Good. Further, the change display unit 102n may further cause the display unit 114 to display a map data display screen based on the navigation information. For example, the change display unit 102n further receives the navigation received by the navigation information receiving unit 102k on the map data received by the navigation information receiving unit 102k based on the display priority determined by the display priority determining unit 102m. A display screen (search result display) on which information is superimposed may be displayed on the display unit 114. Specifically, the change display unit 102n further includes, on the map data of the map including the guidance route based on the guidance route data included in the navigation information, based on the display priority determined by the display priority determination unit 102m. A display screen on which the guide route data included in the navigation information is superimposed may be displayed on the display unit 114. Further, the change display unit 102n further converts the navigation information into the map data of the map including the location of the POI based on the POI information included in the navigation information based on the display priority determined by the display priority determination unit 102m. A display screen on which the included POI information is superimposed may be displayed on the display unit 114. Further, the change display unit 102n may further cause the display unit 114 to display a display screen based on the current position information of the user of the terminal device 100 acquired by the current position information acquisition unit 102a. Further, the change display unit 102n further causes the display unit 114 to re-display the display screen based on the navigation information received by the navigation information receiving unit 102k based on the display priority determined by the display priority determination unit 102m. Also good.

  The route guidance unit 102p is route guidance means for executing route guidance by outputting navigation information via an output unit. Here, the route guidance unit 102p may perform route guidance by causing the display unit 114 to display a display screen based on the navigation information. For example, the route guide unit 102p may cause the display unit 114 to display a display screen based at least on the guide route data included in the navigation information. Further, the route guide unit 102p may further output the current position information of the user of the terminal device 100 via the output unit. For example, the route guide unit 102p may cause the display unit 114 to display a display screen in which the guide route data and the current position information of the user of the terminal device 100 are superimposed on the map data. The route guidance unit 102p may output voice guidance data based on the navigation information via the voice output unit 118. For example, the route guidance unit 102p may output the voice guidance data associated with the traveling direction or the like at a branch point on the guidance route based on the guidance route data via the voice output unit 118.

  Above, description of an example of a structure of the search system in 1st Embodiment is finished.

[Search system processing]
Next, an example of processing of the search system according to the first embodiment configured as described above will be described in detail with reference to FIGS. 2 to 9 below. FIG. 2 is a flowchart illustrating an example of processing of the search system according to the first embodiment.

  As shown in FIG. 2, first, the display priority item setting unit 102b of the terminal device 100, among the items included in the navigation information, when the user implements the application that implements the present invention via the input unit 116, Then, an item that is preset in the application as an initial setting display priority item (default display priority item) and is used to determine the priority order when displaying navigation information is set as a display priority item (step SA-1). Here, the display priority item setting unit 102b may set an item specified by the user via the input unit 116 among the items included in the navigation information as the display priority item. In addition, the display priority item setting unit 102b may set the display priority item at the end of the previous application as the display priority item among the items included in the navigation information.

  Then, the input screen display unit 102c of the terminal device 100 displays a display screen for inputting the priority, in which the priority of the plurality of display priority items set by the display priority item setting unit 102b is displayed as a graph. Is displayed on the unit 114 (step SA-2). Here, the graph may be a polygonal radar chart corresponding to the number of display priority items. The graph may be a bar graph. In addition, the graph may include a line segment that links the priorities of the display priority items whose arrangement is adjacent in the graph.

  Here, an example of the display screen in the present embodiment will be described with reference to FIGS. 3 to 5. 3 and 5 are diagrams illustrating an example of a display screen in the present embodiment. FIG. 4 is a diagram showing an example of a bar graph display of the priority of the display priority item in the present embodiment.

  FIG. 3 is an example of a display screen for searching for various categories (for example, ramen) based on the priority of the display priority item. As shown in FIG. 3, the input screen display unit 102c has an input screen area in which the priority of the three display priority items (reputation, low price, and proximity) set by the display priority item setting unit 102b is set as a radar chart. A display screen for inputting the priority displayed on AR2 is displayed on display 114. Here, the radar chart may be a graph in which the user can operate the value with a finger.

