Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a functional configuration of a navigation device according to an embodiment of a destination candidate display device of the present invention.
The navigation device 1 is an in-vehicle device that is mounted on a vehicle that is a kind of mobile body and displays map information, route information to a destination (destination), and the like, and performs navigation processing that guides the user to the destination. . The navigation device 1 may not be provided in a vehicle, and may be a portable PND (Personal Navigation Device) or a mobile phone device, for example.

As shown in FIG. 1, the navigation device 1 includes a main control unit 11, a display control unit 12, a display unit 13, an input unit 14, a current location specifying unit 15, a voice processing unit 16, a communication unit 17, and a storage unit 18. Yes.
The main control unit 11 has a computer configuration including a CPU, a ROM, a RAM, and the like, and executes an operation program stored in the storage unit 18 to centrally perform various arithmetic processes and display processes. Function as. The display control unit 12 displays various screens such as a map and a route guidance screen on the display unit 13 under the control of the main control unit 11. The display unit 13 is a known display device such as a liquid crystal display or an organic EL (Electro-Luminescence) display, and displays various types of information to a user or the like.

  The input unit 14 is a device for inputting a user instruction, and inputs a user operation via a hard switch provided in the navigation device 1 or a touch panel provided on the display unit 13. When a user operation is input, the input unit 14 outputs information associated with the operation (for example, a touch panel detection position and command information) to the main control unit 11. Note that a transparent touch panel arranged on the display screen of the display unit 13 is applied as the touch panel, and detects an operation position, an operation amount, and the like of the user on the display screen. The current location specifying unit 15 specifies the current location by a known method based on information from a vehicle speed sensor, a gyro sensor, a GPS receiver, and the like.

  Under the control of the main control unit 11, the voice processing unit 16 emits a guidance voice for guiding the route of the user from the speaker. The communication unit 17 accesses a communication network such as the Internet via the wireless communication network under the control of the main control unit 11 and acquires various types of information from the service providing server 31 provided on the communication network. The storage unit 18 is a device that stores control programs and data necessary for the navigation device 1 to perform various processes. The main control unit 11 executes various processes included in a known navigation device such as a route search process and a route guidance process by executing a control program according to a user instruction.

  The route search process is a process of searching for a route from a predetermined point such as the current location to the destination, and the route guidance process displays a map image including the current location on the display unit 13 and provides route guidance from the current location to the destination. This process is performed by display or sound. The destination can be searched from a telephone number or an address input by the user.

  Further, in the present embodiment, a control program for performing destination candidate display processing is stored in the storage unit 18 as a function for assisting the user in creating a drive plan. As shown in FIG. 1, the storage unit 18 of the present embodiment can be a destination candidate with a program / map storage unit 18 </ b> A that stores a control program, map information, and the like for executing various processes including a destination candidate display process. A facility data storage unit 18B that stores facility data D1 (destination candidate data) describing facility information and an image data storage unit 18C that stores image data for destination candidate display processing and the like are provided.

The facility data D1 includes POI (Point Of Interest) data DA that describes the location, name, telephone number, address, and the like of a facility that can be a destination candidate, and a facility classification data DB that classifies the facility by a plurality of factors. Yes. The facility classification data DB may be either data provided from the service providing server 31 or data stored in advance.
In addition, the facilities are all those that can be destination candidates, and include not only artifacts such as buildings and equipment but also natural objects such as sightseeing spots, mountains, rivers, and the sea.

FIG. 2 is a diagram schematically illustrating an example of the facility classification data DB.
The facility classification data DB is data obtained by classifying facilities according to a plurality of predetermined factors, and the facility evaluation is described for each factor. Note that FIG. 2 shows only a part of data of a large number of facilities. For example, the shopping center includes only the data of “shopping center A” in FIG. Many shopping center data other than “A” are described.
As the factors, three factors including “purpose”, “cost”, and “who are going” are set.

