  Also, the POI data with impression information can be registered in the navigation device 11 without using the POI data provided by the information providing center. For example, based on the contents described in a print medium such as a newspaper, magazine, brochure, etc., POI data related to a desired POI is selected, impression information is added to the selected POI data, and the input unit of the navigation device 11 is operated. Thus, it can be stored in the data section 12 as registered POI data with impression information.

  Further, in the initial state of the navigation device 11, POI data related to a desired POI is selected from the POI data stored in advance in the data section 12, impression information is added to the selected POI data, and the registered POI with impression information is added. Data can be stored again in the data portion 12 as data. That is, the POI data stored in the data section 12 can be updated as registered POI data with impression information by adding impression information. Furthermore, the registered POI data with impression information stored in the data section 12 can be updated by changing the impression information.

  And the user 15 can search by impression information, when searching for POI. In this case, the user 15 operates the input unit of the navigation device 11 and inputs impression information for search. The impression information for search is an ambiguous and sensory index similar to the impression information added to the POI data. As impression information for search, only one piece of impression information from a single viewpoint can be input, or a plurality of pieces of impression information from different viewpoints can be input. When the impression information for search is input, the search processing unit 13 of the navigation device 11 executes an impression information reception process, and subsequently executes a search process based on the impression information. Then, a search result based on the impression information is output, and POI data matching the impression information input by the user 15 is displayed on the display unit. Thereby, the user 15 can search for POI from an ambiguous and sensory viewpoint.

  In the present embodiment, a POI search system as a point search system includes a point data storage unit that stores point data, an impression information input unit that inputs impression information indicating an impression of the point, and impression information from the viewpoint of functions. Impression information registration unit for adding impression information input by the input unit to the point data and registering it in the point data storage unit, and point data with impression information registered in the point data storage unit are input by the impression information input unit A point search unit for searching by impression information. In this case, POI data corresponds to the point data, and the data unit 12 of the navigation device 11 corresponds to the point data storage unit. The impression information input unit corresponds to the input unit and the display unit of the navigation device 11 and the information acquisition device 14. Furthermore, the navigation device 11 and the information acquisition device 14 correspond to the impression information registration unit. Further, the search processing unit 13 of the navigation device 11 corresponds to the POI search unit.

  Next, operations of the navigation device 11 and the information acquisition device 14 configured as described above will be described. First, an operation for registering POI data with impression information will be described.

  FIG. 1 is a diagram showing a screen for adding impression information to POI data in the first embodiment of the present invention, and FIG. 3 shows an operation for registering POI data with impression information in the first embodiment of the present invention. It is a flowchart.

  First, the user 15 operates the information acquisition device 14 to perform a registered POI input operation. Then, the information acquisition device 14 is communicably connected to the information providing center via the network, and the POI data provided by the information providing center is displayed on the information acquisition device 14 as shown in FIG. Displayed in the section. In FIG. 1A, reference numeral 21 denotes a POI display screen. In the POI display screen 21, a picture 22 showing the state of the POI, a POI information column 23 showing detailed information of the POI, and the POI are registered. A registration button 24 as a registration selection means is included. The registration button 24 is operated when the user 15 places a pointer, a cursor or the like or touches it with a finger or the like. FIG. 1A shows an example in which the POI is a restaurant.

  When the user 15 operates the registration button 24 to select the POI displayed on the POI display screen 21, the impression information menu is displayed as shown in FIG. In FIG. 1B, 31 is an impression information input screen, and the user 15 inputs impression information through the impression information input screen 31. Here, the impression information input screen 31 includes an impression keyword field 32 indicating an impression keyword, a slide bar 33 and a slide guide 34 as impression information input means for inputting impression information about the selected impression keyword, an impression, A completion button 36 as a completion selection means for completing the information input operation and a cancel button 37 as a cancellation selection means for canceling the impression information input operation are included. FIG. 1B shows an example where the restaurant shown in FIG. 1A is selected.

  The impression keyword shown in the impression keyword column 32 is a word indicating a viewpoint about the impression of the POI, and can be selected by the user 15 by placing a pointer, a cursor or the like or touching with a finger or the like. It has become. In the example shown in FIG. 1B, the “price” positioned at the top of the impression keyword column 32 is surrounded by a frame to indicate that it has been selected. The impression keywords shown in the impression keyword column 32 are preferably set in advance for each type of POI. Thereby, the user 15 can give impression information from an appropriate viewpoint according to the type of POI.

