A2. Generate route data:
FIG. 3 is a chart showing exchange of information among the mobile phone 200, the route search server 100, and the area information server 180 when performing route search.

  In step S110, when receiving a route search instruction from the user, the main control unit 210 of the mobile phone 200, the information of the departure point and the destination, the date of the waypoint and the date the user moves along the route, the use of the expressway Information on search conditions such as information specifying the presence / absence of is transmitted to the route search server 100.

  In step S <b> 210, the control unit 104 of the route search server 100 searches for a route based on information on the departure point and destination, information on search conditions, and the like while referring to route network data in the storage unit 106.

  In step S220, the route search server 100 transmits the information (node information and arc information) of the position of each point on the determined route to the region information server 180, and inquires about information on a specific region near the route.

  In step S <b> 310, the area information server 180 refers to the area database 186 and determines a specific area near the route based on the information on the position of the route received from the route search server 100. Information on these specific areas is transmitted to the route search server 100.

  More specifically, a specific area that at least partially overlaps an area having a width of a predetermined distance around the route is selected in principle in step S310. For example, in the example of FIG. 2, the route determined in step S210 is R0. In step S310, in addition to the specific areas A1 and A3 through which the route R0 passes, there is also a specific area A2 that partially overlaps the area R0e having a width of a predetermined distance (for example, 500 m) on both sides with respect to the path R0. Selected. A region having a width of a predetermined distance on both sides centering on the route is a range within a predetermined distance from an arbitrary point on the route.

  When the date received from the route search server 100 as the date when moving the route is outside the time when the characteristics of a specific area are exhibited, the area information server 180 determines that the specific area is near the path. Even if it exists, the specific area | region is not selected in step S310.

  When the route search server 100 receives the data of the specific region from the region information server 180, in step S230, the route search server 100 generates route data based on the information on the route determined in step S210 and the information on the specific region near the route. . The generated route data is stored in the storage unit 106 of the route search server 100 together with information such as a departure place, a destination, and a search condition.

  The route data includes node information and arc information of points included in the route, and attribute information of intersections and stations. The arc information further includes information of a point sequence of latitude and longitude. The route data includes information for the above-described travel guidance and information on a specific area near the route. Note that node information and arc information may be collectively referred to as “route information”. The specific area information will be described later in detail.

  The route data generated by the route search server 100 in step S230 is transmitted from the route search server 100 to the mobile phone 200 in step S240. The mobile phone 200 receives the route data. A functional unit of the main control unit 210 that transmits information such as a departure point, a destination, and search conditions to the route search server 100 and receives route data from the route search server 100 is a route preparation unit 231 (see FIG. 1). .

  Thereafter, when an instruction to start the route guide is input via the command input unit 206, the main control unit 210 of the mobile phone 200 executes the route guide in step S120. The route guide is performed based on route data received from the route search server 100. Further, the main control unit 210 of the mobile phone 200 separately displays a map around the current position along with the route on the display panel 202 based on the map image data acquired from the map server 150.

  In addition, the function part of the main control part 210 which acquires map image data from the map server 150 is shown as the map information preparation unit 233 in FIG. Moreover, the function part of the main control part 210 which performs route guidance based on route data is the route guidance unit 232 (refer FIG. 1).

  In this specification, the route guide may be referred to as “route guidance”. On the other hand, for example, the process of instructing how to turn each intersection or instructing the traveling direction at the time of branching is called “movement guidance”.

  FIG. 4 is a flowchart showing details of processing in the route search server 100. In step S210, the control unit 104 of the route search server 100 searches for a route from the departure point to the destination. In FIG. 4, steps denoted by the same reference numerals as in FIG. 3 represent the same steps as in FIG.

  FIG. 5 is an example of an image displayed on the display panel 202 of the mobile phone 200 in the route guide in order to guide the traveling direction at the road branch. When searching for a route in Step S210, the control unit 104 of the route search server 100 generates data used for guidance for moving along the route (hereinafter referred to as “movement guidance”). As data used for guidance for moving along a route, for example, image data for guiding how to bend at an intersection, or for guiding a traveling direction at a road branch as shown in FIG. There is data of the image GD1.