  In the “object” factor, an evaluation of one of three stages consisting of a concept of a counter electrode composed of “static (relaxed)” and “motion (active)” and “another evaluation” is described. The factor “Relax” indicates that it can be relaxed, and “Active” indicates that it is active. In addition, the “other evaluation” of this factor indicates an evaluation of an intermediate state that is not limited to “static” or “moving” (for example, an evaluation that can deal with either “static” or “moving”). Yes. For example, FIG. 2 shows a case where “shopping center A” evaluates to “other evaluation” as a facility that can handle both “static” and “motion”. In addition, this evaluation and evaluation of other factors described below may be set as appropriate according to the information and reputation of the facility, the preference of the setter, etc., and may be changed as appropriate according to the renewal of the facility. You may do it.

  The “cost” factor describes the concept of “conservation” and “luxury” and the evaluation in one of three stages of “other evaluation”. "Saving" for this factor indicates low cost or high cost performance, "Luxury" indicates high cost, and "Other evaluation" is an intermediate state that is not limited to "Saving" or "Luxury" Shows the evaluation. In the example of FIG. 2, the case where any facility is evaluated as either “saving” or “luxury” is shown.

The “who is going to” factor describes the concept of a counter electrode consisting of “family” and “individual / friend”, and an evaluation in any of three stages of “other evaluation”. “Family” of this factor indicates that it is family-friendly, “Individual / friend” indicates that it is not family-friendly, and “Other evaluation” is not limited to “Family” or “Individual / friend” The evaluation of the state is shown. In the example of FIG. 2, “shopping center A” and “theme park A” are evaluated for families, and “golf course A” and “tennis court A” are evaluated for individuals / friends. In addition, “Shrine A”, “Mountain A”, and “Sea A” are shown as cases where “other evaluation” is evaluated as a facility that can handle both “family” and “individual / friend”.
The evaluation of each factor is arbitrarily determined by the manufacturer of the navigation device 1. For example, regarding the “cost” factor, a facility with a usage fee of less than 3,000 yen is evaluated as “saving” and a facility with a usage fee of more than 20,000 yen is evaluated as “luxury”. On the other hand, “objective” factors are evaluated based on a qualitative scale.

Next, the operation of the destination candidate display process will be described.
FIG. 3 is a flowchart of the destination candidate display process.
In the navigation device 1, first, the main control unit 11 prompts the user to select a reference point (step S11). When the current location is selected as the reference point, the main control unit 11 automatically inputs the current location specified by the current location specifying unit 15 as the reference point (step S12), and determines the current location as the reference point (step S13). . On the other hand, when a location other than the current location is selected, the main control unit 11 prompts the user to input a reference point (so-called manual input), and when input (step S14), determines the input point as the reference point. (Step S13).

Next, the main control unit 11 refers to POI data DA (first data) describing at least the positions of a plurality of facilities, and the movement time from the reference point is within a predetermined setting range (for example, within 3 hours). A facility is searched (step S15). As a method for calculating the travel time in this case, a method of calculating the travel time based on a linear distance from the reference point to the facility may be adopted from the viewpoint of shortening the calculation time, and the accuracy of the travel time is increased. A method may be adopted in which a recommended route from the reference point to the facility is searched from the viewpoint, and the travel time is calculated from the distance of the searched recommended route. Further, the selection of which method to use or the setting range may be configured to be arbitrarily set by the user.
The POI data DA used in step S15 is not limited to the POI data DA stored in the storage unit 18, but may be the latest POI data DA acquired from the service providing server 31 via the communication unit 17. In this case, the user or the like may arbitrarily set whether to use the POI data DA in the navigation device 1 or the external POI data DA.

  Next, the main control unit 11 classifies the facility extracted in step S15 for each factor based on the facility classification data DB (second data) in which the facility is classified by a plurality of predetermined factors (step S16). The facility classification data DB is not limited to the facility classification data DB stored in the storage unit 18 but may be the latest facility classification data DB acquired from the service providing server 31 via the communication unit 17. Moreover, you may comprise so that a user can set arbitrarily also about using facility classification data DB in the navigation apparatus 1 or using external facility classification data DB.

