Configuration strategies of an AR toolkit-based wide area tracker

This paper deals with extending the AR Toolkit´s functionality to allow not only small stationary setups but wide range tracking applications as well. Based on a visionary scenario of a mobile user walking around in an intelligent building, we split the AR Toolkit´s functionality in several components based on our DWARF system. These components work together to allow a spatially distributed configuration of AR Toolkit´s marker detection code. The results of the marker detection are used to conclude changes in the mobile user´s coarse location. We present different strategies that could be employed for marker-based wide area tracking and discuss environmental factors influencing a good choice of strategy. We implemented the ideas discussed in this paper as part of a larger application and present results from this demonstration setup.
