  FIG. 7 is a flowchart showing an example of obstacle detection by the first information processing terminal according to the embodiment of the present invention. For example, in step S202, the first terminal detects an obstacle by the process shown in FIG.

(Example of setting an initial value for the transmission angle (step S301))
In step S301, the first terminal sets an initial value of the transmission angle. For example, the first terminal sets the initial value of the transmission angle to “0 °”.

(Example of ultrasonic wave transmission (step S302))
In step S302, the first terminal transmits an ultrasonic wave or the like in a direction corresponding to the transmission angle.

(Example of reception of ultrasonic waves, etc. (step S303))
In step S303, the first terminal receives the transmitted ultrasonic waves and the like.

(Storage example of detection result (step S304))
In step S304, the first terminal stores a detection result based on the reception result. For example, in step S304, the first terminal determines whether there is an obstacle based on whether the transmitted ultrasonic wave or the like has been received. Furthermore, when it is determined that there is an obstacle, the first terminal calculates the distance to the obstacle based on the time from transmission to reception. Next, the first terminal stores, as detection results, data indicating the presence or absence of an obstacle, and data indicating the distance to the obstacle, the direction in which the obstacle is, or the position of the obstacle based on the distance and direction, and the like. To do. That is, the first terminal generates “detection result data” (Table 2) based on a reception result such as an ultrasonic wave and stores it as a detection result.

(Example of determining whether or not detection has been performed for a predetermined direction (step S305))
In step S305, the first terminal determines whether detection has been performed for a predetermined direction. For example, when the first terminal performs detection in all directions, the first terminal performs steps S302 to S304 for each predetermined angle with respect to a transmission angle of “0 °” to “360 °”. Hereinafter, a case where the first terminal performs detection in all directions will be described as an example.

  When the first terminal detects all the transmission angles from “0 °” to “360 °” (YES in step S305), the first terminal ends the process. On the other hand, when the first terminal has not detected all the transmission angles from “0 °” to “360 °” (NO in step S305), the first terminal proceeds to step S306.

(Transmission angle change example (step S306))
In step S306, the first terminal changes the transmission angle. For example, the first terminal changes to a transmission angle obtained by adding “10 °” to the set transmission angle.

  The obstacle detection may be performed by radar other than ultrasonic waves, image processing, or a combination thereof according to the type of sensor of the first terminal.

  FIG. 8 is a diagram illustrating an example of a detection result according to an embodiment of the present invention. Specifically, FIG. 8 shows an example in which the first terminal T10 performs the process shown in FIG. 7 and detects obstacles around the caregiver C1 and the first terminal T10. As illustrated, FIG. 8 illustrates an example in which the first terminal T10 transmits ultrasonic waves in all directions, and the first terminal T10 detects an obstacle every “10 °”. That is, in FIG. 8, the first terminal T10 first sets “0 °” as an initial value to the transmission angle Ang, and adds “10 °” to each in step S306 (FIG. 7) to change the transmission angle. . Accordingly, in FIG. 8, the first terminal T10 performs steps S302 (FIG. 7) to S304 (FIG. 7) every “10 °”, and performs steps S302 to S304 for a total of 36 times.

  For example, in FIG. 8, the first terminal T10 includes the presence or absence of the wall 2, the direction according to the transmission angle Ang that detects the wall 2, the time from when the ultrasonic wave is transmitted until the ultrasonic wave reflected by the wall 2 is received, and the like. The distance to the wall 2 and the like based on is stored as a detection result.

  Therefore, the first terminal T10 detects obstacles around the first terminal T10 by the ultrasonic sensor TH20 (FIG. 2), and the presence / absence of the obstacle, the direction of the obstacle, and the distance of the obstacle. Etc. can be obtained.

(Data transmission example (step S203))
Returning to FIG. 6, in step S203, the first terminal transmits data to the second terminal and the third terminal, respectively. Specifically, in step S203, within the range set by the “range setting” shown in the above (Table 2), the first terminal transmits the data shown in the above (Table 3) to the second terminal and the third terminal. Each data signal is transmitted.

(Data reception example (step S204))
In step S204, the first terminal receives data from the second terminal and the third terminal, respectively. Specifically, in step S204, the data or data signal shown in the above (Table 4) transmitted by the second terminal and the third terminal, respectively, with respect to the data or data signal transmitted by the first terminal in step S203, respectively. Receive.

