Description

  The present invention relates to a message display terminal, a message management server, a message display system, a message display method, and a message display program for easily displaying messages constituting a thread.

  The display on the electronic bulletin board on the Web is simply arranged in chronological order, managed by a tree structure for each thread, and the evaluation (moderation) for each comment is given by the user, and only comments with a certain evaluation value or more are extracted. There are many things to display. However, when browsing an electronic bulletin board on the Web with a device with a limited UI (user interface) such as a mobile phone or a TV, it is difficult to use because it is premised on clicking with a mouse for an existing PC.

  For example, a bulletin board is an asynchronous communication tool, and each message written constitutes a thread associated with the original message and a reply message in a parent-child relationship. Therefore, if the message is simply displayed in time series while ignoring the thread on the bulletin board, it becomes difficult to understand the context of the message.

  In order to solve such problems, citations are frequently made in e-mails. In addition, a device for displaying a message in a tree structure according to a thread is also performed. However, when the display area is limited, it is difficult to quote long sentences or display the thread structure. Mobile phones have a physically small display and low resolution. A TV display is physically large, but the resolution may not be high. In addition, since the scroll operation does not match the TV UI, it is difficult to display a long quote or a long thread structure by scrolling like a PC. These devices are strongly required to have good visual quality and simple operability.

  FIG. 24 is a diagram showing a display example of a message in the conventional bulletin board browsing software. FIG. 24 shows a display state of the parent message based on the thread information. In this software, messages are basically displayed in chronological order. As shown in FIG. 24 (a), message numbers are assigned to each message in chronological order, and the user normally quotes the message number as ">> 312" when replying to a message. So that the message of the reply destination can be understood. Since messages are displayed in ascending order by message number, if the user scrolls to display the smaller number side, the message 312 that is the citation source of the message 348 can be found. However, the scrolling operation is troublesome. In addition, it is troublesome to return to the same position after confirming the parent message.

  Therefore, this software analyzes the thread and sets a pop-up for the corresponding message at the quoted part like “>> 312”. When the user wants to refer to the parent message, the original message is automatically popped up by simply placing the pointer on the quoted portion (FIG. 24B). The user can easily know the context of the thread. The pop-up disappears automatically when you move the pointer away from the quote. The pop-up can be displayed in multiple stages, and the original message can be further displayed from the quoted part in the pop-up (FIG. 24C). Similar processing may be realized by a script operating on a Web browser.

  Such a UI allows easy thread information reference, but is assumed to be used by a PC. Therefore, a mouse operation is required on a high-resolution screen, and it is difficult to handle an interface mainly for key input such as a mobile phone or a TV.

On the other hand, although not intended for messages, UI technology on TV has been disclosed for browsing images and selecting commands (see, for example, Patent Document 1). In addition, a display method is disclosed that enables a user to intuitively understand a hierarchical structure that is hierarchized to manage content (see, for example, Patent Document 2).
JP 2004-356774 A JP 2007-122562 A

  However, it is assumed that the objects handled in Patent Document 1 or 2 are classified into groups and accessed for each group. A user accesses an object while moving between groups having a tree structure.

  On the other hand, each interface for a message has attribute information such as time information, and is required to be able to list all messages regardless of the thread to which the message belongs by arranging them in time series. Also, from the viewpoint of convenience, since messages having new times are often more important, it is basically required to display the latest messages in chronological order. However, each message may constitute a thread having a relationship of an original message and a reply message to the original message, and it may be desired to follow the thread in order to understand the meaning of the message. In such a scene, the user refers to the thread information as necessary while accessing messages arranged in time series. Since the character of the object to be handled is different in this way, it is not appropriate to apply the method as disclosed in the prior document as it is. On the other hand, if a complicated operation is required, convenience is lost.

  The present invention has been made in view of such circumstances, and the user traces a thread of messages displayed in a row according to individual information such as date and time using an input interface with two types of inputs, and is simple. The purpose is to make it easy to check messages related to.

  (1) In order to achieve the above object, a message display terminal of the present invention includes a message recording unit that records a message, individual information of the message, and correlation information, and a message display unit that displays the recorded message. A display target determining unit that determines the message to be displayed based on the individual information of the message, and a predetermined reference position by changing the message to be displayed according to the first input A reference message changing unit for changing the reference message displayed on the screen, and extracting a related message related to the reference message based on the correlation information of the reference message according to a second input; A related message extraction unit that displays the related message by superimposing or replacing the related message. The sage extraction unit displays the related message while the second input is maintained, and suppresses the display of the related message when the maintenance of the second input is released. It is said.

  Thereby, the user can check the messages displayed in time series based on information such as the posting date of the message, for example, while switching the reference message by the first input. If the messages are arranged in the order of arrival, you can read unread messages just by checking the necessary messages from the top.

  Also, if you want to check the related message while checking the message, the related message is displayed while the second input continues, so you can easily check the history and the flow of the message. it can. Thereafter, if the second input is released, the display of the related message is suppressed, so that the original message browsing can be easily resumed. After the user confirms the related message, the display is automatically returned to the original state by releasing the pressed button. Since the user can operate with only the first input and the second input, navigation is easy. Since the message to be displayed and the reference message are determined by the first input, other selection operations are not necessary, and if there is the second input as a single input, the related message can be displayed. Therefore, the operation can be sufficiently performed with the cursor keys, and a means for aligning the cursor position with the message as in the pointing device is not necessarily required.