  Here, as shown in FIG. 3, the radar chart displayed in the input screen area AR2 includes input means for priority points (correction values) corresponding to the priorities of a plurality of display priority items. The priority points (PA, PB, and PC) of the POI display priority items (ITEM A: reputation, ITEM B: low price, and ITEM C: proximity) set in the The value of the priority point can be input (changed) by being moved through 116. Here, the value of the priority point may be changed to the priority of the display priority item by the correction value calculation unit 102i. Further, “closeness” as the display priority item ITEM C means the center of the map displayed in the input screen area AR4, the distance from the point designated by the user or the length of the arrival time, the destination inputted in advance. It may be a distance from a polyline such as a guide route to the destination, or a distance or required time of a guide route via a POI to a destination inputted in advance. In addition, when the line segment (LA, LB, and LC) that links the priority points of the display priority items that are adjacent to each other in the radar chart is linked via the input unit 116, the linkage changing unit 102g. Can move the priority points to be connected at the same time, and can change the ratio of multiple display priority items by the same ratio or amount (for example, by pushing or pulling, Change the position of the priority point). Here, the line segment to be linked may change the display priority item close to the designated position on the line segment. Thereby, since only one line segment can be designated and the ratio of the plurality of display priority items can be changed by operation, the priority points of the plurality of display priority items can be easily changed. PA, PB, PC, LA, LB, and / or LC values can be changed by the user dragging and dropping PA, PB, PC, LA, LB, and / or LC via the input unit 116. You may be able to do it. Accordingly, the user can intuitively control PA, PB, PC, LA, LB, and / or LC displayed on the display unit 114 via the input unit 116, which is convenient for the user. Improves.

  Further, the center button (CB) in the radar chart, when the user presses the center button via the input unit 116 (for example, click or long press), the priority point is set to the default priority (for example, each It is possible to return to a position corresponding to a value (equal value, etc.) with equal priority. Thereby, a plurality of display priority items can be easily changed to the original values. In addition, when a predetermined fixing operation for priority points is continuously input by the user via the input unit 116, and priority points of other display priority items are moved by the user via the input unit 116, continuous The priority point of the item that is fixedly operated (pressed continuously) can be prevented from changing. Thereby, other display priority items can be changed without changing some display priority items. Further, when a fixing operation such as double-clicking a certain display priority item is input by the user via the input unit 116, the priority point of the display priority item can be fixed. Thereby, other display priority items can be changed without changing some display priority items. Here, FIG. 3 illustrates an example of POI search as a display priority item, but different display priority items may be selected depending on the type of search. For example, when searching for a guidance route for the same start point and destination point, time, distance, fuel consumption, paid fee, and the like may be set as display priority items. By displaying the route search result with the designated priority on the display unit 114, the user can easily search for the desired route, and the convenience is improved. Further, when searching for reviews, the hit rate of the designated character string, the popularity of the review target or the word-of-mouth writer, the elapsed time since the last update, and the like may be set as display priority items. As a result, the user can easily search for the desired word of mouth, and the convenience for the user is improved.

  Further, as shown in FIG. 3, the input screen area AR3 includes items (ITEM D) included in navigation information other than the display priority items (ITEM A, ITEM B, and ITEM C) displayed in the input screen area AR2. : Ranking, ITEM F: Rapid rise, and ITEM G: Recommendation) are displayed. Here, when an item in the input screen area AR3 is flicked or dragged and dropped into the input screen area AR2, the item is added as a display priority item in the input screen area AR2. When the display priority item in the input screen area AR2 is flicked or dragged and dropped into the input screen area AR3, the display priority item in the input screen area AR2 is reduced and added as an item in the input screen area AR3. Thereby, in this embodiment, the display priority item can change the number of items dynamically. Therefore, in FIG. 3, the radar chart displayed in the input screen area AR2 is displayed by flicking or dragging and dropping ITEM D, ITEM F, and ITEM G in the input screen area AR3 to the input screen area AR2. It can be expanded into a square. Here, the items displayed in the input screen area AR3 may be changed by the user (for example, other item candidates are presented by clicking).

