[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this specification and the drawings, elements similar to those described above with reference to the previous drawings will be designated by the same reference numerals, and detailed descriptions thereof may be omitted as appropriate.

[0014] FIG. 1 is a diagram showing an example of a support system 100. The support system 100 includes a support device 1 and a terminal 2 carried by a user UZ. The support device 1 and terminal 2 are connected to a communication network NT such as the Internet, and are capable of network communication with each other. The support device 1 is a server. The terminal 2 is, for example, a smartphone or a tablet computer.

[0015] The support system 100 is a system that visualizes the amount of carbon dioxide emissions when using a private car and when using public transportation, and encourages user UZ to change their behavior by making user UZ aware that public transportation is an eco-friendly means of transportation.

[0016] Public transportation includes, for example, trains, buses, subways, etc. Private cars are cars other than commercial cars used to transport passengers or cargo for a fee, specifically cars used by users for their own purposes, including leased cars and rental cars.

[0017] When the application program is started, the terminal 2 accumulates the movement history of the terminal 2 in the background and determines the means of transportation.

[0018] In this embodiment, the use of some public transportation facilities is determined based on whether or not a signal transmitted from a transmitter 9 installed in the public transportation facility is received. The transmitter 9 periodically transmits a signal including device-specific ID information and the like via short-range wireless communication such as Bluetooth (registered trademark). Hereinafter, the signal transmitted by the transmitter 9 is also referred to as a "beacon."

[0019] The transmitter 9 may be installed, for example, on a bus BS as shown in FIG. 2, or at a ticket gate GT of a subway SB as shown in FIG.

[0020] In the example of Fig. 2, while user UZ is on bus BS, terminal 2 continues to receive beacons from transmitter 9 installed on bus BS. Based on the beacon reception history, terminal 2 determines that the means of transportation is bus BS.

[0021] In the example of Fig. 3, when user UZ passes through ticket gate GT before and after boarding subway SB, terminal 2 receives a beacon from transmitter 9 installed at ticket gate GT. Based on the reception history of this beacon, terminal 2 determines that the means of transportation is subway SB.

[0022] 4 is a block diagram showing an example of the configuration of the support device 1. The support device 1 is a computer including a processing unit 11, a storage unit 12, and a communication unit 13.

[0023] The processing unit 11 includes a CPU and executes information processing according to a program stored in the storage unit 12. The storage unit 12 includes RAM, ROM, non-volatile memory, etc. The communication unit 13 is an interface that connects the support device 1 to the communication network NT.

[0024] The program may be provided to the support device 1 via a non-transitory storage medium, or may be provided to the support device 1 via a communication line.

[0025] 5 is a block diagram showing an example of the configuration of the terminal 2. Like the assistance device 1, the terminal 2 is also a computer including a processing unit 21, a storage unit 22, and a communication unit 23. The terminal 2 further includes a touch panel 24, a GNSS receiver 25, and an acceleration sensor 26.

[0026] The communication unit 23 includes a communication unit that realizes a communication method of mobile communication or wireless LAN for connecting the terminal 2 to the communication network NT, and further includes a communication unit that realizes short-range wireless communication such as Bluetooth (registered trademark).

[0027] The touch panel 24 integrally includes a display unit and an operation unit. The GNSS receiver 25 detects the position of the terminal 2 based on radio waves received from the GNSS (Global Navigation Satellite System).

[0028] 6 is a block diagram showing an example of the functional configuration of terminal 2. Processing unit 21 of terminal 2 includes a location data acquisition unit 31, a beacon reception unit 32, a movement history determination unit 33, and a history data transmission unit 34. These functional units 31 to 34 are realized by processing unit 21 executing information processing in accordance with a program.

[0029] Furthermore, the processing unit 21 can access a position database 41, a beacon database 42, and a step count database 43. These databases 41 to 43 may be built in the storage unit 22 or may be built in an external storage device.

[0030] The position data acquisition unit 31 acquires the position data of the terminal 2 from the GNSS receiver 25 and registers it in the position database 41. The position database 41 stores the position of the terminal 2 at each time.

