Fig. 4 is a diagram showing a second embodiment of the functional configuration of an information processing system of the present invention.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] FIG. 1 is a diagram showing an example of the external configuration of an information processing system according to an embodiment of the present invention.

[0012] In one embodiment of the information processing system of the present invention, an acceleration sensor 2, a temperature sensor 3, a GPS sensor 4, and other sensors 5 that operate on vibration power generation are embedded in a smartphone cover 6, as shown in the example of FIG. 1 , or in a sticker (not shown in FIG. 1 ). When the user terminal 2 falls with the smartphone cover 6 or sticker attached to the user terminal 1, the acceleration sensor 2 detects the fall of the user terminal 1, communicates wirelessly with the user terminal 2 via Bluetooth (registered trademark) or the like, and notifies the user terminal 2 of the fall detection. When an abnormal temperature condition (so-called smartphone heatstroke, smartphone hypothermia, etc.) occurs in the user terminal 2 with the smartphone cover 6 or sticker attached to the user terminal 1, the temperature sensor 3 detects the abnormal temperature condition of the user terminal 1, communicates wirelessly with the user terminal 2 via Bluetooth (registered trademark) or the like, and notifies the user terminal 2 of the abnormal temperature condition. If the user terminal 2 becomes lost while the smartphone cover 6 or sticker is attached to the user terminal 1, the GPS sensor 4 detects that the user terminal 2 is lost from the current location of the user terminal 1, and communicates wirelessly with the user terminal 2 via Bluetooth (registered trademark) or the like to notify the user terminal 2 of the lost state. If the user terminal 2 enters a predetermined state while the smartphone cover 6 or sticker is attached to the user terminal 1, the other sensor 5 detects that the predetermined state has occurred, and communicates wirelessly with the user terminal 2 via Bluetooth (registered trademark) or the like to notify the user terminal 2 of the predetermined state. The user terminal 1 manages various states such as the notified fall detection and notifies (notifies) the user.

[0013] In this embodiment, management of various notified conditions such as fall detection and notification (notification) to the user are provided as functions of dedicated application software (hereinafter referred to as the "dedicated app") that enables use of this service and is installed in the user terminal 1. However, this function may also be exercised by accessing a dedicated website (hereinafter referred to as the "dedicated site") displayed by the browser function of the user terminal 1.

[0014] FIG. 2 is a block diagram showing an example of the hardware configuration of a user terminal in the information processing system shown in FIG.

[0015] The user terminal 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an input unit 16, an output unit 17, a memory unit 18, a communication unit 19, and a drive 20.

[0016] The CPU 11 executes various processes according to programs recorded in the ROM 12 or programs loaded from the storage unit 18 into the RAM 13. The RAM 13 also stores data and the like necessary for the CPU 11 to execute various processes.

[0017] The CPU 11, ROM 12, and RAM 13 are interconnected via a bus 14. An input / output interface 15 is also connected to this bus 14. An input unit 16, an output unit 17, a storage unit 18, a communication unit 19, and a drive 20 are connected to the input / output interface 15.

[0018] The input unit 16 is configured with, for example, a keyboard and is used to input various types of information. The output unit 17 is configured with a display such as a liquid crystal display, a speaker, and the like and outputs various types of information as images and sounds. The storage unit 18 is configured with a DRAM (Dynamic Random Access Memory) and the like and stores various types of data. The communication unit 19 performs wireless communication with the acceleration sensor 2, temperature sensor 3, GPS sensor 4, other sensors 5, and the like via Bluetooth (registered trademark) and also performs communication with other devices (not shown) via the Internet, etc.

[0019] Removable media 31, such as a magnetic disk, optical disk, magneto-optical disk, or semiconductor memory, is appropriately attached to the drive 20. Programs read from the removable media 31 by the drive 20 are installed in the storage unit 18 as needed. The removable media 31 can also store various data stored in the storage unit 18 in the same way as the storage unit 18.