  When a long message is included in the display target, it is preferable to display only a part of the message without displaying the entire message. Even if the full text is not displayed, the message is displayed. In addition, the correlation information is information for specifying the relationship between messages of parent or child, and the related message is a parent or child message with respect to the reference message. Note that the suppression of the display includes not only the disappearance of the display but also a display that is reduced, translucent, moved to the side, or sunk in the back.

  (2) In the message display terminal of the present invention, the reference message changing unit changes the reference message to the related message being displayed in response to a predetermined input made during the display of the related message. It is characterized by.

  When the related message is displayed superimposed or replaced with the reference message, if there is a predetermined input, the related message being displayed is changed to the reference message, and the steady state is restored. Then, a message to be displayed is determined corresponding to the reference message, and a message column is displayed on the screen. The predetermined input is, for example, a decision key input.

  If there are a plurality of related messages to be displayed, one of them is selected and used as a new reference message. Thereby, for example, the user can follow the thread in the parent direction or the child direction in multiple stages. Even if the reference message is moved to the parent message or the child message, the message is displayed in time series in a steady state. For example, it is possible to view the message using only the up and down keys (first input) of the cursor keys. It becomes.

  (3) Further, in the message display terminal according to the present invention, the display target determining unit is associated with the correlation information of the reference message according to a predetermined input made when the second input is not made. A message group to be displayed is extracted as a thread, and a message to be displayed is determined in the extracted thread.

  Thereby, the user can extract and browse only the thread to which the reference message belongs by a simple operation. In that case, the reference message does not change before and after extraction. Further, for example, it is preferable that the thread can be confirmed while changing the reference message only with the up and down keys (first input) of the cursor key. Moreover, it is preferable to return to the original display before extraction by predetermined input again. A thread is a group of messages that are related to each other based on the correlation information.

  (4) Further, the message display terminal of the present invention is characterized in that the related message extraction unit extracts parent messages as the related messages by using parent-child relationship information as the correlation information of the messages. As a result, the user can easily confirm the parent message traced back from the message being browsed.

  (5) Further, the message display terminal of the present invention is characterized in that the related message extraction unit uses parent-child relationship information as the correlation information of the message and extracts a child message as the related message. Thereby, the user can confirm the child message derived from the message being browsed.

  (6) The first input and the second input have different directivities, and the reference message changing unit corresponds to the first input in accordance with the first input. And changing the message to be displayed, and the related message extracting unit responds to one direction of the second input in accordance with the second input, and sets the parent message as the related message. A child message is extracted as the related message in correspondence with the other direction of the second input. Thereby, the user can operate the display of the message according to the image received from each directionality of the first input and the second input. As a result, operation becomes easy and convenience as a user interface is improved.

  (7) Further, the message management server of the present invention analyzes a message, specifies a message analysis unit that identifies individual information and correlation information of the message, and accumulates the analyzed message and the individual information and correlation information. A message accumulation unit, and a message extraction unit for transmission that extracts a part of the accumulated set of messages based on the individual information and the correlation information of the message according to the message request instruction received from the message display terminal; The extracted message and its individual information and correlation information are transmitted to the message display terminal.

  As described above, the message management server of the present invention specifies and accumulates a message and accompanying information from the received mail or the like, so that a simple message can be written. Further, a part of the message set is transmitted to the message display terminal in response to the message request received from the message display terminal. Therefore, a set of messages can be transmitted for each request, and the burden on the message display terminal can be reduced.

  (8) Further, the message display system of the present invention stores and manages the posted message with the message display terminal described above, and sends a message to the message display terminal in response to a request from the message display terminal. And a server. With such a system, it is possible to provide a bulletin board service that allows easy confirmation of history and message flow.

  (9) Further, the message display method of the present invention is a message display method performed by using a message display terminal for recording a message and individual information and correlation information of the message and displaying the recorded message. The step of determining the message to be displayed based on the individual information of the message and the message to be displayed are changed in accordance with the first input, so that the message is displayed at a predetermined reference position. In response to the second input, the reference message is extracted based on the correlation information of the reference message, and the related message related to the reference message is extracted and superimposed or replaced with the reference message. Displaying the related message; and while the second input is maintained, the related message. Displays di, triggered by the freed maintenance of the second input, and characterized in that it comprises a step of suppressing the display of the related messages. As a result, it is possible to provide a bulletin board service that can easily check the history on the thread and the flow of messages.

  (10) The message display program of the present invention is a message display program for recording a message, individual information of the message and correlation information, and causing the message display terminal to display the recorded message. Based on the individual information of the message, it is displayed at a predetermined reference position by changing the message to be displayed in accordance with the process of determining the message to be displayed and the first input. In response to a process of changing the reference message and a second input, the related message related to the reference message is extracted based on the correlation information of the reference message, and is superimposed on or replaced with the reference message. While the related message is displayed and the second input is maintained, the related message is displayed. Display over di-, triggered by the maintenance of the second input is released, it is characterized by comprising a process of suppressing the display of the related messages. As a result, it is possible to provide a bulletin board service that can easily check the history on the thread and the flow of messages.

