Description

[Technical Field]

[0001] The present invention relates to a system and a program that include a control means for displaying information about a travel route on a display means together with information about a set route, for example. [Background technology]

[0002] There are various types of electronic devices installed in automobiles, such as radar detectors and car navigation systems. These electronic devices have, for example, a control means for controlling the device, a memory means for storing various information required for control, a display means for displaying the results of processing by the control means, and a GPS receiver for receiving GPS signals from satellites to obtain current location information. The display means is composed of a small display or the like, and this display is placed near the driver's seat, and the user operates the electronic device by inputting from a touch panel, remote control, or the like.

[0003] These electronic devices have a route guidance function that generates a route to a destination specified by the user and guides the user along that route. In route guidance, when the user inputs the destination via a touch panel, remote control, or the like, the device generates a route from the current location to the destination. Several route candidates are displayed based on factors such as cost (whether toll roads should be used) and time. The user selects a desired route from the displayed candidates. The electronic device then sets the selected route as the guidance route and starts route guidance. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-289655 [Patent Document 2] Japanese Patent Application Laid-Open No. 2003-42783 [Patent Document 3] Japanese Patent Application Laid-Open No. 2010-190592 Summary of the Invention [Problem to be solved by the invention]

[0005] When users are going to a completely unfamiliar destination, they are unlikely to be dissatisfied with the route presented by their electronic device, but when they are going on a long drive to a place they have been to several times and know the route to some extent, but are a little unsure of their memory, they often feel that they would like to take a route other than the one presented. Routes are set from practical perspectives such as cost and the shortest distance, and users who are traveling for sightseeing purposes often find the route unsatisfying.

[0006] Also, for example, if a passenger knows a shortcut rather than the driver, they would like to tell the driver the way, but the shortcut is often complicated and it is often not easy to explain the way, which can be inconvenient.

[0007] Therefore, technologies have been proposed that allow users to create their own routes on their own PCs at home and transfer the created routes to electronic devices, as well as technologies that allow users to edit route history stored in electronic devices using a PC (see, for example, Patent Documents 1, 2, and 3).

[0008] The above-described technology makes it possible to travel along a route created by the user. However, even if a user creates a route, the electronic device merely provides mechanical guidance, similar to a route set by the electronic device. However, actual travel often does not remain on such a pre-set route. When actually traveling, people may deviate from the route depending on the scenery they see. Along the way, people also make various memories by stopping at tourist spots, visiting temples and shrines, purchasing souvenirs, and enjoying meals. And after the trip, people want to enjoy those memories. Conventional electronic devices lack the hospitality that supports the true joy of travel, from planning ahead to creating memories during the trip and enjoying them after the trip.

[0009] The present invention has been proposed to solve the above-mentioned problems of the prior art, and aims to provide a system that is highly convenient and entertaining. [Means for solving the problem]

[0010] (1) The system according to the present invention includes a control means for acquiring information about a user's driving route and displaying the information on the display means together with information about a set route that the user set before driving.

[0011] For example, when traveling by car, you may plan your route in advance to efficiently visit the tourist spots you want to visit. However, when you actually set off on your trip, you may find that the road you planned to take is congested or that something catches your eye, and you may find yourself changing your route on the spot. Such flexible changes to your plan are one of the joys of traveling, and when you look back on it later, you will remember it as one of the fun events of your trip.

[0012] For example, after a trip is over, the user can relive the real memories of the trip by displaying the route they traveled and retracing that route, but by also displaying the route they had planned to travel in advance, they can vividly recall events related to changes in plans. In other words, a highly convenient system can be provided that supports users in enjoying their travel memories.

[0013] You can also consider whether the change in plan was successful, whether you should take the route you missed due to the change in plan, and discuss this with your companions, which can be useful for planning your next trip.

[0014] The information about the travel route may be, for example, the travel route that the user actually traveled and information about it. It may include not only the travel route itself, but also, for example, information about images taken on the travel route and audio recorded on the travel route. The travel route may be, for example, a route traveled by the user driving a vehicle such as a car, motorcycle, or bicycle. Alternatively, it may be a route traveled or walked on the user's own feet while jogging, hiking, trekking, etc. For example, the system may be equipped with an electronic device equipped with a GPS such as a navigation device or a smartphone, and the electronic device may obtain information measuring the position and direction of travel of the user or vehicle to create travel route information. Display of the travel route on the display means For example, the roads on the map may be displayed in color to make them stand out.

[0015] The information about the set route may be, for example, a set route set as a travel schedule before the user sets off and related information. It may include not only the set route itself but also, for example, information about tourist spots and traffic information along the set route. The set route may be easily created using an application that calculates a recommended route based on input of various conditions, such as the starting point, end point, intermediate points, and travel time. For example, the system may include an electronic device with this application installed, which calculates a recommended route based on user input and creates a set route according to the user's selection. The display means may display the set route by, for example, coloring roads on a map in a conspicuous color, preferably a color different from the travel route, to make it easier to distinguish.

[0016] The control means may be provided in, for example, an electronic device, and the electronic device may be, for example, a PC so that the user can enjoy memories at home. Alternatively, the control means may be a small electronic device that the user can carry, such as a mobile phone, smartphone, or portable navigation device, so that the user can easily enjoy memories of their trip even when they are out and about. Furthermore, the control means may be an in-vehicle electronic device, such as a car navigation device or radar detector, so that the user can immediately enjoy memories while traveling by car.

[0017] The display means may be, for example, a display screen that allows the user to visually recognize information. For example, it may be a display screen of the electronic device itself that is equipped with the control means. Alternatively, it may be, for example, a TV screen connected to the electronic device. This allows the user to enjoy memories of the trip on a large screen. Alternatively, it may be a screen that is projected onto a screen or wall by a projector connected to the electronic device. Using a projector is advantageous because, for example, the user can easily enjoy memories while traveling by projecting images onto the wall of a lodging facility.

[0018] If the system is equipped with a touch panel type electronic device, it is advisable to display a map on the touch panel and provide buttons for the user to perform various input operations, such as buttons to move the cursor or to replace the right and left buttons of a mouse.

[0019] Furthermore, for example, when a projector is connected to a touch panel type electronic device, a map can be projected onto a screen or wall, and buttons for the user to perform various input operations can be displayed on the touch panel, allowing the user to enjoy memories of their trip on a large screen while easily operating the electronic device at hand as a remote control.

[0020] (2) The control means may, for example, acquire points set on the travel route and information related to the points and display them on the display means. By displaying any points set on the travel route together with information related to the points, such as photos taken during the trip, the reproducibility of the trip can be improved, allowing the user who traveled to enjoy the memories of the trip even more, and even those who did not travel can enjoy the feeling of having a simulated experience of the trip.

[0021] The points may be location information of locations selected by the user, such as sightseeing spots or places to stop for meals. The user may select locations such as planned sightseeing spots or restaurants in advance when creating a set route before the trip, or may select them during the trip. For example, the electronic device that creates the above-mentioned driving route may set points on the driving route based on the locations selected by the user.

[0022] If the system is equipped with a touch panel type electronic device, for example, it is preferable to display a map on the touch panel and provide buttons for the user to perform various input operations. The user may, for example, touch a selected location on the map or directly input an address. The electronic device may accept the input of location information and set that location as a point on the driving route. The display means may, for example, display the point in a way that indicates the position of the point on the map in an easily visible manner. Specifically, for example, it is preferable to display the point as a circular or rectangular mark colored in a different color from the driving route.

[0023] The information related to the points may be, for example, images or videos of the places the user visited or the food they ate at the points. It may also be, for example, comments by the user about the tourist spot that is the point. Alternatively, it may be video or audio recorded by the system at the points. Specifically, for example, the system may be equipped with an in-vehicle drive recorder, and the video and audio may be recorded by the drive recorder.

[0024] The display of information related to a point on the display means may be in a manner that makes the relationship with the point clear, for example, by extending a balloon from a mark indicating the point on a map and displaying the information or a thumbnail thereof in the balloon.

[0025] (3) The control means may cause the display means to display an icon that moves from the starting point to the end point of the travel route, and when the icon reaches the point, cause the display means to display information related to the point.

[0026] By displaying an icon that moves from the starting point to the end point of the travel route, and by displaying information related to the point when the icon reaches a point set on the travel route, the user's movements during the trip can be simulated, and events that occur during the trip can be reproduced along the route, allowing the user to enjoy more realistic travel memories.

[0027] The icon can be a simple shape such as a circle or triangle, or an illustration of a car or person, or a line that is colored a different color from the route and gradually extends from the starting point to the end point.

[0028] For example, the icon may move at a relatively fast speed where there are no points on the route, and slow down when moving near points. It may also be possible for the user to fast-forward or rewind the icon as needed.

[0029] Before the icon reaches the point, for example, the information related to the point may be hidden, or a thumbnail of the image or video may be displayed, or an illustration indicating the type of information, such as an image, video, or comment, may be displayed.

[0030] When the icon reaches a point, information related to that point should be displayed for a predetermined time, for example, about 10 seconds for an image, or about 20 seconds for a comment. For videos, the display time should be adjusted according to the video's playback time. While the information is being displayed, the icon's movement should be stopped, for example.

[0031] (4) The control means may cause the display means to display information regarding the recommended route calculated based on the starting point and end point input by the user, accept changes made by the user to the recommended route, and set the changed route as the set route for the user's planned travel.

[0032] A recommended route according to the starting point and end point input by the user is displayed on the display means, and Since a set route can be created by making changes to the recommended route, users can easily create plans before traveling, and in addition to enjoying memories after traveling, the system can provide greater convenience as a system that supports users in preparing to create memories. Furthermore, since the user can change the recommended route to make it a set route, flexible planning according to the user's experience, knowledge, and preferences is possible.

