Description

  The present invention relates to an information providing method for providing route guidance (road guidance) data, and in particular, is applied to a car navigation system (car navigation), a personal computer (PC), a personal digital assistant (PDA), a mobile phone, a PHS, and the like. The present invention relates to a technology that can be used to provide various route information and additional information such as route guidance, sightseeing guidance, delivery planning, travel planning, traffic control, scheduling, entertainment, and local government services via networks and electronic media.

  In conventional guidance information services, for example, when a place to be guided is designated, data relating to the place is often displayed in a list. In addition, since the presentation contents are only information about the place (point, route, facility, etc.), it was not possible to flexibly guide the route to the place or a point in the middle.

  Furthermore, in the conventional guidance information service, since the service is provided in different formats for each system, it is difficult to mutually use the guidance information.

  Conventional guidance data includes static data such as maps, illustrations, and images, and voice guidance data in a car navigation system. These data have been built in the system in advance. For this reason, in the prior art, it has not been considered to reuse what has been created once or reuse it in various situations.

  In addition, most of the guidance data presentation methods only output each of them on demand, and even car navigation systems, etc., only provide guidance data when they come to a certain place. It was not like controlling the timing of presentation.

  Some systems for creating routes also exist in fields such as delivery planning, but the research and development is centered on the method of calculating the optimum route, taking into account the contents of guidance output to the user. There is nothing to do. Moreover, there was no system that automatically created it. Furthermore, there is no known method that considers even the distribution of these data in a form suitable for the network.

  Therefore, in order to solve the conventional problems, not only information on points, routes, facilities, etc., but also actual guidance or virtual guidance along the route to a certain place can be performed, and further, the movement of the place We have invented a guidance information presentation device, etc. as a means that can provide guidance in a format that can be used with various systems and devices, etc. 11-113191). Thus, for example, by specifying only the destination, guidance such as “This facility is famous for XX” can be presented along the route, and guidance data for that purpose can be created.

  The purpose of the present invention and the technology related to the present invention is to include a mixture of such guidances that are presented within a certain range and that are presented several minutes before reaching a certain point or area. To provide guidance data at an appropriate timing according to the situation, and to provide a method for efficiently processing the guidance data according to the user's request. Another object of the present invention is to provide a method for efficiently inputting guide data including information on points and routes in addition to automatically generating guide data with guide information and directly describing the data in a text format. In particular, an object of the present invention is to realize easy-to-understand presentation of guide routes in a map format and a tree format.

  In the present invention, the above problem is solved by the following method.

  The present invention uses both a method for presenting a guide route to a user in a map format and a method for presenting a guide route to a user in a tree format with at least a transit point and / or a guide point as a node. According to the instruction to be specified, the presentation in the map format and the tree format is moved to the point specified by the specified node. The instruction for specifying a node in the tree format may be an instruction by a user input or an instruction by execution of a guidance script. As a result, a specific waypoint or guide point can be selected from the presentation in the tree format, and the guide information of the position can be easily checked. In addition, it is possible to link map-type and tree-type presentations in simulation and actual navigation using a guidance script.

  In addition, the present invention presents the guide route to the user in a tree form that has at least a transit point or / and a guide point as a node and is hierarchized according to the level of detail. The part including the current position is displayed up to the lower hierarchy, and only the upper hierarchy is displayed for the part away from the current position. This makes it easy for the user to grasp the entire route on a display screen of a limited size and to obtain detailed information about the vicinity of the current location. At this time, in the text display, the character font of the corresponding content may be enlarged or the color may be changed with the movement so that the vicinity of the current point is displayed conspicuously.

  In addition, the technology related to the present invention is a guide script in which at least time information or / and place information and guide information to be output according to the time or / and place to be presented are described based on a predetermined specification. Operation information from a user regarding a guidance output method including at least one of reproduction, fast-forward, skip, and rewind in an apparatus having means for processing the time according to time and place and means for presenting guidance data to the user; , Based on the preset moving speed and / or time step information, the timing information of the time or / and location where the information is presented is generated, and written in the guidance script according to the generated timing information Guidance information matching the time information and / or location information is presented to the user.

  As a result, various types of simulations can be performed by generating the timing of the method of generating the time / location according to the operation information from the user as well as engraving the step of advancing the time / location at the time of the simulation of the guidance. Is possible.

  In addition, the technology related to the present invention provides guidance information that matches the time information and / or location information described in the guidance script based on the generated time / location timing information or the measured actual time / location. Is presented to the user, the guidance presentation start is instructed, the guidance information presentation period is managed in accordance with the guidance attribute information described in the guidance script, and the guidance presentation termination is instructed. As a result, appropriate guidance presentation time control can be realized by guidance attribute information described in the guidance script. After adjusting the presentation timing based on the guidance attribute information, for example, the presentation of time-consuming media such as audio and video, and static media such as images and text, separately from the guidance attribute information. Although it is possible to adjust the timing according to the media, the presentation timing is controlled by separating the presentation timing adjustment based on the attribute information and the presentation timing adjustment according to the output format (media) of the guidance. Can be facilitated.

  In addition, the technology related to the present invention provides guidance information that matches the time information and / or location information described in the guidance script based on the generated time / location timing information or the measured actual time / location. When the output time of a plurality of guidance information overlaps, the priority according to the type of guidance information or the priority according to the output medium is determined, and each guidance information is determined according to the priority determination result. Adjust the output timing. This makes it possible to give priority to more important waypoint guidance when, for example, route point guidance overlaps with general guidance point guidance.

  In addition, the technology related to the present invention confirms arrival at each waypoint or guide point obtained from the guidance script, predicts arrival time at each other waypoint or guide point based on this confirmation, Based on the estimated arrival time at each waypoint or guide point, schedule information relating to the presentation time of the guide information described in the guide script is generated, and the guide information is presented to the user based on the generated schedule information. In addition, the schedule information is corrected according to the arrival status at each waypoint or guide point. Thereby, for example, even when guidance information is presented to the user several minutes before arriving at a certain waypoint, guidance based on an accurate predicted time can be presented.

  In addition, the technology related to the present invention is specified when the number of times the guidance information to be output when it enters the specified area is specified in the guidance information described in the guidance script. Guidance information is output every time it enters the area, and 1 is subtracted from the number of times of output. When the number of times of output becomes 0, the output of the guidance information is suppressed even if it enters the specified area. As a result, even in the case of a route that frequently enters or leaves a certain area, it is possible to output guidance information for a predetermined number of times.

  In addition, the technology related to the present invention provides guidance information that matches the time information and / or location information described in the guidance script based on the generated time / location timing information or the measured actual time / location. Is presented to the user, and a predetermined advertisement, advertisement, or other general information is presented to the user at a gap time when there is no guidance information to be output. As a result, guidance information is output when necessary, and other information such as advertisements is output when the guidance information is unnecessary. Therefore, it is possible to expect free provision of guidance scripts by advertisers, etc. Script will be available for free.

  In addition, the technology related to the present invention provides guidance information that matches the time information and / or location information described in the guidance script based on the generated time / location timing information or the measured actual time / location. When the guidance information to be presented is three-dimensional content or video, the display mode of the three-dimensional content or the moving speed of the video is synchronized with the virtual or actual moving distance, and this synchronization control is performed. Based on the viewpoint of the display target. As a result, in accordance with actual progress, for example, display of 3D content or video display as seen from a car window becomes possible.

  In addition, the technology related to the present invention is such that when a reverse playback instruction is input from the user, left and right and front and rear in the guidance information by text or voice described in the guidance script are automatically left and right and front and rear, respectively. Convert to As a result, for example, when performing route guidance in the reverse direction from the destination to the departure point, it is possible to provide guidance without a sense of incongruity between front and rear and left and right.

  In addition, the technology related to the present invention presents the guide route based on the guide script to the user in a map format, and the route point and / or guide point in the guide route based on the guide script in the map format presentation is pinned. Display with type icon. When the plurality of pin-type icons overlap, the direction of the pin-type icon is changed so as not to overlap. This makes it possible to grasp at a glance the waypoints and guidance points related to the output of guidance information, and even when there are many waypoints and guidance points in a narrow area, one by one. Can be easily distinguished.

  In addition, the technology related to the present invention checks whether the guidance script is based on a predetermined specification, checks the feasibility or / and validity of the guidance script, and checks the result of the guidance script. Alternatively, an alternative based on the check result is output. By evaluating the feasibility and validity of the guidance script, it is possible to prevent in advance guidance that includes a lot of infeasible guidance and waste.

  Further, the technology related to the present invention presents the guide route related to the guide script being created to the user in a map format or a tree format, and a new waypoint or guide point is indicated in the map format or the tree format presentation. At that time, the via point or guide point is inserted at a position where the total distance of the guide route is shortened, and a guide script is created or edited based on the input via point or guide point information. As a result, it is possible to create a guidance script that can automatically circulate at the shortest distance even when a plurality of points to be routed are designated in a random order.

