FIG. 2 is a block diagram illustrating an example of a computer apparatus according to at least one example embodiment. Each of the plurality of electronic devices 110, 120, 130, and 140 or each of the servers 150 and 160 may be implemented by a computer apparatus 200 of FIG. 2.
Referring to FIG. 2, the computer apparatus 200 may include a memory 210, a processor 220, a communication interface 230, and an input/output (I/O) interface 240. The memory 210 may include a permanent mass storage device, such as a random access memory (RAM), a read only memory (ROM), and a disk drive, as a non-transitory computer-readable record medium. The permanent mass storage device, such as ROM and a disk drive, may be included in the computer apparatus 200 as a permanent storage device separate from the memory 210. Also, an OS and at least one program code may be stored in the memory 210. Such software components may be loaded to the memory 210 from another non-transitory computer-readable record medium separate from the memory 210. The other non-transitory computer-readable record medium may include a non-transitory computer-readable record medium, for example, a floppy drive, a disk, a tape, a DVD/CD-ROM drive, a memory card, etc. According to other example embodiments, software components may be loaded to the memory 210 through the communication interface 230, instead of the non-transitory computer-readable record medium. For example, the software components may be loaded to the memory 210 of the computer apparatus 200 based on a computer program installed by files received over the network 170.
The processor 220 may be configured to process instructions of a computer program by performing basic arithmetic operations, logic operations, and I/O operations. The computer-readable instructions may be provided by the memory 210 or the communication interface 230 to the processor 220. For example, the processor 220 may be configured to execute received instructions in response to a program code stored in a storage device, such as the memory 210.
The communication interface 230 may provide a function for communication between the communication apparatus 200 and another apparatus, for example, the aforementioned storage devices. For example, the processor 220 of the computer apparatus 200 may forward a request or an instruction created based on a program code stored in the storage device such as the memory 210, data, and a file, to other apparatuses over the network 170 under control of the communication interface 230. Inversely, a signal, an instruction, data, a file, etc., from another apparatus may be received at the computer apparatus 200 through the communication interface 230 of the computer apparatus 200. For example, a signal, an instruction, data, etc., received through the communication interface 230 may be forwarded to the processor 220 or the memory 210, and a file, etc., may be stored in a storage medium, for example, the permanent storage device, further includable in the computer apparatus 200.
The I/O interface 240 may be a device used for interfacing with an I/O apparatus 250. For example, an input device may include a device, such as a microphone, a keyboard, and/or a mouse, and an output device may include a device, such as a display and/or a speaker. As another example, the I/O interface 240 may be a device for interfacing with an apparatus in which an input function and an output function are integrated into a single function, such as a touchscreen. At least one of the I/O apparatus 250 may be configured as a single apparatus with the computer apparatus 200. For example, a touchscreen, a microphone, a speaker, etc. of a smartphone may be included in the computer apparatus 100.
Also, according to other example embodiments, the computer apparatus 200 may include a greater or smaller number of components than the number of components of FIG. 2. However, there is no need to clearly illustrate most conventional components. For example, the computer apparatus 200 may be configured to include at least a portion of the I/O apparatus 250 or may further include other components, such as a transceiver and a database.
Although a mini-map generally refers to a reduced map of a place in progress in a game, the term “mini-map” used herein may refer to a user interface for reducing and displaying a sequence of contents included in instant messages sent and received through a session corresponding to a chatroom. Here, the sequence of contents may be based on order in which the instant messages are sent and received.
A chatroom including the mini-map may be provided to a user through the computer apparatus 200 of FIG. 2. Here, an application may be installed and run on the computer apparatus 200 as a computer program linked with an instant messaging service, and the computer apparatus 200 may provide the chatroom including the mini-map and the following functions through communication with a server, for example, the server 150, that provides the instant messaging service under control of the application.
FIGS. 3 and 4 illustrate examples of a chatroom including a mini-map according to at least one example embodiment. Here, in the example embodiment of FIGS. 3 and 4, it is assumed that 100 instant messages are sent and received through a session corresponding to a chatroom A 300 and 100 contents ranging from content 1 to content 100 are present in association with the chatroom A 300.
