Hereinafter, an embodiment of a method for classifying and outputting instant messages sent and received by the portable battery device 100 according to a theme by touch will be described with reference to FIGS. 1, 2, and 4A and 4B do.

The portable electronic device 100 according to the embodiments of the present invention includes a display unit 151 (see FIG. 3) disposed on one surface, for example, a front surface of the portable electronic device 100, .

FIG. 2 is a diagram illustrating a control method for classifying and outputting an instant message transmitted and received by the portable electronic device 100 according to a selected theme according to an embodiment of the present invention. FIG. 4A and FIG. FIG. 2 is a conceptual diagram for explaining a control method of FIG.

Referring to FIG. 2, the portable electronic device 110 outputs an instant message sent and received through the wireless communication unit 110 to the display unit 151 (S200).

The instant message can be transmitted or received through a messenger provided in the portable electronic device 100 according to the present invention or a message related application (ex: Kakao Talk, Next People, WhatsApp) downloaded from the portable electronic device 100. [ In addition, the instant message may be transmitted and received between two talkers, and may be transmitted and received in the form of a group chat by two or more talkers.

4A, the instant messages output to the display unit 151 can be transmitted and received by the plurality of talkers B, C and D (411, 413, 417) and transmitted and received instant messages 412, 414, 416 , 418, and 420 may be composed of various types of data including text, images, moving images, and the like.

In this way, when the instant message is output, the control unit 180 may detect a first touch gesture for a specific instant message, for example, the instant message 416 (S210).

Here, the first touch gesture may be, for example, a touch gesture that long presses the area where the specific instant message 416 is output, but is not limited thereto.

If the first touch gesture is sensed, the controller 180 classifies the instant message 416 into a message of a selected theme according to the second touch gesture (S220).

Here, the second touch gesture is a touch gesture in a manner distinguishable from the first touch gesture. For example, the touch gesture may be touch and drag for an instant message or touch day for a selection menu that pops up according to the first touch gesture. .

4A illustrates an example of selecting the subject when the second touch gesture is a touch for a selection menu popped up according to the first touch gesture.

The control unit 180 can sense a touch on the pop-up selection menu according to the first touch gesture and classify the instant message as a message belonging to the selected topic when a specific topic is selected according to the touch of the selection menu.

Specifically, as shown in FIG. 4A, when a first touch gesture for the instant message 416 is sensed, a selection menu 430 containing one or more selectable objects pops up.

In the selection menu 430, the selectable objects may be, for example, an object displaying a text of 'register as a subject' or 'insert a message in an existing subject'. In addition, subjects previously registered as the sub items of the object in which the text of 'Insert Message on Existing Subject' is displayed, for example, 'overseas travel' and 'A project' may be displayed.

If the user touches the selection menu 430, the controller 180 generates a new topic, and the first touch gesture detects the instant message 416 as a message belonging to a new topic . At this time, the generated subject and related information may be stored in the memory 160 of the portable electronic device 100. [

4A, when the first touch gesture for the instant message 416 is sensed, and a touch to the 'register with subject' object among the objects of the pop-up selection menu 430 is applied, the controller 180 Creates and registers the text 'Let's meet in April' included in the instant message 416 detected as the first touch gesture as a new topic.

On the other hand, if the second touch gesture is a touch on a pop-up menu popped up according to the first touch gesture, and a new instant message is transmitted in a state that a specific topic is selected according to the second touch gesture, Can be classified into messages belonging to the specific topic. In other words, the control unit 180 automatically classifies the instant messages transmitted after a specific topic is selected into messages belonging to the immediately selected topic.

Specifically, if a first touch gesture for the instant message 416 is sensed in FIG. 4A, and a 'foreign travel' item, which is a sub item of the 'insert message to existing subject' object, among the objects of the pop- The controller 180 may switch the current screen of the display unit 151 to a screen displaying instant messages belonging to the topic 'travel abroad'. Then, when a new instant message is transmitted, the control unit 180 directly classifies the instant message into an instant message belonging to the 'travel' topic.

