In the area specifying mode, a track based on the change of the finger position is calculated, and a closed region formed of the track is specified as the area.

Description

  The present invention relates to a map display device provided with a touch panel.

  Many map display devices are equipped with a touch panel that enables an input operation by touching a display screen. When a touch panel is used, an intuitive input operation is possible, which contributes to improvement of user operability.

  In recent years, there has been proposed an apparatus that can specify a desired area on a map by touching the area on the map displayed on the display screen using such a touch panel (for example, Patent Document 1). In this apparatus, facilities can be searched in an area designated on the map.

JP 2010-19573 A

By the way, in a map display device, it is common that a map scroll is performed by touching a display screen.
However, in such a map display device having a map scroll function, if the display screen is touched to specify an area, the map scrolls against the user's intention. It is difficult to specify a desired area on the map.

  The present invention has been made to solve the above-described problems, and an object thereof is to realize map scrolling and area designation on a map by an easy operation in a map display device having a touch panel. .

  In the map display device according to the present invention, a touch state of a user's finger on a display screen capable of displaying a map is detected by a touch state detection unit. The proximity state of the user's finger to the display screen is detected by the proximity state detection means.

  Then, the map scroll mode is executed by the execution means. The map scroll mode is a mode in which, when a finger touch state is detected, the user's finger position in the touch state is acquired, and the map is scrolled based on the acquired finger position.

  Here, when the proximity state of the finger is detected, the area specifying mode is executed. The area specifying mode is a mode for acquiring the finger position of the user in the proximity state and specifying the area on the map based on the acquired finger position.

  That is, in the map display device according to the present invention, the proximity state of the finger is detected separately from the touch state of the finger, and the area specifying mode is executed. In this way, an area can be designated in a proximity state different from the touch state. As a result, in a map display device equipped with a touch panel, map scrolling and area designation on the map can be realized by an easy operation.

  By the way, regarding the start timing of the area specifying mode, for example, when the proximity state detecting unit detects the proximity state of the user's finger to the display screen for a predetermined time or more, the area specifying mode may be executed. In this way, the short-term proximity state that happens to point on the map is removed, and the area specifying mode is executed at an appropriate timing.

  As for the start timing of the area specifying mode, for example, when the proximity state detecting unit detects the proximity state of the user's finger to the display screen, It is conceivable to execute a specific mode. Also in this case, the short-term proximity state that happens to point on the map is removed, and the area specifying mode is executed at an appropriate timing.

  On the other hand, with regard to the end timing of the area identification mode, for example, when an area on the map is identified in the area identification mode, execution of the area identification mode is stopped and the map scroll mode is executed. In this way, after the area is specified, the map can be automatically scrolled, and the user does not have to instruct to end the area specifying mode.

  As for the end timing of the area identification mode, for example, when the touch state detection unit detects the touch state of the user's finger on the display screen in the area identification mode, the execution of the area identification mode is stopped, and the map It is conceivable to execute the scroll mode. If it does in this way, area specific mode can be ended by a user's intention.

  Regarding area identification, in the area identification mode, when the finger position trajectory based on the acquired finger position change forms a closed area on the map, the closed area may be identified as an area on the map. Illustrated. If the “closed region” is, for example, a circular locus, it is an area inside the circular locus.

  However, when an area on the map is enclosed in the proximity state, there is a possibility that the closed area is not formed because the start point and the end point are shifted. Therefore, when it can be inferred from the locus of the finger position that the user is going to surround the area, the area may be regarded as a closed area. For example, the same region may be surrounded by fingers, such as double or triple. Specifically, it is conceivable to partially compare trajectories that are double and triple and determine whether or not the portions have an approximation degree within a predetermined threshold. In this case, even if the area surrounded by the trajectory is not a closed area, the area is identified as a closed area. This makes it easy to specify the area.

  From the viewpoint of facilitating the designation of the area, the locus of the finger position may be displayed on the map. That is, the execution means may display a finger position locus based on the obtained finger position change on the map in the area specifying mode. In this way, since the locus of the finger position is displayed on the map, the user can confirm the area to be specified, and the area can be specified reliably.

