Description

  The present invention relates to an information providing system, an information providing method, and a computer program that provide information related to a facility located on a map.

  2. Description of the Related Art In recent years, a navigation device is often mounted on a vehicle that provides vehicle travel guidance so that a driver can easily arrive at a desired destination. Here, the navigation device detects the current position of the vehicle by a GPS receiver or the like, acquires map data corresponding to the current position through a recording medium such as a DVD-ROM or HDD or a network, and displays it on a liquid crystal monitor. It is a device that can do. Further, in such a navigation device, information on facilities in the vicinity of the current position of the own vehicle or facilities in a specific area (for example, around the planned travel route) is also guided. In recent years, some mobile phones, smartphones, tablet terminals, personal computers, and the like have functions similar to those of the navigation device.

  Here, when guiding information related to the facility, it is common to search for facilities that meet the conditions desired by the user based on the conditions input by the user and to guide the facilities that meet the conditions. . On the other hand, Japanese Patent Application Laid-Open No. 2014-62912 and Japanese Patent Application Laid-Open No. 2006-119132 describe that a system is proposed from the system side even when a request from the user is not made.

JP 2014-62912 A (pages 17-18, FIG. 6) JP 2006-119132 A (page 8-10, FIG. 5)

  Here, in the techniques described in Patent Document 1 and Patent Document 2, it is described that a facility in an area along a planned travel route is proposed as a stopover for the user. In addition, the area to be proposed for the facility is a section of an address that includes at least a part of the planned travel route in Patent Document 1, and changes depending on the planned travel route, but is basically the same if the planned travel route is the same. It becomes a fixed area. On the other hand, Patent Document 2 describes that an area to be proposed for a facility is changed based on geographical conditions. For example, it is described that in the suburbs, the area is wider than that in urban areas.

  However, the tendency of the distance from the planned travel route to the facility where the user stops varies greatly from user to user. Therefore, there is a problem that an appropriate facility cannot be proposed only by using a configuration in which the area to be proposed for the facility is a fixed area or changed according to geographical conditions as in Patent Document 1 and Patent Document 2. As a result, a facility that is unnecessary for the user is repeatedly proposed, while a facility that is useful to the user may not be proposed.

  The present invention has been made to solve the above-described conventional problems, and it is possible to set a distance from a current position or a planned travel route to a facility to be proposed as a stopover destination according to the user's preference. Therefore, it is possible to provide an information providing system, an information providing method, and a computer program that can prevent a facility that is unnecessary for a user from being repeatedly proposed and that can appropriately propose a facility that is useful to the user. With the goal.

  In order to achieve the above object, an information providing system according to the present invention is extracted by a facility extraction unit that extracts a facility located within a suggested distance from a user's current position or the planned travel route of the user, and the facility extraction unit. A facility suggesting means for proposing the facility to the user as a stop point where the user stops; an acceptance result determining means for determining whether or not the facility proposed by the facility proposing means is accepted by the user as a stop point; Distance correction means for correcting the proposed distance based on the determination result of the acceptance result determination means.

  In addition, the information providing method according to the present invention is a method for proposing a facility that is a stop point for a user. Specifically, the facility extracting unit extracts a facility located within a suggested distance from the current position of the user or the planned travel route of the user, and the facility extracting unit extracts the facility extracted by the facility extracting unit. A step of proposing to the user as a stop point where the user stops, a step of determining whether or not an acceptance result determination unit has accepted the facility proposed by the facility suggestion unit as a stop point, and a distance correction And means for correcting the proposed distance based on the determination result of the acceptance result determination means.

  Further, the computer program according to the present invention is a program for proposing a facility that is a stop point for a user. Specifically, the user stops at a facility extraction means for extracting a facility located within a suggested distance from the current position of the user or the planned travel route of the user, and the facility extracted by the facility extraction means. Facility proposal means that proposes to the user as a stop point, acceptance result determination means that determines whether or not the facility proposed by the facility proposal means has been accepted by the user as a stop point, and determination results of the acceptance result determination means It is made to function as distance correction means which corrects the proposal distance based on this.