[0033] The system may include, for example, an electronic device with an application for creating a route set installed. For example, by using a PC as the electronic device, the user can create a thorough plan at home or elsewhere before setting off on a trip. Alternatively, the electronic device may be a portable electronic device such as a portable car navigation device or a smartphone. For example, the user can create a plan anywhere, such as on a train during their commute. Alternatively, the electronic device may be an in-vehicle electronic device such as a car navigation device. For example, the user can easily create a plan in the car before starting travel on the day of the trip.

[0034] The recommended route may be calculated according to a pre-stored algorithm based on the location information of the starting point and end point entered by the user. This allows a basic route to be easily created. Alternatively, a pre-recorded major tourist route may be used. Route creation may also be performed by accepting selections of not only the starting point and end point, but also intermediate points, key tourist spots, and gourmet food information that the user desires to eat. Information about the recommended route is not limited to information about the recommended route itself, but may also include information such as the names and characteristics of tourist spots on the recommended route.

[0035] In addition, for example, a route that has been previously created and stored may be called up as a recommended route according to the starting point and the end point, and the route may be edited to set it as a set route. The recommended route may be displayed on a map, for example, by tracing the recommended route with a thick colored line.

[0036] To accept a route change from the user, for example, in the case of a PC, the user can drag a part of the recommended route with a mouse to match the road they wish to take, thereby changing the via points and rerouting the recommended route. Alternatively, in the case of a smartphone or car navigation device that employs a touch panel, the user can change the recommended route by dragging a part of it with their finger.

[0037] (5) The control means may acquire information about a detour route created by the user along with information about the recommended route, and cause the display means to display the information, and may change the recommended route so that it passes through the detour route in accordance with the user's input.

[0038] The recommended route can be changed, for example, by using a detour route created by the user. That is, by displaying the detour route created by the user together with the recommended route on the display means and changing the recommended route so that it passes through the detour route according to the user's input, the user's knowledge and experience can be utilized more reliably and the set route can be created easily.

[0039] A detour route may be a route set by a user as a detour from another road. The detour route may be set as a detour from a commonly used road based on the user's personal experience and knowledge, such as the congestion status of surrounding roads and the ease of travel of the road. Note that a detour route may also include a route that is a shorter route than the recommended route. Information about the detour route may include not only the detour route itself, but also information about the detour route, such as user comments.

[0040] The detour route can be created by, for example, providing a detour route creation mode in the application that creates the set route. When using a PC, for example, the user can mouse over any road on the map and Alternatively, for example, when using a smartphone or car navigation device that employs a touch panel, the user can create a detour route by tracing any road on the map with their finger.

[0041] The created detour route can be registered with a name such as "Detour Route 1" and any user comments about the detour route. The detour route can be colored a different color from the recommended route on the map on the display screen so that it can be distinguished from the recommended route.

[0042] When a detour route is displayed on a map, the name of the detour route and user comments may also be displayed on the map, or the name and comments may be displayed when the user places the cursor over the detour route.

[0043] (6) The control means may cause the display means to display the recommended route that has been changed to pass through the detour route together with the recommended route before the change.

[0044] By displaying the recommended route that has been changed to pass through a detour route on the display means together with the recommended route before the change, the change in the route can be visually confirmed, making it easier to consider whether the change was appropriate. The recommended route before the change can be colored, for example, in a lighter or different color than the recommended route after the change, so that the user can easily recognize that it is the route before the change.

[0045] (7) The control means may cause the display means to display information about the recommended route as well as information about the avoidance points or avoidance routes created by the user.

[0046] By displaying the avoidance points or avoidance routes created by the user on the display means together with the recommended route, the set route can be created in a way that more reliably reflects the knowledge and experience of the user.

[0047] The avoidance points or avoidance routes may be set as points or roads that should be avoided based on the user's personal experience and knowledge, such as congestion, accidents, narrowness of roads, etc.

[0048] To create an avoidance point or an avoidance route, for example, an avoidance route creation mode may be provided in an application that creates a set route. The system may create an avoidance route by accepting user input. For example, the system may display a map on a display means, and the user may input by clicking any point on the map with a mouse or tracing a road with a mouse or the like, and the system may then accept the input and create an avoidance route. The created avoidance point or route may be registered with a name such as "Avoidance Point 1" or "Avoidance Route 2" automatically or based on user input. Furthermore, information about the avoidance route may include not only the avoidance route itself but also related information such as user comments about the route.

[0049] The avoidance points or routes may be colored in a different color from the recommended route and the detour route on the map on the display screen so that they can be distinguished from the recommended route and the detour route. The avoidance points may be displayed, for example, with an illustration such as a flag.

[0050] When an avoidance point or route is displayed on a map, the name of the avoidance point or route and a user comment may also be displayed on the map, or the name and comment may be displayed when the user places the cursor over the avoidance point or route.

[0051] (8) The system of the present invention displays information about a recommended route calculated based on a starting point and an end point input by a user on a display means, and accepts changes made by the user to the recommended route. It is preferable to further include a second control means for setting the changed route as a set route for the user's planned travel.

[0052] A recommended route according to the starting point and end point input by the user is displayed on the display means, and a set route can be created by making changes to the recommended route, so that the user can easily create a plan before traveling, and in addition to enjoying memories after the trip, the system can provide greater convenience as a system that supports the user in preparing to create memories. Furthermore, because the user can change the recommended route to make it a set route, flexible planning according to the user's experience, knowledge, and preferences is possible.

[0053] The recommended route may be calculated according to a pre-stored algorithm based on the location information of the starting point and end point entered by the user. Alternatively, a pre-recorded major tourist route may be used. The route may be created by accepting selections of not only the starting point and end point, but also intermediate points, key tourist spots, and gourmet food information that the user desires to eat. Information about the recommended route is not limited to information about the recommended route itself, but may also include information such as the names and characteristics of tourist spots on the recommended route.

[0054] In addition, for example, a route that has been created and stored previously can be called up as a recommended route according to the starting point and the end point, and the route can be edited to set it as a set route. The recommended route can be displayed, for example, on a map by tracing the recommended route with a thick colored line.

[0055] To accept a route change from the user, for example, in the case of a PC, the user can drag a part of the recommended route with a mouse to match the road they wish to take, thereby changing the via points and rerouting the recommended route. Alternatively, in the case of a smartphone or car navigation device that employs a touch panel, the user can change the recommended route by dragging a part of it with their finger.

[0056] The set route can be created using an electronic device separate from the device that displays the driving route and the set route, providing high flexibility. For example, the set route can be created using an electronic device such as a PC at home, and then the driving route and the set route can be displayed on a portable electronic device such as a smartphone or portable car navigation device while traveling.

[0057] For creating a set route, the system may be provided with a second control means separate from the control means for displaying information about the set route and the driving route for enjoying memories.Since the user can use different electronic devices depending on the situation, a simple and flexible system can be provided.

[0058] For example, a user can create a set route on a PC at home and then display information about the travel route and the set route in the car using an in-vehicle electronic device such as a car navigation system. Alternatively, the user can display information about the travel route and the set route on a portable electronic device such as a smartphone or portable car navigation system at a lodging facility at a travel destination.

[0059] Alternatively, for example, a user can create a planned route using a portable electronic device such as a smartphone or portable car navigation device while commuting, and then display information about the driving route and the planned route on a PC at home after the trip.

[0060] Data exchange between two electronic devices can be performed using a storage medium such as an SD card or USB memory. Alternatively, so-called cloud computing can be used. In other words, data created by one electronic device can be transferred to another electronic device on a network. The data may be transmitted to a server, and the server may then transmit the transmitted data to the other electronic device.

[0061] (9) The system of the present invention may preferably have a third control means for displaying information about a set route on a display means for route guidance while the user is driving, displaying the difference between the set route and the route the user is driving, and storing the route the user has driven in a storage means as information about the driving route.

[0062] By displaying the preset route set by the user before driving as a guide route on the display means while the user is driving, the user can proceed with the trip smoothly according to the pre-planned plan. However, the user often changes the route on the spot due to traffic congestion or being attracted by something that catches their eye, and this is also part of the fun of traveling. In such cases, by displaying the difference between the preset route and the route the user is driving, the user can experience the thrill of daring to deviate from the plan and take an adventure. At the same time, it can provide the user with a sense of security that they can always return to the preset route. Furthermore, by recording the route the user actually drives as the driving route, the user can prepare to enjoy the memories after the trip.

[0063] As a display mode of the difference between the set route and the route traveled by the user, for example, while the user is traveling along the set route, an icon may be displayed moving along the set route, similar to a general navigation display, and when the user deviates from the set route, the path the user is traveling from the point where he or she deviated may be colored in a color different from that of the set route.When the user returns to the set route, for example, the display may be restored to one in which the icon moves along the set route, with the portion of the route where the user deviated from the set route being highlighted.

[0064] The display of the set route and the recording of the traveled route may be performed by a third control means, separate from the control means that creates the set route before travel and the control means that displays the traveled route and information about the set route so that the traveled route can be enjoyed after travel. Different electronic devices can be used depending on the situation, providing a simple and highly flexible system.

[0065] For example, you can create a set route on your PC at home, and then use an in-vehicle electronic device such as a car navigation system to display the set route and record the traveled route.You can then display the recorded traveled route and the set route again on your PC at home to enjoy your memories.

[0066] For example, a user can create a set route on a PC at home, display the set route on an in-vehicle electronic device such as a car navigation system, and record the traveled route. Furthermore, a user can display the traveled route and set route at a lodging facility using a portable electronic device such as a smartphone and a projector. The user can enjoy the memories of the day during their trip.

