Description

  The present invention relates to a mobile terminal device, a control program thereof, and a server.

  The development of wireless communication technology and device technology has been remarkable in recent years, and small mobile terminal devices such as mobile phones have become widespread as communication tools carried by individuals. Its functions are diverse, such as phone calls, e-mail, web browsing, camera photography, music playback, position detection (GPS), and the like.

  If the web browsing function of such a mobile terminal device is used, the user can actively input the name or keyword of a specific destination and search for and browse necessary information.

  However, it is not originally planned in stores and commercial facilities by automatically providing information to mobile terminals that have entered the area, regardless of such aggressive instruction operations by the user. It would be preferable if customers could be attracted.

  From such a point of view, various techniques for providing information related to stores and facilities around the current position using a mobile terminal device have been proposed.

  Non-Patent Document 1 is not a service for mobile terminal devices, but by specifying a station name as “XX station.jp.” As a URL address to be browsed on the web, various stores and facilities around the station The technology which provides the option information which can select advertisement, advertisement, and usage information, etc. is disclosed.

Patent Document 1 discloses a technique for accessing a predetermined portal site from a mobile phone, sending it to a user context information server such as location information and time of the mobile phone, and receiving and displaying information corresponding to this from the server. is suggesting. However, the information search based only on the position information and the user context information has a wide range of hit items, and is not suitable for browsing on a mobile phone. Therefore, the server extracts a keyword from information input in advance in the schedule book or the like by the user, and extracts appropriate information (advertisement) associated with the position based on the keyword.
JP 2001-236368 A Internet <URL: http: // Shinjuku Station. jp />

  Even if web browsing as described in Non-Patent Document 1 can be performed by the mobile terminal device, the user needs to input an individual station name, and a user who is resistant to such complicated operation uses such a service. There is a high possibility of not. The information provided by this service is various information around a certain station, and includes a lot of unnecessary information. That is, since the user's purpose in a certain place is various, the presented information is not necessarily information that matches the user's purpose and interest. In particular, for advertisement / advertisement information, information that does not match the user's purpose or the like is ineffective and provides annoying information for the user. For this reason, in the case of a service that provides information without being actively requested by the user, if the service is rejected by the user, the service cannot be realized.

  According to the technique described in Patent Document 1, it is possible to provide information according to the user's situation. For this purpose, it is necessary to transmit the user's schedule information in the terminal to the server for use. It cannot be used for users who have not entered such information. Further, the schedule information is personal information, and even a user who performs input may be hesitant to use it externally.

  The present invention has been made in such a background, and the purpose of the present invention is to provide a user's destination in a certain place without performing complicated operations such as inputting information on the place where the user is or where he / she will be visiting.

Send to. Instead of using the acquired weight map information as it is, it is possible to make a web request based on condition information reflecting the user's attributes and the current situation.

  Further, when moving from the first place to the second place, the condition information generating means combines the weighting map used in the first place and the weighting map corresponding to the second place according to a predetermined rule. The predetermined condition information can also be generated based on the resultant weighting map. Thereby, even if it is the same place, it becomes possible to reflect in the request | requirement of web information the movement history which came to the place from where. Alternatively, it is possible to correct the weight point based on the direction of movement.

  At least a plurality of locations that can serve as a base point in a certain area, a base point distribution map storage unit that acquires and stores a base point distribution map that defines position information and identification information from the outside, and the weight map acquisition unit stores the current position It may be determined whether it is within the vicinity area of any place in light of the base point distribution map. By acquiring the base point distribution map from the outside, it becomes easy to recognize the existence of base points around the current position and determine whether the current position belongs to the base point.

  The mobile terminal device may further include history information storage means for storing history information of user movement between the plurality of places, and means for transmitting the history information to the server. As a result, the server can acquire actual user movement history information and use it to update the weighted map of the area.

  The present invention can also be understood as a control program for a mobile terminal device and a recording medium storing the program.

  A server according to the present invention is a server that provides information to a mobile terminal device via a communication network, and at least among a plurality of places in a certain area, each of the other points with respect to the base point A weighting map that defines weight points representing the degree of association of places is stored for each place, weight map storage means storing the current position information from the mobile terminal device, and a weight map corresponding to the current position is extracted.

These functional units are realized by software processing of each hardware unit and / or CPU shown in FIG.

