Description

  The present invention relates to a technique for displaying various information related to a map.

  In recent years, there has been a remarkable development of so-called navigation devices, not just simply searching for a route and guiding the way to the destination, but also specifying other facilities and places, other facilities related to that facility. There is known one that displays information in association with other information such as guidance (see Patent Document 1 below).

JP 2008-250383 A

  However, such a conventional apparatus has a problem that although it can display facility and guidance information, for example, historical and political related information, it can only display specific information associated in advance. For example, when searching for a route to a hospital destination, the information required by the user of the device is often different depending on whether the reason for visiting the hospital is due to a medical examination or not. It will be displayed. In addition, the displayed information needs to be associated in advance. For example, even if a new facility is opened near the destination, it is not displayed at all unless the facility is associated with the destination. However, associating a large number of facilities existing on the map without omission is troublesome.

  In addition to these problems, in the conventional information display technology using a map, it has been desired to reduce the size of the apparatus, to reduce the cost, to save resources, to facilitate manufacturing, and to improve usability.

Hereinafter, some embodiments of the present invention will be described with reference to the drawings.
<First Embodiment>
FIG. 1 is a schematic configuration diagram of a navigation system 10 according to the first embodiment. The navigation system 10 includes at least one smartphone 20 and a server 50. The navigation system 10 can perform route guidance for pedestrians and route guidance for automobiles. In the following, the navigation system 10 will be described with a focus on a configuration including at least one smartphone 20 and the server 50 as the navigation system 10. It can be realized as route guidance.

  The smartphone 20 is a multifunctional mobile phone that can be connected to the Internet. The smartphone 20 and the server 50 can be connected to each other via the Internet INT that is one of the wide area networks. The smartphone 20 is wirelessly connected to the Internet INT via the base station BS. In practice, the smartphone 20 is connected to the Internet INT via a transmission / reception antenna, a radio base station, and an exchange. The base station BS shown in FIG. 1 includes these antennas, radio base stations, and exchanges.

  As shown in FIG. 1, the server 50 includes a communication unit 52, a control unit 54, a map database 56, a relationship table 57, and a note database 58 (the database may be abbreviated as “DB”). . The control unit 54 acquires map data corresponding to the request from the smartphone 20 received by the communication unit 52 from the map database 56, and the communication unit 52 distributes the map data to the smartphone 20 via the Internet INT and the base station BS. Further, the control unit 54 performs route search in response to the request from the smartphone 20 received by the communication unit 52, and the communication unit 52 distributes the searched route information to the smartphone 20 via the Internet INT and the base station BS. Furthermore, the control unit 54 refers to the relationship table 57 and the note database 58 based on the information received from the smartphone 20 and specifies information (hereinafter also referred to as “note”) to be displayed on the smartphone 20. The data is output to the smartphone 20 via the Internet INT and the base station BS. The relation table 57 stores the main facility information of the main facility, the sub-facility information of the sub-facility, and the conditions connecting them. In addition, the note database 58 stores information related to facilities in each region so as to be searchable. The information included in the annotation database 58 is a facility name, a facility type (classification), and a facility-related note. The process for displaying the note on the smartphone 20 will be described in detail later.

  The smartphone 20 includes a main control unit 22, a communication unit 32, a communication control unit 34, a touch panel 36, a display unit 38, an audio output unit 40, and a GPS receiver 42. The main control unit 22 includes a CPU 24, a RAM 26, and a ROM 28. The main control unit 22 controls other devices provided in the smartphone 20. The RAM 26 receives map data, route information, and annotation information distributed from the server 50, and temporarily stores them. The ROM 28 stores a program executed by the CPU 24. This program is for realizing departure processing, route guidance processing, exchange with the server, display of information received from the server, and the like. The ROM 28 is a flash ROM, and can store map data and route information distributed from the server 50 even when the power is turned off. The communication unit 32 is a circuit for performing data communication or voice communication by the base station BS or by wireless LAN connection. The communication unit 32 operates to access the server 50 via the Internet INT and the base station BS and acquire map data, route information, and note information. The communication control unit 34 is a circuit that performs incoming calls and calls for voice calls, conversion between voice signals and electrical signals, and the like. The smartphone 20 also functions as a telephone by including the communication unit 32 and the communication control unit 34.

  The audio output unit 40 is a speaker that outputs audio. The GPS receiver 42 is a device for acquiring information indicating the self-position of the smartphone 20 by receiving GPS signals transmitted from a GPS satellite and an indoor GPS transmitter. The touch panel 36 functions as an input / output interface using a liquid crystal screen. The touch panel 36 supports multi-touch input, and acquires the position coordinates at which the user's finger, a dedicated pen, or the like touches the liquid crystal screen and inputs the position coordinates to the main control unit 22. The main control unit 22 determines a user instruction based on the input position coordinates, and executes processing corresponding to the determined instruction.

  The map database 56 stores map data. The map data includes feature data that is data representing features such as roads and facilities that are the background of the map, and network information that is composed of nodes and links and is used for route search. The features can include anything that exists on the surface of the earth, such as buildings, facilities, parks, mountains, rivers, and railway lines. Of course, only a part of it may be treated as a “feature”. These features are stored on the map database 56 as an ID for identifying the feature, information on its position, and shape data, and further, information such as the name and type of the feature is associated with the ID. Attached.

