An outline of the message transmission / reception system 1 including the television receiver 10z which is a message transmission / reception terminal will be described with reference to FIGS. FIG. 1 is a block diagram showing an outline of the configuration of the television receiver 10z. Although details will be described later, the television receiver 10z includes a bus line 11, a control unit (determination unit, key invalidation unit and change unit) 12, a communication unit 13, a display unit (display unit) 14, and an input unit (input). Means) 15, a storage unit 16, an analysis unit (analysis unit) 17, a key assignment unit (key assignment unit) 18, an answer selection unit (answer selection unit) 19, and a chat client 20. The input unit 15 includes a remote controller 15a and a light receiving unit 15b.

  As shown in FIG. 2, the television receiver 10z is connected to the message transmission / reception server 60 via the Internet, for example. Hereinafter, the message transmission / reception server 60 is simply referred to as a server 60. The server 60 is also connected to a PC (personal computer) 10a and a smartphone 10b. The PC 10a, the smartphone 10b, and the television receiver 10z connected to the server 60 are also simply referred to as clients. There are multiple clients and there is no upper limit.

  In the message transmission / reception system 1, each client transmits / receives a text-based message to / from each other via the server 60. Various tools such as e-mail, SMS, text chat, electronic bulletin board, and message transmission / reception service provided by SNS (Social Networking Service) can be considered as tools for transmitting / receiving text-based messages. In the present embodiment, a text chat is described as an example of the message transmission / reception tool, but other message transmission / reception tools described above may be used. In the following, the text chat is simply expressed as chat, and the message transmission / reception system 1 is also expressed simply as chat system 1.

  In this embodiment, a user who uses the PC 10a is described as a user A, a user who uses the smartphone 10b is described as a user B, and a user who uses the television receiver 10z is a user Z. It describes.

(client)
Each client is not limited to the PC 10a, the smartphone 10b, and the television receiver 10z. Any information terminal that can be connected to the server 60 via a telecommunication network and can input characters can be used as a client. The character input means for inputting characters is a keyboard for a PC, a touch panel for a smartphone, and a remote control for a television receiver. Of these input means, the remote controller is not good at character input.

  The main target of the present invention is a client including an input means that is not good at character input like a remote controller. In other words, the present invention aims to make it easier to reply to a received message using such a client. Therefore, in the present embodiment, the television receiver 10z will be described as an example of a client.

  The server 60 only needs to have a general function as a chat server. Therefore, the description thereof is omitted in this embodiment.

(Messages to be sent and received)
The message transmitted / received in the chat system 1 is a text-based message. In many cases, a message to be transmitted for communication with other users includes some question for a transmission partner (recipient). “How is your physical condition?”, “What was your day today?”, “Would you like to participate in tomorrow's golf?” Etc. are examples of messages that include questions.

  In addition, even when a message that includes a direct question is sent instead of some message, the sender often expects a reply from the receiver. For example, suppose that a sender sends a message “I will be there tomorrow at 9 am”. In this case, the message sent by the sender does not contain a clear question, but the sender expects a reply from the receiver (eg, “I understand”). This is because the sender can confirm that the receiver has read the transmitted message by receiving a reply from the receiver.

  In the present embodiment, a message including the above-described question items and a message expecting a reply from the recipient are collectively expressed as a message including a question. When the sender creates a message including a question, the sender sets an expected answer or an expected answer as the wording of the answer. For a single question included in the message, one or more answer words may be set. One message may contain a plurality of questions.

  The message includes information on the user account that identifies the sender and receiver of the message, in addition to the above-described question and the wording of the answer set for the question. Information about the user account that identifies the sender and recipient of the message may be included in the attribute information of the message. The attribute information of the message only needs to include information used by a general chat system in addition to the information related to the user account.

