METHOD OF DIRECTION-GUIDANCE USING 3D SOUND AND NAVIGATION SYSTEM USING THE METHOD
First Claim
1. A method of direction-guidance of a navigation system, the method comprising:
- detecting at least one of a proceeding direction in which a mobile vehicle is moving and a destination direction from a mobile vehicle to a destination based on navigation data;
calculating a proceeding angle and an angle of a destination direction of a mobile vehicle based on at least one of the detected proceeding direction and the detected destination direction of the mobile vehicle; and
generating a 3D direction-guidance sound having an angle corresponding to one of the proceeding angle and the angle of a destination direction using 3D sound technology.

Abstract
Provided are a method of voice-guidance and a navigation system that guide a travel route of a mobile vehicle using a 3D sound having directivity. The method includes detecting at least one of a proceeding direction and a destination direction of a mobile vehicle base on navigation data, calculating a proceeding angle of the mobile vehicle and an angle of a destination direction based on at least one of the detected proceeding direction and the destination direction of the mobile vehicle, and generating a 3D direction-guidance sound of corresponding angle by providing the calculated angles to 3D sound technology.

11. An apparatus for 3D guidance voice processing of a navigation system, the apparatus comprising:
-
a direction measuring unit which measures at least one of a proceeding direction and a destination direction of a mobile vehicle based navigation data; a sound angle setting unit which calculates a proceeding angle of the mobile vehicle or an angle of a destination direction of the mobile vehicle according to the proceeding direction or the destination direction of the mobile vehicle measured by the direction measuring unit, and which sets the proceeding angle of the mobile vehicle or the angle of the destination direction as a sound angle with respect to a corresponding direction; and a 3D sound generating unit which generates a 3D guidance sound of a corresponding angle by providing at least one of the angle of the proceeding direction and the angle of the destination direction set by the sound angle setting unit to 3D sound technology. - View Dependent Claims (12, 13)

14. An apparatus of direction-guidance of a navigation system, the apparatus comprising:
-
a proceeding direction measuring unit which measures an angle of a proceeding direction of a mobile vehicle and a distance between a current location and a changing point of direction of the mobile vehicle based on a current location of the mobile vehicle and a travel-route guidance signal; a destination direction measuring unit which measures a straight line direction from the current location of the mobile vehicle to a destination based on the current location of the mobile vehicle and the travel-route guidance operation; a sound angle setting unit which calculates a sound angle of a proceeding direction based on a distance between the current location and the changing point of direction and proceeding angles of the changing point of direction that are measured by the proceeding direction measuring unit, and sets a sound angle of the destination direction based on an angle difference between the current proceeding direction of the mobile vehicle and the destination direction that are measured by the destination direction measuring unit; and a 3D sound generating unit which generates a 3D guidance sound of a corresponding angle by providing at least one of the angle of the proceeding direction and the angle of the destination direction set by the sound angle setting unit to 3D sound technology. - View Dependent Claims (15)

16. A navigation system comprising:
-
a GPS module unit which receives location information from a plurality of GPS satellites, and calculates information on a current location of a mobile vehicle and a direction of travel of the mobile vehicle from the received location information; a map data storage unit which stores map data; a control unit which detects a current location of the mobile vehicle based on the information on the current location and the direction information input by the GPS module unit, matches the detected current location of the mobile vehicle with the map data stored in the map data storage unit, and determines a travel route for the mobile vehicle; a voice data storage unit which stores voice data related to the travel-route determined by the controlling unit; and a voice-guidance processing unit which measures a proceeding direction and a destination direction of the mobile vehicle using the current location of the mobile vehicle and the travel-route determined by the controlling unit, calculates a proceeding angle of the mobile vehicle according to the proceeding direction of the mobile vehicle and the destination direction of the mobile vehicle, and generates a 3D sound of a corresponding angle from the voice data stored in the voice data storage unit by providing the proceeding angle to 3D sound technology. - View Dependent Claims (17, 18)