  FIG. 2 is a flowchart showing an outline of navigation processing including route search performed by the navigation system 10. This process is started with the process on the smartphone 20 side as a trigger. In the following description, when the smartphone 20 is generalized, it may be referred to as a “terminal” for the server.

  When performing a route search, the user activates dedicated application software on the smartphone 20 side and inputs a route search condition (step S100). The conditions input on the smartphone 20 include the departure place of the route to be searched, the arrival place, the means used to reach the arrival place (transport means such as car, train, walking, etc. Other methods may be used and other conditions may be considered. Other conditions include, for example, the user's gender, age, or the like, or the purpose and reason for the action when searching for a route and acting. These other conditions may be input or may not be input. Further, information registered in advance in the smartphone 20 may be used for the sex and age of the user. The purpose and reason of the action can be estimated from other information as described later, or can be directly input by the user. Note that the “arrival place” is sometimes referred to as a “destination” in a route search or the like, but is handled in the same way in the route search or behavior estimation or prediction described later. The word “arrival place” is also used in the meaning.

  When the input of these conditions is completed, the user taps a “Send” button or the like displayed on the screen, and performs a process of transmitting the input conditions to the server (step S110). Data transmission from the smartphone 20 is performed from the base station BS to the server 50 via the Internet INT. When the server 50 receives the transmitted data (step S200), the server 50 performs a route search process in accordance with the above conditions included in the data (step S210). In the route search processing, the route from the departure point to the arrival point input by the user is well known based on route information (link and node information indicating road connection) recorded in the map database 56 of the server 50. The search process is based on the Dijkstra algorithm. Since this route search process is a well-known one, a detailed description thereof will be omitted. In the route search process, the route to be searched differs depending on whether the moving means is a car or a walk. Furthermore, depending on the gender of the user, search for a safer route when walking or walking and at night (if the user is a woman or younger than a certain age), or search for a short route with a large difference in elevation. Various route searches such as (when the user is male or within a predetermined age range) can be performed according to the other input conditions.

  When the server 50 performs the route search process, the server 50 next performs a note specifying process (step S300). Although details of the note specifying process will be described later, this process is a process for specifying information to be presented to the user (hereinafter also referred to as note information) regarding the facility related to the searched route. After performing the above route search and identification of note information, the server 50 transmits the results of these processes to the smartphone 20 that is a terminal (step S400). If the server 50 can confirm that the transmitted data is received on the terminal side, the server 50 exits to “END” and ends the process.

  The smartphone 20 receives the transmission from the server 50 (step S120), and repeats the process of displaying the received information (step S130) until the route guidance ends (step S140). The end of the route guidance is a case where it is determined that the user of the smartphone 20 ends the route guidance application software, ends the route guidance in the application software, or arrives at the arrival place. Whether or not the vehicle has arrived can be determined from information on the current location received from the GPS receiver 42 built in the smartphone 20. When the smartphone 20 determines that the route guidance has ended (step S140), the smartphone 20 exits to "END" and ends the terminal-side processing routine.

  Next, the note specifying process (step S300) will be described with reference to FIG. In the present embodiment, the processing for specifying the annotation information is executed by the server 50. When this processing routine is started, the control unit 54 of the server 50 first performs a process of inputting a departure place, an arrival place, and other conditions received from the smartphone 20 as a terminal (step S310). Next, a process for estimating the purpose of the action from the received information is performed (step S320). Various methods can be considered for the action estimation process. In the first embodiment, the user directly inputs the action. That is, when the user inputs the route search conditions on the smartphone 20 side (FIG. 2, step S100), the purpose of the route search is directly specified, for example, “visit” or “going to hospital”. . For this designation, the user may directly input a character string, or the route search application software may prepare an option, and the user may select from the option.

  Next, the control part 54 performs the process which acquires a facility kind from a user's action purpose (it has input in this embodiment) (step S330). This process is performed by referring to the master-slave relationship table. An example of the master-slave relationship table is shown in FIG. As illustrated in FIG. 4, this table includes main facility information, conditions, and subsidiary facility information. Here, the main facility corresponds to the main feature, and the main facility information includes the classification (type) of the facility and whether the facility corresponds to the departure place or the arrival place. Contains information. The conditions include information on who is applied, information on what action is being performed, information on what the means is, and information on which time is applied. The subsidiary facility corresponds to a subsidiary feature, and the subsidiary facility information includes a classification (type) of the facility and a display condition. In FIG. 4, “−” indicates a common condition. In other words, for example, the condition “who” corresponds to “female”, “male”, and the like, and there is a common condition that does not distinguish between these, and the latter is displayed as “−”.

  Of course, the main facility information, conditions, and subsidiary facility information may include information and conditions other than these information and conditions. For example, the “condition” may include distinction such as usage frequency, weather conditions, and seasons. Alternatively, the “condition” may not include one or more conditions of information other than behavior. The “main facility information” and “subordinate facility information” may include quality evaluation such as facility grade, facility scale (large, medium, and small). Alternatively, “main facility information” and “subordinate facility information” may be only the classification (type) of facility.