  That is, in step S203, the first terminal requests data such as “direction data” (Table 4) and “distance data” (Table 4) from the second terminal and the third terminal, respectively. On the other hand, when receiving the data or data signal transmitted in step S203, the second terminal and the third terminal include the “distance data” and the “direction data” in response to a request from the first terminal ( Data shown in Table 4) is transmitted to the first terminal.

(Position calculation example (step S205))
In step S205, the first terminal calculates the positions of the second terminal and the third terminal with respect to the first terminal based on the data shown in (Table 4) received in step S204.

  FIG. 9 is a diagram illustrating a calculation example of the position of the second information processing terminal with respect to the first information processing terminal according to an embodiment of the present invention. Specifically, as illustrated, an example in which the first terminal calculates the position P2 of the second terminal T20 with respect to the first terminal T10 will be described. In FIG. 9, it is assumed that the caregiver C1 having the first terminal T10 is stationary, whereas the care receiver CE1 having the second terminal T20 is positioned from the previous position P1 at a predetermined time. Suppose that it moves to P2. Further, the first terminal receives the data shown in the above (Table 4) from the second terminal T20 at the previous position P1 and position P2 in step S204 (FIG. 6), respectively.

  For example, the first terminal T10 calculates the position P2 based on the relative distance DIS of the second terminal T20 with respect to the first terminal T10 and the direction DIR toward the second terminal T20.

  Specifically, the first terminal T10 sets the relative distance DIS to a distance indicated by “distance data” (Table 4). The second terminal T20 transmits the data shown in (Table 3) to the first terminal T10, and the first terminal T10 calculates the relative distance DIS based on the “signal transmission level data” (Table 3). Good. For example, if BLE (Bluetooth (registered trademark) Low Energy) is used for data transmission / reception, the first terminal T10 calculates the relative distance DIS from the received signal strength of the advertising packet and the like.

  Further, the first terminal T10 calculates the direction DIR based on the respective “direction data” (Table 4) at the previous position P1 and position P2.

  Note that the first terminal T10 may further calculate the future position P3. Specifically, the first terminal T10 calculates the direction and speed toward which the care recipient CE1 heads based on the previous position P1, position P2, and the like. Next, the first terminal T10 estimates the future position P3, assuming that the care recipient CE1 moves in the same speed and the same direction for a predetermined time.

(Judgment example of whether or not the positions of all the second information processing terminals have been calculated (step S206))
Returning to FIG. 6, in step S206, the first terminal determines whether or not the positions of all the second information processing terminals have been calculated. Specifically, in the information processing system 1 (FIG. 1), the first terminal determines whether or not the positions of the second terminal and the third terminal are calculated in step S206. If it is determined that the positions of all the second information processing terminals have been calculated (YES in step S206), the first terminal proceeds to step S207. On the other hand, if it is determined that the positions of all the second information processing terminals have not been calculated (NO in step S206), the first terminal proceeds to step S204.

(Storage example of position (step S207))
In step S207, the first terminal stores the calculated positions of the second terminal and the third terminal with respect to the first terminal. For example, in step S207, the first terminal stores the calculation result of step S205 as “position data” of “first information processing terminal data” shown in (Table 2) above.

(Example of determination of destination (step S208))
In step S208, the first terminal determines the destination of the first terminal.

  FIG. 10 is a flowchart showing an example of determining the destination by the first information processing terminal according to the embodiment of the present invention.

(Example of calculation of position to be moved (step S401))
In step S401, the first terminal calculates the location of the movement destination.

  FIG. 11 is a diagram illustrating a calculation example of a position to be a movement destination by the first information processing terminal according to the embodiment of the present invention. Specifically, FIG. 11 shows an example of calculating the position of the destination P4. In FIG. 11, the distance between the position of the destination P4 and the position of the second terminal T20 is a distance D_T20, and the distance between the position of the destination P4 and the position of the third terminal T21 is a distance D_T21.

  In step S401 (FIG. 10), for example, the first terminal T10 calculates a position where the sum of the distance D_T20 and the distance D_T21 is minimum as the position of the movement destination P4. When the information processing system 1 has three or more second information processing terminals, the first terminal T10 calculates the position of the destination P4 from the sum of the three or more distances.

  Further, the position of the destination P4 is not limited to the position calculated based on the position of the second terminal T20 and the position of the third terminal T21.