  In addition, the technology related to the present invention presents the guide route related to the guide script being created to the user in a map format or a tree format, and inputs an instruction of a waypoint or a guide point in the map format or the tree format presentation. Then, a guide route is determined based on the information of the route point or guide point that has been input, and at this time, guide information in a turning direction is automatically created based on the route calculation, and a guide script is generated based on the guide information. Create or edit. This makes it possible to create guidance scripts that can provide easy-to-understand route guidance by adding guidance points and guidance information that can be used as landmarks even when only the starting point and destination are entered, for example. become.

  In addition, the technology related to the present invention presents the guide route related to the guide script being created to the user in a map format or a tree format, and inputs an instruction of a waypoint or a guide point in the map format or the tree format presentation. Then, a guide route is determined based on the information on the route point or guide point that has been input, and for the intersections in the guide route, image templates to be output at the intersection are prepared by combining image templates of previously prepared intersections and arrows. Information is automatically created, and a guide script is created or edited based on the guide information. As a result, it is possible to easily create a guidance script that can provide route guidance with few errors at intersections without preparing images of all intersections.

  In addition, the technology related to the present invention interprets and executes a guidance script by a server device based on the position of a terminal that presents guidance information, and sends guidance information based on the execution result of the guidance script from the server device to the terminal. When identification information of a predetermined template is included in the transmitted guidance information, the guidance information is synthesized using a template corresponding to the identification information at the terminal and presented to the user. As a result, for example, even when a simple personal digital assistant (PDA) or the like is used, the amount of data transmitted from the server device to the terminal can be reduced and the transmission load can be reduced.

  In addition, the technology related to the present invention presents at least a module that generates a virtual time / place, a module that controls the timing of presenting guidance information based on a virtual or actual time / place, and the guidance information. A module that controls the presentation method of guidance information according to the user's terminal or output media information based on timing, a module that controls data communication, a module that controls the presentation of guidance data in a tree format, and guidance data in a map format A module for controlling the presentation of text, a module for controlling the presentation of data in text format, and a module for controlling dialogs for various types of guidance and settings are prepared as parts, and a plurality of these parts are prepared. By combining these parts, you can create a guidance script, a guidance script To create an application for the simulation by the line for, or guide for the script. This makes it possible to easily construct a system for creating and executing a guidance script.

  A program for realizing the above processes by a computer can be stored in an appropriate recording medium such as a portable medium memory, a semiconductor memory, or a hard disk that can be read by the computer.

  According to the present invention and the technology related to the present invention, it is possible to efficiently process the guidance data according to the user's request and present the guidance with an appropriate method and timing according to the situation. In addition, such guidance data can be easily created.

  For example, the following guidance can be executed and created.

・ Creation of albums for courses traveled ・ Explanation of invasions, battles and wars ・ Recommended information on amusement parks, museums and aquariums In particular, the present invention makes it possible to select a specific waypoint or guide point from the tree form and easily check the guide information of the position. In addition, it is possible to link map-type and tree-type presentations in simulation and actual navigation using a guidance script. In addition, on a display screen of a limited size, it becomes easy for the user to grasp the entire route, and detailed information about the vicinity of the current location can be obtained.

[Example of device configuration]
FIG. 1 is a block diagram showing a configuration example of the present embodiment. Based on the time / place generated by the time / place generation processing section 20 or the sensor 25, the information presentation timing control section 10 for controlling the timing of presenting the guidance data, and the time / place generation processing section for generating the time / place. 20, a sensor 25 that acquires the current time and current location, an information presentation method control unit 30 that controls a guidance presentation method according to a user's terminal, a data communication control unit 40 that controls data communication, and a guidance Guide data access unit 50 for controlling data access, tree format presentation control unit 61 for presenting guide data in a tree format, map format presentation control unit 62 for presenting guide data in a map format, guidance data, instructions, etc. A text format control unit 63 for controlling the presentation of the text format data, and various types A guidance dialog control unit 64 that controls a dialog for guidance and setting, a point / route database access unit 70 that controls access to a database of information on points and routes, and guidance data are created automatically or semi-automatically. An automatic guide creation processing unit 80 for editing and a guide data evaluation unit 90 for evaluating the created / edited guide data are provided.

  In this embodiment, a series of instructions of data of time, place, and guidance information recorded in various formats is described using a markup language description format. Instructions include time (for example, departure time, route time, arrival time, etc.), place (for example, departure point, waypoint, arrival point, etc.) and / or various media data (map, text, voice, music, images, A unit of a script including one shot of video etc. and partial data. For example, at a point A on a certain route, an instruction “outputs voice data (aaa.wav) and image data (xxx.jpg) explaining the point A when it is at the point A”) is an instruction. Hereinafter, a description language in this format will be referred to as NVML (NaVigation Markup Language).

  In the course of the guidance execution process, the guidance data (NVML data) described in the NVML is read into the user terminal from the network or various media by the guidance data access unit 50, and the virtual data issued from the time / place generation processing unit 20 is read. Based on the time / location or the actual time / location obtained from the sensor 25 such as GPS (Global Positionig System), the information presentation timing control unit 10 appropriately presents the guidance information suitable for the time / location. Control is performed so that the presentation is stopped at an appropriate timing.

  Based on this presentation start / stop signal, the information presentation method control unit 30 presents (displays) which information in what format in consideration of the processing capability of the terminal, the screen size, the user's request, and the like. And the guidance is provided through the tree format presentation control unit 61, the map format presentation control unit 62, the text format control unit 63, and the guidance dialog control unit 64, respectively.

  In the course of the guide creation process, depending on the user's preference, the tree format presentation control unit 61, the map format presentation control unit 62, the text format control unit 63, and the guidance dialog control unit 64 are used and added and edited one after another.

[Overview of NVML]
First, an outline of NVML used in the present embodiment will be described.

<nvml version = "0.60"> or something enclosed in <and>, such as <head> or </ head>, is called a tag. Tags that do not start with </ are called start tags, and tags that start with </ are called end tags. The start and end tags are
<title> NVML Ver.0.60 TestSample </ title>
Are used as a pair. This pair is called a tag set. Also,
<nvml version = "0.60">
Things like version in are called tag attributes, and things like 0.60 are called attribute values.

  In NVML, it is described by a hierarchical structure of a tag set that is a pair. If there is no tag set in the part sandwiched between the tag sets, that part is called the contents of the tag. The NVML script is configured using the tags, attributes, and contents as described above.

  For example, assume the following NVML script.

<body>
<navi>
<point>
<name> ○○ </ name>
</ point>
<info>
<text> △△ </ text>
</ info>
</ navi>
</ body>
This script means that “△△ route guidance information (text format) is output at the point of ○○”, and <point> and </ point> between <navi> and </ navi> The part enclosed by is the point, and the part enclosed by <info> and </ info> is the guidance information to be output.

  Also, assume that the following NVML script exists.

<body>
<guide>
<point area = "100m">
<name> ○○ </ name>
</ point>
<info>
<text> □□ </ text>
</ info>
</ guide>
</ body>
This script means "When you enter the range of 100m around the point of XX, output □□ guidance information (text format)", and between <guide> and </ guide> The part enclosed by <point area = "100m"> and </ point> represents the range, and the part enclosed by <info> and </ info> represents the guidance information to be output.

(1) Guide point (guide element)
The guide element is a child element of the body element. The guide element need not be described, and can be described any number of times. In the guide element, describe specific information about the guide for the location.

  A description example of the guide point is shown below.

<guide>
<point area = "1.0km">
<name> Kashiwa Park </ name>
<category> Park </ category>
<latitude> N35.37.30.200 </ latitude>
<longitude> E139.37.43.227 </ longitude>
<address> Tokyo, Setagaya-ku Yoga 2 </ address>
<zip-code> 158-0097 </ zip-code>
<phone> 01-2345-6789 </ phone>
</ point>
<info>
<text>
Hagi Park
</ text>
<voice>
Kashiwa Park was decided as a city plan as a commemorative project for 2600 AD
Its predecessor is a large green area.

</ voice>
<image src = "image / Kinuta-Park-01.jpg"/>
</ info>
</ guide>
This example shows the information described in the info element if it falls within the area where the point described in the point element is located (in this case, within a circle with a radius of 1.0 [km] centered on the point). Is output.

  By describing a guide element in NVML, at a certain time, or while the user is moving along a route specified by several navi elements, or simply not moving along a specific route Even in this case, the information described in the info element is output when entering the area of the point described in the guide element.

  Note that guide elements may be described between navi elements, and conversely, navi elements may be described between guide elements, or any combination thereof. In that case, the interpretation of the series of navi elements is exactly the same as that without all the guide elements.

(2) Via points (navi element)
The navi element is a child element of the body element. The navi element need not be described, and can be described any number of times. Describe specific information about route guidance in the navi element. The navi element has no attributes.

  The navi element has a point element, a route element, and an info element as child elements. One of the point element and route element must be described once. The info element need not be described, and can be described only once. The following child elements must be written in the order of point → info or route → info.