Subsequently, the main control unit 11 performs a mapping process for mapping the facility extracted in step S15 to a coordinate system simulating a radar chart based on the facility classification result (step S17). Then, the main control unit 11 displays the mapped image on the screen of the display unit 13 as a destination candidate image (step S18).
This mapping process sets coordinate axes corresponding to three factors for classifying facilities (“purpose”, “cost”, and “go to whom”), and these three coordinate axes are orthogonal to each other (X axis, Y axis). This is a process of forming a three-dimensional spherical coordinate system (axis, Z axis) and mapping the facility image to this spherical coordinate system. Hereinafter, an example of the destination candidate image will be described.

FIG. 4 is a diagram showing a three-dimensional display example of the destination candidate image.
In FIG. 4, reference signs F <b> 1 to F <b> 8 are images of the facility searched in step S <b> 15, and reference sign U <b> 1 is an image set as a reference point (an image showing the user's home in FIG. 4). For these images F1 to F8 and U1, image data stored in the image data storage unit 18C or image data appropriately acquired from the service providing server 31 is used.
Reference numeral F1 is an image showing the shopping center A in FIG. 2, reference numeral F2 is an image showing the theme park A in FIG. 2, and reference numeral F3 is an image showing the golf course A in FIG. Moreover, the code | symbol F4 is an image which shows the shrine A in FIG. 2, the code | symbol F5 is an image which shows the mountain A in FIG. 2, the code | symbol F6 is an image which shows the hot spring A in FIG. It is an image which shows the tennis court A in FIG. 2, and the code | symbol F8 is an image which shows the sea A in FIG.

As shown in FIG. 4, the X axis (horizontal axis) is a coordinate axis corresponding to “object”, and one (right side) indicates “movement (active)” with respect to the origin O (sphere center), and the origin O The other side (left side) indicates “still (relaxed)” with respect to (sphere center).
Further, the Y axis (vertical axis) is a coordinate axis corresponding to “cost”, and one (upper side) indicates “luxury” and the other (lower side) indicates “saving” with respect to the origin O.
Also, the Z axis (the axis in the depth direction) is a coordinate axis corresponding to “who goes”, and one (front side) indicates “family” with respect to the origin O, and the other (back side) indicates “individual / "Friend".

Furthermore, scales M1, M2, and M3 indicating the distance from the origin O are displayed in the destination candidate image. These scales M1, M2, and M3 correspond to radar spheres centered on the origin O. The scale M1 indicates the first reference position with the shortest distance from the origin O, and the scale M2 has the next shortest distance. The second reference position is indicated, and the scale M3 indicates the third reference position having the longest distance.
More specifically, the scale M1 indicates the position of the movement time in which the distance from the origin O is 1 h from the reference point, and indicates the boundary of the neighborhood area. Further, the scale M2 is a scale indicating the position of the moving time when the distance from the origin O is 2h from the reference point, and indicates the boundary of an area that is not a neighborhood but is not far away. The scale M3 indicates the position of the travel time when the distance from the origin O is 3 h from the reference point, and indicates the boundary of the outing area in the day trip range.

In this way, a coordinate system simulating a radar chart is constructed, and it becomes easy to intuitively recognize the distance from the reference point to the facility by the distance from the origin O. Moreover, the distance from the reference point set at the origin O to the facility can be recognized very easily by the three scales M1, M2, and M3 corresponding to the radar sphere, and the travel time to the facility can be recognized at a glance.
That is, in this coordinate system, the images F1 to F7 of each facility are positions where the distance from the origin O is the travel time from the reference point (user's home U1) to each facility, and each facility is It is displayed at a position determined by the coordinate axes X to Z of the factor to be classified.