  Specifically, the process of acquiring the facility type is performed as follows in the present embodiment. First, information input by the user when searching for a route is specified. The feature existing there is specified from the information of the departure place and the arrival place inputted by the user. The identification of the feature may be directly specified as a part of the route search condition, or the location may be determined by referring to the map database 56 from the place of departure or arrival (latitude, longitude). It is also possible to identify as a facility in For example, as a route search, “present hospital” is designated from “XX hospital”, “car” is input as the moving means, and “visit” is input as the purpose. For a specific facility such as “XX hospital”, the classification of the main facility “hospital” is taken out of it, and the master-slave relationship table (FIG. 4) is referred to. There are many items in the master-slave relationship table even at the same hospital. Therefore, the corresponding master-detail relationship is specified with reference to the action purpose information.

  In this example, since the arrival place is “hospital”, the transportation means is “car”, and the action is “visit”, the relationship shown as ★ 1 to ★ 3 in the master-slave relationship table shown in FIG. 4 is found. become. As a result, in the relationship of ★ 1, the information “parking lot” and “surrounding” is obtained as a subsidiary facility, and in the relationship of ★ 2, the information “floral shop” and “common” are obtained as a subsidiary facility. In the relationship, information such as “fruits and vegetables” and “common” can be obtained as subordinate facilities. FIG. 5 exemplifies a list of relationships thus extracted.

  After the above relationship is obtained by the facility type acquisition process, an area search based on the facility type is performed (step S340). This process is a process of searching the note database 58 for whether or not there is a subsidiary facility belonging to the relationship shown in FIG. 5 in the area including the route from the departure point to the arrival point. In the note database 58, information on various facilities in the area is accumulated in the form of facility name, type (classification), and note information. Notes information can be acquired. Therefore, next, processing for specifying the annotation information is performed (step S360), and after that, “NEXT” is skipped and the processing is terminated.

The server 50 is transmitting the note information specified by the said process to the smart phone 20 (FIG. 2, step S400). When receiving this (step S120), the smartphone 20 executes display processing (step S130). Details of this display processing are shown in FIG. When the smartphone 20 receives information from the server 50, the smartphone 20 first performs a process of storing the information (step S131). Specifically, the route information and note information received from the server 50 are stored in the RAM 26. Next, according to the received route search information, the following processing is repeatedly executed from the departure place (step S132) to the arrival place (step S136).
(1) Processing for drawing a map and a route (step S133)
(2) Processing for determining whether there is a facility in the drawn range (step S134)
(3) When there is a facility, processing for displaying or highlighting the note information of the facility (step S135)

  In these processes, as shown in FIG. 7A, a map including the departure place is displayed on the display unit 38 of the smartphone 20, and a route BB that is guided over the map is displayed. If there is a corresponding facility (for example, a parking lot PK around the route) within the range, this corresponds to displaying or highlighting the annotation information (for example, the facility name or available time) INF of the facility. For the subsidiary facility to be displayed, if the display mode is “route”, the note information of the facility facing the road corresponding to the searched route is displayed. If the display mode is “periphery”, the searched road Even if not facing, the note information of facilities within a certain range from the road, for example, within 50 meters, is displayed or emphasized. FIG. 7A shows an example of a normal route guidance display in which no note information is displayed. On the other hand, FIG. 7 (B) shows an example when the note information is displayed. In FIG. 7B, a parking lot facing the route, a flower shop within a predetermined distance from the route, and the like are displayed.

  The drawing of the map and the display of the route and the note information are repeated until the user of the smartphone 20 arrives at the arrival place (steps S132 to S136). If it is determined from the information from the GPS receiver 42 that the vehicle has arrived at the arrival location, it is next determined whether there is a facility at the arrival location (step S137). Step S138), and then the process goes to “END” to end the process. If there is a hospital at the arrival place, the note information such as the hospital facility name is displayed. Of course, if there is a facility that has found a master-slave relationship with the facility at the destination, it may be displayed. FIG. 7C shows an example in which the visitable time of the hospital which is the arriving facility is specified as the note information with reference to the behavior “visit” and displayed.

  In the navigation system 10 according to the first embodiment described above, when the route guidance is performed by the smartphone 20, the facility necessary for visiting the facility (here, the hospital) at the arrival point of the route guidance based on the inputted action purpose. Can be identified as a subordinate facility and displayed with a map and route. For this reason, the user of the smartphone 20 who wants to perform the “visit” action purchases flowers by a florist during the visit as well as information on the parking lot necessary for the visit, It is easy to take it with you. The smartphone 20 does not display all of the many facilities existing in the area where the route is displayed, but displays only the facilities according to the user's behavior, so that the processing load is light and easy to see. Can be provided. Even if only the facilities related to the hospital, which is the main facility, are displayed, if the purpose of action is not taken into account, as shown in FIG. It will be displayed. In the navigation system 10 of the first embodiment, it is possible to suppress the display of notes of such facilities that are less important for the purpose of action, and to make the display easy to see.

<Modification>
Next, a modification of the first embodiment will be described. In the first embodiment described above, the user directly inputs the purpose of the action in the action purpose estimation process of the user (FIG. 3, step S320). On the other hand, in the modification of the first embodiment, the user does not input the action purpose, and the smartphone 20 or the server 50 estimates this. FIG. 8 is a flowchart showing a behavior purpose estimation processing routine. This process is performed by the server 50 in the modification described below, but may be performed on the terminal side such as the smartphone 20 as long as data can be accumulated.

