We present a method to implement a location-aware information browser on mobile phones. Our location-aware information browser is designed to look for nearby hidden points of interests in mobile computing environments. The method we developed provides two benefits: The first benefit is to improve the performance of transforming and rendering a map by combining filtering techniques of a spatial database and fixed-point arithmetic techniques. Our method is designed to deal with two kinds of minimum bounding rectangles to apply such conventional effective processing techniques of a spatial database to our browser. The second benefit is to handle large or long map elements in BREW-based computing environments by clipping techniques of computer graphics. We clarified the feasibility and effectiveness of our method by several experiments.