  (11) Further, the message management server of the present invention analyzes a message, specifies a message analysis unit that identifies individual information and correlation information of the message, and accumulates the analyzed message and the individual information and correlation information. A message accumulation unit, and a message extraction unit for transmission that extracts a part of the accumulated set of messages based on the individual information and the correlation information of the message according to the message request instruction received from the message display terminal; A page generation unit that generates the program as a page using the extracted message and its individual information and correlation information, and generates the generated program into a message display terminal capable of executing the generated program; Each extracted page and the extracted message and its individual It is characterized by sending a multi-address and interrelated information.

  As described above, the message management server of the present invention generates and transmits a page to be displayed on the message display terminal. Therefore, it is not necessary to generate a page on the message display terminal side, and the burden on the message display terminal can be reduced.

  According to the present invention, the user can easily confirm the history and the message flow while confirming the displayed message based on the individual information. Then, the display of the parent message can be suppressed and message browsing can be resumed immediately. As a result, it is possible to provide a bulletin board service that can easily check the history and the flow of messages.

  Next, embodiments of the present invention will be described with reference to the drawings. In order to facilitate understanding of the description, the same reference numerals are given to the same components in the respective drawings, and duplicate descriptions are omitted.

[Embodiment 1]
(Configuration of message display system)
FIG. 1 is a diagram illustrating an example of the configuration of the message display system 100. The message display system 100 includes a message management server 110, a message display terminal 140, mail receiving servers 171, 173, and mail transmitting servers 172, 174.

  The message management server 110 manages messages posted on the bulletin board. The message management server 110 transmits a managed message to the message display terminal 140 based on a request from the message display terminal 140. Access from the message display terminal 140 to the message management server 110 can be performed using http or https. The message management server 110 manages a message written by a user from a form by Web access by the user. The message management server 110 also manages the individual information of the message and the correlation information.

  The message management server 110 defines the appearance of the Web page based on a posted message received from the mail receiving server 171 and a resource file such as an icon. Then, a script describing the interaction with the input is embedded and transmitted to the message display terminal 140. In addition to the appearance of the message, the Web page transmitted by the message management server 110 includes an operation definition such as displaying a parent message in response to an input. Such an operation may be embedded in HTML in advance or read in advance.

  The message may be acquired by AJAX (Asynchronous JavaScript, registered trademark). In that case, not all messages are embedded in the HTML passed from the message management server 110 to the message display terminal 140, and the message display terminal 140 acquires messages from the message management server 110 asynchronously as necessary.

  The message display terminal 140 displays the Web page received from the message management server 110 with a Web browser. Then, the input is transmitted to the browser, and the thread can be operated according to the script associated with the HTML. In order to facilitate the operation, the above input is preferably a key input. Hereinafter, a case where key input is used as an input means will be described as an example. Further, when the message needs to be updated, a new message is requested to the message management server 110. Message display terminal 140 may be a mobile terminal or a fixed terminal. Examples of the mobile terminal include a mobile phone, a PDA, a portable player, and a portable game machine. Examples of the fixed terminal include a television receiver equipped with a Web browser, a PC, and a home appliance. In FIG. 1, as a message display terminal 140, a terminal connected to a server only by using http or https, and further connected to a mail receiving server 171, 173 and a mail sending server 172, 174, posting and browsing on a bulletin board by mail. The terminal which can do is illustrated.

  When sending mail from the message display terminal 140 and writing on the bulletin board, the message display terminal 140 sends a message to the mail account of the message management server 110 via the mail sending server 174. The message management server 110 periodically checks the mail account via the mail receiving server 171 and receives and records the message.

  On the other hand, the message management server 110 circulates the posted message as an e-mail to the user's e-mail account registered in advance via the e-mail transmission server 172. The message management server 110 performs the same operation as a general mailing list management server with regard to message transmission / reception. The message management server 110 assigns a serial number to the subject for the mail transmitted to the own account, and transfers the mail to the registered account.

  Usually, when a response to a message is written by e-mail, the response source message may not be identified from the description in the text. Even in such a case, by analyzing the header information of the mail, it is possible to grasp the relationship between the messages and manage the messages as threads.

  The message display terminal 140 can confirm a posted message on the bulletin board via the mail receiving server 173. In this manner, the message display terminal 140 can post or browse the bulletin board by sending or receiving mail without accessing the message management server 110. Access by e-mail is not necessarily limited to a mobile terminal, and a fixed terminal may be accessed by e-mail.

  Mail transmission / reception is a standard function of existing mobile phones, and a user can use a bulletin board using familiar mail. On the other hand, in the current use of e-mail on mobile phones, there is a lack of information for understanding the context of the thread, such as subject and e-mail citations, and the mainstream method is to exchange short messages of only the main points in a short time. .

  FIG. 2 is a diagram schematically showing the message display system 100. In the example shown in FIG. 2, the message display terminal 140 is a television receiver. The message display terminal 140 includes a remote controller 190 that can be connected wirelessly, such as infrared rays, and can obtain input information from the remote controller 190. The remote controller 190 transmits a corresponding command (input information) to the message display terminal 140 according to the key input. The message display terminal 140 updates the screen according to the received command and the current client application status. A large number of keys are mounted on the remote controller 190. In FIG. 2, only the up key 191, the down key 192, the right key 193, the left key 194, and the enter key 195 of the cursor key are schematically illustrated. The upper key 191 and the lower key 192 correspond to the first input. The right key 193 and the left key 194 correspond to the second input. Thus, since the first input and the second input have different directions, an intuitive operation is possible, and the convenience for the user is improved.