  FIG. 12 is a diagram showing another calculation example of the position to be the movement destination by the first information processing terminal according to the embodiment of the present invention. Specifically, FIG. 12 shows an example where the cared person CE1 and the cared person CE2 move respectively. In this case, the distance D_T20 and the distance D_T21 are estimated positions such as the future position P3 (FIG. 9), positions where the cared person was present in the past, such as the previous position P1 (FIG. 9), or an average of these positions. It may be a moving average position.

  The destination P4 is a place where the distance between each second information processing terminal and the first information processing terminal becomes shorter on average. Therefore, when the caregiver C1 moves to the destination P4, the caregiver C1 can perform care or the like at a position where the distance to the care receiver CE1 and the care receiver CE2 is short. In addition, the caregiver C1 is likely to provide care, etc., if the distance to the care receiver CE1 and the care receiver CE2 is short, in many cases the prospect is good.

(Detection result acquisition example (step S402))
Returning to FIG. 10, in step S402, the first terminal obtains the obstacle detection result in step S202 (FIG. 6).

(Example of determining whether there is an obstacle between the second information processing terminal (step S403))
In step S403, the first terminal determines whether there is an obstacle between the first terminal and the second or third terminal based on the detection result or the like.

  Specifically, if there is an obstacle between the first terminal and the second terminal or between the first terminal and the third terminal (YES in step S403), the first terminal goes to step S404. move on. On the other hand, if there is no obstacle between the first terminal and the second terminal and between the first terminal and the third terminal (NO in step S403), the first terminal proceeds to step S407.

(Judgment example of whether or not there is an obstacle for all the second information processing terminals (step S404))
In step S404, the first terminal determines whether or not the determination as to whether there is an obstacle has been made for all the second information processing terminals.

  Specifically, when the first terminal determines whether there is an obstacle for the second terminal and the third terminal (YES in step S404), the first terminal proceeds to step S406. On the other hand, if the first terminal has not determined whether there is an obstacle with respect to either the second terminal or the third terminal (NO in step S404), the first terminal proceeds to step S405.

(Example of moving destination change (step S405))
In step S405, the first terminal changes the position of the movement destination.

  FIG. 13 is a diagram showing an example of changing the destination by the first information processing terminal according to the embodiment of the present invention. Specifically, FIG. 13 is an example in which the position of the destination P4 is calculated in step S401 (FIG. 10). In FIG. 13, it is assumed that there is a wall 2 between the destination P4 and the second terminal T20.

  In FIG. 13, the first terminal T10 changes the destination P4 to the changed destination P5. Note that the position of the destination P5 after the change is an example of a position where the second information processing terminal without any obstacle such as the wall 2 can be seen between the second terminal T20 and the third terminal T21. For this reason, when the caregiver C1 moves to the position of the destination P5 after the change, the caregiver C1 has a good outlook for both the care receiver CE1 and the care receiver CE2. Therefore, when the first terminal T10 changes the destination P4 to the destination P5 after the change, the caregiver C1 is a position where the caregiver CE1 and the care recipient CE2 are more likely to perform care etc. Nursing care or the like can be performed at the position of the destination P5.

(Example of outputting output data to the second information processing terminal (step S406))
Returning to FIG. 10, in step S406, the first terminal causes the second terminal, the third terminal, or the second terminal and the third terminal to output output data.

  FIG. 14 is a diagram illustrating an output example of output data by the second information processing terminal according to the embodiment of the present invention. Specifically, FIG. 14 is an example in which the same wall 2 as in FIG. 13 is located around the first terminal T10. For example, if the cared person CE1 is at the position illustrated in FIG. 14, even if the caregiver C1 moves to the position of the movement destination P4 illustrated in FIG. In addition, there is a wall 2 between the second terminal T20.

  Thus, even when the caregiver C1 moves to the position of the destination P4 or the destination P5 after the change, etc., there is a wall 2 between the first information processing terminal and any one of the second information processing terminals. There is. In this case, the first terminal T10 may cause the second terminal T20 to output output data for moving the care receiver CE1 to the point P6, for example (step S406 (FIG. 10)).

  Specifically, in step S406, the first terminal T10 transmits output command data, data indicating the position of the first terminal T10, and the like to the second terminal T20. Next, the 1st terminal T10 makes the 2nd terminal T20 calculate the direction etc. which the caregiver C1 approaches the position where the caregiver C1 has a good line of sight, or the position where the 1st terminal T10 exists from the position where the 1st terminal T10 exists. For example, it is assumed that the direction toward the point P6 and the distance to the point P6 are calculated by the second terminal T20. It is desirable that the point P6 is calculated so as to be a position within the range R set by “range setting” (Table 2).

