Abstract:
The present invention is directed to a method and apparatus for sending and retrieving location relevant information to a user by selecting and designating a point of interest that is displayed on a graphical user interface and sending the location information associated with that point of interest to a receiver that is also selected using the graphical user interface. The location relevant information may also include mapped routes, waypoints, geo-fenced areas, moving vehicles etc. Updated location relevant information may also be continuously sent to the user while generating updated mapping information on the graphical user interface. The present invention may be practiced by using communication devices such as a personal computer, a personal digital assistance, in-vehicle navigation systems, or a mobile telephone.

Description:
BACKGROUND 
     1. Field of Invention 
     This present invention relates to a computerized mapping and real-time communication software program, and more specifically, to integrating or coupling computerized mapping and real-time communication software for the purpose of transferring location-related information using a real-time communication system. 
     2. Description of the Related Art 
     Computerized mapping and real-time communication software are independently achieving widespread use today. Such mapping programs are commonly used to automate tasks of calculating routes, viewing location-specific geographical areas for their spatial content, such as addresses, roadways, rivers, etc., and for the purpose of being used with Global Positioning System (GPS) devices for various applications, such as a personal navigation application. Mapping software programs apply to a wide variety of uses, such as personal navigation, telematics, thematic mapping, resource planning, routing, fleet tracking, safety dispatching (i.e., Police, Fire, and Rescue organizations), and a wide variety of specialized Geographic Information System (GIS) applications, all of which are well known to people skilled in the art. 
     Real-time communication software applications are also being used today in various applications, like Instant Messaging (IM) applications such as American Online&#39;s (AOL) IM (AIM), Yahoo&#39;s IM, and Microsoft&#39;s IM, all of which are well known to people skilled in the art. None of these prior art IM software applications contain mapping capabilities. These applications provide presence information about other users on a user&#39;s roster or buddy list, such as online, busy, away, on the phone, offline, etc., and are primarily used for noncommercial applications, such as for conversing with friends or buddies that are online. 
     Prior art applications provide various features, such as displaying driving directions (i.e., routes), Points Of Interest (POI), waypoints (such as personalized, user-specific, points on a route or along a track), etc., but do not enable the transfer of such information to other users in real-time. A user will typically copy an image of a map from a standard mapping program, usually with a highlighted route, and e-mail the bitmap image and/or directions to another user or group of users for the purpose of meeting at a specific location or POI, such as a restaurant. Alternatively, with the adoption of IM programs, users can transfer these images and directions, typically by using an integrated file transfer program (FTP) connection, in real-time to other users based on their presence, and obtain real-time feedback from their buddies about the destination POI or location and specific route used to get to the destination. 
     Current applications that integrate both mapping and real-time messaging are well known in the art, such as the Automatic Vehicle Location (AVL) or Fleet Tracking industry, where vehicles that have position devices, such as GPS, report their position to a centralized computer for the mapping and display of the vehicles&#39; locations. Some of these prior art systems may incorporate real-time messaging for the transfer of logistical information, such as pickup and drop-off status messages. However, these existing applications do not provide a method for dynamically and graphically transferring location-relevant information coupled with a spatial map. Additionally, these applications typically provide only one-way transfer of position information, from the mobile vehicle to the dispatcher application, either on a web-based or desktop-based program. Usually, there is no need to transfer the dispatcher&#39;s location to the mobile vehicle since the dispatcher&#39;s location is always stationary. Mobile devices typically use location telemetry devices to transmit their location in a pre-defined manner or by request, where the dispatcher&#39;s location request is usually initiated by clicking on a Graphical User Interface (GUI) or by using a set of preferences to automatically request position updates. These preferences are based on various parameters, such as reporting location updates based on the distance traveled by the vehicle or by using various time intervals to trigger position updates either by a push or pull method relative to the telemetry device. 
     Another problem with existing AVL software solutions are that most applications are web-based applications that only allow for static image-based mapping, such as those provided by various online mapping companies like MapQuest. Also, the mapping and communication systems are disjointed from each other, as is the case with various companies, such as Televoke, Inc. These static image-based mapping applications do not enable real-time graphical manipulation of POIs on the map, nor do they provide a graphical connection between the map and vehicle roster listing. Some AVL software solutions provide the ability to display moving vehicles on dynamically viewable maps. However, these solutions do not enable the user to select a vehicle on the map, nor a stationary representation of a vehicle in a roster list, in real-time for the purpose of sending the vehicle&#39;s location to other users, and thus do not allow the creation of ad-hoc position transfers between various parties. Some dynamic mapping applications, such as Microsoft&#39;s MapPoint application, allow users to select Points Of Interest (POI) generally for the purpose of providing additional information about the POI or enabling the user to add the POI to a route planner as a route start, end, or stop point. This POI is selected by ‘right-clicking’ on the object after it has been selected and then choosing the specific route option. However, prior art fails to provide real-time communication capability with location-relevant information (i.e., POIs) for the purpose of graphically sending location-relevant information in established or ad-hoc networks to other users or location-enabled devices. 
     Another problem with prior art, such as in the case of AVL software solutions, is that vehicles or other mobile devices that a user wishes to map must first be selected from a list of available position-enabled vehicles. These vehicles, however, must already be configured for mapping on a dispatcher&#39;s mapping application and do not enable position requests in an ad-hoc environment. Prior art AVL mapping and tracking systems, such as At Road Inc., only allow users to select from a list of pre-configured location-updating vehicles, and then require the user to press a button in order to map the location of the selected vehicle(s). A much better solution, as people skilled in the art will appreciate, is to select a user, device, or group of users and devices in a roster list and graphically drag-and-drop the selection onto an active map. This method significantly simplifies the process of identifying a single or group of user(s)/device(s) and mapping their location appropriately. Additionally, prior art AVL systems do not allow for the case of users or devices to disallow their position from being mapped on the current mapping application. 
     There also exists a need for the consideration of permissions in such a case of privacy concerns, where a real-time location request be sent across the real-time communication connection to the user, vehicle, or device, whose location information is being requested. The user, vehicle, or device can select the resolution of position information they want to communicate (i.e., latitude and longitude, or city, or state, or etc.) to control the level of accuracy to which they can be mapped. Once approved, this ad-hoc transfer of position information occurs and the graphical mapping of the received position information is completed on the requestor&#39;s mapping application. Thus, allowing users to initiate position requests graphically and in real-time, and providing the capability of ad-hoc position requests to other users not pre-configured to allow their location information to be mapped, provides an extremely efficient method and system when compared to prior art systems. 
     Another drawback of prior art is that integrated mapping and communication programs, such as AVL applications, provide the ability for the receiving of position information for mapping purposes only. These prior art systems do not provide the capability of sending, or pushing, location-relevant information, such as POIs, to other mapping programs or textual devices, such as Personal Digital Assistants (PDA), pagers, cell phones, etc. For instance, prior art mapping systems, such as Microsoft&#39;s MapPoint, allow the user to select POIs, such as restaurants and gas stations, but does not allow the user to transfer these POIs to other users, and more specifically does not allow users to graphically drag-and-drop these selections (i.e., POIs) for various purposes, such as to dynamically add them to a route planner for inclusion in an undefined route or pre-calculated route. 
     The integration of a highly dynamic mapping application and a real-time communication system enables users to select POIs, such as houses, theaters, city names, roads, etc., or icon representations of other users on a mapping program for the purpose of graphically sending location-relevant graphical information, such as the selected POIs, to a specific user on a roster listing of available online users in real-time. As people skilled in the art will appreciate, graphical location-relevant information is not limited to only POIs, but also includes mapped routes, waypoints, geo-fenced areas, planes, etc. A valuable feature that prior art fails to provide is the transfer mechanism that allows the ability to drag-and-drop this location-relevant map information (i.e., routes, geo-fenced areas, etc.) to the current application&#39;s roster list for such transfers. 
     Prior art systems, such as AVL software, also fail to provide the capability of allowing the map application user (i.e., in the case of an AVL software solution the user is typically denoted as the dispatcher) to send the position information of one vehicle to another vehicle on the user&#39;s roster list for an ad-hoc location transfer. This method of transferring information is best performed by dragging the icon representation of one vehicle to the icon representation of another vehicle in the user&#39;s roster list. Before the completion of the transfer of one vehicle&#39;s location information to another vehicle, where the user or dispatcher acts as the location-transfer hub, each user sets the appropriate permissions to allow the transfer. Thus, each of the vehicles&#39; roster lists do not need to be included in the other vehicle&#39;s roster list, since the user or dispatcher has both vehicles on its roster list and acts as the hub for the transfer of the position information. This creates a dynamic environment for ad-hoc position transfers that are not available in prior art systems. 
     As an additional drawback of prior art systems, there is no way to provide real-time route planning of a system consisting of a real-time communication system integrated with a mapping and real-time communication program. In other words, it is not currently possible for a roster icon representation of a vehicle or user to be graphically selected into, or dragged-and-dropped onto, a route planner for the purpose of setting a user&#39;s current position as a route&#39;s destination points, where the term ‘destination’ refers to a point or location on a map that the user indicates as a start of a trip, end of a trip, or stop or waypoint along a trip. Origin also is used to refer to the start of a trip. This route planning operation also applies to POI locations. For instance, prior art systems, such as Microsoft&#39;s MapPoint allows users to graphically alter a pre-calculated route, such as graphically indicating the portion of the route to alter. 