The control unit 12 includes a microprocessor unit including a CPU (Central Processing Unit), a memory, a timer, and the like. A control program stored in a storage unit 16 to be described later is read into a memory provided in the control unit 12. Then, when the CPU executes the control program, the control unit 12 controls the operation of each unit included in the television receiver 10z. Specifically, the control unit 12 transmits / receives a message by a communication unit 13 to be described later, displays a message by a display unit 14, a message of an answer and a specific key, and assigns a specific key to the message of an answer by a key allocation unit 18. The selection of an answer by the answer selection unit 19 and the creation of a message by the chat client 20 are controlled.

(Communication unit 13)
The communication unit 13 receives messages transmitted from other clients from the server 60 via the Internet. The communication unit 13 outputs the received message to the storage unit 16. In addition, a message including the answer input from the answer selection unit 19 is transmitted to the server 60. The operation of the communication unit 13 is controlled by the control unit 12.

(Input unit 15)
As shown in FIG. 1, the input unit 15 includes a remote controller (input unit) 15a and a light receiving unit 15b. The remote controller 15a outputs an operation signal corresponding to a user operation by infrared rays. The light receiving unit 15b receives infrared rays output from the remote controller 15a and outputs an operation signal converted into an electric signal to the control unit 12. As shown in FIG. 4, the remote controller 15a includes number keys 1 to 12, color keys B (blue), R (red), G (green), and Y (yellow), and a P (power) key. ing.

The key provided in the input means may be either a hardware key or a software key. Examples of input means different from the remote control include a keyboard and a touch panel. The keyboard is an input unit that is good at character input, and the touch panel is also an input unit that is good at character input. However, it is not easy for a user who is not familiar with the keyboard and touch panel to input characters using these input means. Even when a user who is not familiar with character input uses the keyboard and touch panel, by assigning a unique key corresponding to the key of the input means to the wording of each answer, the user can easily answer You can choose a wording.

(Storage unit 16)
As described above, the storage unit 16 stores the control program and sequentially stores messages received by the communication unit 13 and messages created by the chat client 20 described later.

(Analysis unit 17)
The analysis part 17 extracts the wording of the answer set with respect to the question which a message contains by analyzing a message. More specifically, the analysis unit 17 analyzes whether or not there is a phrase enclosed by “[[” and “]]” in the message, and is enclosed by “[[” and “]]”. If there is a wording, the wording is extracted as the wording of the answer. As shown in FIG. 3, the user A transmits a message including the second question “How are you feeling?” And [[OK]] and [[A little painful]]. The analysis unit 17 analyzes the message and extracts “OK” and “Slightly painful” enclosed by “[[” and “]]” as the wording of the answer. The analysis unit 17 outputs the extracted wording of the answer to the key assignment unit 18.

  Note that the notation rule representing the wording of the reply included in the message is not limited to the above-mentioned “[[” and “]]”. For example, identifiers such as “[[1]]” and “[[2]]” may be added to the wording of each answer. The analysis part 17 may extract the word following the said identifier as a word of a reply by detecting these identifiers.

(Key allocation unit 18)
Based on the analysis result of the analysis unit 17, the key allocation unit 18 allocates a unique key within the key range of the remote controller 15 a to each answer word. More specifically, the key assigning unit 18 assigns one of keys 1 to 12, B, R, G, and Y to the wording of each answer.

  As described above, in the message including the first question “Is it still happening?” (See FIG. 3), the key allocation unit 18 selects [[Wake up. ]] Is assigned 1 and [[I'm going to sleep now. ]] Is assigned “2”. Further, in a message including the second question “How is your physical condition?”, The key assigning unit 18 assigns a unique key to the wording of the answer from the keys other than “1” and “2” that have already been assigned. . That is, the key allocation unit 18 selects [[OK. ]] Is assigned to "3" and [[A bit painful. ]] Is assigned “4”.

  Then, the key assigning unit 18 outputs the above-described assignment result (correspondence between the answer text and the unique key) to the storage unit 16 together with the message. The storage unit 16 stores the message and the allocation result.

(Display unit 14)
The display unit 14 includes a display panel typified by a liquid crystal display panel and a driver circuit for driving the display panel. The control unit 12 controls the display unit 14 to display the message stored in the storage unit 16 and the allocation result. The display unit 14 displays a message including a question, an answer word, and a unique key assigned to the answer word according to this control (see FIG. 3). The display unit 14 displays a plurality of messages.

