  The search term list data file 59 is a file that stores search term list data. The search word list data stores the correspondence between readings and display character strings, and is used when the user specifies the display character strings of readings input as search words by the user.

FIG. 2 is a diagram illustrating an example of a logical configuration of search term list data.
The search term list data file 59 includes items such as “reading”, “number of displays”, and “display”.
The item “reading” is a reading for matching (specifying a matching item) with a reading input by the user as a search term. For example, “Tokyo”, “Tokyo”, and the like are read in the point information data file 58. This corresponds to the separator.

The item “number of displays” is the number of “displays” of the next item. This is to inform the computer of the number of data stored in the item “display”.
That is, the number of data stored in the item “display” is, for example, three data of “pottery”, “winter season”, and “registration” are stored for “Tokyo”, and “Tokyo” is stored in “Tokyo”. On the other hand, one piece of data “Tokyo” is stored.
As described above, since the number of data stored in the item “display” is different for each item “reading”, the range corresponding to the item “reading” in the array of data stored in the storage medium. You need to let your computer know if it is.

The item “display” stores a display character string corresponding to the item “reading”.
The display character string stored in the item “display” is included in the display character string of the spot name in the spot information data file 58, and in the spot information data file 58 for the reading “Tokyo”. There is no “Tokyo” registered.
The search term list data configured as described above is used when a display character string candidate is presented for a reading input by a user.
For example, when the user inputs “toki” as a search term, the navigation apparatus 1 displays “pottery”, “winter”, “registration”, and the like as display character string candidates, and indicates what the user intended. Can be specified.

FIG. 3 is a diagram showing an example of the appearance of the display 42 from which the spot name search screen 60 has been searched.
A touch panel constituting the input device 41 (FIG. 1) is formed on the surface of the display 42. When the user touches a button or the like displayed on the display 42, information corresponding to the button is input to the navigation device 1. Can be done.

Although not shown, the point name search screen 60 includes a search area setting menu so that the user can select a desired search area.

The navigation device 1 searches for a spot name in the area set in the area input field 62.
The area correction button 73 is a button to be touched when correcting the search area set in the area input field 62.
When the area correction button 73 is touched, the search area set in the area input field 62 can be corrected.

The genre input field 64 is a field for setting a genre for searching for a place name. The genre includes, for example, “restaurant”, “hotel”, “amusement park”, “tourist spot”,.
Although not shown, the point name search screen 60 includes a genre setting menu so that the user can select a desired genre.

The navigation device 1 searches for a spot name using the genre set in the genre input field 64.
The genre correction button 63 is a button that is touched when correcting the genre set in the genre input field 64.
When the genre correction button 63 is touched, the genre set in the genre input field 64 can be corrected.
As described above, the navigation device 1 reduces the search processing amount by performing a search after narrowing down the name of a point to be searched using an area and a genre.

The search result display column 66 is a column for displaying a list of searched spot names. In the example shown, up to 5 items can be displayed at a time.
The search result display column 66 functions as a target presentation unit that presents a target searched by the search unit.
In the present embodiment, the presentation method is displayed. However, for example, the presentation method can be presented by voice.
Each column of the search result display column 66 functions as a target selection means for selecting a target displayed in each column, and the point name is input by touching the point name displayed in each column. A search result corresponding to the search term, for example, a destination search in a navigation device, is determined as a destination.

In the spot name displayed in the search result display column 66, the display character corresponding to the keyword is highlighted.
For this reason, the user can easily recognize which part of the spot name matches the search term input by the user.

The part of the display character string corresponding to this reading can be specified by the correspondence information in the point information data file 58 described above.
In the present embodiment, highlighting is performed in order to improve the visibility for the user, but this is not necessarily performed.

The detail button 67 is displayed for each spot name, and when the user touches the detail button 67 for the desired spot name, the navigation apparatus 1 searches the spot information data file 58 for spot information corresponding to the spot name and displays it. 42.
The previous button 74 and the next button 77 are buttons for scrolling down and scrolling up the point names in the search result display field 66 one by one.
The page buttons 75 and 76 are buttons for scrolling down and scrolling up the point names in the search result display field 66 in page units, respectively.

The scroll bar 71 represents the position of the currently displayed result among all the search results, and can be scrolled up or down by touching and dragging the scroll bar 71.
In the number display column 65, the number of searched spot names is displayed. In this example, there are 3028 cases.