[0020] Various processes can be executed by cooperation between various hardware and various software that constitute the information processing system of FIG. 1, including the information processing device 1 of FIG. 2 and the acceleration sensor 2, temperature sensor 3, GPS sensor 4, and other sensors 5 of FIG. 1.

[0021] FIG. 3 is a functional block diagram showing an example of the functional configuration of the user terminal of FIG. 2 in the information processing system of FIG.

[0022] An acceleration sensor 2 that operates by vibration power generation, a temperature sensor 3, a GPS sensor 4, and other sensors 5 are arranged on a member (for example, a smartphone cover 6 in the example of FIG. 1 ) that can be attached to a user terminal 1 carried by a user. When such a member is attached to the user terminal 1, a status detection unit 51, a status management unit 52, and a status presentation unit 53 function in the CPU 11 of the user terminal 1. A terminal status DB 61 and a user DB 62 are provided in one area of ​​the memory unit 18.

[0023] A dedicated application that causes the status detection unit 51, the status management unit 52, and the status presentation unit 53 to function on the user terminal 1 is installed on the user terminal 1.

[0024] The state detection unit 51 receives the detection results of the acceleration sensor 2, temperature sensor 3, GPS sensor 4, and other sensors 5 via a predetermined wireless method (Bluetooth (registered trademark) in this embodiment) when a component (smartphone cover 6 in the example of Figure 1) is attached, and detects various states of the user terminal 1 based on the detection results.

[0025] For example, the state detection unit 51 receives the detection result of the acceleration sensor 2 via a predetermined wireless method (Bluetooth (registered trademark) in this embodiment) when a member (smartphone cover 6 in the example of FIG. 1 ) is attached, and detects that the user terminal 1 has fallen based on the detection result. Also, for example, the state detection unit 51 receives the detection result of the temperature sensor 3 via a predetermined wireless method (Bluetooth (registered trademark) in this embodiment) when a member (smartphone cover 6 in the example of FIG. 1 ) is attached, and detects an abnormal state related to the temperature of the user terminal 1 (so-called smartphone heatstroke, smartphone hypothermia, etc.) based on the detection result. Also, for example, the state detection unit 51 receives the detection result of the GPS sensor 4 via a predetermined wireless method (Bluetooth (registered trademark) in this embodiment) when a member (smartphone cover 6 in the example of FIG. 1 ) is attached, and detects that the user terminal 1 has been lost based on the detection result. For example, when a component (in the example of Figure 1, the smartphone cover 6) is attached, the state detection unit 51 receives the detection results of the other sensors 5 via a predetermined wireless method (in this embodiment, Bluetooth (registered trademark)), and detects a predetermined state of the user terminal 1 based on the detection results.

[0026] The status management unit 52 manages various statuses of the user terminal 1, including a drop of the user terminal 1 detected by the status detection unit 51, an abnormal status related to temperature (so-called smartphone heatstroke, smartphone low temperature syndrome, etc.), a lost status, etc., by storing the statuses in a terminal status DB 61. The status presentation unit 53 presents various statuses of the user terminal 1, including an abnormal status related to the drop temperature of the user terminal 1 detected by the status detection unit 51 (so-called smartphone heatstroke, smartphone low temperature syndrome, etc.), a lost status, etc., to the user by outputting the statuses from the output unit 17. Of the content presented to the user, information related to the user is stored in the user DB 62.

[0027] A dedicated application that causes the user terminal 1 to function as a state detection unit 51, a state management unit 52, and a state presentation unit 53 is installed in the user terminal 1.

[0028] Next, a second embodiment of the information processing system according to the present invention will be described with reference to FIG. 4. FIG. 4 is a diagram showing the functional configuration of a second embodiment of the information processing system according to the present invention. In describing the second embodiment, the same components as those in FIG. 3 are designated by the same reference numerals, and their description will be omitted. In the above embodiment, the smartphone cover 6 was described as an example of a component (device) that detects the state of the terminal based on information acquired from the user terminal 1 and makes suggestions to the user. However, as shown in FIG. 4, this second embodiment includes an IoT terminal 100 (dedicated terminal) and another device 120.