Referring to FIG. 4B, FIG. 4B illustrates an embodiment for selecting the subject when the second touch gesture is touch and drag for an instant message.

The control unit 180 may sense a touch and drag on the instant message 416 and if it is detected that the touch and drag is moved to an area related to a particular subject, Instant messaging.

Specifically, as shown in FIG. 4B, an object 450 may be displayed on the display unit 151 to indicate a specific topic that has been registered and / or selected according to a touch. In FIG. 4B, an object 450 indicating a subject registered in one area (upper area) of the display unit 151, for example, an object 450 displaying a text 'present subject: meet in April' is displayed . Here, the object 450 includes a subject made by at least one of various texts and images.

The control unit 180 may edit at least one of text and images included in the object 450 through a user input. The control unit 180 controls the object 450 to disappear from the display unit 180 and displays the object 450 when a touch is detected in one area (upper area) of the display unit 151. [ Can be controlled.

4B, when the object 450 representing the subject registered in the display unit 151 is displayed, the control unit 180 displays the first touch for the instant message 420 of the image type, for example, Detects a gesture, and detects a touch and drag with the instant message 420 as a touch start point. If the detected touch and drag is detected to be moved to an area related to the subject, for example, an area where the object 450 is displayed, the controller 180 controls the instant message 420 to correspond to the object 450 Classify them into messages belonging to a topic.

Here, the area related to the subject may further include an area in which a message belonging to the specific subject is displayed, in addition to a region in which an object representing a specific subject is displayed on the display unit 151. [

4B, when the controller 180 detects that the touch and drag with the instant message 420 as the touch start point is moved to the area where the subject 450 is displayed, the controller 180 transmits the instant message 420 to the subject 450). In addition, even if it is sensed that the touch and drag with the instant message 420 as the touch start point is moved to the area where another instant message 416 belonging to the topic 450 is displayed, 420) into messages belonging to the subject (450).

If the instant message is classified as such, the controller 180 displays the message belonging to the selected topic visually different from the other instant messages (S230).

Specifically, the control unit 180 may connect the messages belonging to the selected topic to a guide, for example, a tree form, perform the same border processing, highlight processing, display the same color, Changing the size, and so forth.

For example, as shown in FIG. 4B, instant messages 416 and 420 categorized as messages belonging to a topic 450 are linked to each other by tree-shaped guidelines 455 and 465, And are distinguished from other instant messages 412, 414, and 418.

In addition, in another embodiment, when there is a touch (e.g., proximity touch) to an area where instant messages output to the display unit 151 are displayed, the control unit 180 displays a pre- By displaying the selected topic in a view format, it can be distinguished from other instant messages.

As described above, according to the embodiment, the instant messages sent and received are classified according to the selected theme according to the touch, and the messages belonging to the selected topic are distinguished from the other instant messages so that instant messages can be searched, Provide a manageable environment.

Hereinafter, a control method for registering, outputting, editing, and managing an instant message classified according to a topic as described above will be described with reference to FIG. 1, FIG. 3A, and FIGS. 5A and 5B. Since the method of registering a topic has been described above, a description thereof will be omitted here.

In the foregoing, embodiments for sorting, editing, managing, and searching instant messages sent to and received from the portable electronic device 100 according to a theme by touch have been described. The present invention is not limited to the above-described embodiments, but other functions related to the selected topic and other user interfaces therefor can be implemented.

Hereinafter, a control method for classifying instant messages sent to and received from the portable electronic device 100 according to a predetermined reference range will be described with reference to Figs. 1, 3B, 9A to 9C and 10A to 10C .

FIG. 3B is a diagram illustrating a control method for classifying an entire instant message according to a predetermined reference range according to a touch.

Referring to FIG. 3B, the portable electronic device 110 outputs an instant message transmitted and received through the wireless communication unit 110 to the display unit 151 (S400).

