BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of a display control device, a display control method, a display control program, and a recording medium according to the present invention will be described in detail with reference to the accompanying drawings.

[0015] (Embodiment)

First, the functional configuration of the display control apparatus 100 that is relevant to the embodiment will be described. FIG. 1 is a block diagram showing a functional configuration of the display control apparatus. The display control device 100 includes a control unit 101, a determination unit 102, and an input unit 103, and controls display of map information on the display unit 110.

Note that each functional unit of the display control apparatus 100 described above is integrated with the display control apparatus 100. However, the present invention is not limited to this, and a plurality of devices may be connected. When each functional unit is connected as a different device, the connection between the devices may be established by performing communication using Bluetooth (registered trademark) or the like, regardless of wired or wireless.

The control unit 101 changes the display of map information on the display unit 110 along a predetermined route. The predetermined route is, for example, a route connecting a starting point and a destination point designated by the user. Further, for example, a route including a point designated by the user or a point within a predetermined distance of the feature force may be used. Further, there may be a plurality of predetermined routes.

[0018] Note that the map information displayed on the display unit 110 by the control unit 101 may include a part of the route or may include the entire route. When displaying the map information including a part of the route, the control unit 101 displays, for example, the map information within the predetermined distance of the road force that is the route along the route. Further, when displaying map information including the entire route, the control unit 101 moves, for example, a moving body display indicating a moving body moving along the route along the route on the map information.

[0019] The determination unit 102 determines whether or not there is a predetermined point on the route. The predetermined point is, for example, a point where a predetermined feature is located. Predetermined features include, for example, features specified by the user, features that appear fewer on the route than other features, features that are important in traffic regulations, and points near the right or left turn point. Some features. In addition, when the display control apparatus 100 includes an output unit that outputs guidance information on a route, this is a point where guidance information is output by the output unit. For example, the determination unit 102 determines whether or not there is a feature for each predetermined section on the route.

The input unit 103 receives an instruction input for displaying map information. The input unit 103 is, for example, an input device having a plurality of keys, and instruction contents are assigned to each key. The contents of the instruction include, for example, acceleration / deceleration of map information change, pause, and termination.

The control unit 101 changes the change mode of the map information based on the determination result of the determination unit 102 or based on the instruction input input to the input unit 103. For example, the control unit 101 displays the map information of the section determined by the determination unit 102 that there is no predetermined point. The interval is made shorter than the display time of the map information in the section where it is determined that there is a predetermined point. Also

For example, when there is an instruction input for instructing the acceleration of the change in the map information to the input unit 103, the control unit 101 accelerates the change in the map information.

Next, the procedure of display control processing by the display control apparatus 100 will be described. FIG. 2 is a flowchart showing a procedure of display control processing by the display control device. In the flowchart of FIG. 2, a case where the control unit 101 changes the change mode of the map information based on the determination result of the determination unit 102 will be described. The display control apparatus 100 causes the control unit 101 to change the display of the map information on the display unit 110 along a predetermined route (step S201).

Next, the determination unit 102 determines whether or not there is a force at a predetermined point in a predetermined section on the route (step S202). When there is a predetermined point (step S202: Yes), the control unit 101 causes the display unit 110 to display the map information of the section for a predetermined time (standard time) (step S203). On the other hand, when there is no predetermined point (step S202: No), the control unit 101 causes the display unit 110 to display the map information of the section for a time shorter than the standard time (step S204).

[0024] Until the display of the map information on the display unit 110 reaches the end point of the route (step S205: No), the process returns to step S201 and the subsequent processing is repeated. When the display of the map information on the display unit 110 is the end point of the route (step S205: Yes), the processing according to this flowchart is terminated.

[0025] As described above, according to the display control device 100, when the display of the map information on the display unit 110 is changed along a predetermined route, it is determined whether or not the force on the route includes a predetermined point. Therefore, the display mode of map information is changed. As a result, the display of the map information does not become monotonous, and the user's attention to the map information can be maintained.

[0026] For example, given a point where a feature that is a landmark on the route is located as a predetermined point, the display time of the map information of the section in which the feature is determined to be located will be displayed. If it is shorter than the display time of the map information of the section determined to be, the landmark feature on the route is displayed for a long time, making it easier for the user to understand the characteristics of the route. [0027] In addition, when a predetermined point is in the vicinity, detailed information of the point is displayed together with the map information, so that the user can be informed of the highlights on the route and miss the highlights when actually driving the route. Can be prevented. In addition, users' knowledge about routes and features can improve their interest.