  In the present embodiment, as the first input and the second input, the input using the independent cursor keys is adopted, but the input may be performed using an integrated cross key or a joystick. Furthermore, the input may be performed with a touch panel having no shape as a key, or the key input may be substituted by detecting the inclination of the casing with a gyro sensor or detecting the acceleration of the casing with an acceleration sensor. Absent. Such a logical input does not affect the physical shape. At this time, it is preferable that the operation direction on the screen is related to the key arrangement because it is easy to handle intuitively. As described above, the message display terminal 140 preferably includes the cursor key, but is not essential. The input unit may be provided on the main body instead of the remote controller.

(Message management server configuration)
FIG. 3 is a functional block diagram showing the configuration of the message management server 110. As shown in FIG. 13, the message management server 110 includes a message reception unit 111, a message analysis unit 112, a thread information management unit 116, a subject management unit 117, a caller information management unit 118, a body text management unit 119, and a media management unit 120. A message storage unit 125, a media storage unit 126, a page request reception unit 131, a transmission message extraction unit 135, a page generation unit 136, a page resource management unit 137, and a page transmission unit 138.

  The message receiving unit 111 receives a message by receiving a mail from the mail receiving server 171, for example. The message analysis unit 112 analyzes a message received as a mail and specifies individual information and correlation information of the received message. Also, the received mail is subjected to processing such as character code conversion and sanitization.

  The message analysis unit 112 includes a header analysis unit 113, a body text analysis unit 114, and a media analysis unit 115, and advances the analysis by instructing each unit to analyze the message. The header analysis unit 113 identifies the sender from the From: header in the mail header, identifies the subject from the Subject: header, and identifies the thread from the Message-ID: header and the References: header. The body analysis unit 114 shapes the message body such as folding quotes, deleting signatures, making links clickable, and thumbnailing attached media, and normalizes them by line feed position correction, font size correction, and the like. The media analysis unit 115 extracts and converts media attached to the message. Note that the medium refers to an expression medium other than the text and attached to the mail, and refers to a still image, a moving image, audio, or the like.

  The thread information management unit 116 normalizes thread information that identifies a thread and causes the message storage unit 125 to store the normalized thread information. The subject management unit 117 normalizes the identified subject and causes the message storage unit 125 to store it. The caller information management unit 118 normalizes caller information for specifying the caller and causes the message storage unit 125 to store the normalized caller information. The text management unit 119 stores the normalized text in the message storage unit 125. The media management unit 120 causes the media storage unit 126 to store the extracted and changed media. Header information, body text, and media information are stored in association with each other. The message storage unit 125 stores the analyzed message and its individual information and correlation information. The media storage unit 126 stores the analyzed media.

  The page request receiving unit 131 receives a page request from the message display terminal 140 through, for example, http or https. In response to the message request received from the message display terminal 140, the transmission message extraction unit 135 extracts a part of the accumulated message set based on the individual message information and the correlation information. For example, messages in the display screen, messages for reading in advance outside the display screen, parent or child messages and media of those messages are extracted. In this way, necessary messages are extracted from the message storage unit 125 and the media storage unit 126 and passed to the page generation unit 136.

  The page generation unit 136 generates a page as a program for displaying on the message display terminal using the extracted message, the individual information and the correlation information, and the medium. For example, the page generation unit 136 combines a web page resource such as an icon, script, or HTML template stored in the page resource management unit 137 with the message and media received from the message storage unit 125 and the media storage unit 126 to create a thread. Configure. Then, a Web page described in HTML and script is generated.

  The page resource management unit 137 accumulates and manages Web page resources such as icons, scripts, and HTML templates. The page transmission unit 138 transmits the Web page generated by the page generation unit 136 to the message display terminal 140. By transmitting the page in this way, the extracted message, its individual information and correlation information, and media are transmitted to the message display terminal 140.

(Message display terminal)
FIG. 4 is a functional block diagram showing the configuration of the message display terminal 140. As shown in FIG. 4, the message display terminal 140 includes a page request unit 141, a page reception unit 142, a page recording unit 143, an input information reception unit 151, a page control unit 152, and a message display unit 168.

  The page request unit 141 requests a page from the message management server 110 according to an instruction from the display target determination unit 154. The page receiving unit 142 receives a page from the message management server 110. The page recording unit 143 records the page received from the message management server 110.

  The input information receiving unit 151 receives a key input from the remote controller. The page control unit 152 refers to the page recording unit 143 to activate a page as a program, and controls each unit by the operation of the page. As a result, it is possible to display a message for the input. The page control unit 152 includes a control instruction unit 153, a display target determining unit 154, a message recording unit 155, a media recording unit 156, a reference message changing unit 157, and a related message extracting unit 158.

  The control instruction unit 153 instructs the display target determination unit 154 to select a new message based on the current screen state and the keyed information, or sends a message to the reference message change unit 157 or the related message extraction unit 158. Instruct to change the display. The display target determination unit 154 determines a message to be displayed based on the individual information of the message. Specifically, a message to be displayed on the screen is selected with reference to the current reference message position. Here, the message to be displayed is selected so that the reference message comes to the center of the screen.