  In step S210, the control unit 104 of the route search server 100 also determines at which point on the route such guidance is to be performed. A point where guidance for moving along a route is performed is referred to as a “guide point”. The guide point is determined based on the node information and arc information of the route. For example, the guide point is a point on the route, and a point that is a predetermined distance away from an intersection or branch.

  Data representing the position of a guide point, such as image data and voice data used for travel guidance, is included in the route data when generating route data. A functional unit of the control unit 104 that performs the process of step S210 is shown as a route determination unit 111.

  Steps S224 and S226 in FIG. 4 described below describe in detail the processing content of step S220 in FIG.

  In step S224 of FIG. 4, the control unit 104 of the route search server 100 inquires of the area information server 180 about a specific area (see FIG. 3). Then, the control unit 104 of the route search server 100 receives specific area information from the area information server 180.

  In step S226, the control unit 104 of the route search server 100 selects a specific area from the specific area received from the area information server 180 according to a predetermined condition. For example, a specific area in the vicinity of a section using the expressway is excluded in principle from the route, and other specific areas are selected. If the range from an arbitrary point in the section using the expressway to a predetermined distance (for example, 500 m) and at least a part of a specific area overlap, the specific area is in the vicinity of the section using the expressway. It shall be. In step S226, the predetermined distance serving as a reference whether or not the specific area is in the vicinity of the expressway is the predetermined distance serving as a reference whether or not the specific area is in the vicinity of the route in step S310 of FIG. Same as or shorter than.

  In step S226, as described above, the specific area in the vicinity of the section using the highway is excluded in principle. However, the specific area that overlaps the interchange on the expressway on the route and the range in the vicinity of the interchange exiting from the expressway (for example, within a circle having a radius of 500 m centering on the interchange) is selected in step S226. In FIG. 2, the range in the vicinity of the interchange i1 on the route on the highway is indicated by Ri1. A range in the vicinity of the interchange i2 descending from the highway on the route is indicated by Ri2.

  In FIG. 2, the route R0 is the route searched in step S210 of FIGS. In the route R0, the section from the interchange i1 to the interchange i2 is a section using the expressway. For this reason, the specific area A3 is not selected in step S226. On the other hand, the specific area A2 is a specific area in the vicinity of the section using the highway, but is a specific area overlapping the range Ri2 in the vicinity of the interchange i2 that gets off the highway on the route. For this reason, the specific area A2 is selected in step S226.

  By adopting such a mode, it is possible not to introduce a specific area that cannot be detoured because of being on a highway or a specific area that is unlikely to be detoured during route guidance. it can. For this reason, the user is not bothered by the introduction of unnecessary specific areas during the route guide.

  Steps S224 and S226 of FIG. 4 described below correspond to the process of step S220 of FIG. A functional unit of the control unit 184 of the region information server 180 that determines a specific region near the route is shown as a region determination unit 188 in FIG. In addition, the function unit of the control unit 104 of the route search server 100 that performs the processing of steps S224 and S226 to determine a specific region that satisfies a predetermined condition from the specific regions near the route is shown in FIG. As shown. These region determination unit 112 and region determination unit 188 determine a specific region in which information is to be incorporated into the route data.

  FIG. 6 is a diagram showing an image ID1 displayed on the display panel 202 of the mobile phone 200 in order to introduce a specific area to the user during the route guide. The specific area selected in step S226 is introduced to the user during the route guide using, for example, a display as shown in FIG. The image ID1 for introducing the specific area to the user includes a display DM1 related to the enjoyment of the specific area and a button B01 for presenting individual places where the user can enjoy the enjoyment of the specific area. Hereinafter, introduction of a specific area is referred to as “area introduction”.

  Steps S234 and S236 in FIG. 4 to be described below describe the processing contents of step S230 in FIG. 3 in detail.

