| 20110285717 | METHOD FOR GENERATING MANOEUVRE GRAPHICS IN A NAVIGATION DEVICE - A technique for controlling a navigation device to generate a navigation manoeuvre graphics for a road junction manoeuvre is proposed. A device embodiment of this technique comprises a routing module adapted to provide routing information pertaining to a scheduled route, with the scheduled route comprising the road junction. Furthermore, an interface to a map database is provided, with the map database containing road data pertaining to the upcoming road junction. A processor of the navigation device analyses the road data to determine one or more junction geometry parameters of the road junction and to compose, based on the junction geometry parameters and from a plurality of pre-defined graphical junction elements, junction graphics data representative of the road junction. The processor is further adapted to generate, from the routing information and the junction geometry parameters, manoeuvre indication graphics data representative of the junction manoeuvre. A display module may then render navigation manoeuvre graphics based on the junction graphics data and the manoeuvre indication graphics data. | 11-24-2011 |