The chatroom A 300 according to the example embodiment of FIGS. 3 and 4 may be implemented to include a first region 310 for displaying a portion of the contents and a second region 320 for displaying a mini-map. For example, in FIG. 3, the first region 310 displays content 31 to content 37 as a portion of the contents of instant messages sent and received through a session corresponding to the chatroom A 300. Also, the second region 320 may display the mini-map that includes content 27 to content 46 as a portion of the contents of the instant messages sent and received through the session corresponding to the chatroom A 300.
Meanwhile, the mini-map displayed on the second region 320 may display all of the contents of the instant messages sent and received through the session corresponding to the chatroom A 300 or may also display only a portion of the contents according to a number of contents as in the example embodiment of FIGS. 3 and 4. Here, the number of contents to be displayed at one time on the mini-map may be determined based on a size of each content, for example, the size of each content according to a length of text, a font size, or a size of an image included in each content. Here, the font size of text or the size of the image may be preset or may be set by a user through a separate setting function. Depending on some example embodiments, the computer apparatus 200 may change and thereby display an image in a form of a thumbnail and may also change and thereby display an image of a person or a place in a form of a specific icon. According to another example embodiment, the computer apparatus 200 may analyze and summarize content and may display the summarized content on the mini-map. According to another example embodiment, the computer apparatus 200 may distinguish contents according to a specific condition and thereby display the contents on the mini-map. For example, the computer apparatus 200 may distinguish contents by person that sends an instant message including corresponding content and thereby display the contents on the mini-map. As another example, the computer apparatus 200 may distinguish contents according to a time or a date at which each corresponding instant message is sent or received and thereby display the contents on the mini-map. As another example, the computer apparatus 200 may display content bookmarked by the user to be distinguished from other contents on the mini-map. To this end, the computer apparatus 200 may provide the user with a user interface for setting a condition for distinguishing contents and may distinguish contents according to the condition set through the user interface and thereby display the contents on the mini-map.
Here, content displayed on the first region 310 may be changed through a user input recognized for the first region 310, and content displayed through the mini-map of the second region 320 may be changed through the user input recognized for the second region 320. For example, contents displayed on the first region 310 or the second region 320 may be changed through a swipe touch gesture in an upward direction or a downward direction recognized for the first region 310 or the second region 320 in a touchscreen environment. Such change of contents may follow a sequence of contents. Referring to FIG. 3, double-headed arrows 330 and 340 may represent that contents to be displayed on the first region 310 and the second region 320 may be changed through the swipe touch gesture in the upward direction or the downward direction recognized for the first region 310 and the second region 320, respectively.
Also, referring to FIGS. 3 and 4, a first indicator 350 indicates contents on the mini-map corresponding to the contents displayed on the first region 310. When the contents displayed on the first region 310 are changed, the contents indicated on the mini-map by the first indicator 350 may be changed to correspond to the contents displayed on the first region 310. For example, when contents ranging from content 31 to content 37 displayed on the first region 310 of FIG. 3 are changed to contents ranging from content 50 to content 56 displayed on the first region 310 of FIG. 4 in response to a user input for the first region 310, contents displayed on the mini-map of the second region 320 may be changed from the contents ranging from content 31 to content 37 indicated on the second region 320 of FIG. 3 by the first indicator 350 to the contents ranging from content 50 to content 56 indicated on the second region 320 of FIG. 4 by the first indicator 350. Conversely, contents displayed on the second region 320 may be changed in response to a user input for the first indicator 350, for example, a touch-and-drag touch gesture in an upward direction or a downward direction relative to the first indictor 350 in a touchscreen environment. In this case, the contents indicated by the first indicator 350 may be changed and accordingly, contents to be displayed on the first region 310 may be changed to the contents indicated by the first indicator 350. As another example, when the user selects one of contents displayed on the mini-map of the second region 320, a portion of a sequence of contents including the selected content may be displayed on the first region 310. Even in this case, according to a sequence of contents displayed on the first region 310, contents to be displayed on the second region 320 and the first indicator 350 may be changed. That is, the contents to be displayed on the first region 310 and the contents indicated by the first indicator 350 may be dynamically changed to correspond to each other, and the contents to be displayed on the mini-map of the second region 320 may be dynamically changed based on the contents indicated by the first indicator 350.
