1. A method for navigating in a particular area, the method comprising: downloading from a network into a computing device an artistic map, the artistic map being non-linearly scaled and including various objects being exaggeratedly shown on the computing device to facilitate a user using the computing device to view and select one of the objects to navigate thereto in the artistic map, wherein the computing device is portable, equipped with navigation capability and provides a traveling guidance based on a geographical map, the artistic map is not used directly by the computing device for navigation, each of the objects is represented by a plurality of points on a display of the computing device, and the geographical map is not being displayed on the display; receiving in the computing device a selection on the one of the objects from the user as a selected object; determining by the computing device a pair of coordinates for one of the points on the selected object; transforming in the computing device the pair of coordinates to a physical point represented by a pair of latitude and longitude in the geographical map not being shown on the display, the points representing the selected object having different pairs of coordinates, but all of the different pairs of coordinates for the selected object corresponding substantially to the physical point when said transforming is performed; detecting a current location of the computing device in the geographical map; determining according to the geographical map a navigational direction from the current location to the one of the objects being selected; and showing the navigational direction on the artistic map being displayed.