<navi>
<route>
<category> General roads </ category>
<means> car </ means>
</ route>
</ navi>
<navi>
<point>
<name> Nishi Ginza IC </ name>
<category> Metropolitan Expressway </ category>
<latitude> N35.40.19.960 </ latitude>
<longitude> E139.46.13.122 </ longitude>
<address> Chuo-ku, Tokyo </ address>
</ point>
<info>
<text> Enter the Metropolitan Expressway from Nishi Ginza Interchange. </ text>
<voice> Enter Metropolitan Expressway from Nishi Ginza Interchange. </ voice>
</ info>
</ navi>
This example means that the information described in the info element is output at the point described in the point element through the route described in the route element.

  By describing the navi element a plurality of times, it is possible to describe the guidance along the route passing through the point 1, the point 2,. The content of the route element does not necessarily describe the complete route from that point to the next point. If the route element is not described, or if the description is incomplete, the NVML system performs appropriate completion at the time of execution.

(3) Point information (point element)
The point element is a child element of the navi element and guide element. If it is a child element of navi element, one of point element and route element must be described once. If it is a child element of the guide element, the point element must be described once. The point element describes specific information about the point.

  In the NVML system, if a latitude element and a longitude element are described as child elements of the point element, first, the exact position of the point is specified using the information. If they are not described, specify them from the contents of other elements. If one point cannot be accurately identified due to insufficient description, the system will estimate the most appropriate point possible, select one specific point, and if that is not possible Is an error.

The area attribute can be described as an attribute only when the parent element is a guide element. The area attribute specifies the area of the point where the information described in the info element is output, with a radius centered on the point described in this point element. For example,
<point area = "1.0km">
Is described as follows.

(4) Route information (route element)
The route element is a child element of the navi element. The route element describes specific information about the route. The route element has no attributes.

(5) Guidance information (info element)
The info element is a child element of the head element, navi element, and guide element. The info element need not be described, and can be described only once. The info element describes specific information about the information to be output.

  When the parent element is a head element, it is left to the system when and where to output the information described in this info element. If the parent element is a navi element, information is output when the current location reaches the point described in the point element that is a sibling element. When the parent element is a guide element, the time and the time range described in the sibling element and the start time in the time range, or the range of points described in the sibling element point element Information is output when entering.

  Note that the output from the navi element may interfere with the output from the guide element. In such a case, whether to output both at the same time or whether to prioritize one over the other is left to the system based on prior setting information.

  A description example is shown below.

<info delay = "-5min" duration = "1min">
<text>
Yoga promenade
</ text>
<voice>
This is a promenade called Yoga Promenade.

            Let's walk a little to Sakai Park.

</ voice>
<image src = "image / Youga-Promenade-01.jpg"/>
</ info>
In this example, it is instructed to output guidance information by text, voice and image (image) for one minute five minutes before reaching a certain point, region or time.

  Next, attributes will be described. The info element has the following attributes:

(A) delay
Specify the start time when outputting information. The possible values of the attribute are as follows.

("+" ｜ "-")?
((0 | [1-9] [0-9] *) ("." [0-9] *)? "H")?
((0 | [1-9] [0-9] *) ("." [0-9] *)? "Min")?
((0 | [1-9] [0-9] *) ("." [0-9] *)? "S")?
If it is unsigned or “+”, it represents a delay from the start time (positive elapsed time), and “-” represents a progress from the start time (negative elapsed time). The start time is as follows.
-If the parent element is the head element, it is left to the system.
-When the parent element is a navi element The time at which a point described in the point element that is a sibling element arrives.
-When the parent element is a guide element-When the sibling element has a time element and there is no point element
The first time in the time range described in the time element. In addition, the number of times specified by the times attribute may be reset to any time (s) within that time range.
..If the sibling element has no time element and has a point element
The time at which the area described in the area attribute of the point element was entered. Reset each time you enter the area.
..When sibling element has time element and point element
The time that entered the area described in the area attribute of the point element within the time range described in the time element. Reset each time you enter the area.

  There is no default value. Setting the value when not specified is left to the system.

  The following example means that “when a point (Point No. 12) arrives within a radius of 1 km, the guidance information (GuideSample No. 12) in text and voice format is output 0.1 hour after the arrival time”.

<guide>
<point area = "1km">
<name> PointNo.12 </ name>
<latitude> N035.03.10.0 </ latitude>
<longitude> E140.03.10.0 </ longitude>
</ point>
<info delay = "+ 0.1h">
<text> GuideSampleNo.12 </ text>
<voice> GuideSampleNo.12 </ voice>
</ info>
</ guide>
In addition, the following example means “when passing the point (Point No. 14), the guidance data (GuideSample No. 14) in text and voice format is output 5 minutes before the passage time”.

<navi>
<point>
<name> PointNo.14 </ name>
<latitude> N035.03.30.0 </ latitude>
</ 1ongitude> El40.03.30.0 </ longitude>
</ point>
<info delay = "-5.0min">
<text> GuideSampleNo.14 </ text>
<voice> GuideSampleNo.14 </ voice>
</ info>
</ navi>
(B) duration
Specifies the duration for outputting information. The possible values of the attribute are as follows.

(((0 | [1-9] [0-9] *) ("." [0-9] *)? "H")?
((0 | [1-9] [0-9] *) ("." [0-9] *)? "Min")?
((0 | [1-9] [0-9] *) ("." [0-9] *)? "S")?) |
"full-time"
"full-time" means to keep the output as follows:
-If the parent element is the head element, it is left to the system.
-When the parent element is a navi element Information remains output until the next navi element becomes valid.
-If the parent element is a guide element Until the current time deviates from the range of time specified in the sibling element time element, or the current location deviates from the area of the point specified in the sibling element point element Until then, the information remains output.

  There is no default value. Setting the value when not specified is left to the system.

  The following example means that “when the point (Point No. 26) arrives within a radius of 100 m, the guidance (GuideSample No. 26) in text and voice format is output from the arrival time for 1 minute and 30 seconds”.

<guide>
<point area = "100m">
<name> PointNo.26 </ name>
<latitude> N035.04.50.0 </ latitude>
<longitude> E140.04.50.0 </ longitude>
</ point>
<info duration = "1min30s">
<text> GuideSampleNo.26 </ text>
<voice> GuideSampleNo.26 </ voice>
</ info>
</ guide>
In addition, the following example means “When a point (Point No. 45) arrives within a radius of 1 km, 100 seconds from the arrival time, text and voice format guidance (Guide Sample No. 45) will be output for 0.001 hour”. To do.

<guide>
<point area = "1km">
<name> PointNo.45 </ name>
<latitude> N035.06.40.0 </ latitude>
<longitude> E140.06.40.0 </ longitude>

(C) times
Valid only when the parent element is a guide element. If the sibling element has a point element, the information described in the info element is output each time the current location enters the area of the point specified by the area attribute, the number of times specified by the times attribute. If there is no point element in the sibling element, in other words, if there is only a time element, depending on the system, it is described in the info element as many times as specified by the times attribute within the specified time range. Information may be output. Possible values are as follows.

(0 ｜ [1-9] [0-9] *) ｜ "any-times"
"any-times" means output any number of times. There is no default value. Setting the value if not specified is left to the system.

  Specifically, in the following example, “When the point (Point No. 92) arrives within a radius of 1 km, the text and voice guidance (Guide Sample No. 92) are output up to three times from the arrival time.” Means that. In other words, when entering or leaving the specified range, guidance is given up to three times, but no guidance is given thereafter.

<guide>
<point area = "1km">
<name> PointNo.92 </ name>
<latitude> N035.11.10.0 </ latitude>
<longitude> E140.11.10.0 </ longitude>
</ point>
<info times = "3">
<text> GuideSampleNo.92 </ text>
<voice> GuideSampleNo.92 </ voice>

Next, each means of the apparatus according to the present embodiment shown in FIG. 1 will be described.

[Information presentation timing control unit 10]
The information presentation timing control unit 10 acquires the virtual time / location information sent from the time / location generation processing unit 20 and the actual time / location information sent from the sensor 25, and is described in the NVML data. Instruct the presentation / termination of information to meet various information presentation conditions. As shown in FIG. 2, the information presentation timing control unit 10 uses the point passing / arrival confirmation table 110, the navi arrival time prediction table 120, the guide information management table 130, the information presentation schedule table 140, the guidance as shown in FIG. It has a middle event management table 150.

  The point passing / arrival confirmation table 110 is a table for confirming whether or not the current point has passed / arrived through a point of the navi element or guide element. The navi arrival time prediction table 120 is based on the passage confirmation from the point passage / arrival confirmation table 110, and the guidance contents (info) and delay (point) for each point of the navi element, and the arrival prediction to the point. It is a table for managing time. The guide information management table 130 is a table for managing guide contents (info), delay (delay), presentation duration (duration), and number of presentations (times) for each point of the guide element.

