[0011] Embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0012] 1. Overview This disclosure proposes a new form of information transmission. Information transmission can be considered as a type of mobility, similar to "people's movement" and "vehicle movement." In other words, this disclosure proposes a new form of "information movement (InfoMobility)."

[0013] As an example, consider the transmission of information about "human presence" (Telepresence). For example, there may be a need to communicate one's presence to a person in a distant location, or a need to feel the presence of a person in a distant location. There may also be a need for people in distant locations to feel each other's presence. However, in the past, in order to transmit information to a person in a distant location, it was necessary to launch an application such as a phone or email each time. It would be desirable to transmit information about "human presence" without using a phone or email.

[0014] Fig. 1 is a conceptual diagram for explaining an overview of information transmission according to the present embodiment. Here, two people, a first person P-1 and a second person P-2, who are in distant locations, are considered. The same applies to the case of three or more people. Typically, the first person P-1 and the second person P-2 are acquaintances.

[0015] The first area AR-1 is an area used by the first person P-1. The second area AR-2 is an area used by the second person P-2. The first area AR-1 and the second area AR-2 are separated from each other. Each area is not particularly limited, but examples include a room, a house, a building, an office, a garden, etc. Note that the first person P-1 may be present in the first area AR-1 at times, but does not need to be present there all the time. Similarly, the second person P-2 may be present in the second area AR-2 at times, but does not need to be present there all the time.

[0016] Consider a case where a certain action (movement) is performed by a first person P-1 present in a first area AR-1. According to this embodiment, when the action by the first person P-1 is a predetermined action, a "change" that can be recognized by the second person P-2 automatically occurs in the second area AR-2. This "change" is hereinafter referred to as a "reaction." In other words, when the first person P-1 performs a predetermined action in the first area AR-1, a reaction automatically occurs in the distant second area AR-2 in response to the predetermined action.

[0017] For example, when the predetermined action is "turning on the light in the room", the reaction is "lighting a lamp such as an LED". As another example, when the predetermined action is "opening a door", the reaction is "making a sound". As yet another example, when the predetermined action is "walking in the room", the reaction is "fluttering of fabric such as curtains". Figures 2 and 3 show various examples of the correspondence between predetermined actions and reactions. As shown in Figures 2 and 3, reactions can be realized in various forms such as light, vibration, sound, wind, temperature / heat, silhouette, touch, scent, and ON / OFF switch. The form of the reaction is arbitrary as long as it can be recognized by humans.

[0018] Thus, according to this embodiment, in response to a predetermined action of the first person P-1 in the first area AR-1, a reaction that can be recognized by the second person P-2 automatically occurs in the second area AR-2. This allows the second person P-2 to casually feel the presence of the first person P-1 who is in a distant location. In other words, it becomes possible to suddenly feel the presence of the other person even if you are not talking to them directly. It can also be said that this embodiment conveys a "presence" or "atmosphere."

[0019] The content of the reaction may be the same as or similar to the content of the predetermined action. For example, when the predetermined action is "turning on the light in the room," the reaction may be "a lamp such as an LED lighting up." In this case, the second person P-2 can "directly" know the content of the action of the first person P-1. Furthermore, the first person P-1 and the second person P-2 can share the same experience in separate locations.

[0020] The content of the reaction can be of a different type than the content of the predetermined action. Since there is no need to match the action and the reaction, there are fewer constraints, more freedom in design, and the system is easier to implement.

[0021] The content of the reaction may be set to be reminiscent of the content of a specific action. For example, when the action is "walking in a room," the reaction may be "the swaying of curtains or other fabric." In this case, the second person P-2 can "indirectly" know the content of the action of the first person P-1. Furthermore, since there is no need to match the action and the reaction, there are fewer constraints, the scope of design is broadened, and the system is easier to introduce.

[0022] According to this embodiment, it is not necessary to start communication means such as telephone, e-mail, video conference, etc., in order to transmit information. The presence and atmosphere are automatically transmitted without starting such communication means.

[0023] An information transmission system for realizing information transmission according to this embodiment will be described below.

[0024] 2.Information transmission system 4 is a block diagram showing a configuration example of an information transmission system 1 according to this embodiment. The information transmission system 1 transmits information between a first area AR-1 and a second area AR-2. The information transmission system 1 includes an ith sensor 10-i and an ith notification device 20-i (i=1, 2) installed in an ith area AR-i.

