Description

[Technical field]

[0001] The present invention relates to a lifestyle information estimation device and a lifestyle information estimation system that estimate lifestyle information of a predetermined area. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there are services that provide demographic information created using the mechanisms of mobile phone networks (see, for example, Non-Patent Document 1).

[0003] 24 to 26 are diagrams showing an overview of a service that provides such demographic information.

[0004] 24 to 26, "Mobile Spatial Statistics (registered trademark)" provided by NTT DoCoMo, Inc. is described as an example.

[0005] Such "Mobile Spatial Statistics (registered trademark)" is explained in, for example, Non-Patent Document 2.

[0006] "Mobile Spatial Statistics (registered trademark)" is demographic information created using the mechanisms of mobile phone networks. This spatial statistics is demographic information that shows only the number of people in a group, and so has the characteristic that it cannot identify individual mobile phone or smartphone users. In this respect, it differs from the treatment of so-called "personal information," and it is possible to provide third parties with demographic information for a certain area at a certain time without obtaining the consent of the person to whom the information belongs.

[0007] Here, this spatial statistics makes it possible to grasp the population distribution for every hour of Japan, 24 hours a day, 365 days a year. Moreover, this spatial statistics makes it possible to grasp the population structure by gender, age group, and residential area, making it possible to conduct analyses tailored to the purpose. Since the service started in October 2013, it has been widely used by the Japan Tourism Agency, local governments, private companies, etc.

[0008] More specifically, mobile phone networks periodically track the mobile phones located in each base station area so that users can make calls and send emails anytime, anywhere. Using this system, the number of mobile phones can be tallied and the population can be estimated by taking into account the penetration rate of mobile phone carriers. This is Mobile Spatial Statistics (registered trademark).

[0009] Demonstration experiments were carried out in the public sector, such as urban development and disaster prevention planning, and it was confirmed that this spatial statistics could be widely used in society. As mentioned above, the service was launched in October 2013 so that it can be used not only in the public sector but also in academic and industrial fields.

[0010] This spatial statistics makes it possible to analyze data by gender, age group, and residential area (domestic residents), and by country and region (foreign visitors to Japan), and by time period according to purpose.

[0011] As shown in Figure 24(a), the statistical target area is the nationwide DoCoMo service area, and the population distribution throughout the country can be grasped every hour. Therefore, the population distribution can be grasped every hour, 24 hours a day, 365 days a year.

[0012] As shown in Figure 24(b), this demographics makes it possible to grasp the population structure by gender and age group, covering the age range of 15 to 79 years old.

[0013] Furthermore, as shown in Figure 25, this spatial statistics makes it possible to grasp the population by residential area in a specific time period (every hour) in a specific area, which, as mentioned above, makes it possible to grasp the population distribution by residential area based on registered mobile phone information.

[0014] Furthermore, assuming that spatial statistical information is available, technology has been proposed for understanding and predicting "people flow" using demographic information as input data (see, for example, non-patent document 3).

[0015] According to Non-Patent Document 3, "demographic data" can be classified into "trajectory data" and "aggregated data." "Trajectory data" is data related to moving objects such as people, and is often acquired by portable terminals such as smartphones and car navigation systems.

[0016] On the other hand, "aggregated data" is data associated with a location, and is collected by traffic volume sensors installed on roads, wireless base stations, and so on. Because data is acquired by equipment installed in specific locations, once the equipment is installed, data can be collected fairly comprehensively. In addition, because the data is not tied to individual subjects, there are fewer privacy concerns, and it is highly likely that data measured once can be used for a variety of purposes. On the other hand, because information across locations cannot generally be obtained, there are limitations to its use when understanding the flow of people in a city.

[0017] Demographic information is a type of aggregate data that records the population by location and time in a city. Most demographic information records population information by area and time. When targeting information over a wide area, mobile phone information is often used in consideration of comprehensiveness. The number of terminals in each area is counted based on terminal connection information at mobile phone base stations and information such as CDR (Call Data Record), and the actual population is estimated while taking into account the utilization rate by attribute, and this is used as demographic information.

[0018] The "spatial statistics" described in the above-mentioned Non-Patent Documents 1 and 2 correspond to "demographic information" in this sense.

[0019] FIG. 26 is a diagram showing a data aggregation procedure in "Mobile Spatial Statistics (registered trademark)" disclosed in Non-Patent Document 2.

[0020] Referring to FIG. 26, in this "spatial statistics", the following processing is carried out to ensure safety by eliminating information that can identify individuals.

[0021] As mentioned above, in order to strictly protect customer privacy, this spatial statistic is demographic information that represents only the number of people in a group, and therefore cannot identify individual users.

[0022] The spatial statistics are created through the following steps: i) De-identification: The process of removing identifying information, such as name, telephone number, date of birth, etc. from operational data. ii) Aggregation processing: Processing to derive statistical "group-related information" by making statistical inferences from de-identified information. iii) Confidentiality processing: Processing to prevent figures from small population areas from being included in the tabulation results

[0023] In addition, Non-Patent Document 3 discloses a technology for performing people flow analysis in order to more effectively utilize demographic information, in which input is demographic information corresponding to multiple time periods, and based on that, it executes a task of outputting the amount of movement between cells between times.

[0024] On the other hand, when using two-dimensional information, there is a technology for a system that distributes demographic data of large meshes to small meshes based on estimated information of building area (see, for example, Patent Document 1).

[0025] FIG. 27 shows an overview of the "Basic Survey on Social Life" (Non-Patent Document 4) issued by the Statistics Bureau of the Ministry of Internal Affairs and Communications.

[0026] As shown in Figure 27, the Basic Survey on Social Life surveys collects lifestyle information (behavioral classification) in 15-minute increments by region, age, and sex. [Prior art documents] [Patent documents]

[0056] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0057] In the following, a description will be given of an information processing system for estimating lifestyle information (hereinafter, referred to as a "lifestyle information estimation system") and the configuration of a lifestyle information estimation device for estimating lifestyle information in the lifestyle information estimation system.

[0058] As described below, the lifestyle information estimation device in each of the following embodiments is a device that estimates lifestyle information for a predetermined time period in a predetermined area based on demographic information of the area.

[0059] In addition, the lifestyle information estimation device in each of the following embodiments is a device that estimates and analyzes people flow information, for example, information on people distribution, during a specified time period related to an analysis target area specified by a user, based on demographic information of the specified area.

[0060] FIG. 1 is a diagram showing an overview of a lifestyle information estimating system according to a first embodiment of the present invention.