  In addition, the display target determining unit 154 generates a reference according to the input (predetermined input) of the determination key 195 that is made when the right key 193 or the left key 194 of the cursor key is not input (second input). Based on the message correlation information, a related message group is extracted as a thread, and a message to be displayed is determined in the extracted thread. When a new message needs to be acquired, the display target determining unit 154 requests the message management server 110 for a new page through the page request unit 141.

  The message recording unit 155 records the message received from the message management server 110, the individual information of the message, and the correlation information. The media recording unit 156 records media associated with the message.

  The reference message changing unit 157 changes the message to be displayed according to the input (first input) of the up key 191 or the down key 192 of the cursor key, thereby changing the reference displayed at a predetermined reference position. Change the message. That is, in response to an instruction from the control instruction unit 153 according to the input information, the selection of the reference message is changed. For example, in a message displayed in order of arrival from top to bottom in the order of arrival, for the input of the down key 192, the display target is moved down to display the old message, and for the input of the up key 191, Move the display up to display a new message. As described above, it is preferable that the reference message changing unit 157 changes the message to be displayed in a direction corresponding to the first input in accordance with the first input.

  The predetermined reference position is preferable because, for example, the center position is easy to see. The reference message changing unit 157 changes the related message that is displaying the reference message as the reference message in response to the input (predetermined input) of the determination key 195 that is made while the related message is displayed. Note that the first input does not necessarily have to be the input of the up key 191 or the down key 192 of the cursor key, but is preferably the input corresponding to the direction of the column in which the messages are displayed side by side.

  The related message extraction unit 158 extracts a related message related to the reference message based on the correlation information of the reference message according to the input (second input) of the right key 193 or the left key 194 of the cursor key, The related message is displayed by superimposing or replacing the reference message. For example, an instruction from the control instruction unit 153 is received in response to an input of the right key 193 of the cursor key, and the parent message of the reference message can be displayed in a slide-in manner using the parent-child relationship information as the message correlation information. In response to the input of the left key 194, the child message can be displayed in a slide-in manner. As described above, the related message extraction unit 158 extracts the parent message as the related message in accordance with one direction of the second input in accordance with the second input, and sets the other message in the other direction of the second input. Correspondingly, it is preferable to extract a child message as a related message.

  The correlation information is information for specifying the correlation between messages, for example, information for specifying a parent message or a child message of the message, and the related message is, for example, a parent message or a child message. The second input does not necessarily have to be the input of the right key 193 or the left key 194 of the cursor key, but the input of the key corresponding to the direction perpendicular to the direction of the column in which the messages are displayed side by side. It is preferable that

  Further, the related message extraction unit 158 displays the related message while the input (second input) of the right key 193 or the left key 194 of the cursor key is maintained, and the right key 193 or the left key 194 of the cursor key is displayed. When the maintenance of input is released, the display of related messages is suppressed.

  The message display unit 168 displays a screen and displays a message. The message display unit 168 monitors and displays a screen on which a message is finally displayed based on an instruction from the display target determination unit 154, the reference message change unit 157, or the related message extraction unit 158. The monitor may be an external monitor.

(Operation of message display terminal)
FIG. 5 is a flowchart showing the operation of the message display terminal 140. FIG. 5 shows an operation when a related message is displayed. First, it is determined whether or not the right key 193 has been input in a steady state (step S1). If it is determined that the right key 193 has not been input, it is determined whether or not the left key 194 has been input (step S2). If it is determined that the left key 194 has not been input, the process returns to step S1. If it is determined that the left key 194 has been input, it is determined whether there is a child message of the reference message (step S3). If it is determined that no child message exists, the process proceeds to step S14. If it is determined that a child message exists, a display for sliding in the child message from the left side of the screen is performed (step S4), and the process proceeds to step S7.

  On the other hand, if it is determined in step S1 that the right key 193 has been input, it is determined whether there is a parent message of the reference message (step S5). If it is determined that there is no parent message, the process proceeds to step S14. If it is determined that there is a parent message, a display for sliding in the parent message from the right side of the screen is performed (step S6).

  In the above example, the search for the parent or child message is allowed only in one stage. However, when the slide-in display continues for a predetermined time or when the right key or the left key is continuously input in the same direction. Correspondingly, an ancestor (parent's parent, etc.) or descendant (child's child, etc.) message may be searched and displayed in a slide-in manner in multiple stages.

  Next, when either the parent message or the child message is displayed, it is determined whether or not the input of the right key 193 or the left key 194 has been released (step S7). If it is determined that the key input has not been released, the process returns to step S7 in the display state as it is. If it is determined that the key input has been released, it is determined whether or not the enter key 195 has been input (step S8). If it is determined that the enter key 195 has not been input, it is further determined whether or not a predetermined waiting time has elapsed since the key was released (step S9). If it is determined that the standby time has not elapsed, the process returns to step S8. If it is determined that the standby time has elapsed, the slide-in display is canceled (step S10), and the process proceeds to step S14.

  On the other hand, if it is determined in step S8 that the enter key 195 has been input, the slide-in display is canceled (step S11), and the reference message is changed with the currently displayed message as the reference message (step S11). S12). Then, the screen is scrolled so that the reference message is displayed at the center of the screen (step S13), the steady state is restored (step S14), and the operation is terminated.