[0031] The beacon receiving unit 32 receives beacons transmitted from transmitters 9 installed in public transportation facilities, and registers the time at which the beacons are received in the beacon database 42. The beacon database 42 stores the beacon reception history.

[0032] The step count database 43 stores the step count history of the user UZ based on the vibrations of the terminal 2 detected by the acceleration sensor 26.

[0033] The movement history determination unit 33 calculates the movement history of the terminal 2 based on the position of the terminal 2 at each time stored in the position database 41, and determines the means of transportation used in the calculated movement history of the terminal 2.

[0034] For example, the movement history determination unit 33 calculates the movement speed in the movement history of the terminal 2, and if the movement speed is equal to or less than a threshold and there is a step count history for that period, it determines that the movement history is by walking.Furthermore, if the movement speed is equal to or greater than a threshold and the movement route of the terminal 2 overlaps with a railway line on the map data, the movement history determination unit 33 determines that the movement history is by train.

[0035] Although it is possible to determine travel history using automobiles based on travel speed, it is difficult to determine whether the travel history was a travel history using a private car or a bus. Furthermore, when using the subway, radio waves from GNSS cannot be received, and the location of terminal 2 may not be detected, making it difficult to determine travel history using the subway.

[0036] Therefore, in this embodiment, the movement history determination unit 33 determines the movement history of the terminal 2 as a movement history using public transportation and a movement history using a private vehicle based on the beacon reception history accumulated in the beacon database 42. Specifically, if the movement history determination unit 33 receives a beacon multiple times from one transmitter 9 during the period of the movement history of the terminal 2, or if the movement history determination unit 33 receives beacons from multiple transmitters 9, it determines that the movement history of the terminal 2 is a movement history using public transportation.

[0037] For example, if beacons are repeatedly received from the transmitter 9 during a period of the movement history of the terminal 2, the movement history determination unit 33 determines that the movement history of the terminal 2 is a movement history that uses a bus BS. That is, as shown in Fig. 2, when the user UZ uses the bus BS, the terminal 2 continues to receive beacons from the transmitter 9 installed on the bus BS, so the movement history determination unit 33 determines that the movement history is a movement history that uses a bus BS when the period during which the movement speed is equal to or greater than a threshold matches the period during which beacons were continuously received. On the other hand, if there is no history of receiving a beacon during the period during which the movement speed is equal to or greater than the threshold, the movement history determination unit 33 determines that the movement history is a movement history that uses a private car.

[0038] Furthermore, if the movement history of terminal 2 includes a period in which the location of terminal 2 is unknown during the period from when a beacon is received from one transmitter 9 to when a beacon is received from another transmitter 9, the movement history determination unit 33 determines that the movement history of terminal 2 is a movement history that has used the subway SB. That is, as shown in FIG. 3, when user UZ uses the subway SB, terminal 2 cannot detect the location of terminal 2 during the period from when it receives a beacon at the ticket gate GT before boarding to when it receives a beacon at the ticket gate GT after boarding, and therefore the movement history determination unit 33 determines that the movement history is a movement history that has used the subway SB. Note that an identifier for identifying the station may be included in the beacon, so that even the subway SB line can be identified.

[0039] As described above, by utilizing the reception history of beacons transmitted from transmitters 9 installed in public transportation facilities, it is possible to improve the accuracy of distinguishing between travel history using public transportation facilities and travel history using private cars.

[0040] The history data transmission unit 34 transmits history data including the movement history of the terminal 2 to the support device 1. Each movement history of the terminal 2 included in the history data is accompanied by a determination result of the means of transportation. That is, the history data includes a movement history using public transportation and a movement history using a private car.

[0041] 7 is a block diagram showing an example of the functional configuration of the support device 1. The processing unit 11 of the support device 1 includes a history data acquisition unit 51, a movement history storage unit 52, an emission amount calculation unit 53, and a display data transmission unit 54. These functional units 51 to 54 are realized by the processing unit 11 executing information processing in accordance with a program.