[0025] The ith sensor 10-i is a sensor used to detect the action of the ith person Pi in the ith area AR-i. Any type of sensor can be used as long as it can detect the action. For example, the ith sensor 10-i may be a camera, a door opening / closing sensor, a contact sensor, a weight sensor, a temperature sensor, a switch ON / OFF sensor, etc. A plurality of types of ith sensors 10-i may be installed in the ith area AR-i to detect various actions.

[0026] The ith notification device 20-i is a device for generating a reaction in the ith area AR-i. As described above, the reaction can be realized in various forms such as light, vibration, sound, wind, temperature / heat, silhouette, touch, scent, switch ON / OFF, etc. The type of the ith notification device 20-i is not important as long as it can realize such a reaction. For example, the ith notification device 20-i may be a light source (e.g., LED, electric light), a display, a vibration device, a haptic device, a speaker, a wind generating device, a heat source, a projection device, a scent generating device, an electric device, etc. A plurality of types of the ith notification device 20-i may be installed in the ith area AR-i to realize various reactions.

[0027] The information transmission system 1 further includes a control system 100 that controls the information transmission. The control system 100 is capable of communicating with the i-th sensor 10-i and the i-th notification device 20-i. The control system 100 may be installed outside the i-th area AR-i, or may be installed inside the i-th area AR-i. The control system 100 may be configured with one or more servers. The multiple servers may perform distributed processing.

[0028] More specifically, the control system 100 includes one or more processors 110 (hereinafter simply referred to as processor 110) and one or more storage devices 120 (hereinafter simply referred to as storage devices 120). The processor 110 executes various processes. For example, the processor 110 includes a CPU (Central Processing Unit). The storage device 120 stores various information. Examples of the storage device 120 include a volatile memory, a non-volatile memory, a HDD (Hard Disk Drive), and an SSD (Solid State Drive).

[0029] The control program 130 is a computer program executed by the processor 110. The processor 110 executes the control program 130 to realize the functions of the control system 100. The control program 130 is stored in the storage device 120. Alternatively, the control program 130 may be recorded in a computer-readable recording medium.

[0030] The processor 110 communicates with the ith sensor 10-i and acquires the ith sensor detection information SEN-i obtained by the ith sensor 10-i. For example, the ith sensor detection information SEN-i includes an image or video captured by a camera. As another example, the ith sensor detection information SEN-i may include a physical quantity (e.g., weight, temperature, etc.) detected by the ith sensor 10-i. As yet another example, the ith sensor detection information SEN-i may include information suggesting an action of the ith person Pi (e.g., door opening / closing, switch ON / OFF). The processor 110 detects an action of the ith person Pi in the ith area AR-i based on the ith sensor detection information SEN-i.

[0031] The processor 110 generates a reaction when the detected action is a predetermined action. The correspondence information 140 indicates the correspondence between the predetermined action and the reaction (see Figs. 2 and 3). This correspondence information 140 is created in advance by a system designer and provided to the control system 100. The correspondence information 140 is stored in the storage device 120. The processor 110 determines whether the detected action is a predetermined action based on the correspondence information 140. If the detected action is a predetermined action, the processor 110 understands the content of the reaction associated with the predetermined action based on the correspondence information 140.

[0032] In the following explanation, "j" means either "1" or "2" other than "i." In other words, if "i" is "1," then "j" is "2." If "i" is "2," then "j" is "1."

[0033] The processor 110 selects a j-th notification device 20-j capable of implementing a reaction associated with a predetermined reaction. Then, the processor 110 causes the j-th notification device 20-j to execute the reaction. More specifically, the j-th instruction information INS-j is information that instructs the j-th notification device 20-j to execute a reaction. The processor 110 communicates with the j-th notification device 20-j and transmits the j-th instruction information INS-j to the j-th notification device 20-j. The j-th notification device 20-j installed in the j-th area AR-j executes a reaction according to the j-th instruction information INS-j.

[0034] In this way, in response to a predetermined action performed in the i-th area AR-i, the processor 110 causes the j-th notification device 20-j in the j-th area AR-j to execute a reaction associated with the predetermined action, thereby making it possible to convey a sense of presence or atmosphere.

[0035] The management information 150 is information used to manage the information transmission service. For example, the management information 150 includes user information on a first person P-1 and a second person P-2 who are users of the information transmission service. The user information may include a user ID, a name, contact information, and the like. The management information 150 is stored in the storage device 120. Examples of the use of the management information 150 will be described later.

[0036] Various embodiments relating to information transmission will be described below.

[0037] 3. First embodiment FIG. 5 is a conceptual diagram for explaining an overview of the information transmission process according to the first embodiment.