[0067] Data exchange between two or three electronic devices can be performed using storage media such as SD cards or USB memory sticks. Alternatively, so-called cloud computing can be used. That is, data created by one electronic device can be sent to a server on a network, and the server can then send the data to the other electronic devices.

[0068] (10) The third control means may cause the display means to display information about the set route and information about a detour route created by the user while the user is traveling.

[0069] By displaying information about the detour route on the display means together with information about the set route, if there is a sudden traffic jam at the site, the user can refer to the detour route and change the driving route as needed. For example, the detour route created by the user may be one that was not adopted as part of the set route in the advance plan, but may be a second or third candidate depending on the local situation. Therefore, by displaying such a detour route along with the set route while driving, for example, if the driver encounters traffic congestion, the driver can easily change the plan by referring to the detour route.

[0070] (11) The third control means may create a point at any position on the travel route and register information related to the point.

[0071] By creating points at any location along your travel route and registering information related to those points, you can easily record various memories that occur along your travel route, making it a highly convenient tool for enjoying your trip.

[0072] Points can be created, for example, in response to user input, or automatically set at predetermined distances, such as every 10 km, or at predetermined time intervals, such as every hour, or automatically set in response to predetermined conditions, such as when the user deviates from the set route.

[0073] When a point is created by user input, information related to the point may include, for example, photos of tourist spots taken by the user or food eaten by the user, or user comments. Furthermore, when points are automatically set at predetermined distances, predetermined time intervals, or according to predetermined conditions, for example, video and audio recorded by a drive recorder installed in the vehicle may be extracted for each point and registered as information related to the point. For example, by registering conversations in the car when the user deviates from the set route, the user can clearly recall the reason for the deviation and enjoy the memories of the trip.

[0074] For example, if the system is equipped with a car navigation device operated by a touch panel, a user may touch a desired location on the displayed driving route to create a point at that location. Furthermore, once a point is created, a screen for registering information related to the point may be displayed. If the information is, for example, a user comment, a comment input screen may be displayed. If the information related to the point is, for example, an image or video, a screen for specifying the image or video to be uploaded may be displayed. If the information related to the point is, for example, video or audio recorded by a dashcam, a screen for specifying the extraction range of the video or audio may be displayed.

[0075] (12) The third control means may create a point at a position on the travel route that corresponds to the position information included in the information, and register the information as information related to the point.

[0076] For example, when an image is taken with a smartphone equipped with a GPS function, the image is tagged with location information known as a geotag. If the information to be registered includes such location information, a point can be created on the driving route at a position corresponding to the location information, and the information can be registered as information related to that point. This allows the user to easily register memories without having to specify a point.

[0077] For example, when a user takes an image with a smartphone, the geotagged image can be sent to an electronic device such as a car navigation system that records the driving route. The electronic device can then read the location information contained in the image, set a point at the corresponding location on the driving route, and register the image data as information related to the point.

[0078] (13) The third control means may create points at predetermined intervals on the travel route and register images or sounds captured at the points as information related to the points.

[0079] By creating points at predetermined intervals and storing images or sounds captured at the points in a storage means in association with the points, the user can easily record memories without making any special effort. The predetermined interval may be a predetermined time interval such as one hour, or a predetermined distance interval such as 10 km.

[0080] For example, images or audio can be captured by connecting an electronic device such as a car navigation device that records the driving route to a drive recorder installed in the vehicle, and each time a point is reached, the images seen from the car window and the audio from inside the car that are continuously recorded by the drive recorder can be extracted and stored as information related to the point.

[0081] When extracting video, for example, it may be extracted as a still image or as a video of about 3 minutes. When extracting audio, it is recommended to extract about 1 to 2 minutes so that you can understand what kind of conversation was taking place in the car.

[0082] In this way, by utilizing dashcams, which are often installed in vehicles in recent years in preparation for traffic accidents and other troubles, users can enjoy their travel memories by listening to images from the car window and conversations inside the car captured by the dashcam, even on rushed trips where they don't have time to take photos.

[0083] (14) While the user is driving, the control means may cause the display means to display information about the set route that was set before the user started driving for route guidance, display the difference between the set route and the route that the user is driving, and store information about the driving route that the user has driven in the storage means.

[0084] By displaying the preset route that the user set before traveling on the display means while the user is traveling, the user can travel smoothly according to their pre-planned plans. However, the user often changes the route they are traveling on the spot due to traffic congestion or something that catches their eye, and this is also part of the fun of traveling. In such cases, by displaying the difference between the preset route and the route the user is traveling, the user can experience the thrill of daring to deviate from the plan and take an adventure. At the same time, it gives the user a sense of security that they can always return to the preset route. Furthermore, by recording the route that the user actually travels as the traveled route, the user can prepare to enjoy their memories after the trip.

[0085] As a display mode of the difference between the set route and the route traveled by the user, for example, while the user is traveling along the set route, an icon may be displayed moving along the set route, similar to the display of a general navigation system, and when the user deviates from the set route, the path traveled by the user may be colored in a color different from that of the set route from the point where the user deviated.When the user returns to the set route, for example, the display may be restored to one in which the icon moves along the set route, with the portion of the route that deviated from the set route being highlighted.

[0086] It is preferable that the same control means is used to create a set route as advance preparation, display the set route while traveling, record the traveled route, and display the traveled route and set route. This makes it easy to enjoy memories after a trip and to prepare for a trip before and during a trip, all with a single electronic device, and provides an electronic device that is excellent in terms of hospitality to users.

[0087] For example, the system can be equipped with a portable navigation device or a smartphone with a navigation function, and a route can be created in advance at home or on a commuter train. The device can then be brought into the car during travel to display the route and record the traveled route. After the trip, you can take the device home and display the route you set and the route you took to enjoy your memories. Alternatively, you can bring a portable navigation device or smartphone to your accommodation during your trip, connect it to a projector, and hold a screening to enjoy your memories.

[0088] Alternatively, for example, by providing an in-vehicle electronic device such as a car navigation system, a set route can be created before starting to drive the car on the day of the trip, and the created set route can be displayed as is, while simultaneously recording the driving route.Then, for example, while taking a break at a parking area, the set route and the driving route up to that point can be displayed, allowing the traveler to reminisce and consider what route to take next.

[0089] (15) A program of the present invention is a program for realizing the function of the control means, the second control means, or the third control means in the system according to any one of (1) to (14) above. [Effects of the Invention]

[0090] According to the present invention, by displaying the travel route along with the set route set before the trip, for example, after the trip is over, the user can not only retrace the travel route but also recall and enjoy events related to changes from the original plan. This makes it possible to provide a system that is not only convenient but also has excellent entertainment value, allowing the user to enjoy memories of the trip.

[0092] [Electronic device configuration] [Basic configuration] [Portable car navigation device] FIG. 1 shows the appearance of an embodiment of a portable car navigation device (hereinafter simply referred to as "navigation device") 1 suitable as an electronic device that constitutes the system of the present invention, and FIG. 2 is a functional block diagram thereof. As shown in Fig. 1, the navigation device 1 comprises a portable device main body 2 that can be carried around, and a cradle 3 that serves as an attachment member for holding the device. When the device main body 2 is attached to the cradle 3, it functions as an in-vehicle navigation device, and when it is removed from the cradle 3, it functions as a portable navigation device (PND). In this embodiment, the device main body 2 is detachable from the cradle 3, and can be used by being placed on the dashboard of a vehicle together with the cradle 3, or by removing the device main body 2 from the cradle 3 and using it as a portable navigation device (PND).

[0093] The device main body 2 is detachably attached to the cradle 3. The device main body 2 includes a flat, rectangular case main body 4. A display unit 5 is disposed on the front of the case main body 4. A touch panel 8 is provided on the display unit 5 to detect which part of the display unit 5 is touched, and warning lamps 9 are provided on both sides of the front. The cradle 3 includes a cradle main body 6 that holds the device main body 2 and a base 7 that positions the cradle main body 6 in any orientation at a predetermined location in the vehicle (e.g., the dashboard). The base 7 is attached to the dashboard or other surface by a suction cup on its bottom. The base 7 and the cradle main body 6 are connected via a connecting mechanism such as a ball joint so that they can rotate within a predetermined angular range. Because of the ball joint, the base 7 and the cradle main body 6 can rotate relative to each other within any angular range in three dimensions and maintain that position at any angular position due to frictional resistance at the joint. Therefore, the device main body 2 attached to the cradle main body 6 can also be positioned in any orientation on the dashboard.

[0094] Furthermore, one side of the case body 4 is provided with an SD memory card slot 21, into which an SD memory card 22 having map data and the like recorded therein can be inserted. This SD memory card slot 21 includes a memory card reader / writer that reads and writes information from and to the inserted SD memory card 22. Also, a DC jack 10 is provided on the side of the case body 4 on which the SD memory card slot 21 is provided. The DC jack 10 is for connecting a cigarette lighter plug cord (not shown), and can be connected to a vehicle's cigarette lighter socket via the cigarette lighter plug cord to receive power.

[0095] Meanwhile, a power switch and a USB terminal 23 are provided on the side opposite the SD memory card slot 21. The navigation device 1 can be connected to a personal computer via the USB terminal 23 to perform software application updates, etc. Furthermore, by connecting the navigation device 1 via the USB terminal 23 to a mobile projector 80 shown in Fig. 11, the output image can be projected onto a screen, wall, etc.

