  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<Explanation of the entire communication system 1>
FIG. 1 is a diagram showing a configuration example of a communication system 1 in the present embodiment.
As illustrated, the communication system 1 of the present embodiment is configured by connecting a terminal device 30a and a terminal device 30b via a network 70 and an access point 90.
Further, hereinafter, when the terminal device 30a and the terminal device 30b are not distinguished from each other, they may be simply referred to as "terminal device 30".

The terminal device 30 can be, for example, a robot. This robot is placed in the residence of the user who owns the robot.
FIG. 2 is a diagram illustrating a case where the terminal device 30 is a robot.
The terminal device 30 as a robot shown in FIG. 2 may be a mobile type having a function of moving by walking or the like, or may be a non-mobile type that does not move.
The terminal device 30 outputs a sound such as a communication antenna 301 that transmits and receives transmission information, a camera 302 that captures a moving image, a microphone 303 that acquires sound, a display 304 that displays transmission information, and a sound. The speaker 305, an operation button 306 operated by the user, a human sensor 307 for detecting the presence or absence of a person around the terminal device 30, and a control unit 308 for controlling the entire terminal device 30. The operation buttons 306 include a recording button 306a for recording, a reproduction button 306b for reproducing transmitted transmission information, and a menu button 306c for setting the terminal device 30 and the like.

  The network 70 is a communication means used for information communication between the terminal devices 30, and is, for example, the Internet.

The access point 90 is a device that performs wireless communication with a network 70 that performs wired communication using a wireless communication line. The access point 90 mediates transmission and reception of information between the terminal device 30 and the network 70.
As the types of wireless communication lines, mobile phone lines, PHS (Personal Handy-phone System) lines, Wi-Fi (Wireless Fidelity), Bluetooth (registered trademark), ZigBee, UWB (Ultra Wideband) lines can be used. Is.

Next, the general operation of the communication system 1 will be described.
First, the user A, who is an example of one user who owns the terminal device 30a, creates transmission information. The transmission information is electronic information used when exchanging information between the terminal device 30a and the terminal device 30b. The transmission information is, for example, information about a moving image, which will be described in detail later. Further, the user A creates a message to the user B, which is an example of another user who owns the terminal device 30b, by using a moving image. The user A and the user B are predetermined persons and have a predetermined friendship relationship. For example, a parent-child relationship or a friend relationship.

  The moving image can be created by the user A speaking to the terminal device 30a and taking a picture with the camera 302 at this time. Specifically, for example, the user A holds the terminal device 30a with his / her hand and turns his / her face to a position facing the camera 302. Then, when the user A presses the record button 306a of the operation buttons 306, the camera 302 records only while the user presses the record button 306a. When the user wants to stop recording, he / she can let go of the recording button 306a. Further, at this time, since sound is acquired by the microphone 303, a moving image with sound is acquired. Then, while the user A is pressing the record button 306a, the user A speaks what he / she wants to convey to the user B by his / her voice. It should be noted that the user A can freely select an object to be captured by the camera 302. In this case, the user B may point the camera 302 at the object to be viewed and add a voice. The object to be photographed is, for example, a photograph, food, a landscape of the garden, or the like. This moving image is stored in the memory of the control unit 308.

Then, the control unit 308 transmits this moving image information as transmission information to the terminal device 30b. The transmission information is sent to the terminal device 30b via the communication antenna 301, the access point 90, and the network 70.
In the terminal device 30b, the communication antenna 301 receives this transmission information, and the control unit 308 acquires it. The control unit 308 stores this transmission information in the memory. At this time, the robot may be separately provided with a light emitting source such as an LED, and the light emitting source may be blinked to notify the user B that the transmission information has arrived from the user A. Further, the human sensor 307 may detect the user B, and when the user B is detected, the speaker 305 may output a guide indicating that the transmission information has arrived from the user A.

  User B can reproduce the transmission information. Specifically, the user B presses the play button 306b of the operation buttons 306. As a result, the moving image transmitted from the user A is displayed on the display 304, and the sound accompanying the moving image is output from the speaker 305. Thereby, the user B can browse the message transmitted from the user A.

  Then, the user B creates transmission information for replying to the user A. The method of creating the transmission information is the same as the method described in the case of the user A described above.

