or UPnP according to the setting, So that connection with at least one external device can be performed (S510).

Once the data path between the external device and the mobile terminal is established, an interactive user interface according to the present invention may be activated as the user performs a predetermined menu operation or upon establishment of the data path (S520) .

Here, the interactive UI is a UI for inputting a signal to be transmitted to an external device to which a user of the mobile terminal is connected. The interactive UI includes a command / response such as a mobile terminal user and a mobile terminal, Quot; is performed in this text and / or image and thus has been named herein. Hereinafter, it is assumed that the signal received from the user through the interactive UI is in the form of a text. Text is a concept that includes not only simple text but also text accompanied by a tag or a hyperlink.

The interactive UI may have a form of a user interface for a dedicated application operating only when connected to an external device, or may have a form of additional functions of a general instant messenger or an SMS / MMS application.

If the user of the mobile terminal or the user of the connected external device inputs the dialogue through the interactive UI (S530), the context grasp function may be performed (S540). Here, context recognition is a process of analyzing a signal inputted by a user, that is, text, and recognizing the user's desire, and determining whether an operation related to the recognized content can be performed. Here, the subject of the context grasp function may be the control unit 180 of the mobile terminal, the control unit of the external device, or both of the control units may be the subject. For example, when the controller 180 of the mobile terminal merely transmits the conversation input by the user of the mobile terminal to the external device, the control unit of the external device grasps the context, and the control unit 180 of the mobile terminal If it is grasped, a command signal corresponding to the result of the context identification may be transmitted to the external device together with the input dialogue.

If it is determined that there is a function that can be performed by the subject of the context grasp function, the subject can perform a function corresponding to the detected content (S560).

On the contrary, if there is no function that can be performed by the performing entity of the context-grasping result context-aware function, the content may be processed as simple text (S570).

Hereinafter, the context recognition (context recognition) process will be described in more detail with reference to FIG. 5B.

5B is a flowchart illustrating an example of an interactive situation recognition process according to an embodiment of the present invention. In FIG. 5B, it is assumed that the connection protocol with the external device is UPnP.

5B, when a text is inputted through the interactive application UI 581 that can be activated in the UPnP connection, the message parser 582 extracts the input text by element (for example, Word / morpheme, etc.) to judge the meaning of each element. At this time, the message element analyzer can refer to the message database 583 to increase the accuracy of the judgment. The message database includes information on various words / morphemes, may be stored in the memory 160 of the mobile terminal, or may have an external server type that can be connected through the wireless communication unit 110 or the like. When the text segmentation and the semantic determination of the message element analyzer are completed, mapping of the divided elements and the UPnP protocol command in the UPnP function mapper 584 can be performed. For example, if the word "search" is detected in the text, the UPnP feature mapper may map it to the "search" command.

The mapping result is transmitted to each entity 585 that serves as a server and a controller in the UPnP connection, and can be input into the UPnP stack 586 and be put in a waiting state for execution.

The term stack refers to a temporary storage device that temporarily stores data in a storage device in a data structure and allocates a portion of a main memory or a register so that the data can be taken out when necessary.

The above-described message element analyzer 582 and the UPnP function mapper 584 may be implemented in software or as a part of the controller 180 in the form of a hardware module.

Hereinafter, a mode in which various functions are performed through the interactive UI will be described with reference to FIG.

6 is a display state diagram illustrating functions that can be performed through an interactive UI in a mobile terminal according to an exemplary embodiment of the present invention.

In the following embodiments including FIG. 6, it is assumed that the interactive UI is configured in the form of a messenger in which the exchanged messages are sequentially displayed in a thread form. It is also assumed that both the mobile terminal and the external device connected thereto can perform the situation recognition function.

First, referring to FIG. 6A, a list of external devices connectable on the touch screen 151 may be displayed in the form of icons 611, 613, and 615.

At this time, when the user selects the TV icon 615, the control unit 180 can set the TV and data path and activate the interactive UI. If the user desires to issue a command to record a specific broadcast on the connected TV, the user wants to record information about the desired broadcast and the recording intention in the state in which the interactive UI is activated as shown in FIG. 6 (b) . The text may be entered via the user input 130 of the mobile terminal (e.g., a hardware keypad or a virtual keypad displayed on a touch screen, etc.).

The dialog 621 entered by the user is parsed into a plurality of elements through the context recognition process so that the "recording" is mapped to the "SRS createScheduleRecording" command of the UPnP protocol and the "from 11:00 to 12:00 tonight" Is mapped to time information, and "MBC" can be mapped to channel information. At this time, the internal or external message database can be referred to in the parsing process as described above.