  The position information acquisition unit 121 acquires information on the current position of the mobile terminal 100 by the function of the GPS reception unit 109. The base point distribution map acquisition necessity determination unit 122 determines whether or not the base point distribution map needs to be acquired based on the current position change information and the like, and requests the base point distribution map of the predetermined area from the server 200 when necessary. The base point distribution map accumulation unit 123 is a part that stores the acquired base point distribution map in a storage device such as the RAM 102 or the flash memory 108. The base point / sub base point setting unit 124 determines whether or not the current position belongs to the base point and whether the current position belongs to the base point (that is, the base point reached after starting the base point (ie, the sub base point)) by referring to the base point distribution map.

The weighting map storage unit 126 is a part that stores the received weighting map in a storage device such as the RAM 102 or the flash memory 108. However, the time information may not be sent from the terminal to the server, but may be used by checking the current time on the server side.

  The weighting map combining unit 127 combines weighting maps at the sub-base points. An example of this synthesis will be described later. The condition information generation unit 128 is a part that generates condition information by analyzing a weighting map (including a composite weighting map). The “condition information” is information used as a condition for extracting appropriate web information in the web information providing server 200c. Details of this will also be described later. A Web information request is transmitted to the server 200 together with the condition information.

  The Web information storage unit 129 stores the Web information received from the server 200 in a storage device such as the RAM 102 or the flash memory 108.

The base point distribution map providing unit 221 searches the base point distribution map DB 222 in response to a request from the mobile terminal 100, and provides the mobile terminal 100 with the latest base point distribution map of the area. The weighting map providing unit 223 searches the weighting map DB 224, extracts a weighting map corresponding to the base point and time (time zone to which the point belongs), and transmits the weighting map to the mobile terminal 100. The Web information extracting / providing unit 225 extracts corresponding Web information from the Web information DB 226 based on the condition information from the mobile terminal 100 and transmits it to the mobile terminal 100.

Next, the basic operation of the information providing system in FIG. 1 will be outlined with reference to FIG.
(1) The situation where the user of the mobile terminal 100 arrives at S station by train is taken as an example. As a premise of this information providing service, the mobile terminal 100 acquires the base point distribution map 21 from the base point distribution map server 200a.
(2) When the station arrives at the S station, the S station is set as a base point automatically or based on an instruction from the user based on the base point distribution map 21.
(3) The mobile terminal 100 accesses the weighting map management server 200b and acquires the weighting map 23 of this base point.
(4) The mobile terminal 100 generates condition information based on the weighting map 23 and other necessary information and transmits it to the Web information providing server 200c. A method for generating the condition information will be described later.
(5) The web information providing server 200c extracts appropriate web information 25 based on the received condition information and transmits it to the mobile terminal 100. The web information 25 is typically displayed as a web page including a plurality of items in which links to specific URLs are set, as shown on a screen 250. The Web information may include summary data for each item in addition to a plurality of URLs. By selecting and instructing any item, the user can acquire and view further detailed information on the item from the Internet or the like.
(6) It is assumed that the user reaches another landmark (for example, department store A) from the S station as the user moves, and passes through the landmark toward another landmark (for example, arena C). Such a fact is found by comparing the change in the current position of the mobile terminal 100 with the base point distribution map 21. At this time, the department store A, which is the landmark that has arrived next to the S station, is set as a sub-base point, and the weight map 23 of the department store A is acquired from the weight map management server 200b.
(7) The mobile terminal 100 updates the condition information and transmits it to the Web information providing server 200c.
(8) The mobile terminal 100 reacquires Web information from the Web information providing server 200c and updates the display. As a result, the information provided on the display screen 250 automatically changes as the user moves.

  A specific example of the base point distribution map will be described with reference to FIG. FIG. 6A schematically shows a base point distribution map 21 in a certain area (for example, around Shibuya, around Shinjuku, etc.) on a two-dimensional plane. A small black circle in FIG. 6A represents the base point 31. A base point setting area 32 is defined within a certain distance range around the base point. The base point setting area 32 has a predetermined range for grasping the position of the base point. A weighting map 23 is prepared for each base point 31. It is also possible to prepare the weighting map 23 in common for positions that do not belong to any base point setting area 32 within a certain area.

  FIG. 6B shows the base point distribution map 21 as data in a table format. The information held by the base point distribution map 21 includes “landmark ID” that is information for uniquely identifying each landmark, the “name” of the landmark, and a position represented by longitude and latitude. . In addition, if necessary, other items may be held in the base point distribution map 21.