In step S234 in FIG. 4, for each specific area selected in step S226, a point where the area is introduced to the user (hereinafter referred to as “introduction point”) is determined on the route.
The introduction point is a point on the route and included in a predetermined range in the selected specific area or in the vicinity of the specific area. Then, the introduction point is determined avoiding a predetermined range including a guide point for performing movement guidance as shown in FIG.

  FIG. 7 is a diagram illustrating a relationship between a point pg1 where movement guidance for moving along a route (see FIG. 5) and points p11 and p11m where a specific region is introduced (see FIG. 6). . 7, elements indicated by the same reference numerals as those in FIG. 2 indicate the same elements as those in FIG.

  In step S234, first, a point where the route enters the specific area is specified. 2 and 7, the route R0 is a route from the lower left to the upper right. Therefore, the point where the route R0 enters the specific area A1 is the point p10.

  Then, a point just before a predetermined distance (for example, 500 m) along the route from the point where the route enters the specific area is determined as an introduction point candidate. This point is included inside the range of a predetermined distance with a linear distance from the outer edge of the specific region. In FIG. 7, the candidate point is p11.

  Then, it is determined whether or not the candidate point is within a predetermined range (for example, a range of 300 m before and after the guide point, hereinafter referred to as “prohibited range”) including the guide point where the travel guidance (see FIG. 5) is performed. The When the candidate point is not within the prohibited range, the candidate point is determined as the introduction point.

  When the point where the route enters the extended area is within the prohibited range, the same examination is performed with a point downstream from that point as a candidate value point by a predetermined distance (for example, 800 m). By repeating such processing, candidate points that are not within the prohibited range are determined as introduction points. However, when the candidate point is outside the specific area, the introduction point is not determined. As a result, the specific area is not introduced in the route guide.

  In the example of FIG. 7, the route R0 is a route that goes straight through the intersection pc1. For this reason, when the intersection pc1 between the searched route R0 and the road R1 is a normal intersection, the route guide does not provide movement guidance regarding the intersection pc1. Therefore, the point p11 is not within the prohibited range, and the point p11 is determined as the introduction point of the specific area A1.

  On the other hand, when the intersection pc1 between the route R0 and the road R1 is a three-dimensional intersection, for example, and there is a branch for the three-dimensional intersection before the intersection pc1, movement guidance is performed (see FIG. 5). In step S210 of FIG. 4, it is assumed that a point pg1 that is a predetermined distance (for example, 500 m) from the intersection pc1 is determined as the guide point.

  In the example of FIG. 7, the candidate point p11 is located within the prohibited range Rg1 including the point pg1. For this reason, whether or not a point p11m that is 800 m downstream from the candidate point p11 is newly set as a candidate value point and is included in the prohibited range is examined. Since the point p11m is not located within the prohibited range, the point p11m is set as the introduction point. In addition, in FIG. 7, the guidance point which performs the movement guidance regarding the intersection pc2 is shown by pg2. A prohibited range centered on the guide point pg2 is indicated by Rg2.

  By setting it as such an aspect, in the route guide, the situation where area introduction interferes with movement guidance can be prevented. Therefore, the user can safely proceed toward the destination on the route according to the route guide (see step S120 in FIG. 3), and can receive an introduction of the region in the vicinity of the route.

  In step S236 of FIG. 4, data used for movement guidance (see FIG. 5), data used for region introduction (see FIG. 6), and data representing the position of the guidance point (see point pg1 in FIG. 7). Alternatively, route data including data representing the position of the introduction point (see point p11m in FIG. 7) is generated. Note that the data used for travel guidance and the data used for region introduction include image data (including moving image data), text data (see FIGS. 5 and 6), audio data, and the like, respectively. it can.

  Steps S234 and S236 in FIG. 4 described above correspond to step S230 in FIG. A functional unit of the control unit 104 of the route search server 100 that performs the processing of steps S234 and S236 to generate route data is shown as a route data generation unit 113 in FIG.

  In step S240, the route search server 100 transmits route data to the mobile phone 200.

  Thereafter, in the route guide performed in step S120 of FIG. 3, when the current position reaches the guidance point, movement guidance is performed (see FIG. 5). In addition, when the current position reaches the introduction point, display DM1 (see FIG. 6) regarding the enjoyment in the specific area is performed, and at the same time, voice guidance is performed to perform the area introduction.