A display character string selection area 80 is formed at the bottom of the point name search screen 60, and five buttons of selection buttons 81a to 81e are displayed in the area. Hereinafter, when the selection buttons 81a to 81e are not particularly distinguished, they are simply referred to as a selection button 81.
Each selection button 81 displays a display character string corresponding to the reading input in the reading input field 61.
In this case, the navigation device 1 searches and displays a display character string corresponding to reading in the search word list data file 59.

The selection buttons 81a to 81e are included in the searched target (point information), and function as candidate presentation means for presenting a list of display character string candidates corresponding to the reading input as a search word, and a selection button. .
That is, the display character strings displayed on the selection buttons 81a to 81e are display character string candidates that are considered to be intended when the user inputs a reading.

  Since there are five selection buttons 81, when the number of display character strings that match the reading is less than five, the navigation device 1 further displays the display character corresponding to the next reading in the search word list data file 59. Also display columns.

  For example, in the example of FIG. 3, for the reading “Touki”, the navigation device 1 searches the search word list data file 59 for the display character strings “Pottery”, “Winter”, and “Registration”. The columns are displayed on the selection button 81a, the selection button 81b, and the selection button 81c in the order of search.

  In this way, there are three display character strings corresponding to the reading “Touki”, and there are two spaces in the selection button 81. Therefore, the navigation device 1 further displays the next two displays in the search word list data file 59. The character strings “Tokyu” and “Tokyo” are searched and displayed on the selection button 81d and the selection button 81e.

When the user touches any one of the selection buttons 81, the touch panel detects this, and the user can select and specify any display character string.
Here, the selection buttons 81a to 81e function as a selection receiving unit that receives selection of the presented display character string.
When the selection button 81 is selected, the navigation device 1 sets the display character string of the selection button 81 as an element for filtering the search result.

And the navigation apparatus 1 filters a search result as follows by selection of the selection button 81. FIG.
When the selection button 81 is touched once, the navigation device 1 narrows down the search result by extracting the search result including the display character string from all the search results, and displays the narrowed search result in the search result display column 66. To do.

As described above, the navigation device 1 includes an extraction unit that extracts, from the searched target (search result, that is, searched point information), the one that includes the display character string that has been selected by the selection button 81. Output means for outputting the extracted object to the search result display field 66 is provided.
If the number of display character strings that match the reading is five or more, the selection button 81 is not displayed on one screen. Therefore, a scroll button or a switch button is provided around the selection button 81 to display other character strings. It is also possible to perform.

Further, when the same selection button 81 is touched twice in succession, the navigation device 1 narrows down search results that do not include the display character string from all search results and displays them in the search result display column 66.
In this case, the second touch of the selection button 81 corresponds to accepting non-selection that the display character string presented on the selection button 81 is not selected, and the navigation device 1 selects the display character string from all search results. The target is output excluding the inclusions. That is, the navigation device 1 outputs a target that has not been extracted at the time of the first touch.

Furthermore, when the same selection button 81 is touched three times in succession, the navigation device 1 displays all search results in the search result display column 66.
Thus, every time the same selection button 81 is selected, the navigation device 1 displays a screen for displaying all search results, a screen when a display character string is selected, and a screen when the display character string is not selected. Is displayed cyclically.

For example, when the user touches the selection button 81a on which “Pottery” is displayed once, the navigation apparatus 1 extracts the item including “Pottery” from all search results and displays it in the search result display column 66. When touched once, the search result display column 66 is extracted from all the search results and does not include “pottery”. When touched three times, all search results are displayed in the search result display column 66 and returned to the initial state. Return.
In this embodiment, the selection / non-selection of the display character string is set by continuously touching the selection button 81. However, the selection / non-selection of the display character string is accepted depending on the time during which the selection button is touched. Alternatively, a button for setting selection / non-selection may be provided so that selection / non-selection of the display character string may be received from the user.

FIG. 4 is a diagram showing a point name search screen 60a when the user touches the selection button 81a on which “Pottery” is displayed once.
As shown in FIG. 4, in the search result display column 66, “Ceramics / Pottery Class”, “Kato Pottery Class”, “Pottery Sales Center”, etc., display character string “Pottery” from all search results. "Is extracted and displayed.
And the number display column 65 is 329, and it can be seen that the number is reduced from 3028 (FIG. 3) to 329.