  The information presentation schedule table 140 uses the delay information for each point (delay) and the presentation start time calculated from the estimated arrival time or the point passing / arrival time from the navi arrival time prediction table 120 or the guide information management table 130. It is a table for setting and managing the guidance information presentation schedule. The in-guidance event management table 150 is a table for managing the presentation period by setting the presentation end time of the guidance data in which the presentation period (duration) is defined.

  As shown in FIG. 3, the information presentation timing control unit 10 receives route guidance data (NVML data) (step S1) as guide preparation processing, as shown in FIG. 3, and calculates the arrival time from the distance between points and the speed of the vehicle. Prediction is performed and the estimated arrival time is written in the arrival time prediction table 120 (step S2).

  Only for guidance with a negative delay value, which is an attribute of how to provide guidance for the waypoint (navi), the presentation start time is obtained from the estimated arrival time and set in the information presentation schedule table 140 (step S3). ).

  Thereafter, if time data is acquired from the time / place generation processing unit 20 or the sensor 25, the information presentation schedule table 140 is referred to, and if the time coincides with or exceeds the presentation start time, presentation of the guidance is started.

  When the value of the delay of the guidance for the via point (navi) is positive, the location of the current position is checked in the point progress / arrival confirmation table 110, and the range of the specified point (point) If it is in, check the arrival status at each point by judging that it has arrived at that point. If it is confirmed that the vehicle has arrived at a certain point, a time obtained by adding a plus value of delay to the current time is set as a presentation start time and inserted into the information presentation schedule table 140.

  If the delay is not defined, the presentation of guidance starts as soon as the arrival at that point is confirmed. That is, the present time is inserted into the information presentation schedule table 140 as the presentation start time, and the guidance presentation is started immediately.

  In addition, since the arrival time cannot be predicted for the guidance of the guide point (guide), if it is confirmed by the point passing / arrival confirmation table 110 that the current point is in the range specified by the guide point (guide), the delay will occur. The time for giving guidance after the designated time is determined and inserted into the information presentation schedule table 140.

  That is, the timing for setting the presentation start time in the information presentation schedule table 140 is as follows. As for the waypoint (navi) guidance, when the delay value is negative, it is the first preparation, and when the delay value is positive, it arrives at the point. In addition, the guidance of the guide point (guide) is when it arrives within the designated range of points.

  As described above, the presentation start time is set in the information presentation schedule table 140. The guidance list in which the presentation start time is set is checked every time the current time / location is sent from the time / place generation processing unit 20 or the sensor 25, and if the presentation start time in the guidance list is reached, Guidance starts.

  Since the user may deviate from the course defined in the NVML data, the point passing / arrival confirmation table 110 is checked for such a case. If the value of the delay is negative, it is checked whether or not it has arrived at the previous point, and if it has not arrived, no guidance is presented. If it has arrived, present the specified guidance for the specified duration. The first point is not presented because it cannot be confirmed for passage or arrival. If the delay value is positive, information is entered in the information presentation schedule 140 when it arrives at that point, so there is no need to make a confirmation as in the negative case when issuing information.

  When the presentation start time is reached, a guidance start signal is output and guidance is presented. At this time, the presentation end time obtained by interpreting the guidance data presentation duration is set in the guidance event management table 150. Then, the guiding event management table 150 is checked, and the guidance is continued until the presentation end time is reached. When the presentation end time is reached, a guidance end signal is output. Information that is no longer needed after the guidance is completed is deleted from the guidance event management table 150 as needed.

  Furthermore, in the case of a guide point (guide), since it may repeatedly enter and exit the range, it is possible to specify how many times the guide is presented. Therefore, the number of times of presentation (times) is managed by the guide information management table 130, and the number of times is reduced each time information is presented. When the number of times becomes 0, it is deleted from the guide information management table 130. Note that "any-times" can also be specified. In this case, information is output as many times as it enters the specified range.

  FIG. 4 shows a process flow of the guidance presentation process. When acquiring the time / location data (step S11), the information presentation timing control unit 10 checks the passage of the point (point) using the point passage / arrival confirmation table 110 based on the location (step S12). If it has arrived at the point (step S13), the point passage / arrival confirmation table 110 is updated (step S14), and the predicted arrival time in the navi arrival time prediction table 120 is recalculated and updated (step S15).

  It is checked whether or not the delay value given to the guide information of the point is 0 (step S16), and if it is 0, the process proceeds to step S20. If the delay value is positive, the presentation start time is obtained by adding the plus (+) of the delay to the current time, and is inserted into the information presentation schedule table 140 (step S17). In addition, if necessary, based on the error between the estimated arrival time calculated in advance and the actual arrival time, the presentation start time of the guidance information with a negative delay set in the information presentation schedule table 140 is corrected. To do.

  Next, the time of the acquired time / location data and the presentation start time in the information presentation schedule table 140 are collated (step S18), and if there is guidance information whose time matches or exceeds (step S19), step S20 Proceed to If there is no corresponding guidance information, the process returns to step S11.

  In step S20, guidance is presented (step S20), information is sent to the guiding event management table 150, and the guidance presentation end time is set (step S21).

  FIG. 5 shows a process flow of the guidance presentation end process. Time / place data is acquired (step S31), and if there is data in the guiding event management table 150, it is checked whether it matches or exceeds the presentation end time of the guiding event (step S32). If the presentation end times match or exceed (step S33), a guidance presentation end command is issued, and the corresponding information in the guidance event management table 150 is deleted (step S34).

<Prediction of arrival time>
A method for predicting the arrival time will be described with reference to FIG. In the simulation mode, it is possible to determine the arrival time completely in advance. However, since the arrival time is actually not known unless the arrival time arrives, there is no choice but to calculate a certain arrival prediction time. The arrival time is the road from each point, road attributes such as legal speed and number of lanes, whether the road is congested, road conditions such as the presence or absence of an accident, weather, and user information and user information set in advance. Based on the driving history of Among these pieces of information used for prediction, road conditions, weather, and the like change in real time, so the process for obtaining the predicted arrival time needs to be repeated at certain intervals and corrected in the latest situation. As the arrival time prediction table 120 is modified, the presentation start time may also change. In this case, the information presentation schedule table 140 is also modified.

<Guidance presentation time>
As shown in Fig. 7 (A), if the delay of the guidance for the waypoint (navi) is not specified, the time of arrival at the point is set as the presentation start time, and only the presentation time (duration) of the information is given. Give guidance. When the delay is negative (-), the presentation start time is the time obtained by subtracting the minus delay from the estimated arrival time arriving at the point, and the guidance is given from the presentation start time for the presentation time (duration) of the information. Do. If the delay is positive (+), the guidance is given for the duration of the information from the presentation start time, which is the addition of the delay plus the time of arrival at the point.

  Also, as shown in Fig. 7 (B), for guidance at a guide point (guide), the time when the current point enters the area (area) specified by the guide point (guide) is the presentation start time. The guidance is given only during the presentation time (duration) of the information.

  The time (period) for presenting the guidance basically follows the presentation time (duration) specified in the NVML data. The presentation time is basically a set time for presenting data such as images and texts that do not have time restrictions on the output of information, and is limited by time restrictions such as audio and video. As for the presentation of the data originally possessed, the data is basically finished once the data is flowed. If the duration is short, the duration may be interrupted even in the middle of the situation.

  For the duration, instead of specifying the time directly, specify "full-time", and if the route point (navi) continues, it will be shown until the next route point arrives. In the case of (guide), it is possible to present all the time during the specified range. You can also specify "voice-time" to display images and text at the same time until the voice guidance ends. In this way, various guidance presentation times can be specified by simple text designation.

<How to process when guidance overlaps>
If the guidance information presentation time overlaps and the guidance sources are of the same type, for example, when voice guidance overlaps, both may not be output in hardware. Even if both can be output at the same time, if a large amount of information is presented at the same time, the user may be confused. For example, if images are presented simultaneously on multiple screens, it becomes very difficult to confirm all of them.

  Therefore, when information overlaps, it is necessary to adjust the processing by time. Therefore, first give priority to the guidance information to be presented. For example, when there is guidance information at a route point (navi) and a guide point (guide), the route point (navi) has a higher priority than the guide point (guide). If guidance with the same priority is overlapped, “Prefer later information” is set. In addition, “point guidance has higher priority than point guidance and route guidance”.

  FIG. 8 shows an example of the priority order. When the relationship between the presentation period of the previous guidance information and the presentation period of the guidance information that came later is navi, navi, guide, navi, guide, guide, The priority (priority order) is set so that the current guidance is immediately stopped and the next guidance is started. Also, when navi or guide is set, the setting is made so that “guidance is given by the end of the current guidance period and the next guidance is started as soon as the guidance period ends”.

  When information output has a length of time, such as guidance by voice or image, the presentation period of text, image, etc. may be shortened according to priority. If the output is not completed within the specified presentation period, the output is interrupted. Even if the presentation period is shortened by adjusting the priority order, the audio and video are reproduced and presented from the beginning.

