The electronic device 10 includes a communication unit 100, an operation reception unit 102, a data holding unit 110, and a posting site browsing control unit 120. In terms of hardware components, these configurations are realized by a CPU or GPU of an arbitrary computer, a memory, a program loaded in the memory, and the like, but here, functional blocks realized by their cooperation are drawn. . Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  For example, the posting site browsing application may include program modules corresponding to the operation receiving unit 102, the data holding unit 110, and the posting site browsing control unit 120 in FIG. The functions of the blocks of the operation accepting unit 102 and the posting site browsing control unit 120 are stored in the storage 66 and program modules corresponding to the blocks are appropriately read to the main memory 64 and executed by the CPU 60 and the GPU 62. May be realized. Further, the function of each functional block of the data holding unit 110 may be realized by holding data in the main memory 64 or the storage 66.

  The communication unit 100 is realized by the wireless communication module 71 and the mobile phone module 72, and performs data communication between the posting site browsing control unit 120 and the server 5 by executing communication processing with the server 5 via the network 3. Intermediary between sending and receiving. For example, the communication unit 100 may perform HTTP communication with the server 5 in response to a request from the posting site browsing control unit 120.

  The operation accepting unit 102 accepts an operation input by a user input from the operation unit 70, the front touch pad 21, and the rear touch pad 32. This operation can be said to be an operation for executing the function of the posting site browsing application, and can also be said to be a browsing operation for the posting site. In the following, it is assumed that the user inputs an operation for the posting site browsing application by operating the front touchpad 21 with a finger.

  The operation reception unit 102 detects a “touch operation” when the user's finger touches the front touch pad 21, and detects a “release operation” when the user's finger leaves the front touch pad 21. In particular, when the interval between the touch operation and the release operation is less than a predetermined time (for example, less than 500 milliseconds), typically, when the user performs an operation of tapping the front touchpad 21, it is detected as a “tap operation”. And Further, after detecting a touch operation, if a release operation is not detected for a predetermined time or longer (for example, 500 milliseconds or longer), it is detected as a “long press operation”.

  Further, the operation receiving unit 102 detects an operation of tracing the front touch pad 21 without releasing a finger after the user touches the front touch pad 21 as a “slide operation”. The slide operation is sometimes called “trace operation” or “drag operation”. Further, a short slide operation such as lightly touching the front touch pad 21 is detected as a “flick operation”. The operation receiving unit 102 also acquires coordinates indicating positions where various operations have been performed on the front touchpad 21 from the front touchpad 21. The operation reception unit 102 identifies an operation position, for example, an object (for example, a tab) on the screen that is an operation target, in addition to the user's operation content on the front touchpad 21.

  The data holding unit 110 is a storage area for various data. The data holding unit 110 includes a sorting reference table 112 and a history table 114. The distribution criteria table 112 is the user's operation content for the posting site browsing application, and holds data serving as a reference for distributing the execution content of the function provided by the posting site browsing app to the tab of the posting site browsing app. In other words, the correspondence relationship between the operation content and the tab for specifying the tab to be associated when the information indicating the operation content of the user is stored as the execution history is held.

  FIG. 6 schematically shows data stored in the sorting reference table 112. For example, it is an operation to browse a “timeline” that lists a plurality of comments posted by other users in chronological order, and the execution of the user timeline browsing function in the posting site browsing application is associated with the home tab . In addition, the comment includes a specific user name, and is an operation for browsing a comment (hereinafter referred to as “related comment”) associated with the specific user on the posting site. The execution of the function is associated with the related tab. Also, this is an operation for sending a message addressed to a specific user (hereinafter referred to as “individual message”), and the execution of the individual message transmission function in the posting site browsing application is associated with the individual message tab. .

  Returning to FIG. 5, the history table 114 holds an execution history of each function of the posting site browsing application. Specifically, an execution history indicating the past performance of the user by executing the function of the posting site browsing application is held in association with each tab provided by the posting site browsing application. This execution history can be said to be the operation history in browsing of the posting site performed by the user via the posting site browsing application, and the identification information of the content displayed in the past in browsing of the posting site is displayed for each function of the posting site browsing application. It can be said that it was classified into.