In a state where the instant message is output, the controller 180 detects a fourth touch gesture with respect to the display unit 151 (S410).

Here, the fourth touch gesture may be, for example, a touch to a control key displayed in one area of the display unit 151, a flicking in a specific direction applied to one area of the display unit 151, May be a touch input or a drag touch input. However, the present invention is not limited to this, and may include all other types of touch gestures different from the first touch gesture to the third touch gesture.

If the fourth touch gesture is detected, the controller 180 classifies the entire instant message according to a predetermined reference range according to the fourth touch gesture (S420).

Here, the reference range indicates that the instant messages are grouped by a predetermined unit according to the time when instant messages are transmitted and received. For example, the reference ranges may be grouped by date or grouped by week.

The meaning of determining the reference range according to the fourth touch gesture means that the time ranges classified according to the direction and drag length of the touch gesture, for example, are changed. That is, the time range for classifying the instant message can be determined according to the touch.

In another embodiment, the meaning of the reference range according to the fourth touch gesture may mean that the instant message is classified according to a predetermined time range, for example, a fixed weekly time range .

More specific examples will be described in detail below with reference to Figs. 9A to 9C and Figs. 10A to 10C.

9A is a diagram for explaining a control method of classifying a whole instant message according to a predetermined reference range according to an embodiment of the present invention.

The control unit 180 detects the fourth touch gesture with respect to the display unit 151 and displays the current screen of the display unit 151 on a predetermined basis according to the fourth touch gesture, It is possible to switch to a screen displaying at least one image object representing a range.

Here, the fourth touch gesture indicates a gesture in which at least two touch points applied to the display unit 151 are brought close to each other. In addition, the at least two touch points applied to the display unit 151 may be those applied to the background screen, for example, not the area where the instant message is output.

If the distance between the touch points applied to the display unit 151 is relatively wide, the control unit 151 may narrow the predetermined reference range in accordance with the touch by date. In addition, if the distance between the touch points applied to the display unit 151 is relatively narrow, the control unit 180 can set a predetermined reference range broadly in units of weeks. Here, the distance between the touch points applied to the display unit 151 is relatively determined.

In addition, the control unit 180 can flexibly set the reference range based on the touch direction of the fourth touch gesture, the distance between the touch points, the number of times the touch is repeated, and the like. do.

9A, when the instant messages 912, 914, and 916 are output to the display unit 151, a gesture in which at least two touch points applied to the display unit 151 approach each other is detected The controller 180 may classify the instant messages into a range of date units and output the list of image objects 940 indicating the range of each date unit to the display unit 151. [

Text information including year, month, day, and day may be further displayed in the image objects 941 to 946 output to the display unit 151.

In addition, the controller 180 may further display a specific keyword on the output image objects 941 to 946. [ For this, the controller 180 may further include a setting unit 181 for setting at least one search keyword. The control unit 180 may further include a detection unit (not shown) for detecting the set search keyword in the instant messages.

Here, the keyword is an object included in the instant message, and indicates information composed of text that summarizes the instant message. In addition, the fact that a keyword is included in an instant message can be expressed as " information related to an object included in the instant message is tagged ".

A tag is a kind of a set of keywords in which words indicating characteristics, meaning, title, subject, and the like of instant messages are stored in advance. The tag information allows the user to directly input tag information through user input, The tag information may be included in the object itself. In addition, the tag information may be represented by metadata. For example, the metadata is data describing an image object, and is used to efficiently search for the tag or keyword information.

If the search keyword set by the setting unit 181 is included in the instant message of the specific reference range, the controller 180 further displays an indicator indicating the search keyword set on the image object corresponding to the specific reference range can do. At this time, the indicator may be output together with another image (e.g., a thumbnail image) in addition to the text indicating the search keyword.