By displaying this destination candidate image, the user can select a destination candidate facility based on the combination of the distance from the origin O and the three factors as selection criteria. Therefore, it is possible to easily select a destination candidate by a combination of favorite factors while intuitively recognizing the sense of distance from the reference point to the facility.
In addition, as shown in FIG. 3, since the facilities corresponding to all three factors for classifying the facilities are displayed, “quiet (relaxed)”, “moving (active)”, “saving”, “luxury”, “ Facilities corresponding to concepts such as “family” and “individual / friend” can be displayed at the same time, and it is possible to easily select destination candidates from a wide selection without switching screens and narrowing down to genres. it can.

  When displaying the destination candidate image, a process of displaying an image so that the origin O and the facility image do not overlap may be performed. Specifically, the main control unit 11 may perform a process of removing a facility whose travel time or distance from the reference point is less than a preset lower limit value (for example, less than 1 hour or less than 1 km) from the display target. In addition, when the scale of the coordinate system can be changed, it is preferable to change the lower limit value according to the scale so that a destination candidate image that does not overlap with the origin O can be displayed. In addition, a destination candidate image that overlaps the origin O by changing the viewpoint described later may be excluded from the display target. Such display processing may be performed by the main control unit 11 or may be performed by another processing unit.

  Further, instead of displaying the destination candidate image that overlaps the origin O, the display position may be offset according to a predetermined rule so as not to overlap the origin O. You may enable it to change a setting suitably. As a result, the origin O can be easily seen and the sense of distance to the facility can always be easily recognized.

Further, when displaying the facility images F1 to F8, the main control unit 11 enlarges and displays the image as it is located on the near side, and reduces and displays it as it is located on the far side. In FIG. 4, images F1 to F8 are enlarged and reduced according to the position on the Z axis. This makes it easier to visually and intuitively recognize the positions in the depth direction of the images F1 to F8.
More specifically, the images F1, F2, and F6 of the facility for families are displayed relatively large, and the images F3 and F7 of the facility for individuals / friends are displayed relatively small. Further, the images F4, F5, and F8 of other facilities are displayed in an intermediate size. This makes it easier for the user to intuitively recognize the correspondence between facilities and factors, and makes it easier to select destination candidates.

  In the case of the display state shown in FIG. 4, when the user selects a facility image F1 to F8 via the touch panel (step S19; selection of destination candidates), the main control unit 11 performs the selection operation. The facility corresponding to the displayed image is set as a destination (destination), and the process proceeds to a process of searching for a recommended route from the reference point to the destination (step S20). Thereby, the recommended route to the destination candidate selected by the user is automatically searched, and the route guidance process can be started quickly.

  Instead of the process of step S20, a destination candidate registration process for registering the facility corresponding to the selected and selected image in the “destination candidate of interest” may be performed. In this case, for example, the storage unit 18 stores identification information for identifying the “desired destination candidate” facility. When the display of “desired destination candidates” is instructed through a predetermined operation by the user, a list of facilities is displayed on the display unit 13 based on the identification information. Thereafter, when the user selects the destination (destination), the processing of the above step may be performed.

  On the other hand, when the user selects the two-dimensional display of the spherical coordinates (step S19; selection of the two-dimensional display), the main control unit 11 proceeds to a screen display process according to the user's instruction (step S21). In this case, the selection of one of the three coordinate axes is received from the user, and when this selection is made, two-dimensional two-dimensional display excluding the selected one axis is performed. For example, when the user performs a touch operation on an area corresponding to “individual / friend” on the coordinate axis (Z axis) corresponding to “who is going”, the main control unit 11 uses the “individual / friend” side as a viewpoint. A two-dimensional display corresponding to is performed. A display example of the destination candidate image in this case is shown in FIG.

As shown in FIG. 5, the display unit 13 has a viewpoint “individual” designated by the user in a coordinate system including a coordinate axis (X axis) corresponding to “purpose” and a coordinate axis (Y axis) corresponding to “cost”. Only the images F3 to F5, F7, and F8 visible from the “/ friend” side are displayed.
Here, the images F3 to F5, F7, and F8 are images of facilities that are “individual / friends” and “other evaluations” among the three evaluations classified by “purpose”. Processing is performed by the main control unit 11. That is, when the “individual / friend” is touch-operated by the user, the main control unit 11 extracts the facility excluding the facility for the “family” at the opposite end of the “individual / friend”, and only the image of the extracted facility. Are displayed in a predetermined reference size (corresponding to an intermediate size in FIG. 4).