[0038] An action performed by a first person P-1 in the first area AR-1 is hereinafter referred to as a "first action." The first action is detected based on the first sensor detection information SEN-1 obtained by the first sensor 10-1. When the first action is a first predetermined action, a "first reaction" associated with the first predetermined action is executed by the second notification device 20-2 in the second area AR-2. The content of the first reaction may be the same as or of the same type as the content of the first predetermined action. The content of the first reaction may be of a different type from the content of the first predetermined action. The content of the first reaction may be set so as to be reminiscent of the content of the first predetermined action.

[0039] An action performed by the second person P-2 in the second area AR-2 is hereinafter referred to as a "second action." The second action is detected based on the second sensor detection information SEN-2 obtained by the second sensor 10-2. When the second action is a second predetermined action, a "second reaction" associated with the second predetermined action is executed by the first notification device 20-1 in the first area AR-1. The content of the second reaction may be the same as or of the same type as the content of the second predetermined action. The content of the second reaction may be of a different type from the content of the second predetermined action. The content of the second reaction may be set so as to be reminiscent of the content of the second predetermined action.

[0040] 4. Second embodiment Fig. 6 is a conceptual diagram for explaining an overview of the information transmission process according to the second embodiment. Descriptions that overlap with those of the second embodiment explained in Fig. 5 will be omitted as appropriate.

[0041] The second person P-2 recognizes the first reaction performed in the second area AR-2 and performs a second action in response (reply) to it. If the second action is a second predetermined action in response to the first reaction, the second reaction is performed in the first area AR-1. For example, the first person P-1 walks in the first area AR-1 (first action), and a silhouette is displayed in the second area AR-2 (first reaction). Furthermore, the second person P-2, seeing the silhouette, waves his / her hand (second action), and a lamp lights up in the first area AR-1 (second reaction).

[0042] Similarly, the first person P-1 may recognize the second reaction performed in the first area AR-1 and perform a first action in response thereto. If the first action is a first predetermined action in response to the second reaction, the first reaction is performed in the second area AR-2.

[0043] According to the second embodiment, the other person's reaction to one's own action is also transmitted, which improves interactivity and enhances a sense of solidarity.

[0044] 5. Third embodiment 5-1. Overview There may be cases where a first person P-1 and a second person P-2 who are in different locations perform the same action (e.g. opening the refrigerator, turning on the TV, etc.) at the same time. If they could know this fact from each other, it would be a great opportunity to start communication (e.g. calling, e-mail, chatting). Therefore, in the third embodiment, we propose an information transmission process that can promote communication.

[0045] FIG. 7 is a conceptual diagram for explaining an overview of the information transmission process according to the third embodiment. The first action is an action performed by a first person P-1 in a first area AR-1. The second action is an action performed by a second person P-2 in a second area AR-2. In the following description, "synchronized occurrence" means that the first action and the second action are the same predetermined action (e.g., opening a refrigerator, turning on a television, etc.) and are performed synchronously. The first action and the second action being performed synchronously means that the first action and the second action are performed at the same timing or almost the same timing. In other words, the first action and the second action being performed synchronously means that both the first action and the second action are performed within a period of about several seconds.

[0046] When a synchronization occurs, the information transmission system 1 notifies both the first person P-1 and the second person P-2 of the occurrence of the synchronization. This process is hereinafter referred to as a "synchronization occurrence notification process." The synchronization occurrence notification process may be performed by using the i-th notification device 20-i, or may be performed by using a dedicated device. For example, the occurrence of a synchronization is notified by means of light, sound, vibration, etc.

[0047] The synchronization occurrence notification process allows both the first person P-1 and the second person P-2 to know that a synchronization has occurred. The first person P-1 and the second person P-2, who know that a synchronization has occurred, can use it as a trigger to easily start communication (e.g., phone calls, emails, chats). In other words, the synchronization occurrence notification process increases the likelihood that the first person P-1 and the second person P-2 will start communication. In other words, the synchronization occurrence notification process promotes communication. The synchronization occurrence notification process also increases the sense of solidarity.

[0048] 5-2. Configuration example Fig. 8 is a block diagram showing an example of the configuration of an information transmission system 1 according to the third embodiment. Description of the same configuration as that shown in Fig. 4 will be omitted as appropriate.