  Also, as shown in FIG. 4, the input screen display unit 102c is an input screen in which the priority of the three display priority items (reputation, low price, and proximity) set by the display priority item setting unit 102b is a bar graph. The display screen for inputting the priority displayed in the area AR2 can be displayed on the display unit 114.

  As shown in FIG. 3, the input screen area AR1 includes a text box for inputting a search condition, a search button for starting a search, a condition change button for specifying a search (condition change), and the like. Has been. Here, when the search button is pressed, transmission processing of the search condition to the navigation server 200 is started. In addition, when the condition change button is pressed, if a search genre or the like is specified on a different screen to be displayed, the specified one is input in the search condition input area. Further, in the present embodiment, when the search button is pressed, the priority determination process for the display priority item corresponding to each priority point by the priority determination unit 102h based on the positions of the priority points PA, PB, and PC, and The search condition acquisition processing by the control unit 102 may be started (for example, search start processing of POI included in the area corresponding to the genre and displayed in the map on the input screen area AR4). Even when the search button is not pressed, the transmission process of the search condition to the navigation server 200 may be started. As an example, there is a time when the search is started or a search condition is changed.

  In addition, as display priority items, not only items consisting of quantitative data for which priority can be specified, but also items consisting of qualitative data for narrowing down search conditions may be designated. As shown in FIG. 3, in the input screen area AR3, not only items consisting of quantitative data for which priority can be specified, but also qualitative data (qualitative conditions) for narrowing down search conditions not linked to the item. ) (ITEM E: display start index) for designating. Examples of items consisting of qualitative data include taste conditions (eg, soy sauce, salt, miso, or tonkotsu) provided by POI, whether it is a specialty store or a dealer, etc. And the degree of matching with the search condition (for example, matching is essential or matching if possible). The priority determination unit 102h does not change the priority value even if the value of the other item fluctuates for the item composed of qualitative data.

  FIG. 5 is an example of a display screen for searching for various categories (for example, ramen etc.) based on the priority of the display priority item. The display priority item on the display screen shown in FIG. In the display screen for entering the priority, the priority of the three display priority items (reputation, cigarette, and proximity) is displayed in the input screen area AR2 as a radar chart. is there.

  Here, as shown in FIG. 5, the radar chart displayed in the input screen area AR2 includes priority point input means corresponding to the priorities of a plurality of display priority items, and three are set in the radar chart. Display priority items (ITEM A: Reputation, ITEM B: Cigarettes, and ITEM C: Proximity) of priority points (PA, PB, and PC) moved by the user via the input unit 116 By doing so, the value of the priority point can be input (changed). Here, “tobacco”, which is the display priority item ITEM B, indicates the degree of smoke separation in a facility (for example, a store), and in this embodiment, the closer PB is to the center (CB) of the radar chart. The “all smoking cessation” facility is shown, and the “all smoking” facility becomes closer to the top of the radar chart. Further, “low price” which is the display priority item in FIG. 3 is displayed as another item ITEM F in the input screen area AR3 in FIG. In FIG. 5, items other than the display priority item ITEM B displayed in the input screen area AR2 and items related to the other items ITEM F displayed in the input screen area AR3 are the same as those in FIG. Is omitted.

  Returning to FIG. 2, the priority determination unit 102 h of the terminal device 100 inputs the input display priority based on the priority of the display priority item input by the user using the display unit 114 via the input unit 116. Priorities of display priority items other than the item priority are determined (step SA-3). Here, when the priority of one display priority item is changed via the input unit 116, the priority determination unit 102h displays other display other than the priority of the changed display priority item based on the change. The priority of the priority item may be determined. In addition, when the priorities of the plurality of display priority items are changed together via the input unit 116, the priority determination unit 102h has a priority other than the priority of the display priority item changed based on the change. The priority of the display priority item may be determined.

