[0002] Various technologies that utilize information related to pressure have been proposed.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-000522 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is room for improvement in the above-mentioned conventional technology. For example, the above-mentioned conventional technology merely notifies the user using information on the sensed pressure, and it is difficult to say that the pressure is effectively utilized.

[0009] Hereinafter, an information processing system and an information processing method according to the present application (hereinafter referred to as "embodiments") will be described in detail with reference to the drawings. Note that the information processing system and the information processing method according to the present application are not limited to these embodiments. Furthermore, the same components in the following embodiments will be denoted by the same reference numerals, and duplicated descriptions will be omitted.

[0010] (Embodiment) [1. Information Processing] [1-1. Overall overview] First, an example of information processing according to the embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of information processing according to the embodiment.

[0011] 1 shows, as an example, an information processing system 1 (see FIG. 2) in which a transmitting device 10 that generates electricity using pressure is placed on a floor F, and a terminal device (user terminal) used by a user U1 is used as a receiving device 20. In FIG. 1, an information processing device 100 that acquires information from the transmitting device 10 (also referred to as a "transmitting device") via the receiving device 20 executes information processing.

[0012] [1-1-1. Information Processing System Configuration] In the following, the configuration of the information processing system 1 will first be described using FIG. 2, and then the processing of FIG. 1 will be described in detail. FIG. 2 is a diagram showing an example of the configuration of the information processing system according to the embodiment. As shown in FIG. 2, the information processing system 1 includes a transmitting device 10, a receiving device 20, a data providing device 50, and an information processing device 100. The transmitting device 10, the receiving device 20, the data providing device 50, and the information processing device 100 are connected to each other via a predetermined network N so as to be able to communicate with each other via wired or wireless communication. Note that the information processing system 1 shown in FIG. 2 may include a plurality of transmitting devices 10, a plurality of receiving devices 20, a plurality of data providing devices 50, and a plurality of information processing devices 100.

[0013] The transmitting device 10 is a device (transmitter) that operates using pressure as a power source and outputs transmitted information. For example, the transmitting device 10 does not have a power supply and outputs transmitted information using power generated by pressure. For example, the transmitting device 10 cannot output transmitted information except when power is generated by pressure, and can output transmitted information only by generating power using pressure. The transmitting device 10 outputs transmitted information via short-range wireless communication. The transmitting device 10 outputs transmitted information using a predetermined communication method such as BLE (Bluetooth Low Energy).

[0014] For example, transmitting device 10 generates electricity from pressure and outputs transmission information at the timing when electricity is generated. Transmitting device 10 does not output transmission information at any time other than the timing when electricity is generated from pressure. Transmitting device 10 generates electricity from stepping pressure, which is the pressure generated when a user (person) steps on it, and outputs transmission information at the timing when electricity is generated. Transmitting device 10 is placed on floor surface F, generates electricity from stepping pressure, and outputs transmission information at the timing when electricity is generated.

[0015] It should be noted that a plurality of transmitting devices 10 may be provided. For example, a plurality of transmitting devices 10 may be arranged side by side along floor surface F, as will be described with reference to FIG. 9. The arrangement of transmitting devices 10 is not limited to the floor surface, and may be any location. Transmitting device 10 may be arranged anywhere as long as it is arranged in a location where pressure can be utilized. For example, transmitting device 10 may be arranged in a shoe worn by a user. In this case, transmitting device 10 is arranged at the bottom of the shoe worn by the user, generates electricity using foot pressure, and outputs transmission information at the timing when power is generated.

[0016] For example, transmitting device 10 varies the intensity at which it outputs the transmitted information depending on the strength of the pressure. Transmitting device 10 may vary the intensity at which it outputs the transmitted information depending on the strength of the stepping pressure, which is the pressure generated when the user steps on the device, as will be described with reference to FIG. 10.

[0017] The receiving device 20 is a device (receiver) that receives the transmission information output (transmitted) by the transmitting device 10. For example, the receiving device 20 receives the transmission information output from the transmitting device 10 via short-range wireless communication. The receiving device 20 receives the transmission information output from the transmitting device 10 using a predetermined communication method such as BLE (Bluetooth Low Energy). The receiving device 20 transmits the transmission information received from the transmitting device 10 to the information processing device 100.