  For example, as shown in FIG. 9, when the presentation period (duration) of navi1 (outputs text / image guidance 1 and voice guidance 1) and guide2 (outputs text / image guidance 2 and voice guidance 2) overlap. In accordance with the priority setting shown in FIG. 8, the text / image guidance 1 and the voice guidance 1 continue to be output until the navigation period of navi1 ends, and as soon as the guidance period ends, the text / image guidance 2 and voice guidance 2 of the guide However, when the output time of the voice guidance 1 exceeds the presentation period of navi1, the output of the voice guidance 1 is terminated halfway.

  Also, when the duration of guide2 (outputs text / image guidance 2 and voice guidance 2) overlaps with navi3 (outputs text / image guidance 3 and voice guidance 3), the priority shown in FIG. According to the setting, the output of the guidance of the text / image guidance 2 and the voice guidance 2 is stopped, and the output of the next text / image guidance 3 and the voice guidance 3 is started. Even if the output time of the voice guidance becomes longer than the presentation period, if the presentation start time of the next guidance does not come, the normal guidance is continuously output until the presentation of the long guidance ends. In addition, even when there is information on the route, it can be processed in the same way by setting the priority as a route point (navi-point), route route (navi-route), or guide point (guide-point). .

  In this way, when the presentation of guidance information is processed with priorities, information that is not presented may appear. In such a case, adjustment may be usually made so that the guide information can be presented with a delay. Also, depending on the actual guidance mode or simulation mode, the presentation start time may be set at a vacant time so that all guidance information can be presented, or the guidance information is divided in time. May be presented. Further, for example, the information to be presented may be changed according to an instruction of a user operation, for example, the guidance information is changed every time the user clicks.

  Thus, guidance information can be effectively presented by adjusting the delay and duration. In other words, it is possible to realize adjustment that presents all information or appropriately presents only necessary information depending on the application.

<Use of clearance time>
Even when the guidance is processed in this way, there are many cases where all the time is not filled with the guidance only by the guidance information written in the NVML data. Therefore, an effective service can be realized by using the time when the guide information is not presented (gap time). For example, it is possible to register information related to the point in advance and acquire and flow the prior registration information when it is found that time is available. Such a system can be used to present a commercial for a store or a notice of the next guidance, and it is also possible to collect advertising expenses based on the advertisement presented here.

<Guidance of 3D images>
When the guidance information to be presented is a three-dimensional video, the guidance is easy to understand if the three-dimensional space of the image to be presented is aligned with the current location and presented. To do so, specify as follows.

<virtual-world src = "sample.wrl"
scale = "2.0m-per-unit"
origin-x = "10.0"
origin-y = "10.0"
origin-z = "10.0"
north-x = "0.0"
north-y = "0.0"
north-z = "0.0"/>
By defining in this way, the display position and orientation of the 3D video content can be matched with the point information and the moving direction. In addition, the display size can be specified so that the actual moving distance can be synchronized with the display. That is, when 2m is advanced by simulation or actual movement, it is assumed that the unit is advanced by 1 unit in the presented virtual space. At this time, if it is displayed as if it has moved to exactly the same distance,
scale = "2.0m-per-unit"
Is specified. As a result, the actual distance traveled can be converted into a unit in the virtual space and can be presented in a synchronized manner. Similarly for video,
scale = "1cm-per-frame"
In this way, it is possible to synchronize the presentation of the video by designating the speed to advance by one frame.

  For example, there are a walk-through mode and a viewpoint movement mode in which a single object is tracked. When presenting images of streets, etc., as shown in Fig. 10, the presentation method using the walk-through mode in which the viewpoint is always directed forward is often used, and a certain characteristic building (tower, castle, etc.) is viewed. When turning around, as shown in FIG. 11, it is preferable to perform control in the viewpoint movement mode of the virtual space in which the user advances while looking at the castle. In the NVML data, basically, a via point (navi) is presented in a walk-through mode, and a guide point (guide) is presented in a viewpoint movement mode that advances while looking at a specific direction.

[Sensor 25]
The sensor 25 measures the actual time and location by using GPS using an artificial satellite, a location management system that determines the location from the base station location of a mobile phone or PHS, etc. at a certain interval, and provides information presentation timing. The transmission to the control unit 10 is repeated.

[Time / place generation processing unit 20]
The time / place generation processing unit 20 controls the generation of time / place data in order to perform appropriate guidance / simulation according to the situation. As shown in FIG. 12, playback / fast forward / skip / wind It comprises an operation interface 210 for operating various operations such as returning, a vehicle speed / time step setting unit 220 for setting vehicle speed and time step, and a time / location generator 200 for generating time / location data.

  The time / location generation processing unit 20 acquires vehicle speed and time step information by the vehicle speed / time step setting unit 220, and based on the operation input from the operation interface 210, the time / location generator 200 generates the time / location generator 200. Location data is generated, and the time / location data is passed to the information presentation timing control unit 10.

  Specifically, the route is read from the received NVML data, the vehicle speed / time step setting unit 220 acquires the vehicle speed and time step, calculates the required time from the relationship between distance and speed, and calculates the time. The advance width is calculated according to the step. Calculate points that enter (exit) the guidance range of the guide point (guide) on the route and generate time / place data. It should be noted that the generation of time / place data is stopped, executed, or quickly performed in response to a request from the operation interface 210.

  In addition, the time / place generation processing unit 20 has various modes for use in normal simulation, and can change the way of generating time / place data in various ways. For example, you can guide the actual guidance by simply reducing the scale, proceed slowly through the part where the guidance information is output, skip each guide alone (skip), or move all vehicles at the same speed. In this way, the proper use according to the purpose is performed by changing the mode.

  As a basic process, the process is performed by shortening the real time, but also a process for controlling so as not to skip the time / place where the guidance is presented. Since the time is recorded in steps, if the step is large, both time and place will jump greatly, and time and place data corresponding to the start time and points of guidance set in the information presentation schedule table 140 are generated. Failure to do so could mean that no guidance is presented. In normal guidance presentation processing, this time step is sufficiently short so that it is unlikely that guidance will not occur, but in the case of simulation, it may move at high speed, so the time and place where guidance should be presented jumps over. It often happens.

  Therefore, the points for presenting the guidance are calculated in advance, and at least the step width is changed so as to pass through the points to generate time / place data. Specifically, when the time step width exceeds the point for outputting information, the step width is shortened and adjusted.

  First, as shown in FIG. 13A, each point (route point navi) is acquired from the route. Next, as shown in FIG. 13B, a passing point which is an intersection of a circle and a route representing the range of the guide point (guide) is obtained. In addition, calculate the points for giving guidance that takes delay into consideration, the points to end guidance that takes into consideration the duration of presentation, and make sure that the time and place (passage points) related to guidance are generated. .

  Next, as shown in FIG. 14A, the advance width is calculated according to the basic steps calculated from the vehicle speed and time. As shown in FIG. 14B, when the basic step jumps over the place (passing point), the step is shortened to the step up to the passing point and adjusted.

  In addition, the point of the point itself when the guide point is shifted due to the intersection or delay behind the circle representing the range of the guide point (guide) does not affect the guidance, so it does not need to stop. However, since it is easier to see at these milestones in the actual guidance, in this example it was set to stop at these points.

  Also, a method of generating time / location data by two timers may be used. In this method, as shown in FIG. 15, a time / place event is generated using a timer with a constant interval and an event timer based on a preset guide.

  In addition, when simulating movement using multiple types of vehicles, the difference in the actual vehicle speed between vehicles should remain, but if the simulation is performed with the same speed difference as the actual vehicle, the case of high-speed vehicles It may be difficult to see the guidance presented in In this case, for example, the speed is averaged using a function (speed filter) as shown in FIG. By doing so, it is possible to perform a simulation that makes it easy to see the guidance while leaving a difference in vehicle speed.

  Further, in the case of processing such as slowly proceeding or stopping during guidance, as shown in FIG. 17 (A), the time / location progress is stopped at the start of voice guidance, and the time is stopped at the end of voice guidance.・ Resume the progress of a place, or as shown in FIG. 17B, a time / place event is generated by a playback command from the operation interface 210 and stopped by a stop command. A place event may be generated. Similarly, if the current state of guidance is received and guidance is in progress, only the time is advanced and the place is stopped, and when the guidance is over, it starts moving again, or only the guidance time is the same as real time. It is also possible to advance at a faster speed where there is no guidance.

  FIG. 18 shows a processing flow of time / place generation processing. When the route is read from the NVML data (step S41), the speed of the vehicle and the distance traveled once from the time step are calculated (step S42). Next, a point A that enters / exits the guidance range of the guide point (guide) on the route is calculated (step S43). Further, the absolute time B of the presentation start time for presenting the guidance for which the delay has been calculated is calculated (step S44).

  Based on the above calculation result, it is determined whether the place or time to be reached in the next step exceeds the point A or the time B (step S45). Alternatively, the time / place data of the time / place event is generated by changing to steps up to time B (step S46). If not, time / place data is generated in the normal basic step (step S47).