Then, the control unit 308 transmits this moving image information as transmission information to the terminal device 30a. The transmission information is sent to the terminal device 30a via the communication antenna 301, the access point 90, and the network 70.
In the terminal device 30a, the communication antenna 301 receives this transmission information, and the control unit 308 acquires it. The user A reproduces the transmission information sent from the user B.
Then, the same operation is repeated thereafter. That is, the transmission information is exchanged between the user A and the user B.

  Next, the detailed functional configuration and operation of the communication system 1 according to the present embodiment will be described.

<Description of functional configuration of communication system 1>
FIG. 3 is a block diagram showing a functional configuration example of the communication system 1.
Here, among various functions of the communication system 1, those relevant to the present embodiment are selected and shown.
In the communication system 1, the terminal device 30 includes a transmission / reception unit 31 for transmitting / receiving transmission information, a storage unit 32 for storing transmission information, a display unit 33 for displaying an image, a photographing unit 34 for photographing, and a user. The operation unit 35 that receives the operation of 1, the person detection unit 36 that detects the user, the selection unit 37 that selects the transmission information, and the display control unit 38 that controls the display of the image.

  The transmission / reception unit 31 is an example of a reception unit, and another user receives transmission information from one user. The transmission / reception unit 31 is an example of a transmission unit, and transmits transmission information of a reply to another user of another user. The transmission / reception unit 31 is, for example, a communication I / F and is included in the control unit 308. The communication antenna 301 is also included in this. The transmission / reception unit 31 transmits / receives transmission information between the terminal devices 30 via the access point 90 and the network 70.

  The storage unit 32 is an example of a storage unit and stores the received transmission information. The storage unit 32 also outputs this when necessary. The storage unit 32 is, for example, a memory, a HDD (Hard Disk Drive), an SSD (Solid State Drive), or the like, and is included in the control unit 308.

  The display unit 33 is an example of a display unit, and displays the accumulated transmission information by an operation of another user. The display unit 33 is, for example, a liquid crystal display. The display unit 33 corresponds to the display 304 and the speaker 305. The display unit 33 displays the transmission information and, in the case of a moving image, outputs the sound accompanying the moving image. The display unit 33 is not limited to a liquid crystal display, and may be an organic EL (OEL: Organic Electro-Luminescence) display, a projector, a cathode ray tube, a plasma display, or the like.

The image capturing unit 34 captures an image of a device that is a capturing target. The photographing unit 34 corresponds to the camera 302 and the microphone 303. The image capturing unit 34 includes an optical system that converges an image of a subject to be captured, and an image sensor that detects the image converged by the optical system.
The optical system is configured by a single lens or a combination of a plurality of lenses. For example, a twin lens in which two hemispherical lenses are used and their spherical surfaces are face-to-face combined is used. Various unnecessary aberrations are properly removed by the combination of lenses and the coating on the lens surface. The image sensor is configured by arranging image pickup devices such as CCD (Charge Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor).

  The operation unit 35 receives a user operation. The operation unit 35 corresponds to the operation button 306. In addition, the operation unit 35 may be configured by a keyboard, a mouse, or the like. Further, the operation unit 35 may be a touch panel. When the operation unit 35 is a touch panel, it has the functions of both the display unit 33 and the operation unit 35 described above.

  The human detection unit 36 detects the presence or absence of a user. The human detection unit 36 corresponds to the human sensor 307. The human detection unit 36 is not particularly limited as long as it is a human sensor that can detect a person. For example, it is possible to use a pyroelectric sensor that detects that a person has entered a predetermined region by detecting infrared rays of a specific wavelength emitted by a person using the pyroelectric effect. Further, an infrared reflection type reflection type sensor having a light emitting element composed of an infrared light emitting diode and the like and a light receiving element which receives the reflected light when the light emitted from the light emitting element is reflected by a person can be used.

  The selection unit 37 selects the transmission information designated by the user. The selection unit 37 is included in the control unit 308. In the present embodiment, the transmission information is, for example, a moving image, but text, a stamp, or the like can be selected as well. Therefore, the user selects the transmission information from these, and the selection unit 37 accepts it. The transmission information may include information on the date and time when the transmission information was created.