  According to the information providing system, the information providing method, and the computer program according to the present invention having the above-described configuration, the distance from the current position or the planned travel route to the facility to be proposed as a stopover destination is set according to the user's preference. Is possible. As a result, it is possible to prevent a facility that is unnecessary for the user from being repeatedly proposed, and to appropriately propose a facility that is beneficial to the user.

  Hereinafter, an information providing system according to the present invention will be described in detail with reference to the drawings based on an embodiment in which the navigation apparatus is embodied. First, a schematic configuration of the navigation device 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a navigation device 1 according to this embodiment.

  As shown in FIG. 1, the navigation device 1 according to the present embodiment includes a current position detection unit 11 that detects a current position of a vehicle on which the navigation device 1 is mounted, a data recording unit 12 that records various data, A navigation ECU 13 that performs various arithmetic processes based on the input information, an operation unit 14 that receives operations from the user, a liquid crystal display 15 that displays guidance information about a map and facilities around the vehicle to the user, Communication is performed between a speaker 16 that outputs voice guidance related to route guidance, a DVD drive 17 that reads a DVD as a storage medium, and an information center such as a probe center or a VICS (registered trademark: Vehicle Information and Communication System) center. And a communication module 18.

Below, each component which comprises the navigation apparatus 1 is demonstrated in order.
The current position detection unit 11 includes a GPS 21, a vehicle speed sensor 22, a steering sensor 23, a gyro sensor 24, and the like, and can detect the current vehicle position, direction, vehicle traveling speed, current time, and the like. . Here, in particular, the vehicle speed sensor 22 is a sensor for detecting a moving distance and a vehicle speed of the vehicle, generates a pulse according to the rotation of the driving wheel of the vehicle, and outputs a pulse signal to the navigation ECU 13. And navigation ECU13 calculates the rotational speed and moving distance of a driving wheel by counting the generated pulse. Note that the navigation device 1 does not have to include all the four types of sensors, and the navigation device 1 may include only one or more types of sensors.

  The data recording unit 12 reads an external storage device and a hard disk (not shown) as a recording medium, a map information DB 31, an acceptance determination result DB 32, a learning result DB, a predetermined program, etc. recorded on the hard disk and a hard disk And a recording head (not shown) which is a driver for writing predetermined data. The data recording unit 12 may be configured by a memory card, an optical disk such as a CD or a DVD, instead of the hard disk. Further, the map information DB 31 may be stored in an external server, and the navigation device 1 may be configured to acquire by communication.

  Here, the map information DB 31 includes, for example, link data 34 relating to roads (links), node data 35 relating to node points, facility data 36 relating to facilities, map display data for displaying maps, intersection data relating to each intersection, and routes. It is a storage means in which search data for searching, search data for searching for points, and the like are stored.

  The link data 34 includes, for each link constituting the road, the width of the road to which the link belongs, the gradient, the cant, the bank, the road surface condition, the number of road lanes, the number of lanes that decrease, The data representing the narrowing point, railroad crossing, etc., the corner, the radius of curvature, the intersection, the T-junction, the corner entrance and the exit, etc. The data representing the downhill road, the uphill road, etc. Regarding types, in addition to general roads such as national roads, prefectural roads and narrow streets, data representing toll roads such as highway automobile national roads, city expressways, automobile exclusive roads, general toll roads, and toll bridges are recorded.

  Further, as the node data 35, actual road branch points (including intersections, T-junctions, etc.) and the coordinates (positions) of node points set for each road according to the radius of curvature, etc. Node attribute indicating whether a node is a node corresponding to an intersection, etc., a connection link number list that is a list of link numbers of links connected to the node, and an adjacency that is a list of node numbers of nodes adjacent to the node via the link Data relating to the node number list, the height (altitude) of each node point, and the like are recorded.

Further, as the facility data 36, information related to a facility that is a departure point, a destination, a guidance target, and the like in the navigation device 1 is stored. For example, accommodation facilities such as hotels and inns, refueling facilities such as gas stations, commercial facilities such as shopping malls, supermarkets, shopping centers and convenience stores, entertainment facilities such as theme parks and game centers, restaurants, bars and pubs Information on facilities such as facilities, parking facilities such as public parking lots, transportation facilities, religious facilities such as temples and churches, public facilities such as museums and museums, and the like.
The facility data 36 includes, for each facility, a facility number that is an identifier of the facility, a facility name that indicates the name of the facility, and a facility genre that indicates the genre of the facility (such as “parking lot”, “post office”, and “restaurant”). It is composed of position coordinates indicating the position of the facility.