In addition, the display state of the selection button 81 changes, for example, the display color changes or the display blinks so that it can be visually confirmed that the selection button 81 has been selected once.
In this state, when the selection button 81b to the selection button 81e are selected, the navigation device 1 narrows down the items including the display character string of the selection button 81 selected from all the search results and displays them in the search result display column 66. indicate.

FIG. 5 is a diagram showing the point name search screen 60b when the user touches the selection button 81a on which “Pottery” is displayed on the point name search screen 60a (FIG. 4).
As shown in FIG. 5, the search result display field 66 includes “Tokyo Station Information Center”, “XX Registration Office”, “XX Automobile Winter Test Course”, etc. Those that do not contain the display character string "Pottery" are extracted and displayed.
And the number display column 65 is 2699, and if 329 cases of the point name search screen 60a (FIG. 4) are added, it will become 3028 cases of the point name search screen 60 (FIG. 3).

In addition, the display state of the selection button 81 is changed so that the selection button 81 can be visually recognized, for example, the display color changes or blinks.
In this state, when the selection button 81b to the selection button 81e are selected, the navigation device 1 narrows down the items including the display character string of the selection button 81 selected from all the search results and displays them in the search result display column 66. indicate.
When the selection button 81 is selected again, the navigation device 1 displays the spot name search screen 60 (FIG. 3).

Next, search processing performed by the navigation device 1 will be described using the flowchart of FIG.
First, the navigation device 1 accepts an input of a search term by accepting an input of a reading in the reading input field 61 (step 5).
When the input of the search word is not completed (step 10; N), the navigation device 1 returns to step 5 and continuously accepts the input of the search word.

On the other hand, when the input of the search word is completed (step 10; Y), the navigation device 1 searches the spot information data file 58 for spot information including the reading (step 15).
Next, the navigation device 1 reads the display character string of the spot name from the searched spot information (Step 20), and displays it in a list in the search result display column 66 of the spot name search screen 60 (Step 25).
When the navigation device 1 receives selection of the selection button 81 on the point name search screen 60 (step 30; selection button), it sets the display character string of the selected selection button 81 as a filter element (step 35). ).

  Next, the navigation device 1 determines the number of times that the selection button 81 has been selected. If it is the first time, the navigation device 1 extracts point information including the display character string set in the filter, and the second time. If there is, the point information not including the display character string is extracted, and if it is the third time, the search result is narrowed down by extracting all the point information from the search result (step 40).

And the navigation apparatus 1 returns to step 25, and displays the spot name search screen 60, the spot name search screen 60a, or the spot name search screen 60b using the narrowed-down result.
On the other hand, when the selection button 81 is not selected in step 30 and another button is selected (step 30; other button), the navigation device 1 performs normal processing.

The following effects can be obtained by the present embodiment described above.
(1) Display character string candidates corresponding to readings input as search terms can be displayed in a selectable list.
(2) When a candidate for a display character string is selected, it is possible to narrow down ones including the display character string from all search results.
(3) It is also possible to select non-selection of display character string candidates, and in this case, it is possible to narrow down those that do not include the display character string from all search results.
(4) The point information searched by narrowing down all search results can be reduced, and the user can find the point information intended by the user more easily.
(5) By providing a filtering function (a function for displaying / hiding only specified ones) by a word including a condition (reading) input by the user when displaying a list of searched objects. Non-applicable point information can be displayed / erased, and the number of cases displayed in the list can be searched.

As mentioned above, although one embodiment of the character selection means, the navigation device, and the character selection program of the present invention has been described, the present invention is not limited to this, and various modifications are possible.
For example, in the described embodiment, the selection button 81 configured with a display and a touch panel is configured to function as a candidate presentation unit and a selection reception unit.
On the other hand, the candidate presentation unit and the selection receiving unit may be configured separately.

As a result, as in the case of touching the selection button 81a on which the display character string “Pottery” is displayed on the point name search screen 60 of FIG. 3, the search result display column 66 displays “Pottery / Pottery Class”, “Kato Pottery Class”, “Pottery Sales Center”, etc., which include the display string “Pottery” are extracted and displayed from all search results.
Note that all search results are sorted and held for each display character string, and the number of candidates corresponding to the selected candidate display character string is the displayable number of search result display fields 66 (in the present embodiment and the modification example). If the number is less than 5), the corresponding candidate for the next display character string may be displayed continuously.

The selected candidate field 82a is displayed separately from the other candidate fields 82b and 82c in order to clearly indicate that the displayed character string “Pottery” is selected.
In the example of FIG. 8, the display frame of the selected candidate field 82 is displayed thicker than the others, but the selected display character string is displayed in a different color from other display character strings, or candidates You may make it blink the frame of the column 82 or display it with high brightness.

