[0015] 3. Information Processing FIG. 5 is a sequence diagram showing an example of information processing in the care system 1000. As shown in FIG. When it is determined that the push button 115 has been selected by the care recipient, in sequence SQ501, the control unit 301 of the communication device 110 transmits a connection request to the smartphone 120 to the information processing device 100. The push button 115 is an example of a connection button. Upon receiving a connection request from the communication device 110, in sequence SQ502 and sequence SQ503, the control unit 201 of the information processing device 100 transmits the connection request to each of the smartphones 120 (smartphone 120A, smartphone 120B) that are set as smartphones 120 that can make calls with the communication device 110. The control unit 401 of the smartphone 120 that has received the connection request notifies the user of the incoming call by ringing or vibrating. The processing of sequence SQ502 and sequence SQ503 is an example of processing for calling each of the smartphones 120 of the multiple users set when a connection request based on the selection of the push button 115 of the communication device 110 is received.

[0016] In this embodiment, it is assumed that the user of the smartphone 120A (caregiver A) answers the call. Caregiver A is an example of a first user. When the call is responded to, the control unit 401 of the smartphone 120A transmits a call response to the information processing device 100 in sequence SQ504. When the call response is received, the control unit 201 of the information processing device 100 ends the call to the smartphone other than the smartphone 120A (the smartphone 120B in this embodiment). Then, in sequence SQ505, the control unit 201 of the information processing device 100 connects the communication device 110 and the smartphone 120A to enable video calling. The sequence SQ505 in FIG. 5 indicates that a two-way call is possible between the communication device 110 and the smartphone 120A via the information processing device 100.

[0017] Here, an example of a screen related to a video call displayed on the smartphone 120A is shown in Fig. 6. Fig. 6 is a diagram (part 1) showing an example of a screen related to a video call displayed on the smartphone 120A. When a detailed setting button 601 is selected, a detailed setting screen is displayed. In an area 602, an image of the care recipient captured by the imaging unit 303 of the communication device 110 is displayed. That is, when the communication device 110 and the smartphone 120A of the caregiver A are connected, the control unit 201 enables the captured image captured by the imaging unit 303 of the communication device 110 to be displayed on the smartphone 120A of the caregiver A. When the call ON / OFF button 603 is selected, a call with the care recipient is started. When an incoming call is notified and the user selects the call ON / OFF button 603 to answer the call, the user selects the button. The screenshot save button 604 is a button for saving a screenshot of the image of the care recipient displayed on the screen shown in FIG. 6 or in the area 602. When the screenshot save button 604 is selected, the screen shown in FIG. 6 or the image of the care recipient displayed in the area 602 is saved in the storage unit 402 of the smartphone 120. If there is something bothering the care recipient's complexion, display, etc., the caregiver selects the screenshot save button 604. When the image quality setting button 605 is selected, a screen for adjusting image quality is displayed. When the video save button 606 is selected, the video of the care recipient displayed in the area 602 and the audio between the care recipient and the caregiver A are saved in the storage unit 402. If there is something bothering the care recipient's complexion, display, content of the conversation, etc., the caregiver selects the video save button 606.

[0018] The record / play button 607 is selected when playing the video saved by the video save button 606. The add connection button 608 is selected when adding another person to the video call with the care recipient. For example, when the caregiver wants to consult with a colleague or a superior about the condition of the care recipient or the conversation with the care recipient, the caregiver selects the add connection button 608. When the add connection button 608 is selected, information of the smartphone 120 set as the smartphone 120 that can make a call with the communication device 110 is displayed together with information of the user of the smartphone 120. On this screen, the caregiver A selects a user to be added to the conversation with the care recipient. In the example of this embodiment, the explanation will be given assuming that the caregiver B, who is the user of the smartphone 120B, is selected. The caregiver B is an example of a second user. Note that here, when there are multiple smartphones 120 that can make a call with the information processing device 100 other than the smartphone 120A, the caregiver A may select multiple users to be added to the conversation with the care recipient.

[0019] 5, when a user to be added to the video call is selected, in sequence SQ506, the control unit 401 of the smartphone 120A transmits an additional connection request including identification information for identifying the smartphone 120 of the user selected as the user to be added to the information processing device 100. The identification information for identifying the smartphone 120 of the user included in the additional connection request is an example of destination information included in the additional connection request. Another example of destination information included in the additional connection request may be a telephone number of the smartphone 120 to be added. When the additional connection request is received, in sequence SQ507, the control unit 201 of the information processing device 100 transmits the additional connection request to the corresponding smartphone 120 (in the example of this embodiment, the smartphone 120B). The control unit 401 of the smartphone 120 that has received the additional connection request notifies the user of the incoming call by ringing or vibrating.

[0020] When the call is responded to, the control unit 401 of the smartphone 120B transmits a call response to the information processing device 100 in sequence SQ508. In sequence SQ509, the control unit 201 of the information processing device 100 adds the smartphone 120B to the connection between the communication device 110 and the smartphone 120A, making video calling possible. Sequence SQ509 in Fig. 5 indicates that a two-way call is possible between the communication device 110 and the smartphone 120B via the information processing device 100. Although omitted in Fig. 5 for the sake of simplicity of explanation, a call is also possible between the smartphone 120A and the smartphone 120B via the information processing device 100. The processing of sequences SQ506 to SQ509 is an example of processing for enabling communication between the care recipient, caregiver A, and caregiver B by connecting the communication device 110, caregiver A's smartphone 120, and caregiver B's smartphone 120 based on connection destination information included in an additional connection request when an additional connection request is received from caregiver A's smartphone 120A. Here, caregiver B is one of the multiple users set as call destinations of the communication device 110, other than caregiver A.