For example, among the image objects 941 to 946 shown in FIG. 9A, the image object 941 includes a predetermined 'conference' keyword detected in the instant messages sent and received on 'January 10, 2013' And the image object 943 may include a predetermined 'meeting' keyword detected in the instant messages sent and received on 'Saturday, January 12, 2013'.

In this manner, when the current screen of the display unit 151 is switched to the screen displaying the image object according to the fourth touch gesture, if the fifth touch gesture to the display unit 151 is detected, The current screen of the display unit can be switched to the previous screen displaying the instant message.

Here, the fifth touch gesture indicates a gesture in which at least two touch points applied to the display unit 151 are distant from each other. In addition, the at least two touch points applied to the display unit 151 may be those applied to the background screen, for example, not the area where the instant message is output.

The control unit 180 may control the output range of the instant message to vary according to the distance of the touch points applied to the display unit 151 from each other.

For example, if the distance between the touch points applied to the display unit 151 is relatively wide, the controller 151 can narrow the output range of the instant message and output the same. In addition, if the distance between the touch points applied to the display unit 151 is relatively narrow, the control unit 180 can narrow the output range of the instant message and output it. Here, the distance between the touch points applied to the display unit 151 is relatively determined.

9B and 9C illustrate a case where the screen of the display unit 151 is switched to a screen displaying the image objects 941 to 946 according to the fourth touch gesture and a corresponding instant message is displayed according to a touch applied to the image object FIG. 2 is a conceptual diagram for explaining a method of outputting the data. FIG.

In the embodiment of the present invention, when a touch is detected in any one of the output image objects, the controller 151 displays the current screen of the display unit 151 as an instant of a reference range corresponding to the touch- Messages can be switched to the output screen.

For example, if a touch on the image object 941 shown in FIG. 9B is detected, the controller 180 displays instant messages sent and received on 'January 10, 2013' from the first instant message of the day, (151). At this time, if there are many instant messages transmitted and received on the day, the controller 180 may output only some instant messages from the first instant message of the day. In FIG. 9B, the instant message 912 'Good Morning' first transmitted at '9:20 AM' on 'January 10, 2013' is output in chronological order.

In the embodiment of the present invention, when the touch of the indicator displayed on the output image object is detected, the control unit 180 outputs the current screen of the display unit 151 from the instant message including the touch- You can switch to one screen.

For example, when a touch on an indicator indicating the 'conference' search keyword 950a is detected on the image object 941 shown in FIG. 9C, the control unit 180 determines 'Thursday, January 10, 2013' And outputs the first instant message including the 'conference' search keyword among the instant messages transmitted and received to the display unit 151. That is, in FIG. 9C, the instant message 914 received at '3:54 pm on Thursday, January 10, 2013' is output in chronological order from '5:00 meeting'.

10A to 10C are diagrams for explaining a method of classifying an image object representing each reference range according to a narrower reference range according to the number of taps and outputting an instant message related thereto according to an embodiment of the present invention.

10A shows a state where the screen of the display unit 151 is switched to the screen displaying the image objects 1041 to 1046 according to the fourth touch gesture. When the fourth touch gesture is detected again, The range of the reference for classifying the instant message can be set to be wider. In this case, the distance between the touch points applied to the display unit 151 can be relatively determined as described above. That is, the control unit 180 may control the range in which the instant message is outputted according to the degree of proximity of the touch points applied to the display unit 151.

For example, in FIG. 10A, the number of image objects 1041 'to 1043' representing the reference range determined according to the repeated fourth touch gesture is reduced and the range of the classification reference displayed on the image objects is widened. For example, in FIG. 10A, the classification reference range of the image object first output according to the repeated fourth touch gesture is' December 10, 2013 'to' December 31, 2012 to January 6, ', Respectively.

When a touch is detected in any one of the image objects, the controller 180 switches the current screen of the display unit 151 to a screen outputting instant messages of a reference range corresponding to the touch- do.