[0049] The information transmission system 1 includes an ith synchronism occurrence notification device 30-i (i=1, 2) installed in an ith area AR-i. The ith synchronism occurrence notification device 30-i is used to notify the ith person Pi of a synchronism occurrence. For example, the ith synchronism occurrence notification device 30-i may be a light source (e.g., LED, electric light), a display, a vibration device, a haptic device, a speaker, etc. The ith synchronism occurrence notification device 30-i may be common to the ith notification device 20-i. The processor 110 of the control system 100 is capable of communicating with the ith synchronism occurrence notification device 30-i.

[0050] The information transmission system 1 may further include an ith interaction device 40-i installed in the ith area AR-i. The ith interaction device 40-i is a device used by the ith person Pi for interaction. Examples of the ith interaction device 40-i include a smartphone, a tablet, a smart speaker, and a personal computer. The processor 110 of the control system 100 is capable of communicating with the ith interaction device 40-i. The ith interaction device 40-i is used in the interaction promotion process (see Section 5-4) described below.

[0051] The information transmission system 1 may further include an ith projection device 50-i installed in an ith area AR-i. The ith projection device 50-i can project an image or video into the ith area AR-i. The processor 110 of the control system 100 can communicate with the ith projection device 50-i. The ith projection device 50-i is used in the synchronous projection process (see Section 5-5) described later.

[0052] 5-3. Synchronization notification process The processor 110 detects a first action of a first person P-1 in a first area AR-1 based on the first sensor detection information SEN-1 obtained by the first sensor 10-1. The processor 110 also detects a second action of a second person P-2 in a second area AR-2 based on the second sensor detection information SEN-2 obtained by the second sensor 10-2. Furthermore, the processor 110 determines whether the first action and the second action are the same predetermined action and are performed synchronously. The predetermined action is, for example, registered in advance in the correspondence information 140.

[0053] If the first action and the second action are the same predetermined action and are performed synchronously, the processor 110 determines that synchronization has occurred and executes a synchronization occurrence notification process. Specifically, the processor 110 issues an instruction to the first synchronization occurrence notification device 30-1 and the second synchronization occurrence notification device 30-2 to activate both the first synchronization occurrence notification device 30-1 and the second synchronization occurrence notification device 30-2. This makes it possible to notify both the first person P-1 and the second person P-2 of the synchronization occurrence.

[0054] 5-4. Dialogue promotion processing The processor 110 may execute a dialogue promotion process in conjunction with the above-mentioned synchronization occurrence notification process. Specifically, in the dialogue promotion process, the processor 110 issues an instruction to the first dialogue device 40-1 and the second dialogue device 40-2, and automatically connects the first dialogue device 40-1 and the second dialogue device 40-2 so that they can communicate with each other. When the i-th dialogue device 40-i is OFF, the processor 110 may remotely start the i-th dialogue device 40-i. By automatically connecting the first dialogue device 40-1 and the second dialogue device 40-2 in conjunction with the synchronization occurrence notification process, the first person P-1 and the second person P-2 can immediately start dialogue. In other words, dialogue is promoted.

[0055] Alternatively, taking into consideration the convenience of the first person P-1 and the second person P-2, the processor 110 may first inquire of the first person P-1 and the second person P-2 about their intention to start a dialogue. Specifically, the processor 110 transmits a "dialogue start inquiry" requesting approval for starting a dialogue to the i-th dialogue device 40-i in conjunction with the synchronicity occurrence notification process. The i-th dialogue device 40-i notifies the i-th person Pi of the dialogue start inquiry. If the i-th person Pi approves the start of a dialogue, the processor 110 operates the i-th dialogue device 40-i to input the i-th approval intention information. The i-th dialogue device 40-i sends the input i-th approval intention information to the control system 100. If the processor 110 receives the i-th approval intention information within a certain time from the dialogue start inquiry, the processor 110 determines that the start of a dialogue has been approved by the i-th person Pi. When the start of dialogue is approved by both the first person P-1 and the second person P-2, the processor 110 issues an instruction to the first dialogue device 40-1 and the second dialogue device 40-2 to automatically connect the first dialogue device 40-1 and the second dialogue device 40-2 so that they can communicate with each other. This also has the effect of promoting dialogue.

[0056] 5-5. Synchro projection processing As described above, the synchronization occurrence notification process enhances a sense of community. In order to further enhance the sense of community, a "synchronous projection process" for projecting an image of the other person may be executed in conjunction with the synchronization occurrence notification process.

[0057] More specifically, the i-th sensor 10-i installed in the i-th area AR-i includes the i-th camera that captures the i-th person Pi. The i-th sensor detection information SEN-i includes an image captured by the i-th camera.