[0018] For example, the receiving device 20 is a terminal device (user terminal) used by the user who generated the pressure. The user terminal is a computer used by the user. The user terminal is realized by, for example, a smartphone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), etc. FIG. 1 shows a case where the user terminal functioning as the receiving device 20 is a smartphone. Note that, hereinafter, the user terminal may be referred to as a user. That is, hereinafter, the user may be read as a user terminal.

[0019] In the following, a user identified by the user ID "U1" may be referred to as "user U1." In this way, in the following, when written as "user U* (* is an arbitrary number)," it indicates that the user is identified by the user ID "U*."

[0020] Note that receiving device 20 is not limited to a user terminal used by a user, and may be any device capable of receiving transmission information output by transmitting device 10. Furthermore, a plurality of receiving devices 20 may be provided. For example, the plurality of receiving devices 20 may be arranged at different distances from transmitting device 10. The plurality of receiving devices 20 may include a receiving device 20 (first receiving device) arranged at a first distance from transmitting device 10, and a receiving device 20 (second receiving device) arranged at a second distance from transmitting device 10 that is longer than the first distance; this point will be described with reference to FIG. 10.

[0021] The data providing device 50 is a server that provides various types of data to the information processing device 100. For example, the data providing device 50 may provide meteorological data such as weather and temperature to the information processing device 100. The data providing device 50 may also provide event information related to the weather in the area where each device is located to the information processing device 100. For example, the data providing device 50 provides open data, which is data that is permitted for wide-open use, to the information processing device 100. For example, the data providing device 50 may be an information processing device that is managed by a local government and provides data held by the local government to an external party. The data providing device 50 may provide various types of data (information) that are permitted for use, including, but not limited to, traffic data such as road information, geospatial information, disaster prevention and mitigation information, procurement information, statistical information, and the like.

[0022] The information processing device 100 is a computer that executes information processing using the transmitted information output by the transmitting device 10. The information processing device 100 is an information processing device that can communicate with various devices via a predetermined network N such as the Internet, and is realized by, for example, a server device or a cloud system. For example, the information processing device 100 is connected to various other devices via the network N so as to be able to communicate with them.

[0023] The information processing device 100 executes information processing using the transmitted information output by the transmitting device 10. The information processing device 100 estimates the user's location based on the transmitted information acquired from the transmitting device 10 that the user stepped on among the multiple transmitting devices 10. The information processing device 100 estimates the location where the user passed by identifying the transmitting device 10 among the multiple transmitting devices 10 that corresponds to the transmitted information. This point will be described with reference to FIG. 9.

[0024] The information processing device 100 executes information processing according to the receiving device 20 that is the sender of the transmitted information among the multiple receiving devices 20. The information processing device 100 estimates the pressing manner of the transmitting device 10 according to the receiving device 20 that is the sender of the transmitted information among the multiple receiving devices 20. The information processing device 100 estimates the state of the user when stepping on the transmitting device 10 according to the receiving device 20 that is the sender of the transmitted information among the multiple receiving devices 20. The information processing device 100 estimates the user's movement manner according to the reception manner from the first receiving device and the second receiving device. When the information processing device 100 receives transmitted information only from the first receiving device, it estimates that the user is walking. When the information processing device 100 receives transmitted information from the second receiving device, it estimates that the user is running. This point will be described with reference to FIG. 10.

[0025] [1-2. Information processing example] First, the flow of information processing by the information processing system 1 (see FIG. 2) will be described using FIG. 1. In FIG. 1, the user U1 before movement and the receiving device 20, which is the user terminal used by the user U1, are shown by dotted lines, and the user U1 and the receiving device 20 after movement are shown by solid lines. FIG. 1 shows, as an example, a case where a transmitting device 10 that generates electricity using pressure is placed on a floor F. For example, in FIG. 1, the transmitting device 10 generates electricity using pressure, and outputs transmission information SD11 at the timing of power generation with a strength that reaches a predetermined short distance (for example, 3 m around), and does not output transmission information SD11 at any other timing than the timing of power generation using pressure.

[0026] A user U1 holding a receiving device 20 moves on a floor surface F (step S11). The user U1 moves on the floor surface F and steps on a transmitting device 10 placed on the floor surface F. As a result, the transmitting device 10 generates power from the pressure (stepping pressure) generated by being stepped on by the user U1 (step S12).