  When an impression keyword is selected, a slide bar 33 and a slide guide 34 are displayed to input impression information from the viewpoint indicated by the impression keyword. Here, both ends of the slide bar 33 are given words (words) indicating the impressions of both extremes in the above viewpoint, and the position of the slide guide 34 on the slide bar 33 between the words indicating the impressions of both extremes. Thus, the impression of the POI of the user 15 in the above viewpoint is shown. The slide guide 34 can be moved left and right on the slide bar 33 as indicated by an arrow 35 when the user 15 places a pointer, cursor, etc. or touches it with a finger or the like. it can.

  In the example shown in FIG. 1B, the slide bar 33 and the slide guide 34 positioned at the top correspond to the selected impression keyword “price”. For this reason, the words “low” and “high” are given to both ends of the slide bar 33, which are words indicating the extreme impressions of “price”. In this case, since the slide bar 33 is in a position close to “Looks cheap”, it can be seen that the user 15 has an impression that the price is low with respect to the restaurant shown in FIG.

  Further, the slide bar 33 and the slide guide 34 positioned second from the top correspond to the impression keyword “status”. Therefore, both ends of the slide bar 33 are given “wild” and “sophisticated” which are words indicating the extreme impression of “status”. In this case, since the slide bar 33 is in a position close to “elegant”, it can be seen that the user 15 has an impression that it is elegant with respect to the restaurant shown in FIG.

  Furthermore, the slide bar 33 and the slide guide 34 located third from the top correspond to the impression keyword “accompanied person”. Therefore, both ends of the slide bar 33 are given “family” and “couple” which are words indicating the extreme impressions of “accompanied persons”. In this case, since the slide bar 33 is located at a position close to the middle between the “family” and the “couple”, the user 15 is in the middle of the family orientation and the couple orientation with respect to the restaurant shown in FIG. You can see that it has an impression.

  Furthermore, the slide bar 33 and the slide guide 34 positioned fourth from the top correspond to the impression keyword “volume”. Therefore, “light” and “heavy”, which are words indicating both extreme impressions of “volume”, are given to both ends of the slide bar 33. In this case, since the slide bar 33 is slightly close to “light”, the user 15 has an impression that the amount of meal is slightly less than the restaurant shown in FIG. I understand.

  Note that the example shown in FIG. 1B is an example in which four impression keywords are selected, but the number of impression keywords to be selected may be singular or plural. Any number. The impression information input screen 31 displays a slide bar 33 and a slide guide 34 corresponding to each selected impression keyword. If the number of impression keywords selected is large and all of the corresponding slide bar 33 and slide guide 34 cannot be displayed on one screen, the screen can be displayed in a scrollable manner.

  When the input of impression information is completed, the user 15 selects the completion button 36 and inputs that the input of impression information has been completed. When canceling the input item, the cancel button 37 is selected. The completion button 36 and the cancel button 37 are operated when the user 15 places a pointer, a cursor or the like or touches it with a finger or the like.

  When the input of impression information is completed, the user 15 operates the information acquisition device 14 and transfers the POI data with the impression information to the navigation device 11 as POI data with impression information. Then, the navigation device 11 registers the transferred POI data with impression information and stores it in the data section 12 as registered POI data with impression information. That is, the registered POI and impression information are recorded in combination. Thereby, the process of registering the POI data with impression information is completed.

Next, a flowchart will be described.
Step S1: A registered POI input operation is performed.
Step S2 The impression information menu is displayed.
Step S3 Impression information is input.
Step S4: The registered POI and impression information are recorded in combination, and the process ends.

  Next, an operation for searching for POI based on impression information will be described.

  FIG. 4 is a diagram showing a screen for searching for a POI based on impression information according to the first embodiment of the present invention, and FIG. 5 is a flowchart showing an operation for searching for a POI according to the first embodiment of the present invention.

  First, the navigation device 11 is operated to activate the registered POI search function and select a search based on impression information. That is, the search processing unit 13 is activated, a screen for starting the search for POI data stored in the data unit 12 is displayed on the display unit, and the search based on impression information is selected on the screen. Here, a case where search for a restaurant is selected as the POI will be described.

