Navigation system and displaying method thereof

摘要

Disclosed is a navigation system and displaying method thereof, which controls the level of protrusion for each piece of indication data displayed on a 3-D screen of the navigation system based on its criticality so as to maximize the legibility of the driver. More specifically, the navigation system includes a GPS receiving member which receives GPS location information, a map data storage member which stores map data including a plurality of indication data, a controlling member which requests a display scope of the map data, corresponding to the received GPS location information, and at least one set of indication data within the display scope, and 3-D data-processes said indication data so that it can be displayed so that the most important data is protruding the most to the driver, and a display member which displays the map data containing the 3-D data-processed indication data.

1. A navigation system comprising;
a GPS receiving member configured to receive GPS location information; a map data storage member configured to store multiple indication data including map data; a controlling member configured to request a display scope of the map data, corresponding to the received GPS location information, and at least one set of indication data within the display scope, and further configured to 3-D data-process the indication data so that it can be displayed so that a most critical data is protruding the most to a driver; a display member configured to display the map data containing the 3-D data-processed indication data based on a criticality level of the indication data; an indication data criticality setting member configured to set and store the criticality level of each piece of indication data; an indication data requesting member configured to request at least one set of indication data that falls within the display scope of the map data that corresponds to the received GPS location information; and a 3-D-data-processing member configured to match the requested indication data with an indication data criticality level and determine a particular level of protrusion in a direction of the driver based on the criticality level of the indication data, wherein the indication data is selected from a group consisting of information related to a speed of a vehicle, a speed limit of a road the vehicle is on, intersections, speeding radar, traffic camera locations, traffic information collector locations, Points of Interest (POIs) and bump locations, and wherein the information related to the speed of the vehicle, which is a part of the indication data, is displayed so that the speed of the vehicle protrudes in a direction of where the driver is seated, in proportion to how much faster than the speed limit the vehicle is moving.