When the user touches the “next keyword” button 90 on the point name search screen 60 of FIG. 8, the display character string “winter season” displayed in the next candidate field 82b is selected.
Then, the spot names including this display character string “winter season” are extracted from all search results (searched spot names) and displayed in the search result display field 66.

Note that the “next keyword” button 90 serving as a selection receiving unit according to the first modification selects the display character strings searched from the search word list data file 59 in order from the top, and the head after the last display character string. The display character string is returned to and selected sequentially so as to circulate backward.
On the other hand, a “previous keyword” button that sequentially selects in the reverse direction (forward) may also be displayed.
In this case, in the state of FIG. 7 in which no display character string is selected, the display character string in the candidate field 82a is displayed regardless of whether the “next keyword” button or the “previous keyword button” is first touched. Selected. Thereafter, the backward or forward display character string is selected in accordance with the touched “next keyword” button or “previous keyword” button.

FIG. 9 is a diagram showing a spot name search screen in the second modification.
In the second modification, tab buttons 83a to 83e are provided as shown in FIG. The display character strings “Pottery”, “Winter”,... Are displayed on the tab button 83, and each tab button 83 is configured to be selectable by a touch panel. Make it work. The tab button 83 also functions as a selection button.

When each tab button 83 is touched (selected), a point name is extracted from all search results using the display character string displayed on the tab button 83 as a filtering element.
The tab area of the selected tab button 83 is displayed at the top, the name of each extracted point is displayed in the search result display field 66, and the previous button 74, the next button 77, and the page are displayed on the left side of the tab area. Buttons 75 and 76 are displayed. The previous button 74, the next button 77, and the page buttons 75 and 76 may be arranged outside the respective tab areas as common buttons.

There are displayed p tab buttons 83 (in this second modification, five as shown in FIG. 9).
When the number of display character strings corresponding to the input reading (keyword) is larger than p, the front tab button 85a and the rear tab button 85b are displayed on both sides of the tab buttons 83a to 83e in a selectable manner. When the number is less than p, it is not displayed or lightly displayed and cannot be selected.
When the rear tab button 85b or the front tab button 85b is touched, each tab button 83 displays the next p display character strings.

In addition, in each modification demonstrated in FIGS. 7-8, like the embodiment described, what part is displayed by highlighting a display character string about each point name displayed on the search result display column 66. It is possible to easily recognize whether or not matches the input.
Similar to the embodiment, this highlighting may be displayed in the same manner as other characters without being performed, and the user may be able to select display or non-display.

In the first embodiment and the second embodiment described above, the navigation device (character selection device) assumed to be used in Japan has been described. That is, the input device 41 for inputting a keyword is composed of Japanese syllabary keys that are Japanese input units, and the destination data file 56 and the keyword data file 58 store data related to destination search in Japan. The specification navigation device has been described.
However, the environment in which the navigation device is used is not limited to Japan. By making the specification of the input device 41 and each data correspond to the region, the input function using the keyword data described above can be used in various countries.

For example, as an example of a navigation device (destination input device) for use outside Japan, a device having an alphabet key corresponding to English (English character) input may be used.
Furthermore, the apparatus may be adapted to input any language such as German, Spanish, French, Arabic, Chinese, Korean, Russian. For example, in the case of a navigation device that supports Chinese input, the input device 41 includes an input keyboard 422 that supports Chinese pinyin input.

The language to be input need not necessarily correspond to the country (region) to be used for the navigation device. For example, a navigation device that supports German input may be used in France. In this case, in the destination data file 56, the keyword data file 58, etc., data to be searched when performing destination search, that is, data to be compared with input characters (for example, destination name, keyword, address, etc.) ) Stores data corresponding to the input language.
In addition to the input language, data corresponding to the language of the country (region) to be used may be stored in the data to be searched.
In addition, data that is not a search target when performing destination search, for example, additional information data, need not store data corresponding to the input language. For example, data corresponding to the input language, data corresponding to the language of the country (region) to be used are stored as the data that is not the search target, Data corresponding to both languages of a given country (region) may be stored.

It is a system configuration figure of a navigation device. It is the figure which showed an example of the logical structure of search term list data. It is the figure which showed an example of the point name search screen. It is the figure which showed the point name search screen when a user touches a selection button once.