(Answer selector 19)
After reading the message displayed on the display unit 14, the user Z selects a key assigned to the first question and the answer wording set for 2 by operating the remote controller 15a. . More specifically, the key of the remote controller 15a corresponding to the key assigned to the selected answer word is pressed. An operation signal output from the remote controller 15a by this operation is output to the control unit 12 via the light receiving unit 15b. The control unit 12 detects a key pressed by the user Z from the operation signal, and outputs the key to the answer selection unit 19. The answer selection unit 19 selects the answer text to which the key pressed by the user Z is assigned as an answer, and outputs the answer to the chat client 20.

  Referring to FIG. 3, the user Z selects “I'm waking up” from the wording of answers set for the first question, and presses “1” on the remote controller 15a. The control unit 12 receives a control signal indicating that “1” has been pressed, and outputs “1” to the answer selection unit 19. The answer selection unit 19 selects the answer text “I'm waking up” assigned with “1” as an answer, and outputs it to the chat client 20.

(Chat client 20)
The chat client 20 creates a message including the answer selected by the answer selection unit 19 and the information of the user A who is a partner to which this answer is returned, and outputs the message to the communication unit 13. The communication unit 13 outputs this message to the server 60. The chat client 20 only needs to have a function as a general chat client for functions other than creating a message including the answer selected by the answer selection unit 19.

(Key grayed out)
The answer selection unit 19 determines that the first question has been answered because the answer “I am waking up” is selected as the answer, and the determination is made to the control unit 12. Output. In response to the determination, the control unit 12 asks the control unit 14 to gray out the unique keys “1” and “2” assigned to the wording of the answer set for the first question. Output a control signal. In response to the control signal, the control unit 14 grays out “1” and “2”. Graying out in the present embodiment means that a unique key is painted in gray as shown in FIG. By graying out the answer text set for the answered question, the user can easily distinguish between the displayed state of the answered key and the displayed state of the unanswered key. It becomes possible. That is, the user can easily distinguish between answered questions and unanswered questions.

  In the display unit 14 shown in FIG. 3, “1” and “2” are grayed out. Although the grayed out keys are displayed with numbers, the function as a unique key is disabled by the control unit 12. Therefore, even if the user Z presses the “1” or “2” key of the remote controller 15a on the display unit 14 shown in FIG. 3, the control unit 12 sets the control signal input at this time as an invalid control signal. I reckon. In other words, a question in which the key assigned to the wording of the answer is grayed out is a question that the user Z cannot answer.

  On the other hand, in the state shown in FIG. 3, “3” and “4” assigned to the wording of the answer set for the second unanswered question are not grayed out. That is, the user Z can answer the second question by pressing “3” or “4” on the remote controller 15a.

(Key assignment method)
When a certain user (user Z in the present embodiment) receives a plurality of messages including questions, there are several modes for assigning a unique key to the wording of answers set for each question. is there. Here, with reference to FIGS. 5 to 12, a method for assigning a unique key to the answer word and a method for graying out the key added to the answer word will be described.

  FIG. 5 shows a state in which the user Z uses the chat system 1 and receives messages including questions from the user A and the user B. The user Z first receives a message from the user A that includes the question “Do you want to participate in tomorrow's golf?” In the first question, “[[I participate.]] [[I do not participate.]]” Is set as the wording of the answer. Since the third question is the first question displayed on the display unit 14, the key assignment unit 18 selects [[Join. ]] To “1”, [[Not participating. ]] Is assigned to each [2].

  The user Z further receives a message from the user B including the question “Did you take medicine?” (Assumed to be a fourth question). In the fourth question, “[[drinked.]] [[I forgot.]]” Is set as the wording of the answer. The key assigning unit 18 sequentially assigns a unique key that has not been assigned to the wording of the answer to the wording of each answer. That is, the key allocation unit 18 drank the fourth question [[drinked. ]] "3", [[I forgot. ]] Is assigned to “4”.