  FIG. 7 is an explanatory diagram of a weighting map. FIG. 7A shows a landmark arrangement around the base point indicating the positional relationship of main landmarks around the base point. FIGS. 7B and 7C illustrate weighting maps 23 for time zone 1 (for example, daytime) and time zone n (for example, nighttime) corresponding to FIG. 7A, respectively. The positions of figures ○, □, etc. in FIGS. 7B and 7C correspond to positions on the map, and their sizes reflect weight points. That is, the larger the weight point, the larger the size. The shape corresponds to the genre of the landmark. As can be seen from FIGS. 7B and 7C, the content of the weighting map around the same base point may vary depending on the time zone.

  Note that the weighting map 23 shown in FIGS. 7B and 7C visually shows the content of the weighting map for easy understanding, and is actually represented as data in a predetermined data format. . FIG. 8A shows a data format example of the weighting map, and FIG. 8B shows a specific example thereof. In the weighting map 23, a major “landmark” and its “metadata” around the base point are defined for each of a plurality of time zones. “Metadata” includes “weight point”, “genre” to which the landmark belongs, “name” of the landmark, “business hours” such as the holiday / business hours of the landmark, and the main customers of the landmark Includes “subjects” such as gender and age group. The weight point is statistical probability data that moves from the base point to the landmark (that is, the degree of possibility of movement from the base point to each other landmark).

The condition information is generated based on landmark identification information and metadata included in the acquired weighting map. For example, the following information can be used as the condition information.
(1) Landmark ID extracted from top n (n is multiple) from the one with the largest weight point
(2) Genres extracted from the top n items with the largest weight points (3) When weight points are aggregated for each genre, the top n categories with the largest weight points

  Further, when generating the condition information, the information set in advance in the terminal may be checked against the information of the weighting map, and the corresponding landmark may be selected to generate the condition information. For example, the preset information is attribute information such as a genre of a landmark (restaurant, department store, etc.), preference, personal information (gender, age, etc.), and a landmark having metadata corresponding to these. Condition information can be generated by extraction with priority. In addition, since a weighted map is prepared according to the time zone, it is considered that the landmark whose current time is outside business hours is not included in the weighted map. Can be excluded when generating the condition information.

  FIG. 9 shows several determination schemes for the weight map.

  FIG. 9A shows a weighting map determination scheme # 1. This is a case where the weighting map obtained based on the current base point (including the sub base point) and the current time is used as the weighting map, regardless of whether the current position is the base point or the sub base point.

  FIG. 9B shows a weighting map determination scheme # 2. This is based on a predetermined condition between a weighting map (including a composite weighting map described later) obtained at the immediately preceding base point (including a sub base point) and a current weighting map obtained based on the current sub base point and the current time. This is a case where a synthesis weight map obtained by synthesis is used. By reflecting the contents of the weighting map used immediately before the user's movement route in the current weighting map (correcting the weight points), a weighting map reflecting the movement history can be generated. That is, even if the landmark position is the same, the content of the composite weight map differs depending on where it comes from. For example, distributing restaurant information around S station uniformly to a mobile terminal user at S station is beneficial for those who will be visiting from now on, but it will be rejected for users who arrive at S station because they want to return. It becomes annoying. In the present embodiment, such a problem can be dealt with by using a composite weighting map reflecting the movement history.

  FIG. 9C illustrates a weighting map determination scheme # 3. This is similar to FIG. 9B, but in addition to the case of FIG. 9B, the traveling direction information (whether each landmark is at a predetermined position in relation to the traveling direction). Considering this, a composite weighting map is generated. In this case, for example, a correction that lowers the weight point relative to the landmarks behind the traveling direction as the “predetermined position” relative to the other landmarks is performed. With this configuration, even if the landmark position is the same, the content of the composite weight map differs depending on where it is from and where it is going.

  FIG. 10 shows how the weighting map (synthetic weighting map) changes as the user moves in the weighting map determination scheme # 2 shown in FIGS. . The weighting map 0 at the first base point is used as it is. At the next sub-base point 1, a weighting map 1a is generated by synthesizing the weighting map 1 and the weighting map 0 obtained at this position and time. At the next sub-base point 2, the weighting map 2a is generated by synthesizing the weighting map 2 obtained at this position and time and the previous combined weighting map 1a. At the next sub-base point 3, a weighting map 3a is generated by combining the weighting map 3 obtained at this position and time with the previous combined weighting map 2a. Such processing is continued until the base point is reset.