  As described above, for example, when the message is displayed in time series (steady state), the input information receiving unit 151 detects a key input, and when the input key is the right key, the related message extracting unit 158 displays the parent message. Confirm the existence of. If the parent message exists, the message display unit 168 slides in the parent message from the right side, and if there is no parent message, does nothing. On the other hand, when the input key is the left key, the related message extraction unit 158 confirms the existence of the child message. If a child message exists, the message display unit 168 slides in the child message from the left, and if there is no child message, does nothing.

  When the key is released in a state where the parent or child message is displayed and the input of the determination key 195 is further detected by the input information reception unit 151 before the standby time elapses, the related message extraction unit 158 displays a slide-in display. At the same time, the message that is being displayed is changed to be the reference message, and the reference message is scrolled up and down so that it comes to the center of the screen, and then returns to the steady state. On the other hand, when the standby time has elapsed without the enter key 195 being input, the slide-in display is canceled and the steady state is restored. In this case, there is no change in the reference message.

  In the above example, the reference message is changed by inputting the enter key 195. For example, when the slide-in display continues for a predetermined time or longer, the reference message may be automatically changed to the displayed message. Good. Further, the reference message may be changed to the message being displayed by continuously inputting the right key or the left key in the same direction.

  FIG. 6 is a flowchart showing the operation of the message display terminal 140. FIG. 6 shows an operation when the up cursor key or the down cursor key is pressed in the slide-in state of the related message. First, it is determined whether or not the up key 191 has been input in the slide-in state of the related message (step T1). If it is determined that the upper key 191 has not been input, it is determined whether or not the lower key 192 has been input (step T2). If it is determined that the down key 192 has not been input, the process returns to step T1.

  If it is determined that the down key 192 has been input, it is determined whether there is a message preceding the reference message in the message sequence displayed in time series (step T3). If it is determined that the previous message does not exist, the process proceeds to step T8. If it is determined that the previous message exists, the reference message is changed with the previous message as the reference message (step T4), and the process proceeds to step T7.

  On the other hand, if it is determined in step T1 that the up key 191 has been input, it is determined whether there is a message next to the reference message in time series display (step T5). If it is determined that the next message does not exist, the process proceeds to step T8. If it is determined that the next message exists, the next message is changed as a reference message (step T6). Then, the screen is scrolled so that the reference message is displayed at the center of the screen (step T7), the steady state is restored (step T8), and the operation is terminated. In this way, the presence of the previous or next message is confirmed, and if present, the reference message is changed, and the reference message is scrolled so that it comes to the center of the screen.

  FIG. 7 is a flowchart showing the operation of the message display terminal 140. FIG. 7 shows an operation when the enter key 195 is pressed in a steady state. First, it is determined whether or not the enter key 195 has been input in the steady state (step P1). If it is determined that the enter key 195 has not been input, the process returns to step P1. If it is determined that the enter key 195 has been input, the thread to which the reference message belongs is extracted (step P2) and the thread is displayed. In that case, the thread can be extracted by extracting the message associated with the same thread information using the thread information associated with the reference message. A thread can also be extracted by tracing the information of the parent message to find the original message and extracting the child message and grandchild message of the message.

  Next, it is determined whether or not the enter key 195 has been further input while the thread is displayed (step P3). If it is determined that the enter key 195 has not been input, it is determined whether or not the up key 191 has been input (step P4). If it is determined that the upper key 191 has not been input, it is determined whether or not the lower key 192 has been input (step P5). If it is determined that the down key 192 has not been input, the process returns to step P3. If it is determined that the down key 192 has been input, it is determined whether there is a message preceding the reference message in the message sequence displayed in time series (step P6). If it is determined that the previous message does not exist, the process returns to step P3. If it is determined that the previous message exists, the reference message is changed with the previous message as the reference message (step P7), and the process proceeds to step P10.

  On the other hand, if it is determined in step P4 that the up key 191 has been input, it is determined whether or not there is a message next to the reference message in the message sequence displayed in time series (step S4). P8). If it is determined that the next message does not exist, the process returns to step P3. If it is determined that the next message exists, the reference message is changed with the next message as the reference message (step P9). Then, the screen is scrolled so that the reference message is displayed at the center of the screen (step P10), and the process returns to step P3. If it is determined in step P3 that the enter key 195 has been input, the thread extraction state is canceled (step P11), the steady state is restored (step P12), and the operation is terminated.

  Thus, when the enter key 195 is pressed, only the thread to which the reference message belongs is extracted and displayed. When the enter key 195 is input again in this state, the thread extraction is canceled and the original steady state is restored. When the up / down key is input while the thread is displayed, the reference message is changed. Furthermore, messages may be arranged on the left and right so that a parent or child message can be traced in a thread. Note that a thread may be composed of one message, and in that case, only one message is displayed.

  FIG. 8 is a diagram conceptually illustrating an example of a thread configured by a message. In this example, twelve messages from M0001 to M0012 are recorded in chronological order of message posting date and time, and three threads Th01 to 03 are configured. In the thread Th01, there are three messages M0002, M0003, and M0006 as replies (replies) to the message of M0001, and M0004 and M0007 are recorded as M0004 less. The parent message (reply source message) of M0002 is M0001, and there are three direct child messages (reply messages) of M0001: M0002, M0003, and M0006. There are two child messages, M0004 and M0007, which are not direct.