[0021] An example of a screen related to a video call displayed on smartphone 120A when smartphone 120B is further added is shown in Fig. 7. Fig. 7 is a diagram (part 2) showing an example of a screen related to a video call displayed on smartphone 120A. In the screen of Fig. 7, an image of the added user is displayed in area 701, compared to the screen of Fig. 6. In the screen of Fig. 7, for example, when video save button 606 is selected, a video of the care recipient displayed in area 602 and audio of the care recipient, caregiver A, and caregiver B are saved in memory unit 402.

[0022] According to this embodiment, when the care recipient and the caregiver, or the care recipient's family member, etc., are having a conversation, it is possible to immediately call another person and have a conversation together. Therefore, for example, even if the caregiver who first answers a video call with the person being cared for is inexperienced and wants to consult with another caregiver or have them check on the person's condition, the other caregiver can be immediately called to join the video call. Furthermore, since the communication device 110 can communicate with only a Wi-Fi router, there is no need to install a large-scale system, and the nursing care system 1000 can be constructed inexpensively and quickly.

[0023] (Variation 1) A modified example of the first embodiment will be described. FIG. 8 is a diagram showing an example of a system configuration of a care system 1000 of the first modified example. The care system 1000 of FIG. 8 includes a plurality of communication devices 110 compared to the care system 1000 of FIG. 1. The communication device 110A is a communication device installed at the bedside of a care recipient A. The communication device 110B is a communication device installed at the bedside of a care recipient B. In the first modified example, it is assumed that the smartphones 120A, 120B, and 120C are set as the smartphones 120 that can communicate with the communication device 110A. It is also assumed that the smartphones 120A, 120B, and 120C are set as the smartphones 120 that can communicate with the communication device 110B.

[0024] When the control unit 201 of the first modification receives a connection request based on the selection of the push button 115 of the communication device 110B while the communication device 110A and the smartphone 120A of the caregiver A are connected, the control unit 201 calls the smartphones 120 (smartphones 120B and 120B in the example of the first modification) other than the smartphone 120A of the caregiver A that is currently on a call, among the multiple smartphones set as smartphones 120 that can communicate with the communication device 110B. The communication device 110B is an example of a second terminal device.

[0025] According to the first modification, even if a plurality of communication devices 110 are installed in a facility or the like, the information processing device 100 can appropriately control connections and calls between the communication devices 110 and a plurality of smartphones.

[0026] (Variation 2) A modification of the first embodiment will be described. FIG. 9 is a diagram showing an example of a screen related to a video call displayed on the smartphone 120A of the second modification. When a predetermined keyword is used in a call between the care recipient and the caregiver A who is the operator of the smartphone 120A, the control unit 201 of the second modification controls the screen of the smartphone 120 of the caregiver A to display a message 901 corresponding to the predetermined keyword and a button 902 for sending a notification to a notification destination corresponding to the message on the screen of the smartphone 120 of the caregiver A. The button 902 is an example of a predetermined object. For example, when a predetermined keyword such as "the number of times of toileting is less than a predetermined number" or "convulsing" appears in a conversation between the care recipient and the caregiver, the control unit 201 controls the screen of the smartphone 120 to display a message 901 indicating that there is a possibility of heat stroke and a button 902. The control unit 201 may separate the care recipient and the caregiver based on the contents of the conversation, etc., and display an object corresponding to the predetermined keyword when the care recipient uses the predetermined keyword. When the control unit 201 determines that button 902 has been selected, it transmits information regarding the symptoms, etc. of the person being cared for to another information processing system with which it can communicate via the network (in the example of variant example 2, the system of an affiliated hospital or an emergency reporting system for a fire department, etc.) in accordance with the selected button 902.

[0027] According to the second modification, buttons and the like corresponding to the contents of the conversation can be displayed on the screen. When the button is selected, information about the user operating the communication device 110 can be transmitted to the system (or device) corresponding to the button. As another example, the control unit 201 may display a message or a button for sending a notification to a specified notification destination based on the speed of response to a call from the caregiver, rather than or in addition to the content of the conversation.

[0028] (Variation 3) A modification of the first embodiment will be described. When a predetermined keyword is mentioned in a conversation between the care recipient and the caregiver A, the control unit 201 of the third modification transmits information on the symptoms of the care recipient to another information processing system capable of communicating through a network corresponding to the predetermined keyword. For example, when a predetermined keyword such as "the number of times the care recipient goes to the toilet is less than a predetermined number of times" or "having convulsions" appears in a conversation between the care recipient and the caregiver, the control unit 201 transmits information on the symptoms of the care recipient to a system of an affiliated hospital or an emergency reporting system for a fire department or the like.

[0029] According to the third modification, information about the user operating the communication device 110 can be transmitted to the system (or device) in accordance with the contents of the conversation. As another example, the control unit 201 may transmit information about the person being cared for to another information processing system or another device based on the speed of response to the caregiver's call, rather than or in addition to the content of the conversation.

[0030] (Variation 4) A modified example of the first embodiment will be described. In the above-mentioned embodiment and the like, an example has been described in which a call is made from the communication device 110 to the smartphone 120. However, it is also possible for the smartphone 120 to call the communication device 110. When the control unit 201 receives a connection request to the communication device 110 from one of the smartphones 120 of multiple users, the control unit 201 connects the one smartphone 120 and the communication device 110, thereby enabling a call between the user of the one smartphone 120 and the care recipient.

[0031] According to the fourth modification, a call can be made from the smartphone 120 to the communication device 110 .