  Subsequently, the impression information menu is displayed on the display unit of the navigation device 11 as shown in FIG. In FIG. 4A, reference numeral 41 denotes an impression information input screen, which is a screen on which the user 15 inputs impression information for searching. In practice, the impression information shown in FIG. The screen has almost the same screen configuration as the input screen 31, and includes an impression keyword field 32 indicating an impression keyword, a slide bar 33 as an impression information input means for inputting impression information about the selected impression keyword, and A slide guide 34 is included. FIG. 4A shows an example in which a restaurant is selected as the POI.

  Then, the user 15 inputs impression information on the impression information input screen 41. In this case, a desired impression keyword is selected from the impression keywords shown in the impression keyword column 32, and impression information is input from the viewpoint indicated by the impression keyword. FIG. 4A shows a case where “price”, “status”, “accompanied person”, and “volume” are selected as impression keywords as in the case of the operation for registering the POI data with impression information described above. Is shown. Then, from the slide bar 33 and the slide guide 34 corresponding to each impression keyword, the impression information that the price is inexpensive, elegant, intermediate between the family and the couple, and the amount of meal is slightly less is used as the search condition. You can see that it was entered as.

  The example shown in FIG. 4A is an example in which four impression keywords are selected, but the number of impression keywords to be selected may be singular or plural. Any number. The impression information input screen 41 displays a slide bar 33 and a slide guide 34 corresponding to each selected impression keyword. If the number of impression keywords selected is large and all of the corresponding slide bar 33 and slide guide 34 cannot be displayed on one screen, the screen can be displayed in a scrollable manner.

  When the input of the impression information is completed, the POI information that matches the input impression information is displayed, and the condition approximate POI list 42 is displayed as shown in FIG. 4B. The condition approximate POI list 42 is a list of restaurants as POIs to which impression information having values close to the values set by the slide bar 33 and the slide guide 34 are listed in order. The condition approximate POI list 42 changes dynamically, and the user 15 selects a desired restaurant from among the restaurants included in the condition approximate POI list 42. In this case, the user 15 can select the restaurant name by placing a pointer, a cursor or the like on the name of the restaurant or touching it with a finger or the like. The condition approximate POI list 42 includes a detail button 43 as a selection means for selecting to refer to detailed information on the POI. Then, by selecting the detail button 43 corresponding to the desired restaurant, detailed information on the restaurant is displayed. The detail button 43 can be selected by placing a pointer, a cursor, etc., or touching with a finger or the like.

  When the user 15 selects the POI as described above and sets it as the destination, the process ends. The navigation device 11 searches for a route to the set destination and provides guidance for the searched route.

Next, a flowchart will be described.
Step S11: The registered POI search function is activated and a search based on impression information is selected.
Step S12 The impression information menu is displayed.
Step S13: Impression information is input.
Step S14: POI information matching the input impression information is displayed.
Step S15: POI is selected and set as the destination, and the process is terminated.

  As described above, in the present embodiment, the impression of the POI is obtained by the slide bar 33 corresponding to the viewpoint selected for the POI, and the slide guide 34 that indicates the impression of the POI by the position on the slide bar 33. Impression information with the ambiguity shown is input. For this reason, when registering a POI in the data part 12, impression information indicating the impression of the user 15 regarding the POI can be added and registered as attribute information of the POI, and the POI stored in the data part 12 can be registered. When searching, it is possible to search by impression information. Thereby, the user 15 can search for a POI from an ambiguous and sensory viewpoint, and can search for a POI that matches his / her preference and suits the mood of the place.

  In addition, even when a large number of POIs such as restaurants are registered and the impression of the POI at the time of registration has faded over time, the impression of the POI at the time of registration can be obtained by searching with the impression information. You can get it back.

  Further, when registering a POI or searching for a POI, the same impression information input screens 31 and 41 are displayed as shown in FIG. 1B and FIG. From the impression keywords shown in the column 32, the one indicating the viewpoint about the impression of the POI is selected, and the slide bar 33 and the slide guide 34 are used to input impression information having ambiguity indicating the impression of the POI. It has become. Therefore, the impression of POI can be input sensuously and easily in a short time.

  Next, a second embodiment of the present invention will be described. In addition, about the thing which has the same structure as 1st Embodiment, the description is abbreviate | omitted by providing the same code | symbol. The description of the same operation and the same effect as those of the first embodiment is also omitted.