Also, the second region 320 may include a bar 360 representing the entire sequence of contents of the chatroom A 300 and a second indicator 370 indicating a position on the bar 360 of the contents displayed on the first region 310. The user may search for contents by moving the second indicator 370, for example, by moving the second indicator 370 through a touch-and-drag touch gesture in an upward direction or a downward direction relative to the first indicator 350 in a touchscreen environment. Here, according to the movement of the second indicator 370, all of the contents displayed on the mini-map of the second region 320, the contents indicated by the first indicator 350, and the contents displayed on the first region 310 may be changed.
FIGS. 5 and 6 illustrate examples of a bookmark according to at least one example embodiment. FIG. 5 illustrates an example in which a bookmark 510 is set to content 52 among contents displayed on the first region 310 of the chatroom A 300. In this case, a bookmark 520 may be automatically set to content 52 on the mini-map of the second region 320 to correspond to the bookmark 510. Here, referring to FIG. 6, although contents displayed on the first region 310 is changed to content 58 to content 64 and content 52 is not displayed on the first region 310, the bookmark 520 is set to the content 52 displayed on the mini-map of the second region 320. In this case, the user may quickly search the entire contents for bookmarked contents through the mini-map of the second region 320.
FIGS. 7 and 8 illustrate examples of distinguishing contents according to a set condition and thereby displaying the contents on a mini-map according to at least one example embodiment.
FIG. 7 illustrates an example in which the computer apparatus 200 displays contents (content 28, content 31, content 34, and content 45 in the example embodiment of FIG. 7) of instant messages sent from a user “A” to be distinguished from contents of instant messages sent from other users. In the example embodiment of FIG. 7, the computer apparatus 200 displays the contents of the instant messages sent from the user “A” using a color. However, it is provided as an example only. Content according to a specific condition may be displayed to be distinguished from other contents based on a size, a shape, etc., of the displayed content.
FIG. 8 illustrates an example in which the computer apparatus 200 distinguishes and thereby displays contents by date. In the example embodiment of FIG. 8, it is possible to easily verify that a date in which instant messages corresponding to content 42 to content 44 are sent, a date in which instant messages corresponding to content 45 to 57 are sent, and a date in which instant messages corresponding to content 58 and content 59 are sent are different from each other. Also, users may easily and quickly navigate contents of a desired date by indicating a corresponding date in which instant messages corresponding to the distinguished contents are sent using a first box 810 and a second box 820 each indicated with dotted lines in FIG. 8.
Although an example of distinguishing and thereby displaying contents according to a user or a date is described with reference to FIGS. 7 and 8, a content format may be used as a condition for distinguishing and thereby displaying contents depending on some example embodiments. Here, the content format may include, for example, a text, an image, a link, an emoticon, and a sticker. As another example embodiment, a user query may be used as the condition. For example, when the user inputs a text through a search interface of the chatroom A 300 or when a portion of texts displayed through the chatroom A 300 is selected, the computer apparatus 200 may distinguishably display content including the input or selected text on the mini-map of the second region 320.
Also, a condition of distinguishing and thereby displaying contents may be used as a condition of filtering contents.
FIG. 9 illustrates an example of filtering contents according to a set condition and thereby displaying the filtered contents on a mini-map according to at least one example embodiment. FIG. 9 illustrates an example in which the computer apparatus 200 filters and thereby displays contents according to a content format. For example, in FIG. 9, contents in an image format may be filtered and thereby displayed through the mini-map of the second region 320. In this case, the user may quickly access content in the image format among contents included in instant messages sent and received in association with the chatroom A 300. For example, when the user selects content 95 from among the contents filtered and thereby displayed on the mini-map of the second region 320 of FIG. 9, a sequence of contents including content 95 may be displayed through the first region 310.
