ABSTRACT
The science of motion tracking is fascinating because of its highly interdisciplinary nature and wide range of applications. This chapter will attempt to capture the interdisciplinary approach by organizing the subject differently from several excellent review articles already available (Bhatnagar, 1993; Ferrin, 1991; Meyer, Applewhite, & Biocca,1992; National Research Council, 1995). These reviews tend to break trackers into several technology categories and evaluate the merits of each technology by inferring from commonalties amongst the existing trackers in that category. This survey will instead focus on what capabilities are required for various applications and what are all the technologies and combinations that could potentially be used to realize these capabilities.
