Patent ID: 8479121

Claim:
A sign object presentation device for a navigation system comprising: means for selecting object data for a three-dimensional object which includes presentation information and is a three-dimensional architectural object of a building or a monument; means for preparing multiple sets of sign data for one or more sign objects that can be shared between different locations; means for linking the object data with a plurality of simplified sign data of a sign object, which simplified sign data are obtained by simplifying ordinary sign data so as to simplify and capture the characteristics of the sign object to make viewing, by the user, easier and quicker; and simultaneously to provides better and precise individual identification of the sign object and the three-dimensional object, the ordinary sign data being an advertisement, or a color logo and shape either singly or in combination; means for selecting suitable sign data based on presentation information for when the object data is displayed on the presentation device; wherein presentation information comprises of: the size of the three-dimensional object, a viewing direction and information about overlapping of sign objects; information about overlapping of sign objects comprising of: means for determining if the sign data contains one or more logos and one or more shapes that when rendered on the device resulted in overlapping of one or more sign objects in the overall display and means for preventing overlapping on the three-dimensional object by scaling of sizes for sign objects and priority sequencing of sign objects; means for selecting proper simplified sign data out of the plurality of simplified sign data based on the presentation information for said object data; means for displaying the three-dimensional object with the selected simplified sign data together with the sign object located at a predetermined position of the three-dimensional object whereby a viewer can more easily, more quickly and more precisely identify the sign object and the three-dimensional object and means for increasing display speed of the presentation device by displaying simplified sign data based upon the collective data volume of simplified sign data.