  When the behavior purpose estimation processing routine is started, it is first determined whether or not the behavior purpose has been input (step S321). If the user has already input the purpose of action by manual input or the like, nothing is done and the process is terminated by exiting to “NEXT”. If the action purpose is not input, the facility type of the arrival place input in the route search designation is first acquired (step S322). If the arrival place is designated as position coordinates such as latitude and longitude, the facility existing at the latitude and longitude is acquired from the map database 56 or the like. Of course, it is also possible to make an inquiry to a dedicated database that stores facilities. As a result, for example, it is assumed that the facility type “hospital” has been acquired.

  First, the type of facility is determined (step S323). There are many types of facilities registered in advance, such as hospitals, supermarkets, schools, and so on. First of all, it is classified into categories such as medical facilities, commercial facilities, educational facilities, etc., and then classified according to scale, such as “general hospital”, “special hospital”, “practitioner”, etc. The type may be specified in the form of classification according to the medical field such as “Dermatology”.

  If it is determined that the facility at the arrival place is “hospital”, it is determined whether or not the hospital has been visited in the past (step S324). The history of past visits can be known by referring to past route search data. Alternatively, past visited places may be stored in the form of a database and judged by referring to this. If a visit has been made in the past, the next visit frequency is determined (step S325). The frequency of visits is determined as “daily” or “other than that”. If the visit is “every day”, the action is likely to be commuting, so the action purpose is set to “commuting” (step S326). “Everyday” may be set to be every weekday from Monday to Friday, or may be set to 4 days (or 5 days or more) per week.

  “Other than that” means other than “every day”, so for example, if the visit is less than 3 days a week, the determination is “other than that”. In this case, since “commuting” is not recognized and “visit” is not considered, the action purpose is set to “going to hospital” (step S327).

  On the other hand, if it is determined that the user has visited in the past (step S324) is “none” (not visited), then the distance from the home is determined (step S328). Since the home is normally stored in the smartphone 20, the distance from the coordinates of the home to the coordinates of the current location is determined. For example, if this distance is 1 km or less, it is judged as “close”, and if it is farther, it is judged as “far”. This distance may be increased or decreased depending on, for example, one or a combination of the user's age, sex, moving means, and the like. For example, if it is 60 years of age or older and walking, it is judged as “close” up to 500 meters. Of course, the determination distance may be set by the person himself / herself.

  If it is determined that the distance from the home is short, the behavioral purpose is set to “visit” (step S327). This is not every day, but the judgment results are the same as when visiting the same hospital repeatedly. On the other hand, if it is determined that the user is far from home, the action purpose is set to “visit” (step S329). This is because the first visit to a hospital far from home is likely to be a “visit” or “first visit”. Instead of the distance from the home, it may be determined based on the scale of the hospital, such as whether the arrival hospital is a “practitioner” or a “general hospital”. This is because it is hard to imagine a case of visiting a “practitioner”. Further, by combining this determination with the distance from the home, “visit” is set for a general hospital near the home, and “visit” is set for a general hospital far from the home. After the above processing (steps S326, S327, and S329), the processing routine is terminated after exiting to “NEXT”.

  According to the modification described above, the user's purpose of action can be estimated from the type of facility at the arrival place and the past visit history of the user. The estimated action purpose is used in referring to the relationship table in the facility type acquisition (FIG. 3, step S330) in the note specifying process. As a result, even if the user does not input his / her action purpose, the facility (note) along the action purpose is displayed together with the map in the route guidance from the server 50. Therefore, the user can obtain information necessary for the purpose of action, and if it is “visiting”, the user can easily perform actions such as stopping at a florist or finding a necessary parking lot and parking.

  Such behavioral purpose estimation can also be performed using the type of arrival point, departure point or route of the facility. For example, if the arrival place is a hotel and the transportation means is on foot, it is possible to estimate “sightseeing”. Alternatively, if the departure place is a school and the means of transportation is a car or railroad and the time is after the evening, it may be determined that the purpose of the action is “going home”. Also, if the arrival location is irregular at night in the stadium, the behavioral purpose is determined as “watching sports”, and if it is regularly visited in the daytime, the behavioral purpose is determined as “sports practice”. It is also possible to do.

  An example of the relationship between such facilities and behavioral purposes is shown in FIG. Other possible combinations of facility types and behavioral purposes include ceremonial halls, department stores, convenience stores, racetracks / bicycle races / boat races, restaurants, viewing facilities (towers, etc.), gas stations, service areas, stations・ Various facilities such as terminals such as ports and airports, parks, hot springs, mountains, beaches and lakes can be considered. The frequency of visits is daily (morning and evening), daily, daily (weekdays only), weekly, every weekend, every month, every year, at regular intervals, for the first time, at the beginning of the year, at the beginning of the month, at the end of the month, at the end of the month, every season Various frequencies are conceivable. In general, commuting, attending school, attending school, practice, etc. can be considered for daily life, and for weekly and monthly events, going to hospital, practice, etc. can be considered as behavioral purposes. Visiting, sightseeing, etc. are possible. As the distance considered in the estimation of the behavioral purpose, in addition to the distance from the home, the distance from the station, the distance from the current location to the arrival location, the distance from the departure location to the current location, and the like can be considered. Furthermore, as the moving means to be considered in the estimation of the behavioral purpose, types such as walking, bicycle, motorcycle, automobile, bus, railway, ship, and airplane can be considered. Even on the same train, normal, limited express, night light, sleeper car, etc. may be distinguished. Moreover, as time to consider in the estimation of the behavioral purpose, various time categories such as morning / afternoon, daytime / nighttime, noon, evening / half-night / midnight can be considered. In addition, the user's classification (gender, age classification (old and young), etc.), presence / absence of disability, main language used, etc. may be used for estimating the purpose of behavior. , Smart phones, PDAs, pads, notebook computers, vehicle navigation devices, portable navigation devices), which are the same in the second and third embodiments and modifications described below. It is.