  For example, in the history table 114 of the home tab, the name of the user who browsed the timeline by the user of the electronic device 10 is stored in association with the viewing date and time. Also, in the related tab history table 114, the name of the user who browsed the related comment by the user of the electronic device 10 is stored in association with the browsing date and time. In the history table 114 of the list tab, the name of a list (here, a list showing a list of grouped users) that the user of the electronic device 10 browsed is stored in association with the browsing date.

  In the individual message tab history table 114, the name of the user who transmitted the individual message by the user of the electronic device 10 is stored in association with the transmission date and time of the individual message. In the history table 114 of the favorite tab, comments registered as favorites by the user of the electronic device 10 are stored in association with the registration date and time. In the history table 114 of the hash tag search tab, hash tags searched by the user of the electronic device 10 are stored in association with the search date. In the history table 114 of the character string search tab, an arbitrary character string searched by the user of the electronic device 10 is stored in association with the search date.

  The posting site browsing control unit 120 includes a posting site access unit 122, an operation determination unit 124, a history recording unit 126, and a display control unit 130. The posting site access unit 122 accesses the server 5 in response to a user operation received by the operation receiving unit 102, and transmits various data related to comments to the server 5 by calling an API published by the posting site. Also, various electronic contents related to comments are acquired from the server 5.

  For example, the posting site access unit 122 uploads comments and profile information input by the user to the server 5 and registers favorite comments in response to a browsing operation of the posting site by the user. In addition, a search request specifying a hash tag or an arbitrary character string or a timeline acquisition request is transmitted to the server 5. In addition, the server 5 acquires the search result by the timeline data of itself or other users, the data of the timeline in a certain list, the hash tag or an arbitrary character string. Of course, the display data in the electronic device 10 may be extracted by parsing the acquired data.

  FIG. 7 schematically shows the connection of electronic contents held at the posting site. In the posting site according to the present embodiment, a plurality of users are associated with each other because a certain user registers another user as a friend and / or a certain user registers as a friend with another user. For example, when the first user registers the second user as a friend, the posted comment of the second user is reflected in the timeline of the first user. Conversely, when the first user is registered as a friend with the second user, the posted comment of the first user is reflected in the timeline of the second user.

  As shown in FIG. 7, the user “taro” of the electronic device 10 can sequentially browse the content related to each user across a plurality of users, starting from his own timeline. In addition, it is possible to sequentially browse a plurality of types of content corresponding to a plurality of functions of the posting site browsing application. In FIG. 7, the content that is displayed as history is displayed as the content, in other words, the content whose execution history is recorded in association with each tab of the posting site browsing application is shown as the specific content 140. .

  Returning to FIG. 5, the operation determination unit 124 is a user operation received by the operation receiving unit 102, in other words, a browsing site browsing application to which an execution history indicating the operation content is associated with a browsing operation on the posting site. Identify the tab. Specifically, with reference to the distribution criteria table 112, it is determined which of the plurality of tabs corresponds to the execution content of the posting site browsing application according to the user's operation, or does not correspond to any of them.

  The history recording unit 126 records the execution history in the tab history table 114 corresponding to the user operation specified by the operation determination unit 124 in association with the execution date and time of the function of the posting site browsing application. This execution date and time may be the system time when the operation receiving unit 102 receives an operation input, or may be the system time when the function of the posting site browsing application is executed in response to the operation input. The system time when the table 114 is updated may be used.

  A specific example of execution history recording by the operation determination unit 124 and the history recording unit 126 will be described. For example, when the user of the electronic device 10 performs an operation for displaying the timeline of another user who is registered as a friend, the user name of the other user is recorded in the history table 114 of the home tab as an execution history. Further, when the user of the electronic device 10 performs an operation of displaying a related comment of another user, the user name of the other user is recorded in the history table 114 of the related tab as an execution history. When the user of the electronic device 10 performs an operation for displaying a list timeline, the list name is recorded in the history table 114 of the list tab as an execution history.

  When the user of the electronic device 10 performs an operation of transmitting an individual message to another user, the user name of the other user is recorded as an execution history in the history table 114 of the individual message tab. When the user of the electronic device 10 performs an operation for registering a comment as a favorite, the content of the comment is recorded in the favorite tab history table 114 as an execution history. When the user of the electronic device 10 performs a search operation specifying a hash tag, the hash tag is recorded in the history table 114 of the hash tag search tab as an execution history. Similarly, when searching with an arbitrary character string other than the hash tag, the character string is recorded in the history table 114 of the character string search tab as an execution history.