[0061] Referring to FIG. 1, a life information estimation system 1000 according to a first embodiment of the present invention includes a life information service providing server 2000 that operates as a life information estimation device, a life information user terminal 3000 of a user who receives services from the life information service providing server 2000, data providing servers 5000.1 to 5000.M (M: a natural number) that provide the life information service providing server 2000 with data necessary for estimating life information as described below, a building information registration terminal 4000 that registers building information as described below, and a mobile phone or smartphone 200 that is used by a user 100 to receive services as described below.

[0062] Here, the building information registration terminal 4000 is a terminal for a building owner or manager to register building information (floor plan, 2D or 3D polygon data, etc.). In addition, visitors to the building may register information such as photos of the interior of the building. In this case, the building information registration terminal 4000 may be, for example, a mobile terminal such as a smartphone having a photo-taking function. For example, in the case of a smartphone, the life information service providing server 2000 may be configured to receive notifications from users who use terminals that have installed application software having an input format that notifies the user of the building name, number of floors, and area information (for example, store name and type of store) along with the captured photo.

[0063] FIG. 2 is a functional block diagram showing an outline of the system of the life information service providing server 2000. As shown in FIG.

[0064] 4 is a diagram for explaining the contents of data provided from the data providing servers 5000.1 to 5000.M. Note that hereinafter, when the data providing servers 5000.1 to 5000.M are collectively referred to, they will simply be referred to as "data providing server 5000."

[0065] With reference to FIG. 2, the life information service providing server 2000 includes a computing device 2100 and a storage device 2300 .

[0066] The storage device 2300 first stores predetermined "demographic information 2302." Here, the "demographic information 2302" includes at least information on the number of people present in a predetermined area at a predetermined time.

[0067] Here, the "predetermined time" refers to, for example, a first predetermined time interval, for example, every hour, and the "predetermined area" refers to, for example, an area in a specific region, for example, a first area mesh unit, for example, a 500m mesh (a square of 500m on each side). The "predetermined demographic information" is "demographic data" and means "aggregated data", and corresponds to, for example, the above-mentioned "Mobile Spatial Statistics Information (registered trademark)" as shown in FIG. 4.

[0068] Furthermore, the storage device 2300 stores a predetermined "lifestyle information 2306". The "lifestyle information 2306" includes at least information related to a person's life. Here, the predetermined "lifestyle information 2306" is, more specifically, information on a classification of a predetermined behavior by region, age, and sex, in a second time interval that is shorter than a first predetermined time interval and is preferably a divisor of the first time interval. Here, the "lifestyle information" corresponds to information in a database based on the "Basic Survey on Social Life" by the Ministry of Internal Affairs and Communications, which classifies behaviors into 20 predetermined types by region, age, and sex, and in 15-minute increments, as shown in FIG. 4. Here, the "classification of behavior" corresponds to classifications such as "sleep", "commuting", "school", "work", and "academic work".

[0069] The storage device 2300 also stores "occupation-specific employment information 2308." Here, the "occupation-specific employment information 2308" is data showing the employment ratio of each occupation by age and sex, and corresponds to information in the Ministry of Internal Affairs and Communications' Labor Force Survey database, for example, as shown in FIG.

[0070] In addition, the "predetermined living information" may include such "occupation-specific employment information."

[0071] Therefore, the life information estimation unit 2110 can estimate the number of people by behavior (hereinafter, referred to as "number of people by behavior") who are present in the "predetermined area" set by the area setting unit 2106 in response to an instruction from a user, during the "second time interval", based on the "demographic information 2302" and the "predetermined life information 2306". Furthermore, by applying the "employment information by occupation" to the "number of people by behavior" estimated in this way for people with the behavior classification of working or studying, the life information estimation unit 2110 can calculate the classification data of the "occupation" of people who are present in the "predetermined area" during the "second time interval". Note that the "occupation" may not only be the so-called "type of occupation", but may also be any "task" such as "study" that is not a business, but in which a person is obviously engaged in the same behavior for a certain period of time or more in that place (facility / building).

[0072] Although the life information 2306 is described as a "classification of a predetermined behavior" at a second time interval that is shorter than the first time interval and is preferably a divisor of the first time interval, the second time interval may be, for example, the same as the first time interval. For example, after a "classification of a predetermined behavior" is roughly estimated at the first time interval and life information, people flow, and people distribution are presented to the user, a "classification of a predetermined behavior" at a finer "second time interval" may be estimated in response to an instruction from the user, and life information, people flow, and people distribution may be presented to the user.

[0073] The storage device 2300 further stores a predetermined "area location information 2310". Here, the "predetermined area location information" refers to "information on a predetermined place existing in the above-mentioned predetermined area (including information on the type of job at that place)". For example, the "area location information" preferably includes information on buildings and facilities in the area of ​​the second area mesh unit, which is smaller than the above-mentioned first area mesh unit and preferably has a divisor of each side when the first area mesh unit is a rectangle, and information on the types of jobs performed in the buildings and facilities. For example, as shown in FIG. 4, the "area location information 2310" corresponds to map data including information on buildings and facilities in a town, information on the types of jobs performed in the buildings and facilities, and information on roads and water areas in 62.5m mesh units. Some of this "map data" is provided by private companies.

[0074] Based on such area location information 2310, the area information estimation unit 2108 estimates the area corresponding to each job type in the total floor area of ​​facilities and buildings existing in the "predetermined place" of the "predetermined area" set by the area setting unit 2106. Note that such estimation is preferably performed in areas in units of second area meshes. However, depending on the user's settings, such estimation can also be performed in units of first area meshes, each side of which is a multiple of the second area mesh.

[0075] Therefore, the lifestyle information estimation unit 2110 of the calculation device 2100 of the lifestyle information service providing server 2000 calculates and outputs information on the work of people located at a specified location in a specified area at the second time interval (hereinafter referred to as "people's area lifestyle information") by expanding (for example, proportionally allocating) the "number of people per occupation" into the "area corresponding to each occupation" of the "specified location."

[0076] For example, when calculating such "human area life information," the classification of "tasks" that people are engaged in at a certain location (facility / building) within the target area is calculated according to the method described above.

[0077] As the relationship between the predetermined life information and the predetermined area location information, for example, it is possible to assume that during a certain time period, doctors and nurses work at hospital facilities, farmers work on farmland, fishermen work at fishing grounds, housewives raise children, pensioners live in houses, etc. The specific processing will be described later.