  According to such an aspect, the user can consider a detour by receiving an introduction of a specific area in the vicinity of the route during the route guide.

  In addition, after display DM1 (refer FIG. 6) regarding the enjoyment of a specific area | region is performed, when the instruction | indication from a user is not input into the mobile phone 200 for a predetermined time, the display DM1 regarding the enjoyment of a specific area is displayed. Disappears. For this reason, a useful specific area can be introduced to the user, and movement guidance is not hindered during normal movement on the route.

  FIG. 8 is an image showing the result of the point search. When taking a detour after receiving an introduction of a specific area in the route guide, the user clicks a button B01 (see FIG. 6) in the area introduction display ID1. Then, a list of places where the user can enjoy the enjoyment of the specific area is presented. Here, since the specific area is “an area where there are many delicious ramen shops”, a list of ramen shops is presented as a list of places where the user can enjoy the enjoyment of the specific area, as shown in FIG. If the specific area is a specific area with beautiful autumn leaves, a list of locations with beautiful maple trees and parking lot locations is presented.

  Note that the mobile phone 200 may display the list as described above based on the route data stored in the RAM of the main control unit 210, or the data obtained by requesting the route search server 100. Such a list may be displayed based on this. A functional unit of the main control unit 210 that displays a screen that prompts the user to input information is shown as a request unit 234 in FIG. A function unit of the main control unit 210 that performs a function of receiving information input from the user is shown as an input unit 235 in FIG.

  The user then selects individual elements from the list to obtain detailed information. Specifically, by operating the command input unit 206 of the mobile phone 200 and selecting and clicking one of the lists in FIG. 8, introductions of individual ramen shops are displayed. Then, by clicking a “re-search” button (not shown) displayed on the screen, the mobile phone 200 is instructed to search for a route to the destination via the point (ramen store). Entered.

  Thereafter, an instruction to search for a route to the destination via the point designated by the user (ramen store) is transmitted from the mobile phone 200 to the route search server 100. Subsequent route data generation processing is as described with reference to FIGS.

  By setting it as such a mode, the user can change a path | route easily and can take a detour in the path | route which goes to a destination. Further, since the detour is first guided as a region (see FIGS. 2 and 6), there is a low possibility of passing near the detour candidate, and there is a possibility that the detour can be departed without turning back the region that has passed. Is expensive.

B. Variation:
The present invention is not limited to the above-described examples and embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

B1. Modification 1:
Map image data as image data stored in the map database 156 of the map server 150 may be stored as raster data or may be stored as vector data. The map image data transmitted to the mobile phone 200 as a terminal device carried by the user may be raster data or vector data. Further, one of the map image data in the map database 156 and the map image data transmitted to the terminal device can be vector data and the other can be raster data.

B2. Modification 2:
In the above embodiment, the entire geographical area of Japan is divided into rectangular sections of a predetermined size, and the specific area is defined by the combination of the sections. However, the specific region may be a region in which a part of the region is specified in an arbitrary shape.

B3. Modification 3:
In the above embodiment, the introduction point for introducing the region to the user is determined avoiding a predetermined range including the guide point for performing the guidance for moving along the route (see FIG. 7). However, the introduction point for introducing the region to the user can be determined in other manners.

(1) For example, first, the control unit 104 of the route search server 100 is a section between adjacent guide points (in the example of FIG. 7, guide points pg1, pg2) in the route, and at least a part thereof. Is searched for a section included in the specific area. Furthermore, the control part 104 determines the area where the distance between adjacent guidance points is more than predetermined value (for example, 800 m) among such areas. The control unit 104 sets a predetermined point near the point where the route enters the specific area (point p10 in the example of FIG. 7) within the section as the introduction point.

  Specifically, the control unit 104 sets a point on the route that is a predetermined distance from the point where the route enters the specific area as the first candidate point. That is, the first candidate value point exists within a predetermined range in the vicinity of the specific area. If the candidate value point is not in the prohibited range including the guidance point, the candidate value point is set as the introduction point. If the candidate value point is within the prohibited range, a point downstream from the candidate value point on the route is set as the introduction point. The contents of this process can be the same as the process of determining the introduction point in the first embodiment.