Here, FIG. 2 is a diagram showing an example of the facility data 36.
For example, in the example of the facility data 36 shown in FIG. 2, it is shown that “convenience store XX chain A branch (genre: convenience store)” corresponding to the facility number: “10001” exists at the point of coordinates (x1, y1). Show. Further, it is indicated that “XX bow (genre: ramen)” corresponding to the facility number: “10002” exists at the point of coordinates (x2, y2). Similarly, information on other facilities is also stored.

  On the other hand, the acceptance determination result DB 32 accumulates the results of whether or not the user has accepted the proposed facility as a stop point as a result of the facility proposed as a stop point (via point) where the user stops in the navigation device 1 in the past. It is the memory | storage means memorize | stored.

  Here, in the present embodiment, when the user travels along the planned travel route (guide route set in the navigation device 1), a facility located within a predetermined suggested distance from the planned travel route As a suggestion to the user. For example, FIG. 3 is a diagram showing a travel guidance screen 50 displayed on the liquid crystal display 15 while traveling with the guidance route set in the navigation device 1. The travel guidance screen 50 displays a map image 51 around the current position of the vehicle, a guidance route 52, a destination 53, and a vehicle position mark 54 indicating the current position of the matched vehicle on the map. In addition, a facility mark 55 indicating the location of the facility proposed to the user as a stop-off point at an arbitrary timing, and an information window 56 that displays recommended information, a facility name, and the like for the facility are also displayed. The stop point may be proposed every time a predetermined time has elapsed since the vehicle started traveling, or whenever the traveling distance becomes a predetermined distance, or may be performed at a predetermined time. In addition to the map information around the current vehicle and the currently set guidance route, the user can grasp the recommended facilities around the guidance route by referring to the travel guidance screen 50. Become.

  In addition, the “suggested distance” that defines the scope of the facility when making the above proposal is set for each genre of the facility to be proposed and for each environment (for example, day of the week, time zone, weather, weekday holiday classification) Is corrected based on the degree of acceptance of the proposal by the user. Therefore, in the acceptance determination result DB 32, in order to correct the proposed distance to an appropriate distance, whether or not the user has proposed the proposed facility as a stop-by point according to the genre of the facility and for each environment, that is, The result of whether or not the user actually stopped at the proposed facility is stored. In the following description, a case where the proposed distance is set for each day of the week will be described as an environment.

  For example, FIG. 4 shows an example of the history stored in the acceptance determination result DB 32. As shown in FIG. 4, the total number of proposals made so far and the number of times the user accepted the proposal are stored for each genre of the proposed facility and for each day of the week when the proposal was made. ing. For example, for facilities corresponding to the genre “Ramen”, the user has been proposed as a drop-in point 30 times so far on Monday, and the facility proposed by the user 19 times has been accepted as a drop-in point It is shown that. In addition, on Tuesday, the user has been proposed 42 stop points so far, and the user has accepted the proposed facility as a stop point 28 times. Similarly, other days of the week and genres are also stored. Then, the navigation ECU 13 corrects the proposed distance to an appropriate value according to the user's preference for each genre of facility and for each day of the week based on the history stored in the acceptance determination result DB 32 as described later.

  In addition, the learning result DB 33 is a history stored in the above-described acceptance determination result DB 32, that is, whether or not the user has accepted the proposed facility as a stop point as a result of the facility being proposed as a stop point in the navigation device 1 in the past. The storage means stores a list of corrected suggested distances (that is, learned learned distances) based on the history of the results.

  For example, FIG. 5 shows an example of the suggested distance stored in the learning result DB 33. As shown in FIG. 5, the suggested distance based on the learning result at the present time is stored for each genre of facility and for each day of the week. For example, for a facility corresponding to the genre “Ramen”, “suggested distance” is set to 800 m on Monday, “suggested distance” is set to 800 m on Tuesday, “suggested distance” is set to 600 m on Wednesday, and Thursday is “Proposed distance” is set to 600 m, “Proposed distance” is set to 500 m on Friday, “Suggested distance” is set to 1200 m on Saturday, and “Suggested distance” is set to 1200 m on Sunday ing. In addition, about the blank part, the history corresponding to the acceptance determination result DB 32 is not sufficiently stored at present (for example, the number of proposals is less than 20), and the optimum “proposed distance” based on the learning result cannot be calculated. Indicates.