  FIG. 9 is a schematic diagram showing a series of messages three-dimensionally. In FIG. 9, a message set is displayed using a message number on the x-axis, a temporal order on the y-axis, and a thread type on the z-axis. Hereinafter, an example of operation will be described by taking as an example a set of messages having the relationship shown in FIGS.

(Operation example)
FIG. 10 is a diagram showing an example of mail contents. A message M0005 indicates an example of mail sent from the message management server 110 to the message display terminal 140. In the To header, “bbs@foobar.Net” is shown as the mailing list address, and in the From header, the sender mail account “alice@sharp.net” is shown. “[BBS: 0005] Today” is specified as the Subject, but the subject specified when this mail is sent to the message management server 110 is only “Today”, and “[BBS: 0005] "Is assigned by the message management server 110 at the time of transfer. DATE indicates the mail transmission date and time (message posting date and time), and "Mon, 25 Aug 2008 13: 42: 08 + 0900" is specified. Message-ID is an ID that is uniquely generated and assigned to each mail, and manages threads based on such data.

  A message M0012 shown in FIG. 10 indicates a mail transferred from the message management server 110 that Bob responds to by mail. In the References header, the Message-ID of the reply source mail M0005 is designated. By referring to this header, it can be determined that the mail M0005 is a reply of the mail M0012 and that these mails constitute a thread. Bob's reply is a simple “OK”, and just looking at this email doesn't reveal what is OK. However, by following the thread, it can be seen that this “OK” means that Alice's message M0005 has been accepted. Note that thread analysis may be performed using an In-Reply-To header instead of the References header.

  FIG. 11 is a table showing an outline of a message recorded by the message display terminal 140, individual information of the message, and correlation information. The table shown in FIG. 11 is simplified for convenience. The subject information is information indicating the title of the post, and “Today” and “Re: Today” indicating a reply to the post are recorded. The sender information is information indicating a poster who posted on the bulletin board, and “Bob”, “Alice”, and the like are recorded. The date / time information is information indicating the date / time when the message was posted, and for example, a time such as “14:06” or “13:42” is recorded. The related information is, for example, identification information that identifies the parent or child message of the message. In the example shown in FIG. 11, it is recorded that the parent message of the message M0012 is M0005. In the example shown in FIG. 11, the message number is simplified as the related information, but the actual related information is message identification information.

  FIG. 12 is a diagram illustrating a display example of a message on the message display terminal 140. Messages are displayed in time series on the display screen, and are arranged in the order of arrival, M0012, M0011,. In this example, it is assumed that the number of messages entering one screen is five and that the reference message is always displayed in the center of the screen. Therefore, when the reference message is the message M0012, only three messages M0012 to M0010 are displayed on the screen. At this time, since the source M0005 is outside the screen, the user does not know what Bob is saying "OK" by looking at the message M0012.

  As shown in FIG. 12, messages M0012 and M0005 are different from messages M0011, M0010 and M0009. The mode is determined for each thread to which each message belongs, and the messages of the same thread are controlled to be displayed in the same mode. Thus, for example, the user is prevented from misunderstanding that the reply “OK” of the message M0012 is a response to the message “Do not discard the old album” of the message M0011. The controlled mode includes message display color, background color, message display position (X, Y, Z), font type, size, style, and the like.

  FIG. 13 is a diagram conceptually illustrating an example of a steady state and a state in which a related message is displayed. The message display is a time series display in a steady state. The arrow indicates the slide-in of the message when the corresponding operation is performed (the same applies hereinafter). Of these, the display object determining unit 154 selects the number determined by the display size of the message, the size of the screen, and the like and displays it on the screen. In the example illustrated in FIG. 13, the five messages M0001 to M0005 extracted by the display target determining unit 154 are the display target 700. In that case, it is preferable that the display target determining unit 154 determines to arrange the reference message at the center of the screen. Thereby, the movement of the user's line of sight can be minimized. In FIG. 13, a message M0003 surrounded by a thick line is a reference message. In the following figure, the display message surrounded by a thick line will be described as a reference message.

  In response to the user pressing the up and down cursor keys, the reference message moves from M0003 to M0004 or M0002. Corresponding to the change of the reference message, the display object 700 also changes. When the reference message is the message M0004, the display object 700 is changed to the messages M0002 to M0006. On the other hand, when the reference message is the message M0002, the display target is the messages M0001 to M0004 centered on the message M0002, and the lowermost part is filled with blanks. Note that the position of the reference message may be shifted downward by one on the screen without changing the display object 700 from the messages M0001 to M0005.

  The right column shown in FIG. 13 shows the parent message displayed when the steady-state messages M0001 to M0012 in the center column are used as reference messages. Similarly, the left column shown in FIG. 13 shows child messages that are displayed when the messages M0001 to M0012 in the steady state are used as reference messages. When there is no parent message or child message, no message is displayed even if the corresponding cursor key is pressed. In addition, during the confirmation of the parent or child message, it is effective to prevent the user from being confused by different display such as dimming the display mode of other messages.