When the context recognition function is performed by the controller 180 of the mobile terminal, the controller 180 transmits the createScheduleRecording action command of the UPnP SRS service (or inquiry about the execution of the command) to the connected TV. That is, in this case, only the text entered by the user is displayed on the touch screen 151, and information transmitted to the actually connected TV may be the mapped command and the extracted information. The control unit of the TV can search the EPG or ESG using the command and information received from the mobile terminal, specify the program desired by the user to generate the confirmation information, and transmit the confirmation information to the user's mobile terminal. The control unit 180 of the mobile terminal can convert the confirmation information into the appropriate text 623 and display it as if it was answered on the connected TV. Accordingly, if the user inputs a text 625 indicating affirmation to confirm the recording, the control unit 180 of the mobile terminal maps the text to a recording approval command and delivers the text to the connected TV. Accordingly, the recording operation is scheduled to be completed on the TV.

When performing a situation recognition function on a connected TV rather than on a mobile terminal, the control unit 180 of the mobile terminal may simply transmit 621 and 625 text to the TV, and 623 text may also be received from the TV. Instead, the control unit of the TV may perform the above-described context recognition related functions (e.g., parsing of messages and instruction mapping, etc.).

Meanwhile, the device connected to the mobile terminal can store the access information of the mobile terminal together with the identification information of the mobile terminal, and can provide various functions when the mobile terminal accesses it. For example, if the notebook 611 is selected and connected to the notebook in FIG. 6A, the notebook may provide information on the content provided in the previous connection with the corresponding terminal. The controller 180 of the mobile terminal activates the interactive UI as shown in FIG. 6C and reconstructs the interactive UI by using the text 631 to give an effect as if the notebook invites a conversation and recommends playback. An execution command may be mapped to a portion 632 of the reconstructed text 631. When the user touches the corresponding portion 632 with the pointer 640, the control unit 180 may provide the corresponding content to the connected notebook Can be requested. Accordingly, the corresponding content can be reproduced in the thread form 633 as shown in FIG. 6 (d). Needless to say, the contents can be reproduced in full screen. In addition, when the user inputs a conversation such as "see" through the interactive UI instead of touching the mapped text with the execution command, the corresponding content may be reproduced.

FIG. 6 illustrates a state in which a conversation is performed between a user of the mobile terminal and a device connected to the mobile terminal. According to another aspect of the present embodiment, the user of the connected device can be informed that the mobile terminal is connected, thereby being able to participate in the interactive UI. This will be described with reference to FIG.

7 is a display state diagram illustrating functions that can be performed through an interactive UI in a mobile terminal according to another embodiment of the present invention.

In FIG. 7, it is assumed that the external device connected to the user's mobile terminal is another mobile terminal capable of performing the same function as the above-described mobile terminal. For convenience, the mobile terminal that initiated the connection is referred to as a first terminal, and its user is referred to as a first user, respectively. Also, at least regarding the interactive UI, a terminal that can perform the same function as the first terminal but is connected to the first terminal is referred to as a second terminal, and the user is referred to as a second user.

After the first terminal and the second terminal are connected, the first user activates the interactive UI, and then, on the touch screen 151 'of the second terminal, as shown in FIG. 7 (a) A pop-up window 710 may be displayed. When the second user selects to participate in the dialog in the pop-up window 710, the touch screen 151 of the first terminal displays information 721 informing that the second user participates in the interactive UI, as shown in FIG. 7B, May be displayed. In addition to the form of a pop-up window, the second user may be informed that the interactive UI function is being performed through sound or vibration through the second terminal.

Thereafter, as each user inputs the messages 723 and 725, the interactive UI can perform a function similar to a general instant messenger. However, even when the second user participates in the interactive UI started between the first user and the second terminal, the controller 180 of each terminal can continuously perform the context recognition function for the text input by the corresponding user Of course.

However, in this case, a predetermined visual effect may be given to distinguish the text input by the second user from the response of the second terminal to the command input by the first user. For example, the text 725 input by the second user and the text 731 converted from the response of the second terminal may be set to different colors or patterns of the speech balloon displayed. Alternatively, an icon 733 indicating a response of the second terminal may be displayed when the text 731 converted from the response of the second terminal is displayed. In addition, although not shown, an icon corresponding to the second user, a photograph of the second user, or a thumbnail thereof may be displayed together with the text input by the second user.

According to another aspect of the present embodiment, even when a user between two connected devices uses a general messenger function, the situation recognition function can be executed without a direct command. This will be described with reference to FIG.

8 is a display state diagram illustrating functions that can be performed through an interactive UI in a mobile terminal according to another embodiment of the present invention.

In Fig. 8, a situation similar to Fig. 7 is assumed. However, it is assumed that the situation recognition function is performed by the second terminal of the second user.

