BACKGROUND OF THE INVENTION

FIELD OF THE INVENTION

The present invention generally relates to navigation systems. More specifically, the present invention relates to a navigation system for scheduling multiple destinations. BACKGROUND OF THE INVENTION

Mobile devices are moving towards having access to larger amounts and varying types of information, either stored on the device itself or accessible to the device over a network. Many map-based applications available today are designed for a variety of different devices such as desktops, laptops, tablet devices, smartphones, handheld global positioning system (GPS) receivers, etc. and for various different purposes such as for navigation, browsing, sports, etc. Most of these applications generate displays of a map based on map data that describes relative locations of streets, highways, points of interest, etc., in the map. Some map-based applications provide a navigation feature, which provides the user with turn-by-turn instructions to a destination, which can be helpful while driving. However, the existing navigation applications designed to run on smart portable devices only allow the users to schedule one navigation map assisted journey at an instance. If the user wants to visit multiple destinations, he/she has to plan the journey and should sequentially enter the destinations one by one once the rides to each destination is completed.

Some other existing map based navigation systems provide various navigating functions and features to the end users, such as vehicle drivers. For example, some navigation systems are able to determine an optimum route to travel by roads between locations in a geographic region. Using input from the end user, the navigation systems can examine various routes between two locations to determine an optimum route to travel from a starting location to a destination location in the geographic region. The navigation system may then provide the end-user with information about the optimum route in the form of instructions that would enable the end user to travel from the starting location to the destination location. The navigation system may be located in an automobile, or in a portable device such as a navigation device or a smartphone and the instructions may take the form of audio instructions or visual maps that are provided as the end user is driving the route. Some navigation system are able to show detailed maps with real-time traffic and other related information on computer displays that outline routes to destinations, directions to be taken at various locations along the routes, locations of certain types of features, and so on.

There are certain prior arts such as US 20110166777 Al titled "Navigation application" filed by Anand Kumar disclose a mobile navigation device for route guidance. The mobile navigation device combines information related to the route guidance and a digital map display, which is updated to show travel related types of information in an easy to understand user interface. The navigation device includes a navigation application icon which when activated includes a weather indicator icon which, upon activation displays the weather with corresponding symbol icons that describes in picture form the current weather based on current user location, which is automatically updated, or any location that is specified by a user in a search bar located outside the digital map display. However, the above navigation application only allows the user to schedule one navigation map assisted journey at an instance. If the user wants to visit multiple destinations, he/she has to plan the journey and should sequentially enter the destinations one by one once the rides to each destination is completed. Another prior art US 20140365113 Al, titled "Navigation Application with Several Navigation Modes" filed by Apple Inc. discloses a method for providing navigation instructions on a device. The navigation application differently presents, in different navigation modes, the turn-by-turn navigation instructions and the turn-by-turn map views of a route between a starting location and an ending location. The different navigation modes include the driving mode and the pedestrian mode. As the device traverses a navigated route according to a first mode of transportation, the method displays a first turn-by-turn navigation presentation defined for the first mode. Based on data gathered by the device, the method determines that the device is navigating the route according to a second mode of transportation. The method automatically displays a second, different turn-by-turn navigation presentation defined for the second mode. However, the above navigation application only allows the user to schedule multiple modes of map-assisted journey and would not allow the user to perform journey involving multiple destinations using a single transportation mode such as using a car. According to the above cited method, if the user wants to visit multiple destinations, he/she has to plan the journey and should sequentially enter the destinations one by one once the rides to each destination is completed.

However, all these navigation applications allow the users to schedule only one navigation map assisted journey at a single instance. If the user wants to visit multiple destinations, he/she has to plan the journey and should sequentially enter the destinations one by one once the rides to each destination is completed. Hence there exists a need for an interactive navigation system that would allow the users to schedule multiple navigation map assisted journey at a single instance. The needed interactive navigation system would also provide optimal travel routes to the destinations. Further the needed navigation system would also allow the users to schedule for intermediate planned stops. Moreover the needed navigation system would allow the users to access external applications and in-map attractions through an interactive user interface of the navigation application running on the portable device.