  In such an aspect, there is an interval between the guide points, and the region introduction is performed in a section where the travel guidance is not performed for a while. Therefore, the user is less likely to fail to move according to the movement guidance due to the introduction of the area.

(2) In addition, when generating route data, the route guide does not determine the place to introduce the region, and after the route guidance is performed, a predetermined time (for example, 5 seconds) has elapsed. Further, it is possible to adopt a mode in which the region introduction is performed at a time that is a predetermined time (for example, 10 seconds) or more before the predicted time for performing the next movement guidance.

  Note that the calculation of a time that is a predetermined time or more before the predicted time when the next movement guidance is performed can be calculated based on the distance to the next guidance point and the moving speed at that time. Further, the calculation of a time that is a predetermined time or more before the predicted time when the next movement guidance is performed can also be calculated based on the distance to the next guidance point and the average movement uniqueness of the route section. In such an aspect, it is preferable to introduce the region before entering the specific region to be introduced or at the earliest possible time after entering.

  Even in such an aspect, the user can reduce the possibility that the user will be distracted by the area introduction and fail to move according to the movement guide. Moreover, since the timing for introducing the region can be determined in consideration of the actual traveling speed, it is possible to more reliably prevent the movement guide and the region introduction from approaching each other.

(3) In the above embodiment, the guide point is determined when the route is determined (see step S210 in FIG. 4). However, the guide point can be determined at another timing. However, the guidance point is preferably determined before the introduction point is determined (see step S234 in FIG. 4).

B4. Modification 4:
In the said Example, specific area | region A1-A3 with many delicious ramen shops was demonstrated to the example. And in the said Example, the specific area | region about one reduced scale was demonstrated (refer FIG. 2). However, a plurality of types of specific areas can be prepared.

  For example, the region database 186 can hold a plurality of types of information on specific regions according to the scale of the map when displaying a route on the display panel 202 of the mobile phone 200. For example, the specific area corresponding to the first scale showing a narrow range on the display panel 202 and the specific area corresponding to the second scale showing a wide range on the display panel 202 may be different. For example, as a specific area corresponding to the first scale, a plurality of specific areas are held, and as a specific area corresponding to the second scale, a specific area including the plurality of specific areas is held. You can also

  With such an aspect, it is possible to prevent the display from becoming complicated when the specific area is displayed on the map. The route search server 100 preferably includes the information on the plurality of types of specific areas in the route data transmitted to the mobile phone 200. And as for the mobile phone 200 as an output terminal, it is preferable to change the specific area | region displayed according to the reduced scale of a map.

  In addition, the area database 186 can hold information on the specific area according to the route moving means. The area database 186 can hold, for example, specific area information for walking, specific area information for bicycles, and specific area information for cars.

  And in the section which should be moved with the 1st movement means (for example, a walk and a bicycle) which is not suitable for long-distance movement, a neighborhood area is chosen from a plurality of specific areas where each specific area was set small (finely). In the section to be selected and moved by the second moving means (for example, an automobile) suitable for moving over a longer distance than the first moving means, the specific areas are set larger (roughly). A neighboring region can be selected from the list.

  At this time, it is preferable to change the distance as a reference for determining whether or not the vehicle is “near” the route according to the moving means. That is, in the section to be moved by the first moving means that is not suitable for long-distance movement, the distance used as a reference for determination of the neighborhood is shortened and moved by the second moving means suitable for long-distance movement. In the power section, it is preferable that the distance serving as a criterion for determining the neighborhood is longer.

  If the route includes a section to be moved by different moving means (see step S210 in FIG. 3), the route search server 100 adds a specific area corresponding to the moving means in each section to the route data in step S230. Include information. According to such an aspect, it is possible to introduce a specific area in the route guide within a range that is easy to detour according to the moving means.