  FIG. 11 shows a two-dimensional representation of the weighting map composition. Although the weighting map includes surrounding landmarks centered on the current position, FIG. 11 shows only the first quadrant portion centering on the current position (black circle in the figure) for convenience.

  11A is a weighting map for the S station base point, FIG. 11B is a weighting map for the department store A, which is the next sub base point, and FIG. 11C is a weighting map for both FIGS. 11A and 11B. Are respectively represented by combining weighting maps obtained by combining. As can be seen from the figure, there is no weight point at the user's current position (small black circle) (ie, 0), so there is no size-change figure at that position in the figure. The alphabetic characters in parentheses attached to the names of the landmarks in the figure indicate the weight points. The weight point notation (b3 = b1 | b2) in the composite weight map in FIG. 11C indicates that the weight point b3 is obtained by combining the weight points b1 and b2. A typical example of the synthesis method is to take an average value, but this is not restrictive. Further, as a combination when the traveling direction is taken into account, the landmark weight points on the opposite side to the traveling direction may be reduced. The calculation formula is, for example, x3 = (x1 + x2) / 3. At the same time, the weight points of landmarks in the traveling direction may be increased. The calculation formula is, for example, x3 = x1 + x2.

  By combining weighted maps in consideration of such movement trajectories, the weight points of landmarks visited or passed immediately before can be reduced, or the weight points of landmarks in the direction of travel, for example, can be reduced. Thus, it is possible to compensate for the weight points of the static weight map according to the movement situation of the user.

  Next, the operation of the information providing system in the present embodiment will be described with reference to a flowchart.

  FIG. 12 shows an initial process in the mobile terminal 100 regarding the operation of the present embodiment. The mobile terminal 100 is always in a state where it can receive this information providing service after the power is turned on, or a state where the user can receive this information providing service after performing a predetermined instruction operation. It is arbitrary.

  Also, changes related to movement of the mobile terminal 100 are always monitored, and when there is a change related to movement, the information providing service is ready. When the change related to movement stops, the information providing service cannot be received. Various functions of the mobile terminal 100 may be automatically controlled so as to be in a state. That is, it is possible to monitor a change in movement of the mobile terminal and control at least one of driving and stopping of the weight map acquisition unit, the transmission unit, the reception unit, and the display unit according to the change in movement. Here, the “change related to movement” may include a change in moving speed and moving speed in addition to a change in current position. The change in the moving speed of the terminal can be calculated based on the periodic position monitoring result by GPS. However, a separate acceleration sensor (not shown) is provided to directly measure the acceleration. Also good.

  In the process of FIG. 12, the mobile terminal 100 monitors the position information acquisition timing in order to perform the process at a predetermined frequency (for example, every minute) (S11). When it is time to acquire position information, the current position is detected (S12). Therefore, it is confirmed whether it is necessary to acquire a base point distribution map (S13). In this confirmation, when the mobile terminal enters the information provision reception mode, or when the mobile terminal moves more than a predetermined distance and the base point distribution map to which the same position belongs does not exist in the terminal, “acquisition required” Judge. At this time, the base point distribution map server 200a is accessed to acquire the base point distribution map (S14).

  Once the base point distribution map is acquired for a certain area, it can be used continuously unless it is upgraded. Therefore, if the base point distribution map of the current position is needed, if it is already stored in the mobile terminal, the version is sent to the server, the presence or absence of version upgrade is confirmed, and the base point distribution map is downloaded only when necessary. You may make it do.

  In this example, the base point distribution map is automatically acquired by the mobile terminal according to a predetermined condition. However, the base point distribution map of the area may be acquired in accordance with the user's instruction operation. Also in this case, it is preferable to acquire a new base point distribution map after confirming version upgrade.

  FIG. 13 shows a flowchart representing main processing of mobile terminal 100 in the present embodiment. This process is executed independently of the process of FIG. 12 on the premise of the process of FIG.

  The current position of the mobile terminal is monitored, and it is confirmed whether or not the current position matches a predetermined base point setting condition (S21, Yes). The base point setting condition is a condition for determining whether or not the current position may be used as a base point. For example, when the GPS receiver changes from a position undetectable state to a possible state (for example, a building with low satellite radio wave reception sensitivity). When you move from inside to outside), when high-speed movement changes to low-speed movement and a certain time has passed (for example, when you get off the train), when you start moving from a stationary state, etc. Check the current position against the light and check if the current position is within the base point setting area of any landmark. If within any base point setting area, the landmark position is set as the base point (S22).

