An Intelligent City Guide with a "Metal Detector" Interface

In this paper, we propose an intelligent location-aware city guide system which uses a “metal detector” interface for navigating users. Our system allows users to detect shops that match their preferences, in the same way an actual metal detector would be used to find metal objects. The procedure for finding shops that match users’ preferences includes a novel algorithm for learning frequented shops. Evaluation test results validate our overall approach.
