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.
