Positioning using Acceleration and Moving Direction

Abstract

The position of user or object is important context to provide the user with the user-oriented services. To position the user or object, we propose the autonomous positioning technique in this paper. In the autonomous positioning technique, the acceleration and the moving direction are used to position the user or the moving object. The moving length is calculated from the acceleration. And the calculated moving length and the direction is used to calculate new position of user or object. To show that the autonomous positioning technique is effective and useful, we implement the positioning device which uses the autonomous positioning technique. From the prototype implemented, we know that the proposed positioning is useful.