  As described above, by controlling the generation of time and place with the time and place generator 200, various guidance and simulations can be realized. In addition, the information presentation timing control unit 10 only gives guidance information corresponding to the received time and place information regardless of whether it is a virtual time or place or an actual time or place. It will be easy to control.

<Operation interface 210>
The operation interface 210 can be used with an operation interface similar to that of audio, for example. In the example of the operation interface shown in FIG. 19, in order from the right, pause 210, skip (jump to the next point) 211, fast forward 212, playback 213, reverse playback 214, reverse fast forward 215, reverse skip 216, stop 217 Has buttons to perform operations. When these buttons are pressed, the instruction is sent to the time / location generator 200, and time / location data corresponding to the instruction is generated. Fast forward 212 multiplies the speed of the vehicle. At this time, as described above, the guidance presentation time may be shortened in the same manner, or the mode may be switched to return to the normal speed only while the guidance information is being presented. . The skip 211 represents a process of flying to the next point, and even during guidance, the guidance is interrupted to fly to the next point. It may be set to fly after the presentation of the guidance information is finished. Reverse playback 214, reverse fast forward 215, and reverse skip 216 are functions for playing back the route in reverse. In the case of processing according to this instruction, the description of “left / right” or “front / rear” in the text written in the NVML data is automatically changed to “right / left” in order to ensure consistency of route guidance. , Convert to “after” and present the guidance.

  In addition to this method of operation, there is a method of working directly on a point to view information. You can make a point accessible directly using map controls or tree-style controls that are displayed by pull-down menus or pop-up windows in the menu bar.

  For example, if a via point is displayed in a pop-up window type as shown in FIG. 20A or a pull-down menu type window as shown in FIG. It may be. Thereby, the same effect as the skip selection in the operation interface example shown in FIG. 19 is obtained. The items to be entered in the menu may be expressed in an abstract order (“via point 1, via point 2,...”) As shown in FIG. 20A, or NVML data as shown in FIG. 20B. The value of the point may be read and the name of the point (“aaaaaa, bbbbb,...)” May be directly displayed. Such a menu can be displayed when a certain button is clicked, or traced from a menu bar or the like. The user uses these menus when necessary and performs necessary selection operations.

  Similarly, as shown in FIG. 21, it is also possible to embed and display point information in an 8-button menu 220 as in a car navigation system. Such an 8-button menu 220 is composed of a button and a function of a button displayed on the screen. When the button is pressed, processing of contents displayed on the screen is performed. In this case, the user can move to the displayed place and see the guidance if there is guidance. For example, as shown in FIG. 21A, when the button corresponding to the entire menu guidance is pressed, the entire route is displayed on the map. When the button corresponding to the waypoint 6 is pressed as shown in FIG. 21 (B), the periphery of the waypoint 6 is enlarged and displayed, and guidance for the waypoint 6 is presented. For details of the operation interface 210 such as the 8-button menu 220, refer to Japanese Patent Application No. 10-200277 (Japanese Patent Laid-Open No. 2000-029595) “Electronic Processing Device Having Menu Interface”.

  The operation interface 210 for operations based on these points directly issues an information presentation command at that point to the information presentation method control unit 30 without passing through the time / place generator 200 that dynamically generates time and place. , Guidance may be presented through various guidance dialogs.

<Vehicle speed / time step setting unit 220>
The vehicle speed / time step setting unit 220 sets the speed for each means of transportation such as a car or a walk. It is also possible to change the speed of the same vehicle when driving on a general road or driving on a highway. Furthermore, it is also possible to perform simulations using more realistic speeds using actual traffic information. Also, if you try to see the guidance at the same speed as the actual speed in the simulation, it will take a very long time, so you can set the time step arbitrarily so that the actual 5 minutes is 1 second in the simulation. To do. This will allow you to experience the entire guide in a short time.

[Information presentation method control unit 30]
The information presentation method control unit 30 receives the information presentation start / end signal received from the information presentation timing control unit 10 and uses the type of terminal used by the user (CPU processing capacity, screen size). Etc.), and what kind of display means (view system) is used to determine what information is displayed in which place, how to display the tree format control unit 61, map format control unit 62, text A presentation start command is issued to the format control unit 63 and the guidance dialog control unit 64.

  For example, when the present embodiment is applied to a car navigation system, guidance information is output in a map format, and a guidance dialog is output as necessary. The guidance may be adjusted in such a way that only voice information is output during traveling, and guidance information such as text and images is also output while the vehicle is stopped. When the present embodiment is applied to a mobile phone or the like, since the presentation screen of the mobile phone or the like is small, guidance is provided only by text or voice.

  It is also possible to control where and what type of guidance information is output by a certain format. For example, a file having the following description information is prepared for each terminal.

file: ex1.
Point: Icon Route: Route Calculation Guide Information: Balloon Information for the whole course: Upper left window
file: ex2.
Point: Display in text area Route: Straight line Guidance information: pop-up
The information presentation method control unit 30 reads the contents of this file and presents guidance information in an appropriate manner according to the instruction. Similarly to the above description, an API (Application Programming Interface) possessed by each device can be directly described and processed using the API.

[Tree presentation control unit 61]
As shown in FIG. 22, when receiving the NVML data, the tree format presentation control unit 61 displays the course outline, the point information, the guidance information, etc. in the tree display area 230 in the tree format in the order of the route. Detailed information is displayed at lower levels. Each level can be opened and closed by clicking, etc., and information can be displayed by changing the level of detail. Thereby, unnecessary detailed information display can be hidden, and the listability can be increased.

  Each information has a link, and this link can present a dialog for viewing and editing each information. In addition, a link centered on the selected point can be displayed in cooperation with the map format presentation control unit 62 by a link attached to each piece of information.

  In addition, an editing function is provided that can be easily moved or copied for each block by dragging the information displayed in the tree display area 230. As a result, it is possible to easily perform processing such as exchanging the entire point information or copying only the guidance information portion. Also, by changing the place of the waypoint (navi), the order of waypoints is automatically changed so that the order of passing the waypoints can be changed easily. In addition, when a save instruction is received after editing the map information or the like on the tree display area 230, it is written and saved as NVML data. The process of decoding the NVML data and displaying it in the tree display area 230 as shown in FIG. 22 and the process of converting the information displayed in the tree display area 230 into the NVML data need not be described in detail. Obviously, it can be easily implemented from the nature of the NVML data.

  In order to make the detailed information easy to see, during the presentation process, in the tree display area 230, the lower level of the corresponding point or route information is opened to show the detailed information according to the moving position, and other points are displayed. The display is kept closed at, and the display is automatically made easy to see. Further, detailed information on the portion of the guidance may be opened in accordance with the guidance presentation period. For example, as shown in FIG. 23, the detailed information of the lower hierarchy of point 4 is displayed while passing through the guidance range of “point 4”, and the display of these detailed information is closed after passing. Similarly, the details of the portion being edited may be opened in synchronization with other editing means.

[Map format presentation control unit 62]
FIG. 24 shows an example of map display by the map format presentation control unit 62. Upon receiving the NVML data, the map format presentation control unit 62 allocates the NVML data on the map and displays it in the map display area 240, for example, as shown in FIG. A white pin icon 241 is displayed at a location (latitude, longitude) corresponding to the via point (navi). In addition, it is good to make the numbered icons easy to understand the order of transit. The name of the point may be written under the icon.

  If there is a route, the specified route is drawn with a bold color to make it stand out. In particular, when no route is designated, a straight line connecting the icons at the waypoints in order is drawn as shown in FIG.

  In the case of a guide point (guide), a pin type icon 242 for linking with the detailed information is displayed at the center, and the area (area) affected by the information is displayed in a figure such as a circle. The pin type icon 242 is surrounded. For example, if the information is output when entering the radius of 400m of the guide point "Tokyo Tower" (<point area = "400m">), as shown in FIG. Display a circle on the map. Guidance information is linked to this icon, and when clicked, the guidance information is output through various guidance dialogs.

  If the route is not specified and only the means of transportation (means) is described in the NVML data, look at the “means” tag in the NVML data, search for a normal route for a car, and the train route for a train. Depending on the method, the route search process is used differently, such as figure search and walking route search for walking. If the route search is completed, the route is displayed. If not, the route points are connected by straight lines.

  When a plurality of points are set to overlap for the same place, the icons indicating the points overlap and become difficult to see, so the icons are shifted and displayed. For example, as shown in FIG. 25, pin-shaped icons are used to indicate points, and pin-shaped icons are extended and displayed in different directions, so that they can be displayed while being overlapped to some extent. Also, a plurality of NVML data can be displayed in an overlapping manner by changing the route to be displayed and the color of the icon. As a result, the positional relationship between the courses can be understood at a glance.