  The display control unit 130 causes the display device 20 to display electronic data such as an image corresponding to a user operation received by the operation receiving unit 102.

When the character string search tab 212g is tapped, an input form for an arbitrary character string and a list of character strings with a high search frequency on the posting site are displayed.

  As shown in FIG. 9, when a touch operation on any of the function tabs 212 is detected, the tab display control unit 134 displays an image (hereinafter, referred to as “sliding operation” on the function tab 212 to be operated). , “Guide 214”) is displayed in association with the function tab 212 to be operated. Further, the guide 214 is continuously displayed during the period in which the touch operation is continued. The guide 214 can be said to be a hint for showing the direction of the slide operation to the user, and is also referred to as “affordance”. FIG. 9 shows a state in which a touch operation on the individual message tab 212d is detected and a guide 214 imitating a slide switch is displayed in association with the individual message tab 212d.

  As described above, in the electronic device 10, even when a tap operation as a normal operation is performed on the function tab 212, the guide 214 is displayed to indicate to the user that there is a slide operation on the function tab 212. Note that the guide 214 may be displayed in response to an operation different from the normal operation such as a long press operation, but in this case, the user needs to perform an operation different from the normal operation. As a result, the guide 214 may not be displayed, in other words, the user may not notice the presence of the slide operation. In the electronic device 10 according to the embodiment, the guide 214 is displayed by a touch operation that is inevitably performed in the tap operation as a normal operation, so that the user's awareness of the slide operation can be promoted.

  As a modification, the tab display control unit 134 may display the guide 214 together with an object that suggests the direction of the slide operation. Specifically, while the guide 214 is being displayed, various objects such as the function tab 212 and a predetermined mark may be slid in the direction in which the slide operation should be performed in the vicinity of the guide 214. For example, the individual message tab 212d and other marks may be slid from left to right in the guide 214 of FIG. This makes it easy for the user to notice that a slide operation on the function tab 212 is possible in the slide display direction of the object. Further, the tab display control unit 134 may display a message indicating that history display is performed in association with the guide 214. For example, the character string “history display” may be displayed in or near the guide 214. Accordingly, it becomes easy for the user to notice that the history is displayed by the slide operation on the function tab 212.

  As shown in FIG. 10, the user performs a slide operation to the right with respect to the function tab 212 according to the guide 214 displayed by the touch operation, whereby the history screen 216 is displayed on the display device 20 in full screen. . Specifically, when a slide operation to the right with respect to the function tab 212 is detected, the history display control unit 136 displays the history screen 216 in a translucent manner over the entire posting site browsing screen. For example, the history screen 216 may be displayed with a predetermined transparency with which the user can view the contents of the content screen 204 by a known image processing technique such as α blend. In FIG. 10, the translucent history screen 216 is schematically shown by hatching.

  Further, the history display control unit 136 refers to the history table 114 of the function tab 212 in which the slide operation is detected, and displays the execution history 218 stored in the table on the history screen 216. Specifically, execution histories are displayed side by side in descending order of execution date and time, in other words, new execution histories are displayed on the left side of the history screen 216. Further, the history display control unit 136 displays the new execution history in order, in other words, first displays the latest execution history, and then sequentially displays the old execution history sequentially.

  If the number of execution histories held in the history table 114 is large and does not fit within the history screen 216, the old execution history may be hidden. In this case, in response to the user's left flick operation on the history screen 216, the relatively new execution history that has been displayed so far is shifted to the left to be sequentially hidden, and the relatively old that has been hidden until then is displayed. The execution history may be displayed sequentially.

  In the history screen 216, a region near each execution history 218 is set as a region for accepting a user's selection operation for the execution history 218. The operation reception unit 102 detects a tap operation in the area as a tap operation for the execution history 218. When a tap operation on the execution history 218 is detected on the history screen 216, the history display control unit 136 ends the display of the history screen 216. The main display control unit 132 displays an execution result of the posting site browsing application indicated by the tapped execution history 218 and displays the content of the posting site indicated by the execution history 218 on the content screen 204.

  Specifically, the posting site access unit 122 may transmit a content acquisition request corresponding to the tapped execution history to the server 5 and acquire the content corresponding to the tapped execution history from the server 5. For example, when the execution history indicates that a specific user's timeline is displayed, an acquisition request for the user's timeline may be transmitted to the server 5. If the execution history indicates that a search result by a specific keyword is displayed, a search request specifying the keyword may be transmitted to the server 5.