  FIG. 6 is a diagram showing a screen for adding impression information to POI data in the second embodiment of the present invention, and FIG. 7 is a diagram showing a screen for searching for POI based on impression information in the second embodiment of the present invention. It is.

  First, when the user 15 operates the information acquisition device 14 to perform a registered POI input operation, a POI display screen 21 as shown in FIG. 6A is displayed on the display unit of the information acquisition device 14. . The POI display screen 21 is the same as that in the first embodiment, and a description thereof will be omitted.

  When the user 15 selects the POI displayed on the POI display screen 21 by operating the registration button 24, the impression information menu is displayed as shown in FIG. 6B. In FIG. 6B, 51 is an impression information input screen, and the user 15 inputs impression information through the impression information input screen 51. Here, the impression information input screen 51 is defined by the coordinate axis 52 corresponding to the selected viewpoint and the coordinate axis 52 as impression information input means for inputting the impression information about the viewpoint indicated by the selected impression keyword. A POI position indicating point 53 as a dot indicating an impression of the POI according to a position in the space to be displayed, and a pointer 54 for moving the POI position indicating point 53 are included. The impression information input screen 51 further includes an impression keyword field 32, a completion button 36, and a cancel button 37. Since these are the same as those in the first embodiment, description thereof is omitted. To do. FIG. 6B shows an example in which the restaurant shown in FIG. 6A is selected.

  Here, in the example shown in FIG. 6B, three impression keywords of “price”, “weight” and “number of menus” in the impression keyword column 32 are surrounded by a frame and indicate that they are selected. ing. The coordinate axis 52 displays a number corresponding to the number of selected impression keywords, and corresponds to “price”, “weight”, and “number of menus” in the example shown in FIG. A three-dimensional space defined by three coordinate axes 52 is shown. Note that since the impression information input screen 51 is a two-dimensional screen, it is practically impossible to display a space having four or more dimensions. Therefore, in this embodiment, the number of impression keywords that can be selected is 1 to 3.

  Each of the coordinate axes 52 indicates that the closer to the origin, the weaker the impression about the corresponding impression keyword, and the closer to the tip, the stronger the impression about the corresponding impression keyword. That is, the closer to the origin, the smaller the numerical value indicating the quality or quantity for the viewpoint indicated by the corresponding impression keyword, and the closer to the tip, the larger the numerical value indicating the quality or quantity for the viewpoint indicated by the corresponding impression keyword. In the example shown in FIG. 6B, the coordinate axis 52 corresponding to “price” means that the price is lower as it is closer to the origin, and the price is higher as it is closer to the tip. Further, the coordinate axis 52 corresponding to “feeling of weight” means that the closer to the origin, the lighter the light and the closer to the tip, the heavier. Further, the coordinate axis 52 corresponding to “number of menus” means that the closer to the origin, the smaller the number of menus, and the closer to the tip, the greater the number of menus.

  Each coordinate value of the POI position indicating point 53 represents an impression of each viewpoint that the user 15 has with respect to the restaurant as the POI. In the example shown in FIG. 6B, the coordinate value corresponding to “price” of the POI position indication point 53 is 2, the coordinate value corresponding to “feeling of weight” is 1, and “number of menus” is supported. The coordinate value is 2. From this, it can be seen that the user 15 feels that the restaurant is relatively cheap and light, and has the impression that the number of menus is relatively small. Each coordinate value is not a strict index but an ambiguous and sensory index.

  Then, the user 15 can determine the POI position indicating point 53 using the pointer 54. In this case, the POI position indicating point 53 may be dragged by the pointer 54, or the POI position indicating point 53 may be displayed at the position clicked by the pointer 54. Thereby, the impression about the viewpoint which the selected impression keyword which the user 15 has with respect to a restaurant can be shown ambiguously and sensuously.

  When the input of impression information is completed in this way, the user 15 operates the information acquisition device 14 to transfer the POI data with the impression information to the navigation device 11 as POI data with impression information. Then, the navigation device 11 registers the transferred POI data with impression information and stores it in the data section 12 as registered POI data with impression information.

  When a search based on impression information is executed, an impression information menu is displayed on the display unit of the navigation device 11 as shown in FIG. In FIG. 7A, reference numeral 61 denotes an impression information input screen, which is a screen on which the user 15 inputs impression information for search. In practice, the impression information shown in FIG. It has a screen configuration similar to the input screen 51, and includes an impression keyword column 32 indicating an impression keyword, a coordinate axis 52, and a POI position indication point 53. FIG. 7A shows an example in which a restaurant is selected as the POI.