[0027] The transmitting device 10, which generates power using the user U1's pedal pressure, outputs the transmission information at the time of power generation (step S13). In FIG. 1, the transmitting device 10 outputs the transmission information SD11 using the power generated using the user U1's pedal pressure. For example, the transmission information SD11 includes information identifying the transmitting device 10 (device ID) and the date and time when the transmission information SD11 was output. The transmitting device 10 outputs the transmission information SD11 using the power generated using the user U1's pedal pressure with a strength that can reach a predetermined short distance. The transmitting device 10 outputs the transmission information SD11 using the power generated using the user U1's pedal pressure with a strength that can reach the receiving device 20 but cannot reach the information processing device 100, for example. As a result, the receiving device 20 held by the user U1 receives the transmission information SD11 including the information identifying the transmitting device 10 and the date and time when the transmission information SD11 was output. The receiving device 20 receives the transmission information SD11 transmitted by the transmitting device 10.

[0028] The receiving device 20 transmits the transmission information SD11 received from the transmitting device 10 to the information processing device 100 (step S14). The receiving device 20 transmits the transmission information SD11, including information for identifying the transmitting device 10 and the date and time when the transmission information SD11 was output, to the information processing device 100. The receiving device 20 transmits the transmission information SD11 to the information processing device 100, which is located remotely. As a result, the information processing device 100 acquires the transmission information SD11. That is, the information processing device 100 receives the transmission information SD11 transmitted by the transmitting device 10 via the receiving device 20.

[0029] 1, receiving device 20 transmits information identifying user U1 (device ID, user ID, etc.) to information processing device 100 along with transmission information SD11 including information identifying transmitting device 10 and the date and time when transmission information SD11 was output. As a result, information processing device 100 receives transmission information SD11 including information identifying transmitting device 10 and the date and time when transmission information SD11 was output, and information identifying user U1. In other words, information processing device 100 acquires information identifying transmitting device 10 and information identifying user U1.

[0030] The information processing device 100 executes information processing using the acquired transmission information SD11 (step S15). For example, the information processing device 100 estimates a context using the acquired transmission information SD11. The information processing device 100 estimates the context of the user U1 using the acquired transmission information SD11. In FIG. 1, the information processing device 100 estimates the position of the user U1 using information identifying the transmission device 10 and information identifying the user U1, which are included in the transmission information SD11. For example, the information processing device 100 estimates that the user U1 was located at the location of the transmission device 10 indicated by the transmission information SD11 at the date and time the transmission information SD11 was output. Note that the above-described information processing is merely an example, and the information processing device 100 may execute any information processing, which will be described later with reference to FIGS. 9 and 10, etc.

[0031] In this way, in the information processing system 1, the transmitting device 10 generates electricity using pressure and outputs transmission information at the timing of power generation, and the information processing device 100 executes information processing using the transmission information output by the transmitting device 10. In this way, the information processing system 1 transmits transmission information only when power is generated by pressure, thereby suppressing unnecessary transmissions and enabling transmission at the required timing. Therefore, the information processing device 100 can execute information processing appropriately using pressure. As described above, the information processing system 1 can execute information processing appropriately using pressure by using the transmitting device 10 that generates power when pressure is applied and outputs predetermined information via short-range wireless communication when power is generated.

[0032] [1-3. Other processing examples] The above-described process is merely an example, and the information processing device 100 may perform various processes using various information. In this regard, examples are listed below.

[0033] [1-3-1. Example of processing using multiple transmitting devices] Although Fig. 1 has been described as an example in which one transmitting device 10 is installed, multiple transmitting devices 10 may be used. An example of processing using multiple transmitting devices 10 will be described with reference to Fig. 9. Fig. 9 is a diagram showing an example of processing using multiple transmitting devices. Note that explanations of points similar to those in Fig. 1 will be omitted where appropriate.

[0034] 9 shows an example in which a plurality of transmitting devices 10 are placed on floor surface F in FIG. 1. Note that in FIG. 9, receiving device 20 may be a user terminal carried by user U1 as in FIG. 1, or may be receiving device 20 placed in a position where it can receive transmitted information from transmitting device 10.

[0035] In FIG. 9, the transmitting devices 10 are arranged in a plane along the floor surface F. Specifically, in FIG. 9, 35 transmitting devices 10, indicated by 5×7 rectangular areas, are arranged in a plane along the floor surface F. In FIG. 9, M and a two-digit number, such as "M**" (where * is a number), are added to the 5×7 rectangular areas corresponding to each of the 35 transmitting devices 10 to distinguish each transmitting device 10. Specifically, in FIG. 9, M11 to M57 are added to each of the 5×7 rectangular areas to distinguish each of the 35 transmitting devices 10 (hereinafter also referred to as "transmitting devices M11 to M57") arranged in a line on the floor surface F. For example, the 35 transmitting devices 10 may be arranged in any manner as long as they are arranged along the floor surface F, and may be, for example, mats placed on the floor surface F of a store or the like.

