Problems solved by technology

[0005] In perspective views, the pictograms of all POIs are usually displayed at the same size, regardless of their position in the perspective view, since making the pictograms smaller will make them unrecognizable
Therefore, the panoramic impression of the perspective view is degraded
Furthermore, it confuses and unclear to the user of the navigation device as to how far the POI has actually been located

Abstract

A method of displaying points of interest in a perspective view of a geographical area on a display of a navigation device is provided. In the method, a perspective view of the geographical area is displayed on the display of the navigation device. Further, points of interest are displayed as graphical symbols in the perspective view, wherein the size of each graphical symbol is dependent on the distance of the respective point of interest from a view point of the perspective view, such that graphical symbols for points of interest located further away from the view point are displayed smaller than graphical symbols for points of interest located closer to the view point. Each point of interest is associated with a point of interest-category.

Description

technical field [0001] The present invention relates to a method of displaying points of interest in a perspective view of a geographic area and a navigation device implementing such a method. Background technique [0002] Navigation systems are used to guide the driver of the vehicle to a destination. Other applications include use by pedestrians, cyclists, boat drivers and pilots to find a destination or to obtain information about the area they are traveling. For this purpose, modern navigation devices are equipped with a display on which the actual position of the navigation device and a geographical area in the vicinity of this position can be displayed. As an example, a map area, a satellite image or a topological image of an area can be displayed on the display of the navigation device. [0003] More advanced systems feature perspective views of geographic areas, which in simple cases include views from elevation angles over map areas, and in more complex cases may ...