  Further, the priority determination unit 102h, when a designation operation for an item is input by the user via the input unit 116, based on the change of the display priority item by the item change unit 102f, other than the changed display priority item The priority of other display priority items may be determined. In addition, the priority determination unit 102h receives a movement operation for a line segment that links the priorities of display priority items whose arrangements are adjacent in the graph by the user via the input unit 116, and the link change unit 102g inputs the line segment. When the priorities of the display priority items connected in the above are changed in conjunction, the priorities of other display priority items other than the changed display priority item may be determined. Further, the priority determination unit 102h further inputs a predetermined fixing operation for the priority of the display priority item (for example, double click) via the input unit 116, and the fixing unit 102d sets the display priority item. When the fixation that does not change the priority is performed, the priority of the display priority item other than the priority of the fixed display priority item may be determined. In addition, the priority determination unit 102h receives the initializing operation when a predetermined initialization operation is input via the input unit 116 and the priority of each display priority item is changed to the default priority by the initialization unit 102e. The priority of display priority items other than the priority of the converted display priority items may be determined.

  Here, an example of changing the priority of a plurality of display priority items in the present embodiment will be described with reference to FIG. FIG. 6 is a diagram illustrating an example of display change of the radar chart in the present embodiment.

  In FIG. 6, the priority of each display priority item is determined according to the positions of the priority points PA, PB, and PC, and the sum of the priorities corresponding to the priority points PA, PB, and PC is 1. Is set. As shown in FIG. 6, when the priority point PA moves according to the user's operation, the priority determination unit 102h changes the priority points (priority points PB and PC) of other display priority items based on the priority point PA. Specifically, as shown in the upper left diagram of FIG. 6, from the state in which the priority corresponding to the priority point of each display priority item is 0.33, as shown in the upper right diagram of FIG. When the priority point PA of the display priority item “” is changed to a position corresponding to the priority 0.5, the priority determination unit 102 h displays the “priority” display priority item based on the position change of the priority point PA. The priority point PB is changed to a position corresponding to the priority 0.25, and the priority point PC of the “priority” display priority item is changed to a position corresponding to the priority 0.25. Thus, since the priority points of other display priority items can be changed as the position of one priority point is changed, the priority points of a plurality of display priority items can be easily changed.

  Returning to FIG. 2, the change display unit 102 n of the terminal device 100 displays the priority of the display priority item input by the user via the input unit 116 in step SA-3 and the priority in step SA-3. Based on the priority of the display priority item determined by the determination unit 102h, a display screen in which the display of the graph is changed is displayed on the display unit 114 (step SA-4). Here, the change display unit 102n displays a display screen in which the graph display is changed based on the correction value calculated by the correction value calculation unit 102i, or the priority or the correction value mutually converted by the correction value calculation unit 102i. You may display on the display part 114. FIG.

  Here, an example of a display change of the radar chart in the present embodiment will be described with reference to FIG. As shown in FIG. 6, the change display unit 102n changes the positions of the priority points PA, PB, and PC based on the priority determined by the priority determination unit 102h. Specifically, when the priority point PA is moved upward from the state in which the priority points of the respective display priority items are uniform as shown in the upper left diagram of FIG. 6, the priority point PA corresponds to the priority point PA as shown in the upper right diagram of FIG. The priority corresponding to the priority points PB and PC decreases (for example, a decrease due to trade-off interlocking, a decrease according to a dynamic law, etc.). When the priority point PA is moved to the top (ie, 1), the priority points PB and PC become 0 as shown in the lower right diagram of FIG. Further, when the priority point PA is pushed down from the state shown in the upper left diagram of FIG. 6, the priority corresponding to the priority point PA decreases and the priority corresponding to the priority points PB and PC increases as shown in the lower left diagram of FIG. (For example, allocate the increased amount evenly.)