Second Embodiment
Next, a second embodiment of the present invention will be described. The navigation system 10 of the second embodiment has the same system configuration (see FIG. 1) as that of the first embodiment. In the second embodiment, in the navigation system 10, the normal smartphone 20 and the server 50 on the terminal side execute the process illustrated in FIG. The navigation system 10 of the present embodiment predicts the behavior of the user of the smartphone 20 that is a terminal, and displays necessary information (note) on the display of the smartphone 20. Hereinafter, this process will be described.

  The process illustrated in FIG. 10 is executed as one of application software in the smartphone 20. First, on the smartphone 20 side, personal information of the user is transmitted (step T100). The personal information is information such as the user's age, sex, and home position. Following this information, the user's location (current position) is transmitted (step T110). Thereafter, the smartphone 20 waits for transmission from the server 50, receives necessary information from the server 50 (step T120), performs a process of displaying the information (step T130), and ends the application software (step T140). The processes in steps T100 to T130 described above are repeated.

  The server 50 that has received the transmission of the personal information and the location information from the smartphone 20 that is a terminal receives these pieces of information (steps T200 and T205), and performs a process of predicting the behavior of the user of the smartphone 20. (Step T300). Details of the behavior prediction process will be described later. When the server 50 predicts the user's behavior in this manner, the server 50 then refers to the master-slave relationship table and performs processing for specifying the type of the corresponding slave facility (step T400), and within the current location area of the user. Whether there is a corresponding type of facility is searched (step T410). If there is a corresponding facility, a note regarding the facility is specified (step T420), and this is transmitted to the smartphone 20 (step T500).

  In this way, since the server 50 transmits a note of the facility specified by predicting the user's behavior in the area where the user is located, to the smartphone 20, the smartphone 20 performs the display processing routine described above. , Display the note of this facility. Specifically, the corresponding facility name is displayed or the facility name is highlighted. The details of the behavior prediction process (step T300) will be described next. FIG. 11 is a flowchart showing an action prediction processing routine.

  When this process is started, a process for specifying the personal information of the user and the current time is first performed (step T310), and a process for specifying the current position of the user is further performed (step T320). These pieces of information are information transmitted from the smartphone 20 and are stored in the memory in the server 50. Next, the server 50 determines whether or not an arrival place has already been set (step T325). In the navigation system 10 according to the second embodiment, the application software on the smartphone 20 side is merely activated and does not require the user to input the arrival place, so that the arrival place is not normally set. Therefore, the determination at step T325 is normally “NO”.

  If the destination is not set, in the behavior prediction described below, in order to set the search condition to “departure”, the process of setting “departure” as departure or arrival is performed. (Step T330). Next, it is determined whether or not the current position is far from home (step T335). The position of the home is included in the personal information received from the smartphone 20, and the current location is also received from the smartphone 20. Therefore, it can be easily determined whether the current location is far from the home. Note that the criterion for determining that the person is far from home is set in accordance with the behavior prediction classification. Here, it is determined that the user is out of the living area from home (far) or in the living area (close). Specifically, the case where the distance is more than 10 kilometers from home is determined to be “far”. Yes. The living area varies depending on the individual, and also depends on whether it is a city dweller (generally living area is wide) or a rural area dweller. Therefore, it is possible to change the determination criteria based on the personal information received from the smartphone 20. Further, the criteria for judgment may be learned according to the daily action range. Of course, it is not limited to two-step judgments that are far / close, but it can be a “distance” that is completely out of the living area and has a high possibility of sightseeing, etc. It is possible to divide it into “medium distance” and “short distance” that can be recognized as a living area.

  If it is far from the home, the current position is set to “far” from the home (step T340). If it cannot be determined to be far, the current position is set to “close” (step T350). Next, a process for referring to the behavior prediction table is performed using the above settings (step T360). As a result of referring to the behavior prediction table, the behavior is predicted and acquired (step T370). The predicted action is used in the process (step T410) of searching for the type of the slave facility with reference to the master-slave relationship table in FIG. The behavior prediction table and its reference method will be described later. After acquiring the action, the process exits from “NEXT” and ends this processing routine.

  The behavior prediction processing routine shown in FIG. 11 is based on the premise that the destination is not set in the application software on the smartphone 20, but the user can also input the destination on the smartphone 20 side. It is. In such a case, the arrival place is set. In this case, the determination in step T325 is “YES”, and the process moves to step T380. When the arrival place is input, the behavior may be estimated by the behavior estimation process (see FIG. 8) already described. The process of steps T310 to T370 shown in FIG. 11 corresponds to a process of predicting the behavior of the user of the smartphone 20 while temporarily setting the current position as the departure place when the arrival place is not set. doing.