  Then, the user 15 inputs impression information on the impression information input screen 61. In this case, a desired impression keyword is selected from the impression keywords shown in the impression keyword column 32, and impression information is input from the viewpoint indicated by the impression keyword. FIG. 7A shows a case where “price”, “weight”, and “number of menus” are selected as impression keywords, as in the case of the operation for registering the POI data with impression information described above. . In this case, POI position indication points 53 corresponding to all registered POIs with impression information on “price”, “feeling of weight”, and “number of menus” are displayed. The example shown in FIG. 7A is a three-dimensional space defined by three coordinate axes 52 corresponding to “price”, “weight” and “number of menus”. Are displayed in varying sizes to show perspective. That is, the POI position indicating point 53 positioned in front of the screen is displayed large, and the POI position indicating point 53 positioned in the back of the screen is displayed small.

  Subsequently, the user 15 shows the range to be listed in the three-dimensional space defined by the three coordinate axes 52 corresponding to “price”, “weight” and “number of menus” as shown in FIG. In this way, the list is displayed by the list range display 63 as a search frame. The list-up range display 63 indicates the range of POI position indicating points 53 to be searched according to the position in the space defined by the coordinate axis 52, and the POIs corresponding to all POI position indicating points 53 included in the range. Are listed. That is, the position and size of the list-up range display 63 indicate impression information about “price”, “feeling of weight”, and “number of menus” input as search conditions. Therefore, the position and size of the list-up range display 63 can be arbitrarily set and changed by the user 15. Note that the example shown in FIG. 7B is a three-dimensional space defined by the three coordinate axes 52 corresponding to “price”, “weight” and “number of menus”. Is displayed as a sphere.

  In the example shown in FIG. 7B, the coordinate value corresponding to “price” of the center point of the list-up range display 63 is 2.8, the coordinate value corresponding to “feeling of weight” is 0, and “menu The coordinate value corresponding to “number” is 3.2. The size of the list-up range display 63 is 2.5. From this, it can be seen that the user 15 wants to search for a restaurant whose price is somewhat low, does not feel the weight at all, and has a large number of menus. Each coordinate value is not a strict index but an ambiguous and sensory index.

  When the number of impression keywords selected from the impression keywords shown in the impression keyword column 32 is two, a two-dimensional space having two coordinate axes 52 as shown in FIG. Is displayed. Note that the example shown in FIG. 7C is a two-dimensional space defined by two coordinate axes 52 corresponding to “price” and “feeling of weight”. They do not need to be shown and are all displayed in the same size. The list-up range display 63 is displayed as a circle.

  In the example shown in FIG. 7C, the coordinate value corresponding to “price” of the center point of the list-up range display 63 is 4.2, and the coordinate value corresponding to “feeling of weight” is 3. 5 The size of the list-up range display 63 is 2.5. From this, it can be seen that the user 15 wants to search for a restaurant whose price is somewhat high and feels heavy. Each coordinate value is not a strict index but an ambiguous and sensory index.

  When the input of the impression information is completed, the POI information that matches the input impression information is displayed, and the condition matching POI list 64 is displayed as shown in FIG. The condition-matching POI list 64 is a list of POIs corresponding to all POI position indicating points 53 included in the range of the list-up range display 63. The user 15 selects a desired restaurant from the restaurants included in the condition matching POI list 64. In this case, the user 15 can select the restaurant name by placing a pointer, a cursor or the like on the name of the restaurant or touching it with a finger or the like. The condition-matching POI list 64 includes a detail button 43 as a selection means for selecting to refer to detailed information on the POI. Then, by selecting the detail button 43 corresponding to the desired restaurant, detailed information on the restaurant is displayed.

  As described above, in the present embodiment, the coordinate axis 52 corresponding to the viewpoint selected for the POI, and the POI position indication point as a dot indicating the impression of the POI by the position in the space defined by the coordinate axis 52 53, impression information having an ambiguity indicating an impression of POI is input. Further, using the list-up range display 63 as a search frame indicating the range of the POI position indicating point 53 to be searched according to the position in the space, the POI data with impression information is searched by the impression information having ambiguity. It has become.