For example, when a touch on the image object 1042 'shown in FIG. 10B is detected, the control unit 180 transmits instant messages sent and received in' January 7, 2013 to January 13, 2013 ' To the display unit 151 from the first instant message in the range. That is, in FIG. 10B, the instant message 1012 'Good Morning' transmitted at '9:22 am on Jan. 7, 2013' is output in chronological order.

When a touch is detected on any one of the markers displayed on the image object, the controller 180 displays the current screen of the display unit 151 from the instant message including the touch- The instant messaging of the instant messages can be switched to the output screen.

For example, if a touch on the 'conference' indicator 1050'b among the indicators 1050 'displayed in the image object 1042' shown in FIG. 10C is sensed, To the display unit 151 from the first instant message including the 'conference' search keyword among the instant messages transmitted and received between January 7 and January 13, That is, in FIG. 10C, the instant message 1014 received at '3:54 PM' on 'January 10, 2013' is output in chronological order from '5:00 meeting'.

If the instant messages are classified into a predetermined reference range, the controller 180 may convert the current screen of the display unit 151 to a screen displaying at least one image object indicating each of the classified reference ranges. The image object displayed on the display unit 151 may provide a time-based search criterion for searching for a specific instant message desired by the user among past instant messages transmitted and received.

Hereinafter, with reference to FIG. 1, FIG. 2, and FIG. 11A to FIG. 11D, a method of outputting a search window for searching for information related to the instant message in an area distinguished from an area in which an instant message is output, Explains how to search using windows. The embodiments described herein may be implemented independently or with examples that classify instant messages by subject and examples that classify instant messages by touch criteria range.

11A and 11B are diagrams for explaining a control method of outputting a search window for searching for information related to an instant message. FIGS. 11C and 11D illustrate a control method of inputting a search word in the search window FIG.

The control unit 180 may determine the screen orientation of the display unit 151 by sensing the change in tilt of the portable electronic device 100. [

When the screen direction output to the display unit 151 is in the horizontal mode according to the determined screen direction, the controller 180 displays information related to the instant message / instant message in at least one area of the left / right area of the display unit 151 A search window can be displayed for searching.

If the screen direction output to the display unit 151 is the vertical mode according to the determined screen direction, the controller 180 displays information related to the instant message / instant message in at least one area of the upper and lower areas of the display unit 151 A search window can be displayed for searching.

That is, when the screen direction is changed, the area where the search window for searching for information related to the instant message / instant message is also correspondingly changed.

For example, the screen direction shown in Fig. 11A is a portrait mode, and the screen direction shown in Fig. 11B is a landscape mode.

If the flicking or dragging touch inputted to the display unit 151 in a predetermined direction is detected in the state that the screen direction thus output is determined, A search window including a predetermined search word input bar 1173 and a search execution key 1175 can be output to a second area that is different from the first search area. At this time, the first area in which the instant message is output may be at least partially reduced before the touch input is applied.

For example, when the screen direction determined as shown in FIG. 11A is the vertical mode, the controller 151 controls the display unit 151 to display the first direction (upper direction) (E.g., an upper or lower area of the display unit 151) that is different from a first area in which an instant message is output, Can be output.

On the other hand, in another embodiment, the control unit 151 can replace the instant message input window with the search window when the preset criteria are met. Here, the preset reference may be a predetermined type of touch gesture with respect to the display unit 151. In this way, when the instant message input window is replaced with the search window, the 'transfer command' of the 'transfer' key displayed in the existing instant message input window is deactivated and the 'search command' is activated. At this time, the 'key' may display text information ('transmission' or 'search') of the currently activated function. In another example, only one input window is provided, and a plurality of control keys (e.g., a transmission key and a search key) may be provided.

In addition, although only the 'search window' according to the embodiment of the present invention is shown in FIG. 11A, it is needless to say that the instant message input window may be output together.