  Subsequently, the first terminal T10 generates output data for moving the care receiver CE1 to the point P6 in the second terminal T20. For example, the output data is voice data indicating the direction of the point P6, image data such as an arrow or a map indicating the direction of the point P6, voice data indicating the distance to the point P6, character data indicating the distance to the point P6, or This is a combination of these data. Next, based on the output data, the first terminal T10 outputs to the second terminal T20 output such as display or audio output by the audio output unit TH10 (FIG. 2), the display TH16 (FIG. 2), or a combination thereof. To do. In addition, the output may be performed when the care recipient comes out of the range R.

(Judgment example of whether or not all second information processing terminals have been checked (step S407))
Returning to FIG. 10, in step S407, the first terminal determines whether all the second information processing terminals have been checked. That is, in step S407, the first terminal determines whether step S403 and the like have been performed for the second terminal and the third terminal, respectively.

  When determining that all the second information processing terminals have been checked (YES in step S407), the first terminal ends the process. On the other hand, when determining that all the second information processing terminals have not been checked (NO in step S407), the first terminal proceeds to step S403.

(Storage example of destination, etc. (step S209))
Returning to FIG. 6, in step S209, the first terminal stores the destination and the like. Specifically, in step S209, the first terminal stores data indicating the movement destination determined in step S208. As shown in FIG. 14, when the care receiver CE1 is moved by causing the second terminal to output, the first terminal is the second terminal, the third terminal, or the second terminal and the third terminal. Output data or the like may be obtained from the above. Next, the first terminal may store the acquired output data and the like as “position data” (Table 2) of “first information processing terminal data”.

(Example of destination notification (step S210))
In step S210, the first terminal notifies the destination. Specifically, the first terminal generates “notification data” (Table 2) based on the data indicating the movement destination stored in step S209. For example, “notification data” is data that displays or outputs the direction, distance, or a combination of the destination by the voice output unit TH10 (FIG. 2), the display TH16 (FIG. 2), or a combination thereof. It is.

(Example of waiting for a predetermined time (step S211))
In step S211, the first terminal stands by for a predetermined time. That is, in step S211, the first terminal waits for a predetermined time so that the processing shown in FIG. 6 is performed periodically.

(Setting example of second information processing terminal)
FIG. 15 is a flowchart showing an example of settings for the second information processing terminal according to the embodiment of the present invention. For example, the setting shown in FIG. 15 is performed when the power of either the second terminal or the third terminal is turned on. Hereinafter, an example of the second terminal will be described.

(Input example of device ID (step S501))
In step S501, the second terminal inputs a device ID. Specifically, in step S501, the second terminal inputs device IDs such as “own device ID data” and “first information processing terminal ID data” shown in Table 1 above.

(Example of overall processing of second information processing terminal)
FIG. 16 is a flowchart showing an example of overall processing by the second information processing terminal according to the embodiment of the present invention. Specifically, the process illustrated in FIG. 16 is a process performed by the second terminal and the third terminal, respectively, after the setting illustrated in FIG. 15 is performed. Hereinafter, an example performed by the second terminal will be described.

(Judgment example of whether an output command data signal has been received or a request signal has been received (step S601))
In step S601, the second terminal determines whether it has received an output command data signal or a request signal. Specifically, when output command data is transmitted from the first terminal to the second terminal in step S406 shown in FIG. 10, the second terminal determines that the output command data signal has been received. On the other hand, when the data or data signal shown in the above (Table 3) is transmitted from the first terminal to the second terminal in step S203 shown in FIG. 6, the second terminal determines that the request signal has been received.

  If it is determined that the second terminal has received the output command data signal (“output command data signal” in step S601), the second terminal proceeds to step S602. On the other hand, if it is determined that the second terminal has received the request signal (“request signal” in step S601), the second terminal proceeds to step S603.

(Example of output based on output data (step S602))
In step S602, the second terminal performs output based on the output data. Specifically, in step S602, the second terminal generates output data and performs output based on the output data as in the process shown in FIG.

