Abstract

This paper describes OpenTracker, an open software architecture that provides a generic solution to the different tasks involved in tracking input devices and processing tracking data for virtual environments. It combines a highly modular design with a configuration syntax based on XML, thus taking full advantage of this new technology. OpenTracker is a first attempt towards a "write once, track anywhere" approach to virtual reality application development. To support these claims, integration into an existing augmented reality system is demonstrated. Once development is sufficiently mature, it is planned to make OpenTracker available to the public under an open source software license. 1. Introduction Tracking is an indispensable requirement for all kinds of virtual reality (VR) and augmented reality (AR) systems. While the quality of tracking, in particular the need for high performance and fidelity have led to a large body of past and current research, little attention is typicall...