Meanwhile, although an example of filtering contents according to a content format is described with reference to FIG. 9, a date or a time, user information of a user that sends a message, and the like may be used as a content filtering condition.
FIG. 10 illustrates an example of a user interface for setting a condition according to at least one example embodiment. A user interface 1000 of FIG. 10 represents an example of a setting screen for the chatroom A 300. The setting screen may be provided for each chatroom and/or may be collectively provided for all chatrooms.
A first box 1010 indicated with dotted lines represents an example of a selection button that allows the user to select whether to use a mini-map. If the mini-map is set to be used, the mini-map may be displayed as described above with reference to FIGS. 3 to 9. If the mini-map is set to not be used, the mini-map may not be displayed.
A second box 1020 indicated with dotted lines represents an example of a selection button for setting whether to use a function of distinguishing (or alternatively, discriminating or filtering) displaying content to be displayed.
Here, a third box 1030 indicated with dotted lines includes a selection button 1031 for selecting whether to distinguishably display content by user and a selection function 1032 for selecting a specific participant from among participants of the chatroom A 300. For example, the computer apparatus 200 may distinguishably display contents of selected participants of the chatroom A 300 on the mini-map according to a setting of the selection button 1031, and in response to a selection on a specific participant through the selection button 1032, the computer apparatus 200 may distinguishably display only content included in an instant message of the selected specific participant. Depending on some example embodiments, the computer apparatus 200 may display contents of the selected participants of the chatroom A 300 on the mini-map to be visually distinguishable, for example, using a color or a shape, for each participant according to a setting of the selection button 1031.
Also, a fourth box 1040 indicated with dotted lines includes a selection button 1041 for selecting whether to distinguishably display content by date and an input function 1042 for receiving an input of a specific date. For example, the computer apparatus 200 may distinguishably display contents of the mini-map by date according to a setting of the selection button 1041, and in response to a selection on a specific date (or, a date range, a specific time, and a time range) through the input function 1042, the computer apparatus 200 may distinguishably display only content included in instant messages sent and received on the selected date (or the date range, the specific time, and the time range). Depending on some example embodiments, the input function 1042 may provide an interface for selecting date (or the date range, the specific time, and the time range) in a form of a calendar.
A fifth box 1050 indicated with dotted lines includes a selection button 1051 for selecting whether to distinguishably display content according to a content format and a selection function 1052 for receiving a selection of a specific content format. For example, the computer apparatus 200 may display contents of the mini-map to be distinguished for each desired (or alternatively, predesignated) content format according to a setting of the selection button 1051 and may also distinguishably display only content in a specific content format selected through the selection function 1052.
A sixth box 1060 indicated with dotted lines represents an example of a selection button capable of setting whether to use a filtering function of filtering and thereby displaying contents. If the filtering function is set to be used, functions for setting a filtering condition similar to the third box 1030 to the fifth box 1050 each indicated with dotted lines may be provided.
A seventh box 1070 indicated with dotted lines represents an example of a selection button capable of selecting whether to use a content summarization function. In the case of using the content summarization function, the computer apparatus 200 may analyze and summarize content of an instant message directly or in association with a server that provides an instance messaging service and may display the summarized content through the mini-map.
Meanwhile, a display status may be automatically set to the mini-map based on a screen size of a user device, for example, the computer apparatus 200 or a size of a display region on which an instant message application is displayed within an application within a screen of the user device. For example, when a screen size or a size of the display region of the user device is less than or equal to a first threshold, the mini-map may not be displayed although the user is set a condition to use the mini-map. Similar thereto, a default value for a size of content displayed through the mini-map may be set based on the screen size of the user device. Also, content displayed on the mini-map according to the screen size of the user device may be modified. For example, when the screen size of the user device is less than or equal to a second threshold, content may be automatically filtered or modified and thereby displayed on the mini-map. For example, only bookmarked content, only contents of instant messages sent and received within a desired (or, alternatively, predetermined) time range, or summarized content may be displayed on the mini-map.
Also, a size of a second region on which the mini-map is displayed may be adjusted according to the screen size of the user device.