B5. Modification 5:
In the above embodiment, the introduction of the area on the route using the expressway has been described. However, similar processing can be performed when a route including a section to be moved is determined using a transportation facility such as a train that stops at a predetermined station.

  For example, in step S226 of FIG. 4, a specific area that overlaps with a predetermined range near the boarding station and the getting-off station on the route is selected, and a predetermined range near the boarding station or the getting-off station is selected even in the specific area near the route. A specific area that does not overlap with is not selected. As a result, in the route guide, the area introduction is performed for the specific area near the boarding station and the getting-off station, and the area introduction is not performed for the specific area near the middle section.

  By adopting such a mode, it is possible to avoid introducing a specific area that cannot be detoured or a specific area that is less likely to detour when the route guide is provided. For this reason, the user is not bothered by the introduction of unnecessary specific areas during the route guide.

  In addition, in step S226 of FIG. 4, it can also be set as the aspect selected also about the specific area | region which overlaps with the predetermined range of the vicinity of the stop station between a boarding station and an alighting station. In such a mode, in the route guide, in addition to the boarding station and the getting-off station, the area introduction is also performed for a specific area near the stop station on the way. If it is set as such an aspect, the user can drop off on the way and can take a detour.

  Similarly, when using an expressway, a specific area in the vicinity of the interchange on the way between the interchange on the expressway and the interchange getting off the expressway can be introduced. If it is set as such an aspect, the user can get off at the interchange in the middle of a highway, and can take a detour.

B6. Modification 6:
In the above-described embodiment, when the date when moving the route is outside the time when the characteristics of a specific area are exhibited, the area information server 180 has the specific area in the vicinity of the path. Even if it exists, the specific area is not selected (see step S310 in FIG. 3). However, the selection of the specific area based on the date can also be performed by the route search server 100 in the process of step S226 in FIG.

B7. Modification 7:
In the said Example, the enjoyment of a specific area | region was what would be preferable for users, such as delicious ramen and beautiful autumn leaves. However, the enjoyment of a specific area can also include what appears to be undesirable for the user. For example, it is also possible to introduce a “specific area with many traffic accidents” or a “specific area with many traffic jams”. With such an embodiment, the user can drive the car more carefully, park on the road, stop turning to the side road, and pass through the specific area safely and in a short time.

  In addition, the specific area introduced to the user can be selected by the user selecting a gift. That is, among the enjoyments in a specific area for which the area database 186 holds data, the enjoyment that the user does not want to be introduced is input in advance to the route search system via the command input unit 206 of the mobile phone 200. (See FIG. 1). Then, the route search server 100 receives, from the mobile phone 200, information on the enjoyment that the user does not want to be introduced.

  When the route search server 100 inquires the region information server 180 about information on a specific region in the vicinity of the route (step S220 in FIG. 3), the route search server 100 sends information on the items that the user does not want to be introduced to the region information server 180. Send. In step S <b> 310, the area information server 180 determines a specific area in the vicinity of the route except for a specific area corresponding to an enjoyment that the user does not want to be introduced. If it is set as such an aspect, a user will not be provided with the information of the specific area | region about the unwanted enjoyment. Note that the route search server 100 or the mobile phone 200 may perform selection of a specific area based on a gift that the user does not want to be introduced instead of the area information server 180.

B8. Modification 8:
In the above-described embodiment, data representing the position of the guidance point, such as image data and audio data used for moving guidance, is included in the route data when the route data is generated. However, not all of the data is included in the route data in advance, and at least a part of the data is acquired from the route search server 100 or another server as the current position advances on the route. It can also be set as an aspect.

B9. Modification 9:
In the above-described embodiment, after the display DM1 (see FIG. 6) regarding the enjoyment in the specific area is performed, the display DM1 is displayed when an instruction from the user is not input to the mobile phone 200 for a predetermined time. Disappear. At this time, a predetermined display (corresponding to B01 in FIG. 6) for presenting individual places where the user can enjoy the enjoyment is displayed on the display panel 202 even after the display DM1 is no longer displayed. Is preferred. This display need not be the same display as the button B01.