     However, current art systems do not allow the capability of selecting real-time location-enabled or static POIs (such as vehicles, restaurants, people, gas stations, houses, etc.) for the purpose of graphically adding to, or updating, a route&#39;s destination points in an undefined or pre-calculated route. Additionally, this prior art system application only allows the alteration of a route to a new destination by dragging the selected portion of the route to that new location. A more useful method, which can incorporate the integrated real-time communication system, is by allowing the user to drag a graphical representation of a location-relevant object, such as POI (i.e., restaurant, gas station, house, user, etc.), to the pre-calculated route itself or to a route planner, thus graphically altering the pre-calculated route by creating a destination point based on the dragged POI&#39;s location information. If the POI has a static location, and its position information is already known, then the real-time communication system is not utilized. However, if the POI is dynamic (i.e., a moving vehicle), then the real-time communication system is utilized to obtain the position information of the selected dynamic POI in real-time, thus producing a dynamically moving route, where the destination point can change its position in real-time, thus causing the route to continually update it parameters based on the moving object. Another advantage for using the dynamic route calculation, is as the POI moves its location, the entire route need not be re-calculated in real-time, but only that portion of the route that needs to be re-calculated. 
     An additional problem with current map planning applications or integrated mapping and real-time communication software applications, such as AVL software solutions, is that they do not provide the capability of allowing users to graphically transfer routes to other users in real-time. Current prior art systems that are capable of generating routes allow users to send route representations, such as bitmap images or driving directions, to other users either by e-mail or FTP connection, where these routes representations only provide a static set of information, such as the starting and ending (i.e., destination) points of the predefined route. The route is usually generated based on the sender&#39;s origin and destination, or is based on generic major roadways that are easily identifiable in the immediate area. 
     A more useful implementation, when compared to prior art systems, would enable users to transfer or ‘share’ pre-defined routes, including all of the destination and turn points of the route and all of the metrics used to calculate the route, in real-time, so that they can be incorporated into the recipient user&#39;s routes or dynamically viewed on the recipient user&#39;s map. In the case of an in-vehicle navigational system, transferring a vehicle&#39;s actual route to another vehicle or graphical application allows the other user to view in real-time the exact location of that vehicle relative to the route that vehicle is traveling along. An additional benefit of this more useful application would be that the recipient of the route would be able to use in their route planner tool the sent destination points (i.e., stop points, end point, etc.), and use their own current location as the route&#39;s origin. For example, prior art systems, such as MapQuest or MapBlast, allow users to send image representations of static routes to other users. However, these routes are relative to the sender&#39;s location. There needs to be a method to create a route that can automatically include the received route&#39;s destination points while recalculating the route relative to the recipient&#39;s current position. 
     Thus, a need exits for a method and system that allows users to graphically send, request, and plan, in real-time, location-relevant information between users and devices. Until now, an adequate solution to those problems has eluded those skilled in the art. Providing a solution enabling users to graphically send, request, and plan, in real-time, location-relevant information between users and devices would prove especially useful for wireless devices that incorporate positioning technologies, such as Global Positioning Satellite (GPS) devices. This provides great benefits to wireless in-vehicle navigational systems (i.e., telematics) and fleet tracking systems, since they would be able to make more efficient use of position information by including a real-time communication infrastructure and application with a graphically enabled interface. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide a method and system for the receipt of location-relevant information, or user or group contact information, such as personal data information (i.e., vcard or personal profile information), from a list of users or group of users, where users can include inanimate objects (i.e., phones, vehicles, boats, database, device, etc.) or living things (i.e., people, pets, etc.), for the purpose of mapping the location information by graphically selecting and dragging the icon representation of the user, contact, or group of users and/or contacts to a map. 
     In accordance with the preferred embodiment of the present invention, the location-relevant information can be stored locally, typically with contact information, cached from a recently received location update, or location information can be automatically requested in real-time from a specified user or group of users where a user may include an online database storage system. Once the location-relevant information (e.g., latitude, longitude, altitude, heading, etc.) has been received, that location is mapped based on varying resolution and size. In one embodiment, a user can select another user, typically from a roster list, and drag-and-drop the user onto a map in order to automatically map this other user&#39;s current location. The mapped user can be in the form of a contact, where the location information (i.e., vcard), such as an address, is typically stored locally in the storage system of the computing device, or the user can be in the form of a roster list of users connected via a real-time communication system. In the case of a roster list, the location information can be in the form of vcard information, and may also include position information from various positioning devices, such as a GPS device. In both cases, the remote user to be mapped (e.g., person, phone, vehicle, etc.) could receive a message showing the request for their position information. 
     Upon accepting the request to send their position information, the requesting user&#39;s real-time communication program would receive the remote user&#39;s position information from the remote user and transfer the remote user&#39;s position information to the requesting user&#39;s mapping application to be displayed on a graphical map. The remote user can also be considered to be in the form of an online database storage system. In essence, all of the previous steps are performed using a simple selection and drag-and-drop operation. It should be noted that the mapping application and the real-time communication application do not have to be fully integrated (i.e., they can be separate applications), but do preferably include a conduit for transferring position information between the two applications. Integrating the two applications typically provides for a better user experience, but is not required by this object. 
     It is another object of the present invention to provide a method and system for receiving location-relevant information from a list of users or group of users, where users can include inanimate objects (i.e., phones, vehicles, boats, etc.) or living things (i.e., people, pets, etc.), for the purpose of requesting, in real-time and in an ad-hoc environment, the users&#39; position information for mapping their location(s) by pushing a button or selecting from a menu list in a real-time communication program, such as an instant message application. In one embodiment, a user engaged in an instant message conversation with a mobile wireless phone user desires to obtain the position of said wireless phone user. The requesting user can push a button on the instant message window, or select a menu bar option, to initiate the request of the wireless phone user&#39;s position information. After the mobile wireless phone user has allowed the transfer of its own position information, the requesting user&#39;s mapping application can automatically display the location of the wireless phone user. Additionally, the requesting user could have also initiated the position request by selecting the body of an instant message window and performing a drag-and-drop operation onto the mapping application. In this manner, the user is able to request the position information of another user and automatically map it quickly, easily, using an ad-hoc position request method and system. 
     It is another object of the present invention to provide a method and system for sending location-relevant information to a single or list of users or group of users, in real-time and ad-hoc environment, by pushing a button on a real-time communication instant message window. In one embodiment, a user engaged in an instant message session can push a button to send their own position information to the other user or group of users that are currently participating in the instant message session. The recipient user or group of users can have the option to accept or decline the transfer of the said position information, and, upon acceptance, the recipient user&#39;s mapping application can automatically perform a mapping operation. 
     It is another object of the present invention to provide a method and system for sending location-relevant information objects, such as routes, POIs, waypoints, user&#39;s locations, geo-fenced areas, vehicles, planes, etc., to other users or groups of users, where users can include inanimate objects (i.e., devices, phones, vehicles, boats, database, etc.) or living things (i.e., people, pets, etc.), by means of a graphical operation on a user or group in a list or on a graphical icon representation of a user or group and via a real-time communications system. 
     It is another object of the present invention to provide a method and system for selecting location-relevant information object(s) (e.g., routes, users, POI, etc.) on a graphical map for the purpose of sending location-relevant information object(s) to other users or a group of users by first selecting the location-relevant information object(s) and either using a graphical operation, such as dragging and dropping, the object(s) to a user or group listing representation, such as an icon of the destination user or group, or by selecting from a menu the user or group list of the destination user or group of users to send the location-relevant object(s) information to. In one embodiment, a user can select a position-enabled object (e.g. POI) from a graphical map and either drag-and-drop the POI to a user or group in a list, or select from a menu list the specific destination user or group of users to which the POI should be sent. 
     It is another object of the present invention to provide a method and system for allowing a user to accept or reject the receipt of location-relevant information, such as routes, another user&#39;s location information, POIs, etc., by their real-time communication program. Upon receipt of said location-relevant information, the information can be automatically mapped in an accompanying mapping application. The mapping application and the real-time communication application do not have to be fully integrated (i.e., they can be separate applications), but they do require a conduit, such as a software application program interface (API), for transferring said position information between the two applications. In one embodiment, a remote user that has been sent location-relevant information, such as a POI, can receive a notification message indicating that the POI will be transferred upon acceptance of the request. Upon acceptance of the request, the POI will be transferred to the destination user, who can then have the option to map the received POI or display the textual location and name of the POI, or both. This preference information can be configured in real-time or pre-configured in the application preferences of the real-time communication application. 
     It is another object of the present invention to provide a method and system for allowing a user to graphically initiate the transfer of location information, in an established or ad-hoc real-time environment, between a user or group of users, or any combination thereof. In one embodiment, a user that has a list of N other users can select an icon representation of a user or group of users and initiate the transfer of the location information of the selected user or group of users to a destination user or group of users other then themselves. The initiating user essentially acts as the hub for graphically initiating and transferring the location information between users and/or groups of users. The initiating user can perform this graphical initiation of a location transfer by highlighting a user or group of users from a list or graphical icon representation, and select from a pop-up menu or list the destination user or group of users to which the location information should be sent. Additionally, the initiator can start the location transfer by selecting the icon representation of the user or group of users from a list or graphical icon representation, and then dragging-and-dropping it to another icon or list representation of a user or group of users, or any combination thereof, for the purpose of sending or transferring said location information. Before the location transfer is completed, permission settings can be obtained from the origin and destination users or groups of users. It is not a requirement that the origin and destination user or group of users include each other in their own roster list, since only the initiating user needs to have both origin and destination users or groups of users in their roster lists. 
     It is another object of the present invention to provide a method and system for sending your position information to a list of users or group of users, in real-time, by selecting a graphical icon representation of yourself and dragging and dropping the icon onto a user or group of users. In one embodiment, a user wanting to send their own position information to a group of users can select their own icon representation and drag-and-drop said icon representation onto the icon representation of the group of users who should receive said position information. In one embodiment, each user in the group will have the option of accepting or declining said position information transfer, and each receiving user that accepts the position information transfer has a mapping application that automatically performs a mapping operation to display the received position information on a graphical map. 