  The display control unit 38 is an example of a display control unit, which will be described in detail later, but the display control unit 38 stores in the storage unit 32 after making a previous reply when there is no reply from one user to another user. The control for continuously displaying the transmitted information is performed.

<Explanation of the operation of the communication system 1>
Next, the operation of the communication system 1 of the present embodiment will be described in more detail.
FIG. 4 is a flowchart illustrating an example of the operation of the communication system 1 of this embodiment.
First, the user A operates the operation unit 35 of the terminal device 30a to select the type of transmission information (step 101). The selection result is acquired by the selection unit 37, and the type of transmission information is determined (step 102). The type of transmission information is at least one of moving picture, text, and stamp. Actually, the user A presses the menu button 306c described in FIG. 2 and selects a moving image or the like from the displayed menu. Here, a case where the user A selects a moving image will be described below.

Next, the user A operates the operation unit 35 to take a moving image with the imaging unit 34 (step 103). Actually, the user A presses the record button 306a shown in FIG. 2 and uses the camera 302 and the microphone 303 to shoot a moving image with sound.
Then, the moving image information is stored in the storage unit 32 as transmission information (step 104). Further, the transmission / reception unit 31 directs the transmission information to the terminal device 30b and transmits it (step 105). At this time, the transmission / reception unit 31 transmits the transmission information of the type selected by the user B. Actually, the control unit 308 shown in FIG. 2 performs transmission via the communication antenna 301.

The transmission information transmitted from the terminal device 30a is transmitted to the terminal device 30b via the access point 90 and the network 70, and the transmission / reception unit 31 of the terminal device 30b acquires the transmission information (step 106). Then, the sent transmission information is stored in the storage unit 32 (step 107).
Then, the human detection unit 36 determines whether or not the user B can be detected (step 108).
As a result, if it cannot be detected (No in step 108), the process returns to step 108.
On the other hand, if it can be detected (Yes in step 108), the fact that the transmission information has arrived is notified to the user B by voice (step 109). Actually, the control unit 308 receives the transmission information via the communication antenna 301 of FIG. 2 in the terminal device 30b and stores it. In addition, when the human sensor 307 detects the user B, the speaker 305 informs that the transmission information has arrived by voice or the like. That is, when the user B is present, the notification is given, but when the user B is not present, it waits until the user B returns.

  The stored transmission information is displayed and reproduced on the display unit 33 by the user B operating the operation unit 35 (step 110). If the user B does not operate the transmission information, the transmission information remains stored without being reproduced, and if new transmission information is further transmitted, the transmission information is sequentially stored. Further, as will be described later in detail, the moving image reproduced at this time is determined by the display control unit 38. Actually, when the user B presses the play button 306b shown in FIG. 2, the moving image is displayed on the display 304, and the sound accompanying the moving image is output from the speaker 305.

  User B who viewed the moving image creates transmission information for replying to user A, and transmits the transmission information to user A. This can be done in the same way as described for User A above. As a result, the same operation is repeated, and the transmission information is exchanged between the user A and the user B. In addition, in the present embodiment, the transmission / reception unit 31 connects the terminal device 30a of the user A and the terminal device 30b of the user B in a one-to-one relationship.

As the transmission information, the user may select a text or a stamp instead of the moving image.
5A and 5B are diagrams showing the display contents displayed on the display 304 of the terminal device 30b.
Of these, FIG. 5A illustrates a case where a moving image is displayed on the display 304. In this case, for example, the moving image Gd of the user A shooting himself is displayed.
Further, FIG. 5B shows a case where the text and the stamp are displayed on the display 304. In this case, the content of the interaction between the user A and the user B is displayed by the text Tx that also uses the stamp St. In this case, “□□□” is the name of the user A and “XX” is the name of the user B.
The text and the stamp can be input, for example, by using the display 304 as a touch panel and operating a touch keyboard displayed on the touch panel. Further, the present invention is not limited to this, and the input can be performed by a keyboard or the like connected to the terminal device 30 in a wired or wireless manner.