  The navigation ECU (Electronic Control Unit) 13 is an electronic control unit that controls the entire navigation device 1. The CPU 41 as an arithmetic device and a control device, and a working memory when the CPU 41 performs various arithmetic processes. Read out from the ROM 43 and the ROM 43 in which the RAM 42 that stores the route data when the route is searched, the control program, the facility proposal processing program (FIG. 6) described later, and the like are recorded. An internal storage device such as a flash memory 44 for storing the program is provided. The navigation ECU 13 constitutes various means as processing algorithms. For example, the facility extraction unit extracts a facility located within the suggested distance from the current position of the user or the planned travel route of the user. The facility proposal means suggests the extracted facility to the user as a stop-off point where the user stops. The acceptance result determination means determines whether or not the proposed facility has been accepted by the user as a stopover point. The distance correction means corrects the suggested distance based on the determination result of the acceptance result determination means.

  The operation unit 14 is operated when inputting a departure point as a travel start point and a destination as a travel end point, and includes a plurality of operation switches (not shown) such as various keys and buttons. Then, the navigation ECU 13 performs control to execute various corresponding operations based on switch signals output by pressing the switches. The operation unit 14 can also be configured by a touch panel provided on the front surface of the liquid crystal display 15. Moreover, it can also be comprised with a microphone and a speech recognition apparatus.

  The liquid crystal display 15 includes a map image including a road, traffic information, operation guidance, operation menu, key guidance, guidance route from the departure point to the destination, guidance information along the guidance route, news, weather forecast, Time, mail, TV program, etc. are displayed. Moreover, it is used also when displaying the information of the facility proposed as a stopover point. In place of the liquid crystal display 15, HUD or HMD may be used.

  Further, the speaker 16 outputs voice guidance for guiding traveling along the planned traveling route and traffic information guidance based on an instruction from the navigation ECU 13.

  The DVD drive 17 is a drive that can read data recorded on a recording medium such as a DVD or a CD. Based on the read data, music and video are reproduced, the map information DB 31 is updated, and the like.

  The communication module 18 is a communication device for receiving traffic information composed of information such as traffic jam information, regulation information, and traffic accident information transmitted from a traffic information center, for example, a VICS center or a probe center. For example, a mobile phone or DCM is applicable.

  Next, a facility proposal processing program executed by the CPU 41 in the navigation device 1 having the above configuration will be described with reference to FIG. FIG. 6 is a flowchart of the facility proposal processing program according to this embodiment. Here, the facility proposal processing program is executed after the guidance route is set in the navigation device 1 and proposes facilities of various genres to the user as a stop-off point, and future proposals based on acceptance results of the user's suggestions. It is a program that corrects the scope of facilities to be operated. Note that the program shown in the flowchart of FIG. 6 below is stored in the RAM 42 or ROM 43 provided in the navigation apparatus 1 and is executed by the CPU 41.

  First, in step (hereinafter abbreviated as S) 1 in the facility guidance processing program, the CPU 41 obtains a guidance route (a user's scheduled travel route) currently set in the navigation device 1. The guide route is a recommended route from the starting point to the destination set by the navigation device 1, and is searched using, for example, a known Dijkstra method. The guide route may be configured to be searched by the navigation device 1 or may be configured to be searched by an external server. Further, the departure point may be the current position of the user or an arbitrary point selected by the user (for example, home).

  Next, in S <b> 2, the CPU 41 acquires a list of learned “suggested distances” corresponding to the current day of the week from the learning result DB 33. Here, as described above, the proposed distance based on the current learning result is stored in the learning result DB for each genre of facility and for each day of the week (FIG. 5). Therefore, in S <b> 2, the CPU 41 obtains a list of “suggested distances” set for each genre corresponding to the current day of the week from the learning result DB 33. It should be noted that genres having no learned “proposed distance” are excluded from acquisition targets.