[0028] Further, by changing the map information change mode based on the user's instruction input, the ratio of the portions that are less interesting to the user is reduced, and the mode is more suitable for each user. Map information can be displayed.

Example

Next, an example of the display control device 100 that works on the above-described embodiment will be described. In the following examples, the display control device 100 which is effective in the embodiment is displayed on the screen of the navigation device 300 mounted on the vehicle, more specifically, when the demonstration travel function of the navigation device 300 is executed. Explain the case of applying to screen display

[0030] (Hardware configuration of navigation device 300)

Next, the hardware configuration of the navigation device 300 will be described. FIG. 3 is a block diagram showing the hardware configuration of the navigation device. In FIG. 3, the navigation device 300 includes a CPU 301, a ROM 302, a RAM (memory) 303, a magnetic disk drive 304, a magnetic disk 305, an optical disk drive 306, an optical disk 307, and an audio IZF (interface) 308. A microphone 309, a speaker 310, an input device 311, a video IZF 312, a camera 313, a display 314, a communication IZF 315, a GPS unit 316, and various sensors 317. Each component 301 to 317 is connected by a bus 320.

First, the CPU 301 governs overall control of the navigation device 300. The ROM 302 records programs such as a boot program, a route search program, and an image display program. The RAM 303 is used as a work area for the CPU 301.

The magnetic disk drive 304 controls reading and writing of data to the magnetic disk 305 according to the control of the CPU 301. The magnetic disk 305 records data written under the control of the magnetic disk drive 304. As the magnetic disk 305, for example, HD (node disk) and FD (flexible disk) can be used.

The optical disc drive 306 controls reading and writing of data to the optical disc 307 according to the control of the CPU 301. The optical disc 307 is a detachable recording medium from which data is read according to the control of the optical disc drive 306. The optical disk 307 can also use a writable recording medium. Further, the removable recording medium may be a power MO of the optical disc 307, a memory card, or the like.

Another example of information recorded on the magnetic disk 305 and the optical disk 307 is map information used for route search / route guidance. The map information includes background data that represents features (features) such as buildings, rivers, and the ground surface, and road shape data that represents the shape of the road. Draw in the dimension. When the navigation device 300 is guiding a route, the map information and the current location of the vehicle acquired by the GPS unit 316 described later are displayed in an overlapping manner.

In this embodiment, the map information is recorded on the magnetic disk 305 and the optical disk 307. However, the present invention is not limited to this. The map information may be provided outside the navigation device 300, not the information recorded only in the one integrated with the navigation device 300 hardware. In that case, the navigation device 300 acquires the map information via the communication network through the communication IZF 315, for example. The acquired map information is stored in the RAM 303 or the like.

The audio IZF 308 is connected to a microphone 309 for audio input and a speaker 310 for audio output. The voice received by the microphone 309 is AZD converted in the voice IZF308. In addition, sound is output from the speaker 310. Note that the sound input from the microphone 309 can be recorded on the magnetic disk 305 or the optical disk 307 as sound data.

[0037] Examples of the input device 311 include a remote controller, a keyboard, a mouse, and a touch panel, each having a plurality of keys for inputting characters, numerical values, various instructions, and the like. Another information terminal device (such as a digital camera or a mobile phone terminal) connected to the navigation device 300 may be used as the input device 311.

The video IZF 312 is connected to a video input camera 313 and a video output display 314. The video IZF312 specifically controls the entire display 314, for example. Control that controls the display of the display 314 based on the graphic controller that performs image processing, a buffer memory such as VRAM (Video RAM) that temporarily records image information that can be displayed immediately, and image data that is output from the graphic controller Consists of IC and so on.

[0039] The camera 313 takes images inside and outside the vehicle and outputs them as image data. An image taken by the camera 313 can be recorded on the magnetic disk 305 or the optical disk 307 as image data. The display 314 displays icons, cursors, menus, windows, or various data such as characters and images. As this display 314, for example, a CRT, a TFT liquid crystal display, a plasma display or the like can be adopted.

[0040] Communication IZF 315 is connected to a communication network such as the Internet via radio, and functions as an interface between this communication network and CPU 301. Examples of communication networks include public line networks, mobile phone networks, LANs, and WANs.

[0041] The GPS unit 316 receives radio waves from GPS satellites and outputs information indicating the current position of the vehicle (current position of the navigation device 300). The output information of the GPS unit 316 is used when the CPU 301 calculates the current position of the vehicle together with output values of various sensors 317 described later. The information indicating the current location is information that identifies one point on the map information, such as latitude'longitude and altitude.