[0058] In the synchronous projection process, the processor 110 projects at least a part of the image of the first person P-1 captured by the first camera onto the second area AR-2. For this purpose, the second projection device 50-2 installed in the second area AR-2 is used. The processor 110 transmits at least a part of the image of the first person P-1 to the second projection device 50-2 and instructs the second projection device 50-2 to project the image. By looking at the first person P-1 projected onto the second area AR-2, the second person P-2 can more clearly recognize that the first person P-1 is performing the same action as him / her. This further enhances the sense of solidarity.

[0059] Similarly, the processor 110 projects at least a part of the image of the second person P-2 captured by the second camera onto the first area AR-1. For this purpose, the first projection device 50-1 installed in the first area AR-1 is used. The processor 110 transmits at least a part of the image of the second person P-2 to the first projection device 50-1 and instructs the first projection device 50-1 to project the image. By looking at the second person P-2 projected onto the first area AR-1, the first person P-1 can more clearly recognize that the second person P-2 is performing the same action as the first person P-1. This further enhances the sense of solidarity.

[0060] The first action position is a position where the first action (predetermined action) is performed by the first person P-1. The second action position is a position where the second action (predetermined action) is performed by the second person P-2. In the synchronous projection process, the processor 110 may project at least a part of the image of the first person P-1 onto the second action position in the second area AR-2. Similarly, the processor 110 may project at least a part of the image of the second person P-2 onto the first action position in the first area AR-1. For example, consider a case where the predetermined action is "opening a refrigerator." When the first person P-1 opens the refrigerator in the first area AR-1, an image of the second person P-2 opening the refrigerator is projected onto the position of the refrigerator (first action position). Similarly, when the second person P-2 opens the refrigerator in the second area AR-2, an image of the first person P-1 opening the refrigerator is projected onto the position of the refrigerator (second action position). By projecting an image superimposed on the action position in this way, the synchronous projection process becomes more effective.

[0061] 5-6. Synchronization points Each user (first person P-1, second person P-2) of the information transmission service may be given points. In this case, the processor 110 also manages the points given to each user. The management information 150 also includes information on the points given to each user.

[0062] An example of points is a synchronization point that is given each time a synchronization occurs. The processor 110 increases the synchronization points of the first person P-1 and the second person P-2 in conjunction with the synchronization occurrence notification process. As the number of synchronization occurrences increases, the synchronization points also increase.

[0063] Processor 110 may dynamically change the method of notifying the occurrence of a synchronization depending on the synchronization points. For example, as the synchronization points increase, the method of notifying the occurrence of a synchronization becomes more elaborate. As another example, as the synchronization points increase, the variety of the method of notifying the occurrence of a synchronization may increase. This creates a game-like element and also increases motivation to increase the synchronization points. As a result, synchronization is promoted, and communication is further promoted.

[0064] 6. Fourth embodiment 9 is a conceptual diagram for explaining an overview of the information transmission process according to the fourth embodiment. As an example, consider a case where a predetermined action is "going to bed" and a reaction associated with the predetermined action is "turning on a lamp."

[0065] According to the first and second embodiments described above, when the first person P-1 in the first area AR-1 goes to sleep, the lamp in the second area AR-2 lights up. However, depending on the state of the second person P-2, it may not be appropriate to light up the lamp (reaction). For example, if the second person P-2 is not present in the second area AR-2, lighting up the lamp would be a waste of electricity. As another example, if the second person P-2 is sleeping in the second area AR-2, lighting up the lamp may disturb the sleep of the second person P-2.

[0066] Therefore, in the fourth embodiment, a reaction is executed under certain conditions. Specifically, when the action performed by the first person P-1 is a predetermined action, the processor 110 first recognizes the state of the second person P-2 based on the second sensor detection information SEN-2 obtained by the second sensor 10-2.

[0067] For example, the processor 110 determines whether or not a second person P-2 is present in the second area AR-2 based on the second sensor detection information SEN-2.

[0068] As another example, the processor 110 may determine whether the second person P-2 in the second area AR-2 is awake or asleep based on the second sensor detection information SEN-2. There are various examples of methods for determining whether a person is awake or asleep. For example, if a person is present in a bedroom and the bedroom light is turned off, the person is determined to have gone to sleep. As another example, if a person is present in the bedroom and the bedroom door is not opened or closed for a certain period of time, the person is determined to have gone to sleep.