  There may be multiple direct child messages in a message thread. As shown in FIG. 13, when there are a plurality of direct child messages, the message display terminal 140 shows only the message with the smallest number (post date and time is old). For example, in the example shown in FIG. 13, there are three direct child messages of the message M0001: messages M0002, M0003, and M0006, but only the message M0002 is shown on the left of the message M0001.

  14A to 14D are diagrams illustrating examples of display and suppression of the parent message of the reference message M0012. FIGS. 14A to 14D show, in time series, display operations when the right key is continuously pressed and then released with respect to the reference message M0012. As shown in FIG. 14A, first, when the user presses the right key, the parent message M0005 of the reference message M0012 is slid in and displayed on the screen from the right side. While the right key is held down, the parent message M0005 is displayed over the reference message M0012 (FIG. 14B). When the right key is released, M0005 slides out (FIG. 14C). The display returns to the display of the original reference message M0012 (FIG. 14 (d)).

  In this way, the user can easily follow the thread and confirm the parent message. When the left key is pressed to check the child message, basically the same display operation is performed, and the child message is displayed by sliding in from the left side. At this time, if there are a plurality of child messages, a plurality of child messages can be displayed.

  As shown in the display examples of FIGS. 14A to 14C, when the upper or lower cursor key is pressed while the parent or child message of the reference message is displayed, the reference message is generated according to the key input. Switches to the steady state. Further, when the decision key 195 is pressed while the message M0005, which is the parent message of the message M0012, is displayed as shown in FIGS. 14A to 14C, the reference message is updated to the message M0005, and the steady message is displayed. The screen shifts to a screen in which the reference message is changed to M0005 in the state.

  FIGS. 15A to 15D are diagrams showing examples of display by a notification function for notifying the presence of a parent message. In the example of FIG. 15A, a part of the parent message M0005 is displayed on the right side of the message M0012. The parent message M0005 may be reduced and displayed as a whole. In the example of FIG. 15B, an arrow sign A1 that prompts the user to press the right key is displayed on the right side of the message. In the example of FIG. 15C, the parent message M0005 is displayed overlapping the right side of the message M0012. In the example of FIG. 15D, the user is notified that the parent message M0005 is present by expressing the fold A2 by folding the upper right of the message. Note that the display examples shown in FIGS. 15A to 15D are examples, and the display by the notification function is not limited to the above example as long as the user can be notified of the presence of the parent message. In the above example, the notification example of the presence of the parent message is described, but it is also possible to notify the presence of the child message in the same manner.

  FIGS. 16A to 16F are diagrams showing examples of displaying child messages in each scene. In the display example shown in FIG. 16A, only the message M0002 is displayed when a direct child message of the message M0001 is displayed. The display may be controlled so that all the child messages M0002, M0003, and M0006 can be confirmed instead of displaying only one message. In addition, the child messages displayed each time the left key 194 is pressed may be switched in the order of messages M0002 → M0003 → M0006, or as shown in FIG. Three child messages may be switched.

  Further, as shown in FIGS. 16C to 16F, it may be displayed so that three child messages can be listed at a time. In FIG. 16C, three messages M0002, M0003, and M0006 are displayed at blank positions, M0001 and M0002, respectively, so as to align the centers as much as possible. On the other hand, in FIG. 16D, the child message of the message M0001 is displayed on the space of M0001 and two messages so that the child messages can be confirmed in the latest order from the center of the reference position. FIGS. 16E and 16F show displays when the time series are arranged in reverse chronological order. Here, only direct child messages are displayed, but grandchild and great-grandchild messages such as messages M0004 and M0007 can also be displayed with respect to the message M0001. Further, when displaying a parent message, not only a direct parent but also a message that becomes a parent of the parent can be displayed. Also, when a plurality of parents are allowed, such as when a message can be created by quoting a plurality of messages, a plurality of messages can be displayed simultaneously as in the above example. In particular, when replacing or superimposing a plurality of messages, it is important to prevent the user from being confused by displaying the messages in a different manner such as by making the display mode of other messages light.

  FIG. 17A is a diagram illustrating a display example of the thread Th02 including the reference message M0012. Similarly, FIG. 17B is a diagram illustrating a display example of the thread Th03 including the reference message M0010. FIG. 17C is a diagram illustrating a display example of the thread Th01 including the reference message M0003.

  Since threads can be extracted in this way, the user can extract and browse only specific threads with a simple operation. The reference message does not change before and after extraction, and the thread to which the reference message belongs can be easily confirmed. For example, in a steady state, the thread corresponding to each reference message can be confirmed while changing the reference message with the up and down keys of the cursor key. In that case, it is possible to return to the original state before extraction by pressing a predetermined key again. At that time, the reference message does not change. For example, in the display state shown in FIG. 17C, when the determination key is pressed while the reference message is the message M0006, the message M0006 is returned to the steady state as the reference message.

  FIG. 18 is a diagram illustrating a display example when a thread including the message M0012 is extracted. When the determination key 195 is pressed with the message M0012 as a reference message, messages M0012 and M0005 are extracted as threads including the message M0012. Thereby, the user can extract and confirm only the thread of interest with a simple operation. If the enter key 195 is pressed again, the original state shown in FIG. 12 is restored. Since the screen is controlled while the reference message is maintained before and after the switching, the user can subsequently confirm the message.