     It is another object of the present invention to provide a method and system for receiving a route that may or may not include the sender&#39;s real-time location along that route for display in real-time on the recipient&#39;s graphical mapping application. In one embodiment, an in-vehicle navigation system on a defined route may need to transfer that route to a desktop computer. The route, and all of its parameters, can be transferred to the desktop&#39;s mapping application for display. Additionally, the sender of the route can include and send their own real-time position information with the route for display on the desktop computer&#39;s mapping application. When the sender initiates such a transfer, the sender&#39;s real-time communication application is configured to send its own location on the route to the recipient, via a real-time communication system, at any given interval of time, distance change, or upon the sender&#39;s request. The recipient&#39;s real-time communication application is configured to receive these location updates from the sender, which then triggers the recipient&#39;s mapping application to display the updated location of the sender. Thus, the real-time communication application not only provides the ability to send the route, but to transfer the vehicle&#39;s real-time position information in order for it to be mapped. 
     It is another object of the present invention to provide a method and system for sending routes to other users and enabling the recipients of said routes to dynamically change the received route&#39;s origin to be the recipient&#39;s current location or the closest starting position relative to the received route. The destinations in the received route can remain a common element between the sender and the recipient, but the origin, or closest starting position relative to the received route, can change to be the recipient&#39;s current position information on the received route, thus allowing a new route to be calculated based on the recipient&#39;s current position information and a common set of received destinations. All of the received destinations are optional, but at least one received destination is required to calculate a new route from the recipient&#39;s current position. For example, if the initiator sends, or shares, their current route with another user (i.e., recipient), the recipient user can receive the sent route with the original origin and destinations of the route. The recipient&#39;s mapping application can then dynamically re-calculate a new route based on all or a subset of the received route&#39;s destinations and with an origin being the recipient&#39;s current real-time position information. 
     It is another object of the present invention to provide a method and system for graphically selecting a user or group of users, where a user can include an inanimate object (i.e., phone, vehicle, boat, etc.) or living thing (i.e., person, pet, etc.), or a contact, all of which have position information associated with them, and graphically modifying a pre-calculated route to include the location of the selected user(s) for the purpose of preparing and calculating a new route. In one embodiment, a user can select an icon representation of another user, group of users, or contact from a list and drag-and-drop said icon representation onto a pre-calculated graphically-displayed route for the purpose of modifying said route by inserting into that route as destinations the location(s) of the selected user(s), such that the inserted destinations are placed after the destination point that immediately preceded the route segment where the icon was dropped, and before the destination point that immediately followed the route segment where the icon was dropped. In this manner, the user is able to add a new route destination simply by dragging an icon representation of the user, group of users, or contact onto a pre-calculated route. 
     The position information can be either locally stored, as is typically the case with contacts, or can be retrieved and updated in real-time as the position information changes, which may be very useful for a user that is defined as a mobile phone or vehicle. One advantage of the present invention is that the entire route need not be recomputed each time a destination is updated. Only the portion of the route that was changed can be recalculated. For example, if a route consists of origin point A and destination points B then C, and an additional destination is added in-between points A and B, then only the portion of the route between A and B needs to be recalculated to include the added destination. In another embodiment, a user can select another user, group of users, or contact icon representation from a list and drag-and-drop said icon representation into a route planner window, such that the order of the route destinations are arranged as previously described, with the new destination point being inserted in the route between the points immediately preceding and following the point where the icon was dropped. If there is no destination point immediately preceding or immediately following the point where the icon was dropped, then that new route destination point becomes the origin or destination, respectively, of the new route. The minimal route calculation can compute the route segment consisting of the new destination point and the destination points immediately preceding and immediately following the new destination point can then be recalculated. However, the entire route may be recalculated to maximize overall route optimization. The retrieval of the position information is the same as described in previous objects, but in this embodiment the route would not automatically calculate a new route until the user instructs it to be calculated. 
     It is another object of the present invention to provide a method and system for graphically adding location-relevant information objects, such as POIs, city names, street names, user icon representations, vehicles, etc., as additional destinations to a pre-calculated route or to a route planner. In a mapping application, graphically selecting location-relevant information objects, such as POIs, dragging said objects to a pre-calculated graphically-displayed route, and dropping said objects onto the route enables the addition of destination points, based on the selected location-relevant information objects, along said route at the point where they were graphically dropped. The need for the mapping program to calculate which portion of the route to alter is eliminated since the user selects the appropriate portion directly with the selected location-relevant information object. In one embodiment, a location-relevant object, such as a gas station POI, is selected and dragged to the graphically displayed pre-calculated route, and then dropped onto a particular route segment on the map. This action automatically adds the POI as a destination point, where the order of the destination point in the route is determined by the object&#39;s drop point, and automatically recalculates the route with the new inserted destination point included. Another benefit is that the entire route need not be recalculated, but only the segment of the route upon which the object was dropped needs to be computed. For example if 6 points define a route and a POI is added between points  5  and  6 , the drop point being labeled point  5   a , then only the route segments from point  5  to  5   a  and from point  5   a  to  6  need to calculated, not the entire route (i.e., points  1 ,  2 ,  3 ,  4 ,  5 ,  5   a , and  6 ). 
     This object also applies to another embodiment of a method for graphically selecting location-relevant information objects, such as POIs, and dragging-and-dropping said objects to a route planner for the purpose of adding additional origin or destination points along said route. The difference in this embodiment is that the POI is not dropped onto a pre-calculated graphically displayed route, but onto a route planner instead. The benefit of the previous embodiment also applies to this embodiment, in that the entire route does not need to be recalculated, but only the portion of the route into which the new destination point is inserted can be recomputed. Also the route can be a pre-calculated route or a route that is being planned and still needs to be calculated. 
     It is another object of the present invention to provide a method and system for selecting a graphical icon representation of a user on a map and dragging it onto a POI on a map, or visa versa, for the purpose of creating a dynamically-generated real-time route and adding that route between the location user and POI to a route planner. The selected user&#39;s position information is updated either through the real-time communications system, or if the selected user is the application user, the position information is updated from a locally connected positioning device (e.g. GPS). The POI is sometimes considered a static location-relevant object, such as a gas station, house, restaurant, city location identifier, etc., whose position remains relatively unchanged. In one embodiment, a user tracking a vehicle on a map that wishes to obtain a route for said vehicle to a gas station can select the vehicle&#39;s graphical icon representation on the map and drag-and-drop it onto an icon representation of a restaurant on the map. This action can generate a route from the selected vehicle&#39;s current position on the map to the location of the restaurant and may create a new route in a route planner consisting of the origin as the selected vehicle&#39;s current location and the destination as the selected POI&#39;s location. 
     One advantage of this method and system is that the real-time communication system allows the vehicle to move while the route is dynamically updated using the vehicle&#39;s new position information as the origin of the route and using the restaurant POI as the destination. Another benefit of this object is that if there are two or more destinations (i.e., three or more route points) the entire route does not need to be recalculated, but only the portion of the route that has been changed, by real-time position updates of location-relevant objects such as the vehicle, needs to be computed. 
     It is another object of the present invention to provide a method and system for graphically creating a dynamic route between two moving location-relevant objects on a map. A location-relevant object is a map object that has a spatial component associated with it, such as latitude and longitude values, and is graphically selectable by the user. Selecting an icon representation for a dynamic location-relevant object, such as a vehicle, person, plane, boat, etc., where the position of the dynamic location-relevant object can change with time and its real-time position updates can be received via the real-time communications system or locally when connected to a local positioning device such as a GPS receiver, and dragging and dropping said object representation onto another icon representation of a dynamic location-relevant object will create a route between the two dynamic objects and/or add the objects into a route planner, depending on the user&#39;s preferences. The object that was first selected is considered the starting point, or origin, of the route, and the second selected object is considered the destination point of the route. If any new position updates for either dynamic location-relevant object occurs, the route between the two dynamic location-relevant objects will be re-calculated, thus enabling a constantly updated dynamic route. Another benefit of this object is that if there are two or more destinations (i.e., three or more route points) the entire route does not have to be recalculated, but only the portion of the route that has changed, including any real-time position updates of location-relevant objects. 
     It is another object of the present invention to provide a method and system for graphically adding location-relevant objects on a map to a route planner. The selection of an icon representation of a location-relevant object on a map, such as a vehicle, pet, person, boat, wireless phone, computer, city name, street name, park, etc., followed by the use of a drag-and-drop operation to a route planner window in order to drop said location-relevant object into the route planner window adds the said object to the route planner for the purpose of either updating a pre-calculated route or creating a new route. The order that the location-relevant object is dropped into the route planner window directly affects the order of the destination points of the route, and thus the route itself. In one embodiment, a route planner window display consists of a route with three destination points (i.e., four route points including the origin). Selecting an icon representation of a location-relevant object, such as a wireless phone, and then dragging-and-dropping the icon into the route planner between the first and second destination points causes the wireless phone object to become the second destination in the route. Since the wireless phone&#39;s location can change with time, the route will be a dynamically calculated route based on changes in its position. Another benefit of this object is that if there are two or more destinations (i.e., three or more route points) the entire route does not have to be recalculated, but only the portion of the route that has changed, including any real-time position updates of location-relevant objects. 
     It is another object of the present invention to provide a method and system for creating a route by graphically dragging-and-dropping a list or icon representation of a user or group of users onto another list or icon representation of another user or group of users. A route can then be generated between the two location-relevant user objects, or the objects can be included in a route planner window for the purpose of planning a new route. In one embodiment, the origin route point is defined as the first selected and dragged location-relevant user object, and the destination route point is defined as the location-relevant user object that the first object was dropped upon. The position information for these location-relevant user objects, if not stored locally, can be retrieved in real-time using the real-time communication system. In another embodiment, the location retrieval process is based on the approval of the transfer of the required location information by the users. 