  By the way, the specified area is considered to be an area of interest of the user. Therefore, the specified area is displayed on the map in an identifiable manner, and when the touch state of the user's finger to the specified area is detected by the touch state detecting means, the specified area is enlarged and displayed. You may make it do. Here, “display in an identifiable manner” is exemplified by displaying the boundary line of the area or displaying the inside of the area in a color different from the outside. In this way, the designated area can be enlarged and displayed by an easy operation.

  Further, the specified area may be displayed on the map so as to be identifiable, and information on facilities satisfying a predetermined condition among the facilities located in the specified area may be displayed. In this way, facility search can be performed with an easy operation.

  The above has been described as the invention of the map display device, but can also be realized as an invention of a program. That is, it is a program that causes a computer to function as execution means of the map display device. By executing such a program, the same effect as the map display device can be obtained.

Hereinafter, a navigation device as an embodiment will be described with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of the navigation apparatus. The navigation device is mainly configured by the control unit 10, and the control unit 10 includes an input unit 20, a map data storage unit 30, a current position calculation unit 40, a communication unit 50, a speaker 60, and a drawing unit 70. Is connected. A display 71 is connected to the drawing unit 70.

  The control unit 10 is configured as a normal computer. The control unit 10 includes a CPU, a ROM, an I / O, a bus line that connects these components, and the like. The control unit 10 controls the entire navigation device.

  The input unit 20 includes a proximity sensor 21 and a touch panel 22. The input unit 20 is used to give instructions to the system, and both are input on the display screen. In the proximity state via the proximity sensor 21 and in the touch state via the touch panel 22. Input is possible.

  The proximity sensor 21 is composed of, for example, a low power consumption distance measuring sensor. The proximity sensor 21 is attached to, for example, the top and bottom or the left and right of the display 71, and detects the user's finger position when approaching the display screen of the display 71 by transmitting and receiving light or radio waves. The touch panel 22 is integrated with the display screen of the display 71 and detects the finger position of the user when touching the display screen of the display 71.

  The map data storage unit 30 is a storage device realized as, for example, a hard disk device (HDD). Although the HDD is used in the present embodiment, other media such as a DVD-ROM and a memory card may be used. The map data storage unit 30 stores so-called map matching data for improving the accuracy of position detection and map data for searching for a route.

  The map data includes facility information regarding the facility. Specifically, POI (Point Of Interest) information stored in association with an ID for specifying a facility is stored. The POI information includes facility ID, address, data indicating type (genre), and the like.

  The current position calculation unit 40 calculates the current position of the vehicle. For example, a geomagnetic sensor, a gyroscope, a distance sensor, and a GPS (Global Positioning System) receiver that receives radio waves from a satellite are included. Since these have errors of different properties, they are used while complementing each other.

  The communication unit 50 is configured to perform information communication with the outside. Various information is acquired from the center apparatus by communicating with an external center apparatus (not shown). The speaker 60 outputs sound, and is used, for example, when performing route guidance by sound.

  A display 71 is connected to the drawing unit 70. The display 71 is a color display device configured using liquid crystal or the like. With this configuration, the control unit 10 displays a map and information on the display 71 via the drawing unit 70.

  Under such a configuration, the control unit 10 executes the map scroll mode. In the map scroll mode, when the touch state of the user's finger on the display screen of the display 71 is detected on the touch panel 22, the finger position of the user in the touch state is acquired and based on the acquired finger position. To scroll the map. Next, map scroll processing will be described.

FIG. 2 is a flowchart showing map scroll processing. This map scroll process is repeatedly executed while the map scroll mode is being executed.
In first S100, it is determined whether or not the touch state of the user's finger on the display screen is detected. This process is a determination process based on a signal from the touch panel 22. If it is determined that a touch state has been detected (S100: YES), the process proceeds to S110. On the other hand, when it is determined that the touch state has not been detected (S100: NO), the map scroll process is terminated without executing the subsequent processes.