[0078] Furthermore, the map output unit 2104 generates and outputs a screen that displays the thus estimated "personal area life information" in association with each "predetermined place" in the "predetermined area" (for example, superimposed on the map information). By generating such an output, the user can visually grasp the life information of people in the "predetermined area" that he or she has specified.

[0079] As described above, since the "number of people by behavior" or the "number of people corresponding to people's area life information" is calculated for each area in the second area mesh unit and at the second time interval, the people flow path information estimation unit 2102 can be configured to estimate and output people flow path information (the route along which people moved) by tracking changes in the number of people distribution for the area in the second area mesh unit and its surrounding areas along the time axis and integrating this with "information on routes along which people can move" (for example, roads, railways, etc.) on the map data. The output result of the people flow path information output unit 2102 is stored in the people flow path information 2312 of the storage device 2300.

[0080] In addition, by associating pedestrian flow information with traffic route information, the pedestrian flow path information estimation unit 2102 can also estimate information on the amount of people moving along each traffic route, and store the estimation results in the storage device 2300 as traffic route information 2304.

[0081] FIG. 3 is a diagram for explaining the hardware configuration of the life information service providing server 2000. As shown in FIG.

[0082] 3, the life information service providing server 2000 may be configured such that a calculation device (CPU: Central Processing Unit) in its own housing executes calculation processing, or a part of the program processing may be further executed on another server. In the following, the description will be given assuming that the calculation device in its own housing executes the calculation processing.

[0083] Referring to FIG. 3, server 2000 includes a computer device 2010, a network communication unit 2012 for communicating with a network, a recording medium (e.g., a memory card) 2210 for recording data from the outside and providing the data to computer device 2010, a keyboard 2400 as an input device, and a display 2420 as a display device.

[0084] For example, a USB memory, a memory card, or an external storage device can be used as the recording medium 2210. Also, for example, a communication function of a wired LAN or a wireless LAN can be used as the network communication unit 2012. The network communication unit 2012 and the input / output interface 2090 configure a communication interface.

[0085] As shown in FIG. 3, the computer main body constituting the computer device 2010 includes, in addition to the disk drive 2030 and the memory drive 2020, a CPU (Central Processing Unit) 2100 connected to a bus 2050, a memory 2200 including a ROM (Read Only Memory) 2200.1 and a RAM (Random Access Memory) 2200.2, a non-volatile rewritable non-volatile storage device 2300, and an input / output interface 2090 for communicating via a network and sending and receiving data with the outside. For example, a HDD (Hard Disc Drive) or an SSD (Solid State Drive) is used as the non-volatile storage device 2300. In the following description, it is assumed to be an SSD. An optical disk can be attached to the disk drive 2030. A memory card 2210 can be attached to the memory drive 2020.

[0086] When the programs of the computer device 2010 operate, the data and programs that store the information that is the basis for the operation of the computer are stored in the SSD 2300.

[0087] 3, the medium capable of recording information such as a program to be installed in the computer main body may be, for example, a DVD-ROM (Digital Versatile Disc), a memory card, a USB memory, etc. In order to accommodate such cases, the computer main body is provided with a drive device (memory drive 2020, disk drive 2030) capable of reading such media.

[0088] The main components of the computer device 2010 are computer hardware and software executed by the CPU 2100. Generally, such software is stored in a storage medium and distributed or distributed via a network, and is acquired via the disk drive 2030 or the network communication unit 2012 and temporarily stored in the SSD 2300. The software is then read from the SSD 2300 to the RAM 2200.2 in the memory and executed by the CPU 2100. Note that, when connected to a network, the software may be directly loaded into the RAM and executed without being stored in the SSD 2300.

[0089] When a program for functioning as computer device 2010 is distributed, the program does not necessarily need to include an operating system (OS) that causes computer main body 2010 to execute functions of an information processing device, etc. The program only needs to include an instruction portion that calls appropriate functions (modules) in a controlled manner and produces desired results. How computer system 2010 operates is well known, and a detailed description will be omitted.

[0090] Furthermore, the CPU 2100 may be a one-core processor or a multiple-core processor, i.e., a single-core processor or a multi-core processor. The server 2000 may also be configured with multiple servers to execute distributed processing.

[0091] The hardware configurations of the lifestyle information user terminal 3000 and the data providing servers 5000.i (1≦i≦M) are basically the same, and therefore the description thereof will not be repeated.

[0092] Fig. 5 is a first diagram illustrating the processing flow of the life information service providing server 2000. Fig. 6 is a second diagram illustrating the processing flow of the life information service providing server 2000.

[0093] FIG. 7 is a diagram showing an outline of data output from the arithmetic device 2100. As shown in FIG.

[0094] FIG. 8 is a conceptual diagram showing data generated when facility population estimation is performed from behavior-specific population estimation at a first time point.

[0095] FIG. 9 is a conceptual diagram showing data generated when facility population estimation is performed from behavior-specific number of people estimation at a second time point.

[0096] 5 and 6, when the process starts, the calculation device 2100 acquires spatial statistical data via the network (S110, S200).

[0097] As mentioned above, to obtain spatial statistical data, it is possible to use "Mobile Spatial Statistics (registered trademark)" provided by NTT DoCoMo. Spatial statistical data is, for example, data on the number of people by age and sex in a given time unit (for example, 1 hour) within a mesh of a given width (for example, 500m square).

[0098] Next, for a "predetermined area" specified by the area setting unit 2106 based on the user's designation, the lifestyle information estimation unit 2110 classifies people (whose age and gender are obtained from the spatial statistical data) who are staying in a specific area (for example, the Umeda area of ​​Osaka) during a specific time period (for example, a certain hour) into states (behavior classification information) such as work and movement (for example, commuting) in more detailed time units (for example, 15 minutes) within this specific time period, referring to the Basic Survey of Social Life database, and estimates the number of people in each category (attributes of age and gender) (S120, S210).

[0099] The lower part of Figure 7(a) shows an overview of such estimation of the number of people by behavior.

[0100] The lower diagram in Figure 8 shows the estimated number of people by activity in a specific area at 2 a.m. Given the time of day, most people's activities are classified as "sleeping."

[0101] The lower graph in Figure 9 shows the estimated number of people by activity in a specific area at 3:00 p.m. (15:00). Judging from the time of day, most people are classified as "working" or "studying."