  The base point information is recorded in the storage device as movement history information. The base point may be set even when there is an explicit instruction operation by the user.

  Furthermore, as a trigger for setting the base point, in the case of a mobile terminal having a non-contact IC card function, it is determined that movement has started, for example, when the vehicle goes out of the ticket gate, based on the information of getting off the vehicle using the function. Thus, the base point can be set.

  Next, the base point and current time information are transmitted to the server, and the corresponding weighting map is downloaded (S23). As described above, the time may be determined by the server. Further, the condition information to be transmitted to the Web information providing server is generated as described above based on the weighting map or the like (S24). The generated condition information is sent to the Web information providing server, acquired from the Web information providing server, processed as necessary, and then displayed on the display unit (S25).

  Thereafter, the processes in steps S27 to S32 are repeated until the base point reset process is required (S26). The base point reset process is a process for stopping the update of the sub base point. Specifically, the stop condition is, for example, when the user changes from a low speed movement to a high speed movement (for example, when getting on a train or a bus). For example, when an explicit stop instruction operation is performed. Furthermore, when the current position stops moving for a certain period of time or when the GPS function stops working for a certain period of time, the stop condition may be added. Increasing the stop condition increases the possibility that the chain of sub-base points is interrupted. In this case, the last sub-base point can act as a new base point.

  In the case of a mobile terminal having the above-described contactless IC card function, for example, it is determined that the movement has stopped when entering the ticket gate based on the vehicle ride information using the function, and the base point can be reset. Is possible.

  When it is determined that the base point reset process is necessary, the base point reset process is performed, the reset position (end point) is added to the movement history (S33), and the movement history information from the base point to the end point is transmitted to the weighted map management server 200b ( S34). Thereafter, until this process is ended by an explicit end instruction or the like by the user (S35), the process returns to step S21 and the above process is repeated.

  In step S27, the monitored current position is checked against the base point distribution map, and it is determined whether setting of the sub base point is necessary (S27). If the current position does not belong to any base point setting area, it may belong to the “other” base point area shown in FIG. If it is determined that setting of the sub-base point is necessary, information on this sub-base point is added to the movement history (S28). Further, a weighting map corresponding to the sub-base point and the current time is downloaded (S29). Therefore, as described above, a new weighting map by synthesis is constructed as necessary (S30). Based on this new weighting map, the condition information is generated as described above and transmitted to the Web information providing server (S31). Next, Web information is acquired from the Web information providing server, processed as necessary, and then displayed (S32). Thereafter, the process returns to step S26.

  FIG. 14 shows an example of information provision in a specific time-series situation where the user of the mobile terminal 100 uses this information provision service. However, this example is for better understanding of the present embodiment, and the present invention is not limited to such a specific operation.

  FIG. 14A shows a situation 41 in which the user takes a train with a mobile terminal, arrives at S station at 12:00, and starts moving in the direction of department store A. FIG. At this time, the base point is set at S station, and the weighting map 23a corresponding to the base point and the current time is downloaded to the mobile terminal. In addition, Web information items such as a screen 51 are provided based on the condition information generated according to the weighting map 23a. The markup language document constituting such page data can be generated by either the terminal or the server. In this example, an option list including items corresponding to main landmarks of the weighting map 23a is presented. On the screen 51, one of the options is highlighted with a cursor (or reverse / highlight). In this example, the display of a plurality of options is displayed as having the highest importance from the bottom, and the cursor is initially set at the bottom option. The cursor can be moved to another option by a user instruction operation on the operation unit 107. In accordance with a predetermined instruction from the user, an option with the current cursor is selected and its detailed information is displayed. The storage location of the detailed information is in the terminal or an external server.

  FIG. 14 (b) shows a situation 42, which is performed following the situation 41, by the user passing through the department store A and moving toward the arena F at time 12:10. At this time, department store A is set as a sub-base point, and weight map 23b corresponding to department store A and the current time is downloaded. Also, a composite weight map is generated based on the weight map 23a for the S station and the weight map 23b for the department store A, and Web information is provided based on the condition information corresponding to the composite weight map. This Web information is displayed as a screen 52, for example. The information “department Ainfo” relating to the department store A displayed on the screen 51 has disappeared on the screen 52 at this point. This is because it is presumed that the user has no interest in the department store A due to the passage of the department store A, and this is reflected in the weighting map.