  The behavior prediction table (FIG. 12) and behavior prediction performed with reference to this will be described. FIG. 12 is an explanatory diagram for explaining the flow of processing centering on the behavior prediction table. In the server 50 and the smartphone 20, the user's actions after the application software in the second embodiment is started are accumulated. As shown in the # column, the user's behavior is as follows: 1. When the time when the user stops the behavior is 5 minutes or more, as shown in the # column. Accumulated in order. The reason why the action stop time is set to 5 minutes is to exclude, for example, a case where a car or a bus stops due to a signal wait or a train stops at a station. Of course, since the separation of actions is convenient, the determination time may be changed to either long or short, or the time may be determined by the moving means. Or it is good also as what judges by the time after a user enters in a facility until it leaves. In this case, a stop such as waiting for a signal on the road is not included, so that it is possible to more clearly determine an action break.

  In the example shown in FIG. The behavior is that the user is in front of the station away from home during the morning hours. In such a case, based on the conditions such as time zone, far from home, and in front of the station, it is possible to predict the action of “eating breakfast” as the next action of the user and to predict “walking” as the moving means. The prediction of the next action is performed by preparing a table for predicting the next action from the condition of the user's action and referring to this table. In this embodiment, the conditions for referring to the behavior prediction table are “time (morning, morning, noon, afternoon, evening, night, midnight, midnight)”, “far and near from home (far, close)”, “Types of facilities staying for a predetermined time or longer (restaurants, transportation stations, sightseeing spots, accommodation facilities, etc.)” and “staying time (arrivals, staying more than 1 hour, staying less than 1 hour, etc.)”. Of course, conditions other than these conditions, for example, “behavioral means (car, train, airplane, walk, etc.)” and “user classification (gender, age group, etc.)” may also be used. Alternatively, the behavior may be predicted by limiting to one or a plurality of these conditions or selecting an arbitrary item. If there is nothing in the behavior prediction table, the user's next behavior cannot be predicted. For example, in FIG. This behavior is that the user has spent a predetermined time in a facility classified as a restaurant, and no items that meet this condition are prepared in the behavior prediction table. Therefore, the next behavior prediction is “unpredictable”.

  In the second embodiment, an action for referring to the master-slave relationship table is extracted from the result of predicting the action (for example, “eating breakfast”). This is shown at the right end of FIG. FIG. 13 shows an example of the master-slave relationship table used in the second embodiment. As shown in the figure, in this master-slave relationship table, the action is divided into “eat” and “eating breakfast” “ It is not divided by details such as “eat lunch” or “eat dinner”. For this reason, in the behavior prediction table shown in FIG. 12, once a detailed behavior of “eat breakfast” is predicted, the behavior is adjusted according to the master-slave relationship table. Of course, if the master-slave relationship table classifies the master-slave relationship with details such as “eating breakfast”, it can be used as it is.

  After specifying the behavior to refer to the master-slave relationship table in this way, when referring to the master-slave relationship table shown in FIG. 13, the personal information received from the smartphone 20, information such as distance / near from home, Means (information such as walking and buses) are also used. It has already been explained that departure / arrival is set to “departure”. By using these pieces of information and referring to the master-slave relationship table (FIG. 13), for example, action numbers 1. Is found as the corresponding relationship in the column A1. That is, the classification “restaurant” is specified as the type of subordinate facility. Next, referring to the note database 58, the facility that is classified as a restaurant is searched for the original in the area displayed on the display unit 38 of the smartphone 20, and the store name, the note, etc. are specified. (FIG. 10, steps T400, T410, T420). A note such as the specified facility name is transmitted to the smartphone 20 and displayed (steps T120 and T130 in FIG. 10). When the behavior cannot be predicted, the master-slave relationship table cannot be referred to, so that the slave facility is not specified and normal display is performed.

  An example of the display performed on the smartphone 20 side as a result of the processing in the second embodiment will be described. FIG. 14 is an explanatory diagram illustrating a display example. Number 1 in FIG. As shown in FIG. 3, when the user is in front of the station and the next behavior prediction is “eating breakfast”, the display unit 38 of the smartphone 20 displays a map of the area where the user is located, The current position (●) of the user is displayed on the map, and the next action is predicted, and several facilities corresponding to restaurants are displayed as subordinate facilities related to eating breakfast. This corresponds to the result of searching the column A1 in the table shown in FIG. In FIG. 14A, specifically, Y gyudon store and M food are displayed from the facilities corresponding to “restaurant”. These stores are registered as facilities existing in this area with the facility classification “restaurant” in the note database 58. Since the facility for predicting the behavior of the user is “walking”, the facility is limited to two from the location close to the current location. Of course, the number of facilities to be displayed may be further increased, or may be narrowed down according to conditions such as within 500 meters from the current location. If the condition is met, all facilities in the area may be displayed.