[0102] Returning to FIG. 5 and FIG. 6 , further, the lifestyle information estimation unit 2110 estimates the number of employees (age and gender attributes) by occupation type for every 15 minutes for the above-mentioned specific area based on the estimated number of people (age and gender attributes) for each behavior category, for example, based on the Ministry of Internal Affairs and Communications Labor Force Survey database (S130, S220).

[0103] Next, the area location information estimation unit 2108 expands (for example, proportionally apportions) the estimated number of employees (attributes of age and sex) by occupation type for every 15 minutes to each building (facility) on the map based on the total floor area of ​​the facility / building and the area allocated to the occupation type of each facility / building, and estimates aggregated data of the number of people in a mesh (for example, a 62.5 m mesh) that is smaller than the unit mesh of the spatial statistical data (S140, S230).

[0104] In the following, when the estimation processing functions of the "area place information estimation unit 2108" and the "lifestyle information estimation unit 2110" are collectively referred to as an "area lifestyle information output unit."

[0105] The upper part of Fig. 7(a) shows an overview of such facility occupancy estimation.

[0106] The upper diagram in Figure 8 shows the results of estimating the number of people in facilities in a specific area at 2 a.m. Judging from the time of day, most people are located in "residences" or "hotels and inns."

[0107] The upper diagram in Figure 9 shows the results of facility population estimation in a specific area at 3:00 p.m. (15:00). Based on the time of day, it can be seen that most people are assigned to the "occupation" or "task" corresponding to the facility or building in each facility.

[0108] 5 and 6, the map output unit 2104 further superimposes the number of people deployed for each facility / building on the map and outputs it by color-coding, for example, using a heat map method. Here, when displaying the heat map, a method of displaying a chart showing the ratio of the number of people doing the work at that location by color coding may be used.

[0109] FIG. 7(b) is a diagram showing an example of an output that visualizes such a distribution of the number of people.

[0110] FIG. 10 is a diagram showing the concept of the process of improving the accuracy of spatial resolution in the behavior-specific number of people estimation process (S120, S210).

[0111] As shown in Figure 10, when conducting analysis using various information such as spatial statistical data (or people flow data) and map information, some data may have a spatial resolution of 500m, other data may have a spatial resolution of 100m, and still other data may have a spatial resolution of land lot number (address unit).

[0112] Because the units of the data do not match, analysis usually ends up being performed based on data with larger units.

[0113] However, as described above, in the life information service providing server 2000, people flow data (including number distribution data at a specific point in time), building data, facility data, land data (including information on roads, railways, roads and water bodies), etc. are all decomposed and converted into the same unit (area mesh) and stored.

[0114] Hereafter, such a database stored in the same unit will be referred to as a "data lake." Therefore, for example, it is possible to perform real-time analysis in the same unit (area mesh) at any point in Japan.

[0115] As described above, the same area mesh has a side length of 62.5 m, as shown in FIG.

[0116] If the resolution is 62.5 m, since Mobile Spatial Statistics (registered trademark) is a mesh with sides of 500 m, it is possible to create an area mesh with sides of 1 / 8 (1 / 8) of this 500 m, which is approximately the distance a person walks in one minute. When using other spatial statistics, it is possible to unify the area mesh with sides equivalent to the distance a person walks in one minute in the same way. By using the distance a person walks in one minute, it can be said that the resolution is suitable for analyzing people flow, including people who are moving by foot, for example.

[0117] However, it is possible to divide it into units smaller than 62.5 m (for example, the smallest unit of 1 m). However, this would increase the amount of data to be analyzed and the amount of calculation, so from the viewpoint of cost-effectiveness, it is preferable to use, for example, 62.5 m.

[0118] FIG. 11 is a diagram showing another example of the map image and the superimposed image of the number of people distribution output by the map output unit 2104. In FIG.

[0119] As shown in FIG. 11, it is also possible to designate an area of ​​a certain size as the specified region, and furthermore, to allow the user to specify a portion of that area as the "specified region" in which the estimation process will be performed. [Embodiment 2]

[0120] FIG. 12 is a functional block diagram for explaining the configuration of a people flow information service providing server 2000' according to the second embodiment.

[0121] The hardware configuration of the people flow information service providing server 2000′ is similar to that described in FIG. 3, and therefore description will not be repeated. In this specification, the “lifestyle information service providing server 2000” and the “people flow information service providing server 2000′” are collectively referred to as the “lifestyle information estimation device.”

[0122] In this specification, "people flow information" refers to information expressing "people movement patterns" during a specified period of time, and includes, for example, information on people distribution estimated regarding the number of people staying in a user-specified area (hereinafter, "specific area") at a specific time or time period for set human attributes. By tracking changes in such people distribution information over time, it is possible to estimate information expressing people flow. Note that "people attributes" here include, for example, age, generation, gender, occupation classification, etc., but are not limited to these.

[0123] The same components as those of the life information service providing server 2000 in the first embodiment are given the same reference numerals, and in principle, description thereof will not be repeated.

[0124] Referring to FIG. 12, the arithmetic device 2100 of the people flow information service providing server 2000′ of embodiment 2 includes, as functions executed according to a program, a people flow information estimation unit 2103 instead of the people flow path information estimation unit 2102, and an area setting unit 2107 instead of the area setting unit 2106.

[0125] The people flow information estimation unit 2103 will be described later.

[0126] The area setting unit 2106 has a function of specifying a "predetermined area (a "specific area" specified by the user as an analysis target)" by specifying, for example, a building, an administrative district, etc., according to instructions from the user. In contrast, the area setting unit 2107 has a function of specifying a "specific area" as an area to be analyzed by the user specifying a building, an administrative district, etc. on the displayed map, as well as specifying the boundary of the area by operating a mouse, a touch panel, etc.

[0127] Furthermore, the storage device 2300 of the people flow information service providing server 2000' stores map information 2314 in the form of a digital map, as will be described later.

[0128] Therefore, the storage device 2300 of the people flow information service providing server 2000' stores demographic information (e.g., "Mobile Spatial Information (registered trademark)") equivalent to demographic information, life information, and area location information as data acquired from an external server via the network. The demographic information is aggregated data of demographic data for each first time interval (e.g., 1 hour), and is information on the age, sex, and number of people by place of residence of people located for each area mesh (e.g., 500 m square) in a predetermined area at the first time interval. On the other hand, the predetermined time unit of the life information is a second time interval (e.g., 15 minutes) shorter than the first time interval, and the life information is information that can associate a person's age, sex, and a predetermined classification of the person's life and behavior with a person's occupation. The location information for each predetermined section of the area location information includes information on the total floor area of ​​facilities in the predetermined area and the occupations in the facilities. The computing device 2100 of the people flow information service providing server 2000' executes a function as an area life information output unit that estimates and outputs area life information of people located in a specified area at least at a specified time based on the relationship between the specified life information and the specified area location information based on the demographic information, life information, and area location information based on the program. More specifically, the life information estimation unit 2110 i) estimates the number of employed people by occupation type located in the specified area for each second time interval based on the demographic information and the life information, and ii) allocates the number of employed people by occupation type to each facility based on the total floor area and the area allocated to the occupation type of each facility, and estimates aggregate data of the number of people in a mesh smaller than the area mesh of the demographic information.