  FIG. 14 (c) shows a situation in which the user moves to “another area” where the base point does not exist within a predetermined distance range of the current position and moves toward the arena F direction at time 12:20 following the situation 42. 43 is shown. At this time, “other area” is set as the sub-base point, and the weighting map 23c corresponding to the sub-base point is downloaded. Also, a composite weight map is generated based on the composite weight map of S station and department store A and the weight map 23c of “other areas”, and Web information is provided based on the condition information corresponding to this composite weight map. This Web information is displayed as a screen 53, for example.

  FIG. 14D shows a situation 44 in which the user arrives at a restaurant in another area (not registered as a base point) at time 12:25 following the situation 43. At this time, the state where the current position does not change continues for a predetermined time or longer by staying in the restaurant. Thereby, the condition of step S13 in FIG. 13 is satisfied, and the base point reset process is performed. That is, the current position becomes the “end point”. From the S station that is the base point, the department store A that is the sub base point and other areas, and the position information of the end point are transmitted (uploaded) to the weighted map management server 200b as movement history information.

  The weighting map management server 200b updates the weighting map in the same area based on the movement history information. If the movement histories of many users are accumulated in this way, the reliability of the statistical data reflected in the weighting map is improved.

  In this example, the case of using the weighting map determination scheme of FIG. 9B is shown, but other determination schemes may be used.

  FIG. 15 shows another example of information provision in which the user of the mobile terminal 100 uses this information provision service.

  As another example, the situation 45 is a situation in which the user finishes eating and drinking at the store in the eating and drinking area I at 23:00, leaves the store, and starts moving toward the S station. At this time, “food area I” is set as the base point, and the weighting map 23d corresponding to the time 23:00 is downloaded. The weighting map 23d in this figure shows only the first quadrant portion centered on the current position for convenience.

  Furthermore, the information provision based on the condition information corresponding to the weighting map 23d is received. In this example, since the base point is other than the station and the time is 23:00 in the weighting map 23d, the S station, the accommodation area H, the club K, the movie theater J, etc. appear as major landmarks with large weight points. ing. Web information corresponding to the current position and time zone is displayed as a screen 54, for example.

  In the embodiment described above, as clearly shown in FIG. 4, the mobile terminal performs the determination of necessity of setting the base point and the sub base point, the synthesis of the weighting map, the generation of the condition information, and the like. It can also be executed on the server 200 side. FIG. 16 shows the system function sharing configuration in this case.

  In this configuration, in addition to the configuration in FIG. 4, a base point distribution map acquisition necessity determination unit 232, a base point distribution map storage unit 233, a base point / sub base point setting unit 234, a weight map confirmation unit 235, and a weight map storage are added to the server 200 side. A unit 236, a weighting map synthesis unit 237, a condition information generation unit 238, a base point reset determination unit 242, and a movement history information storage unit 243. These functional units 260 need to be secured for each mobile terminal 100 using this information providing service (that is, for each user). Therefore, the number of functional units 260 dynamically changes depending on the number of mobile terminals that are using the service. In this configuration, the mobile terminal 100 periodically detects the current position and notifies the server 200, and in response to this, the server determines the status of the mobile terminal, and the mobile terminal 100 performs the same as described above. Web information is provided. Instead of reducing the processing load on the mobile terminal 100, the processing load on the server 200 increases. As the above-mentioned “information preset in the terminal”, when this information providing service is provided to a registered user, information input at the time of user registration can be used.

  In addition, although not shown, a configuration in which only the condition information generation unit is moved to the server 200 side from the function of the mobile terminal in FIG. 4 can be considered as a compromise of the configuration in FIGS.

  The preferred embodiments of the present invention have been described above, but various modifications and changes other than those mentioned above can be made.

  For example, although the two-dimensional display of the weighting map is shown as an explanatory diagram, the two-dimensional display of the weighting map may be performed on the display unit so as to be switchable with the Web display screen or instead of the Web display screen. When performing two-dimensional display of the weight map instead of the Web display screen, each landmark figure may be associated with the corresponding URL.

  The weighting map may be prepared for each of a plurality of directions according to the moving direction after setting the base point. Specifically, when the base point is S station, a weighting map corresponding to each of different exits of the station (for example, the south exit and the north exit) may be prepared. For this purpose, for example, after the base point is set, it is possible to selectively acquire a weighting map relating to such a direction based on the moving position within a predetermined time.