     It is another object of the present invention to provide a method and system for generating or planning a route from a user&#39;s current position information to or from the location of a location-relative object that is selected from a list or graphical icon representation on a map using a drag-and-drop action. In one embodiment, a user can select a graphical icon representation of themselves in a list and drag said representation to the graphical icon representation in a list or on a map of any location-relevant object on a map, such as another user or a static POI, for the purpose of generating a route. The route&#39;s origin can be the user&#39;s current position information, and the destination can be the position information of either a dynamic location-relevant object, such as a mobile user, where the real-time position information is received via the real-time communications system, or can be a static location-relevant object, such as a POI (i.e., gas station), where the position information may already be known. In the case where the position information for a POI is not known, it can be retrieved using the real-time communication system connected to a database where the appropriate position information is stored. 
     It is another object of the present invention to provide a method and system for generating a graphical route history based on a dynamically generated or changing route. A pre-calculated route with two or more destination points will be recalculated when any of those destination points change due to a position update via the real-time communication system. Instead of deleting the previous pre-calculated-route, the route portion that is different from the original route is graphically displayed differently than the recalculated route, thus providing the user with a greater amount of information. In one embodiment, an icon representation of a location-relevant object, such as a car, that has been included into a pre-calculated route along with a stationary POI, such as a gas station, can initially display the pre-calculated route on a map. If the car&#39;s position, as updated via the real-time communication system, changes and is updated on the map display, such that the previous pre-calculated route no longer applies, a new route can be calculated based on its new position information and displayed. The previous pre-calculated route can be displayed using a different highlighted color and pattern than the new route that was just calculated. Another benefit of this object is that if there are two or more destinations (i.e., three or more route points) the entire route does not have to be recalculated, but only the portion of the route that has changed will be displayed differently than the new route segment.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The details of the preferred embodiments of the present invention will now be described with references to  FIGS. 1-32 . 
     The present invention provides a method and system for graphically sending (and sharing), retrieving, and planning location-relevant information with a mapping and real-time communications applications, where both applications can be integrated into one application or each application is separate and capable of communicating with the other. The present invention may be embodied in a mapping and real-time communication application, such as the “Map Messenger” application owned and licensed by the Networks In Motion Corporation of Pasadena, Calif. 
       FIG. 1  illustrates a high-level diagram of one environment that is a suitable computing and networking environment in which the invention may be implemented. The invention will be described in the general context of an application that executes on an operating system in conjunction with a personal computer, but those skilled in the art will realize that this invention also may be implemented in combination with other program modules. Program modules typically include routines, programs, data structures, etc. that perform particular tasks or implement particular abstract data types. This invention is not limited to a typical personal computer, but may also be utilized with other computing systems, such as handheld devices, mobile laptop computers, wireless phones, in-vehicle navigation systems, programmable consumer electronics, mainframe computers, distributed computer systems, etc., and the like. 
       FIG. 1  includes a typical personal computer  100 , that includes a central processing unit (CPU)  135 , video adapter  134 , hard disk drive  107 , optical disk  108 , serial port  109 , magnetic disk drive  110 , system bus  106 , and network interface  136 . The hard disk drive  107  typically refers to a local non-volatile storage system for storing large amounts of data, such as map data. The optical disk  108  typically refers to a CD-ROM disk used for storing read-only data, such as an installation program. The serial port interface  109  is typically used to connect  113  the computer  100  to external devices  111 , such as a keyboard, mouse, and graphical touch screen interface, and also can connect  137  to positioning devices  138 , such as a GPS receiver. The keyboard and mouse  111 , amongst other input devices  138 , enable users to input information into the computer  100 . The connection  113  &amp;  137  cables can include a serial cable or universal serial bus (USB) cable. Other input devices, that are not shown, may include a joystick, scanner, camera, microphone, or the like. 
     The magnetic disk drive  110  is typically used to store small amounts data, in comparison to a hard  107  or optical  108  disk drive, and typically lacks the data transfer rates of those other storage drives, but it enables both readable and writable capability. The hard disk drive  107 , optical disk drive  108 , serial port interface  109 , and magnetic disk drive  110  are all connected to the main system bus  106  of the computer  100  for transferring data. A monitor  116  or other type of display device, such as a LCD display, is connected  117  to the computer system&#39;s  100  video adapter  134 , which is connected to the system bus  106 . Additional peripheral output devices, which are not included in this embodiment, such as a printer, speaker, etc., can also be connected to a personal computer  100 . The system bus  106  also connects to the network interface  136 , central processing unit (CPU)  135 , and system memory  101 . The system memory  101  contains both random access memory (RAM)  103 , and read only memory (ROM)  102 , that typically consists of the BIOS (Basic Input/Output System) of the computer, necessary for containing basic routines that enable the transfer of information between elements within the personal computer  100 . The RAM  103  stores a number of program modules, such as the Mapping and Communication Program, including Map Data,  105 , and the Operating System  104  of the personal computing device  100  or personal computer  100 . One example of such a program module  105  can be the “Map Messenger” program previously mentioned. 
     A network interface  136 , shown in  FIG. 1 , illustrates how data is typically transferred between other computing devices  122 ,  126 ,  127 , &amp;  130  and a computer  100  through an Internet, Intranet, or Extranet network  124 . Additionally, this connection  115  can be implemented using a MODEM  112  that is connected  114  to the personal computing device  100  by using a serial port interface  109 . In one embodiment, a computer  100  can connect  121  to a network  124 , such as an Internet, Intranet, or Extranet, by various means that are well known in the art, such as by using a Digital Subscriber Line (DSL) cable. Additionally, a computing device  100  can also connect to the Internet  124  by means of a wireless connection  120  to a wireless base station  122 , where the antenna is coupled  119  to the network interface  136  of the computing device or personal computer  100 . The wireless base station  122  is also connected  123  to the Internet, Intranet, or Extranet network  124  by some means well known to people skilled in the art, such as a T1 connection. A wireless base station  122  can represent a local area network (LAN) base station, such as that used in an office building, or a wide area network (WAN) base station, such as that used in a cellular, Personal Communications System (PCS), 3G, or the like, wireless phone network. The Internet, Intranet, or Extranet  124  allows for connection  129  &amp;  128  to other personal computing devices  126  &amp;  127 , such as a wireless phone, hand-held device, in-vehicle navigation (i.e., telematics device), or the like. The Internet, Intranet, or Extranet  124  is also connected  125  to a central or distributed server system  130 , however this connection is not necessary in a peer-to-peer environment. This server system  130  can contain a real-time communication server  132 , a mapping server  133  which can provide map data for devices that do not have large storage capabilities, and a database  131  where location-relevant information such as POIs can be stored. 
     The real-time communication system  150 , as illustrated in  FIG. 1A , can be either one of two possible systems, both of which apply to this invention. The first embodiment is a peer-to-peer system, where each computing device  100 ,  126 , &amp;  127  is connected to the Internet, Intranet, or Extranet  124  by some means  120 ,  122 , &amp;  123 , or  121 , or  115 ,  112 , &amp;  114 , or  129  or  128 , such as a wireless connection or landline connection. This connection provides the capability for all computing devices  100 ,  126 , &amp;  127  to communicate directly with each other, in a peer-to-peer manner. This peer-to-peer environment allows for an ad-hoc user-to-user configuration for sending data to and from all users. The second embodiment, sometime referred to as a star configuration system to people skilled in the art, uses a centralized (or distributed) server system  130  that is connected  125  to the Internet, Intranet, or Extranet  124  providing the infrastructure for all computing devices ( 100 ,  126 , &amp;  127 ) where each user&#39;s computing device  100 ,  126 , &amp;  127  is connected directly to the server system  130 . The server system effectively acts as a router for passing location data to and from individual or groups of users. 
       FIG. 2  illustrates an application screen display of the Real-Time Communication and Mapping Program (RTCMP)  201  with a sample map  224  displayed below a menu bar  200 . A location-relevant object is a map object that has a spatial component associated with it, such as latitude and longitude values, and is graphically selectable by the user. Identified on the map display  224  are several location-relevant objects  211 ,  210 ,  212 ,  206 ,  205 ,  203 , &amp;  204 , that are selectable either in the RTCMP  201 , or, when the two applications have been separated, such as shown in  FIG. 4A , in the mapping application  419 . A user is an entity, which can be an inanimate object (i.e., phone, vehicle, boat, etc.) or a living thing (i.e., person, pet, etc.) that uses the real-time communications system to communicate with other users. An example of various location-relevant objects, as shown in the sample map  224 , includes a person (i.e., user)  211 , vehicle (i.e., user)  205 , plane (i.e., user)  203 , POI (i.e., a gas station)  210 , map identifier (i.e., city name)  212 , route  206 , and a geo-fenced boundary  204 . A route  206  is comprised of an origin  207  and one or more destination points  209  &amp;  202 , which can each be considered a “link”. the route is illustrated as a series of links, such as link  209  that connects an origin  207  and a destination  202 . It should be noted, and appreciated to those skilled in the art, that a link need not be a straight line as illustrated in the sample map  224 , but rather follows the topography of the roadways calculated between two route points, such as an origin  207  and destination  202  point. However, for simplicity, all links are illustrated as straight lines. 
     Also provided in the RTCMP  201  is an icon pointer  208 , or cursor, that provides a signal to the RTCMP  201  to indicate an active segment of the display  201 . When an element or object of the screen display is coincident with the focus of the icon pointer  208 , that element or object is said to have the focus of the icon pointer  208 . When the input device, such as a mouse, receives a triggered input, such as a mouse click or tap of a touchpad, the element having the focus of the icon pointer  208  at that moment is selected. 
     The real-time communication  212  part of the application is illustrated to the left of the map  224 . The real-time communication feature  212 , denoted as the messenger window, preferably provides a listing of users that are connected, in real-time communication, to the user&#39;s application. This list of users  212  is denoted as a roster list of users. The top-level user  213 , or the controller of the RTCMP  201  program, is illustrated as “User A”  213 . “User A”  213  has two groups  214  &amp;  219  beneath it, with each group consisting of four users. The first group, denoted as “Group 1”  214 , has four users organized within it, “User 1”  215 , “User 2”  216 , “User 3”  217 , and “User 4”  218 . The second group, denoted as “Group 2”  219 , also has four users beneath it  220 ,  221 ,  222 , &amp;  223 , where a user in this group  219  is represented here as, for instance, a vehicle. 