(Example of generating direction data and distance data (step S603))
In step S603, the second terminal generates “direction data” (Table 4) and “distance data” (Table 4). Specifically, in step S603, the second terminal calculates the distance to the first terminal as “distance data” based on the received request signal and the received data (Table 3). For example, the second terminal compares the field strength of the received request signal with the “signal transmission level data” included in the data in (Table 3), and calculates the attenuation factor of the field strength. Next, the second terminal calculates the distance from the first terminal based on the calculated attenuation rate of the electric field strength and the like.

  Also, as shown in FIG. 9, the second terminal calculates the direction toward the second terminal as “direction data” based on the previous position P1, position P2, and the like. The “direction data” may be obtained by the acceleration / direction sensor TH06 (FIG. 2) or the like.

  Further, the second terminal may transmit data indicating the electric field strength of the received request signal, data indicating the previous position P1 and position P2, and the like to the first terminal. In this case, the first terminal calculates the distance between the first terminal and the second terminal and the direction of movement of the second terminal based on the data received from the second terminal.

(Example of storing direction data and distance data (step S604))
In step S604, the second terminal stores “direction data” and “distance data”.

(Example of transmission of direction data, distance data, etc. (step S605))
In step S605, the second terminal transmits “direction data”, “distance data”, and the like to the first terminal. For example, in step S605, the second terminal transmits the data or data signal shown in (Table 4) above to the first terminal.

  FIG. 16 shows an example in which the second terminal transmits direction data and distance data in response to the request signal from the first terminal. However, the second terminal periodically sends the direction data and the distance data to the first terminal. Distance data or the like may be transmitted. For example, even if there is no request signal from the first terminal, the second terminal performs steps S603 to S605 every predetermined time set in advance, and receives the data or data signal shown in the above (Table 4) as the first You may transmit to a terminal.

  In the information processing system, a first terminal that is an example of a first information processing terminal requests direction data and distance data from a second terminal and a third terminal that are examples of a second information processing terminal, respectively. Next, the second terminal and the third terminal transmit the direction data and the distance data to the first terminal in response to the request from the first terminal.

  In addition, since the direction data indicates directions in which the second terminal and the third terminal move, the first terminal can specify directions in which the second terminal and the third terminal move, respectively. Further, since the distance data indicates the relative distance between the first terminal and the second terminal and the relative distance between the first terminal and the third terminal, respectively, the first terminal is the distance between the second terminal and the third terminal. Each distance can be specified.

  Therefore, based on the direction data and the distance data, the first terminal can calculate the positions of the second terminal and the third terminal, respectively. Therefore, the 1st terminal can determine the position which is easy to perform care etc. with which the sum total of relative distance with each 2nd information processing terminal becomes the minimum based on the position etc. of the 2nd terminal and the 3rd terminal.

(Second Embodiment)
(Overall configuration example)
FIG. 17 is an overall configuration diagram illustrating an example of an overall configuration of an information processing system according to an embodiment of the second embodiment of the present invention. Specifically, in the second embodiment, for example, an information processing system 1A is used.

  In the second embodiment, a plurality of caregivers perform care for each of a plurality of care recipients. Hereinafter, as shown in FIG. 17, an example will be described in which there are two caregivers, and each caregiver provides care to two care recipients. Specifically, in FIG. 17, it is assumed that the care giver C1 has the first terminal T10 and cares for the care receiver CE1 and the care receiver CE2.

  Further, in FIG. 17, the caregiver C2 has a fourth terminal T30, which is an example of a third information processing terminal, and performs care for the care receiver CE3 and the care receiver CE4. Further, it is assumed that the care receiver CE1 has a second terminal T20, and the care receiver CE2 has a third terminal T21. Furthermore, it is assumed that the cared person CE3 has a fifth terminal T22 and the cared person CE4 has a sixth terminal T23. That is, a plurality of caregivers each have a first information processing terminal or a third information processing terminal, and a plurality of care recipients each have a second information processing terminal. Note that the information processing system 1A may further include a first information processing terminal, a second information processing terminal, or a third information processing terminal.

  Further, the first terminal T10, the second terminal T20, the third terminal T21, the fourth terminal T30, the fifth terminal T22, and the sixth terminal T23 have, for example, the hardware configuration shown in FIG. Therefore, description of the hardware configuration of each information processing terminal is omitted.

  For example, the fourth terminal T30 performs the overall processing illustrated in FIG. 6 on the fifth terminal T22 and the sixth terminal T23. Further, the fourth terminal T30 performs the entire process shown in FIG. 16 on the first terminal T10. Furthermore, the fourth terminal T30 performs the settings shown in FIGS.