Also, depending on some example embodiments, the mini-map may be provided as a separate mini-map screen according to the screen size of the user device. For example, when the screen size of the user device is less than or equal to a third threshold, the chatroom A 300 may be provided as a separate mini-map screen by switching to a mini-map mode. Here, when the user selects specific content from among contents displayed on the mini-map screen, the mini-map screen may be switched again to the screen of the chatroom A 300 and a portion of a sequence of contents including the selected specific content may be displayed on the screen of the chatroom A 300.
FIG. 11 is a flowchart illustrating an example of a mini-map providing method according to at least one example embodiment. The mini-map providing method may be performed by the computer apparatus 200. Here, the processor 220 of the computer apparatus 200 may be implemented to execute a control instruction according to a code of at least one computer program or a code of an OS included in the memory 210. Here, the processor 220 may control the computer apparatus 200 to perform operations 1110 to 1160 included in the method of FIG. 11 in response to the control instruction provided from the code stored in the computer apparatus 200.
In operation 1110, the computer apparatus 200 may display a first portion in a sequence of contents included in instant messages sent and received through a session corresponding to a chatroom on a message display region on a screen for displaying the chatroom. Here, the message display region may correspond to the first region 310 described above with reference to FIGS. 3 to 9. Although description is made based on an example of displaying contents in a form of a speech balloon with reference to FIGS. 3 to 9, a content display format is not limited to a speech balloon. The first portion displayed when a user enters the chatroom may include an end portion of the sequence of contents.
In operation 1120, the computer apparatus 200 may display a second portion that includes the first portion in the sequence of contents on a mini-map display region on the screen for displaying the chatroom. Here, for example, a size of each content included in a subsequence of the second portion may be set to be less than a size of each content included in a subsequence of the first portion. Here, the size of each content may include at least one of a length of text included in the content, a font size of text included in the content, and a size of an image included in the content. As another example, a number of contents included in a first subsequence of the second portion may be greater than a number of contents included in a second subsequence of the first portion. The mini-map is to navigate contents of instant messages sent and received through a session corresponding to the chatroom and a number of contents displayed on the mini-map display region may be set to be greater than the number of contents displayed on the message display region, but a size of each content displayed on the mini-map display area may be set to be smaller than a size of each content displayed on the message display region. The number or the size of contents may be directly set by the user or may be automatically set according to a size of a display on which the screen is displayed.
For example, in operation 1120, the computer apparatus 200 may modify the contents included in the subsequence of the second portion. Here, modification of contents may be performed according to a setting of the user or the size of the display. As an example of modifying the contents, the computer apparatus 200 may reduce at least one of a font size and an image size of contents included in the subsequence of the second portion. As another example, the computer apparatus 200 may replace an image with an icon or may summarize a text and replace the text with the summarized text, in the contents included in the subsequence of the second portion. As another example, the computer apparatus 200 may replace the contents included in the subsequence of the second portion with bookmarked contents or a sequence of times at which instant messages corresponding to the contents are sent and received.
In operation 1130, the computer apparatus 200 may interact with the message display region and the mini-map display region. For this interaction, operation 1130 may include operations 1131 and 1132.
In operation 1131, when the first portion displayed on the message display region is changed, the computer apparatus 200 may change the second portion changed to include the changed first portion to be displayed on the mini-map display region. For example, in response to a change from a first subsequence (e.g., content 31 to content 37) of contents displayed on the first region 310 corresponding to the message display region to a second subsequence (e.g., content 50 to content 56), changing a third subsequence (e.g., content 27 to content 46) of contents displayed on the second region 320 corresponding to the mini-map display region to a fourth subsequence (e.g., content 41 to content 60) is described above with reference to FIGS. 3 and 4. Here, that the changed fourth subsequence includes the changed second subsequence may be verified.
