Target names such as place names and facility names, telephone numbers and addresses, registered locations,
A destination is set using a road name or the like (step S1). Next, the current position is detected by the current position detection device 2 and a map around the current position is displayed around the current position. It is displayed (step S2), and a route search from the current position to the destination is performed (step S3). When the route is determined, the route guidance / display is repeated until the vehicle arrives at the destination while tracking the current position by the current position detecting device 2 (step S4). If a detour setting is input before arriving at the destination, a search area is set, a re-search is performed in the search area, and route guidance is repeated until the vehicle arrives at the destination.

Next, an item selection method on the touch panel according to the present invention will be described. FIG. 5 shows a road map display screen centering on the current location in a display device provided with a touch panel. On the screen, an azimuth instruction mark and a scale unit distance are displayed, and some touch switches are displayed. The peripheral search touch switch is a switch for searching for facilities near the current location, the detailed touch switch is a switch for displaying a detailed map, and the all-routes touch switch is for re-searching a new route to the destination. Switch for re-searching is a switch for re-searching by peripheral search, a wide area touch switch is a switch for displaying a wide area map, and a return touch switch is a switch for returning the display to the route guidance initial screen. is there.

Here, when the peripheral search switch is operated,
At the bottom of the screen, facility selection switches such as convenience stores, parking lots, gas stations, family restaurants, banks, etc. are displayed. For example, when a convenience store is selected, as shown in FIG. 6, a landmark of a convenience store near the current location is displayed at that position. In this landmark display method, for example, a landmark in a predetermined area larger than the currently displayed map screen is searched for and acquired from the data shown in FIG. Then, the mark is drawn by superimposing it on the map based on the landmark drawing data with the acquired coordinates of each landmark as the center. Here, when the landmark F is operated, as shown in FIG.
Is displayed on the road map display screen with the mark F at the center of the screen, and when the passing point or the destination setting switch is operated, the facility of the landmark F is displayed. Is set as a passing point or a destination. The cross mark displayed overlapping the landmark F is a cursor, and indicates that the center of the cursor is a position where a point can be set. By operating the registration switch, the facility represented by the landmark F is registered. When the peripheral search switch is operated again on the screen of FIG. 6, the screen is changed to a screen on which the facility selection switch on the lower side of FIG. 5 is displayed. When the screen is to be restored, the release switch may be operated, although not shown. In the above description, the selected landmark F is displayed at the center of the screen. However, it is not always necessary to display the selected landmark F at the center of the screen.
In, the business hours, business contents, telephone numbers, etc. of the facilities of the landmark F may be displayed.

Next, referring to FIGS. 8 to 10, a description will be given of the selection by the touch switch when the landmarks are densely displayed. FIG. 8 is a display screen when a predetermined item selection switch is operated while the facility selection items of FIG. 5 are displayed. The landmarks Y, K, M, and P are densely displayed in the upper right portion of this screen. When the user touches the landmark K to operate the landmark K, the landmark Y is selected by mistake. If so, the screen is centered on the landmark Y, and a cursor indicating that the landmark Y has been selected is displayed over the landmark Y. In this state, as shown in FIG. 9, when the switch operation is performed again, the probability of selecting the landmark Y selected last time decreases, and the landmark K
Is selected, and the cursor is displayed over the landmark K. The process of lowering the selection probability of the landmark 7 selected last time at the time of an erroneous touch will be described in detail below.

FIG. 10 is a view for explaining landmark coordinates (east longitude and north latitude of the facility represented by the landmark) and reaction points of the touch panel. In FIG. 10, small black dots indicate reaction points on the touch panel, hatched circles indicate landmark coordinate positions Y, K, M, and P, and black circles indicate touch reaction points O. When a reaction point O is detected when a finger is operated as shown in the figure, a coordinate difference (distance) from the coordinate position of the displayed landmark is calculated. The landmark for which the coordinate difference is to be calculated is, for example, a landmark within a predetermined rectangular area centered on point O. In the initial selection, Y closest to the O point is selected. After that, when the vicinity of the O point touched last time is touched again, for example, a rectangular area centered on the O point touched last time is stored. If there is a touch in that area, the distance between the current reaction point and the previously selected Y point is made difficult to select by multiplying or adding a predetermined coefficient. As a result, a target K point is selected. In addition, in the figure, the touch panel reaction point is provided finely with respect to the size of the finger, and the probability of erroneous operation is small, but when the touch panel reaction point is coarse, the probability of erroneous operation increases, so in such a case, Is particularly effective.

Next, with reference to FIGS. 11 and 12, a flow of a peripheral search process according to the present invention will be described. In FIG. 11, when the peripheral search key displayed on the screen as shown in FIG. 5 is operated, a facility selection item is displayed on the screen, and when a predetermined genre is selected from the selection item (steps 11 and 12). The landmark corresponding to the selected genre is searched and displayed on the map (step 1).
3, 14). When the operation of the touch switch is detected, touch position (reaction point) coordinates ( _Xo , _Yo ) are obtained, and a rectangular area ( _Xo ±) centered on the touch position coordinates is obtained.
a, _Yo ± b) are set (steps 15 to 17). Here, when the landmark coordinates are stored in the latitude and longitude coordinate system, the touch position coordinates are converted to the latitude and longitude coordinate system in the map. Then, to get the landmark in the rectangular area, if there is a landmark in the rectangular region, it calculates the coordinates difference between each landmark coordinates and the touch position coordinates obtained (X _n, Y _n), the coordinates The landmark with the smallest difference is selected, the selected landmark is displayed at the center of the screen, and the name of the selected landmark is displayed on the screen (steps 18 to 23). If there is no landmark in the rectangular area in step 19, the touch position is displayed at the center of the screen, and the process is terminated.