As shown in FIG. 5, the displayed facility image is a position where the distance from the origin O is the travel time from the reference point (home U1) to each facility, and classifies each facility. It is displayed at a position determined by the coordinate axes (X and Y axes) of “purpose” and “cost”.
This makes it possible to select destination candidates based on the combination of the distance from the origin O and the two factors while narrowing down the destination candidates according to the user's instruction.

In FIG. 5, since the facilities corresponding to two evaluations (“individual / friend” and “other evaluation”) among the facilities classified as “going with whom” are displayed, one evaluation (“individual / Compared to the case where the facility corresponding to “friend”) is displayed, a larger number of facilities can be displayed. However, when the number of displays exceeds a preset maximum number, only facilities corresponding to one evaluation (“individual / friend”) may be extracted and displayed from the viewpoint of ensuring visibility. .
In addition, a method of displaying facilities corresponding to two evaluations (“individual / friends” and “other evaluations”) and a single evaluation (“individual / friends”) are set by a user or the like in advance. The method of extracting and displaying only the facility may be switched.

Furthermore, in the display state shown in FIG. 4, when the user touches the position corresponding to “family”, the main control unit 11 performs two-dimensional display of X and Y axes corresponding to the case where the “family” side is the viewpoint. I do. A display example of the destination candidate image in this case is shown in FIG.
As shown in FIG. 6, the viewpoint “family” pointed to by the user enters a two-dimensional coordinate system including coordinate axes (X axis) corresponding to “purpose” and coordinate axes (Y axis) corresponding to “cost”. Only visible images F1, F2, F4 to F6, F8 are displayed. Here, the images F1, F2, F4 to F6, and F8 are images of facilities that are set as “family” and “other evaluation” among the three evaluations classified by “purpose”.

The facility image displayed in FIG. 6 is a position where the distance from the origin O is the travel time from the reference point (home U1) to each facility, and the “purpose” and “ The cost is displayed at a position determined by the coordinate axes (X and Y axes).
As a result, the viewpoint can be changed and displayed according to the user's instruction, and the destination candidate can be selected based on the combination of the distance from the origin O and the two factors while selecting the destination candidates. Become.
Also in this case, when the number of displays exceeds a preset upper limit number, or according to the setting of the user or the like, only the facility corresponding to one evaluation (“family”) may be extracted and displayed. .

Furthermore, in any of the display states shown in FIGS. 4 to 6, any viewpoints (“static (relaxed)”, “moving (active)”, “saving”, “ When the user selects “luxury”, the viewpoint is changed according to the user's instruction in the same manner as described above.
Thus, the viewpoint can be freely changed and displayed, and the destination candidate can be selected based on the combination of the distance from the origin O and the desired two factors while narrowing down the destination candidates. .

  After the two-dimensional display as described above, as shown in FIG. 3, the process proceeds to step S <b> 19, and when the user selects one of the facilities images F <b> 1 to F <b> 8 via the touch panel (step S <b> 19; Selection of destination candidate), the main control unit 11 proceeds to the process of step S20. Thereby, the recommended route to the destination candidate selected by the user is automatically searched, and the route guidance process can be started quickly.

  On the other hand, when a condition change is instructed by the user in step S19, the main control unit 11 returns to the process of step S11. Thereby, the reference point can be changed, and the destination candidate image can be displayed based on the changed reference point. The above is destination candidate display processing.

As described above, in the present embodiment, as shown in FIGS. 4 to 6, the reference point selected by the user is the origin O, and the distance from the origin O corresponds to the travel time from the reference point. Since a plurality of destination candidates existing around the reference point are displayed in the coordinate system with the coordinate axes X to Z as factors for classifying the destination candidates (“purpose”, “cost”, “go to whom”), the map display The destination candidate can be displayed at a position determined by a factor for classifying the destination candidate instead of the direction viewed from the predetermined point.
This makes it possible to select a destination candidate based on a combination of a distance from the origin O and a factor. Accordingly, it is possible to intuitively recognize the sense of distance from the reference point (predetermined point) and to display destination candidates without depending on the genre (that is, the facility attribute), and it is easy to select a favorite destination candidate. Become.