  That is, from the impression keywords shown in the impression keyword column 32, the one indicating the viewpoint of the POI impression is selected, and the impression from the viewpoint is input by the position in the space defined by the coordinate axis 52 corresponding to the viewpoint. It is like that. Therefore, the impression of POI can be input sensuously and easily in a short time.

  Next, a third embodiment of the present invention will be described. In addition, about the thing which has the same structure as 1st and 2nd embodiment, the description is abbreviate | omitted by providing the same code | symbol. Also, the description of the same operations and effects as those of the first and second embodiments is omitted.

  FIG. 8 is a diagram showing a screen for adding impression information to POI data in the third embodiment of the present invention, and FIG. 9 is a diagram showing a screen for searching for POI based on impression information in the third embodiment of the present invention. It is.

  First, when the user 15 operates the information acquisition device 14 and performs a registered POI input operation, a POI display screen 21 as shown in FIG. 8A is displayed on the display unit of the information acquisition device 14. . The POI display screen 21 is the same as that in the first and second embodiments, and a description thereof will be omitted.

  When the user 15 operates the registration button 24 to select the POI displayed on the POI display screen 21, the impression information menu is displayed as shown in FIG. 8B. In FIG. 8B, reference numeral 71 denotes an impression information input screen, and the user 15 inputs impression information through the impression information input screen 71. Here, the impression information input screen 71 serves as an impression information input means for inputting impression information about the viewpoint indicated by the selected impression keyword, and is an index corresponding to the selected viewpoint that is radially extended from the center. A radar chart including an axis 72, an index value point 73 plotted on the index axis 72 and indicating an impression of POI according to a position on the index axis 72, and a broken line 74 connecting the index value points 73 on each index axis 72 (A spider web graph) and a pointer 75 for moving the index value point 73 are included. The impression information input screen 71 further includes an impression keyword field 32, a completion button 36, and a cancel button 37. Since these are the same as those in the first and second embodiments, Description is omitted. FIG. 8B shows an example in which the restaurant shown in FIG. 8A is selected.

  Here, in the example shown in FIG. 8B, “price”, “accompanied person”, “preparation of heart”, “fashion feeling”, “feeling of weight”, and “number of menus” in the impression keyword field 32 are displayed. Six impression keywords are surrounded by a frame, indicating that they have been selected. The index axis 72 displays a number corresponding to the number of selected impression keywords. In the example shown in FIG. 8B, “price”, “accompaniment”, “preparation of heart”, A radar chart having six index axes 72 corresponding to “feeling of fashion”, “feeling of weight” and “number of menus” is shown. Since the number of index axes 72 in the radar chart may be any number, in this embodiment, the impression keyword can be selected no matter how many.

  Each of the index axes 72 indicates that the closer to the center, the weaker the impression about the corresponding impression keyword, and the closer to the tip, the stronger the impression about the corresponding impression keyword. That is, the closer to the center, the smaller the numerical value indicating the quality or quantity for the viewpoint indicated by the corresponding impression keyword, and the closer to the tip, the larger the numerical value indicating the quality or quantity for the viewpoint indicated by the corresponding impression keyword. In the example shown in FIG. 8B, the index axis 72 corresponding to “price” means that the price is lower as it is closer to the center, and the price is higher as it is closer to the tip. Further, the index axis 72 corresponding to “accompanied person” means that the closer to the center, the less suitable for the date, and the closer to the tip, the more suitable for the date. Furthermore, the index axis 72 corresponding to “preparation of the heart” means that the closer to the center, the less easy it is, and the closer to the tip, the easier it is to feel. Furthermore, the index axis 72 corresponding to “fashion feeling” means that the closer to the center, the less fashionable feeling is, and the closer to the tip, the more fashionable. Further, the index axis 72 corresponding to “feeling of weight” means that the closer to the center, the lighter the light, and the closer to the tip, the heavier. Further, the index axis 72 corresponding to “number of menus” means that the closer to the center, the smaller the number of menus, and the closer to the tip, the larger the number of menus.

  Each value of the index value point 73 represents an impression of each viewpoint that the user 15 has with respect to the restaurant as the POI. In addition, the polygonal shape formed by the broken line 74 indicates a balance of impressions about each viewpoint that the user 15 has with respect to the restaurant. Further, the size of the polygon formed by the broken line 74 indicates the impression of each viewpoint that the user 15 has with respect to the restaurant, like the value of the index value point 73. The index value point 73 and the shape and size of the polygon formed by the polygonal line 74 are not strict indices but ambiguous and sensory indices.