[0129] Furthermore, the storage device 2300 stores stay type information in association with the demographic data. As described above, the demographic information is aggregated data of the demographic data for each first time interval, and is information on the number of people for each attribute (e.g., age and sex) of people present in each area mesh in a given area during the first time interval. Here, the attribute of people includes stay type information of people staying in the given area.

[0130] As will be described later, the "stay type information" includes attributes of residents in a given area, attributes of workers in a given area, and attributes of persons other than residents and workers.

[0131] The arithmetic device 2100 further executes the function of the people flow information estimation unit 2103 that analyzes people flow information within the analysis target area. The life information estimation unit 2110 of the arithmetic device 2100 estimates the number of people for each classification of human behavior located in the area mesh included in the analysis target area for each first time interval based on demographic information and predetermined life information (behavior information and occupation type information), and performs human behavior information estimation. The area place information estimation unit 2108 estimates aggregate data for each estimated area mesh in the analysis target area by distributing the number of people estimated by the life information estimation unit 2110 to the estimated area mesh based on the estimation result of the life information estimation unit 2110 and the type and size of the place (building, facility, road, transportation, etc.) corresponding to the classification of human behavior for each "estimated area mesh (for example, 62.5 m square)". The people flow information estimation unit 2103 estimates the distribution of human attributes (including gender, age or generation, occupation, type of stay, etc.) specified by the user within the analysis area based on the classification and aggregated data of human behavior estimated in the estimated area mesh existing within the analysis area.

[0132] Furthermore, although not limited thereto, similarly to the first embodiment, it is desirable that the lifestyle information estimation unit 2110 not only performs estimation for a first time unit based on demographic information and predetermined lifestyle information, but also estimates the number of people for each category of human behavior present in an area mesh included in the analysis target area for each second time unit shorter than the first time unit.

[0133] FIG. 13 is a conceptual diagram showing an aspect in which a predetermined area RM is designated on a digital map.

[0134] A predetermined area RM is displayed as a digital map as shown in Fig. 13. At this time, a road Rd and a river RV are displayed on the digital map.

[0135] FIG. 14 is a conceptual diagram for explaining the data structure of a digital map.

[0136] As shown in FIG. 14, the digital map data consists of multiple layers.

[0137] For example, the map information stored as "management data" (not shown) includes the secondary mesh code, base map used, geomagnetic declination, actual distance of the corner sides, update date of each data, number of records for each data, number of items for each data, etc.

[0138] For example, layer 1 is road information, and is stored in the map information 2314 as a road information DB.

[0139] Also, for example, the road information may be divided into "basic road data" and "minor road data."

[0140] Here, the "basic road data" is not particularly limited, but includes, for example, "basic road node data," "basic road link data," "basic road link attribute data," etc. Also, the "narrow road data" is not particularly limited, but includes, for example, "narrow road node data," "narrow road link data," "narrow road link attribute data," etc.

[0141] Here, "node data" (a collective term for "basic road node data" and "minor road node data") includes node numbers, position coordinates, altitude, node type, number of connecting links, connecting node numbers, etc. In addition, "basic road node data" also includes intersection names.

[0142] "Link data" (a collective term for "basic road link data" and "minor road link data") includes the link number (start and end node number), road administrator, road type, administrative district code, link length, width classification, number of lanes, and position coordinates and elevation of interpolation points. "Basic road link data" further includes route number, roadway width, road census data (median lane width, 12-hour traffic volume, travel speed (peak time), speed limit and other traffic regulations), position coordinates and elevation of interpolation points, emergency transportation road classification, expressway numbering, etc. "Narrow road link data" further includes the corresponding basic road link number.

[0143] "Link attribute data" (a collective term for "basic road link attribute data" and "minor road link attribute data") includes the location and name of link attributes (bridges, overpasses, tunnels, caverns, railroad crossings, pedestrian bridges, toll booths, underpasses, areas expected to be flooded, etc.).

[0144] Therefore, road information generally consists of node data for identifying the positions of road intersections, link data indicating the types of roads connecting the nodes, and link attribute data indicating the types of links.

[0145] Furthermore, layer 2 may be, for example, building information as described below, layer 3 may be, for example, contour lines, layer 4 may indicate, for example, water bodies (rivers, lakes, ponds, etc.), and layer 5 may indicate, for example, administrative divisions (prefectural borders, city / town / village boundaries, block boundaries, etc.).

[0146] A digital map may also have other layers that contain information on the map.

[0147] The road information may conform to the contents of the following databases. https: / / www.drm.jp / database /

[0148] Furthermore, the information on administrative boundaries may be structured in accordance with the Geospatial Information Authority of Japan database.

[0149] FIG. 15 is a conceptual diagram showing an example of building information.

[0150] The building information is a collection of information on each building or facility having the following configuration, for example.

[0151] Information on individual buildings consists of information such as building ID, building name, latitude and longitude of the building's representative point, building use, building height (height from the reference point), number of floors (underground, above ground), total floor area, and floor plan information for each floor.

[0152] The "representative point of a building" is, for example, the position of the entrance to the building.

[0153] The "reference point of height" is, for example, the ground surface.

[0154] The "floor plan information for each floor" includes, but is not limited to, the identification number FPID of each floor, the use of the areas on that floor (parking lot, store (type of store), office, etc.), the area of ​​each area, and attributes of each area by time period (residential facility, commercial facility, tourist facility, accommodation facility, etc.).

[0155] In other words, in building information (including facility information and location information), if the attributes (purpose) of the same building (facility, location) differ depending on the date, time, and time of day, the building information may be configured to specify the respective attributes for each date, time, and time.

[0156] The building information also includes two-dimensional or three-dimensional polygon information (not shown) of the building in association with the building ID.