The factor includes a concept of a counter electrode, and one of the coordinate axes (X to Z axes) indicates one concept (that is, the first concept) with respect to the origin O and the other with respect to the origin O. However, since the other concept (that is, the second concept opposite to the first concept) is shown, the destination candidates classified by the concept of the counter electrode can be easily displayed at the same time, and the preferred destination candidate can be easily selected. Become.
The coordinate system is a spherical coordinate system with the origin O as the center of the sphere (see FIG. 4). The spherical coordinate system is converted into an image when viewed from a predetermined viewpoint, and the viewpoint is changed. (See Fig. 5 and Fig. 6), the spherical coordinate system has more flexibility in the display position of destination candidates and corresponds to the factors than the circular coordinate system centered on the origin O. The number of coordinate axes can be increased. In addition, since the change of the viewpoint is accepted, the preferred destination candidate can be displayed in an easy-to-see manner, and two-dimensional display similar to the circular coordinate system is also possible.

  In addition, it has three coordinate axes (X to Z axes) orthogonal to each other, and a destination candidate narrowed down based on a factor of any one of the coordinate axes (any of X to Z axes) based on a user instruction, Since it is displayed in a two-dimensional coordinate system having the remaining two coordinate axes (see FIGS. 5 and 6), the destination candidates narrowed down based on the user's instructions are imaged with a sense of distance in the two-dimensional coordinate system. Can be displayed. This makes it possible to easily select a destination candidate using a combination of a distance and a factor composed of two coordinate axes as a selection criterion.

  Also, based on POI data DA (first data) that describes at least the positions of a plurality of destination candidates, the travel time from the reference point is calculated, and the calculated travel time and the facilities where these destination candidates are classified by the above factors Since the destination candidates are displayed in the spherical coordinate system based on the classification data DB (second data), known POI data can be used. Moreover, the well-known data which classified the destination candidate on various conditions can also be utilized for facility classification data DB. Therefore, it is possible to display destination candidates by using known data.

In addition, it searches for destination candidates within a preset range of travel time from the reference point, and displays the extracted destination candidates in the above coordinate system, so far away places can be excluded from destination candidates, improving visibility In addition, the amount of calculation processing can be reduced by the amount to be eliminated. The above setting range may be arbitrarily set by the user or the like.
Further, when displaying the destination candidate image, since the destination candidate whose travel time or distance from the reference point is less than the preset lower limit value is excluded from the display target, the origin O of the display coordinates is visually recognized. It is possible to easily display the sense of distance to the destination candidate.

  In the above-described embodiment, a pinch-out operation or a pinch-in operation in an arbitrary area of the user's destination candidate image is accepted, and the main control unit 11 displays an enlarged image according to the pinch-out operation, and displays a reduced image according to the pinch-in operation. Also good. Moreover, when an arbitrary facility is pinched out, other candidates having the same conditions as the facility may be additionally displayed. For example, when the image of “Yokohama Red Brick Warehouse” is pinched out, “Yokohama Landmark Tower” or the like classified as a tourist facility in the same area may be additionally displayed. This makes it possible to additionally display destination candidates that are likely to be of interest to the user.

In the above-described embodiment, the pitch of the coordinate system may be arbitrarily changed according to a user operation. For example, the pitch may be made variable in accordance with a pinch-in operation or a pinch-out operation of a portion to be changed in the two-dimensional display.
FIG. 7A shows a case where a pitch between specific scales (pitch between scales M1 and M2 in FIG. 7A) is enlarged and displayed by a pinch-in operation. By using this display, the visibility of information between the scales M1 and M2 is improved. Therefore, when selecting a destination candidate on the condition of the movement time between the scales M1 and M2, it becomes easy to select a destination candidate. Furthermore, the amount of information (for example, the number of facilities) in the enlarged display area may be increased.