       FIG. 3  illustrates one embodiment of a situation where a user can map another user&#39;s location using a simple graphical method of selecting a user, contact, or group of users or contacts, and dragging-and-dropping its graphical representation onto the map display  224 . For example, in order to map “User 1”  215  icon pointer  301  is used to select the roster list representation of “User 1”  215 , typically by such mechanisms as a mouse “click-hold” or a “tap-hold” of a touchpad for a handheld device. This action typically provides feedback to the user by highlighting or outlining  306  the selected user, such as “User 1”  215 . The list representation of “User 1”  215  is then dragged  302  into the map display  224 , and “dropped”  303 , such as when the mouse “click” (or button) or the tapped-hold in a handheld device is dropped. People skilled in the art know that a “drag” or “drop” operation for a desktop computer with a mouse is different than a handheld device, but the essence of both operations remains the same. The drop action generally occurs when the user stops dragging the icon pointer and releases the mouse button. The release of the mouse button, at the point of the focus of the pointer  301  and at the moment the mouse button is released anywhere on the map display  224 , is identified by the RTCMP  201 . 
     This “drag-and-drop” operation signals to the RTCMP  201  program to initiate a location request, depending on whether the location information for the selected roster list user is stored locally, as in the form of a contact  311 , or remotely, as in the form of a user  215  connected by the real-time communication system  150 . If the selected user&#39;s location information is stored locally, as is the case with a contact whose location information is typically stored in a vcard that is located locally in the storage medium (such as a hard disk drive  107  or magnetic disk drive  110 ) of the computing device  100 , then the location request retrieves the said location information and uses that for the mapping operation. If the location information is stored remotely, or is updated in an on-demand format, then the real-time communication system  150  is used to retrieve the location information from the remote user, such as “User 1”  215 . 
     In one embodiment, “User 1”  215  represents a user with a wireless phone. After the process of “dragging-and-dropping” the user&#39;s graphical representation, such as “User 1”  215 , onto the map display  224 , the RTCMP  201  uses the real-time communication system  150  to initiate a request for “User 1&#39;s”  215  location. This location request is communicated via the real-time communication system  150  to “User 1&#39;s”  215  computing device application and either notifies “User 1” of the location request or automatically retrieves “User 1&#39;s” current location information from “User 1&#39;s” RTCMP  126 . A notification of a location request is given to “User 1” if its permissions and/or preferences that specify notifications of location requests are preferably required for “User A” or for all users on “User 1&#39;s” roster list. Note that “User 1&#39;s” RTCMP  126  does not have to be in the exact form of “User A&#39;s” RTCMP  201 , but only provide the functionality required by the real-time communication system  150  for the sending of location-relevant information. For instance, “User 1”  215  does not have to have a positioning device, such as a GPS device  138 , connected to their RTCMP  126 . The location information for “User 1”  215  may only include its vcard information, which is stored locally on “User 1&#39;s” computing device. After the location information from “User 1”  215  has been retrieved and sent back through the real-time communication system  150 , “User A&#39;s” RTCMP  201  maps “User 1&#39;s”  215  retrieved location on the map display  224  of varying resolution and size.  FIG. 5  illustrates “User 1&#39;s” current position  501  on a map display  224  of “User A&#39;s” RTCMP  201 . 
     Additionally, in another embodiment shown in  FIG. 3 , “User A”  213  can select  304  a contact, such as “Contact 1”  311 , and, using the same “drag  305  and drop  303 ” method, can map the contact&#39;s location information on the map display  224  of varying resolution and size. As people skilled in the art will appreciate, this “drag-and-drop” method allows users to retrieve and map location information locally or remotely through a real-time communication system  150 . In another embodiment, illustrated in  FIG. 4 , a typical Instant Message (IM) window  407 , known to people skilled in the art, includes, for desktop computing devices, a menu bar  410 , text entry window  405 , and a send button  406  for use in transferring composed messages. An IM window  407  typically also displays the user identification token  409  (i.e. user&#39;s name, email address, etc.) of the remote user to which these instant messages are being sent. While engaged in an instant message session with another user  409 , the local user (i.e., “User A”  213 ) preferably types messages that are viewable in the message window display  408 , also included in a typical IM window  407 . As people skilled in the art will appreciate, in one embodiment, a method for mapping  401  and requesting a user&#39;s text location  403  information, as shown in  FIG. 4 , can be implemented by pressing a button  402  &amp;  403  on an IM window application. For example, if a user wishes to receive another user&#39;s current geo-coded street address information, without mapping that user&#39;s location on a map, such as receiving the text “738 Lawrence Road, Pasadena, Calif., 91101”, a user only need to press a button  403  on an IM window  407 . The real-time communication system  150  preferably request from the other user their current location information, which includes obtaining their permission for transferring the said location information. 
     One embodiment of such a permission request is illustrated in  FIG. 4B . For example, a user using a similar IM window  452 , which illustrates that real-time communication (i.e. instant messaging) is occurring with “User A”  450 . The other similarities to the previous IM window  407 , such as the menu bar  460 , send button  453 , and message composition window  454  are also shown. The location request  459  may resemble a message in the message window display  451 , displaying the option to accept  455  or decline  458  the location request  459 . A user can accept  455  or decline  458  the location request  459  by using an icon pointer  457  to select either choice. Upon accepting the location request  459  from “User A”  450 , the local RTCMP would acquire its current position information from a positioning device  138  or from pre-defined position information, such as a default home address stored locally in a computer file. After the location information for the accepting user has been sent to the requesting user&#39;s (i.e. “User A”) real-time communication program, the IM window  407  will display said location information. 
     In another embodiment, “User A”  213  can request “User 1&#39;s”  409  location information for mapping. The same process is initiated and once the location information for “User 1”  409  has been obtained, a mapping program  413  or map display  224  preferably display on a map of varying resolution and size “User 1&#39;s”  409  current location  501 . Additionally, another embodiment for mapping “User 1&#39;s”  409  location information using the real-time communication system  150  is to graphically select  404  the message display window  408  of the IM window  407  and “drag  411  and drop  412 ” onto a mapping program  413 . This would cause the mapping program  413  to map the user&#39;s current location of varying resolution in the map display of the mapping program  413 . For both embodiments, where the real-time communication program  407  is not part of the mapping program  413 , a hardware or software conduit (e.g., API) is necessary in order to pass the necessary commands that will trigger the mapping program  413  to map the desired location of varying resolution. This mapping operation can also be completed using the ‘Locate On Map’  402  button or from a similar action familiar to those skilled in the art. 
     An additional benefit of this invention, as illustrated in  FIG. 4A , is that both the real-time communication program  414  and mapping program  419  need not be integrated into one application. The only requirement is that the two applications allow the transfer of the necessary data required for this invention, which can be accomplished, as people skilled in the art know, by using software API, DLLs, or the like. In another embodiment, as shown in  FIG. 4A , a location request and mapping event can be triggered using a real-time communication program  414 , by selecting from a menu  417  the function  418  to map a user&#39;s location. Current prior art system, such as Microsoft&#39;s MapPoint can be integrated with a PIM manger, such as Microsoft&#39;s Outlook to allow a user to initiate the MapPoint application such that it displays the address information of a contact by clicking a button in the PIM manager. However, the advantage of this invention over this and other prior art systems, as people skilled in the art will appreciate, is that the location-relevant data is obtained, in a graphical manner, via a real-time communication system  150  from other users or from an Internet-connected database  131 . 
     In another embodiment, a user can use an icon pointer  416  to select a user  421 , or set of users  415 , whose location information should be mapped on a separate, non-integrated mapping program  419 . The user can then invoke the appearance of a pop-up menu  417  or a menu available from the menu bar of the application  422 , and then choose the option from either menu to map the user&#39;s location. The appearance of the pop-up menu  417  can be invoked either by “right-clicking” the selected user&#39;s graphical representation in the roster list, or by using a tap-and-hold operation on a handheld device, which are all well known techniques to people skilled in the art. The pop-up menu  417  would illustrate various actions, one of which is mapping the selected user&#39;s location  418 . Selecting the option to map the selected user&#39;s location would cause the location information to be retrieved as previously described in this section. Once the real-time communication program  414  has received the location information from the appropriate user  421 , the program  414  would establish a connection with the mapping program  419  and pass the necessary data to initiate the mapping of varying resolution and size of the retrieved location information  420 . 
     This invention provides the ability send location-relevant objects to other users, and as people skilled in the art will appreciate, location-relevant objects may include routes. In one embodiment, as shown in  FIG. 6 , a pre-calculated route  206  is defined as having an origin  207  and one or more destinations  209  &amp;  202 . Making a route selectable by an icon pointer  604  enables the local user  213  to initiate the process of sending the route to a user, or group of users in their roster list, as shown in  FIG. 6 . To send a route to a user or group of users, a local user  213  first selects the route  206  with their icon pointer  604  and drags  602  the route to the graphical representation for the specific roster list user, such as “User 1”  215 , to which the route should be sent. The graphical representation for “User 1”  215  illustrates some feedback to the local user  213  controlling the pointer that the route selected  601  is ready to be sent. The feedback, as know to people skilled in the art, is typically shown as a highlighted image  603  on the graphical representation of the selected user that the dragged object should be sent to. 