[0042] Furthermore, the processing unit 11 can access a movement history database 61 and a summary database 62. These databases 61 to 62 may be constructed in the storage unit 12 or may be constructed in an external storage device.

[0043] The history data acquisition unit 51 acquires the history data transmitted by the terminal 2. The movement history storage unit 52 registers the acquired history data in the movement history database 61.

[0044] 8, in the movement history database 61, the movement history of the terminal 2 is associated with the discrimination result of the means of transportation. The movement history is represented by a position and a time. Specifically, the movement history database 61 includes fields for "history ID," "position," "time," and "discrimination result."

[0045] "Location" and "Time" represent the change in the location of terminal 2 over time, i.e., the route taken by terminal 2. "Discrimination result" represents the means of transportation, such as walking, bus, subway, or private car. In the travel history using the subway, there are sections where the location is unknown.

[0046] The emission calculation unit 53 calculates the total travel distance and carbon dioxide emissions for each of the travel history using public transportation and the travel history using a private car from the travel history of the terminal 2 accumulated in the travel history database 61 at regular intervals, and compiles the calculation results and registers them in the database 62.

[0047] 9, the summary database 62 includes fields for "period," "distance traveled by private vehicle," "carbon dioxide emissions," "distance traveled by public transportation," "carbon dioxide emissions," and "emissions improvement value." The "period" indicates the target period for which the total travel distance and carbon dioxide emissions are calculated. The target period is, for example, one month.

[0048] "Distance traveled by private car" and "carbon dioxide emissions" represent the total distance traveled by private car and the carbon dioxide emissions. Carbon dioxide emissions for a travel history using a private car are calculated using a conversion rate of 242 g / km, for example.

[0049] "Public transportation distance traveled" and "carbon dioxide emissions" represent the total distance traveled and the carbon dioxide emissions of the travel history using public transportation. The carbon dioxide emissions of travel history using public transportation are calculated using a smaller conversion rate than that for private cars.

[0050] Specifically, the carbon dioxide emissions for travel history using buses are calculated using a conversion rate of, for example, 191 g / km, and the carbon dioxide emissions for travel history using trains or subways are calculated using a conversion rate of, for example, 28 g / km.

[0051] The "emissions improvement value" represents the difference between the total carbon dioxide emissions for a given period and the total carbon dioxide emissions for a given period prior to that period. For example, if the most recent period to be calculated is the "current period" and the period immediately prior to that is the "previous period," the emissions improvement value for the current period is represented by the difference between the total carbon dioxide emissions for the previous period and the total carbon dioxide emissions for the current period.

[0052] The display data transmission unit 54 transmits display data for displaying the calculation results registered in the summary database 62 to the terminal 2. When the terminal 2 receives the display data from the support device 1, it displays the notification screen G based on the display data.

[0053] 10 is a diagram showing an example of a notification screen G displayed on the terminal 2 based on the display data. The notification screen G includes a character string TM indicating the target periods of the previous and current periods.

[0054] In addition, the notification screen G includes a character string CCD representing the total distance traveled in the travel history using a private car in the current period, a character string CCE representing the amount of carbon dioxide emissions, a character string PCD representing the total distance traveled in the travel history using a private car in the previous period, and a character string PCE representing the amount of carbon dioxide emissions.

[0055] In addition, notification screen G includes the character string CPD, which represents the total distance traveled in the travel history using public transportation in the current period, the character string CPE, which represents the amount of carbon dioxide emissions, and the character string PPD, which represents the total distance traveled in the travel history using public transportation in the previous period, and the character string PPE, which represents the amount of carbon dioxide emissions.

[0056] The notification screen G also includes a character string DF that indicates the carbon dioxide emission improvement value from the previous period to the current period.

[0057] The notification screen G also includes a chart CR showing the ratio of travel history using public transportation to travel history using private cars in the current period, and a chart PR showing the ratio of travel history using public transportation to travel history using private cars in the previous period. The ratio may be a ratio of total travel distance or a ratio of carbon dioxide emissions.

