Patent ID: 6934705

Claim:
A computer-implemented navigation method for displaying point of interest (POI) information for selecting a destination, comprising the following steps of: specifying a category of POI in a navigation system for displaying a list of specified POIs; collecting a predetermined number (N) of POIs in an input data array; defining a number A of POIs to be contained in each block to produce a series of blocks each having the sorted POIs, where X is smaller than N, and a total number of blocks is N/(X−B); sorting the POIs by distance from a predetermined position in a forward order or a reverse order to produce a block of POIs sorted by distance where each block has A of POIs; displaying a list of POIs using the block of POIs sorted by distance and scrolling the list of POIs on a display screen in response to a scroll request; and repeating the above steps of sorting the POIs and displaying the POIs to produce another block of sorted POIs when the sorted POIs from previous sorting become insufficient for a further scroll request.