The various sensors 317 output information that can determine the position and behavior of the vehicle, such as a vehicle speed sensor, an acceleration sensor, and an angular velocity sensor. The output values of the various sensors 317 are used for calculation of the current position by the CCU 301 and measurement of changes in speed and direction.

In the configuration of the display control apparatus 100 shown in FIG. 1, the control unit 101 and the determination unit 102 realize the respective functions by the CPU 301, and the input unit 103 by the input device 311. The display unit 110 corresponds to the display 314.

[0044] (Demo driving process by the navigation device 300)

Next, the demonstration traveling process by the navigation device 300 will be described. The navigation device 300 has a demonstration travel function that moves a display indicating the vehicle position along a route searched by the route search function and scrolls the map information. Running By executing the demo driving function before the start, the user can image the current drive flow and operate smoothly.

FIG. 4 is a flowchart showing the procedure of the demonstration travel process by the navigation device. In the flowchart of FIG. 4, the navigation device 300 first receives an input of a departure point and a destination point selected by the user (step S401). The starting point and destination point are input by specifying an arbitrary position on the map information displayed on the display 314, or by inputting the address and latitude / longitude of the point.

Next, navigation device 300 searches for a route connecting the input departure point and destination point (step S402). There may be one or more routes searched for at this time. The route search may be performed in consideration of priorities specified by the user such as a fee and distance. Further, the navigation device 300 presents the searched route to the user.

Subsequently, navigation device 300 waits until one route is selected from the routes searched in step S402 by the user (step S403: loop of No). When the route is selected (step S403: Yes), the navigation apparatus 300 determines whether or not the selected route is to be demo-run (step S404). The determination as to whether or not to perform a demo run is made, for example, based on whether or not an instruction input for instructing the demo run has been received within a predetermined time.

[0048] When performing the demo travel (step S404: Yes), the navigation apparatus 300 sets a skip point on the route for the demo travel (step S405). A skip point is a point that divides a route at predetermined intervals. For example, the skip point is set at a certain distance or set at a point where a certain traveling time is expected. A point arbitrarily designated by the user may be set as the skip point.

[0049] It should be noted that the point force to be set as a skip point in step S405 The point where guidance is made on the route (guidance point), the point where guidance announcements such as turning left and right are made (guidance point), and road type change For example, if the skip point is a point where the specified feature is located, the position of the skip point is shifted by a predetermined distance such as the position of the guide point so that the skip point and the guide point do not overlap. May be. This Here, the predetermined feature is, for example, a feature specified by the user, a feature having a smaller number of appearances on the route than other features, a feature important in traffic regulations, or a right / left turn point. This is a nearby feature.

[0050] When the skip point is set in step S405, navigation device 300 starts a demonstration run (step S406). During the demonstration run, you may display map information at a reduced scale that includes the entire route, or display map information at a reduced scale that does not include the force of the route, but allows you to understand the surrounding situation in detail. May be. Further, the point where the demonstration run is started is not limited to the departure point, and may be a point designated by the user.

[0051] When there is an input to the operation key of the input device 311 during the demonstration run (step S407: Yes), the navigation device 300 performs a process corresponding to the operation key (step S408). For example, when the input operation key is the “fast forward” key (step S41), the processing corresponding to the operation key is closest to the current vehicle position display in the traveling direction side, and the skip point (next The vehicle position is moved to the skip point (step S42), and the process proceeds to step S414. Also, for example, if the input operation key is the “rewind” key (step S43), the nearest skip point (previous skip point) to the current vehicle position display on the opposite side of the traveling direction The vehicle position is moved to (Step S44), and the process proceeds to Step S414.

For example, when the input operation key is a “pause” key (step S45), the movement of the vehicle position display is stopped (step S46), and the process proceeds to step S414. For example, when the input operation key is the “play” key (step S47), the vehicle position display is moved at the normal speed (step S48), and the process proceeds to step S414. Further, when the input operation key is the “stop” key (step S49), the demonstration traveling is terminated and the processing according to this flowchart is terminated.

[0053] As described above, the demonstration traveling is performed in response to the user's instruction input, so that it is possible to provide a demonstration traveling function that is easier for the user to use. For example, it is possible to perform a demo run adapted to each user's needs, such as fast-forwarding a part that does not require a demo, or repeatedly demoting a part where you want to check the directions well.

