The present invention relates generally to the field of navigation data communication, and more particularly to systems and methods for sharing route information between a master device and subscriber device(s) within a group of travelers.
When a group of individuals are traveling to a common destination using independent navigation systems, each navigation system may plot different routes to the same destination, which allow the group to arrive at the same point, but not necessarily using the same route during the journey. Sometimes, the group would prefer to stay together for various reasons (e.g., safety, simultaneous travel, etc.). It is also possible that emergency stops, rest stops, and traffic conditions may contribute to the group of individuals becoming separated over time during the course of the route.
According to an embodiment of the present invention, a method for sharing route information is provided. The method comprises: requesting, by one or more subscriber devices, to join a route to a destination, created by a master device; receiving, by the one or more subscriber devices, updates to the created route to the destination from the master device; requesting, by a subscriber device from the one or more subscriber devices, a role change to a role of the master device; and responsive to a confirmation of the role change from the master device, configuring the requesting subscriber device to the role of the master device.
Another embodiment of the present invention provides a computer program product for sharing route information, based on the method described above.
Another embodiment of the present invention provides a computer system for sharing route information, based on the method described above.
A group of travelers in separate vehicles may want to stay together on a journey, which can sometimes be accomplished by entering the same destination in each navigation system within the group. However, factors such as traffic conditions, special configurations on the navigation systems, and different driving styles may lead to the group becoming separated over time. In addition, if one or more travelers takes a detour or rest stop, the other travelers may not know, or may not be able to reprogram their navigation devices while driving. Embodiments of the present invention provide systems and methods for a group of travelers to share route information and to stay together during the course of a journey to a same destination using independent GPS units, in which a ‘master/subscriber’ relationship is created between the navigation devices, allowing each ‘subscriber’ device to be routed to follow the same course, time, and waypoints as the master device.
The present invention will now be described in detail with reference to the Figures.
The term “operator” as used herein refers to the person using the navigation device. The operator may be a driver of an automobile, a hiker, a biker, an airplane pilot, a boat operator, or any other person capable of operating a navigation device. For purposes of the present disclosure, it is assumed that each of master device 120 and subscriber devices 130A-N has a different operator, it being understood that a subscriber device 130A-N can become the master device 120 at any point in time, and the master device 120 can become a subscriber device 130A-N (discussed in further detail below). For purposes of the present disclosure, it is assumed that each of master device 120 and subscriber devices 130A-N are located on or near an operator, or within a vehicle (e.g., automobile, airplane, boat, etc.) of an operator.
Master device 120 and subscriber devices 130A-N each include shared route program 105. In this exemplary embodiment, master device 120 and subscriber devices 130A-N are navigation devices. In various embodiments of the present invention, master device 120 and subscriber devices 130A-N can take the form of a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, a thin client, a wearable device, or any programmable mobile electronic device capable of executing computer readable program instructions. Master device 120 is a single navigation device within a group of navigation devices, which is charged with plotting the course, waypoints, and destination location. Subscriber devices 130A-N are one or more devices within a group of navigation devices, which receives route information from master device 120. In this exemplary embodiment, both master device 120 and subscriber devices 130A-N provide a user interface (not depicted in
Shared route program 105 is a software program which allows updates to be sent and received from each of master device 120 and subscriber devices 130A-N in real time. Shared route program 105 syncs the navigation devices, shares route codes, and receives the initial route details from central route server 140. Shared route program 105 can detect the distance between each of the other navigation devices and the created route, and can provide an option for switching the role of each device (e.g., the master device 120 can become a subscriber device 130A-N, and a subscriber device 130A-N can become the master device 120).
Network 110 can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, the public switched telephone network (PSTN), a mobile data network (e.g., wireless Internet provided by a third or fourth generation of mobile phone mobile communication), a private branch exchange (PBX), any combination thereof, or any combination of connections and protocols that will support communications between master device 120 and subscriber devices 130A-N, in accordance with an embodiment of the present invention. Network 110 may include wired, wireless, or fiber optic connections.
Central route server 140 includes route code store 142. Central route server 140 can receive a created route from a master device 120 and provide a unique route code to the master device 120. Each of subscriber devices 130A-N can look up the unique code in route code store 142. Central route server 140 can update all devices with a change to the route and can monitor the position of each device with respect to the created route. In response to detecting a sufficient deviation from the route by one of the navigation devices, central route server 140 can modify the route as needed. Central route server 140 can receive requests from devices to change the role of the devices (i.e., request for a subscriber to become a master) and can determine which device is the current master device, based on responses received from the devices (e.g., accept or deny a request to change a device role).
In step 202, a route creator uses a navigation device (i.e., the master device) to select a destination. In some embodiments, the route creator may be required to confirm a particular route to the selected destination.
In step 204, the route creator publishes the route. In this exemplary embodiment, the route creator may use an option on their navigation device to publish the selected route.
In step 206, the route creator secures the route. In this exemplary embodiment, the route creator may input a password to secure their route. In other embodiments, the route creator may specify which other travelers are invited or authorized to use the created route.
In step 208, the created route is uploaded to a central server and a unique route code is provided. In this exemplary embodiment, the navigation device of the route creator uploads the selected route to central route server 140, and central route server 140 confirms receipt of the route and provides the route creator with a unique route code. For example, the unique route code may be a URL.