[0029] The IOT terminal 100 includes multiple sensors (such as the acceleration sensor 2, temperature sensor 3, GPS sensor 4, and other sensors 5) shown in FIG. 1 and is used in close proximity to the user terminal 1. If the sensors are capable of wireless detection, the IOT terminal 100 may be placed away from the user terminal 1. The other sensors 5 include, for example, sensors that detect the charge level of the user terminal 1 or the moisture content of the user terminal 1 through communication with the user terminal 1. In other words, the IOT terminal 100 is a dedicated terminal that can be attached and detached to the user terminal 1 in which the acceleration sensor 2, temperature sensor 3, GPS sensor 4, and other sensors 5 are arranged.

[0030] The IOT terminal 100 includes a control device 110. An acceleration sensor 2, a temperature sensor 3, a GPS sensor 4, and other sensors 5 are connected to the control device 110. The control device 110 includes the same hardware as the user terminal 1 shown in FIG. 2. To distinguish it from the hardware configuration of the user terminal 1, the hardware configuration of the control device 110 will be referred to as a CPU 11S, a communication unit 19S, etc., hereinafter, and the hardware configuration of the user terminal 1 will be denoted with a U after the reference numeral. Specifically, the hardware configuration will be referred to as a CPU 11U, a communication unit 19U, a memory unit 18U, etc.

[0031] The CPU 11S of the control device 110 functions as a communication control unit 111 when executing processing on the IOT terminal 100. The communication control unit 111 executes control to transmit detection results detected by each of the multiple sensors 2 to 5 via Bluetooth communication with the user terminal 1 to the other device 120, for example, via Bluetooth (a specified wireless method). The other device 120 is, for example, an information processing device such as a server provided by a specified service provider. The server has a hardware configuration similar to that of the user terminal 1 shown in FIG. 2. Note that the wireless method for communication with the other device 120 may be Bluetooth or data communication using, for example, a wireless LAN or a mobile phone network (e.g., 4G or 5G communication), as long as it is a specified wireless method. That is, the communication control unit 111 executes control to transmit detection results of each of the multiple sensors (e.g., the acceleration sensor 2, the temperature sensor 3, the GPS sensor 4, the other sensor 5, etc.) to the other device 120 other than the user terminal 1, via a specified wireless method or another method.

[0032] The communication control unit 111 acquires the current remaining charge level through periodic communication with the user terminal 1 (for example, wireless communication at intervals of 5 or 10 minutes), and also acquires the current state of the user terminal 1 from detection results of various sensors and transmits the information to the other device 120. The remaining charge level may be acquired through wireless communication, or may be acquired using a detection function previously provided in the user terminal 1 and transmitted to the other device 120.

[0033] In the other device 120, for example, if the detection result of the acceleration sensor 2 is XX m / s^2, if the detection result of the temperature sensor 3 is YY degrees, if the detection result of the GPS sensor 4 is the current location (latitude, longitude) of the user terminal 1, if the detection result of the other sensor 5 is, for example, the remaining charge, ZZ%, etc. are acquired. If the detection result of the other sensor 5 is, for example, the moisture content (amount of water vapor), the moisture content WWg, etc. are acquired. The remaining charge and moisture content (amount of water vapor) may be acquired from the user terminal 1 by communication with the user terminal 1, rather than from the other sensor 5.