  Then, the user 15 can determine the index value point 73 using the pointer 75. In this case, the index value point 73 may be dragged by the pointer 75, or the index value point 73 may be displayed at the position clicked by the pointer 75. Thereby, the impression about the viewpoint which the selected impression keyword which the user 15 has with respect to a restaurant can be shown ambiguously and sensuously.

  When the input of impression information is completed in this way, the user 15 operates the information acquisition device 14 to transfer the POI data with the impression information to the navigation device 11 as POI data with impression information. Then, the navigation device 11 registers the transferred POI data with impression information and stores it in the data section 12 as registered POI data with impression information.

  When a search based on impression information is executed, an impression information menu is displayed on the display unit of the navigation device 11 as shown in FIG. In FIG. 9A, reference numeral 81 denotes an impression information input screen, which is a screen on which the user 15 inputs impression information for search. In practice, the impression information shown in FIG. A search selection means for executing a search of an impression keyword column 32 indicating an impression keyword, an index axis 72, an index value point 73, a broken line 74, a pointer 75, and impression information. And a cancel button 83 as cancel selection means for canceling the search information input operation. FIG. 9A shows an example in which a restaurant is selected as the POI.

  Then, the user 15 inputs impression information on the impression information input screen 81. In this case, a desired impression keyword is selected from the impression keywords shown in the impression keyword column 32, and impression information is input from the viewpoint indicated by the impression keyword. FIG. 9A shows an impression keyword “price”, “accompaniment”, “preparation of heart”, “fashion feeling”, “weight”, as in the case of the operation for registering the POI data with impression information described above. This shows a case where “feel” and “number of menus” are selected. In this case, a radar chart of impression information entered for search is displayed for “price”, “accompaniment”, “preparation of heart”, “fashion feeling”, “feeling of weight” and “number of menus”. Yes. In this case, the impression information is input in the same manner as the impression information is added to the POI data.

  Subsequently, when the input of impression information is completed, the user 15 selects the search button 82 to search for a POI that matches the input impression information. When canceling the input item, the cancel button 83 is selected. The search button 82 and the cancel button 83 are operated when the user 15 places a pointer, a cursor or the like or touches it with a finger or the like.

  When the search is completed, the POI information that matches the input impression information is displayed, and the condition-matching POI list 84 is displayed as shown in FIG. 9B. The condition-matching POI list 84 is a list of POIs that match the input impression information. If there is no POI that completely matches the input impression information, FIG. As in the example shown, POIs to which impression information approximate to the input impression information is listed. Also, on the impression information comparison display screen 85, a radar chart of a restaurant as a POI to which approximate impression information displayed in the condition-matching POI list 84 is given is a radar chart of impression information input for search. It is displayed in a state that can be compared. In FIG. 9B, 86a to 86d are radar charts for each of the restaurants (1) to (4) to which approximate impression information displayed in the condition matching POI list 84 is given. Since the radar charts 86a to 86d can grasp the impression information given to the restaurants (1) to (4) displayed on the condition matching POI list 84, the user 15 can select a restaurant closer to his / her wish. You can choose. The condition matching POI list 84 includes a detail button 43 as a selection means for selecting to refer to detailed information on the POI. Then, by selecting the detail button 43 corresponding to the desired restaurant, detailed information on the restaurant is displayed. The POI to be listed is a POI having a high degree of coincidence by comparing the radar chart graphic of impression information input for search with the radar chart graphic of impression information in each POI. For example, a predetermined number of POIs are listed in descending order of coincidence. When there are a plurality of POIs having the same degree of matching, the degree of matching of the impression information with the keyword having a high priority is compared, and the POI having the high degree of matching is ranked higher. The priority is set in advance by the user 15 for each keyword.

  Thus, in the present embodiment, the index axis 72 corresponding to the viewpoint selected for the POI, the index value point 73 indicating the impression of the POI according to the position on the index axis 72, and the index axis 72 Impression information having an ambiguity indicating an impression of POI is input by a radar chart including a broken line 74 that connects the index value points 73. Therefore, the impression of POI can be input sensuously and easily in a short time. Also, the retrieved POI impression information can be easily compared with other POI impression information and impression information input for retrieval.