  In addition, the process after S3 is performed for every genre of all facilities. And after the process after S3 is complete | finished for the genre of all the facilities, the said facility proposal process program is complete | finished.

  First, in S3, the CPU 41 determines whether or not there is a learned “suggested distance” corresponding to the current day of the week for the genre to be processed. Specifically, it is determined that there is a learned “suggested distance” for the genre for which “suggested distance” is acquired in S2.

  If it is determined that there is a learned “suggested distance” corresponding to the current day of the week for the processing target genre (S3: YES), the process proceeds to S4. On the other hand, if it is determined that there is no learned “proposed distance” corresponding to the current day of the week for the processing target genre (S3: NO), the process proceeds to S5.

  In S <b> 4, the CPU 41 reads the learned “suggested distance” corresponding to the current day of the week for the processing target genre from the learning result DB 33. For example, when the learning result DB 33 shown in FIG. 5 is stored, the current day of the week is Saturday, and the genre to be processed is ramen, 1200 m is read as the learned “suggested distance”.

  On the other hand, in S5, since there is no learned “proposed distance”, the CPU 41 acquires a predetermined reference distance (for example, 500 m) as the “proposed distance”. The reference distance value may be a different distance for each day of the week or each genre.

  After that, in S6, the CPU 41 determines whether there is a facility of a genre to be processed that is recommended to the user as a stopover destination for the area within the suggested distance acquired in S4 or S5 from the guidance route. Specifically, first, a facility of a genre to be processed (for example, ramen) located in the corresponding area is extracted from the facility data 36. Thereafter, it is determined whether there is a facility recommended to the user as a stop-off destination in the extracted facilities in consideration of the evaluation of the facility, the user's preference, and the like. For example, a facility evaluation is acquired from an external server by communication, and a facility whose evaluation is equal to or greater than a threshold is recommended as a facility to be visited by the user.

  If it is determined that there is a facility of a genre to be processed recommended as a stopover in an area within the suggested distance from the guidance route (S6: YES), the process proceeds to S7. On the other hand, if it is determined that there is no facility of the genre to be processed recommended to the user as a stopover in the area within the suggested distance from the guide route (S6: NO), the facility is not proposed to the user. Return to S3. Thereafter, the genre to be processed is changed, and the processes after S3 are executed.

  In S <b> 7, the CPU 41 extracts, from the facility data 36, a facility of a genre to be processed that is recommended to the user as a stopover in an area within the suggested distance from the guide route, and proposes the extracted facility to the user as a stoppage point of the user. For example, as shown in FIG. 3, in the travel guidance screen 50 displayed on the liquid crystal display 15, the facility proposal is a facility mark 55 indicating the location of the facility proposed to the user, recommended information for the facility, a facility name, etc. Is performed using an information window 56 for displaying.

  Next, in S8, the CPU 41 updates the acceptance determination result DB 32 (FIG. 4). Specifically, +1 is added to the number of proposals corresponding to the current day of the week (day of the proposal) and the genre to be processed (genre for which the proposal was made).

  Next, in S9, the CPU 41 determines whether or not the facility proposed in S7 has been accepted by the user as a stopover point. Specifically, the current position of the vehicle is periodically acquired, and when the vehicle arrives at the proposed facility, it is determined that the facility proposed in S7 has been accepted by the user as a stopover point. On the other hand, when a certain time has passed without the vehicle reaching the proposed facility, or when the destination is reached, it is determined that the facility proposed in S7 has not been accepted by the user as a stopover point.

  If it is determined that the facility proposed in S7 has been accepted by the user as a stopover point (S9: YES), the process proceeds to S10. In S10, the CPU 41 updates the acceptance determination result DB 32 (FIG. 4). Specifically, +1 is added to the number of times the proposal corresponding to the current day of the week (day of the proposal) and the genre to be processed (genre for which the proposal was made). Thereafter, the process proceeds to S11.

  On the other hand, if it is determined that the facility proposed in S7 has not been accepted by the user as a stopover point (S9: NO), the process proceeds to S11 without updating the acceptance determination result DB32.

  In S11, the CPU 41 refers to the acceptance determination result DB 32 corresponding to the current day of the week and the genre to be processed, and determines whether the total number of proposals is 20 or more.