  Such a display is preferably not displayed on the display panel 202 when the current position leaves the specific area or after the current position leaves the vicinity of the specific area. The user can cause the display panel 202 to display information on a place where the user can enjoy the enjoyment of the specific area by clicking on the display (see FIG. 8).

B10. Modification 10:
In the said Example, if button B01 is clicked (refer FIG. 6), the list | wrist of the place where a user can enjoy the enjoyment of a specific area | region will be shown (refer FIG. 8). A plurality of lists are displayed when the current position is in or near a region where a plurality of types of specific regions overlap. In such a case, for example, there are a plurality of indications related to the enjoyment (see display DM1 in FIG. 6) such as “This area has many delicious ramen shops. This area has beautiful autumn leaves.” It can be a display that provides the type of information. Then, when the button B01 is pressed, a list of ramen shops and a list of points with beautiful maple trees are presented. If it is set as such an aspect, a user's convenience can be improved more.

  In addition, when the display regarding enjoyment is the display which provides the information regarding multiple enjoyment, the button for showing each place where a user can enjoy enjoyment is displayed for every enjoyment, You can also In such an aspect, when each button is pressed, a corresponding list of received items is displayed.

  Moreover, in the said Example, when button B01 (refer FIG. 6) is clicked, the list | wrist of the place where a user can enjoy the enjoyment of a specific area | region is shown. However, the information on the place where the user can enjoy the enjoyment can be provided by other methods. For example, by displaying on the display panel 202 an image in which a place where the user can enjoy the enjoyment is plotted on a map, information on the place where the user can enjoy the enjoyment can be provided.

  In such an aspect, it is preferable that the user can select a point where the enjoyment displayed on the map can be enjoyed by operating the command input unit 206. The user can select each point displayed on the map and obtain detailed information. In addition, when there is a current position in an area where a plurality of types of specific areas overlap or in the vicinity thereof, it is preferable that each point where the enjoyment can be enjoyed is plotted on a map with a mark of a different color or shape.

B11. Modification 11:
In the above embodiment, the route search system includes the route search server 100, the map server 150, the area information server 180, and the mobile phone 200 as its components. However, a mobile terminal that is carried by the user and that includes a GPS unit and a display may be provided with the functions of the route search server 100 and the map server 150. Furthermore, the function of the area | region information server 180 can also be provided in a portable terminal. Further, the route search server 100 and the map server 150 may be the same server. The area information server 180 may be the same server as the route search server 100.

  That is, the route search system as a guide device may be one device in which each component is accommodated in one housing. In addition, the route search system can be configured as two or more devices whose constituent elements are connected to each other by a data communication line. For each function such as a function for generating route data and a function for selecting a specific area, one or more arbitrary functions can be assigned to each device. Each function may be realized by one device, or two or more devices may be realized in cooperation. In an aspect in which two or more components are connected by a communication line, the output unit that outputs information to the user is preferably carried by the user.

B12. Modification 12:
In the above embodiment, a part of the configuration realized by hardware may be replaced with software, and conversely, a part of the configuration realized by software may be replaced by hardware. For example, a part of the function of the application software 212 (FIG. 1) can be executed by the control circuit.

  A computer program for realizing such a function is provided in a form recorded on a computer-readable recording medium such as a floppy disk or a CD-ROM. The host computer reads the computer program from the recording medium and transfers it to the internal storage device or the external storage device. Alternatively, the computer program may be supplied from the program supply device to the host computer via a communication path. When realizing the function of the computer program, the computer program stored in the internal storage device is executed by the microprocessor of the host computer. Further, the host computer may directly execute the computer program recorded on the recording medium.

  In this specification, the host computer is a concept including a hardware device and an operation system, and means a hardware device that operates under the control of the operation system. The computer program causes such a host computer to realize the functions of the above-described units. Note that some of the functions described above may be realized by an operation system instead of an application program.

  In the present invention, the “computer-readable recording medium” is not limited to a portable recording medium such as a flexible disk or a CD-ROM, but an internal storage device in a computer such as various RAMs and ROMs, An external storage device fixed to a computer such as a hard disk is also included.