     The two displayed icon pointers  604  &amp;  601  in  FIG. 6  illustrate different actions. Specifically, the first pointer  604  illustrates that a user is about to select a location-relevant object, while a second pointer  601  illustrates that an object has been selected and is now being dragged with the pointer  604 . Once the route  206  has been dropped onto the graphical representation of the destination user “User 1”  215 , the route is sent via the real-time communication system  150  to the destination user “User 1”  215 . In this embodiment, the destination user “User 1”  215  has an option to accept  1203  or decline  1204  the receipt of the route from the sender “User A”  213 . In one embodiment, as shown in  FIG. 12 , “User 1”  215  can receive in its IM window  1205  the request for the receipt of location-relevant information, indicating the option to accept or decline the receiving of said route by a message text question  1211  within the IM window&#39;s text display  1208 . The IM window  1205  is similar to the previously mentioned IM windows  407  &amp;  452 , since it also includes a menu bar  1210 , a user identification display of the current user the message window is connected with  1209 , a text entry window  1207  and a send button  1206 . The remote user, “User 1”  215  can accept  1203  or decline  1204  the transfer using their icon pointer  1202 . 
     Additionally, in another embodiment, a user can send a route  206 , shown in  FIG. 6A , using a similar approach. For example, a user  213  can select the route  608  and then immediately select the user “User 1”  215  to which the route  206  should be sent. This process does not require the drag-and-drop method, displays a different line type  607  to indicate the route sending selection process has begun, and consists of two back-to-back selection processes. The first selection  608  is the selection of the route  206  or location-relevant object, and the second selection  605  is the selection of the destination user  215  to which the route  206  should be sent. Prior to the second selection  605 , the local user  213  can move the pointer  608  over the destined user  215 , where the user  215  can highlight  606  indicating that the user  215  has been selected. Once the second selection  605  has been made, a menu  609  would pop-up displaying the options for the local user  213  to take, one of which, as in this case, is to send the route to the highlighted  606  user “User 1”  215 . Once the local user  213  moves the icon pointer  608  over the menu  609  and selects “Send ‘Route’ To User 1”  610 , as shown in  FIG. 6A , the route  206  will be sent to the user “User 1”  215  using the real-time communication system  150 . 
     Other embodiments exist for this invention for sending location-relevant objects, such as selecting a location-relevant object, such as a route  206 , as shown in  FIG. 7 . After the route  206  has been selected using the icon pointer  700 , a pop-up menu appears  701  that displays the local user&#39;s  702  roster list of users and groups of users, including the local user  702  itself. Using the icon pointer  802 , as illustrated in  FIG. 8 , the local user  213  can select  801  the graphical representation of the user  704  to which the route  206  should be sent. The process is completed when the user “clicks” or “taps” the destination user or group of users, or by an equivalent mechanism known to people skilled in the art. In this embodiment, the route  206  that is sent includes all necessary information to completely re-create the route  206  on the remote user&#39;s  704  application without any loss of information. 
     Other location-relevant objects, as people skilled in the art will appreciate, include POIs, such as map identifiers which include names associated specifically with a map, such as city names, street names, highways names, interstates names, rivers names, state names, or a map name that is associated with a location. A POI can include, without limitation, a house, business, person, pet, map identifier, etc., and is also a well known term to people skilled in the art. For example, if a map displays a name on a map display, then that location on the map can be assumed to be the location associated with the displayed name. This invention allows users to send map identifiers using the real-time communication system  150  to other users in their roster list or, in an ad-hoc manner, to other users identified by a unique identifier, such as an e-mail address, telephone number, or the like. 
     On a map display  224  a user  213  preferably uses the icon pointer  901  to select  903  a map identifier, such as a city name  902 . After selecting  903  the city name  902 , the user can drag  904  the location-relevant object to the graphical representation for another user  220  in the local user&#39;s  213  roster list. As an aid to the user  213 , the application can highlight  906  the specific user  220  that the icon pointer  905  is focused  220  on. Once the user  213  releases, or drops, the location-relevant object  902  on the destination user  220 , then the location-transfer process begins by using the real-time communication system  150 , sending the POI to the selected user as previously described, thus allowing the receiving user  220  to utilize the location-relevant object for a number of purposes, such as mapping, routing, etc. 
     Another embodiment of sending POIs, which include map identifiers, is illustrated in  FIG. 10 . After a user selects a map identifier, such as the city name Pasadena  902 , with an icon pointer  1001 , a new pop-up menu would appear  1002  showing the main user&#39;s  213  roster list. Selecting a user “Vehicle 1”  309  from this pop-up menu will initiate the sending of the selected POI  902  to the selected user  309 . Using the icon pointer  1101 , shown in FIG.  11 , to select  1103  the specific user  309  to send the POI to allow the local user to effectively send POIs over the real-time communication system  150  to any user in their roster list. 
     As people skilled in the art will appreciate, a local user of the RTCMP  201  program can transfer location-relevant information between users on their roster list, where the initiator acts as the location transfer hub of said location information. In one embodiment, as shown in  FIG. 13 , the local user  213  of the RTCMP  201  program can send the location information of “User 1”  215  to “User 4”  218  by using a graphical method. For example, the local user “User A”  213  can use the icon pointer  1316  to select  1302  the source user “User 1”  215 , where a selection is known to be made when the icon pointer  1301  is illustrative of a selected object, when compared to the normal icon pointer symbol  1316 . The graphical representation of “User 1”  215  can then be dragged  1304  to its destination position, which in this example is the graphical representation for “User 4”  218 , so that the location information of “User 1”  215  is transferred to “User 4”  218 . This action is competed in the RTCMP  201  program by moving the icon pointer  1301  to the new location  1303  over the destination user “User 4”  218 . The destination user “User 4”  218  is highlighted  1317  when the icon pointer  1303  is focused on the destination user “User 4”  218 . 
     The real-time communication system  150  provides the infrastructure for this transfer. The transfer occurs by requesting the location information from “User 1”  215  and after “User 1”  215  has agreed to sending their location information to “User 4”  218 , the location transfer can occur using a number of methods of the real-time communication system  150 . For example, a peer-to-peer method can be employed, sending the information directly from “User 1”  215  to “User 4”  218 , or the location-information can be sent to a real-time communication server  132  and then redirected to the “User 4”  218 . Additionally, the location-information can be sent from “User 1”  215  to the RTCMP  201  of the initiating user “User A”  213  and then sent to “User 4”  218 . The first two methods allow “User A”  213  to initiate the transfer, even if “User 1”  215  and “User 4”  218  do not have each other in their own roster lists, and the location-information does not necessarily ever have to be sent to the initiating user “User A”  213 . As people skilled in the art will appreciate, the mapping program does not need to be integrated with the real-time communication program in order to compete this transaction, as shown in  FIG. 4A  as “Application 1”  414 . 
     Another embodiment of transferring location information between other users, where the initiator acts as the location-transfer hub, is shown in  FIG. 13 . If the destination user is illustrated as an icon map object  1312 , representing “Vehicle 1”  220 , location-relevant information and objects can be transferred to the vehicle icon  1312 , and thus the user of “Vehicle 1”  220  by selecting objects and dragging and dropping them onto the icon representation of “Vehicle 1”  1312  on a map display  224 . For example, by selecting  1315  “Vehicle 4”  223 , using the icon pointer  1314 , “User A” can drag  1313  the icon list representation of “Vehicle 4”  223  onto the map icon representation of “Vehicle 1”  1312 , and drop or select the icon map representation of “Vehicle 1”  1312  using the icon pointer  1311 . This will initiate, as previously described, the transfer process of sending “Vehicle 4&#39;s”  223  location information to “Vehicle 1”  220  using a graphical method. Also, this process can be reversed, since the local user  213  can select  1311 , drag  1313  and drop  1314  the vehicle icon representation of “Vehicle 1”  1312  to the “Vehicle 4” user list representation  223 , thus initiating the location transfer from user “Vehicle 1”  220  to user “Vehicle 4”  223 . Additionally, this process can be done using a user&#39;s icon map representation  1308  to graphically initiate the transfer of “User 2&#39;s”  1308  current location information to another user&#39;s icon map representation, such as “Vehicle 1”  1312 . In another embodiment, selecting “User 2&#39;s”  216  icon map representation  1308 , and using the icon pointer  1309  to drag  1310  and using the icon pointer  1309  to drop the icon onto the “Vehicle 1”  220  user map icon representation  1312  initiates the location-transfer from “User 2”  216  to “Vehicle 1”  220 . 
     In another embodiment, a local user  213  can select  1306  a POI  1305 , such as a gas station, drag  1307  it to the vehicle icon map representation  1312 , and drop it, using the icon pointer  1311 , onto the vehicle icon map representation  1312  of “Vehicle 1”  220  in order to initiate the transfer of the POI  1305  to “Vehicle 1”  220 . The difference of this scenario compared to the previous location-transfers, is that the location for the POI  1305  is known, or not changing since the POI  1305  is a static object (i.e., similar to a map identifier), prior to the start of the location transfer process. Thus, a location request need not be sent to the POI  1305 , since its location is already known. The real-time communication program of the RTCMP  201  will then transfer the location-information of the POI  1305  to the selected user  1312  immediately upon their acceptance of the transfer. 
     Another advantage of this invention is that it allows a local user  213  to send their current location to another user on their roster list graphically. In one embodiment, shown in  FIG. 14 , “User A”  213  uses the icon pointer  1402  to select  1401  their own icon list representation and then drags  1403  the icon pointer  1405  to another user&#39;s icon list representation  218 . The highlight  1404  is shown to illustrate that the icon pointer  1405  is over “User 4&#39;s”  218  icon list representation. Dropping or releasing the icon pointer  1405  initiates the transfer of the location information of “User A”  213  to the selected user “User 4”  218 , and sends the location information after the requested user “User 4”  218  has accepted the transfer of said location information. As people skilled in the art will appreciate, this graphical transfer of the local user&#39;s location information significantly reduces the process required in prior art systems. 