FIG. 7B shows a case where the pitch of a specific area (pitch of scales M1 to M3 in the left area in FIG. 7B) is enlarged and displayed by a pinch-in operation. This display improves the visibility of the information in the left area, and makes it easier to select a destination candidate when selecting a destination candidate on the condition of the left area. Also in this case, the amount of information (for example, the number of facilities) in the enlarged area may be increased.
Further, the pitch may be automatically changed based on the current time. To give a specific example, if the present is in the afternoon, the pitch between specific scales corresponding to the time range to go out (the pitch between the scales M2 and M3 that are travel time 2h to 3h (one way)). The pitch between the scales corresponding to the near time range (pitch up to the scale M2) may be enlarged and displayed. On the other hand, if the current time is in the morning, contrary to the case of the above-mentioned afternoon, the pitch between the specific scales corresponding to the time range to go out is widened, and between the scales corresponding to the near time range The pitch (pitch up to the scale M2) may be narrowed and displayed.

Further, in each of the above-described embodiments, when a user drags (moves) an image of a destination candidate facility to the origin O, the facility moved to the origin O is set as a reference point, and based on the reference point. Re-searching and re-drawing (corresponding to step S15 shown in FIG. 3) may be performed. In this case, facilities around the facility moved to the origin O can be displayed, and further destination candidates can be examined.
As a specific example, FIG. 8A shows an example in which the image F2 of theme park A is dragged to the origin O. FIG. In FIG. 8A, shopping center image F1A, mountain image F5A, and sea image F8A are displayed as facilities that are not displayed when home U1 is set to origin O, and these are selected as destination candidates. Can do.

Further, in each of the above-described embodiments, the case where the distance from the origin O is set as the movement time from the reference point has been described. However, as shown in an example in FIG. It may be a distance from the point. In this case, in FIG. 8B, the sphere scales M1 to M3 centering on the origin O indicate the distance from the reference point. This distance may be either a linear distance or a recommended route distance.
Also, the user or the like may arbitrarily switch whether to indicate the travel time from the reference point or the distance from the reference point. Further, the moving time or moving distance may be switched to a one-way / reciprocal display. That is, in the above embodiment, the travel time or travel distance required for one way from the reference point to the facility is displayed, but the travel time or travel distance required for a round trip between the reference point and the facility is displayed according to the user's operation. You may display.

  In the above-described embodiment, the case where the main control unit 11 of the navigation device 1 performs the destination candidate display process has been described. However, a server (for example, the service providing server 31) on the communication network performs the destination candidate display process. May be. In this case, the service providing server 31 may input a user instruction from the navigation device 1, generate a destination candidate display image, and display the destination candidate display image on the display unit 13 of the navigation device 1. According to this configuration, in order to perform various computations for destination candidate display processing using a server that generally has high processing capacity and storage capacity, the computation processing is shortened and appropriate information is selected from a large amount of the latest data. It becomes easy to do.

Further, in the above-described embodiment, the case where the factors for classifying the destination candidates are set to the three factors consisting of “purpose”, “cost”, and “with whom” is described, but the types and number of factors are limited to this. However, various factors may be applied.
Moreover, although the above-mentioned embodiment demonstrated the case where the control program for performing a destination candidate display process was previously memorize | stored in the navigation apparatus 1, it is not restricted to this, This control program is magnetic recording medium, optical It may be stored in a computer-readable recording medium such as a recording medium or a semiconductor recording medium, and the computer may read and execute this control program from the recording medium. The control program may be downloaded from a distribution server or the like via a communication network (electric communication line).
Moreover, although the case where this invention was applied to the navigation apparatus 1 was demonstrated in the above-mentioned embodiment, you may apply apparatuses other than a navigation apparatus. In short, the present invention can be widely applied to various information processing apparatuses that display destination candidates.