  An example of changing the priority point display according to this embodiment will be described with reference to FIGS. 7 and 8. 7 and 8 are graphs showing an example of priority point display change in the present embodiment.

  In this embodiment, the priority point of the display priority item to be displayed and the priority corresponding to the priority point are normalized from 0 to 1, and the sum of the priority points corresponding to the priority points of all display priority items is 1. When the priority points are reduced, the reduced amount is equally allocated to other display priority items, and when a certain priority point is increased, the increased amount is reduced from the other display priority items. The change display unit 102n displays the radar chart value (priority point) when the priority of all display priority items is equal because the user is difficult to operate if the priority value is assigned to the radar chart as it is and displayed. Conversion is performed by the correction value calculation unit 102i so that the position (set value) becomes 1/2 (the number of display priority items is 3 or more). Thereby, the display of the radar chart is adjusted so that the equal value of each display priority item is exactly half.

（ここで、対数の底は任意の実数であってもよい。）

Specifically, when the number of display priority items is 10 and the priority of each display priority item is equal, the priority of each display priority item is 0.1. Therefore, as shown in FIG. 7, the correction value calculation unit 102i sets the priority 0.1 to the priority point 0.0 so that the display position of each display priority item in the radar chart becomes the median value of 0.5. The correction is made to be 5. When the number of display priority items is 3 and the priority of each display priority item is equal, the priority of each display priority item is 0.333 (that is, 1/3). Therefore, as shown in FIG. 8, the correction value calculation unit 102i has a priority of 0.333 as the priority point 0. The correction is made to be 5. For example, the priority point (y) set in these radar charts can be obtained by the following Equation 1 or Equation 2, where the number of display priority items is n and the priority is x.

(Here, the base of the logarithm may be any real number.)

  Returning to FIG. 2, the control unit 102 of the terminal device 100 acquires search conditions for navigation information input by the user via the input unit 116 (step SA-5). The search condition may be a condition for specifying the POI information. For example, the search condition may be information such as the name of the POI, the location, the purpose of use, the handling product including the provided food, and the genre. Further, the search condition may be a route search condition for route search, and may be information such as a departure place, a destination, a waypoint, a departure time, an arrival time, and a route time, for example. Here, the departure time may be the current time. The departure place may be the current position of the user of the terminal device 100. Further, the control unit 102 may further acquire the current position information of the user of the terminal device 100 acquired by the current position information acquisition unit 102a as a search condition. Further, the control unit 102 may further acquire the position information of the map data displayed on the display unit 114 as a search condition.

  And the search condition transmission part 102j of the terminal device 100 transmits the search condition of navigation information to the navigation server 200 (step SA-6).

  Then, the search condition receiving unit 202a of the navigation server 200 receives the search condition for navigation information transmitted from the terminal device 100 (step SA-7).

  Then, the navigation information acquisition unit 202c of the navigation server 200 extracts and acquires navigation information including POI information that satisfies the search condition received by the search condition reception unit 202a from the navigation information database 206b (step SA-8). Here, the navigation information acquisition unit 202c guides from the departure point to the destination that satisfy the route search condition generated by the guidance route search unit 202b and stored in the navigation information database 206b and received by the search condition reception unit 202a. The route guidance route data may be obtained by extracting from the navigation information database 206b.

  Then, the navigation information transmitting unit 202d of the navigation server 200 transmits at least the navigation information acquired by the navigation information acquiring unit 202c to the terminal device 100 (step SA-9). Here, the navigation information transmitting unit 202d may further transmit the map data stored in the map database 206c of the map including the location of the POI based on the POI information included in the navigation information to the terminal device 100. Further, the navigation information transmitting unit 202d may transmit map data stored in the map database 206c of the map including the guide route based on the guide route data included in the navigation information to the terminal device 100. Here, the navigation information transmitting unit 202d may generate map data with the navigation information (for example, POI information) acquired by the navigation information acquiring unit 202c and transmit the map data to the terminal device 100.