[0096] The following devices and components are arranged inside the case body 4. Specifically, a microwave receiver 11 is arranged inside the rear side of the case body 4. The microwave receiver 11 receives microwaves of a predetermined frequency band, and when it receives microwaves of the set frequency band, it detects the signal level of the received microwaves. Specifically, it uses the RSSI voltage, which is the signal level and corresponds to the field strength. The predetermined frequency band is a frequency band that includes the frequency of microwaves emitted from, for example, a vehicle speed measurement device.

[0097] A GPS receiver 12 that receives GPS signals and determines the current location is disposed inside the top surface of the case body 4. An infrared communication device 14 is disposed inside the front surface of the case body 4. The infrared communication device 14 transmits and receives data to and from a communication device that has a built-in infrared communication device, such as a smartphone 15. A speaker 20 is also disposed inside the case body 4.

[0098] Furthermore, the device of this embodiment is equipped with a wireless receiver 13 and a remote control receiver 16. The wireless receiver 13 receives incoming wireless signals of a predetermined frequency. The remote control receiver 16 performs data communication with a remote control (portable device: slave device) 17 and performs various settings for the device. The wireless receiver 13 receives incoming wireless signals of a predetermined frequency band. This predetermined frequency can be, for example, a wireless frequency band used when an emergency vehicle notifies a base station of its own location.

[0099] The navigation device 1 of this embodiment has a navigation function, a set route reproduction function and a travel route recording function, which will be described later, as well as a target notification function as a target notification device that notifies the user of targets such as vehicle speed measurement devices and other traffic monitoring points that exist in the vicinity. These functions are stored in the EEPROM of the control unit 18 as programs that are executed by a computer included in the control unit 18, and are realized by the computer executing these programs.

[0100] That is, the control unit 18 executes predetermined processing based on information input from the above-mentioned various input devices (GPS receiver 12, microwave receiver 11, wireless receiver 13, touch panel 8, infrared communication device 14, remote control receiver 16, SD memory card slot unit 21, USB terminal 23, etc.), and outputs predetermined information, warnings, and messages using output devices (display unit 5, warning lamp 9, speaker 20, infrared communication device 14, SD memory card slot unit 21, USB terminal 23, etc.). This predetermined processing is for executing each of the above-mentioned functions, and accesses the database 19 and the SD memory card 22 as necessary.

[0101] Here, database 19 can be realized by a non-volatile memory (e.g., EEPROM) inside the microcomputer of control unit 18 or externally attached to the microcomputer. At the time of shipment, certain landmarks, maps, and other information necessary for implementing each function are registered in database 19, and data on landmarks added later can be updated through a predetermined process. This updating process can be performed, for example, by inserting an SD memory card 22 storing the additional data into SD memory card slot unit 21 and transferring the data from the SD memory card 22 to database 19. This data updating can also be performed using infrared communication device 14 or a personal computer or other external device connected via USB terminal 23.

[0102] The control unit 18 for realizing the target notification function operates as follows. That is, when the microwave receiver 11 receives a desired microwave, the control unit 18 outputs a predetermined alarm. This alarm can be a buzzer using the speaker 20, a voice output to notify reception of microwaves (detection by a vehicle speed measurement device, etc.), or a message output in the form of text or an image using the display unit 5.

[0103] Furthermore, when the wireless receiver 13 receives a desired radio signal, the control unit 18 outputs a predetermined alarm. This alarm may be a buzzer using the speaker 20, a voice output to notify the reception of microwaves (such as the approach of an emergency vehicle), or a message in the form of text or an image using the display unit 5. It is preferable that the alarm accompanying this radio signal reception and the alarm accompanying the microwave signal reception be in different forms.

[0104] Furthermore, the control unit 18 outputs a predetermined alarm when the current position detected by the GPS receiver 12 and the position of a target such as a traffic monitoring point stored in the database 19 are in a predetermined positional relationship. For this reason, the database 19 contains information about the target to be detected (target position information including longitude and latitude, target type information, etc.), traffic safety information for driving more carefully and safely such as accident-prone areas and traffic control information, and various information useful for driving such as landmarks. Each piece of information is classified into specific information types (target type, traffic The information is registered in association with location information (such as the type of enforcement, accident-prone areas, and names of landmarks).

[0105] The distance to the target when issuing the warning can be changed depending on the type of target. As described above, warning modes include audio warnings using the speaker 20 and warnings using the display unit 5. FIG. 3 shows an example of a warning using the display unit 5. In this embodiment, since the device is a navigation device and has map data as described below, the control unit 18 has the function of reading road network information around the current location and displaying a map around the current location on the display unit 5 as a basic screen. Then, the display unit 5 displays a warning screen 70 superimposed on the currently displayed screen (here, the map around the current location). FIG. 3 shows an example of the warning screen 70 displayed when the distance between the current location and an LH system, a type of speed measurement device that is a traffic monitoring point, becomes 500 m while the map 50 is displayed. Furthermore, a warning voice indicating the type of warning and the distance, such as "LH system 500 m ahead," is output from the speaker 20.

[0106] Meanwhile, the control unit 18 for realizing the navigation function operates as follows. First, the database 19 stores road network information for navigation. The information for navigation stored in this database 19 may contain all information for the entire country at the time of shipment, or map data and the like may be provided for each region stored in an SD memory card 22, and the user may prepare an SD memory card 22 containing the necessary map data and insert it into the SD memory card slot unit 21 for use. The map data and the like stored in the SD memory card 22 may be transferred to and stored in the database 19, or the control unit 18 may access the SD memory card 22 and read and use the data from there.

[0107] The control unit 18 has the function of reading road network information around the current location from the database 19 and displaying a map of the area around the current location on the display unit 5. The control unit 18 can use this road network information to search for a route from one location to another. The database 19 also includes a telephone number database that stores telephone numbers in association with the location information and names of homes, businesses, facilities, etc. associated with those telephone numbers, and an address database that stores addresses in association with the location information of those addresses. The database 19 also stores the location information of traffic monitoring points such as speed measurement devices, along with their types.

[0108] The control unit 18 also has a function of performing general navigation device processing. That is, the control unit 18 constantly displays a map of the area around the current location on the display unit 5 and displays a destination setting button. The control unit 18 performs a destination setting process when it detects a touch on the touch panel 8 at a position corresponding to the display position of the destination setting button. In the destination setting process, the control unit 18 displays a destination setting menu on the display unit 5 and prompts the user to select a destination setting method. The destination setting menu has a phone number search button and an address search button that prompt the user to select a destination setting method. When it detects that the phone number search button has been touched, it displays a phone number input screen and obtains location information corresponding to the entered phone number from the database 19. When it detects that the address search button has been touched, it displays an address selection input screen and obtains location information corresponding to the entered address from the database 19. The obtained location information is then set as the location information of the destination, and a recommended route from the current location to the destination is calculated based on road network information stored in the database 19. A known method, such as the Dijkstra algorithm, can be used to calculate this recommended route.

[0109] Then, the control unit 18 displays the calculated recommended route together with a map of the surrounding area. For example, as shown in FIG. 4, a route 53 from a current position 51 to a destination 52 is displayed as the recommended route in a predetermined color (for example, red). This is similar to a general navigation system. In this embodiment, the control unit 18 compares the position information on the route 53 with the position information of landmarks such as traffic monitoring points stored in the database 19, and displays the positions of the traffic monitoring points and the like located on the route 53. Note that the provision of information for safe driving along the route 53 may be limited to traffic monitoring points among the various landmarks stored in the database 19.

[0110] As a result, for example, as shown in FIG. 4, a speech bubble is displayed from a position on the road, and the type of traffic monitoring point at that position stored in the database 19 is displayed in the speech bubble. For example, FIG. 4(a) is an example of the display of a warning point search screen, showing traffic monitoring points 55a to 55f. Traffic monitoring point 55a displays the letter "N" in its speech bubble, indicating an N system. Traffic monitoring points 55b, 55c, and 55e display the letters "LH" in their speech bubbles, indicating an LH system. Traffic monitoring point 55d displays the letter "loop," indicating a loop coil, in its speech bubble. Traffic monitoring point 55f displays the letter "H," indicating an H system, in its speech bubble. When the touch panel 8 detects a touch at a position in the simplified display state where text is displayed in the speech bubble, the simplified display is switched to a detailed display, as shown in FIG. 4(b). The detailed display displays the warning screen shown in FIG. 3 in the speech bubble.

[0111] As shown in FIG. 4(a), a traffic monitoring point type designation section 56 is displayed in the lower right corner of the display unit 5. The traffic monitoring point type designation section 56 is a section that displays buttons listing the types of traffic monitoring points present on the route 53. In the example of FIG. 4(a), an "N" type button 57a ​​indicating the N system of traffic monitoring point 55a, an "LH" type button 57b indicating the LH system of traffic monitoring points 55b, 55c, and 55e, a "Loop" type button 57c indicating the loop coil of traffic monitoring point 55d, and an "H" type button 57d indicating the H system of traffic monitoring point 55f are displayed. When the control unit 18 detects a touch on the type button display section on the touch panel 8, it highlights the touched type button and switches the display mode of the traffic monitoring point corresponding to the touched type button from simple display to detailed display, or from detailed display to simple display.

[0112] 5 shows the appearance of a personal computer (hereinafter referred to as a PC) 30 suitable as another electronic device constituting the system of the present invention, and FIG. 6 is a functional block diagram thereof. Here, a desktop PC is shown as an example of PC 30. PC 30 includes at least a control unit 31, a storage unit 32, a display unit 33, an audio output unit 34, and an input unit 35.

[0113] The control unit 31 includes a CPU that is composed of a microprocessor and its peripheral circuits. The storage unit 32 includes a ROM, RAM, HDD, etc. An OS (Operating System) and various application programs are installed in the storage unit 32. The CPU of the control unit 31 controls the entire PC 30 by executing the OS and each application program installed in the storage unit 32. The CPU, ROM, RAM, and HDD are installed inside the housing 40.