(Processing example of first information processing terminal and third information processing terminal)
FIG. 18 is a diagram illustrating an example of processing performed by the first information processing terminal and the third information processing terminal according to an embodiment of the second embodiment of the present invention. Specifically, FIG. 18 is an example of notifying each caregiver of the destination based on the “setting range” (Table 2) of each of the first terminal T10 and the fourth terminal T30.

  A “setting range” is set in each of the first terminal T10 and the fourth terminal T30 in step S103 (FIG. 5) or the like. For example, the first range R1 in which the caregiver C1 can perform nursing care or the like is set as the “setting range” in the first terminal T10, and similarly, the second range R2 in which the caregiver C2 can perform nursing care or the like in the fourth terminal T30. Is set as the “setting range”.

  Next, as illustrated, the first terminal T10 and the fourth terminal T30 each determine a destination so that the overlapping range of the first range R1 and the second range R2 is reduced. For example, the first terminal T10 or the fourth terminal T30 calculates the distance between the first terminal T10 and the fourth terminal T30. Next, as illustrated, the first terminal T10 and the fourth terminal T30 each determine a destination so that the first range R1 and the second range R2 circumscribe each other.

  When the overlapping range of the first range R1 and the second range R2 decreases, the range in which care can be performed by the caregiver C1 and the caregiver C2 can be widened. Therefore, in the information processing system 1A, each caregiver's destination is determined so that overlapping of ranges related to the “setting range” set in each of the first information processing terminal and the third information processing terminal is reduced. Therefore, the information processing system 1A can widen the range in which care can be performed by a plurality of caregivers.

(Another processing example of the first information processing terminal)
FIG. 19 is a diagram illustrating an example of another process performed by the first information processing terminal and the third information processing terminal according to an embodiment of the second embodiment of the present invention. Specifically, in the second embodiment, the first information processing terminal and the third information processing terminal respectively change the “second information processing terminal ID data” shown in (Table 1). For example, the information processing system 1A deletes the device ID of the fifth terminal T22 input to the “second information processing terminal ID data” of the fourth terminal T30, and the “second information processing terminal ID data of the first terminal T10”. To add the device ID of the fifth terminal T22.

  FIG. 20 is a diagram illustrating an example of a processing result of another process performed by the first information processing terminal and the third information processing terminal according to an embodiment of the second embodiment of the present invention. For example, as illustrated, an example will be described in which a cared person CE3 moves among a plurality of cared persons, the cared person CE3 moves out of the second range R2, and further moves into the range of the first range R1. In this case, since the cared person CE3 moves to a position outside the second range R2, the carer C2 often has difficulty in performing care or the like on the cared person CE3. On the other hand, since the cared person CE3 moves into the range of the first range R1, the carer C1 can easily perform care for the cared person CE3.

  In step S401 (FIG. 10), the fourth terminal T30 may calculate a moving destination where the caregiver C2 approaches the care receiver CE3 based on the direction data and distance data of the fifth terminal T22. For this reason, when the caregiver C2 moves to a destination that approaches the care recipient CE3, a movement work load may occur in the caregiver C2. Further, when the care giver C2 moves to a destination that approaches the care receiver CE3, the care receiver CE4 may be out of the second range R2, and the caregiver C2 may have difficulty in performing care for the care receiver CE4.

  On the other hand, when the “second information processing terminal ID data” of each of the first terminal T10 and the fourth terminal T30 is changed by the process shown in FIG. 19, the caregiver C2 takes care of the fourth terminal T30. It is possible to calculate a moving destination where caregiver or the like can be easily performed on the person CE4. In addition, the first terminal T10 can calculate a destination where the caregiver C1 can easily perform care etc. for the care receiver CE1, the care receiver CE2, and the care receiver CE3. Therefore, the information processing system 1A can determine positions where the caregiver C1 and the caregiver C2 can easily perform care or the like. That is, the information processing system 1 </ b> A can determine a position where the user who performs monitoring can easily monitor the target.

  Note that all or part of each processing according to the present invention is executed by a computer described in a legacy programming language or an object-oriented programming language such as an assembler, C, C ++, C #, and Java (registered trademark). It may be realized by the program. That is, the program is a computer program for causing a computer such as an information processing terminal, an information processing apparatus, or an information processing system including the information processing apparatus to execute each process.

  The program can be stored and distributed in a computer-readable recording medium such as ROM or EEPROM (Electrically Erasable Programmable ROM).