In operation 1132, when content or a subsequence of contents is selected from the second portion displayed on the mini-map display region, the computer apparatus 200 may change the first portion displayed on the message display region to include the selected content or subsequence of contents in the first portion. Also, as described above with reference to FIGS. 3 and 4, when the contents displayed on the second region 320 are changed in response to a user input for the first indicator 350, the contents indicated by the first indicator 350 may be changed and accordingly, contents to be displayed on the first region 310 may be changed to the contents indicated by the first indicator 350. Also, as described above with reference to FIGS. 3 and 4, when the user selects one of the contents displayed on the mini-map of the second region 320, a portion of a sequence of contents including the selected content may be displayed on the first region 310.
Meanwhile, the computer apparatus 200 may set a condition for at least one of a sending time range of an instant message, a sender of the instant message, and a content format. Here, the computer apparatus 200 may distinguish contents included in the subsequence of the second portion according to the set condition and thereby display the contents on the mini-map display region. For example, an example of distinguishably displaying content of an instant message sent from a specific sender is described with reference to FIG. 7 and an example of distinguishably displaying contents by date on which a corresponding instant message is sent is described with reference to FIG. 8.
Also, the computer apparatus 200 may set a condition for at least one of a sending time range of an instant message, a sender of the instant message, and a content format. Here, the computer apparatus 200 may filter contents included in the subsequence of the second portion according to the set condition and thereby display the contents on the mini-map display region. For example, an example of filtering contents that include an image and thereby displaying the filtered contents on the mini-map display region is described with reference to FIG. 9.
To this end, the computer apparatus 200 may provide a user interface for setting a condition and may register the condition selected or input through the user interface as a setting value. Here, a condition for distinguishing contents and a condition for filtering contents may be individually set. An example of the user interface 1000 for setting the condition is described above with reference to FIG. 10.
In operation 1140, the computer apparatus 200 may provide a bookmark setting function for contents included in a subsequence of the first portion. For example, in response to a selection from the user on each of contents displayed on the message display region, the computer apparatus 200 may provide a function for bookmarking the selected content to the user.
In operation 1150, when a bookmark is set to first content among the contents included in the subsequence of the first portion through the bookmark setting function, the computer apparatus 200 may display the set bookmark through the first content included in the subsequence of the second portion. That is, a bookmark of specific content set in the message display region may be displayed in association with the specific content on the mini-map display region when displaying the specific content on the mini-map display region. When corresponding content is not displayed on the message display region and is displayed on the mini-map display region, the bookmark may be displayed in association with the corresponding content on the mini-map display region.
In operation 1160, when a size of a display on which the screen is displayed is less than or equal to a first threshold or when a size of each content included in the subsequence of the second portion is less than or equal to a second threshold, the computer apparatus 200 may switch the screen to a mini-map mode screen. Here, the contents included in the subsequence of the second portion may be displayed on the mini-map mode screen. That is, when the size of the display is too small, for example, less than or equal to the first threshold value, or when the size of contents of the mini-map is too small for the user to recognize, the computer apparatus 200 may switch the screen to the mini-map mode screen such that the mini-map may be displayed on the screen without displaying a screen for the chatroom.
When the user enters the chatroom, the computer apparatus 200 may initially display the mini-map mode screen on which the contents included in the subsequence of the second portion are displayed. Here, when a desired (or alternatively, preset) period of time elapses or when at least one of the contents displayed on the mini-map mode screen is selected by the user, the computer apparatus 200 may display the screen on which a selected content is displayed and including the message display region and the mini-map display region. That is, the computer apparatus 200 may initially display the mini-map mode screen to facilitate navigating of the user and, when the desired (or alternatively, preset) period of time is elapses or when the user selects specific content, may display the screen on which the selected content is displayed and including the message display region and the mini-map display region.
According to some example embodiments, it is possible to provide a mini-map for contents of instant messages sent and received through a session corresponding to a chatroom.
By providing a mini-map for content of instant messages, the methods and/or systems according to some example embodiments enable a user to quickly locate and ascertain contents of his/her interest in the message display region, reducing a user's scrolling effort or filtering effort through the plurality of instant messages exchanged in the chatroom. Accordingly, computing/processing resources of a computer apparatus may be used less, thereby reducing power consumption associated therewith.