  14A, when the user goes to Y Gyudon to eat breakfast, the display changes as shown in FIG. 14B. This is a standard display that does not specifically indicate facility notes. Next, when the user is at a bus stop called “Louburu Bus Stop”, the server 50 determines that he / she is going to sightseeing, and displays tourist facilities near the bus route from this bus stop. This corresponds to the result of searching the column A2 in the table of FIG. That is, “Aoba Castle”, “Sendai City Museum”, and “Miyagi Prefectural Gokoku Shrine” corresponding to “Sightseeing facilities (near the bus route)” in the area displayed on the display unit 38 are displayed on the map. Of these, “Sendai City Museum” and “Miyagi Prefectural Gokoku Shrine” are the names of the facilities originally displayed on the map, and are therefore displayed in a highlighted manner surrounded by a frame. FIG. 14C shows a state where the user has moved to one of the displayed facilities.

  When the user moves to “Aoba Castle”, the server 50 searches the master-slave related table based on the information that the user is in a tourist-related facility and is in the daytime, and the movement from here is on foot. A restaurant (specialty) is specified as the type of facility. This is a result of searching the column A3 of the table of FIG. As a result, a note such as a facility name of a facility that can eat and drink local specialties at restaurants in the area displayed on the display unit 38 of the smartphone 20 is displayed. The “beef tongue shop” and “Zunda coffee shop” in FIG. 14C correspond to this. For simplification of illustration, it should be noted that FIG. 14C shows both the search result in the column A2 and the search result in the column A3. From the state shown in FIG. 14 (C), when the user moves to “Gyutanya” and has lunch, the user predicts the behavior to further sightseeing, and the column A4 in FIG. Tourist facilities will continue to be displayed. A display example at this time is shown in FIG.

  As described above, in the second embodiment, when the user of the smartphone 20 activates the dedicated application software, the current position and time of the user are not particularly input without entering the destination of movement. The information is used to predict the user's next action, identify the type of subordinate facility in accordance with this action, search for a facility that falls under this type, and note the user's name, etc. It can display on the display part 38 sequentially according to action. For this reason, the user will be displayed with the facility according to his / her action purpose on the display part 38 of the smart phone 20, and can enjoy high convenience. In addition, as a note of the displayed facility, only the facility name is used in the above embodiment, but in addition to the facility name, business hours, guidance to the store, recommended menu (product), reviews from other users ( (Review) etc. may be displayed. When the terminal used by the user has a large display screen such as a tablet terminal or a notebook computer larger than the smartphone 20, displaying such abundant notation further enhances the convenience for the user. To what extent these notes are displayed may be specified by the user, or may be automatically set by learning the user's personal information or past display examples.

<Third Embodiment>
Next, a third embodiment of the present invention will be described. FIG. 15 is a flowchart showing an outline of processing in the third embodiment. The third embodiment is realized by the same hardware configuration and the same system configuration as those of the second embodiment. Therefore, only the differences in FIG. 15 will be described. On the smartphone 20 side, which is a terminal, first, a display range designated by the user is transmitted (step U90). The display range of the map displayed by the user on his / her smartphone 20 is transmitted. Subsequent processing on the smartphone 20 side is the same as in the second embodiment. On the other hand, the server 50 receives the display range information transmitted from the smartphone 20 (step U190), and then receives the personal information and the location information transmitted from the smartphone 20 side as in the second embodiment ( Steps U200 and U205), as a process unique to the third embodiment, executes a process (Step U300) of extracting note information of facilities in the area corresponding to the display range transmitted from the smartphone 20. After that, as in the second embodiment, note information is specified (step U420) and transmitted to the smartphone 20 side (step U500).

  FIG. 16 is a flowchart showing the annotation information extraction process for facilities in the area executed in the server 50. When this process is started, first, a process for specifying a facility in the area is performed (step U310). The facilities in the area are all facilities existing in the area (area) displayed on the display unit 38 of the smartphone 20. The facilities include features such as parks as already described. The area currently displayed on the smartphone 20 is exchanged as a part of personal information. When one facility is specified, the processing described below is executed, and the facilities are sequentially changed to perform processing for all the facilities in the area. However, the facility to be processed may be specified at random. However, it may be performed for each facility of the same type. Or you may carry out in order from the facility near the present position. In the present embodiment, it is assumed that the display is sequentially performed from the upper left of the displayed area (north is the northwest corner in the map above) to the lower right (the southeast corner).

When one of the facilities in the area is specified, the master-slave relationship table is then referred to for this facility (step U320). An example of the master-slave relationship table in the third embodiment is shown in FIG. The master-slave relationship table is searched to determine whether the facility specified in step U310 corresponds to a slave facility in the master-slave relationship table (step U325). This determination is made as follows.
(A) The type of the facility specified in step U310 (for example, “●● flower shop”) is determined, and the subordinate facility column of the master-detail relationship table is searched.
(B) If the facility is “● florist”, it corresponds to a florist, so a column in which the type of the subsidiary facility is “florist” is found.
(C) Determine whether the florist satisfies the found master-slave relationship. In other words, it is determined whether or not the flower shop is within 500 meters (m) from the hospital facility.
(D) If this condition is met, it is judged as “corresponding to a subordinate facility”.