  While the guidance is being executed, the map to be displayed is followed in accordance with the movement of the current position, and a map centered on the current location is always displayed in the map display area 240 using an icon indicating the current location (for example, a vehicle type icon). . Or, when the vehicle type icon reaches the end of the map screen, it is possible to select a display method with less map rewriting drawing processing according to the access speed to the map information. Further, the map scale may be automatically changed according to the speed of the vehicle. In order to read map data at high speed, various ideas such as prefetching and acquiring data in a large range in advance are required.

  Further, depending on the content of the NVML data guidance, the vehicle type icon is changed as appropriate, such as a tour conductor type icon, and displayed. Thereby, it is possible to give an impression to the user as if he / she is receiving a tour guide.

  As an input means, it is possible to input values such as latitude and route that are generally difficult for humans to input directly by hand, such as by clicking a certain point on the map. As a result, the point information of the NVML data can be input easily and intuitively. In this procedure, when a point on the map is first clicked, a dialog window 300 for selecting a waypoint or a guide point is displayed as shown in FIG. When the user selects either of them, as shown in FIG. 26B, the latitude / longitude of the waypoint or guide point is automatically acquired, and dialog windows 310 and 320 for prompting the user to input other information on the point are displayed. To do. The user can input unset information about a point or guidance information associated with the point on the dialog windows 310 and 320. Note that the location / route database access unit 70 may be used to automatically acquire and display other information such as the name, category, address, and postal code of the location. When “OK” is clicked on the dialog windows 310 and 320, the location information and guidance information for the location are registered, and a pin type icon is displayed on the map. A series of route guidance data can be created by repeating such operations.

  In addition, it is possible to change the designated point by dragging a waypoint or guide point on the map. In this way, the user can create NVML data simply by inputting information such as a point as if drawing.

  Since the map format presentation control unit 62 only acquires map data as an image and displays the NVML data by aligning the map data on the map data, even if the displayed map portion is a general picture. Similar processing can be performed. In many cases, a guide map is represented by a deformed map whose scale such as size and length is not accurate. In such a case, the latitude / longitude portion of the NVML data is changed to a coordinate expression, and a point corresponding to each point is clicked to create NVML data. By executing this, similar guidance can be realized. As described above, the combination of the background picture information and the NVML data icon can be a kind of animation creating means.

[Text format control unit 63]
The text format control unit 63 performs integrated control when inputting / outputting NVML data as text.

  First, when the NVML data itself is handled, it can be described freely when the user inputs it, so it is necessary to check whether it is as per the grammar or conforms to the NVML specification. Further, after that, the guide data evaluation unit 90 evaluates the feasibility and validity. When NVML data created by another module or device is written as text data, it is necessary to make it easier to see by adding indentation. The text format control unit 63 has these processing functions.

  Next, control is performed to present the guide by converting it into a text-friendly form. This is used when only text data can be displayed depending on the terminal, or when other than text data cannot be transmitted due to communication capacity. For example, when transmitting to a mobile phone, the text is automatically converted and reduced to fit within the display screen size of the mobile phone, or the map is described in text and sent. In addition, when outputting as a printed matter, the text data is converted into a format that is easy to view as a printed matter and output.

[Guidance Dialog Control Unit 64]
The guidance dialog control unit 64 outputs summary information, point information, route information, guidance information by text and images, etc., or controls a dialog window for editing. This dialog window allows the user to browse and edit detailed values for each piece of information.

  The guidance dialog control unit 64 is dynamically controlled in accordance with an instruction from the information presentation method control unit 30, or is activated from another application for the purpose of browsing or editing. It operates in conjunction with other tree format presentation control unit 61 and map format presentation control unit 62 based on the point information. For guidance information by voice, it is possible to use a dialect that suits the region.

[Data communication control unit 40]
The data communication control unit 40 performs NVML data communication. In some cases, the entire NVML data is transmitted or received, or in response to a request from the information presentation method control unit 30, image or audio guide information is acquired from the outside through communication as necessary. In addition, accompanying information such as a map or information such as a CM that flows in a gap between presentations may be transmitted and received.

  For efficient data transfer, do not download all NVML data first, but acquire large data such as images when that data is needed or will be needed There is also a processing function.

[Guidance data access unit 50]
The guide data access unit 50 provides various APIs for facilitating access to guide data. Simple commands are provided for adding and deleting points, changing the order, etc., so that you can add / delete points, change the order, handle the guide points and waypoints separately, It is possible to manage the order of each guide point and waypoint and the total order. In addition, when a new point is added, it has a processing function for calculating and adding a position where the total distance of the route becomes short as well as adding it at the end of the route.

[Point / route database access unit 70]
The point / route database access unit 70 automatically extracts point information necessary for guidance from the point database. In addition, information associated with points and guidance information are extracted from various databases such as tourism, customers, shops, public facilities, history, and in-house data. Information such as points, search range, search conditions, etc. is obtained from the tree format presentation control unit 61, map format presentation control unit 62, text format control unit 63, guidance dialog control unit 64, and guidance data access unit 50, and is necessary from the database. Information is returned to the request source. It is also possible to search collectively for a plurality of points and routes included in the NVML data.

  Japanese Patent Application No. 11-113191 “Guidance information presentation device, guidance information presentation processing method, recording medium recording guidance information presentation program, guidance script” Recording medium, guidance script generation apparatus, operation management apparatus and method using guidance script, and program recording medium thereof, time adjustment apparatus and method for traveling using guidance script, program recording medium thereof, and guidance plan creation The technology relating to “guidance plan creation device” of “device, method and program recording medium thereof, guidance information providing device, method and program recording medium thereof” may be used.

[Guidance automatic creation processing unit 80]
First, manual NVML data creation processing will be described with reference to FIG. When new creation is selected on the displayed map (step S51), a point is designated by double-clicking a point on the displayed map (step S52). By using a dialog window as shown in FIG. 26A, a waypoint and a guidance point are selected (step S53), and point information about this point is input via the point / route database access unit 70 (step S54). Further, guidance information is input (step S55). It is determined whether or not all necessary points have been input (step S56), and steps S52 to S55 are repeated until all necessary points are input. When all the points have been input, a route connecting the input points with the shortest distance is automatically created using a known route search technique (step S57), and NVML data is generated and output (step S57). Step S58).

  When two points of a departure point and a destination point are sent, the automatic guidance creation processing unit 80 automatically creates guidance information for a route between the two points. The process at this time will be described with reference to FIG. First, when two points of a departure point and a destination point are specified on the map presented in the map display area 240 as shown in FIG. 29 (step S61), a route calculation between the two specified points is performed and a point sequence is obtained. Obtain (step S62). Usually, the route calculation is obtained by searching by the Dijkstra method using a network map as shown in FIG. Then, a bent path is created at a plurality of reference points (points).

  For each point (passing point) on this route, the direction of entering and exiting the point are compared (step S63), and the turning angle is obtained based on this direction difference (step S64). It is determined whether or not the point is a big turn (step S65), and if it is a point that turns so much as to get lost unless guidance is given, turn right and turn left. Guide information such as “Please turn” and “Please make a U-turn” is created and assigned to the point (step S66).

  For example, an image of an arrow 410 in a turning direction as shown in FIG. 31 is attached as guide information. If the delay (delay), which is the timing for presenting this information, is set to about "-2min", when this guidance is executed, the voice and text guidance "Please turn left" and two minutes before the turn An image of an arrow in a turning direction can be output. Furthermore, if an image of the intersection prototype 420 such as a crossroad, a T-junction, and a Y-junction as shown in FIG. 32 and the image of the previous arrow 410 are combined and given, a more easily understood guide image can be created.

  In addition, when the feature database 430 relating to incidental information such as points and buildings can be used by the point / route database access unit 70, landmark information obtained from the feature database 430, traffic signs, and incidental information on roads (intersection names) Or the presence or absence of a signal) is attached to the above image to make it easier to understand. Needless to say, a photograph of the facility may be taken out from the feature database 430 and used as guide information. By creating guidance information in this way, guidance (text, voice) such as “Please turn right at the intersection with a signal at the corner of the convenience store” can be provided. These pieces of information are output as NVML data (step S67).

  Even if there are two or more points specified on the map, the same processing can be performed for all two points, exactly the same as the processing between the two points of the departure point and the destination described above. It is.

  When such a method for creating a guide image by combining basic elements is used for guidance using a communication network, as shown in FIG. If the image information of the arrow 410 and the information of the intersection prototype 420 are possessed, the center 450 side simply sends the turning direction and the intersection type, and if necessary, the feature information ID, and the terminal 440 side transmits these. A guide image can be created by synthesizing and the amount of information transmitted over the network can be reduced. The feature information ID includes, for example, information on a landmark 435 that serves as a landmark of a convenience store, a gas station, or the like.

  FIG. 34 shows a display example when the obtained route is presented in the map display area 240 and the point information and guidance information of the waypoints (route points) are presented in the tree display area 230.