[0114] The display unit 33 includes a display device 36 such as a liquid crystal panel or an organic EL panel, and displays image information. The audio output unit 34 includes a speaker or an earphone jack, and outputs audio information. The input unit 35 includes an input device such as a keyboard 37 or a mouse 38, and accepts input operations from the user.

[0115] The PC 30 also has an SD memory card slot 39, into which an SD memory card 22 can be inserted, in which a route information file including data on set routes and detour routes is recorded. The SD memory card slot unit 39 includes a memory card reader / writer that reads and writes information from and to the inserted SD memory card 22.

[0116] In this embodiment, an application program for route setting and editing is pre-installed in the storage unit 32. The storage unit 32 also stores information necessary for route editing, such as map information, facility information, and input history. The CPU of the control unit 31 executes the application program for route setting and editing, and reads and writes information stored in the storage unit 32, thereby realizing the route setting and editing function.

[0117] It should be noted that the desktop PC is merely an example, and various types of PCs such as notebook PCs and tablet PCs can be used.

[0118] As shown in FIG. 7 , the functions of the system of this embodiment can be realized by exchanging a route information file between the two electronic devices. For example, a route information file is created and edited in one of the electronic devices, and the route information file is stored, for example, in an SD memory card 22 and read by the other electronic device. Alternatively, for example, a route information file is sent from one of the electronic devices to a smartphone 60 via wireless communication, and then sent from the smartphone 60 to the other electronic device. The system of this embodiment executes a route setting and editing function, a set route reproduction function, a detour route search function, a driving route recording function, and a driving route reproduction function. An application program for realizing each function is installed in each electronic device, and the control unit of each electronic device executes the application program to realize each function.

[0119] For example, before a trip, a user sets or edits a planned travel route (route) for a vehicle as desired on PC 30 at home and saves it as a route information file. This route information file is saved in SD memory card 22 and read by navigation device 1. Alternatively, it is sent to smartphone 60 and then sent from smartphone 60 to navigation device 1. By reading the set route from the route information file in navigation device 1, route guidance along the route set by the user can be provided when traveling in a vehicle.

[0120] The navigation device 1 also records the route actually traveled by the vehicle and saves it as a route information file together with the set route. Images captured by a drive recorder during the trip and photos taken by the user with a smartphone camera can also be recorded as information related to the traveled route. After the trip, the route information file can be loaded again into the PC 30 at home to recreate the traveled route and the set route, allowing the user to enjoy memories of the trip. Each function of the system of this embodiment described above will now be described in detail.

[0121] [Route setting editing function] Route setting editing on the PC 30 is performed by the control unit 31 starting up a route setting editing application, displaying a route setting editing screen 71 on the display unit 33, and receiving user input via the input unit 35. FIGS. 8 to 11 show display examples of the route setting editing screen 71. The route setting editing function performs at least two operations: a new route creation operation and a route change operation for an already created route information file.

[0122] (Create a new route) When the control unit 31 receives a selection input for creating a new route from the user, the control unit 31 displays input fields for the starting point, destination, and search conditions on the display unit 33. As input fields for search conditions, it is preferable to provide, for example, input fields for intermediate points, tourist destinations, and required time, and a selection field for free general roads or toll expressways. When the control unit 31 receives a user's input via the input unit 35, it automatically performs a route search according to the algorithm of the application program and predicts the search results. This is displayed as a recommended route R1 on the route setting and editing screen 71. As shown in Fig. 8, the recommended route R1 is displayed as a thick colored line tracing the travel route on the map including the starting point and the destination.

[0123] If the user is satisfied with the recommended route R1, he or she saves the created route. The control unit 31 saves the recommended route R1 as a set route in a route information file. The control unit 31 saves the route information file in the storage unit 32 of the PC 30.

[0124] Users can also create any route manually from the beginning. In this case, select "Manual Route Creation Mode" when selecting and entering information to create a new route. In manual route creation mode, users first input a starting point and destination to search, and a map screen containing the two points is displayed. The user then sets the route by tracing the route between the two points on the map with the mouse cursor. Alternatively, users can set the starting point as the point where they place the mouse cursor and click, and the destination as the point where they release the mouse cursor, without searching for the starting point and destination. This mode is good for creating routes that are not often guided by navigation, such as shortcuts.

[0125] (Route Edit) The system is provided with a route editing function that allows the user to change the recommended route R1 displayed on the route setting editing screen 71 to create a route unique to the user.

[0126] To edit the route, the user drags the travel path line of the recommended route R1 displayed on the map with the mouse cursor and drops it onto the road they wish to pass through. The control unit 31 then searches again for a route to the destination that passes through the specified road.

[0127] When saving the edited route information, the control unit 31 compares it with the route information before editing, calculates the difference between the changed route, and saves the route information and the search conditions set by the user in a file. This allows the route edited by the user to be displayed as the recommended route R1 the next time the user searches for a route using the same search conditions.

[0128] In addition to the recommended route R1, the route setting and editing screen 71 can display information useful for the user's route editing work. As an example, as shown in FIG. 8, pre-registered detour routes R2 and R3 and via point P1 can be displayed. Multiple detour route information files can be loaded and displayed simultaneously on the same map. The recommended route R1 and the travel route lines of the detour routes R2 and R3 are displayed in different colors.

[0129] When the user inputs an address, telephone number, etc. on the route setting edit screen 71, the corresponding location on the map is displayed as a via point P1. The via point P1 is indicated by, for example, an icon resembling a flag. The via point P1 can be registered with a name.

[0130] By displaying the recommended route R1 together with the detour routes R2 and R3 and the via point P1, it is possible to see at a glance the places you want to pass through or shortcuts along the route to your destination, making editing easier.

[0131] When the user drags the recommended route R1 and drops it onto the via point P1 or the detour routes R2, R3, the control unit 31 searches again for a route that passes through the via point P1 or the detour routes R2, R3.

[0132] When the user wishes to change the recommended route R1 so that it passes through a detour route R2 displayed on the map, the user presses the button at the point where the user wishes to change the recommended route R1, as shown in FIG. The user drags the cursor to move it to the starting position of the detour route R2 and drops it. The control unit 31 searches for a route again so that the user moves from the dragged point on the recommended route R1 to the starting position of the detour route R2. Furthermore, since the end of the detour route R2 does not reach the destination, an automatic route search is performed from the end position of the detour route R2 to the destination, and the remaining travel route is created.

[0133] As a result, the changed recommended route R1 is displayed on the route setting edit screen 71, as shown in Figure 10. If the user is not satisfied with the changed route, he or she can drag it again to return to the route before the change. Alternatively, if the user wants to change the recommended route R1 to take another road halfway through the detour route R2, he or she can drag and drop it at the point where the change is desired.

[0134] To register such detour routes R2 and R3, the user selects the "Detour Route Creation Mode" on the new route creation screen. In the detour route creation mode, the user creates a route by tracing a travel route line on the map with a mouse or the like.

[0135] The created detour routes R2 and R3 can be registered with any name, such as "Detour Route 1." In addition, users can also register comments about detour routes R2 and R3, such as "Recommended for weekdays." If user comments have been registered, they will also be displayed on the map when the detour route information file is loaded.

[0136] The created detour routes R2 and R3 can be saved together with the set route R1 as a single route information file. This allows the detour routes R2 and R3 to be displayed when reproducing the set route in the navigation device 1 (described later) and used as a means of avoiding traffic congestion.

[0137] Alternatively, the detour routes R2 and R3 can be saved as individual route information files. By saving the created route information files for the detour routes R2 and R3 on the SD card 22 and loading them into the smartphone 60, users can easily share the detour routes R2 and R3 with each other. Furthermore, by using a dedicated application, the contents of the route information file can be reproduced as map information on the smartphone 60, for example, and can be checked.

[0138] Route editing can also be performed on the portable navigation device 1 by installing a similar application. Because the portable navigation device 1 is portable, it can be connected to a mobile projector (hereinafter simply referred to as a "projector") 80, as shown in FIG. 11, for example. The route setting and editing screen 71 is displayed on a wall or screen via the projector 80, allowing the user to edit the route as desired on the navigation device 1 in the same way as operating a notebook PC. Displaying a map on the projector 80 makes it easier to see than the small screen of the navigation device 1, allowing multiple people, such as family and friends, to discuss and decide on a travel route while traveling. Rather than simply displaying a map, the route can be displayed in 3D, allowing the user to virtually travel from the starting point to the destination and check the created route.

[0139] Because the route setting and editing screen 71 is displayed on a screen or wall via the projector 80, remote control buttons for setting operations may be displayed on the screen of the navigation device 1 so that the user can operate it via a touch panel. For example, a button 72 for moving the cursor corresponding to a mouse pad may be displayed at the top of the screen. A left mouse button 73 may be displayed at the bottom left of the screen, a right mouse button 74 may be displayed at the bottom right of the screen, and a button 75 for moving the display position of the map displayed via the projector 80 may be displayed at the bottom center of the screen.

[0140] [Set route reproduction function] The navigation device 1 of this embodiment has a mode in which a route is automatically searched for by inputting a normal destination, and a mode in which route guidance is performed by reading a set route edited by the user on the PC 30. For convenience, the former mode is called the navigation mode, and the latter mode is called the user mode. Here, the set route reproduction function when the navigation device 1 operates in the user mode will be described.

[0141] The route search algorithms of the navigation device 1 and the PC 30 are assumed to be substantially the same. Therefore, the set route R4 edited on the PC 30 can be reproduced on the route reproduction screen 77 of the navigation device 1 with substantially the same travel route line, as shown in FIG. 12. The user can travel along the set route R4 reproduced on the navigation device 1.