[0054] On the other hand, when there is no input to the operation key in step S407 (step S407: No), navigation is performed. The gating device 300 determines whether or not there is a guidance point and a predetermined feature (hereinafter referred to as “guidance point”) between the current vehicle position display and the next skip point. (Step S409). As described above, the predetermined feature is, for example, a feature specified by the user, a feature having a smaller number of appearances on the route than other features, a feature important in traffic regulations, These are features near the left turn point. If there is a guidance point (step S409: Yes), the vehicle position display is moved at a normal speed (step S410). Until the point in the plan is reached (step S411: No), return to step S410 and move at normal speed. When the guidance point is reached (step S411: Yes), guidance display, guidance announcement, etc. are performed (step S412), and the process proceeds to step S414.

[0055] If there is no guidance point or the like in step S409 (step S409: No), navigation device 300 moves the vehicle position display to the next skip point at high speed (step S413). As a result, the display time of each section can be changed according to the importance on the route. The section moved at high speed may be, for example, an expressway section or a section included in an area set by the user, in addition to a section without guide points.

Navigation device 300 returns to step S407 and repeats the subsequent processing until it reaches the destination point (step S414: No). When the destination point is reached (step S4 14: Yes), the processing according to this flowchart is terminated. In addition, when the demonstration run is not performed in step S404 (step S404: No), the process according to this flowchart is terminated, and for example, the process proceeds to an actual route guidance process.

[0057] Note that a plurality of routes may be selected in step S403. FIGS. 5 to 7 are diagrams showing examples of screen displays when a plurality of routes are demo run simultaneously. As shown in FIG. 5, when a plurality of routes are searched by route search, the navigation device 300 displays on the display 314 map information on a scale that can display all the searched routes (screen display 500). Screen display 500 shows route A and route B. The user can also select one of the routes to perform a demo run. [0058] When the demonstration driving is instructed while the route is not selected, the demonstration driving is simultaneously performed on the plurality of displayed routes. In this case, for example, as shown in FIG. 6, the vehicle position display is moved along each route (screen display 600). At this time, the moving speed of the vehicle position display is set to a speed proportional to the time taken when actually driving on the route. This allows the user to know how much time will be spent when using each route (which route will arrive the earliest), and when selecting a route to actually travel Can be helpful. For example, as shown in Fig. 7, it is possible to list the routes in the order of arrival time so that the route actually traveled can be selected (screen display 700).

[0059] In addition, for example, the user desires detailed information and receives designation of a facility such as a restaurant or a sightseeing spot from the user, and the information on the designated facility may be displayed during the demonstration run. Good. FIG. 8 is a diagram showing an example of a display screen when facility information is displayed during the demonstration run. In the display screen 800 of FIG. 8, in addition to the map information 801 including the current vehicle position display and the facility positions (A to C), an image image 802 of the facility and text information 803 regarding the facility are displayed. This makes it possible to organize the highlights of the travel route before actually traveling the route and prevent oversight of tourist spots.

[0060] Similarly, for example, when guiding a sightseeing spot in a certain area, if a representative route is introduced using the demonstration travel function, more realistic sightseeing guidance can be provided. For example, you may enjoy a simulated drive by demonstrating places that you cannot actually go to, such as foreign countries and remote areas.

In this embodiment, the navigation apparatus 300 mounted on the vehicle has been described as an example. However, for example, a mobile phone, a PDA, a PC, a portable game machine, etc. may be provided with a demonstration running function. .

[0062] As described above, according to the navigation device 300, when displaying the map information along the route by the demonstration traveling function, whether or not there is a guidance point or the like within a predetermined section on the route. To change the display speed of the vehicle position display in the section. As a result, the demo screen does not become monotonous and the user's attention to the demo run can be maintained. In addition, a point on the route is displayed for a long time, and features of the route to the user Can be made easier to understand.

[0063] Further, when a facility designated by the user is in the vicinity, detailed information on the facility is displayed together with the map information to inform the user of the highlights on the route, and when actually traveling on the route It is possible to prevent the point of interest from being overlooked. In addition, the user's knowledge and interest regarding the route itself and surrounding facilities can be improved.

[0064] Further, the ability to operate the demo run based on the user's instruction input reduces the proportion of the user's interests and places displayed, and the demo is adapted to each user. The driving can be displayed.

It should be noted that the display control method described in the present embodiment can be realized by executing a prepared program on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed when the recording medium force is also read by the computer. The program may be a transmission medium that can be distributed through a network such as the Internet.