  In the present embodiment, the above processing is performed for all master-slave relationships. For this reason, ●● Ikebana stores fall within 500m from the izakaya. Therefore, all these conditions are examined, and if there are applicable conditions, all the scores in that case are acquired and totaled (step U330). The score is illustrated at the right end of the master-slave relationship table of FIG. ●● For flower shops, it is determined that the above two conditions are satisfied, and the total score is 80 + 20 = 100.

  In this way, the process of determining the score of the target facility is performed (step U340). The score of the target facility is the value added in Step U330. Next, it is determined whether or not the facility note (in this case, the facility name) overlaps with other notes identified so far (step U350). If there is a facility whose score is calculated before the target facility in the area, when the facility name is displayed, the facilities may overlap as the same type. In such a case, it is determined whether the score of the target facility is higher than the score of other facilities (step U360). If the score is higher, the target facility is determined as a facility to display (step U380). If the other facility is higher, it is not selected as a facility for displaying the target facility (step U370).

  Thereafter, it is determined whether or not the above processing has been completed for all the facilities in the area (step U390). If there are any unprocessed facilities remaining in the area, the process returns to step U310 to repeat the processing. When the above process is completed for all facilities, the process exits to “NEXT” and ends this process routine.

In the navigation system 10 according to the third embodiment described above, the display unit 38 is an area where the user is located only by starting dedicated application software on the smartphone 20 without performing a route search or the like. And a predetermined facility name (note) are displayed on the map. This is illustrated in FIG. In the third embodiment, it is assumed that there are, for example, two florist shops T1 and T2 in the displayed area (see FIG. 18A). One of the two florist stores, ●● florist store T1, is assumed to satisfy a plurality of conditions in the master-slave relationship table (FIG. 17). For example,
(1) Within 500 meters from the hospital, score 80
(2) Within 500 meters from the wedding hall, score 60
(3) Within 500 meters from the pub, score 20
, The total score is 160.

  In contrast, another florist shop in the area, ▲▲ Florist shop T2, in the master-slave relationship table (FIG. 17), if only the condition within 500 meters from the hospital is met, the score is 80. It becomes. For this reason, as shown in FIG. 18B, the florist store where the facility name (note) is actually displayed is only the ●● florist store T1, and the facility name of ▲▲ florist store T2 is not displayed. As a result, the probability that the user is located in the area along with what kind of action purpose is estimated for each facility, and information useful for the user who is located along any action purpose Can be displayed on the display unit 38 of the smartphone 20.

  In the above embodiment, the same type of facility is displayed with the highest score. However, as long as the facility name and other notes are not overlapped, all the facilities that have obtained scores in the area are displayed. You may make it do. If the display overlaps and it is difficult to see, only the one with the higher score may be displayed, or the other display position or the size of the note may be adjusted. In addition, it is not displayed in the display example shown in FIG. 18B whether the master-slave relationship is established with which facility, but the score is obtained as shown in FIG. 18A. The obtained master-slave relationship may be displayed. Such display is not always performed, but may be displayed for a certain period of time when a facility whose facility name is displayed is tapped. At this time, it is also useful to display the note (facility name) of the main facility together. Further, for a facility that the user has visited in the past, the score may be increased to make it easier to display.

<Other Embodiments (Modifications)>
-Modification A:
In each of the above embodiments, statistical information may be used for behavior prediction. For example, in the second embodiment, when the server 50 obtains the user's personal information, for example, when a single man in his 30s is going to have lunch at a tourist spot, it is statistically most likely to go You may employ | adopt the form said to display from a store (specialties). In 3rd Embodiment, it is good also as a structure which refers to a statistical process from a user's personal information, and increases the score of an institution most easily.

-Modification B:
The master-slave relationship table used in each of the above embodiments is optimized according to the purpose. However, a single master-slave relationship table may be created and a part thereof may be used according to the purpose. . It is also possible to prepare a master-slave relationship table for each user, learn based on the user's behavior, prioritize relationships with high usage frequency, or increase the score. Or conversely, it is also conceivable to prepare a master-slave relationship table common to users and tune the master-slave relationship table by use by a large number of users. Even if there is a facility that a specific user does not know and do not use, it is likely to be displayed due to the use of another user, resulting in the convenience of the user.

-Modification C:
In the said embodiment, although the smart phone was used as a terminal, various apparatuses, such as a vehicle-mounted navigation apparatus and a tablet terminal, can be used as a terminal. Further, part or all of the processing performed by the server 50 may be performed on the terminal side. Since the display area of a smartphone or the like is smaller than that of a tablet or the like, the display area may be automatically changed on the smartphone side when display is difficult. Alternatively, a note such as a facility name may not be displayed directly, but a pin or a bright spot may be displayed, and the facility name (note) may be displayed when the user taps it. Alternatively, it may be presented to the user by voice. When presenting by voice, as in the first embodiment, if route guidance is also provided, voice guidance such as “I will soon be a XX facility” or “I will soon stop at a XX facility” It may be done.

  The present invention is not limited to the above-described embodiments, examples, and modifications, and can be realized with various configurations without departing from the spirit thereof. For example, the technical features in the embodiments, examples, and modifications corresponding to the technical features in each embodiment described in the summary section of the invention are to solve some or all of the above-described problems, or In order to achieve part or all of the above effects, replacement or combination can be performed as appropriate. Further, if the technical feature is not described as essential in the present specification, it can be deleted as appropriate.