[0157] 2D polygon information is a representation of the shape of a building or house using polygons in a GIS (geographic information system). 3D polygon information is a representation of the shape of each floor of a building or house, as well as the exterior shape of the building or house, in the height direction.

[0158] Furthermore, the specifications of the indoor information are not particularly limited, but may conform to, for example, the following "3D Indoor Geospatial Information Data Specification (draft)." https: / / www.gsi.go.jp / common / 000212582.pdf

[0159] As described in the first embodiment, the building owner or manager may register building information (such as floor plans and 2D or 3D polygon data) via the building information registration terminal 4000. Alternatively, the building information registration terminal 4000 may be configured so that visitors to the building register information such as photos of the interior of the building as building information, using a mobile terminal such as a smartphone having a photography function. For example, in the case of a smartphone, the people flow information service providing server 2000' may receive notifications from users who use terminals that have installed application software having an input format that notifies the user of the building name, number of floors, and area information (such as store name and type of store) along with the captured photos.

[0160] The people flow information service providing server 2000 ′ may be configured to store information about buildings as the map information 2314 in the storage device 2300 .

[0161] As described above, the map information 2314 is a database that stores polygon information of buildings and facilities, roads, and administrative district boundaries used by the area setting unit 2107 when specifying the boundaries of a specific area, and the building information registration terminal 4000 accepts registration of building information (including 2D or 3D polygon information) in the database. Since buildings, etc. are constantly updated, it is desirable to have a configuration that allows polygon information to be provided from outside.

[0162] It is also possible to receive design data of buildings and facilities that have not yet been started or are not completed in a specified area ("analysis target area") from the building information registration terminal 4000, and to predict and estimate the number of visitors to the buildings and facilities in the future based on this design data. In this case, for example, if the design data specifies the attributes of each floor area of ​​the buildings and facilities that have not yet been started or are not completed, the number of people staying in the analysis target area can be predicted and estimated by multiplying the number estimated from the current demographic information by a predetermined coefficient (for example, 1.3) and allocating it within the analysis target area as the expected number of people. Here, the predetermined coefficient can be configured to be determined according to, for example, the ratio of the total floor area of ​​the buildings and facilities that have not yet been started or are not completed to the total floor area of ​​the buildings and facilities in the analysis target area that have been completed.

[0163] In the above description, it is assumed that the distribution of people within a predetermined analysis target area is estimated in the following manner.

[0164] i) For a specified area, "spatial statistical data" is obtained for each specified area mesh and for each first time interval, the data being compiled based on information on mobile phone usage, etc.

[0165] ii) For people who are present in a specified area (analysis target area) during a first time interval, the Basic Survey on Social Life DB is referenced to classify the people into behavioral classification information for each second time interval that is shorter than the first time interval, and the number of people in each classification is estimated.

[0166] iii) For the area to be analyzed, the number of people by occupation for each second time interval is estimated by referring to the Ministry of Internal Affairs and Communications Labor Force Survey DB, etc.

[0167] iv) For the analysis area, the number of people by occupation type for each second time interval is apportioned based on the total floor area of ​​each area of ​​the buildings on the map and the information on the occupation types of each building, thereby estimating the distribution of people (aggregated data) for a mesh (estimated area mesh) finer than the specified area mesh of the spatial statistical data.

[0168] As described in the first embodiment, the first time interval and the second time interval may be the same.

[0169] However, this method of apportioning the number of employees does not necessarily take into account the following points:

[0170] i) For example, during the night, when the behavior is classified as sleeping, residents in the analysis area should be preferentially allocated to residential buildings, while those who are neither residents nor workers in the analysis area (transient visitors) should be preferentially allocated to accommodation facilities (e.g., hotels) in the analysis area.

[0171] ii) Similarly, during the daytime on weekdays, workers in the analysis area should be preferentially allocated to buildings having attributes such as commercial facilities and business offices.

[0172] Therefore, in the second embodiment, it is assumed that the people flow information service providing server 2000' is configured to assign an attribute of "stay type" to people who stay in the area to be analyzed during each time period, and priorities are set in advance so that the priority of the distribution of numbers of people is changed according to the attributes of the time period and location.

[0173] It should be noted that, although not limited thereto, for example, the attribute "stay type" can be acquired from demographic data.

[0174] The area location information estimation unit 2108 then assigns priority to residential attributes if the person is a resident, to business facilities (business buildings, stores in commercial facilities, etc.) if the person is an employee, and to short-term stay locations and entertainment facilities if the person is not an employee (short-term stay locations are assumed to be accommodation facilities such as hotels and inns, and entertainment facilities are assumed to be theme parks, parks, museums, various experience facilities, aquariums, etc.).

[0175] The area location information estimation unit 2108 also allocates people to locations by considering the attributes of the location for each time period. For example, if the attribute is ("resident" + behavior information of "sleeping"), it preferentially allocates to a residence, and if the attribute is ("non-resident / non-worker" + behavior information of "sleeping"), it preferentially allocates to a hotel.

[0176] That is, as explained in FIG. 26 and FIG. 27, first, "Mobile Spatial Statistics (registered trademark)" includes information on the residential area.

[0177] Here, during the de-identification process in Fig. 27, it is possible to extract and count the number of "residents" of the analysis target area and residents outside that area who regularly move to the analysis target area on weekdays (workers). It is also possible to classify "persons who are neither residents nor workers" who are in the analysis target area during a certain period of time as "temporary visitors" and count them.

[0178] In this case, a "temporary visitor" would be, for example, a tourist or shopper, so if there are entertainment or tourist facilities such as theme parks within the area being analyzed, it is possible to set it up so that priority is given to those facilities during their operating hours.

[0179] As described above, the attributes of buildings or places are registered in the map information 2314 of the life information service providing server 2000, and the area location information 2310 is set in advance with a priority of "stay type" for distribution of the attributes of buildings or places (such as residences, commercial facilities, offices, accommodation facilities, entertainment and tourist facilities, etc.).

[0180] FIG. 16 is a flowchart showing the process of estimating the number of people distribution in an analysis target area, taking into account the stay attributes.

[0181] 16, in the people flow information service providing server 2000', the area setting unit 2107 first executes a process of setting an area to be analyzed in response to an operation by a user (S102). At this time, the area setting unit 2107 also receives settings of the date, time, and time period to be analyzed from the user.

[0182] Next, the calculation device 2100 acquires spatial statistical data via the network (S110).