  The key assigning unit 18 assigns a unique key to the answer text displayed on the display unit 14 in such a manner as not to overlap. Accordingly, the user Z can arbitrarily answer a plurality of questions by a simple operation of pressing a key on the remote controller 15a. When the user Z receives a message including a new question, the key assigning unit 18 sequentially assigns keys after “5” that have not been assigned to the wording of the answer included in the message.

(Processing method 1 after reply)
A processing method when the user answers an arbitrary question will be described with reference to FIG. FIG. 6 shows a state in which the user Z uses the chat system 1 and receives messages including questions from the user A and the user B. The user Z first receives a message from the user A that includes the question “Do you want to participate in tomorrow's golf?” In the fifth question, “[[I will participate.]] [[I will not participate.]]” Is set as the wording of the answer. Since the fifth question is the first question displayed on the display unit 14, the key assignment unit 18 selects [[Participates. ]] To “1”, [[Not participating. ]] Is assigned as a unique key.

  Next, the user Z receives a message from the user B that the weather looks good tomorrow. This message does not include question and answer language. Therefore, the key assigning unit 18 does not assign a key to this message.

  Furthermore, the user Z includes a message including a question “How is your physical condition today?” (Referred to as a sixth question) and a question (referred to as a seventh question) saying “Did you take medicine?” A message is being received. For the sixth question, “[[I'm fine.]] [[Not so good.]]” Is set as the answer word, and for the seventh question, “[[Drinking ]] [[I forgot.]] ”Is set. The key assigning unit 18 sequentially assigns keys that have not been assigned to the words of each answer. In other words, the key assignment unit 18 selects [[I'm fine in the sixth question. ]] To "3", [[Not very good. ]] Is assigned to “4”. Furthermore, the key allocation unit 18 drank the seventh question [[drinked. ]] "5", [[I forgot. ]] Is assigned to [6].

  The key assigning unit 18 assigns the unique keys “1” to “6” to the words of the answers displayed on the display unit 14 in this way, so that the user Z can use the keys on the remote controller 15a. Any question can be answered by a simple operation of pressing. In FIG. 6, when the user Z presses “3” on the remote controller 15 a, the television receiver 10 z returns a message including an answer “How are you today? @User B? @User Z” It shows a state.

  The answer selection unit 19 determines that the sixth question has already been answered because the answer word to which “3” is assigned is selected as the answer, and outputs the determination to the control unit 12. In response to the determination, the control unit 12 instructs the display unit 14 to gray out the unique keys “3” and “4” assigned to the wording of the answer set for the sixth question. Output a control signal. The display unit 14 receives the control signal and grays out “3” and “4”. Therefore, in FIG. 6, “3” and “4” are grayed out. For the answered question, the key of the set answer word is grayed out so that it cannot be selected, thereby preventing the user Z from answering the question that has already been answered by mistake.

(Processing method 2 after reply)
FIG. 7 shows a state where the user Z uses the chat system 1 and receives two messages each containing a question from the user B. In response to the question “How is your physical condition today?” (Assumed to be the eighth question), “[[I'm fine.]] [[Not so good.]]” Is set. The key assignment unit 18 is [[I'm fine. ]] To “1” and [[Not so good. ]] Is assigned to “2”. In addition, in response to the question “Did you take medicine?” (The ninth question), the wording of “[[drinked.]] [[I forgot.]]” Is set. The key allocation unit 18 [[drinked. ]] And assign [3] to [[I forgot. ]] Is assigned to “4” (see FIG. 7A).

  The user Z presses “1” on the remote controller 15a to select the wording “I am fine” for the answer set for the third question. In FIG. 7B, the display unit 14 after the user Z presses “1” on the remote control 15 a and returns a message including an answer “How are you today @User B? @UserZ”. Is shown. At this time, as described above, the key assigned to the wording of the answer set for the eighth question that has been answered is grayed out. Further, the key assigning unit 18 reassigns a unique key to the wording of each answer.

  Specifically, the answer selection unit 19 determines that the eighth question has been answered because “1” of the remote controller 15 a has been pressed, and outputs the determination to the control unit 12.