[0034] The other device 120 notifies the user terminal 1 of the status (e.g., outputs an alert including a recommendation) based on the detection results of the sensors received through the IOT terminal 100. The notification destination may be the user terminal 1, a terminal of the service provider that provides the IOT terminal 100, or another device. Specifically, the other device 120 compares the detected value with a preset threshold or range value, and outputs an alert if the detected value deviates from the threshold or is outside the range. If the temperature value detected by the temperature sensor 3 reaches a range value, for example, below 0 degrees or above 35 degrees, the other device 120 outputs an abnormality alert to the user terminal 1. If the amount of water vapor detected by the moisture sensor 3 exceeds the threshold, the other device 1 outputs an abnormality alert to the user terminal 1. If the acceleration detected by the acceleration sensor 2 exceeds the threshold, the other device 1 outputs an abnormality alert to the user terminal 1. Furthermore, if the acceleration detected this time exceeds the threshold by a value greater than the acceleration detected last time, a malfunction is suspected, and the other device 1 outputs an alert including a replacement suggestion (recommendation) to the user terminal 1. Note that, instead of predetermining thresholds for the detection results of each sensor, a maintenance standard may be used in conjunction with the detection results of each sensor, and an alert may be issued based on the comparison with the maintenance standard. Furthermore, when a user loses the user terminal 1, the detection results of the GPS sensor 4 (location information of the user terminal 1) can be read by issuing a read instruction from a specific terminal to the other device 120, and the location information of the user terminal 1 is used when searching for the user terminal 1. Furthermore, in the above-described embodiment, an alert is output based on the detection results of each sensor, but the detection results of each sensor may be combined to determine the state of the user terminal 1, and an alert may be output based on the determination result.

[0035] Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within the scope of achieving the object of the present invention are considered to be included in the present invention.

[0036] For example, in the example of FIG. 1 , the acceleration sensor 2 that detects the fall of the user terminal 1 is attached to the smartphone cover 6, but this is not limited thereto. It can be attached to any component that can be attached to the user terminal 1 carried by the user (e.g., the smartphone cover 6 in the example of FIG. 1 , or the IoT terminal 100 in the example of FIG. 4 ), and can be embedded in a sticker, as described above. Also, for example, the communication method between the acceleration sensor 2, temperature sensor 3, GPS sensor 4, and other sensors 5 and the user terminal 1 is Bluetooth (registered trademark) in the above-described embodiment, but this is not limited thereto and any wireless communication method can be used. Furthermore, in the above-described embodiment, the GPS sensor 4 is used as the sensor for detecting the position of the user terminal 1, but this is not limited thereto. Any sensor that can directly or indirectly detect the position of the user terminal 1 will suffice.

[0037] The external configuration shown in FIG. 1 and the hardware configuration shown in FIG. 2 are merely examples for achieving the object of the present invention, and are not particularly limited.

[0038] Furthermore, the functional block diagram shown in Fig. 3 is merely an example and is not particularly limited. That is, it is sufficient if the information processing system in Fig. 1 is provided with the functions capable of executing the various processes described above as a whole, and the functional blocks and databases used to realize these functions are not particularly limited to the example in Fig. 3.

[0039] Furthermore, the locations of the functional blocks and databases are not limited to those shown in Fig. 3 and may be arbitrary. For example, at least some of the functional blocks and databases arranged on the user terminal 1 side may be provided in another information processing device.

[0040] The above-described series of processes can be executed by hardware or software, and each functional block can be configured by hardware alone, software alone, or a combination of both.

[0041] When a series of processes is executed by software, the programs constituting the software are installed onto a computer or the like from a network or a recording medium. The computer may be a computer incorporated into dedicated hardware. The computer may also be a computer capable of executing various functions by installing various programs, such as a server, a general-purpose smartphone, or a personal computer.

[0042] The recording medium containing such a program may be composed not only of a removable medium (not shown) that is distributed separately from the device main body in order to provide the program to the user, but also of a recording medium that is provided to the user in a state that is pre-installed in the device main body.

[0043] In this specification, the steps describing the program to be recorded on the recording medium include not only processes that are performed in chronological order, but also processes that are not necessarily performed in chronological order but are performed in parallel or individually.

