Abstract

The location of a moving person or vehicle in a virtual reality environment is a critical issue. A wireless infrared sensor network capable of estimating the position of a target on a plane and its orientation is presented in this paper. This is actually an extension of the position estimation system that was presented in [1-2] where the target was allowed to move on a plane but not to rotate. In [1-2] the estimation of the position was based on a network consisting of a few low cost infrared transmitters and a pair of infrared receivers mounted on the target. In this paper we discuss how a third infrared sensor properly positioned at the side of the receiver can also allow the estimation of the target orientation.
