Abstract
Methods and systems for automatically adjusting a three-dimensional navigation system are provided. A method for automatically adjusting a display viewpoint for a three-dimensional navigation system may include receiving a velocity of a vehicle and a look-ahead distance between the vehicle and a look-ahead point, determining a range distance between the vehicle and the display viewpoint, determining the first position of the display viewpoint, displaying a three-dimensional view of a navigation route for the vehicle from the first position, receiving a change in the look-ahead distance, determining a new range distance, determining a second position of the display viewpoint, and automatically moving the position of the display viewpoint to the second position on a curvilinear swoop path located above and behind the vehicle. A corresponding system may include a navigation information collector, a range determiner and a display viewpoint adjuster.