[0142] [Detour route search function] As a means of avoiding traffic congestion encountered while traveling on the set route R4, a detour route can be displayed on the route reproduction screen 77 of the navigation device 1. The detour route can be saved in the same route information file as the set route R4 when editing the route on the PC 30 as described above, or can be saved as a separate route information file. When this detour route is loaded into the navigation device 1, the navigation device 1 registers the detour route in the database. When the user invokes a registered detour route, the control unit of the navigation device 1 displays detour routes near the current location and also displays route change examples that would result from using that detour route. If there are multiple detour routes, a route change example that takes the detour route closest to the current location is displayed.

[0143] For example, as shown in Fig. 12, if a user is traveling along set route R4 and traffic congestion information J is displayed along set route R4, the user performs a detour operation to avoid the traffic congestion. When the control unit 18 receives a detour operation input, it reads out and displays two detour routes, detour route R2 and detour route R3, which are close to the current location. As shown in Fig. 13, the control unit 18 reroutes the vehicle to the destination via detour route R2, which is closer to set route R4 out of the two detour routes R2 and R3.

[0144] If the user wishes to select another detour route R3, the user performs an operation to change the detour route, and the navigation device 1 reroutes the vehicle to the destination via the second closest detour route R3.

[0145] [Route recording function] In user mode, the system reproduces the set route R4 and simultaneously records the route the user actually travels while driving the vehicle. The travel route is created by acquiring position information from the GPS receiver 12. For example, when the vehicle is traveling through a tunnel and the GPS receiver 12 cannot acquire position information from a satellite, the system calculates the vehicle's position using sensors installed in the vehicle, such as a direction sensor, distance sensor, or gyro sensor, and creates the travel route. The travel route can be saved as a route information file together with the set route R4.

[0146] As shown in FIG. 14, the control unit 18 can record the travel route R5 and simultaneously display it on the display unit 5. The travel route R5 may differ from the set route R4 created in advance due to route changes to avoid congestion or the user's own ideas. To clearly distinguish the difference between the travel route R5 and the set route R4, the travel route R5 should be displayed in a different color from the set route R4. When the user is traveling according to the set route R4, the travel route R5 overlaps with the set route R4. On the other hand, if the user deviates from the set route R4 midway and changes the route to take the detour route R2, the travel route R5 will be different from the set route R4 from the point where the route was changed. Branches off from route R4.

[0147] [Related information recording function] In user mode, a function is also provided for associating various information with the travel route R5. The information may be, for example, images, audio, or video. For example, images and audio recorded by a drive recorder installed in the vehicle can be associated. Also, for example, images captured by the user using a smartphone 60 or the like can be associated. The information is associated by reading the location information contained in the information, creating points P2 to P6 at positions on the travel route R5 that are the same as or close to the positions indicated by the location information, and associating the points with the information. This information association process may be performed automatically by creating a program in advance, or it may be performed manually by accepting user input.

[0148] As an example of automatically associating information, the control unit 18 periodically acquires and stores image and audio information from a drive recorder installed in the vehicle, for example, every 30 minutes. The control unit 18 reads the location information contained in the information and creates a point on the driving route R5 at a position corresponding to the position indicated by the location information. The control unit 18 writes the file names of the acquired image and audio information as associated information at the created point, and saves the file as a route information file.

[0149] As an example of manually associating information, the control unit 18 acquires and saves an image captured by a user using, for example, the smartphone 60. For example, while traveling in a vehicle, the user stops at a tourist spot and captures the scenery using the camera of the smartphone 60. If the smartphone 60 is equipped with a GPS sensor, location information known as a geotag can be added to the captured image information. The user saves the image information in the SD card 22 and reads it into the navigation device 1 or transmits it to the navigation device 1 via wireless communication. The control unit 18 saves the image information, reads the geotag, and creates a point on the traveling route R5 at a position closest to the geotag. The control unit 18 writes the file name of the image information read in to the created point and saves it as a route information file.

[0150] [Route replay function] The PC 30 displays the recorded driving route R5 and its related information on a map together with the set route R4. An application program for reproducing a driving route is pre-installed in the storage unit 32. For example, after a trip, the user can save a route information file on the SD memory card 22, take it home, and read the SD memory card 22 into the PC 30 to reproduce the actual driving route R5 on a map and enjoy memories of the trip.

[0151] An example of the route reproduction screen 77 is shown in Figure 15. The traveled route R5 is displayed together with a set route R4 that was created in advance. The traveled route R5 and the set route R4 are displayed in different colors. Points P2 to P6, for which related information is recorded, are displayed as star-shaped icons on the traveled route R5.

[0152] When the driving route reproduction operation is performed, a triangular icon i is displayed moving from the starting point of the driving route R5 toward the end point. When the triangular icon i reaches each of the points P2 to P6, it stops moving. The control unit 18 reads out the information associated with that point, and if it is image information, displays it on the display unit 5, and if it is audio information, outputs it from the speaker 20. The image information is displayed for, for example, 10 seconds. After displaying, the screen returns to the map screen, and the icon is moved again toward the end point.

[0153] In addition, just like route setting and editing, the reproduction of the driving route R5 can also be done using a portable navigation device. This can be done with the portable navigation device 1. As shown in FIG. 11, by connecting the portable navigation device 1 to a projector 80 and displaying a route reproduction screen 77 on a wall or screen, it is possible to enjoy memories of the trip on a large, realistic screen. Because the route reproduction screen 77 is displayed on a screen or wall via the projector 80, remote control buttons as shown in FIG. 11 may be displayed on the screen of the navigation device 1 so that the user can operate it via a touch panel. For example, a button 72 for moving the cursor corresponding to a mouse pad may be displayed at the top of the screen. A left mouse button 73 may be displayed at the bottom left of the screen, a right mouse button 74 may be displayed at the bottom right of the screen, and a button 75 for moving the display position of the map displayed via the projector 80 may be displayed at the bottom center of the screen.

[0154] [effect] The above-described embodiment has the following effects. (A) The control unit 31 of the PC 30 acquires information about the user's driving route R5 and displays it on the display unit 5 along with information about the set route R4 set before the user's trip. For example, when traveling by car, a user may plan their driving route in advance to efficiently visit their desired tourist spots. However, when actually setting off on a trip, they often find themselves changing their driving route on the spot because the planned road is congested or they are attracted by something they see. Such flexible changes to plans are one of the joys of traveling, and when looking back on it later, they are remembered as one of the fun events of the trip. For example, after the trip is over, the user can enjoy real-life memories of the trip by displaying and retracing the route they traveled. At the same time, by displaying the route they had planned to travel, they can vividly recall the events related to the plan change. In other words, a highly convenient system can be provided that supports users in enjoying their travel memories.

[0155] You can also consider whether the change in plan was successful, whether you should take the route you missed due to the change in plan, and discuss this with your companions, which can be useful for planning your next trip.

[0156] The information regarding the travel route R5 may include, in addition to the travel route R5 itself traveled by the user in a car, information regarding, for example, images taken or audio recorded along the travel route R5. The travel route may be, for example, a route traveled by the user driving a vehicle such as a car, motorcycle, or bicycle. Alternatively, it may be a route traveled or walked on foot by the user while jogging, hiking, trekking, or the like. The travel route R4 may be created, for example, by acquiring information measuring the vehicle's position and direction of travel using the GPS receiver 12 of the navigation device 1. The display unit 5 may display the created travel route R5 by coloring the roads on a map to make them stand out. The device may be equipped with an electronic device equipped with a GPS, such as a smartphone 60, and the electronic device may acquire information measuring the user's or vehicle's position and direction of travel to create the travel route information.

[0157] The information regarding the set route R4 may be, for example, a set route set as a travel plan before the user sets off and related information. It may include not only the set route itself but also, for example, information about tourist spots and traffic information along the set route. The set route R4 can be easily created using an application that calculates a recommended route R1 based on input of various conditions, such as the starting point, end point, intermediate destinations, and travel time. For example, this application may be installed on the PC 30 or the navigation device 1. The application may calculate the recommended route R1 based on user input and create the set route R4 according to the user's selection. The set route R4 may be displayed, for example, by coloring roads on a map in a conspicuous color, preferably a different color from the travel route R5, to make it easier to distinguish.

[0158] (B) The control unit 31, for example, detects points P2, P3, and P4 set on the travel route R5. By displaying P5, P6 and related information on the display unit 33, the reproducibility of the trip can be improved, allowing users who have traveled to enjoy their memories of the trip even more, and even those who did not accompany the trip can enjoy the feeling of having a simulated experience of the trip.

[0159] Points P2, P3, P4, P5, and P6 may be location information of locations selected by the user, such as sightseeing spots or places where the user stopped for meals. The user may select planned sightseeing spots, restaurants, and other locations in advance, for example, when creating the set route R4 before the trip, or may select these locations during the trip. For example, the navigation device 1 may set points on the travel route R5 based on the locations selected by the user.

[0160] If the system includes a touch panel electronic device, for example, a map may be displayed on the touch panel, and buttons for the user to perform various input operations may be provided. The user may, for example, touch a selected location on the map or directly input an address. The electronic device may accept the input of location information and set that location as a point on the driving route. The display of points P2, P3, P4, P5, and P6 may, for example, indicate the positions of points P2, P3, P4, P5, and P6 on the map in an easily visible form such as a star. Specifically, for example, the points may be displayed as circular or rectangular marks colored in a different color from the driving route R5.