Here, for example, the user B may not reproduce the transmission information, and a plurality of transmission information from the user A may be accumulated. That is, since the user A can send the transmission information to the user B regardless of the reply from the user B, the user A may send the next transmission information without waiting for the reply from the user B. . In this case, if the user B does not operate, the transmission information is not reproduced and remains stored. Therefore, when new transmission information is further transmitted from the user A, the transmission information is sequentially stored in the storage unit 32. There is a plurality of pieces of transmission information that are accumulated and are not reproduced in the terminal device 30b.
In this case, when the terminal device 30b reproduces only the last transmission information and does not reproduce the previous transmission information at the time of reproduction, the message of the user A loses continuity, and the user B displays the message of the user A. May not understand the contents of.
Therefore, in the present embodiment, in order to suppress this, the display control unit 38 controls the transmitted transmission information to be reproduced as follows.

6 and 7 are sequence diagrams showing the transmission information to be reproduced.
Of these, FIG. 6 shows a case where either the user A or the user B makes a reply each time transmission information is transmitted. In this case, a series of processes of creating transmission information, transmitting transmission information, receiving / storing the transmission information, and reproducing the transmission information are alternately performed between the user A and the user B. In this case, the transmission information A0, the transmission information B0, the transmission information A1, and the transmission information B1 are alternately exchanged between the user A and the user B.
In this case, the display control unit 38 reproduces the immediately preceding one piece of transmission information shown in the reproduction range (1) shown in FIG.

On the other hand, FIG. 7 shows a case where the transmission information transmitted from the user A is accumulated without being reproduced by the user B. In this case, the transmission information A1 to A3, which is three pieces of transmission information, is sent from the user A, but the transmission information A1 to A3 is accumulated because the user B did not reproduce the transmission information and did not reply. Is shown. Then, at this stage, the case where the user B reproduces the transmission information is shown.
In this case, the display control unit 38 performs control to continuously display the transmission information accumulated in the storage unit 32 after the previous reply. That is, the three pieces of transmission information A1 to A3 shown in the reproduction range (2) shown in FIG. 7 are reproduced. As a result, as compared with the case where only the last transmission information A3 is reproduced, the message of the user A has continuity, and the user B can easily understand the content of the message sent from the user A.

8 and 9 are sequence diagrams showing another example of the transmitted information to be reproduced.
Of these, FIG. 8 is similar to FIG. 7 regarding the transmission information. However, the display control unit 38 reproduces not only the transmission information accumulated and transmitted from the user A, but also the last transmission information returned by the user B to the user A. That is, not only the three pieces of transmission information A1 to A3 are reproduced, but also the last transmission information B0 returned by the user B to the user A is reproduced. In the figure, this range is shown as a reproduction range (3). That is, in this case, in many cases, since the user B has sent the transmission information B0, a corresponding time has elapsed. Therefore, the user B may forget about the content of the transmission information B0. Therefore, the content of the transmission information B0 previously sent to the user A can be remembered by reproducing the message last sent to the user A together with the message. As a result, the continuity of the exchange of transmission information between the user A and the user B is further improved.

Further, FIG. 9 is similar to FIG. 8 regarding the transmission information. However, when the user A makes a reply to the user B, the display control unit 38 makes a reply including the information about the accumulated transmission information. The information regarding the accumulated transmission information may be the accumulated transmission information A1 to A3 itself, and may be any information that can identify the transmission information A1 to A3 such as the time when the transmission information A1 to A3 was transmitted. As a result, the terminal device 30a on the user A side reproduces the transmission information of the three pieces of transmission information A1 to A3 and the transmission information B1 shown in the reproduction range (4). Regarding the transmission information A1 to A3, when the transmission information A1 to A3 itself is transmitted as the information regarding the transmission information, the terminal device 30b on the user B side reproduces it as it is. When the transmission information A1 to A3 is information such as the time when the transmission information A1 to A3 is transmitted, the transmission information A1 to A3 is transmitted to the terminal device 30a as described in step 104 of FIG. Since it is stored, it is played back.
The transmission information B1 is a reply to all the transmission information A1 to A3, and the user A reproduces the transmission information A1 to A3 sent by the user A together with the transmission information B1 so that the user A and the user B can communicate with each other. The continuity of the exchange of transmission information between them is further improved.

  In the case of FIGS. 6 to 9, the display control unit 38 displays the last transmission information of the transmission information accumulated and transmitted from the user A at the normal speed, and transmits the transmission information other than the last transmission information. The information may be displayed at a speed faster than usual. That is, when the user B replies to the user A, what is most needed is the latest and last transmission information, and others may not be so important. Therefore, the display control unit 38 performs the above-described control, quickly reproduces the transmission information other than the last transmission information, and reduces the time burden on the users A and B.