[0069] Next, the processor 110 determines whether or not a reaction permission condition is satisfied based on the state of the second person P-2. For example, the reaction permission condition includes that the second person P-2 is present in the second area AR-2. As another example, the reaction permission condition may include that the second person P-2 in the second area AR-2 is not asleep but is awake. As yet another example, the reaction permission condition may include that a reaction is explicitly permitted by the second person P-2.

[0070] When the reaction permission condition is satisfied, the processor 110 causes the second notification device 20-2 in the second area AR-2 to execute a reaction. On the other hand, when the reaction permission condition is not satisfied, the processor 110 prohibits (refrains) the second notification device 20-2 from executing a reaction. This prevents unnecessary reactions and excessive reactions. As a result, waste of power is prevented, and the second person P-2 is prevented from feeling annoyed.

[0071] 7. Fifth embodiment FIG. 10 is a conceptual diagram for explaining an overview of the information transmission process according to the fifth embodiment. In the fifth embodiment, the predetermined action is "watering a plant", and the reaction is also "watering a plant". That is, when a first person P-1 waters a first plant in a first area AR-1, water is automatically supplied to a second plant in a distant second area AR-2. Similarly, when a second person P-2 waters a second plant in a second area AR-2, water is automatically supplied to a first plant in a distant first area AR-1. The first plant and the second plant may be the same species or different species.

[0072] More specifically, the ith notification device 20-i installed in the ith area AR-i includes the ith automatic watering device 21-i. The ith automatic watering device 21-i supplies water to the ith plant in the ith area AR-i. The ith automatic watering device 21-i is realized by, for example, a water supply tank and a water supply pump.

[0073] The ith sensor 10-i installed in the ith area AR-i includes an ith water supply amount sensor 11-i. The ith water supply amount sensor 11-i is installed in the ith plant in the ith area AR-i and detects the ith amount of water supplied to the ith plant. The ith sensor detection information SEN-i obtained by the ith sensor 10-i includes the ith amount of water supplied to the ith plant in the ith area AR-i.

[0074] For example, a first person P-1 in a first area AR-1 waters a first plant (a predetermined action). The processor 110 detects that water has been supplied to the first plant in the first area AR-1 based on the first sensor detection information SEN-1. In response to this, the processor 110 issues an instruction to the second automatic watering device 21-2 in the second area AR-2 to supply water to the second plant in the second area AR-2 (a reaction).

[0075] The ratio between the first water supply amount to the first plant and the second water supply amount to the second plant may be determined in advance. For example, if the appropriate water supply amount to the first plant per day is X and the appropriate water supply amount to the second plant per day is Y, the ratio between the first water supply amount and the second water supply amount is X:Y. The processor 110 acquires information on the first water supply amount from the first sensor detection information SEN-1, and calculates the second water supply amount based on the first water supply amount and the ratio. Then, the processor 110 instructs the second automatic watering device 21-2 in the second area AR-2 to supply water to the second plant by the second water supply amount. This makes it possible to supply water to the second plant without excess or deficiency.

[0076] If the first person P-1 overwaters the first plant, the second amount of water to be supplied to the second plant may be excessive accordingly. Therefore, the processor 110 may monitor the second amount of water to be supplied to the second plant based on the second sensor detection information SEN-2. When the second amount of water to be supplied reaches the appropriate amount of water to be supplied per day Y, the processor 110 may stop issuing a water supply instruction to the second automatic watering device 21-2. In other words, when the second amount of water to be supplied reaches the appropriate amount of water to be supplied per day Y, the processor 110 may stop executing the reaction. This prevents excessive water from being supplied to the second plant.

[0077] The same is true in the reverse direction, i.e. when a second person P-2 waters a second plant.

[0078] The reaction may include watering the plant as well as causing the plant to flutter.

[0079] The fifth embodiment can be applied to things other than "watering plants." For example, the fifth embodiment can be applied to "feeding animals." Examples of animals include dogs, cats, birds, and goldfish. In a higher conceptualization, the fifth embodiment can be applied to "raising living things." In the above explanation, "plants" can be replaced with "living things," "water" can be replaced with "substances necessary for the life activities of living things," and "amount of water supplied" can be replaced with "amount of material supplied." The information transmission system 1 can also be called an "living thing raising system."

[0080] According to the fifth embodiment, people who are far apart can be connected to each other through raising creatures. For example, a first person P-1 can have the sense that he is raising a first creature in a first area AR-1 and also a second creature in a distant second area AR-2. A second person P-2 can have the sense that the first person P-1 is raising the second creature for him. In the case of a two-way communication, the sense of connection can be strengthened by both people being involved in caring for each other's creatures.
