Abstract
This paper describes a design, implementation and evaluations of a direction based service system named Azim, which utilizes both a position and a direction of a user. In this system, a user’s position is estimated by having the user point to and measure azimuths of several markers or objects whose positions are already known. Because the system does not require any other accurate position sensors nor positive beacons, it can be deployed cost-effectively. We have implemented a prototype system using a direction sensor that combines a magnetic compass and accelerometer. We have conducted experiments both indoor and outdoor, and exemplified that positioning accuracy by the proposed method is precise enough for a direction based service.
