Patent ID: 8743110

Claim:
An apparatus for generating a three-dimensional (3D) direction display, the apparatus comprising: a display configured to display a 3D map; and a controller configured to: display a predetermined path on the 3D map, and display a 3D direction display object during displaying the predetermined path for guiding a direction on a specific position of a guide point of the displayed path, the 3D direction display object being positioned above the displayed path; wherein a starting point of the 3D direction display object is moving on the predetermined path according to a distance between the apparatus and the guide point; wherein the 3D direction display object includes a plurality of interpolation point objects; and wherein when a distance between two interpolation point objects of the plurality of interpolation point objects is greater than a size of the 3D direction display, the controller is configured to calculate a remaining distance by subtracting the size of the 3D direction display from the distance and generate an additional interpolation point object at a location on the displayed path between the two interpolation point objects based on the remaining distance.