[Guidance data evaluation unit 90]
The guidance data evaluation unit 90 determines whether or not the route guidance data is suitable, and corrects or complements the data depending on the case. As shown in FIG. 35, first, when NVML data is acquired (step S71), a grammar as to whether or not the NVML specification is met is checked (step S72). For example, whether or not both latitude and longitude are specified, telephone number, FAX, E-mail address, URL, geodetic system notation, whether there is a vehicle notation method, guidance Check whether there is a description of the attribute to execute (for example, guide cannot specify a negative value for the delay attribute).

  Next, the feasibility is checked (step S73). For example, specify a point that does not exist using the geographic information system, whether it is a course that can be reached within time due to the relationship between time and distance, whether it is not going to pass through the road network information. Check if it is not.

  Next, the validity is checked (step S74). Even if it is feasible, data that is abnormally detoured or that the guidance is too open is not valid data. Also, the guidance information is not effective in a place where the guidance data overlaps and cannot be displayed. Therefore, an evaluation function is used to determine whether the data is valid, and an alternative is output if necessary (step S75).

  The necessity of correcting such route guidance data also changes depending on road conditions such as traffic jams, construction, and accidents, and weather, so it may be necessary to correct in real time. In such a case, the actual guidance course and guidance contents are corrected in real time and reflected in the information presentation method control unit 30 and the guidance dialog control unit 64. For alternatives, refer to the map information database for alternatives such as changing the movement of cars to trains or promoting the use of expressways for some routes that are likely to be delayed in time. And make suggestions to the user.

[Application by combination of each means]
A tool for processing guide data having various functions can be created by making each means for realizing the present embodiment described above into parts and combining these parts. Here, componentization means preparing each as a separate program module, or preparing each as a module that can be called in a subroutine format or a function format. In a system using object-oriented programming, it may be prepared as an object.

  FIG. 36 shows an example of creating the NVML editor 500 and the NVML player 600 by combining the modules shown in FIG. 1 as parts. For example, as shown in FIG. 36, when a module of the tree format presentation control unit 61 and map format presentation control unit 62 is combined with an appropriate operation menu 65 or the like, a simple NVML data editing tool (NVML editor 500) can be obtained. When the map format presentation control unit 62, the guidance dialog control unit 64, and the like are combined, the NVML player 600 is obtained.

  FIG. 37 shows an example of a display screen of the NVML editor 500 that is an editing tool. The editing screen of the NVML editor 500, which is an editing tool, includes an operation menu 1101, a map operation icon 1102, a map display area 1103, and a tree display area 1104.

  Furthermore, as shown in FIG. 38, various databases 510 such as tourism, customers, shops, public facilities, history, and in-house data and a point / route database access unit 70 are attached to the module used as the NVML editor 500. In addition, a guidance data evaluation unit 90 that performs feasibility evaluation and validity evaluation of the generated and edited route guidance data is added, a module that takes in information from the advertisement server 520 is added, and route adjustment with other users is performed. The NVML data creation application 700 can be created by adding a route adjustment unit 530 that performs the above and a guidance automatic creation processing unit 80 that automatically creates guidance data.

  FIG. 39 shows an example of the browser screen of the NVML player 600. The NVML player 600 executes the time / place generation processing unit 20, the information presentation timing control unit 10, and the information presentation method control unit 30 behind the scenes while using a map format presentation control unit 62, a guidance dialog control unit 64, and the like as interfaces. Use to simulate the guidance. The browser screen includes, for example, an information display area 1112, a map display area 1113, a latitude / longitude display area 1114, a text display area 1115, an image display area 1116, a map move button 1121, a scale change button 1122, various setting buttons 1123, a simulation A start button 1124, a fast-forward button 1125, an end button 1112, a reset button 1127, and the like are provided.

  Furthermore, as shown in FIG. 40, by combining necessary means according to the processing capability of various terminals such as a personal computer (PC) 810, a personal digital assistant (PDA) 820, a mobile phone / PHS 830, and a car navigation system 840. , Guidance using NVML data can be executed.

  The PC 810 having the NVML processing engine 811 acquires a map from the external map server 850 and NVML data from the NVML content server 860 to execute guidance. When the PC 810 includes the map system 812, it is only necessary to acquire NVML data, and there is no need to obtain a map from the map server 850. When the PC 810 includes the simulator engine 813, guidance can be executed in the simulation mode.

  The PDA 820 passes its own position measured by the self-position measuring function 821 to the NVML processing engine server 870, whereby the NVML processing engine server 870 obtains NVML data from the NVML content server 860 and sends guidance information to the PDA 820. , PDA 820 executes guidance based on the received guidance information and a map obtained from map server 850 as necessary.

  The cellular phone / PHS 830 obtains guidance information from the NVML processing engine server 870 based on the location information from the cellular phone / PHS location management system 880 and executes guidance.

  In the car navigation system 840, the NVML processing engine 841, the map system 843, and the self-position measurement function 842 are provided, so that the NVML data is directly obtained from the NVML content server 860 and guidance is executed.

  In this way, by making each means for realizing the present embodiment into parts, various functions can be easily replaced, and anyone can easily develop them, and can be easily incorporated into other systems.

  Each unit of the device according to the present embodiment can be realized as a partized program. As shown in FIG. 41, each means is connected to each other or to a user program by passing messages by API or message communication means. 41, the NVML data access unit 1201 is the guidance data access unit 50 shown in FIG. 1, the information presentation method controller 1202 is the information presentation method control unit 30, the information presentation timing controller 1203 is the information presentation timing control unit 10, The time / location generator 1204 is in the time / location generation processing unit 20, the map database access controller 1205 is in the point / route database access unit 70, the automatic route creation module 1206 is in the guidance automatic creation processing unit 80, and the NVML evaluation module 1207 is in guidance. Each corresponds to the data evaluation unit 90.

  The basic functions of the NVML data access unit 1201 are access to NVML data (read, write), consistency check of NVML data, point operation, type conversion (latitude / longitude, character string, numerical value, etc.). This facilitates handling of NVML data.

  The basic function of the time / location generator 1204 is to generate time / location from NVML data and simulation setup data. It has a step timer that generates time and place simply by increments and an event timer that generates time and place according to the arrival timing and guidance timing of each point. This makes it possible to simulate a moving object using NVML data.

  The basic function of the information presentation timing controller 1203 is to interpret the info attribute (delay, duration, times) and the point attribute (area) and present the guidance start time and end time. In addition, guidance is given according to the priority order of via points (navi), guide points (guide), points (points), and routes (routes). It also manages arrival time, point passing information, and various tables for guidance presentation schedules. As a result, the timing for presenting the NVML guidance data can be controlled, and the management of the guidance data can be easily realized.

  The basic function of the information presentation method controller 1202 is to select a view system (map, tree, dialog, etc.) and manage the position and size for arranging them, and the platform (PC, car navigation system, mobile phone, television, PDA). Etc.) and setting the necessary components and display size. Thus, by managing all the display size and position, NVML data processing can be designed without being aware of the display.

  Further, the map format presentation controller 1233 is in the map format presentation control unit 62, the tree format presentation controller 1234 is in the tree format presentation control unit 61, the text view 1213 is in the text format control unit 63, the guide point dialog 1221 and the waypoint dialog 1222. , Via dialog 1223, guidance information presentation dialog 1224, summary dialog 1225, and remarks dialog 1226 correspond to guidance dialog control unit 64, and NVML communication controller 1214 and print module 1215 correspond to data communication control unit 40, respectively.

  The basic functions of the map format presentation controller 1233 are to express the NVML data on the map and to correct the NVML data by operating the points on the map. Thereby, the NVML data can be displayed on the map, and the positional relationship becomes easy to understand. Further, it becomes easy to input geographical data such as latitude and longitude among the NVML data.

  The basic function of the tree format presentation controller 1234 is to represent the NVML data on the tree and to edit the NVML data by an operation on the tree. As a result, it is possible to exchange points by using a GUI (Graphical User Interface), which is convenient. Also, it becomes easier to edit by organizing the nested structure.

  Each of these means can be stored in an appropriate recording medium such as a portable medium memory, a semiconductor memory, or a hard disk that can be read by a computer.

  Various application programs can be realized by combining the individual modules shown in FIG. FIG. 42 shows an implementation example of the application program.

  FIG. 42A shows an implementation example of an NVML player that performs a simulation of guidance and the like. The NVML player includes an NVML data access unit 1201, a time / location generator 1204, an information presentation timing controller 1203, an information presentation method controller 1202, a map format presentation controller 1233, and various information display dialog 1300 modules shown in FIG. It can be realized by combining as shown.

  FIG. 42B shows an implementation example of a navigation system that performs actual route guidance. The navigation system includes an NVML data access unit 1201, a location and time sensor driver module 1310, an information presentation timing controller 1203, an information presentation method controller 1202, a map format presentation controller 1233, and various information display dialog 1300 modules as shown in FIG. It can be realized by combining as shown in FIG.

  FIG. 42C shows an implementation example of the NVML editor that creates and edits NVML data. The NVML editor can be realized by combining the NVML data access unit 1201, the map format presentation controller 1233, the tree format presentation controller 1234, and various information display dialog 1300 modules as shown in FIG.