[0183] As mentioned above, to obtain spatial statistical data, it is possible to use "Mobile Spatial Statistics (registered trademark)" provided by NTT DoCoMo. Spatial statistical data is, for example, data on the number of people by age and sex in a given time unit (for example, 1 hour) within a mesh of a given width (for example, 500m square).

[0184] The lifestyle information estimation unit 2110 further acquires information on stay attributes from the spatial statistical data (S112).

[0185] Next, for a "predetermined area" specified by the area setting unit 2106 based on the user's designation, the lifestyle information estimation unit 2110 classifies people (whose age and gender are obtained from the spatial statistical data) who are staying in a specific area during a specific time period (for example, a certain hour) into states (behavior classification information) such as work and movement (for example, commuting) in more detailed time units (for example, 15 minutes) within this specific time period based on the spatial statistical data, with reference to the Basic Survey on Social Life database, and estimates the number of people in each category (for example, age and gender attributes and stay attributes) (S120).

[0186] Furthermore, the lifestyle information estimation unit 2110 estimates the number of employees (age and gender attributes) by occupation type for every 15 minutes in the above-mentioned specific area based on the estimated number of people (age and gender attributes, stay attributes) for each behavior category, for example, based on the Ministry of Internal Affairs and Communications Labor Force Survey database (S130).

[0187] Next, the area location information estimation unit 2108 expands (for example, proportionally allocates) the estimated number of employees by occupation for every 15 minutes (by age and gender attributes and stay attributes) to each building (facility) based on the total floor area of ​​the facilities and buildings on the map, the area allocated to the occupation of each facility and building, and the attributes of each building (facility), and estimates aggregated data of the number of people in a mesh smaller than the unit mesh of the spatial statistical data (for example, a 62.5 m mesh) (S141).

[0188] Finally, the people flow information estimation unit 2103 estimates the distribution of people's attributes within the analysis target area based on the classification and aggregated data of people's behavior estimated in the estimated area mesh that exists within the analysis target area.

[0189] In addition, when distributing the number of people in a certain mesh to each building (facility / place) according to the stay attribute, the area place information estimation unit 2108 can also calculate the excess number of people for the building (facility / place) if an upper limit is set for the number of people that the building (facility / place) can accommodate. For example, such excess number of people can be distributed with the second highest priority to roads around the building (facility / place) and major transportation stations (S150).

[0190] Next, if the area location information estimation unit 2108 has not completed the process of distributing the number of people for all types of specified stay attributes (N in S160), it returns the process to step S120, and if the area location information estimation unit 2108 has completed the process of distributing the number of people for all types of specified stay attributes (Y in S160), it ends the process.

[0191] 17 and 18 are heat maps showing the distribution of the number of people per area mesh (500 m square) within a given area, taking into account the attributes of the visitor.

[0192] Fig. 17(a) shows the distribution of all people visiting a 500m mesh, while Fig. 17(b) shows the distribution of only residents in the 500m mesh (e.g., people who regularly stay within that mesh overnight).

[0193] Figure 18(a) shows the distribution of workers (including students, for example, people who are in the same mesh regularly during the day) staying in a 500m mesh, while Figure 18(b) shows the distribution of temporary residents in a 500m mesh (people in a mesh who do not visit the mesh regularly, such as tourists or visitors from far away).

[0194] In this manner, by estimating the distribution of people within the estimated area mesh while taking into account the “stay type,” it is possible to estimate the distribution of people within the analysis target area with greater accuracy than in embodiment 1. [System using the Lifestyle Information Providing Server 2000 and People Flow Information Providing Server 2000']

[0195] FIG. 19 is a conceptual diagram showing the hierarchy of data and the hierarchy of data processing used in the lifestyle information estimating system.

[0196] FIG. 20 is a conceptual diagram showing an outline of the flow of data processing.

[0197] As shown in Figure 19, the "public domain," which is a public and open domain, includes, for example, the "urban OS" as "software that supports urban infrastructure" and the data integration platform.

[0198] In Japan, for example, the following Cabinet Office documents are publicly available: Publicly known documents: https: / / www8.cao.go.jp / cstp / stmain / a-whitepaper3_200331.pdf

[0199] Here, there are three challenges to realizing smart cities in Japan: i) reuse and horizontal deployment of services, ii) utilization of data across fields, and iii) low scalability.

[0200] i) In terms of reusing and expanding services, traditionally systems were specialized for each field or organization, which made it difficult to reuse or expand services to other regions.

[0201] ii) When it comes to utilizing data across sectors, traditional services have separate data for each sector and organization, making it difficult to build new services that span sectors.

[0202] iii) Low scalability: Conventional specialized systems have the problem that expanding functions requires large costs and effort, making it difficult to continuously and easily evolve services.

[0203] In order to address the challenges in realizing these smart cities in Japan, the City OS will be designed to have the following features: i) interoperability (connection), ii) data distribution (flow), and iii) ease of expansion (sustainability).

[0204] The "lifestyle information estimation system area" of this embodiment is conceptually configured to exist on such a foundation.

[0205] As shown in FIG. 19, in addition to the "DoCoMo Spatial Statistics (registered trademark)" as shown in FIG. 4, the lifestyle information estimation system 1000 is also expected to utilize weather data for a specific time period in a specific area obtained from a server of the Japan Meteorological Agency, "disaster risk information" obtained from the National Research Institute for Earth Science and Disaster Prevention, and the like.

[0206] When such data is stored in the above-mentioned "data lake," it is first stored as general-purpose raw data, and then finalized for a certain period of time, and stored as a "unified format for the lifestyle information estimation system (for example, unifying the unit area mesh)" as described above.

[0207] As shown in Figures 19 and 20, data in a general-purpose data format provided to the "Data Lake" may be posted from a smartphone via a smartphone application, for example. The posted data may be subjective evaluation data on the congestion situation at a specific facility in a specific location, or may be photographs or videos of the congestion situation.

[0208] Furthermore, as shown in Figures 19 and 20, above the "data lake" there is a data analysis layer, which corresponds to the data integration and analysis processing performed by the above-mentioned lifestyle information service providing server 2000 and people flow information service providing server 2000'.

[0209] The system is structured so that a section that adds some sort of evaluation to the analysis results, or collaborates with other companies on the results, and finally visualizes and presents them, exists at a higher data display level.

[0210] In particular, while spatial statistics are based on an hourly basis, the above-mentioned processing makes it possible to perform data analysis and visualization in 15-minute increments, which is almost real-time.