<Modification 1>
Hereinafter, modified examples will be described.
FIG. 10 is a sequence diagram showing the first modification example.
Similar to FIG. 7, FIG. 10 illustrates a case where user B does not reproduce the transmission information transmitted from user A but accumulates the transmission information A1 to A3, which is three pieces of transmission information, as a result of accumulation. ing. Then, it is indicated that the display control unit 38 of the terminal device 30b of the user B has notified the terminal device 30a of the user A. This notification is sent when the operation for displaying the received transmission information has not been performed for a predetermined time or longer. That is, if the user B does not reply for a predetermined time or longer, there is a possibility that some unexpected situation has occurred for the user B. Therefore, in this case, the terminal device 30b notifies the terminal device 30a of the user A to notify the user A of the attention.

FIG. 11: is the figure which showed the example of the notification performed in the 1st example of a modification.
This notification is displayed on the display 304 of the terminal device 30a of the user A. In this case, the notification T1 is displayed on the display 304, as "Not a reply from Mr. ○○○ for more than XX days. Please contact Mr. ○○ by phone etc.". In this case, Mr. XX is user B, and XX days are the above-mentioned predetermined time.

<Modification 2>
In the second example of the modified example, the display control unit 38 of the terminal device 30b of the user B performs the notification as in the first example of the modified example. However, the notification is sent when the received transmission information is accumulated in a predetermined number or more. That is, if the user B does not reply even though the transmission information has accumulated a predetermined number or more, there is a possibility that some unexpected situation has occurred for the user B. Therefore, also in this case, the terminal device 30b notifies the terminal device 30a of the user A so as to alert the user A.

FIG. 12 is a diagram showing an example of the notification performed in the second modified example.
This notification is displayed on the display 304 of the terminal device 30a of the user A, as in the first modified example. Here, as the notification T2 on the display 304, "A message that has been sent to Mr. ○○○ has been accumulated. Please contact Mr. ○○○ by phone etc." is displayed. In this case, the ΔΔ pieces are the above-mentioned predetermined number.

  If the user B cannot reply, he or she may be absent for a certain period due to a trip or the like. Therefore, it is preferable that this function can be switched ON / OFF on the side of the terminal device 30b. ON is a case where this function is valid, and OFF is a case where this function is invalid. Specifically, for example, the menu button 306c described in FIG. 2 is pressed to select ON / OFF of this function from the displayed menu.

  According to the communication system 1 described in detail above, when the user B does not reply to the user A, the transmission information accumulated in the accumulating means after the last reply is continuously displayed. This makes it possible to provide the communication system 1 in which the intention of the other party can be easily determined. Further, according to Modifications 1 and 2, when an unexpected situation occurs in the user B, this can be estimated and the user A can be alerted. That is, it is possible to provide the watching system for the user B.

Further, in the embodiment described in detail above, the communication system 1 is configured by connecting the terminal device 30 via the network 70 and the access point 90, but even with only one terminal device, the transmitting / receiving unit 31, It can be regarded as a communication system including the storage unit 32, the display unit 33, and the display control unit 38.
Furthermore, in the above-described example, the terminal device 30 is an example that is a robot, but the present invention is not limited to this. For example, it may be a mobile computer, a mobile phone, a smartphone, a mobile terminal such as a tablet, or a desktop computer.
Furthermore, in the above-described example, the terminal device 30a and the terminal device 30b are connected peer-to-peer via the network 70 and the access point 90, but the connection is not limited to this, and they are connected via a server. Good. In this case, the processing performed by the terminal device 30a and the terminal device 30b can be also performed by the server. Therefore, this server can be regarded as a reproduction system.
In the communication system 1 described above, it is one user A who operates the terminal device 30a and one user B who operates the terminal device 30b, but the present invention is not limited to this. It is not a thing, and a plurality of terminals 30a and 30b may be operated. For example, this applies to the case where the family operates the terminal device 30a or the terminal device 30b.

<Explanation of program>
Here, the processing performed by the terminal device 30 according to the present embodiment described above is prepared as a program such as application software. Then, this processing is realized by the cooperation of software and hardware resources.