[0036] For example, when viewed from above on the floor surface F, the transmitting device M11 is the transmitting device 10 located in the left corner of the 35 transmitting devices 10 arranged on the floor surface F. Furthermore, the transmitting device M21 is the transmitting device 10 arranged above the transmitting device M11 when viewed from above on the floor surface F. Furthermore, the transmitting device M12 is the transmitting device 10 arranged to the right of the transmitting device M11 when viewed from above on the floor surface F.

[0037] For example, the transmitting device M34 is the transmitting device 10 located in the center of the 35 transmitting devices 10 arranged on the floor surface F in a plan view of the floor surface F. Furthermore, the transmitting device M24 is the transmitting device 10 arranged below the transmitting device M34 in a plan view of the floor surface F. Furthermore, the transmitting device M33 is the transmitting device 10 arranged to the left of the transmitting device M34 in a plan view of the floor surface F.

[0038] User U1 moves on floor surface F (step S21). User U1 moves on floor surface F and steps with his / her foot on the area on floor surface F where 35 transmitting devices 10 are arranged. In FIG. 9, user U1 moves on floor surface F and steps with his / her foot on the area on floor surface F where transmitting device M32 is arranged among the 35 transmitting devices 10. As a result, transmitting device M32 generates electricity by the pressure (stepping pressure) generated by being stepped on by user U1.

[0039] The transmitting device M32 generates power using the pedal pressure of the user U1 and outputs transmission information at the timing of power generation. In Fig. 9, the transmitting device M32 outputs the transmission information SD32 using the power generated by the pedal pressure of the user U1. As a result, the receiving device 20 receives the transmission information SD32 including information for identifying the transmitting device M32 and the date and time when the transmission information SD32 was output. The receiving device 20 receives the transmission information SD32 transmitted by the transmitting device M32.

[0040] The receiving device 20 transmits the transmission information SD32 received from the transmitting device M32 to the information processing device 100. The receiving device 20 transmits the transmission information SD32, which includes information for identifying the transmitting device M32 and the date and time when the transmission information SD32 was output, to the information processing device 100. As a result, the information processing device 100 acquires the transmission information SD32. That is, the information processing device 100 receives the transmission information SD32 transmitted by the transmitting device M32 via the receiving device 20.

[0041] The information processing device 100 executes information processing using the acquired transmission information SD32 (step S22). For example, the information processing device 100 estimates a context using the acquired transmission information SD32. The information processing device 100 estimates which location on the floor surface F on which 35 transmitting devices 10 are placed has been passed by a person, using the acquired transmission information SD32. In FIG. 9, the information processing device 100 estimates that the person passed through the location where the transmitting device M32 is placed on the floor surface F on which 35 transmitting devices 10 are placed, based on information identifying the transmitting device M32 included in the transmission information SD32. For example, the information processing device 100 estimates that the person passed through the location where the transmitting device M32 is placed on the floor surface F on which 35 transmitting devices 10 are placed at the date and time when the transmission information SD32 is output.

[0042] [1-3-2. Example of processing using multiple receiving devices] Although Fig. 1 has been described as an example in which one receiving device 20 is installed, a plurality of receiving devices 20 may be used. An example of processing using a plurality of receiving devices 20 will be described with reference to Fig. 10. Fig. 10 is a diagram showing an example of processing using a plurality of receiving devices. Note that explanations of points similar to those in Fig. 1 will be omitted as appropriate.

[0043] 10, the receiving devices 20 are described as receiving devices 20-1 and 20-2 depending on where they are installed. For example, receiving device 20-1 is a receiving device 20 (also referred to as a "first receiving device") that is installed at a first distance from transmitting device 10. For example, receiving device 20-1 is a receiving device 20 (also referred to as a "second receiving device") that is installed at a second distance from transmitting device 10 that is longer than the first distance.