In step 210, the route creator shares the unique route code with other travelers. In some embodiments, when other travelers have been preauthorized to access the route code (i.e., step 206), the route creator may simply invite the travelers to access the route code, without the need for a password to access the created route.
In step 302, a navigation device receives a unique route code, input by a traveler, such as a URL.
In step 304, the navigation device connects to the central server and looks up the entered route code. In this exemplary embodiment, central route server 140 requests a password or other type of authentication. The traveler must then enter the password that was shared by the route creator.
In step 306, a link is established between the subscriber device 130A-N and the master device 120 (i.e., the device used by the route creator to create the route), and the subscriber device 130A-N downloads the details of the created route from central route server 140.
In step 308, the subscriber device 130A-N receives route changes. In this exemplary embodiment, subscriber device 130A-N may receive route changes periodically as they are made or as they are updated by the route creator, from central route server 140. In some embodiments, the master device 120, as well as any synchronized subscriber device 130A-N can make an update to the route (e.g., request an unplanned stop, make a detour). The master device 120 can then accept or deny a request to update the route received from a subscriber device 130A-N.
Due to various real world conditions, such as traffic, operator skills, or speed of the various vehicles, the group of operators may or may not be within close proximity to each other. Embodiments of the present invention disclose two methods of keeping the group of operators together. In the first method, the master device's location is used as the destination, and establishes the location of master device 120 as the destination for subscriber devices 130A-N (i.e., the operational steps of
In step 402, the central server monitors the master device for a deviation from the intended route. In this exemplary embodiment, the master device constantly sends out current location updates to central route server 140. Central route server 140 receives these updates, and monitors the master device for position changes or deviations from the intended route.
In step 404, the central server determines whether a sufficient deviation from the intended route has been received. A degree of allowable deviation from the created route may be predetermined by the route creator, or may be a default setting on the navigation device. Central route server 140 monitors the distance between the master device 120 and the intended route, and detects when the predetermined, allowable degree of deviation from the intended route has been surpassed by the master device 120. For example, if the intended route is a freeway, and a 30 meter deviation is the allowable degree of deviation, then if the master device takes an unexpected deviation by exiting from the freeway and driving toward a gas station, the system will update the route on each of the other subscriber devices 130A-N to deviate toward the same gas station.
If central route server 140 determines that a sufficient deviation from the intended route has been received, then, in step 406, central route server 140 modifies the route, and sends the modified route to each synchronized subscriber device 130A-N. For example, if the master device decides to pull off a freeway and stop for gas, each of the other subscriber devices 130A-N will receive a waypoint modification or deviation that directs them off the freeway to the same gas station at which the master device has stopped. Thus, the master device's current location is the destination for each of the other subscribed travelers in the group.
In step 502, the master device 120 receives an update to the route. In this exemplary embodiment, the master device 120 includes a feature which allows the route creator to make updates to the route, while the route is in progress.
In step 504, the master device 120 sends the updated route to central route server 140.
In step 506, central route server 140 sends the updated route to each synchronized subscriber device 130A-N. For example, a master device 120 may want to have all subscribers to the route to get an update while the master device makes a momentary deviation (e.g., pulls off at a rest stop for a few minutes with plans to catch up later).
In other embodiments of the present invention, each of master device 120 and subscriber devices 130A-N may follow a different route to reach the same destination. For example, for a group of travelers each starting at a different location (i.e., their respective homes) and all meeting at the movies (i.e., the destination), shared route program 105 may synchronize the intended route, so that each of the travelers meets at the same destination at the same time (though each traveler has followed a different route). In this example, shared route program 105 is still able to coordinate rest stops or other travel conditions along the route, in order for each traveler to arrive at the destination at the same time.
In step 602, master device 120 receives an indication that a subscriber device 130A-N has passed the master device 120 by more than a threshold distance. In this exemplary embodiment, master device 120 continuously monitors each vehicle in the route caravan. If any vehicle in the route caravan passes the master device vehicle by greater than a predetermined threshold distance (e.g., 100 meters), then an indication is sent to the master device, as well as the device of the passing vehicle.
In step 604, master control is passed to the subscriber. In this exemplary embodiment, master control is automatically passed from the master device to the subscriber which has passed the master device's vehicle in the route. In some embodiments, the navigation device of the subscriber will provide an indication for the subscriber to accept the new master control. In this exemplary embodiment, the master control is passed to the subscriber who has physically passed the master device's vehicle, and this same rule (i.e., physically passing the master vehicle) will pass master control back to the original master device or another subscriber; otherwise the new master who first took the master role will indefinitely remain the master.
In step 606, the subscriber's position becomes the new master route destination. In this exemplary embodiment, if the vehicle systems are operating under the operational steps of
In step 702, central route server 140 receives a request from a subscriber to take over the master route. In this exemplary embodiment, a request is received at central route server 140 that a subscriber device 130A-N would like to become the master device 120. For example, a subscriber may request to take the master control by pressing a particular button, or providing a voice command.
In step 704, central route server 140 acknowledges the request from a subscriber, and sends an alert to the current master device. In this exemplary embodiment, an alert is sent to the master navigation device, requesting the master relinquish the route control to another subscriber. The master can then either confirm the request, or deny the request, by, for example, pressing a button or giving an audio/voice command.
In step 706, central route server 140 receives the response of the master device, and takes the appropriate action based on the response. For example, if, in step 704, the master device 120 confirmed the request to relinquish control to a subscriber device 130A-N, then central route server 140 determines that the subscriber now has the master control.