[0211] As shown in Figure 20, after the above-mentioned integrated analysis process is performed, facilities in the town are evaluated based on the information, and people are allocated to each facility, so the people flow distribution is created from independent information (people flow → behavior → town information), and therefore the people flow distribution changes when the "town information (general map information)" is updated. Therefore, it is possible to visualize not only current real-time information, but also people flow distribution in towns that differ from the present in the past and future.

[0212] For example, by using city information from the Edo period, we can estimate the distribution of people at that time and visualize the life of the city at that time, and by using city information from virtual worlds such as movies, anime, and games, we can estimate the distribution of people in the virtual world. Of course, it is also possible to visualize the life of a specific city in the future (e.g. Osaka City).

[0213] These analytical results can be used for urban planning, environmental optimization, energy optimization, real estate value assessment, logistics optimization, etc. For example, when assessing real estate value, it is possible to analyze and evaluate what kind of changes in population distribution may occur if a certain facility is hypothetically constructed in a certain location in the future, and this information can be added to the real estate value assessment.

[0214] One possible use case for data integration and analysis would be to distribute admission tickets to product promotional events (whether at a physical or virtual venue) via smartphone based on users' behavioral history, etc.

[0215] FIG. 21 is a diagram showing an overview of services realized by using the lifestyle information estimating system 1000.

[0216] FIG. 22 is a conceptual diagram showing an example of the service shown in FIG. 21, which is provided via a smartphone.

[0217] As shown in Figure 21, maps, people flows, various sensor data, weather data, satellite data, real estate data, and data posted via smartphones accumulated in the data lake can be used to analyze the condition of each region (artificial intelligence prediction), calculate a score for each region for specified evaluation items, and map and visualize each region.

[0218] In this case, the output of the integrated analysis platform will be provided with interfaces suitable for residents, local businesses, and local governments.

[0219] For example, residents could be encouraged to make behavioral changes through a smartphone application to improve the score for their neighborhood or area of ​​residence.

[0220] For example, as shown in Figure 22, in the real world, it is possible to think of a moving person (or the smartphone they carry and move around with) as a kind of sensor that accumulates data in a data lake via a smartphone application. By using city information posted by smartphone users (which can include not only crowding but also data on the weather, accidents, crime, etc.), it is possible to provide a location analysis platform as a service in the digital space, such as the distribution of people within walking distance, or even the distribution of people in the surrounding area, and even larger statistical data on the state of the city in the living area.

[0221] With this configuration, it is possible to collect information about the town's attractions directly from local residents, and it is also possible to encourage behavioral changes among people who can share information via smartphone (such as visiting the town).

[0222] Furthermore, by using detailed analysis reports and town simulation tools to base policy decisions and implementation effectively and efficiently on objective evidence, the government will be able to keep the cycle of town development for everyone going.

[0223] Regional businesses will be able to carry out area marketing such as store development and sales promotion based on the scores obtained from the integrated analysis platform.

[0224] FIG. 23 is a diagram showing another example of data visualization by integrated analysis.

[0225] We have explained above how the current state of a city can be displayed in real time by using an integrated analysis platform.

[0226] In this case, the types of data that can be superimposed on the map information include "distribution of the number of people (including people flow. People flow can also be shown, for example, using vectors)" and "elevation," as well as the type of use of each location within the area, such as "commercial use," "residential use," or "office use," the spatial utilization rate, and even the distribution of road maintenance conditions.

[0227] As described above, by utilizing the integrated analysis by the lifestyle information service providing server 2000 and the people flow information service providing server 2000', more precise estimations can be made regarding employment, which is an important part of a person's life, based on employment information by occupation.

[0228] In addition, by utilizing integrated analysis by the lifestyle information service providing server 2000 and the people flow information service providing server 2000', the estimated lifestyle information can be provided to the user in a form that is easily understandable to the user through visualized information such as charts.

[0229] Furthermore, by utilizing the integrated analysis by the life information service providing server 2000 and the people flow information service providing server 2000', the user can easily understand the estimated life information by relating it to a location on a map.

[0230] Furthermore, by utilizing the integrated analysis by the life information service providing server 2000 and the people flow information service providing server 2000', accurate estimation can be made for each area (62.5 m mesh) in which a person can move in one minute, for example.

[0231] Furthermore, by utilizing the integrated analysis by the life information service providing server 2000 and the people flow information service providing server 2000', it is possible to perform a time series analysis for a predetermined period of time.

[0232] Furthermore, by utilizing the integrated analysis by the life information service providing server 2000 and the people flow information service providing server 2000', it is possible to simulate life information in the past or future.

[0233] Furthermore, by utilizing the integrated analysis by the life information service providing server 2000 and the people flow information service providing server 2000', when a predetermined area location information cannot be obtained as statistical information or the like, it can be supplemented by estimation.

[0234] Furthermore, by utilizing the integrated analysis by the life information service providing server 2000 and the people flow information service providing server 2000', when certain life information cannot be obtained as statistical information or the like, it is possible to supplement it by estimation.

[0235] Furthermore, by utilizing integrated analysis by the lifestyle information service providing server 2000 and the people flow information service providing server 2000', it is possible to estimate area lifestyle information including at least information related to people flow routes based on demographic information including at least information related to the origin of movement (e.g., people commuting from home, people returning home from a restaurant, etc.).

[0236] 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 that can achieve the object of the present invention are included in the present invention.

[0237] Furthermore, for example, the above-described series of processes can be executed by hardware or software.

[0238] In other words, the functional configurations in FIGS. 1 to 23 are merely examples and are not particularly limited.

[0239] That is, it is sufficient that the information processing system is provided with a function capable of executing the above-mentioned series of processes as a whole, and the type of functional block used to realize this function is not limited to the examples in Figures 1 to 23. Furthermore, the locations of the functional blocks and databases are not particularly limited to those in Figures 1 to 23 and may be arbitrary.

Conversely, the functional blocks and databases of the user terminal may be transferred to a server or the like.

[0240] Furthermore, one functional block may be configured as a single piece of hardware, a single piece of software, or a combination of both.

[0242] The computer may be a computer implemented with dedicated hardware.

[0243] Furthermore, the computer may be a computer capable of executing various functions by installing various programs thereon, such as a server, a general-purpose smartphone, or a personal computer.

[0244] A 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 a user, etc., but also of a recording medium that is provided to a user, etc. in a state where it is pre-installed in the device main body.

[0245] In this specification, the steps of describing a program to be recorded on a recording medium include not only processes that are performed chronologically according to the order, but also processes that are not necessarily performed chronologically but are executed in parallel or individually.