  In S110, the finger position is acquired. In this process, the finger position is acquired as a coordinate value on the display screen based on a signal from the touch panel 22. In subsequent S120, the map is scrolled so that the point corresponding to the finger position comes to the center of the display screen. After executing the process of S120, the map scroll process is terminated.

  In this embodiment, the map is scrolled by touching a point on the map. For example, the map is scrolled to follow the finger by a drag operation of sliding the finger on the display screen. It is good also as a structure. Further, the map may be scrolled at high speed by flicking the display screen with a finger.

  Here, particularly in the present embodiment, when the proximity state of the user's finger to the display screen is detected, the map scroll mode is shifted to the area specifying mode. Next, the area identification mode transition process will be described.

FIG. 3 is a flowchart showing the area identification mode transition process.
In first S200, it is determined whether or not the proximity state of the user's finger to the display screen is detected. This process is a determination process based on a signal from the proximity sensor 21. If it is determined that a proximity state has been detected (S200: YES), the process proceeds to S210. On the other hand, when it is determined that the proximity state has not been detected (S200: NO), the subsequent process is not executed and the area specifying mode transition process is terminated.

In S210, the finger position is acquired. In this process, the finger position is acquired as a coordinate value on the display screen based on a signal from the proximity sensor 21.
In subsequent S220, it is determined whether or not the finger position is stopped. Here, affirmative determination is made when there is no change in the finger position or when the finger position is minute. If it is determined that the finger position remains unchanged (S220: YES), the process proceeds to S230. On the other hand, when the finger position is moving (S220: NO), the processing from S200 is repeated.

  In the next S230, it is determined whether or not a predetermined time has elapsed. If it is determined that the predetermined time has elapsed (S230: YES), the process proceeds to S240, and the area specifying mode is executed. After the process of S240 ends, the area identification mode transition process ends. On the other hand, while the predetermined time has not elapsed (S230: NO), the processing from S200 is repeated.

  In FIG. 4, the display screen is indicated by the symbol G. Hereinafter, also in other drawings, it is described as “display screen G” as appropriate. In FIG. 4B, the finger position locus based on the finger position change is indicated by a two-dot chain line k.

  In the area specifying mode, the finger position of the user in the proximity state is acquired, and the area on the map can be specified based on the acquired finger position. Next, the area specifying process will be described.

FIG. 5 is a flowchart showing the area specifying process. This area specifying process is repeatedly executed in the area specifying mode.
In the first S300, the finger position in the proximity state is acquired. In this process, the finger position is acquired as a coordinate value on the display screen based on a signal from the proximity sensor 21 as in S210 in FIG.

  In subsequent S310, the finger position change is acquired. This process acquires the change based on the finger position repeatedly acquired in S300. In the next S320, the trajectory of the finger position on the display screen is calculated based on the obtained change in finger position.

  In subsequent S330, it is determined whether or not a closed region is formed. This process determines whether or not a closed area is formed on the display screen based on the locus calculated in S320. Specifically, as shown in FIG. 6A, when the trajectory of the finger position indicated by a two-dot chain line k intersects on the display screen G, a closed region (region indicated by symbol A) is located inside the trajectory. Is formed. If it is determined that a closed region has been formed (S330: YES), the process proceeds to S350. On the other hand, when it is determined that the closed region is not formed (S330: NO), the process proceeds to S340.

  In S340 which is shifted when it is determined that the closed region is not formed, it is determined whether or not a certain region is surrounded by a plurality of trajectories. Specifically, as shown in FIG. 6 (b), an affirmative determination is made when the region indicated by the symbol B is doubly surrounded by the trajectory of the finger position indicated by the two-dot chain line k. For example, the trajectories that are double and triple are partially compared, and it is determined whether or not the portions have an approximation degree within a predetermined threshold. If it is determined that the object is surrounded by a plurality of trajectories (S340: YES), the process proceeds to S350. On the other hand, when it is determined that it is not surrounded by a plurality of trajectories (S340: NO), the processing from S300 is repeated.

