US 8,798,903 B2 · Method and apparatus for detecting arrival at new city and producing information on new city

Abstract

An apparatus and method for a navigation system to detect arrival to a new city and provide information on the city such as dining, lodging, popular sightseeing place, etc. to the user. In addition, it can also provide the user a list of his or her friends in the new city according to an address book or from social networking websites. The navigation includes a detecting unit communicatively coupled with a position measuring device and a map information memory to detect whether the user is entering a new city by determining whether the user is moving across the new city border line. Further, the detecting unit indicates the user is entering a new city when the user is moving a predetermined distance away from an airport. Further, the new city information may not be shown if the user has visited the city before within a predetermined period.

Dependent claims

A portable navigation system comprises:

a display unit configured to display images for navigation operations including map images;
a position measuring unit adapted to receive information about current location of a user;
at least one database to store and provide maps, map attributes, road networks, geographical features, and point-of-interest (POI) information;
a detecting unit communicatively coupled with the position measuring unit and the database and configured to automatically detect whether the user is entering a new city selected based on a range of population;
and
an information providing unit configured to produce new city information
wherein the detecting unit causes to change the images on the display to a new city message screen when the user is entering a new city of the selected population range where the new city message screen is configured to allow the user to request new city information;
and
wherein the information providing unit causes to produce the new city information requested by the user on the display.

6 more elements

A method of providing new city information from a navigation device to a user comprises the steps of:

receiving a first position of the user;
storing the user's first position when the device is turned off, retrieving a user's second position when the navigation device is again turned on and comparing the user's second position with the user's first position stored in the device;
determining whether the user is entering a new city selected based on a range of population;
changing an image on a display unit to a new city message screen when the user is entering a new city of the selected population range where the new city message screen is configured to allow the user to request new city information;
and
displaying the new city information requested by the user on the display unit;
wherein the step of determining whether the user is entering a new city comprises a step of automatically detecting whether the user is entering the new city of the selected population range by a detecting unit communicatively coupled with a position measuring unit and a database.

4 more elements

An apparatus for providing new city information to a user comprises:

a user interface configured to display images including map images;
a position measuring unit to provide the user's current position;
an information providing unit;
and
a detecting unit,
wherein the position measuring unit stores a user's first position where the apparatus is turned off and retrieves a user's second position where the apparatus is again turned on, and the information providing unit is adapted to provide new city information to the user on the user interface when the user is entering a new city selected based on a range of population;
and
wherein the detecting unit which is communicatively coupled with the position measuring unit and at least one map database, causes to change the images on the user interface to a new city message screen when the user is entering a new city of the selected population range where the new city message screen is configured to allow the user to request new city information;
and
wherein the information providing unit causes to display the new city information requested by the user on the user interface.