  And when it determines with the sum total of the frequency | count of proposal being 20 times or more (S11: YES), it transfers to S12. On the other hand, when it is determined that the total number of proposals is less than 20 (S11: NO), it is determined that the number of histories is insufficient and an appropriate proposal distance cannot be specified based on the learning result. And it returns to S3, without memorizing the suggestion distance based on a learning result in learning result DB33.

  In S12, the CPU 41 refers to the acceptance determination result DB 32 corresponding to the current day of the week and the genre to be processed, and determines whether the ratio of the number of acceptances to the total number of proposals is 80% or more.

  And when it determines with the ratio of the frequency | count of acceptance with respect to the sum total of the proposal frequency being 80% or more (S12: YES), it transfers to S13. On the other hand, when it is determined that the ratio of the number of acceptances to the total number of proposals is less than 80% (S12: NO), the process proceeds to S14.

  In S13, the CPU 41 estimates that the current proposed distance is shorter than the appropriate distance according to the user's preference, and corrects the proposed distance. Specifically, the learned “suggested distance” corresponding to the current day of the week and the genre to be processed is read from the learning result DB 33, and the read “suggested distance” (provided that the reference distance is set as the proposed distance in S5). The reference distance) is corrected to 1.2 times. Then, the corrected “proposed distance” is stored again in the learning result DB 33 as the learned “proposed distance”. As a result, as shown in FIG. 7, in the facility proposal process (S7) to be executed after the next time, the facility range 61 to be proposed becomes wider along the guide route 52. That is, the facility farther away from the guidance route is also proposed to the user as a stopover point.

  Next, in S14, the CPU 41 refers to the acceptance determination result DB 32 corresponding to the current day of the week and the genre to be processed, and determines whether the ratio of the number of acceptances to the total number of proposals is less than 60%.

  And when it determines with the ratio of the frequency | count of acceptance with respect to the total of the frequency | count of proposal being less than 60% (S14: YES), it transfers to S15. On the other hand, when it is determined that the ratio of the number of acceptances to the total number of proposals is 60% or more (S14: NO), the process proceeds to S16.

  In S15, the CPU 41 estimates that the current suggested distance is longer than the appropriate distance according to the user's preference, and corrects the proposed distance. Specifically, the learned “suggested distance” corresponding to the current day of the week and the genre to be processed is read from the learning result DB 33, and the read “suggested distance” (provided that the reference distance is set as the proposed distance in S5). The reference distance) is corrected to 0.8 times. The corrected “suggested distance” is stored again in the learned learning result DB 33. As a result, as shown in FIG. 8, in the facility proposal process (S7) to be executed after the next time, the facility range 61 to be proposed becomes narrower along the guide route 52. In other words, only facilities that are close to the guide route are suggested to the user as a stopover point.

  As a result, for example, it is assumed that a certain user is interested in a cafe, and if it is a cafe, he / she also stops at a facility that is far from the guidance route, but other restaurants tend to stop only at facilities near the guidance route. In that case, it should be proposed as a stop point even for facilities that are far from the guide route for cafes, while only restaurants near the guide route should be proposed as stop points for other restaurants. Is desirable. Therefore, in S13, the “suggested distance” is corrected so that a facility of a genre that the user often stops by is suggested as a stopover point even in a facility that is far from the guidance route, while in S15, a facility of a genre that the user does not stop much. With regard to, it is possible to modify the “suggested distance” so that only facilities in the vicinity of the guidance route are proposed as stops.

  On the other hand, in S16, the CPU 41 estimates that the current suggested distance is an appropriate distance according to the user's preference, and does not correct the learned “suggested distance” corresponding to the current day of the week and the genre to be processed. To keep the current distance.

  As described in detail above, in the navigation device 1 according to the present embodiment, the information providing method by the navigation device 1, and the computer program executed by the navigation device 1, the facility located within the proposed distance from the user's planned travel route is selected by the user. On the other hand, it is determined whether the proposed facility is accepted by the user as a stop point (S9), and the proposed distance is corrected based on the determination result (S13, S15). With this configuration, it is possible to set the distance from the planned travel route to the facility to be proposed as a stopover destination according to the user's preference. As a result, it is possible to prevent a facility that is unnecessary for the user from being repeatedly proposed, and to appropriately propose a facility that is beneficial to the user.

Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.
For example, in the present embodiment, the range of the facility proposed to the user as the stop point of the user is a range within the suggested distance from the planned travel distance of the user, but may be a range within the suggested distance from the current position of the user. In that case, the present invention can be applied even in a state where no guidance route is set in the navigation device 1.

  In the present embodiment, the optimum proposed distance is set by increasing or decreasing the proposed distance based on the ratio of the number of times the user has accepted the proposal with respect to the number of proposals (S13, S15, S16). However, the distance from the guidance route to the facility that made the proposal is also stored in the acceptance determination result DB 32, and the number of proposals made for each distance section (for example, 0 m to 300 m, 300 m to 600 m, 600 m to 900 m, etc.) Alternatively, the ratio of the number of times the proposal is accepted by the user may be calculated, and the proposed distance may be set based on the distance section with the highest ratio.

  In the present embodiment, the proposed distance is set for each day of the week and for each genre. However, the proposed distance may be set for each time zone (for example, morning, noon, night), for each weather, and for each weekday and holiday category. good.

  In addition to the navigation device, the present invention can be applied to a device having a function of performing user travel guidance. For example, the present invention can be applied to a mobile phone, a smartphone, a tablet terminal, a personal computer (hereinafter referred to as a mobile terminal). Further, the present invention can be applied to a system including a server and a mobile terminal. In that case, each step of the above-described facility proposal processing program (FIG. 6) may be implemented by either a server or a mobile terminal.

  Moreover, although the embodiment which actualized the information providing system according to the present invention has been described above, the information providing system can also have the following configuration, and in this case, the following effects can be obtained.

For example, the first configuration is as follows.
A facility extracting means for extracting a facility located within a suggested distance from the current position of the user or the planned travel route of the user, and the facility extracted by the facility extracting means is proposed to the user as a stop point where the user stops Correcting the proposed distance based on the determination result of the facility proposal means, the acceptance result determination means for determining whether or not the facility proposed by the facility proposal means has been accepted by the user as a stopover point, and the acceptance result determination means And a distance correcting means.
According to the information providing system having the above-described configuration, it is possible to set the distance from the current position or the planned travel route to the facility to be proposed as a stopover destination according to the user's preference. As a result, it is possible to prevent a facility that is unnecessary for the user from being repeatedly proposed, and to appropriately propose a facility that is beneficial to the user.

The second configuration is as follows.
The proposed distance is set for each genre of the facility to be extracted, and the distance correcting unit corrects the proposed distance corresponding to the genre of the facility to be determined by the acceptance result determining unit. To do.
According to the information providing system having the above-described configuration, it is possible to set the distance from the current position or the planned travel route to the facility to be proposed as a stopover destination according to the user's preference for each genre of facility. For example, for facilities of a genre that the user is interested in, facilities that are far from the current position or guide route are also proposed, and for facilities of other genres, only facilities near the current location or guide route are proposed. By doing so, it becomes possible to propose a facility more in line with the user's preferences.

The third configuration is as follows.
The proposed distance is set for each environment when extraction is performed, and the distance correction unit corrects the proposed distance corresponding to the environment when the facility that is the determination target of the acceptance result determination unit is extracted. It is characterized by that.
According to the information providing system having the above-described configuration, it is possible to set the distance from the current position or the planned travel route to the facility to be proposed as a stopover destination according to the user's preference for each environment. For example, for Saturdays, Sundays, and holidays where the user has enough time, the facility that is far from the current position and guidance route is also proposed, and on weekdays, only the facilities near the current location and guidance route are proposed. It becomes possible to propose a facility more in line with the user's preferences.

The fourth configuration is as follows.
Accumulation storage means for accumulating and storing the determination results of the acceptance result determination means, and the distance correction means is accepted by the user as a stop-off point among the determination results accumulated and stored by the accumulation storage means. The proposed distance is corrected based on the ratio of the determination results.
According to the information providing system having the above-described configuration, the proposed distance is corrected based on the proportion of the users who have accepted the proposal up to now, so that a more appropriate proposed distance can be set based on the learning result.