  And the navigation information receiving part 102k of the terminal device 100 receives the navigation information transmitted from the navigation server 200, and stores the received navigation information in the navigation information file 106a (step SA-10). Here, when the existing navigation information is stored in the navigation information file 106a, the navigation information receiving unit 102k may store the newly set navigation information by overwriting the existing navigation information. Further, the navigation information receiving unit 102k may further receive map data of a map including the location of the POI based on the POI information included in the navigation information transmitted from the navigation server 200. Further, the navigation information receiving unit 102k may further receive map data of a map including a guide route based on the guide route data included in the navigation information transmitted from the navigation server 200. The navigation information receiving unit 102k may store the received map data in the navigation information file 106a.

  The display priority determining unit 102m of the terminal device 100 prioritizes the navigation information received by the navigation information receiving unit 102k and the display priority item input by the user via the input unit 116 in step SA-3. The display priority (score) of navigation information is determined (calculated) based on the priority and the priority of the display priority item determined by the priority determination unit 102h in step SA-3 (step SA-11). .

  Here, an example of display priority (score) calculation processing in the present embodiment will be described with reference to FIG. FIG. 9 is a diagram illustrating an example of display priority calculation processing according to the present embodiment.

  As shown in FIG. 9, first, the display priority determination unit 102m calculates a value 12 obtained by normalizing the value of the item set as the display priority item included in the navigation information 10. As a normalization method, for example, the value may be converted so that the lower limit value of the item can be 0 and the upper limit value is 1. In this case, for example, if the value that can be taken by the evaluation item is a value from 1 to 5, evaluation 1 is converted to 0 and evaluation 5 is converted to 1. Further, as an example of different normalization, values may be converted so that the upper limit value of the item can be 0 and the lower limit value is 1. For example, in the case of the item “low price”, since the value after normalization should be larger when the price is lower than when the price is higher, the highest value is converted to 0 and the lowest price is converted to 1. As an example of different normalization, values may be converted so that the average of the corresponding items of all records included in the navigation information 10 is 0 and the variance is 1. In this case, for example, when all the records included in the navigation information 10 are three and the evaluation values are 1, 4, and 4, respectively, the average of all the records is 3, and the sample variance is 2. Is converted into (1-3) / √2 = −√2, and evaluation 4 is converted into (4-3) / √2 = √2 / 2. For example, the display priority determination unit 102m normalizes the BB noodle evaluation 3 included in the navigation information 10 by converting the values so that the lower limit value of the item value is 0 and the upper limit value is 1. Obtain 0.6 as the normalized value 12. Then, the display priority determination unit 102m includes the priority of the display priority item input by the user via the input unit 116 and the priority value 11 of the display priority item determined by the priority determination unit 102h. Then, the values multiplied by the normalized value 12 are summed, and the display priority (total score) 13 is calculated. For example, the display priority determination unit 102m has normalized each of the priority values of 0.333 and the display priority items of “reputation”, “proximity”, and “low price” of BB noodles. The values obtained by multiplying the values 12, 0.6, 0.7, and 0.8, are summed (= 0.333 * 0.6 + 0.333 * 0.7 + 0.333 * 0.8), and display priority As the (total score) 13, 0.70 is calculated. Furthermore, the display priority determination unit 102m can sort the records using the calculated total score 13.