[0044] To sum up, the information processing system to which the present invention is applied is sufficient as long as it has the following configuration, and can take on a variety of different embodiments. That is, an information processing system to which the present invention is applied (for example, the information processing system of FIG. 1 ) is an information processing system including: a mobile terminal carried by a user (for example, the user terminal 1 of FIGS. 1 to 4 ); and a sensor (for example, the acceleration sensor 2, temperature sensor 3, GPS sensor 4, or other sensor 5 of FIGS. 1 , 3, and 4 ) that detects a predetermined physical quantity and is disposed on a member that can be attached to the mobile terminal (for example, the smartphone cover 6 of FIG. 1 or a sticker not shown), and the information processing system is provided with: a drop detection means (for example, the state detection unit 51 of FIGS. 3 and 4 ) that receives the detection results of the sensor by a predetermined wireless method (for example, Bluetooth (registered trademark)) when the member is attached, and detects the state of the mobile terminal based on the detection results; a state management means (for example, the state management unit 52 of FIGS. 3 and 4 ) that manages the state of the mobile terminal, including the detection results of the drop detection means; and a state presentation means (for example, the state presentation unit 53 of FIGS. 3 and 4 ) that presents the state of the mobile terminal, including the detection results of the drop detection means, to the user.

[0045] This makes it possible to realize a simple method for detecting the state of a mobile terminal (portable terminal), such as detecting a fall.

[0046] The sensor is an acceleration sensor (e.g., acceleration sensor 3 in Figures 1 and 4) that operates by vibration power generation, and the state detection means (e.g., state detection unit 51 in Figures 3 and 4) can detect, as the detection result, that the mobile terminal (e.g., user terminal 1 in Figures 1 to 4) has fallen.

[0047] The sensor may be a temperature sensor (e.g., temperature sensor 3 in Figures 1 and 4), and the state detection means (e.g., state detection unit 51 in Figures 3 and 4) may detect an abnormal state related to the temperature of the mobile terminal (e.g., user terminal 1 in Figures 1 to 4) as the detection result.

[0048] The sensor may be a position detection sensor (e.g., the GPS sensor 4 in Figures 1 and 4), and the status detection means (e.g., the status detection unit 51 in Figures 3 and 4) may detect, as the detection result, a lost status of the mobile terminal (e.g., the user terminal 1 in Figures 1 to 4).

[0049] The mobile terminal (e.g., the user terminal 1 in Figures 1 to 4) may have application software (e.g., the dedicated application described above) installed therein that causes the status detection means, the status management means, and the status presentation means to function on the mobile terminal (e.g., the user terminal 1 in Figures 1 to 4).

[0050] The mobile terminal (e.g., user terminal 1 in FIG. 4) may further include a dedicated terminal (e.g., IOT terminal 100 in FIG. 4) that is detachable from the mobile terminal (e.g., user terminal 1 in FIG. 4) and that has a plurality of the sensors arranged thereon, and the dedicated terminal (e.g., IOT terminal 100 in FIG. 4) may have a communication control means (e.g., communication control unit 111 in FIG. 4) that executes control to transmit the detection results of each of the plurality of sensors (e.g., acceleration sensor 2, temperature sensor 3, GPS sensor 4, and other sensor 5 in FIGS. 1, 3, and 4) to the mobile terminal (e.g., user terminal 1 in FIG. 4) by the specified wireless method (e.g., Bluetooth (registered trademark)).

[0051] The communication control means (e.g., communication control unit 111 in FIG. 4) of the dedicated terminal (e.g., IoT terminal 100 in FIG. 4) further executes control to transmit the detection results of each of the plurality of sensors (e.g., acceleration sensor 2, temperature sensor 3, GPS sensor 4, and other sensors 5 in FIG. 4) to another device (e.g., other device 120 in FIG. 4) different from the mobile terminal (e.g., user terminal 1 in FIG. 4) by the predetermined wireless method (e.g., Bluetooth (registered trademark)) or another method (e.g., wireless LAN (registered trademark)). This allows another device (e.g., other device 120 in FIG. 4) different from the mobile terminal (e.g., user terminal 1 in FIG. 4) to check the status of the mobile terminal (e.g., user terminal 1 in FIG. 4) and take action against the mobile terminal (e.g., user terminal 1 in FIG. 4) (recommendations such as suggesting a replacement, outputting an alert including a recommendation, detecting the location of the mobile terminal, etc.).