     As illustrated in  FIG. 6 , the invention allows a user to send a route to another user. After the destination user has accepted the route, as illustrated in  FIG. 12 , if the remote destination user is running a RTCMP  126  similar to the sender&#39;s RTCMP the received route  1505  will be displayed in the destination user&#39;s map display  224 , as shown in  FIG. 15 . The received route  1505  is the same as the original route  206 , with the same origin  1501  and destination points  1502  and  1503  as the original route  206 , except that the received route  1505  is being displayed on the destination user&#39;s (“User 1”)  215  RTCMP  126 . Additionally, the sender  213  has the option to also send their own real-time location information  1504  via the real-time communication system  150  to the destination user  215 , which can then be graphically displayed on the map display  224  of the destination user&#39;s (“User 1”)  215  RTCMP  126 . As people skilled in the art will appreciate, this allows users to send or share routes with other users in real-time. 
     An additional benefit of this invention, as shown in  FIG. 16 , is that the received route  206  does not have to include only the sending user&#39;s (“User A”)  213  original route origin and destination points, amongst all the other parameters that completely define the sent route, such as the map database identifier, all relevant turn points, user preferences, etc. The destination user&#39;s (“User 1”)  215  RTCMP  126  can automatically adjust the received route&#39;s  206  origin and destination points based on the destination user&#39;s (“User 1”)  215  RTCMP  126  preferences. For example, the new origin of the received route can be automatically changed to the destination user&#39;s (“User 1”)  215  current location information or to a chosen origin location, and the sent route  206  can then be recalculated and displayed on the destination user&#39;s map display  224 . 
     In one embodiment, illustrated in  FIG. 16 , the original received route  1505 , consisting of origin  1501  and destination points  1502  &amp;  1503 , is displayed on the local user&#39;s (“User 1”)  215  map display  224 . Additionally, the real-time location information  1504  of the sending user (“User A”)  213  is also sent to the local user&#39;s (“User 1”) real-time communication program and displayed on the map display  224  of the local user&#39;s (“User 1”)  215  RTCMP  126 . A received route may include a destination location where the local user (“User 1”)  215  may want to meet the sending user (“User A”). In this case, the local user (“User 1”)  215  would want to calculate a new route  1602  based on its own current location information  1601  and the desired meeting and/or destination points  1502  &amp;  1503  present in the received route  206 . A benefit of this invention is that all links  1603  in the route need not be re-calculated, but only the part of the received route  206  that has changed. 
     For example, the portion  1505  of the received route  206  (which consists of route points  1501 ,  1502 , &amp;  1503  and links  1505  &amp;  1603  as shown in  FIG. 16 ) between points  1501  and  1502  is the only portion of the route  1505  that needs to be recalculated, since the destination points  1502  &amp;  1503  are common between both users. Thus, a new link  1602  can be calculated based on the received route&#39;s first destination point  1502  and the local user&#39;s (“User 1”)  215  current location  1601  or preferred origin point. The rest of the route links  1603  can remain common between both users. Additionally, as shown in  FIG. 16 , the original received route  206  could be displayed in combination with the new route  1602  and the real-time location of both users  1504  &amp;  1601  along those routes can also be displayed. 
     In addition to having the capability to map roster list users and contacts, send location-relevant information and objects, such as POIs, routes, etc., and handle permission issues with sending and receiving said location-relevant information and objects, all using the real-time communication system  150 , this invention also has the capability to modify, create, and save routes using the real-time communication system  150 . As people skilled in the art will appreciate, modifying, creating, and saving routes via a real-time communication system  150  allows users to make use of mapping and routing applications not available in current or prior art. The following figures relating to routes assume the application is in a route-planner mode, except as otherwise noted, since some of the same actions that are used for sending and mapping POIs can also be utilized for modifying, creating, planning, and retrieving routes. 
     As illustrated in  FIG. 17 , a route  1708  is defined as a combination of destination points  1701 ,  1702 , &amp;  1703 , or an origin  1701  and one or more destination points  1702  &amp;  1703 . A map display  224  showing a pre-calculated route  1708  provides a user with a graphical illustration of the route, which provides better planning capabilities than standard driving directions or text information. Current prior art, such as Microsoft&#39;s MapPoint application, allows the ability to graphically add destination points to a pre-calculated route by selecting a point on the route and dragging-and-dropping the selected point to a new location in order to add a new destination point or change an existing one. As people skilled in the art will appreciate, using a real-time communication system  150  with a mapping application allows the capability to add users, contacts, or groups of users and contacts, using a graphical mechanism, to a pre-calculated route. In one embodiment, as shown in  FIG. 17 , a user can select  1704   a  user  215  from a roster list of users using a icon pointer  1705 . The user can then drag  1706  the selected user  215  to a point  1709  on the pre-calculated route  1708  to dynamically add a new destination point  1709  to the pre-calculated route  1708 , which corresponds to the current location information for the selected user which is obtained from the real-time communication system  150 . As an additional benefit, a user can select a point  1709  on a pre-calculated route  1708  using the icon pointer  1707  where a new destination point should be added, and drag  1706  that point  1709  with the icon pointer  1705  to a user, contact, or group of users and contacts in the messenger window  212 . 
     Once the selection in the messenger window  212  is highlighted  1704 , the icon pointer  1705  is dropped or released over the icon list representation for a user “User 1”  215 . This action would cause the current location information for “User 1”  215 , obtained using the real-time communication system  150 , to be added as a new destination point in the route  1708 . As people skilled in the art will appreciate, the real-time communication system  150  does not have to be used, since the location information can be retrieved locally, as is typically the case with a user&#39;s contact information. 
     Both of the previously described methods for adding a user, contact, or group of users or contacts to a pre-calculated route involve adding them to a portion of the pre-calculated route. In the provided embodiments, as shown in  FIG. 17 , this was between the pre-calculated route points “1”  1701  and “2”  1702 . The location information of the user, contact, or group of users or contacts can be incorporated into the route as a new destination point between these two points. The result is a system without the burden of recalculating the preferred order of destinations each time a new destination is added. The new destination is directly inserted in the proper order because the user is presented with the graphical representation of the pre-calculated route and has graphically identified the order position of the new destination point. The RTCMP  126  does not need to recalculate the entire route, but rather only the portion that was altered by the addition of the new destination. 
     Another aspect of this invention is allowing the user to directly add destinations, similar to the previous embodiments, except that the user selects  1801  the user, contact, or group of users or contacts with the icon pointer  1802  and drags  1803  the listing representation of the user “User 1”  215  to a route planner window  1710  and adds  1804  the selected  1801  user “User 1”  215  in the preferred destination order. Similarly, as illustrated before, the destination order is determined by the order that the user adds the new destinations to the route planner window  1710  or the position in which they are added if an origin  1701  and/or destination points  1702  &amp;  1703  already exist. For example, Los Angeles, Calif.  1701  is the origin, while Kansas City, Miss.  1702  is the second stop and New York, N.Y.  1703  is the final destination. When the user adds the location of the selected  1801  user “User 1”  215  in-between  1804  the origin  1701  and first destination  1702 , the route is-recalculated based on the new order and on the retrieved location-information of the user “User 1”  215  added to the route  1708  in the route planner window  1710 . The location information for user “User 1”  215  is retrieved using the real-time communication system  150 . 
     As illustrated in  FIG. 19 , the map display  224  shows a new route  1901  that includes the new destination point of Dallas, Tex.  1902 . The route planner window  1710  illustrates the added destination point of Dallas, Tex.  1902  as the first destination point (i.e., point #2), the order of which was determined by the point at which the dropping or releasing action occurred, typically by using a mouse click release or any other acceptable mechanism for releasing the element with the focus of the icon pointer  1804 , as shown in the previous figure. The origin and destination order of the route  1708  in the route planner window  1710  is follows that displayed in the map display window  224 . 
     In one embodiment, when the route planner window  2013 , as shown in  FIG. 20 , is open, the system is considered to be in a route-planning mode.  FIGS. 20-21  illustrate the addition of roster list users and POIs to a pre-calculated route using a graphical method. As shown in  FIG. 20 , a pre-calculated route  2004  is has an origin of Los Angeles, Calif.  2001  and destination points Kansas City, Mo.  2002  and New York, N.Y.  2003 . The origin and destination points are shown graphically on the map display  224  in the form of a route  2004  and in the route planner window  2013  in the form of a list. Both static POIs, whose positions are stored in the map data of the RTCMP  201  and dynamic POIs, which are graphical icon representations of roster list users whose position information is obtained using the real-time communication system  150 , can be selected on the map display  224  using a graphical method defined by this invention to graphically add origin and destination points to a pre-calculated route. 
     In one embodiment, a user can select  2006  a graphical icon representation of a user  2005 , whose position information is obtained using the real-time communication system  150 , then using the icon pointer  2006 , drag  2012  the icon representation of the user  2005  to a pre-calculated route  2004 . The point  2014  at which the user releases the selected object using the icon pointer  2007  is added to the pre-calculated route as a new destination point. Additionally, a user can select a static POI  2009 , such as a gas station, using the icon pointer  2008 , and drag  2013  the POI icon to the route planner window  2013  in order to add the new destination point in between the first  2002  and second  2003  destination points. Adding a new destination point can automatically recalculate the new route, or the user can initiate the new route calculation. Also, the user can drag  2011  the selected static POI  2009  to the pre-calculated route  2004  and add a new destination point to the pre-calculated route  2004  at the point  2015  where the POI icon was dropped by releasing the selected POI  2010 , which is done, as known to people skilled in the art, by a mouse click release, tap release, etc. 
     The newly added destination points can also be illustrated in the route planner window  2013  as italicized, indicating that they are to be added once the route has been recalculated. As shown in  FIG. 21 , the new route that was calculated in the previous example includes the new origin  2001  and destination points  2101 ,  2002 ,  2102 , &amp;  2003 . The new destination points that were added are shown in  FIG. 21  as San Jose, Calif.  2101 , which is the position of another user  2005  updated using the real-time communication system  150 , and Blacksburg, Va.  2102 , the position of the POI  2009 . It should be noted, and appreciated by those skilled in the art, that the only the links of the route that have changed are the ones that need to be recalculated and not the entire route. Under this example, the entire route needs to be recalculated. 
