In FIG. 4, character input keys 31 to 40 are keys for selecting each alphabet or the like. For example, with the character input key 31, three alphabets of A, B, and C can be selected. When the character input key 31 is touched once, A is selected, and when the character input key 31 is touched twice consecutively, B is selected.
Touching three times consecutively selects C. The same applies to the other character input keys 32-39. In the screen shown in FIG. 4, first, "Choose a City" is displayed by the operation guide message 45, and the information selection display key 4 is displayed in order from the city name starting with A as an initial screen.
1 to 44 are displayed. A city name starting with B is displayed on the information selection key 43. This is because, in the information on city names stored in the map database device 8, there are only two city names starting with A as a whole. There are city names that start with B, so they are displayed.

In FIG. 4, character input keys 31, 32, 33
Only the solid line is surrounded by a solid line and the other character input keys 34 to 40 are surrounded by a broken line because there is no city name starting with the character input key surrounded by a broken line (not stored in the map database device 8). That's what it means. Character input keys 31, 3
The alphabets A, B, D, E,
Although only F, G, and H are highlighted characters, there is no city name that starts with a character other than the highlighted characters (not stored in the map database device 8). In this way, an unnecessary alphabet can be immediately recognized, and even if an unnecessary character input key is touched, no operation is performed. Therefore, the operation is easy and reliable. On an actual display screen, a color, brightness, or the like may be changed instead of a solid line, a broken line, or emphasized characters. The key 46 is an information display feed key for scrolling up or down the contents displayed on the information selection display keys 41 to 44.

Next, the case where the city name BERLIN (Berlin) is selected will be described. In the initial screen of FIG. 4, when the character input key 31 is touched twice consecutively, the alphabet B is selected, and the city names starting with B are listed on the information selection display keys 41 to 44 (not shown). FIG. 5 is a diagram illustrating a case where E is selected after B. B
When the character name confirming the character input is touched when the city names starting with "?" Are listed, the alphabet B is determined and the next alphabet can be selected.
FIG. 5 shows the screen when the character input key 32 is touched twice consecutively and E is selected. Since E has not been determined yet, city names starting with B are listed in the information selection display keys 41 to 44. In FIG. 5, the alphabets of the character input keys 34, 38 and 39 indicated by broken lines and the non-emphasized alphabets of the character input keys indicated by solid lines mean that the second alphabet of the city name starting with B does not exist. That is, in the city name data stored in the map database device 8, the next alphabet after the city name starting with B is only the city name of A, E, I, O, R, U, etc (the map database device 8). Is not stored in the).

The information selection display key 42 shown in FIG.
Since IN is displayed, by touching the BERLIN information display key 42, the city name BERLIN is selected. Further, when BERLIN is selected, a street name (street) selection screen (not shown) is displayed, and the street names and the like in the street selection screen can be selected in alphabetical manner. Then, when a street name is selected, the selected BERL is selected.
The INE street (street) is displayed on the screen together with the map, and the destination can be set.

A key 47 is a character input correction key.
When touched twice, the character returns to the previous alphabet and the character input keys 31 to 40 are operated again to correct the character (alphabet). The key 48 is a back screen key for returning to the previous screen.

As described above, while inputting alphabets for selecting information, a list of candidates indicated by the input alphabets can be simultaneously viewed on the same screen. In addition, a list of candidates starting with the alphabet input up to that time can be viewed without necessarily inputting all the alphabets of the target item. Therefore, if a candidate item appears in the list even during character input, the target item can be selected at that time.

FIG. 8 is a facility information screen which is entered when the facility information key 12 is touched on the screen of FIG. The facility information is a screen that is selected when obtaining information about facilities such as a gas station and a hotel on a road map. Further, in the screen of FIG.
When 2 is selected, the screen shown in FIG. 6 is displayed. In FIG. 6, the facility name can be selected by inputting the alphabet in the same manner as in the case of setting the destination described above. In FIG. 6, B is input after the alphabet A is determined. Since B is not yet determined, the facility names starting with A are listed. Information selection display key 4
In FIG. 1, the facility name (example of hotel) is surrounded by a thick solid line to indicate that an ABC hotel is selected. At this time, in the detailed information display area 51 in the same screen, an address as detailed information of the hotel corresponding to the selected facility name is displayed. In the specific information display area 52, a telephone number as specific information is displayed. A key 53 is a detailed information feed key, and shifts or returns the display to display detailed information that cannot be displayed in the detailed information display area 52. By operating the information display feed key 46, it is possible to scroll up the subsequent facility name.

In the screen of FIG. 6, there is only one facility name starting with the alphabet AB. Therefore, when B is determined, A
Only BC hotels will be displayed. However, it is not always necessary to display only the characters starting with the determined character. For example, it is conceivable that the input character is returned by one character, and those not selected are continuously listed, and when the input is completed, the character is further returned by one character and the list is similarly listed.

When another information selection display key is touched on the screen shown in FIG. 6, for example, when the information selection display key 42 is touched, the selection of the information selection display key (enclosed by a thick solid line in FIG. 6) is performed. Move on to the display key 42, the facility name AC
A detailed information of A HOTEL includes a detailed information display area 51,
It is displayed in the specific information display area 52. Also, the information selection display key can be moved by the information information display feed key 46, and further scrolled up or down. In this case, the detailed information corresponding to the movement of the selection is displayed in the detailed information display area 51 and the specific information display area 52. Further, when scrolling up or down, the information at the bottom or top is displayed. The selection display key is selected, and the corresponding detailed information is displayed.

As described above, when trying to select information having detailed information, the information name can be selected by inputting alphabets, and at the same time, the detailed information is displayed on the same screen. The user can easily search for the desired information while viewing the contents. For example, even if a gas station having the same name is selected by alphabet entry and listed, it is possible to easily search for a desired gas station while viewing detailed information. In this case, it is not necessary to switch to a screen for displaying detailed information for each item.

Although the above embodiment has been described with reference to the case of having an alphabetic information name, the present invention can be similarly applied to kana characters, katakana characters, and kanji characters. Also, characters in other foreign languages may be used.

The present invention has the following effects because it is configured as described above. According to the first aspect of the present invention, it is possible to simultaneously view a list of candidates indicated by the input alphabet on the same screen while inputting an alphabet for selecting information. In addition, a list of candidates starting with the alphabet input up to that time can be viewed without necessarily inputting all the alphabets of the target item. Therefore, if a candidate item appears in the list even during character input, the target item can be selected at that time. It is not necessary to switch the screen for displaying the list every time. As described above, the information item to be selected can be easily selected. According to the second aspect of the invention, in addition to the effect of the first aspect, it is possible to easily search for the target information while viewing the content of the detailed information of the information having the detailed information.