  In S350, an area is specified. This process specifies a region formed inside the finger position locus. In FIG. 6A, the closed region indicated by the symbol A is specified. On the other hand, in FIG. 6B, since the closed region is not formed, an appropriate closed region is formed by extending the first finger position (indicated by symbol S), for example. That is, an area surrounded by a finger position locus a plurality of times is regarded as a closed area.

  When the area is specified, in the next S360, a map scroll mode transition process is executed. Here, the details of the map scroll mode transition processing will be described based on the flowchart of FIG. In first S361, it is determined whether or not a touch state is detected. This process is the same process as S100 in FIG. 2, and is a determination process based on a signal from the touch panel 22. If it is determined that a touch state has been detected (S361: YES), the execution of the area specifying mode is stopped and the map scroll mode is executed in S362, and then the map scroll mode transition process is terminated. On the other hand, as long as the touch state is not detected (S361: NO), the subsequent process is not executed, and the map scroll mode transition process is terminated.

  The area specified by such area specifying processing is used as a search area for a facility that is a destination candidate such as destination setting, for example. For example, information on the specified area is passed to the search process, and facility information in the area is searched.

  As described above in detail, in the present embodiment, when the proximity state of the user's finger is detected in the map scroll mode (S200: YES in FIG. 3), the process proceeds to the area specifying mode. In this area specifying mode, a finger position on the display screen is acquired (S300 in FIG. 5), a trajectory based on a change in finger position is calculated (S310, S320), and the formed closed region is specified as an area. (S330: YES, S350).

  That is, the proximity state of the finger is detected separately from the touch state of the finger, and the area specifying mode is executed instead of the map scroll mode. Thereby, an area can be designated in a proximity state different from the touch state. As a result, in a map display device equipped with a touch panel, map scrolling and area designation on the map can be realized by an easy operation.

  In this embodiment, when the user does not move the finger for a predetermined time with the finger placed close to the display screen (S210, S220: YES in FIG. 3), the area specifying mode is executed (S230). . Thereby, the short-term proximity state that happens to point on the map is removed, and the area specifying mode is executed at an appropriate timing.

  Furthermore, in this embodiment, after the area is specified, when the touch state of the user's finger on the display screen is detected (S361: YES in FIG. 7), the execution of the area specifying mode is stopped. The map scroll mode is executed. Thereby, the area specifying mode can be ended easily and easily by the user's intention.

  In the present embodiment, the locus of the finger position in the proximity state is calculated (S320 in FIG. 5), and when the closed region is formed by this locus (S330: YES), the closed region is specified as the area. (S350). However, when an area on the map is enclosed in the proximity state, there is a possibility that the closed area is not formed because the start point and the end point are shifted. Therefore, even if a closed region is not formed (S330 in FIG. 3: NO), if a certain region is surrounded by a plurality of loci (S340: YES), specifically, double or triple The trajectories thus obtained are partially compared, and when the portions have an approximation within a predetermined threshold, the region is regarded as a closed region and the area is specified (S350). This makes it easy for the user to specify the area.

  The display 71 in this embodiment corresponds to “display means”, the touch panel 22 corresponds to “touch state detection means”, the proximity sensor 21 corresponds to “proximity state detection means”, and the control unit 10 executes “execution”. It corresponds to “means”.

As mentioned above, this invention is not limited to the said embodiment at all, and can be implemented with a various form, unless it deviates from the range of the technical idea.
(A) Various processes for the specified area may be possible. Specifically, instead of the map scroll mode transition process of S360 in FIG. 5, for example, an area display process shown in FIG. 8 may be executed.

  In the first S400, the specified area is displayed. This process displays the specified area in an identifiable manner. For example, the boundary line of the area is displayed, or the color in the area is displayed in a color different from the background color.

  In next step S410, it is determined whether or not the touch state of the user's finger on the display screen is detected. If it is determined that a touch state has been detected (S410: YES), the process proceeds to S420. On the other hand, while the touch state is not detected (S410: NO), the subsequent processing is not executed and the area display processing is terminated.