  Returning to FIG. 2, the change display unit 102n of the terminal device 100 determines the POI to be displayed on the display unit 114 based on the display priority determined by the display priority determination unit 102m in Step SA-11, and navigates. A part of the POI information included in the navigation information received by the navigation information receiving unit 102k or the map data including the location of the POI based on the POI information included in the navigation information received by the information receiving unit 102k A display screen (search result display) in which all of them are superimposed is displayed on the display unit 114 (step SA-12). Here, the change display unit 102n is based on the guide route data included in the navigation information received by the navigation information receiving unit 102k based on the display priority determined by the display priority determining unit 102m in step SA-11. A display screen in which the guide route data included in the navigation information received by the navigation information receiving unit 102k is superimposed on the map data of the map including the guide route may be displayed on the display unit 114. Further, the change display unit 102n may further cause the display unit 114 to display a display screen based on the current position information of the user of the terminal device 100 acquired by the current position information acquisition unit 102a.

  Here, an example of the search result display in the present embodiment will be described with reference to FIG. As shown in FIG. 3, part or all of the POI search results are displayed in the input screen area AR4. Here, the change display unit 102n changes the degree of enhancement of the POI display according to the display priority, and displays the POI information in the input screen area AR4. Specifically, in the change display unit 102n, balloons of BB noodles, ramen EE, AA eaves, and ramen CC having a high display priority (overall score) are displayed as highlighted. Here, the change display unit 102n may preferentially display the POI information having a high total score on the map data, set a color for each display priority item, and color the POI for display. May be. In addition, depending on the total score, the point display (for example, stars) of the POI information may be represented by a change in size, presence / absence of a balloon, color, and the like. Further, the order from the top when the POIs are rearranged in the descending order of the total score may be displayed. Further, the display method on the display unit 114 may be changed according to the order from the top when the POIs are rearranged in the descending order of the total score.

Here, the priority determination unit 402h further displays the changed display based on the change of the display priority item by the item changing unit 402f when the designation operation for the item is input by the user via the input unit 416. Priorities of display priority items other than the priority items may be determined.

  Then, the change display unit 402n displays the priority of the display priority item acquired by the control unit 402 in step SC-8 and the priority of the display priority item determined by the priority determination unit 402h in step SC-9. Based on the degree, a display screen in which the display of the graph is changed is displayed on the display unit 414 (step SC-10). Here, the change display unit 402n displays a display screen in which the graph display is changed based on the correction value calculated by the correction value calculation unit 402i, or the priority or the correction value mutually converted by the correction value calculation unit 402i. It may be displayed on the display unit 414.

  Then, the display priority determination unit 402m displays the navigation information acquired by the navigation information acquisition unit 402k, the priority of the display priority item acquired by the control unit 402 in step SC-8, and the step SC-9. The display priority of the navigation information is determined based on the priority of the display priority item determined by the priority determination unit 402h (step SC-11).

  Then, the change display unit 402n determines the POI to be displayed on the display unit 414 based on the display priority determined by the display priority determination unit 402m in step SC-11, and is stored in the map database 406c. A display screen in which part or all of the POI information included in the navigation information acquired by the navigation information acquiring unit 402k is superimposed on the map data of the map including the POI location based on the POI information included in the navigation information (search (Result display) is displayed again on the display unit 414 (step SC-12). Here, based on the display priority determined by the display priority determination unit 402m in Step SC-11, the change display unit 402n guides based on the guide route data included in the navigation information stored in the map database 406c. A display screen in which the guide route data included in the navigation information acquired by the navigation information acquisition unit 402k is superimposed on the map data of the map including the route may be displayed again on the display unit 414. Further, the change display unit 402n may further cause the display unit 414 to display a display screen based on the current location information of the user of the search device 400 acquired by the current location information acquisition unit 402a.

  Then, the control unit 402 determines whether or not a predetermined end process (for example, power OFF and application end process) is detected (step SC-13).

  If it is determined at step SC-13 that the predetermined end process is not detected (step SC-13: No), the controller 402 shifts the process to step SC-8.

  On the other hand, when it is determined that the predetermined end process is detected in step SC-13 (step SC-13: Yes), control unit 402 ends the process.

  Above, description of an example of the process of the search device 400 in 3rd Embodiment is finished.