[0161] The related information for points P2, P3, P4, P5, and P6 may be, for example, images or videos of the places the user visited or the food they ate at points P2, P3, P4, P5, and P6. It may also be, for example, user comments about the tourist spots that are the points. Alternatively, it may be video or audio recorded by the system at points P2, P3, P4, P5, and P6. Specifically, for example, the system may be equipped with an in-vehicle drive recorder, and the video and audio may be recorded by the drive recorder.

[0162] It is preferable that the information relating to points P2, P3, P4, P5, and P6 on the display unit 33 is displayed in a manner that makes it possible to understand the relationship with points P2, P3, P4, P5, and P6. For example, on a map, it is preferable to extend speech bubbles from marks indicating points P2, P3, P4, P5, and P6, and display the information or a thumbnail thereof in the speech bubbles.

[0163] (C) The control unit 31 causes the display unit 33 to display an icon i moving from the starting point to the end point of the travel route R5, and when the icon i reaches each of points P2 to P6 on the travel route R5, causes the display unit 33 to display related information for points P2, P3, P4, P5, and P6, thereby simulating the user's movements during the trip and further recreating events that occurred during the trip along the route, allowing the user to enjoy more realistic travel memories.

[0164] The icon i may be a simple shape such as a circle or triangle, or an illustration of a car or person, or a line that is colored a different color from the route and gradually extends from the starting point to the end point.

[0165] The icon i may move at a relatively fast speed where there are no points on the route R5, and slow down when moving near points. It may also be possible to fast-forward or rewind the icon i as needed by user operation.

[0166] Before the icon i reaches points P2, P3, P4, P5, and P6, the information related to points P2, P3, P4, P5, and P6 may be hidden. Alternatively, thumbnails of the images and videos that represent the information may be displayed. Alternatively, illustrations indicating the type of information, such as images, videos, and comments, may be displayed.

[0167] When icon i reaches points P2, P3, P4, P5, and P6, information related to those points P2, P3, P4, P5, and P6 may be displayed for a predetermined time, such as about 10 seconds for images or about 20 seconds for comments. For videos, the information may be displayed according to the playback time of the video. While the information is being displayed, for example, the movement of icon i may be stopped.

[0168] (D) The control unit 31 of the PC 30 may display on the display unit 33 information about the recommended route R1 calculated based on the starting point and end point input by the user, accept changes made by the user to the recommended route R1, and set the changed route as the set route R4 of the user's planned travel.

[0169] Users can easily create plans before their trip, and in addition to enjoying their memories after the trip, the system provides greater convenience as it supports users in preparing to create memories. Furthermore, users can change the recommended route R1 to set a preset route R4, enabling flexible planning based on the user's experience, knowledge, and preferences.

[0170] By installing an application for creating the set route R4 on the PC 30 at the user's home, the user can create a detailed plan at home or elsewhere with ample time before leaving for the trip.

[0171] The recommended route R1 may be calculated according to a pre-stored algorithm based on the location information of the starting point and end point entered by the user. This allows a basic route to be easily created. Alternatively, a pre-recorded major tourist route may be used. The route may be created by accepting selections of not only the starting point and end point, but also intermediate points, key tourist spots, and gourmet food information that the user desires to eat. The information about the recommended route R1 is not limited to information about the recommended route R1 itself, but may also include information such as the names and characteristics of tourist spots on the recommended route R1.

[0172] Alternatively, for example, a previously created and stored route may be called up as a recommended route R1 according to the starting point and end point, and the route may be edited to create a set route R4. The recommended route R1 may be displayed, for example, on a map by tracing the recommended route with a thick colored line.

[0173] To accept a route change from the user, for example, the user may drag a part of the recommended route R1 with the mouse on PC 30 to match the path they wish to take, thereby changing the via points and rerouting the recommended route R1.

[0174] (E) The control unit 31 of the PC 30 may acquire information about the recommended route R1 as well as information about the detour routes R2 and R3 created by the user, and display the information on the display unit 33. The recommended route R1 may be changed to pass through the detour route R2 or R3 in accordance with the user's input. This makes it possible to more reliably utilize the user's knowledge and experience and easily create the set route R4.

[0175] The detour routes R2 and R3 may be routes set by the user as detours from other roads. The detour routes R2 and R3 may be set as detours from commonly used roads based on the user's personal experience and knowledge, such as the congestion status of surrounding roads and the ease of travel of the roads. Note that the detour routes R2 and R3 may also include routes that are shorter than the recommended route R1. Information about the detour routes R2 and R3 may include not only the detour routes R2 and R3 themselves, but also information about the detour routes R2 and R3, such as user comments.

[0176] The detour routes R2 and R3 may be created by, for example, providing a detour route creation mode in the application that creates the set route R1, or by the user tracing any road on a map with the mouse of the PC 30.

[0177] The created detour routes R2 and R3 can be registered with a name such as "detour route 1" and any user comments about the detour route. The detour routes R2 and R3 can be colored differently from the recommended route R1 on the map display screen so that they can be distinguished from the recommended route R1.

[0178] When the detour routes R2 and R3 are displayed on the map, the name of the detour route and the user's comments may also be displayed on the map, or the name and comments may be displayed when the user places the cursor over the detour route.

[0179] (F) The control unit 31 of the PC 30 may display the recommended route R1, which has been changed to pass through the detour routes R2 and R3, together with the original recommended route R1 on the display unit 33. This allows the user to visually recognize the change in route and easily determine whether the change was appropriate. The original recommended route may be colored, for example, in a lighter or different color, to make it easier for the user to recognize it as the original route.

[0180] (G) While the user is traveling, the control unit 18 of the navigation device 1 displays information about the set route R4 on the display unit 5 for route guidance, allowing the user to travel smoothly according to their pre-planned trip. However, users often change their travel route on the spot due to traffic congestion or an object that catches their eye, which is also part of the fun of traveling. In such cases, the control unit 18 displays the difference between the set route R4 and the traveled route R5, which is the route the user is traveling. The user can experience the thrill of deviating from their plans and taking an adventure. The control unit 18 also stores the route the user actually traveled in the memory unit 19 as information about the traveled route R5. This allows the user to prepare to enjoy their memories after the trip.

[0181] As a display mode for the difference between the set route R4 and the traveled route R5, for example, while the user is traveling along the set route R4, an icon may be displayed moving on the set route R4, similar to a typical navigation display, and when the user deviates from the set route R4, the path the user is traveling from the point where they deviated may be colored in a color different from the set route R4. When the user returns to the set route R4, for example, the display may be restored to one in which the icon moves along the set route R4, with the portion of the route that deviated from the set route R4 being highlighted.

[0182] The display of the planned route R4 and the recording of the traveled route R5 are performed by the control unit 18 of the portable navigation device 1, which is an electronic device different from the PC 30 that creates the planned route R4 before travel. Because different electronic devices can be used depending on the situation, a simple and highly flexible system can be provided.

[0183] It is advisable to create the set route R4 on the PC 30 at home, display the set route R4 on the portable navigation device 1, and record the traveled route R5.

[0184] Data exchange between the PC 30 and the navigation device 1 may be performed using a storage medium such as an SD card or a USB memory. Alternatively, so-called cloud computing may be used. In other words, data created by one electronic device may be transferred to another electronic device. The data may be transmitted to a server on the network, and the server may then transmit the transmitted data to the other electronic device.

[0185] (H) The control unit 18 of the navigation device 1 may display the detour routes R2 and R3 created by the user on the display unit 5 along with the set route R4 while the user is traveling. If a sudden traffic jam occurs at the local location, the user can refer to the detour routes R2 and R3 and flexibly change the travel route R5. For example, the detour routes R2 and R3 created by the user may not have been adopted as part of the set route R4 in the pre-planned route, but may become second or third candidates depending on the local conditions. Therefore, by displaying such detour routes R2 and R3 along with the set route R1 while traveling, the user can easily change the plan by referring to the detour routes R2 and R3, for example, when encountering traffic jams.

[0186] (I) The control unit 31 of the PC 30 may create points P2 to P6 at arbitrary positions on the travel route R5 and register information relating to the points P2 to P6.

[0187] By creating points P2 to P6 at any position on the travel route R5 and registering information related to those points P2 to P6, you can easily record various memories of your journey along the travel route R5, making it a highly convenient tool for enjoying your trip.

[0188] Points P2 to P6 may be created, for example, according to user input, or may be automatically set every predetermined distance, such as every 10 km, or every predetermined time, such as every hour, or may be automatically set according to a predetermined condition, such as when the user deviates from the set route.

[0189] When points P2 to P6 are created by user input, information related to the points P2 to P6 can be registered, for example, as photos of tourist spots taken by the user or food eaten by the user, or as comments from the user. Furthermore, when points are automatically set at predetermined distances, predetermined time intervals, or according to predetermined conditions, for example, video and audio recorded by a drive recorder installed in the vehicle can be extracted for each point and registered as information related to the points P2 to P6. For example, by registering conversations in the car when the user deviates from the set route R4, the user can clearly recall why they deviated from the set route R4 and enjoy the memories of their trip.

[0190] For example, if the system is equipped with a car navigation device operated by a touch panel, the user can touch a desired location on the displayed driving route to create points P2 to P6 at that location. Furthermore, once points P2 to P6 are created, a screen for registering information related to points P2 to P6 can be displayed. If the information is, for example, a user comment, a comment input screen can be displayed. If the information related to points P2 to P6 is, for example, an image or video, a screen for specifying the image or video to be uploaded can be displayed. If the information related to points P2 to P6 is, for example, video or audio recorded by a dashcam, a screen for specifying the extraction range of the video or audio can be displayed.

[0191] (J) The control unit 18 may create points P2 to P6 at positions on the travel route R5 that correspond to the position information included in the related information, and register the information as information related to the points P2 to P6.