  In S420, it is determined whether or not the inside of the area has been touched. If it is determined that the touch is in the area (S420: YES), the area map is enlarged and displayed in S430, and then the area display process is terminated. On the other hand, when it is determined that the touch is outside the area (S420: NO), the execution of the area specifying mode is stopped and the map scroll mode is executed in S440, and then the area display process is ended. In addition, after the area is enlarged and displayed in S430, the area specifying process may be further performed for the inside of the enlarged and displayed area without ending the area display process.

  In this way, the map of the designated area can be enlarged and displayed with an easy operation. In the above-described embodiment, the specified area is passed to the search process. However, at this area display stage, information on facilities that satisfy a predetermined condition among the facilities located in the specified area is displayed. You may make it do. As an example of the predetermined condition, there is information on a facility to be displayed when an area is designated, for example, information on a genre of a facility such as a convenience store or a gas station. Such a predetermined condition may be registered in advance in the map display device by the user, and when the area is designated, the user may select the genre of the facility to be displayed each time. Also good. In this way, facility search can be performed with an easy operation.

(B) In the above embodiment, as shown in FIG. 4A, the transition timing to the area specifying mode is determined based on whether or not a predetermined time has passed without changing the finger position in the proximity state. (S220, S230 in FIG. 3), as shown in FIG. 4 (b) as a modification, even if the finger position changes while maintaining the proximity state, You may comprise so that area specific mode may be performed.
In this case, the processing of S210 and S220 in FIG. 3 may be omitted, and only a lapse of a predetermined time may be determined in S230.
In other words, in this configuration, the case where the finger position is changed while the proximity state is maintained is determined after a predetermined time has elapsed.

Further, regarding the transition to the area identification mode, for example, instead of the area identification mode transition process shown in FIG. 3, an area identification mode transition process as shown in FIG. 9 may be executed.
First, similarly to S200 and S210 in FIG. 3, when the proximity state is detected, the finger position is detected (S500, S510). At this time, a change in the finger position is acquired (S520), and when the finger position changes by a predetermined distance or more while the proximity state is maintained (S530: YES), the area specifying mode is executed (S550).
That is, in this configuration, when the finger position changes while maintaining the proximity state, the determination is made based on the distance of the finger position change.

  In any of the above-described modified examples, if the finger position is changed in the proximity state, the area specifying mode is entered. Therefore, there is an effect that it is not necessary to wait for a predetermined time while the finger is held at a fixed position.

  Note that, when the change of the finger position at a predetermined distance is determined as in the latter case, a part of the area specifying operation can be a condition for shifting to the area specifying mode. In this case, if the change of the finger position is stored (S540) and the change of the finger position before the mode transition is read in the area specifying process (see FIG. 5), the area is easily surrounded with the fingers. Since the area specifying mode is executed by the operation, it contributes to easy area designation on the map display screen.

  (C) In the above embodiment, the finger position is acquired (S300 in FIG. 5), and the trajectory of the finger position based on the change of the finger position is calculated (S310, S320). Here, the calculated locus of the finger position may be displayed on the display screen. In this way, the area surrounded by the finger becomes clear at a glance, so that the user can easily specify the area.

(D) In the above embodiment, as shown in FIG. 5, the finger position is acquired (S300), the change of the finger position is acquired (S310), the trajectory of the finger position is calculated (S320), and the area is It was specified (S350).
On the other hand, it is good also as a structure which acquires only a finger position and specifies an area based on this finger position. Specifically, when the finger position is acquired, an area within a predetermined range from the finger position (for example, a circular area having a radius of 5 km) is specified as an area, an administrative division including the finger position is specified as an area, It may be configured to detect a road in the vicinity of the position and specify an area along the road, for example, an area having a width of 100 m or less as an area. In this case, the display screen can be simply operated with a simple finger. It becomes possible to specify a user desired area.

  (E) In the above embodiment, the present invention is realized in the form of a navigation device. However, any device including a map display device may be used, and for example, it may be realized as a mobile terminal capable of displaying a map.
