Description

NAVIGATION APPARATUS PROVIDING UNIVERSAL SEARCH AND THE UNIVERSAL SEARCH PROVDING METHOD THEREOF}

The present invention relates to a navigation device for providing an integrated search and a method for providing an integrated search. In particular, a phone number search, a street address search, a road name address search, a name search, and a keyword search are performed through a single input interface in a single screen. The present invention relates to a navigation device for providing an integrated search and to an integrated search providing the integrated search.

The navigation device refers to a device that displays a current location of a vehicle on an electronic map using GPS.

Most recent vehicles are equipped with a navigation device so that the user can easily identify the current location of the vehicle or be guided through the route.

In order to receive a route using a navigation device, a destination must be input using a touch screen.

The destination can be searched by phone number, address, or name. When searching by address or name, a search can be performed by entering only a consonant or by entering an address or a name.

In the conventional navigation device, the user has to move to each separate search menu provided on the screen and use a search provided by the menu in order to input a phone number, address, name, etc. for the route search to the destination.

For example, in order to use a phone number search, it is inconvenient to select a phone number search menu and then use a phone number search or, in the case of an address search, to search by entering an address after selecting an address search menu.

In order to alleviate this inconvenience, some navigation devices have conventionally provided a menu that allows the navigation device to collectively search some types of destination searches by determining whether the user input is an address search or a name search.

However, such a search method is also cumbersome because it does not integrate the current destination input method as a whole, and the usability is low.

In addition, in recent years, the address system has been reorganized into a street name address that is different from the past address system, which is managed by the district number, and the old address system and the new address system are used interchangeably.

In such a situation, when a user searches for a destination on the navigation device, the user cannot intuitively know which search menu to select and search, making it difficult to search for a fast destination and inaccurate destination search accuracy.

Accordingly, there is a need for a navigation device that integrates a search such as a telephone number, an address number, a road name address, a name, and the like so that a user can easily search and increase usability through a single input area without a separate operation.

In addition, even if you do not know the name or location of the exact destination, you can easily search even if only a part of the information of the destination through the single input area above, providing a comprehensive search screen that improves the accuracy of the search A device is required.

1 is a flow chart of a method for providing a unified search according to an embodiment of the present invention.

Referring to FIG. 1, in the integrated search providing method, the integrated search providing method of the navigation apparatus 100 includes receiving an arbitrary user input for a search through a single input area within a screen (S10). The input is classified into one of a telephone number, an address, and a name. If the user input starts with a number, the input is classified as a telephone number (S20). If the user input includes letters and numbers, the input is classified as an address. Classifying the address or road name address according to a preset address classification criteria based on the preceding character (S40, S50), and if the user input is made of characters, classifying the name (S35, S60) and the user input. And performing a search for the classified type to display the results of the search (S30, S45, S55, S75).

In the integrated search providing method, a single search box is used to collectively search a keyword corresponding to a phone number, address, name, and destination according to a predetermined classification criterion through a single input area on a single screen. do.

In particular, when a user inputs an address through the single input area, the navigation device 100 automatically distinguishes and searches for an address number which is a current address system and a road name address which is a new address system.

According to a preferred embodiment, the navigation device 100 analyzes a user input entered through the single input area and starts with a number, and determines the number as a phone number.

At this time, if the user input does not start with '0', the navigation device 100 searches for a phone number by automatically adding an area code corresponding to the current location searched based on GPS before the contents of the user input (S30). )can do.

Alternatively, the user may provide a list of phone numbers nationwide including the phone number of the user input to the entire region without providing the area code automatically, thereby providing a result including various area codes.

On the other hand, the navigation device 100 is a conventional input if the user input in the single input area begins with a letter, including 'dong', 'ri', 'surface' or a combination of the corresponding first and number A search (S45) is performed based on the address number, which is an address system, and the search result is displayed on the screen.