  As described above, the posting site access unit 122 may acquire the electronic content of the posting site indicated by the tapped execution history from the server 5 as the execution result of the posting site browsing application indicated by the tapped execution history. The main display control unit 132 causes the content screen 204 to display the electronic content acquired by the posting site access unit 122 when the execution history is selected by the user.

A specific example of the display of the execution history and the display of the result of the user selecting the execution history will be described.
The history display control unit 136 displays, as the home tab execution history, the names of other users who have browsed past timelines by the user of the electronic device 10. When a specific user name is tapped, the main display control unit 132 displays the timeline of the other selected user on the content screen 204.

  In addition, the history display control unit 136 displays the name of the user who browsed past related comments by the user of the electronic device 10 as the execution history of the related tab. When a specific user name is tapped, the main display control unit 132 displays the related comment of the selected user on the content screen 204.

  In addition, the history display control unit 136 displays the list name that the user of the electronic device 10 browses the past timeline as the execution history of the list tab. When a specific list name is tapped, the main display control unit 132 causes the content screen 204 to display a timeline of the selected list.

  Further, the history display control unit 136 displays the user name of the destination to which the user of the electronic device 10 has transmitted the past individual message as the execution history of the individual message tab. When a specific user name is tapped, the main display control unit 132 displays an individual message destined for the selected user on the content screen 204.

  Further, the history display control unit 136 displays a comment character string registered as a favorite in the past by the user of the electronic device 10 as an execution history of the favorite tab. When a specific comment character string is tapped, the main display control unit 132 causes the content screen 204 to display the selected comment character string.

  Further, the history display control unit 136 displays the hash tag searched in the past by the user of the electronic device 10 as the execution history of the hash tag search tab. When a specific hash tag is tapped, the main display control unit 132 displays the search result of the posting site by the selected hash tag on the content screen 204.

  Further, the history display control unit 136 displays a character string (search word) searched in the past by the user of the electronic device 10 as the execution history of the character string search tab. When a specific search word is tapped, the main display control unit 132 displays the search result of the posting site by the selected search word on the content screen 204.

  The history display control unit 136 also hides the history screen 216 when a user's selection operation is detected on a portion other than the area where the selection of the execution history 218 is received on the history screen 216. In this case, the display content of the content screen 204 is not updated and is maintained as it is. For example, in FIG. 10, when a portion other than the area where the character string as the execution history 218 is displayed on the history screen 216, for example, a portion above or below the execution history 218, the history screen 216 and the execution history 218 are displayed. End the display. Thereby, it is not necessary to provide a button for ending the display of the history screen 216, and the entire screen of the display device 20 can be used for displaying the execution history.

  FIG. 10 shows a state in which the individual message tab 212d has been slid and the individual message tab execution history 218 is displayed, and FIG. 11 shows that the related tab 212b has been slid and the related tab execution history 218 is displayed. It shows the state that was done. In this way, the history display control unit 136 displays a plurality of execution histories 218 side by side on the extension line in the sliding direction in the sliding operation on the function tab 212. For example, the ordinate at the lower end of the function tab 212 on which the slide operation has been performed may be set as the ordinate at the lower end at which each execution history 218 is displayed. Thereby, it is possible to smoothly shift from the slide operation of the function tab 212 for displaying the execution history to the selection operation of the execution history.

  It is assumed that the user of the electronic device 10 holds the left side surface of the electronic device 10 with the left hand and holds the right side surface of the electronic device 10 with the right hand. Further, it is assumed that the slide operation of the function tab 212 is performed with the thumb of the left hand and the execution history is selected with the thumb of the left hand or the right hand. By making the display position of the function tab 212 and the display position of the execution history the same height on the screen, the user's line of sight smoothly moves to the execution history, and the execution history selection operation following the slide operation The operability can be improved.

  As shown in FIGS. 10 and 11, the history display control unit 136 displays a character string indicating the execution history diagonally. Thereby, even when the character string of the execution history 218 is long, the entire character string of the execution history 218 can be easily stored on the history screen 216 and displayed. When a part of the character string of the execution history 218 does not fit in the history screen 216, that part is not displayed.

The operation of the above configuration will be described below.
FIG. 12 is a flowchart showing the operation of the electronic device 10.
