Abstract: A method and apparatus for entering an address for a navigation system allows a user to easily and quickly select a key indicating the next character of the address. At the start of operation, the navigation system shows a full alpha-numeric keyboard. Once the next candidate characters are narrowed down to a certain degree, the navigation system shows a simplified keyboard with a limited number of keys on the monitor screen and highlights the next candidate characters on the simplified keyboard. The navigation system displays both the simplified keyboard and a street name list on the same screen. Since the keys of the limited number are arranged within a small space such as in the three-by-three manner, the user can easily point a cursor or other pointing device to the desired key.

Abstract: A method and apparatus for improving efficiency and accuracy in event information exchange among users of navigation systems or other devices through wireless communication. The method includes the steps of: receiving information indicating an upcoming event, an event location, and participants thereof input by a user; checking a database storing data regarding types of event in response to the information input by the user to determine a type of the event; retrieving information regarding items required for the type of event determined and generating a template including a list of what items to bring by the participants of the event; and sending the template to the participants of the event through wireless communication.

Abstract: A map scrolling method and apparatus for a navigation system prevents from displaying certain icons while displaying other icons based on conditions and settings of the navigation system during a transition period of a map scrolling operation. The map scrolling method includes the steps of: detecting activation of a map scrolling operation; checking whether there is any limit condition attached to icons as to remove them from a map image; scrolling the map image while removing the icons to which the limit condition is attached from the map image during a transition period of the map scrolling operation; and displaying all of the icons when the map scrolling operation is completed.

Abstract: A method and apparatus for a navigation system automatically assigns or allows a user to assign a brand icon to a particular location. The navigation system displays the assigned brand icon as well as generic icons on a map image. Thus, the navigation system enables the user to quickly distinguish a particular place such as a point of interest (POI) from other similar type of POIs on a map image. The user can identify a particular chain restaurant from other restaurant by the brand icon unique to the particular chain restaurant on the map image so that the user can easily specify the favorite restaurant as a destination.

Abstract: A method and apparatus for automatically updating information on favorite places upon change of home address. The method includes the steps of: checking data received by the navigation system to detect whether the old home address of a user has been changed to the new home address; searching for favorite places around the new home address equivalent to that around the old home address; determining whether the updating of the favorite places should be conducted automatically or upon instruction by the user; updating the favorite places by replacing the favorite places for the old home address with the equivalent favorite places for the new home address; and repeating the above steps every time when there is a change in the home address.

Abstract: A display method and apparatus in a navigation system to provide lane complexity information is disclosed. In one embodiment, the navigation system provides guidance information by displaying one or more color indicators on each lane to indicate lane complexity thereon. The lane complexity can be determined by the number of freeways connected at an interchange or how many lane changes the driver has to make before approaching the maneuver point. In another embodiment, each lane on the map is highlighted with the same color as each color indicator which is located on or above the lane. In a further embodiment, a lane and an exit may be highlighted to differentiate from the lane which the vehicle is currently is travelling on to remind the driver of the exit.

Abstract: A information search method extends to a social networking site to search information by a contact name and other elements as location-based information, relationship, product, etc. The method includes the steps of receiving a search term specified by a searcher, detecting whether WHO is specified in the search term to determine whether search should extend to human contacts in social networking services, identifying WHAT from the search term and determining a nature of WHAT from the search term; sending the search term to a social networking service to retrieve relevant information; and presenting the retrieved information arranged in a predetermined order on a display or by audible sound and optionally a geographic information to retrieve information.

Abstract: A method and apparatus for selecting a desired point of interest (“POI”) for a navigation system displays matching brand icons associated with POIs to assist the user in finding an intended POI. When the user inputs characters indicating a POI name or a POI type, or selecting a POI type from a list, the navigation system displays brand icons of the POI name or POI type. When the user selects one of the brand icons, the navigation system lists the POIs associated with the brand icons in the predetermined order such as distance from the current vehicle position. Since the number of brand icons are limited, and each brand icon has a readily recognizable image, the user can quickly find a desired POI by selecting a brand icon.

Abstract: A method and apparatus of displaying a three-dimensional arrival screen allows the user to more easily and accurately identify the actual location of the destination by displaying the three-dimensional arrival screen which shows the relationship among the location of the destination, the locations of the neighboring addresses, and the current vehicle position. The method includes the steps of receiving a street address number of a destination, retrieving data indicating a road segment which includes the specified street address number, estimating positions of the destination and neighboring addresses based on street numbers of the destination, neighboring addresses, and position data of the road segment, and displaying a three-dimensional arrival screen when the user comes within the predetermined distance range from the destination.

Abstract: A navigation method and system determines a more accurate position of a street address number with use of building footprint information or latitude/longitude information of POI (point of interest), thereby accurately defining a position of a destination. When a user specifies a street address number as his destination, the navigation system retrieves the street segment that should include the location of the specified address number therein. The navigation system also checks the map data as to whether there is any building footprint data or POI position data associated with the street segment. The navigation system selects absolute locations on the street segment based on the building footprint data or the POI position data and determines the location of the specified address number by interpolating between two absolute locations.