[0044] For example, the first distance is the distance that a signal (transmitted information) output from transmitting device 10 can reach when the pressure on transmitting device 10 is less than a predetermined value and the strength at which transmitting device 10 outputs the transmitted information (also referred to as the "first strength"). For example, the second distance is the distance that a signal (transmitted information) output from transmitting device 10 can reach when the pressure on transmitting device 10 is equal to or greater than a predetermined value and the strength at which transmitting device 10 outputs the transmitted information (also referred to as the "second strength"). Note that receiving devices 20-1, 20-2, etc. will be referred to as receiving device 20 when not being particularly distinguished from one another.

[0045] FIG. 10 illustrates an example in which multiple receiving devices 20 are arranged on a ceiling C. Specifically, in FIG. 10, receiving device 20-1, which is a first receiving device, is arranged on the ceiling C at a first distance FL from transmitting device 10. For example, receiving device 20-1 is arranged in a position where it can receive transmitted information output by transmitting device 10 at a first strength. In other words, receiving device 20-1 is arranged in a position where transmitted information output by transmitting device 10 at a first strength can reach. Note that while FIG. 10 illustrates an example in which the receiving devices 20 are arranged on the ceiling C, the receiving devices 20 may be arranged in any position as long as the distance relationship is satisfied. For example, if the receiving device 20 is arranged indoors, it may be arranged on a floor F or the like. Furthermore, if the receiving device 20 is arranged outdoors, it may be arranged on the ground, such as a road.

[0046] Furthermore, receiving device 20-2, which is a second receiving device, is placed on ceiling C at a second distance SL from transmitting device 10. For example, receiving device 20-2 is placed in a position where it cannot receive transmitted information output by transmitting device 10 at a first strength, but can receive transmitted information output by transmitting device 10 at a second strength. In other words, receiving device 20-2 is placed in a position where transmitted information output by transmitting device 10 at the first strength does not reach it, but transmitted information output by transmitting device 10 at the second strength reaches it.

[0047] In Fig. 10, user U1 moves on floor surface F and steps on transmitting device 10 placed on floor surface F. As a result, transmitting device 10 generates electricity due to the pressure (stepping pressure) generated by being stepped on by user U1. Transmitting device 10 generates electricity due to the stepping pressure of user U1 and outputs transmission information at the timing of power generation.

[0048] First, a case will be described where the pressure (stepping pressure) generated by stepping on by user U1 is less than a predetermined value. When the stepping pressure of user U1 is less than the predetermined value, transmitting device 10 outputs transmission information SD11 at a first strength. That is, when the stepping pressure of user U1 is less than the predetermined value, transmitting device 10 outputs transmission information SD11 at a strength that reaches the first distance but does not reach the second distance. As a result, receiving device 20-1 receives transmission information SD11 transmitted by transmitting device 10. On the other hand, receiving device 20-2 does not receive transmission information SD11 transmitted by transmitting device 10.

[0049] The receiving device 20-1 transmits the transmission information SD11 received from the transmitting device 10 to the information processing device 100. The receiving device 20-1 transmits information identifying the receiving device 20-1 (such as a device ID) together with the transmission information SD11 to the information processing device 100. For example, the information processing device 100 receives information identifying the receiving device 20-1 (also referred to as "first reception information") together with the transmission information SD11.

[0050] The information processing device 100 executes information processing using the acquired outgoing information SD11 and first received information. For example, the information processing device 100 estimates the context of user U1 using the acquired outgoing information SD11 and first received information. In FIG. 10, the information processing device 100 estimates the movement mode of user U1 using the outgoing information SD11 and the first received information. For example, since the information processing device 100 has acquired only the first received information along with the outgoing information SD11, it estimates that user U1 is walking. In other words, the information processing device 100 estimates that user U1 is walking because user U1 is moving with a stepping pressure that reaches only receiving device 20-1 and not receiving device 20-2.

[0051] Next, a case will be described where the pressure (stepping pressure) generated by stepping on by user U1 is equal to or greater than a predetermined value. When the stepping pressure of user U1 is equal to or greater than a predetermined value, transmitting device 10 outputs transmission information SD11 at a second strength. That is, when the stepping pressure of user U1 is equal to or greater than a predetermined value, transmitting device 10 outputs transmission information SD11 at a strength that reaches up to a second distance. As a result, receiving device 20-1 receives transmission information SD11 transmitted by transmitting device 10. Also, receiving device 20-2 receives transmission information SD11 transmitted by transmitting device 10.

