DYNAMIC GEOGRAPHICAL SPATIAL SEARCH
First Claim
1. Method for performing a dynamic special search for points of interest proximal to a path of travel of a moving user, the method comprising:
- detecting a position of the user;
detecting one or more attributes of the user'"'"'s movement or of a vicinity around the position of the user;
determining a new search region based on the user'"'"'s position and the one or more detected attributes, the new search region having a variable shape or size or both;
identifying an overlap region on the new search region with a previously determined search region;
reusing search results from the overlap region of the previously determined search region as part of point of interest search results for the new search region; and
calculating new point of interest search results only for a portion of the new search region outside of the overlap region.

Abstract
A method for performing a dynamic spatial search for points of interest proximal to a path of travel of a moving user. As the user moves along a path, a search is regularly conducted to provide updated information about points of interest for the user. The method includes automatically detecting a position of the user. One or more attributes of the user'"'"'s movement and/or of a vicinity around the position of the user are detected. To provide the updated search information a new search region is determined based on the user'"'"'s position and the one or more detected attributes. The new search region is compared to the previously determined search region to determine an overlap region that the two have in common. Search results from the overlap region are reused as part of point of interest search results for the current search region. New point of interest search results are calculated only for a portion of the new search region outside of the overlap region. Preferably, search results from the previously determined search region that are outside of the overlap are no longer needed and are discarded.