[0058] By displaying the above-described notification screen G on terminal 2, the carbon dioxide emissions when using a private car, the carbon dioxide emissions when using public transportation, and the carbon dioxide emission improvement value compared to the comparison period are quantitatively visualized, and user UZ recognizes that public transportation is an eco-friendly means of transportation, which ultimately makes it possible to encourage behavioral changes in user UZ.

[0059] In addition, by awarding decarbonization points to users UZ according to the emission improvement value and making the decarbonization points exchangeable for rewards offered within the community, such as by local governments, it becomes possible to increase the motivation of users UZ to accumulate decarbonization points and further encourage behavioral changes among users UZ.

[0060] 11 is a flow diagram showing an example of the procedure of the support method realized in the support system 100. The processing unit 11 of the support device 1 executes processes S11 to S14 shown in the right half of the figure in accordance with a program. The processing unit 21 of the terminal 2 executes processes S21 to S24 shown in the left half of the figure in accordance with a program.

[0061] First, the terminal 2 calculates the movement history of the terminal 2 based on the position of the terminal 2 at each time stored in the position database 41 (S21, processing as the movement history determination unit 33).

[0062] Next, terminal 2 distinguishes the calculated movement history of terminal 2 into movement history using public transportation and movement history using a private car based on the beacon reception history stored in beacon database 42 (S22, processing as movement history distinguishing unit 33).

[0063] Next, the terminal 2 transmits history data including the movement history of the identified terminal 2 to the support device 1 (S23, processing as the history data transmission unit 34).

[0064] The processes S21 to S23 for calculating and determining the movement history and transmitting the history data may be executed, for example, every time the movement of the terminal 2 is completed, or may be executed at regular intervals such as one day.

[0065] Next, the support device 1 acquires the history data transmitted by the terminal 2 (S11, processing as the history data acquisition unit 51).

[0066] Next, the support device 1 stores the acquired history data in the movement history database 61 (S12, processing as the movement history storage unit 52).

[0067] Next, the support device 1 calculates the carbon dioxide emissions for each of the travel history using public transportation and the travel history using a private car from the travel history of the terminal 2 accumulated in the travel history database 61 (S13, processing as the emission calculation unit 53).

[0068] Next, the support device 1 transmits display data for displaying the calculation result of the carbon dioxide emission amount to the terminal 2 (S14, processing as the display data transmission unit 54).

[0069] The processes S13 to S14 for calculating the carbon dioxide emission amount and transmitting the display data are executed at regular intervals, such as once a week or once a month.

[0070] Next, the terminal 2 displays the calculation result of the carbon dioxide emission amount on the notification screen G (see FIG. 10) based on the display data received from the support device 1 (S24).

[0071] This completes the series of steps in the support method.

[0072] In the above embodiment, the processes S21 and S22 for calculating and determining the movement history are executed on the terminal 2 side, but this is not limited to this. The movement history may be calculated and determined on the support device 1 side by transmitting the position history and beacon reception history of the terminal 2 to the support device 1.

[0073] Furthermore, in the process S13 for calculating the carbon dioxide emission amount, the carbon dioxide emission amount may be calculated by extracting the movement history of the terminal 2 whose starting point or ending point is within a predetermined area from the movement history of the terminal 2 accumulated in the movement history database 61. This makes it possible to target movement histories related to local governments that offer special benefits, for example.

[0074] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made by those skilled in the art.

[0075] Representative embodiments are listed below.

[0076] In a first aspect, the assistance system includes a device carried by a user and a server capable of communicating with the device, the device including an acquisition unit that acquires location data of the device, a receiving unit that receives signals transmitted from transmitters installed in public transportation facilities, and a transmitting unit that transmits history data including a movement history of the device calculated based on the location data to the server, the server including an acquisition unit that acquires the history data transmitted by the device, a calculation unit that calculates carbon dioxide emissions for each of a movement history using public transportation and a movement history using a private car, the calculation being determined based on whether or not the signal was received, and a transmitting unit that transmits display data to the device to display the calculated carbon dioxide emissions. This makes it possible to support behavioral change in users who change their means of transportation from a private car to public transportation.