In FIG. 12, when the selected landmark is displayed at the center of the screen and the name of the selected landmark is displayed on the screen, if there is no other key input, the touch detection wait is awaited. If there is, a process corresponding to the key operation is executed, and the process ends (steps 25 to 27). When a touch is detected, the touch position coordinates (X _o ′, Y _o ′) are obtained, and it is determined whether or not a predetermined time has elapsed since the previous touch. The coordinate difference from the position coordinates is calculated, and if the coordinate difference is within a predetermined range, the coordinate difference (X _n , Y) between each acquired landmark coordinate and the touch position coordinate
_n ) is calculated, and a predetermined value is multiplied by the coordinate difference between the landmark coordinates and the touch position coordinates for the landmarks obtained up to the previous time (steps 28 to 33). Thus, the landmark with the smallest coordinate difference is selected (step 3).
4) The selected landmark is displayed at the center of the screen (step 35), the name of the selected landmark is displayed (step 36), and another key input is awaited. In the case of the land setting, the facility of the selected landmark is set as the destination. If the predetermined time has elapsed since the previous touch in step 29, the process shifts to landmark acquisition, selection and display processing again as another switch operation. In step 31, the coordinates of the previous touch position and the current touch position are displayed. If the coordinate difference from the coordinates is not within the predetermined range, the process shifts to landmark acquisition, selection, and display processing again as another switch operation.

In the flow in FIGS. 11 and 12,
The processing of step 29, or steps 30 and 31 is processing for determining whether or not the selection has been made again due to an erroneous touch in the present invention. The process of step 33 is the process of the present invention for lowering the selection probability of the landmark selected up to the previous time after the re-selection due to an erroneous touch. In the case of re-selection in the processing of step 33,
Although the distance is changed by multiplying the coordinate difference between the current touch position and the coordinates of the landmark selected up to the previous time by a predetermined value, the selection probability may be reduced by changing the predetermined value.

FIG. 13 is a diagram showing an example in which the selected landmark is displayed at the center of the screen and detailed information is displayed. In FIG. 13, when touching one of the densely displayed landmarks Y, the landmark Y is displayed at the center of the screen, and the cursor is superimposed on the landmark. The name of the facility, the business hours, the telephone number, and the presence of a parking lot are displayed. Also in this case, when a mark other than the target mark is touched, if the mark is pressed again within a predetermined time, marks next to the reaction point are sequentially selected.

FIG. 14 is a diagram showing an example of selection when the regulation marks are densely displayed. The screen of FIG. 14 is a screen in a case where other regulations in FIG. 5 are selected,
The construction mark and the lane regulation mark are partially overlapped and displayed. When a lane regulation mark is selected, the lane regulation mark is displayed at the center of the screen, a cursor is displayed over the lane regulation mark, and at the same time, the date and time of lane regulation and the details of the regulation are displayed as lane regulation information.

In the above embodiment, in a navigation device having a touch panel provided on a display screen, various information is displayed superimposed on a map, and the displayed information is used as a selection item. However, the present invention is not particularly limited to this. Instead, the present invention can be applied to all devices that display various information on a display device provided with a touch panel and use the displayed information as a touch selection item. However, this is suitable when the display screen is small, such as a vehicle display device.

FIG. 15 is a diagram showing another example of item selection in the peripheral search. In this example, the next candidate key is prepared, and if the target mark is not selected when the densely displayed landmark is selected, the next mark is not pressed again without pressing the landmark switch. When the candidate switch is operated, other landmarks are sequentially selected in ascending order of the coordinate difference, and a target landmark is set.

More specifically, after obtaining the coordinates of the touch reaction point (point O in FIG. 10), a predetermined area is set around the reaction point, and landmarks included in the predetermined area are obtained. May be obtained by calculating the coordinate difference between each landmark coordinate and the touch reaction point coordinate acquired in advance, and storing the table as a table in ascending order of the coordinate difference. In the above example, by operating the next candidate switch,
We selected landmarks stored sequentially,
When the predetermined area set at the time of the first touch is touched again, the next candidate may be sequentially selected with reference to the table.

[0038]

As described above, according to the present invention, when a selection item (mark) is displayed on the touch panel and the displayed portion is touched, the coordinates of the facility indicated by the selection item and the touch detection position are displayed on the map. Find the distance between the two from the coordinates of
Since the closest item is selected, even when the selection items are displayed densely, it is possible to select the optimum selection item for the touch position.

In particular, by displaying landmarks on a map,
By touching the landmark position to display information about the landmark or applying it to a map display device or a navigation device for setting points, the landmarks are dense when displaying an urban area or a wide area map. Also in this case, it is possible to select an optimum selection item for the touch position.

If it is determined that the selection item has been selected again due to an erroneous touch after selecting the selection item, the selection probability of the selection item selected last time is reduced. Misselection is less likely to occur, and operability can be improved.

In particular, by displaying landmarks on a map,
By applying to a map display device or a navigation device that displays information about a landmark or sets a point by touching the landmark position, the landmarks are crowded when displaying an urban area or a wide area map, and may be incorrect. If you make a selection and then select it again, it will be difficult to make a wrong selection again,
Operability is improved.