[0052] The receiving device 20-2 transmits the transmission information SD11 received from the transmitting device 10 to the information processing device 100. The receiving device 20-2 transmits information identifying the receiving device 20-2 (such as a device ID) together with the transmission information SD11 to the information processing device 100. For example, the information processing device 100 receives information identifying the receiving device 20-2 (also referred to as "second reception information") together with the transmission information SD11.

[0053] The information processing device 100 executes information processing using the acquired outgoing information SD11 and second received information. For example, the information processing device 100 estimates the context of user U1 using the acquired outgoing information SD11 and second received information. In FIG. 10, the information processing device 100 estimates the movement mode of user U1 using the outgoing information SD11 and second received information. For example, since the information processing device 100 has acquired the second received information along with the outgoing information SD11, it estimates that user U1 is running. In other words, the information processing device 100 estimates that user U1 is running because user U1 is moving with a foot pressure that reaches the receiving device 20-2.

[0054] [1-3-3.Applications, etc.] As described above, the information processing system 1 may be applied to any purpose. Examples of this will be described below. Note that the following purposes are merely examples, and the information processing system 1 may be used for various purposes.

[0055] For example, the information processing system 1 may be used for a traffic volume survey, etc. For example, when the information processing system 1 is used for a traffic volume survey, the information processing system 1 can measure the traffic volume by outputting a signal each time the transmitting device 10 is stepped on.

[0056] For example, the information processing system 1 may measure the strength of a person's stepping, the time the person's feet are on the ground, etc., and measure the person's movement state along with their location (whereabouts).The information processing system 1 may also be used to conduct traffic volume surveys for each attribute by acquiring attributes such as the age and gender of the user from the user terminal.

[0057] For example, in the information processing system 1, the resistance value may be designed so that transmitting device 10 operates for only about one second when stepped on once. In this case, more appropriate information processing can be achieved, such as more appropriate estimation of traffic volume, compared to when the charging time is long and a signal is output.

[0058] As described above, in the information processing system 1, the number of receiving devices 20 is determined by the strength of the output (radio waves). The transmitting device 10 changes the distance that can be transmitted depending on the energy of stepping on the power generation unit 12 (pressure element). The transmitting device 10 outputs a signal so that it will reach a longer distance if stepped on harder. Furthermore, in the information processing system 1, by appropriately arranging the receiving devices 20, it is possible to estimate the context of passing objects such as users without installing other sensors.

[0059] For example, in information processing system 1, a response threshold may be set for the pressure sensors of transmitting device 10, and the sensors may be arranged in an array, and the force of the step may be estimated based on whether or not each sensor responds.

[0060] As described above, the transmitting device 10 generates power when pressure is applied. That is, because external pressure is applied to modules such as sensors, the pressure may cause module failure, and because power is not constantly supplied, remote health checks are difficult. Therefore, the information processing system 1 may be used to facilitate maintenance management. For example, the information processing system 1 may install multiple piezoelectric elements and transmission modules in the same location, and determine that there are no failures (healthy) if a majority of the modules are transmitting signals, and determine that maintenance (replacement, etc.) is required if a majority of the modules are not transmitting signals. If the information processing device 100 determines that maintenance (replacement, etc.) is required, it may transmit (notify) information requesting maintenance to an administrator device used by an administrator.

[0061] 2. Configuration of Information Processing Device Next, the configuration of the information processing device 100 according to the embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the configuration of the information processing device 100 according to the embodiment. As shown in Fig. 3, the information processing device 100 has a communication unit 110, a storage unit 120, and a control unit 130. Note that the information processing device 100 may also have an input unit (e.g., a keyboard, a mouse, etc.) that accepts various operations from an administrator of the information processing device 100, and a display unit (e.g., a liquid crystal display, etc.) that displays various information.

Also, in FIG. 4, "context" is illustrated as an abstract symbol such as "CN11," but specific information indicating the user's context is stored. For example, "context" stores information such as "entered building X," "exited building X," "moving on foot," etc.

For example, the "provider" stores information for identifying the receiving device 20 that received the transmitted information from the transmitting device 10 and transmitted it to the information processing device 100. In other words, the "provider" indicates that the information processing device 100 obtained the transmitted information via the receiving device 20 indicated by the provider.

[0081] In the example of FIG. 6, the history information (history information DL11) identified by the history ID "DL11" indicates that it is information corresponding to a transmission (communication) at date and time DA11. The history information DL11 indicates that the transmission information transmitted (communicated) at date and time DA11 is transmission information SD11.