[0077] As a second aspect, in the first aspect, the terminal may further include a discrimination unit that discriminates the movement history of the terminal into a movement history using the public transportation system and a movement history using the private vehicle, depending on whether or not the signal is received. This makes it possible for the terminal to discriminate between a movement history using the public transportation system and a movement history using the private vehicle.

[0078] As a third aspect, in the second aspect, the determination unit may determine that the movement history of the terminal is a movement history using public transportation when the determination unit receives the signal multiple times from one transmitter or when the determination unit receives the signal from multiple transmitters during a period of the movement history of the terminal. This makes it possible to improve the accuracy of determining movement history using public transportation.

[0079] As a fourth aspect, in the second aspect, the transmitter may be installed on a bus, and the determination unit may determine that the movement history of the terminal is a movement history using a bus when the determination unit repeatedly receives the signal from the transmitter during a period of the movement history of the terminal.

[0080] As a fifth aspect, in the second aspect, the transmitter may be installed at a subway ticket gate, and the determination unit may determine that the movement history of the terminal is a movement history using a subway when the movement history of the terminal includes a period in which the location of the terminal is unknown during a period from when the signal is received from the first transmitter to when the signal is received from the second transmitter. This makes it possible to improve the accuracy of determining movement history using a subway.

[0081] As a sixth aspect, in the first aspect, the display data may include a ratio of the carbon dioxide emissions in the travel history using the public transportation system to the carbon dioxide emissions in the travel history using the private car, thereby making it easier to grasp the ratio of the carbon dioxide emissions.

[0083] As an eighth aspect, in the first aspect, the display data may include a difference between the total amount of carbon dioxide emissions from the travel history using the public transportation system and the travel history using the private car in a predetermined period and the total amount of carbon dioxide emissions from the travel history using the public transportation system and the travel history using the private car in a previous period, thereby making it easier to understand changes in carbon dioxide emissions.

[0084] As a ninth aspect, in the first aspect, the calculation unit may extract, from the movement history of the terminal, movement history whose start point or end point is included in a predetermined area, and calculate the carbon dioxide emission amount. This makes it possible to calculate the carbon dioxide emission amount for movement history related to the predetermined area.

[0085] In a tenth aspect, the support method acquires location data of a device carried by a user, receives a signal transmitted from a transmitter installed in public transportation, classifies a movement history of the device calculated based on the location data into a movement history using public transportation and a movement history using a private car depending on whether the signal was received, calculates carbon dioxide emissions for the movement history using public transportation and the movement history using the private car, and displays the calculated carbon dioxide emissions on the device. This makes it possible to support a behavioral change in a user who changes their means of transportation from a private car to public transportation.

[0086] In an eleventh aspect, the assistance device includes an acquisition unit that acquires history data including travel history using public transportation and travel history using a private car transmitted from a terminal carried by a user, a calculation unit that calculates carbon dioxide emissions for each of the travel history using public transportation and the travel history using the private car, and a transmission unit that transmits display data to the terminal to display the calculated carbon dioxide emissions. This makes it possible to support behavioral change in a user who changes their means of transportation from a private car to public transportation.

[0087] In a twelfth aspect, the program causes a computer to acquire history data transmitted from a user's terminal, the history data including travel history using public transportation and travel history using a private car, calculate the amount of carbon dioxide emissions for each of the travel history using public transportation and the travel history using a private car, and transmit display data for displaying the calculated carbon dioxide emissions to the terminal. This makes it possible to support behavioral change in users who switch from a private car to public transportation.

[0088] In a thirteenth aspect, the program causes a computer of a terminal carried by a user to acquire location data of the terminal, receive signals transmitted from transmitters installed in public transportation facilities, and distinguish a movement history of the terminal calculated based on the location data into a movement history using public transportation facilities and a movement history using a private car depending on whether the signal was received. This makes it possible for the terminal to distinguish between a movement history using public transportation facilities and a movement history using a private car. [Explanation of symbols]
