Abstract

The present invention relates to a navigation providing system. The present invention can prevent inconvenience that a user individually checks time required for multiple POIs in the navigation providing system by providing a route guidance to a specific POI after collecting traffic information on the multiple POIs from searched results related to a specific keyword and applying the collected traffic information to the multiple POIs. Also, the present invention can save time for searching the route and can be used conveniently since the user can selectively check only the POI that the user wants to check. If the arrival time to the destination is behind the estimated arrival time initially set during driving to the specific POI, the estimated arrival time is reset by recollecting the traffic information on the other selected POI; thereby providing a route through which the user can quickly arrive at the POI related to the inputted keyword.

Here, the terminal 10 displays a plurality of route information using traffic information and additional information in different colors on a map. In addition, the terminal 10 displays a plurality of route information using traffic information and additional information in the order of distance or scheduled arrival time.

Particularly, when the user of the terminal 10 according to the embodiment of the present invention has the voucher of a specific department store, it is possible to search for a list of nearby department stores related to the current position through keyword search using the department store name, A plurality of POIs are selected. That is, the terminal 10 selects various department stores according to the input of the user. At this time, the terminal 10 may provide a list of department stores by referring to the past history of route guidance or the search history of the user.

The terminal 10 collects traffic information or additional information for a plurality of POIs selected based on the search results thus provided, applies the collected traffic information or additional information to the POIs, and then transmits the POI It is possible to provide a route guidance by setting a specific POI selected from among the plurality of POIs as a destination.

Referring to FIG. 4, the terminal 10 for searching for a plurality of POIs during driving of the vehicle according to the present invention sets a specific POI as a destination in step S31, and when the vehicle is traveling using the corresponding route, Check the time. In step S33, the terminal 10 compares the estimated arrival time of the arrival time to the destination to determine whether or not the arrival is delayed.

If it is confirmed that the estimated arrival time is delayed, the terminal 10 displays a pop-up message on one side of the screen in step S35. For example, a pop-up message might say, "There is a delayed arrival time, use another POI?" Then, the terminal 10 checks whether a response to the pop-up message is received in step S37, and determines whether the confirmed response indicates agreement on the route re-search. If the user agrees to the route search, the terminal 10 requests the route search device 30 for route re-search for a plurality of POIs in step S39.

When a specific keyword (OO department store) is input to the input window, the terminal 10 provides a search result 501 related to the input keyword. At this time, the search results 501 are arranged in alphabetical order or distance according to the setting, and may be displayed on the screen including information such as name, address, and the like. Then, the terminal 10 transmits information about the keyword to the POI providing apparatus 20.

Then, the terminal 10 receives the path information 503 for a plurality of POIs to which traffic information is applied from the path search device 30, and outputs the received path information 503 to the screen. At this time, the distance information and the estimated arrival time to the POI may be displayed in the route information. In order to increase the reliability of the estimated arrival time, the terminal 10 may also display an event And combines the collected additional information and traffic information to calculate a scheduled arrival time to the destination.

The terminal 10 sets the POI corresponding to the specific route information 505 selected by the user as the destination among the plurality of route information 503 and performs route guidance to the destination.

As shown in FIGS. 6A to 6C, the terminal 10 confirms the initially arrived estimated arrival time and the expected arrival time at the current state while the vehicle is traveling along a specific route. If it is determined that the estimated arrival time from the current location 601 to the destination 603 is delayed compared to the estimated arrival time initially set, the terminal 10 displays a pop-up message 605 on the screen. At this time, the pop-up message is not displayed on the full screen so as not to interfere with the operation, but is provided to one side of the map information displayed through the navigation application. For example, a pop-up message might say, "Your estimated arrival time is delayed. Would you like to use another POI?" Can be displayed.

When the path resetting is requested in response to the pop-up message, the terminal 10 requests the path search device 30 for path search. The terminal 10 can confirm the time required until the POI is re-searched based on the current location 601, change the destination according to the user setting, and provide route guidance to the destination 607 .

While the specification contains a number of specific implementation details, it should be understood that they are not to be construed as limitations on the scope of any invention or claim, but rather on the description of features that may be specific to a particular embodiment of a particular invention Should be understood. Certain features described herein in the context of separate embodiments may be implemented in combination in a single embodiment. Conversely, various features described in the context of a single embodiment may also be implemented in multiple embodiments, either individually or in any suitable subcombination. Further, although the features may operate in a particular combination and may be initially described as so claimed, one or more features from the claimed combination may in some cases be excluded from the combination, Or a variant of a subcombination.

Likewise, although the operations are depicted in the drawings in a particular order, it should be understood that such operations must be performed in that particular order or sequential order shown to achieve the desired result, or that all illustrated operations should be performed. In certain cases, multitasking and parallel processing may be advantageous. Also, the separation of the various system components of the above-described embodiments should not be understood as requiring such separation in all embodiments, and the described program components and systems will generally be integrated together into a single software product or packaged into multiple software products It should be understood.

It should be noted that the embodiments of the present invention disclosed in the present specification and drawings are only illustrative of specific examples for the purpose of understanding and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.

The present invention collects traffic information for a plurality of POIs in a search result associated with a specific keyword, applies the collected traffic information to a plurality of POIs, and provides route guidance to a specific POI. Accordingly, it is effective in providing the route providing service because the navigation providing system searches and provides the interested information mainly on the estimated arrival time (time required) to which the actual traffic situation is applied. In addition, since it is not inconvenient to individually check the time required for various POIs, and it is possible to selectively check only the POIs that the user wants to check collectively, the time for route search can be saved and conveniently used. When the expected arrival time to the destination is delayed compared with the first scheduled arrival time while the specific POI is selected and traveled, the traffic information for the other selected POI is re-collected to reset the estimated arrival time, Provides a route to arrive at a POI that is relevant to the keyword quickly entered. This is not only a possibility of commercialization or sales, but also a possibility of being industrially applicable since it is practically possible to carry out clearly.