In addition, the control unit 180 may cause the instant message input window to be output to the first area of the display unit 151 and output the search window to the second area that is distinguished from the first area. Also, the controller 180 may adjust the positions and sizes of the first area and the second area according to a preset reference. Also, the control unit 180 may control the search window to disappear from the display unit 151 normally.

11B, the controller 151 controls the display unit 151 in a second direction (e.g., a left direction or a right direction) applied to one area (e.g., a left / right area) (For example, the left / right area of the display unit 151), which is distinguished from the first area in which the instant message is output, by detecting the flicking or dragging touch input of the instant message The search window can be output.

Also, in another embodiment, the controller 180 may output the search window only when a touch input to a touch gesture other than a flicking or drag touch input, for example, a scroll bar, is detected.

When a touch is detected in the search word input bar 1173 of the search window, the controller 180 may output a touch keyboard for inputting a search word in a lower area of the input bar 1173. [ There are no restrictions on the search terms that can be entered using the touch keyboard. When a predetermined search word (including text, numbers, images, and the like) is input into the search word input bar 1173 of the output search window and a touch is detected by the search execution key 1175, Instant message, and output the search result to the display unit 151. The display unit 151 displays the search result.

In addition, the controller 151 may select a specific sender, a specific search keyword, or the like presented in accordance with a touch input (e.g., a long-press touch input) applied to an area where the search word input bar 1173 is output A menu (not shown) may be popped up. In the state where a selection menu (not shown) is output, for example, when a specific sender is selected, the controller 151 can search for information related to instant messages / instant messages transmitted by the selected specific sender.

Meanwhile, if no search word is input to the output search window for a predetermined time, the control unit 180 may cause the output search window to disappear from the display unit 151.

In the above, a method of outputting a search window for searching for instant messages transmitted and received has been described with reference to FIGS. 11A and 11B. Hereinafter, a control method of inputting a search word into the output search window will be described with reference to FIGS. 11C and 11D.

Referring to FIG. 11C, in a state where a search window is displayed in a second area that is distinguished from the first area in which an instant message is output, the control unit 151 determines whether a drag touch input applied to a specific instant message 1114 is a search word The user can output the specific object included in the instant message 1114 or the instant message 1114, for example, 'conference 5 o'clock' or 'conference' to the search word input bar 1173 have.

If the touch input is applied to the search execution key 1175 in a state where the specific object included in the instant message 1114 or the instant message 1114 is output to the search word input bar 1173, And outputs the search result to the display unit 151. [0064] FIG.

11D, in a state in which a search window is displayed in a second area that is distinguished from the first area in which an instant message is output, the control unit 151 controls the dragging of the instant message 1114 to the sender 1113, When the touch input ends at the search word input bar 1173, the sender 1113 of the instant message 1114 is output to the search word input bar 1173. [

When the touch input is applied to the search execution key 1175 while the sender 1113 of the instant message 1114 is output to the search word input bar 1173, the control unit 180 controls the sender 1114 of the instant message 1114 And outputs the search result to the display unit 151. Here, the information related to the sender 1113 of the instant message 1114 may be, for example, but not limited to, other instant messages sent by the sender 1113.

In addition, the controller 151 may change the size and the output direction of the first area in which the instant message is output and the second area in which the search window is output, an object included therein, a user interface, and the like based on the touch input.

As described above, a search window that can directly search for information related to an instant message can be output in an area distinguished from an area in which instant messages are output according to a touch, so that a user can directly input search criteria of an instant message have.

As described above, according to the portable electronic device and its control method according to the embodiment of the present invention, the instant messages sent and received can be classified according to a selected theme according to a touch, so that a specific instant message and / The related instant messages can be retrieved more easily.

In addition, by switching the screen so that the entire instant message is displayed by a predetermined reference range, for example, a date range, the user can intuitively and quickly search instant messages sent and received on a specific date desired by the user.

Further, a search window is displayed to directly search for information related to an instant message in an area distinguished from an area in which instant messages are output according to a touch, thereby allowing a user to directly input a desired search criterion.