8 (a), when a first user and a second user are chatting through a messenger application, a first user sends a conversation 821- > 811- > 823- > 813). Here, the messenger application may be the interactive UI described above, or the interactive UI may be added to the general messenger application in the form of a plug-in or an add-on.

At this time, the control unit of the second terminal maps the word "song" to the multimedia contents in the 811 conversation, recognizes the "Girls' Generation 2" as information for specifying contents in the 823 conversation, It is recognized as a transmission request. As a result, the second terminal can search multimedia content corresponding to the second generation of Girls' Generation through an internal memory, an accessible web page, or a cloud service, and display the result in the form of a conversation 831 on the messenger application. At this time, a predetermined visual effect unit may be provided to the speech balloon to indicate that the message is a message from the second terminal, not the second user, in the dialog 831 output by the second terminal as described above. If it is difficult for the second terminal to directly transmit the content to the first terminal, it may search for and display the URL link in which the content exists, or may display the content itself or the thumbnail thereof.

If the first user inputs an affirmation or a response 815 corresponding to the command in the interactive UI as shown in FIG. 8 (b), the corresponding content transmission from the second terminal to the first terminal can be started. The transmission status can be visually output through the speech bubble 833 on the interactive UI.

On the other hand, this function may interfere with the conversation between users, or may be deactivated to prevent one user from automatically performing an unwanted function (for reasons of privacy, security, etc.). For example, as shown in FIG. 8C, when the second user inputs the dialog 825 of "telephone calming ", the control unit of the second terminal refers to itself as" telephone & It can be recognized as a command to release the function. Accordingly, the control unit of the second terminal may release the status recognition function and notify it on the interactive UI (835). Of course, although not shown, the disabling of the situation recognition function may be performed by touching a specific icon on the interactive UI or by operating a specific button provided on the device.

In FIG. 8, it is assumed that the second terminal performs the context recognition function. However, the first terminal may be configured to perform the context recognition function. For example, when the first user requests specific contents to the second user while monitoring the conversation between the first user and the second user, the controller 180 of the first terminal determines whether the first user And transmit the search request to the second terminal. After obtaining the search result from the second terminal, the first terminal may output the text corresponding to the search result on the interactive UI as if the second terminal responded with the conversation.

In addition, both terminals can recognize the context of each user's conversation, determine the desired operation of each user, and output the functions that the user can perform on the interactive UI in the form of a message.

Meanwhile, according to another embodiment of the present invention, a custom electronic program guide (EPG) function is provided. The EPG function is generally used for a broadcasting station to provide information on a broadcast program to a broadcast receiver in digital broadcasting. The custom EPG function of the present embodiment is a function of setting a content It is a function to provide. In addition to the content scheduling function, various functions such as statistics and editing can be provided through the custom EPG.

9 is a display state diagram illustrating custom EPG setting functions in a mobile terminal according to another embodiment of the present invention.

Referring to FIG. 9A, when the mobile terminal according to the present invention inputs a predetermined command or is connected to another device, it can automatically enter the custom EPG mode. The custom EPG mode refers to a function that allows the mobile terminal to confirm or edit its own EPG when the mobile terminal performs a server role. If the mobile terminal is provided with contents of other connected devices, it can check or edit the EPG of the connected device It can mean a function that can be performed. In FIG. 9, it is assumed that the EPG of the external device connected to the mobile terminal is confirmed / edited. As the user enters the custom EPG mode, the list of EPGs 911 and 913 provided by the corresponding device can be displayed on the touch screen 151. [

Here, if the user selects the October 27 EPG, the functions 921, 923, and 925 that can be performed through the EPG of the corresponding date can be displayed.

If the viewing function 923 is selected here, the details of the corresponding EPG can be browsed as shown in FIG. 9B. If the editing function 925 is selected, the EPG editing mode is entered as shown in FIG. 9C . Here, if the user wishes to add new content and broadcast time, the user can perform scheduling of new content with the selection menu 931. [ Of course, in the editing of the EPG, a predetermined authority of the mobile terminal for the device may be required for security. In addition to the case where editing is performed in the selection menu 931, when broadcasting scheduling is performed through the interactive UI as in the above-described embodiment of the present invention (for example, " EPG can be edited also by using a conversation such as " add a famous broadcast reservation ".

Also, when the statistical function 921 is selected, statistics such as the number of users and the connection time can be displayed during the provision of contents according to the EPG as shown in FIG. 9 (d). Of course, although not shown, other statistics such as device-specific connection statistics, date, day of the week, and time zone classification are also possible.

On the other hand, it is apparent to those skilled in the art that the text-based dialogue in the above embodiments can be replaced with speech recognition.

Further, according to an embodiment of the present invention, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The above-described mobile terminal and its control method are not limited to the configuration and method of the above-described embodiments, but the embodiments may be modified such that all or some of the embodiments are selectively And may be configured in combination.