     Another benefit of this invention is illustrated in  FIG. 22 . In route-planner mode a user can select  2206  a POI  2205 , such as a gas station, and drag  2204  it to a graphical icon representation  2202  of a roster list user on the map display  224 , and then drop or release the icon pointer  2201  with the focus over the graphical icon representation  2202  of a roster list user in order to create a route from the location of that roster list user to the selected POI  2205 . Additionally, after having selected the POI  2205 , when the icon pointer  2201  is focused over the graphical icon representation  2202  of the roster list user on the map display  224 , the messenger window  212  icon listing of said user  220  will also highlight  2203 , as illustrated in  FIG. 22 . It should be noted that the location information of the roster list user whose graphical icon representation  2202  was selected was known and can be periodically updated using the real-time communication system  150 . The calculated route  2304  between “Vehicle 1”  2202  and the “Gas Station”  2205  whose address is in Pittsburgh, Pa. is displayed in the map display  224  of  FIG. 23 . Additionally, the route planner window  2303  illustrates the order of the origin  2301  and destination  2302  of the route  2304 . 
     As people skilled in the art will appreciate, multiple POIs can be added to the route  2304  using this approach, such that each POI, in this embodiment, is added as the last destination in the route  2304  and displayed as such in the route planner window  2303 . Additionally, this method of adding a destination to a route can be reversed, such that, in one embodiment, the graphical icon representation  2202  of the roster list user “Vehicle 1”  220  can be dragged onto a POI&#39;s graphical icon representation  2205  on the map display  224 . In this embodiment, the order of the destinations is chronological, according to the time a new destination point was added to the route  2304 . In both of these embodiments the route is dynamically calculated based on location updates from the real-time communication system  150 . 
     An added benefit of this invention is that the destination points of the previous embodiments do not have to be static POIs, but can be dynamic POIs that represent roster list users and the real-time communication system  150  can be used to obtain real-time location updates. One embodiment, shown in  FIG. 24 , includes two graphical icon representations  2403  &amp;  2406  of roster list users “Vehicle 1”  220  and “User 4”  218 , respectively. The selection of the graphical icon representation  2406  of roster list user “User 4”  218  causes the roster list window  212  list representation of “User 4”  218  to highlight  2407 . Dragging the select user  2406  using the icon pointer  2405  so that it is positioned over the graphical icon representation  2403  of roster list user “Vehicle 1”  220  causes the roster list window  212  representation of user “Vehicle 1”  220  to highlight  2402 . Once the graphical icon representation  2406  of roster list user “User 4”  218  is dropped or released onto the graphical icon representation  2403  of roster list user “Vehicle 1”  2403 , a real-time route between the first user  2406  (‘destination) and the second user  2403  (‘origin’) is created. Since the initial location information for both users are known, the real-time communication system  150  can be used when new position updates arrive, and then a new route is recalculated based on those new locations. Shown in  FIG. 25  is the route  2504  calculated between the graphical icon representations for the origin user  2403  and destination user  2406 . 
     The route planner window  2501  also shows the order of the route between the two users, where the origin  2502  is the location of “Vehicle 1”  220  and the destination  2503  is the location of “User 4”  218 . As people skilled in the art will appreciate, multiple destinations can be added to this route using both static (i.e., POIs) and dynamic (i.e., roster users) location-relevant objects, where the order, in this embodiment, of the new destination point is based on the order it was added. 
     Using this invention also allows for adding POIs to a route planner using a drag-and-drop method. In one embodiment, as shown in  FIG. 26 , a POI  2601 , such as a map identifier (i.e., city name of Pasadena), can be graphically selected using an icon pointer  2602  and using a dragging motion  2603  or some other accepted practice used by those in the art. The selected POI  2601  can then be dragged into a route planner window  2609 . The user can then use the icon pointer  2604  to drop the POI  2601  into the route planner window  2609 , where the focus of the icon pointer  2604  relative to the current origin  2606  and destination points  2607  &amp;  2608  determines the new order of the origin and destination points. For example, the POI  2601  was added to the end of the list of origin and destination points in the route planner window  2609 , thus causing this POI  2601  to be the last destination  2605  of the route, which can be either a pre-calculated or a previously-uncalculated route. 
     Illustrating the use of a combination of both static POIs and dynamic POIs, which represent roster list users, in the graphical creation of a route is further shown in  FIG. 27 . In one embodiment, with the program in a route mode operation, a user can create a route by selecting  2701  the icon list representation of a roster list user “User 1”  215  using an icon pointer  2702 . Then by dragging  2703  the roster list user icon list representation  215  to a graphical icon representation  2704  on a map display  224  and releasing it with the icon pointer  2705  focused over the destined objected  2704 , so that the destined object&#39;s  2704  roster list representation  223  is highlighted  2709  in the roster list window  212 . This action will add both objects to a route in the route planner window  2710 . 
     For instance, the origin  2711  is the location of the destined object  2704  of the drag  2703  operation, and the first destination point  2712  is the location of the roster list user  215 . The same process can be completed using a static POI  2707 , where the user selects the POI  2707  using an icon pointer  2708  and drags  2706  the icon pointer to the desired map object  2704 . When the icon pointer  2705  is focused on the desired map object  2704  on the map display  224  and then released both objects will be added to the route in the route planner window  2710 . Since the destination object is already the origin  2711  in the route planner, the POI  2707  is added to the end of the destination points  2713  in the route planner window  2710 . It should be noted that as location updates arrive using the real-time communication system  150 , the location of all points in the route planner window  2710  that are tied to the real-time communication system  150  could be updated accordingly. 
     In one embodiment as shown in  FIG. 28 , after all destination points have been added using this graphical system and method, and a route is computed, a route  2805  is displayed in the route planner window  2801  and on the map display  224 . The origin will be the user  2802  that was first selected and the first destination is that object  2803  upon which the first selected object was dropped. The second destination will be the POI  2804  that was added to the first selected object  2802 . Thus, the new route  2805  will display the origin and destination points  2802  &amp;  2803  &amp;  2804  in both the map display  224  and route planner window  2801 . 
     Another aspect of this invention, while in a route planner mode, allows an extremely efficient mechanism for creating routes to and from the local user&#39;s “User A”  213  current location. In one embodiment, for an in-vehicle navigation application, creating a route from the local user&#39;s “User A”  213  current location to the location of another user or contact simply involves selecting the local user&#39;s “User A”  213  roster list representation  213  with the icon pointer  2902 , which will cause it to be highlighted  2901 , and dragging  2905  it to another roster list user&#39;s list representation, such as “User 4”  218 . When the icon pointer  2904  is focused over the user&#39;s list representation  218 , as illustrated by it being highlighted  2903 , and then dropped or released a route  2914  from the local user&#39;s “User A” location to the user&#39;s “User 4”  218  location is created. Additionally, selecting local user&#39;s “User A” roster list representation  213 , which becomes highlighted upon selection, using the icon pointer  2902 , then dragging  2906  the icon pointer  2907  to the list representation of a contact  2909 , illustrated by the contact&#39;s list representation being highlighted  2908 , and finally dropping or releasing it will create a route  2911  from the local user&#39;s “User A” location to the location of “Contact 1”  2909 . Both of these embodiments can use the real-time communication system  150  for location updates. If both the user&#39;s and the contact&#39;s location information is stored locally or cached, then the real-time communication system  150  is not necessary. As illustrated in  FIG. 29 , the double arrows  2905  &amp;  2906  indicate that the dragging operation process can be reversed, and the contacts and other users can be selected and then dragged and dropped into the local user&#39;s “User A” roster list representation  213  with the icon pointer. 
     Other objects that can be used for route creation in an in-vehicle navigation system in route planner mode, such as shown in  FIG. 30 , include POIs or any graphical map object (i.e., map identifiers, users, etc.). In one embodiment, the local user&#39;s “User A” roster list representation  213  can be selected with the icon pointer  3002 , illustrated by the local user&#39;s icon representation  213  being highlighted  3001 , and then dragged  3003  and dropped using the icon pointer  3005  onto a POI  3004  in order to create a route. As illustrated in  FIG. 31 , a route  3105  is generated between the current location  3106  of “User A”  213  and the location of the POI  3104 . Additionally, the route planner window  3103  is updated to include both the origin  3101  and destination  3102  points. It should be noted that the origin could be a moving point when it represents an object whose location information is updated locally or through the real-time communication system  150 . 
     As people skilled in the art will appreciate, having a history trail based on a moving origin or destination points can provide a very necessary capability for graphically viewing location history trails based on real-world routes. In one embodiment, as shown in  FIG. 32 , an original route  3207  between an origin  3201  and destination  3202  is displayed in a route planner window  3210 . The original route  3207  that was created is shown in the map display  224 . As location updates arrive via the real-time communication system  150 , the origin location of “Vehicle 1”  3201  &amp;  220  changes thus changing its location on the map display  224 . 
     The new origin location on the map display  224  is shown  3205 , as well as the original destination point  3203 . Additionally, a new route  3208  is computed between the new origin  3205  and original destination  3203 . When the location of the origin  3201  changes again  3206  a new route  3209  will be computed based on the new origin location  3201  &amp;  3206  and the original destination  3202  &amp;  3203 . Instead of erasing the original route  3207 , it is displayed as a different color and pattern than the newly updated routes  3208  &amp;  3209 . In another embodiment, a legend can even be displayed to illustrate the pattern and color of the routes correlated with the time when they were updated. This route history allows the user to better graphically analyze the route information when using a dynamically updated route origin or destination.