[0192] For example, when an image is taken with a smartphone 60 equipped with a GPS function, the image is tagged with location information called a geotag. If the information to be registered includes such location information, the location on the travel route R5 corresponding to the location information is displayed. By creating points P2 to P6 and registering them as information related to the points P2 to P6, the user does not need to specify the points P2 to P6, and can easily register memories.

[0193] For example, when a user takes an image with smartphone 60, the geotagged image may be transmitted to navigation device 1, which is recording travel route R5. Navigation device 1 may read the location information contained in the received image, set points P2 to P6 at the corresponding positions on travel route R5, and further register the image data as information related to points P2 to P6.

[0194] (K) The control unit 18 may create points P2 to P6 at predetermined intervals along the travel route and register images or sounds captured at these points P2 to P6 as information related to the points. This allows the user to easily record memories without exerting any special effort. The predetermined intervals may be, for example, a predetermined time interval such as one hour, or a predetermined distance interval such as 10 km.

[0195] For example, the images or sounds can be obtained by connecting the navigation device 1 that records the driving route R5 to a drive recorder installed in the vehicle, and each time the vehicle reaches points P2 to P6, the images seen from the car window and the sounds inside the car that are continuously recorded by the drive recorder are extracted and stored as information related to points P2 to P6.

[0196] When extracting video, for example, it may be extracted as a still image or as a video of about 3 minutes. When extracting audio, it is recommended to extract about 1 to 2 minutes so that you can understand what kind of conversation was taking place in the car.

[0197] In this way, by utilizing dashcams, which are often installed in vehicles in recent years in preparation for traffic accidents and other troubles, users can enjoy their travel memories by listening to images from the car window and conversations inside the car captured by the dashcam, even on rushed trips where they don't have time to take photos.

[0198] (L) It is preferable that the creation of the set route R4 as advance preparation, the display of the set route R4 as route guidance during travel, the recording of the traveled route R5, and the display of the traveled route R5 and the set route R4 are all performed by the control unit 18 of the navigation device 1. This makes it easy to enjoy memories after a trip and to prepare for the trip before and during the trip all with a single electronic device, and it is possible to provide a navigation device 1 that is excellent in hospitality to the user.

[0199] For example, you can use portable navigation device 1 to create a set route in advance at home or on a commuter train, then take navigation device 1 into the car during your trip to display the set route and record the route you took, and after your trip you can take navigation device 1 home to display set route R4 and route R5 and enjoy your memories.Alternatively, you can bring portable navigation device 1 to a lodging facility during your trip and connect it to projector 80 or a TV to hold a screening, allowing you to enjoy your travel memories on a large screen.

[0200] If the portable navigation device 1 is a touch panel type, it is preferable to display a map on the touch panel and provide buttons for the user to perform various input operations. For example, it is preferable to display buttons that function as cursor movement, right buttons, and left buttons of a mouse.

[0201] In addition, for example, a projector 80 is connected to the portable navigation device 1. In this case, a map can be projected onto a screen or wall, and buttons for the user to perform various input operations can be displayed on the touch panel, allowing the user to enjoy memories of their trip on a large screen while easily operating the portable navigation device 1 as a remote control.

[0202] Furthermore, for example, when setting and editing a route using the navigation device 1, the route may be changed by the user dragging a part of the recommended route R1 with his / her finger on the touch panel. Alternatively, for example, the user may create detour routes R2 and R3 by tracing any road on the map with his / her finger.

[0203] [Other embodiments] (1) In the above embodiment, an example was described in which the PC 30 and the portable navigation device 1 were used as electronic devices that make up the system, but the present invention is not limited to this.

[0204] For example, the functions described in the above embodiments can be implemented by installing a dedicated application on a mobile terminal device. Fig. 16 shows the appearance of a mobile terminal device suitable as another electronic device constituting the system of the present invention, and Fig. 17 is a functional block diagram of the mobile terminal device.

[0205] Here, a camera-equipped smartphone 60 is shown as an example of a mobile terminal device. The smartphone 60 includes at least a control unit 61, a communication unit 62, a storage unit 63, a display unit 64, an audio output unit 65, an input unit 66, an imaging unit 67, and a sensor unit 68. The control unit 61 includes a CPU that includes a microprocessor and its peripheral circuits.

[0206] The storage unit 63 is composed of a ROM, a RAM, etc. An OS (Operating System) and various application programs are installed in the storage unit 63. The CPU of the control unit 61 executes the OS and each application program installed in the storage unit 63, thereby controlling the smartphone 60.

[0207] The input unit 66 includes an input device such as a physical button or a touch panel. The control unit 61 receives input from the user via the physical button or the touch panel and performs various controls.

[0208] The display unit 64 includes a display device such as a liquid crystal panel, an organic EL panel, etc. The display unit 64 displays various menus, data, etc.

[0209] The imaging unit 67 is equipped with a camera and takes a picture of a subject through a lens provided on one or both sides of the housing. The display unit 64 functions as an electronic finder when the camera is started up, and displays a through image on the monitor as well as a captured image.

[0210] The sensor unit 68 includes various sensors such as an acceleration sensor, a geomagnetic sensor, a GPS (Global Positioning System) receiver, etc. In particular, by acquiring location information using a GPS receiver when capturing an image with the camera, location information known as a geotag can be added to the image captured by the imaging unit 67.

[0211] The communication unit 62 includes an antenna and communicates with external devices in accordance with cellular phone wireless communication standards such as 2G, 3G, 4G, etc. In particular, it transmits image data captured by the imaging unit 67 to the navigation device 1.

[0212] The smartphone 60 also has an SD memory card slot 69, which allows insertion of an SD memory card that stores a route information file including data on a set route and detour routes. Includes a memory card reader / writer that reads and writes information from and to the card.

[0213] It is preferable to install in advance application programs for setting and editing routes, and application programs for realizing a navigation function, a set route reproduction function, and a traveled route recording function, as necessary, in the storage unit 63 of the smartphone 60. The storage unit 63 also stores information necessary for route editing, such as map information, facility information, and input history. The CPU of the control unit 61 executes the route editing application program and reads and writes information stored in the storage unit 63, thereby realizing the functions.

[0214] For example, a user can create a set route in advance on smartphone 60 at home or on a commuter train, and then bring smartphone 60 into the car during the trip to display set route R4 and record traveled route R5. After the trip is over, the user can take smartphone 60 home and display set route R4 and traveled route R5 to enjoy the memories. Alternatively, the user can bring smartphone 60 to a lodging facility during the trip and connect it to projector 80 or a TV to hold a screening, allowing the user to enjoy the memories of the trip on a large screen.

[0215] It is preferable to display a map on the touch panel of the smartphone 60 and to provide buttons for the user to perform various input operations. For example, it is preferable to display buttons that function as cursor movement, right buttons, and left buttons of a mouse.

[0216] Furthermore, for example, when the projector 80 is connected to the smartphone 60, a map can be projected onto a screen or wall, and buttons for the user to perform various input operations can be displayed on the touch panel, allowing the user to enjoy memories of their trip on a large screen while easily operating the smartphone 60 in hand as a remote control.

[0217] For example, when setting and editing a route on the smartphone 60, the route may be changed by the user dragging a part of the recommended route R1 with his / her finger on the touch panel. Alternatively, for example, the user may create detour routes R2 and R3 by tracing any road on the map with his / her finger.

[0218] (2) In the above embodiment, the navigation device 1 has a main body 2 that can be easily attached to and detached from the cradle 3. However, the functions of the system of the present invention can also be realized with a fixed in-vehicle navigation device. For example, before starting a trip, a set route R4 can be created before starting a trip, and route guidance can be started using the set route R4 while simultaneously recording a traveled route R5. Then, while taking a break, for example, at a parking area, the set route R4 and traveled route R5 can be displayed to quickly reminisce or consider what route to take next. Alternatively, the traveled route R5 can be recorded using the navigation device, and the route information file can be retrieved using the SD memory card 22 and loaded into a smartphone 60 or laptop PC 30. The traveled route R5 can then be reproduced by connecting a projector 80 to these devices.

[0219] (3) In the route setting and editing function, it is preferable to display not only information about detours such as the detour routes R2 and R3 but also information about avoidance points and avoidance routes. The control unit 31 of the PC 30 may cause the display unit 33 to display information about the avoidance points or avoidance routes created by the user along with information about the recommended route R1.

[0220] By displaying the avoidance points or avoidance routes created by the user on the display unit 33 together with the recommended route R1, the set route R4 can be created while more reliably reflecting the user's knowledge and experience.

[0221] The avoided points or routes may be set as points or roads that should be avoided based on the user's personal experience and knowledge, such as congestion, accidents, narrowness of roads, etc.

[0222] To create an avoidance point or route, for example, an avoidance route creation mode may be provided in a route setting and editing application. The system may create an avoidance route by accepting user input. For example, the control unit 31 may display a map on the display unit 33, and the user may input by clicking any point on the map with a mouse or tracing a road with a mouse or the like, and the system may accept the input and create an avoidance route. The created avoidance point or route may be registered with a name such as avoidance point 1 or avoidance route 2, either automatically or based on user input. Furthermore, information regarding the avoidance route may include not only the avoidance route itself but also related information such as user comments about the route.

[0223] The avoidance points or routes should be colored in a different color from the recommended route R1 and the detour route on the map on the display screen so that they can be distinguished from the recommended route R1 and the detour route. The avoidance points may also be displayed with an illustration such as a flag.

[0224] When an avoidance point or route is displayed on a map, the name of the avoidance point or route and a user comment may also be displayed on the map, or the name and comment may be displayed when the user places the cursor over the avoidance point or route. [Explanation of symbols]
