This is the fifth time that TH Köln has conducted this study to examine the local XR industry´on behalf of Mediencluster NRW GmbH, a subsidiary of Film- und Medienstiftung NRW. Aside from the two surveys on the North Rhine-Westphalian sector, there have now been three studies on the nationwide XR (extended or cross reality) sector in Germany. By this we mean all companies that create products and services in the field of virtual, mixed or augmented reality (but not firms that employ XR as users).
This thesis proposes four different Augmented Reality (AR) display techniques that can overcome the problem of uncertain tracking errors. Where most other papers focus on limiting the amount of error that a user tracking system generates, this paper pro-poses visualizations that limit their impact instead. For this, four different display techniques have been developed and evaluated using criteria found in related literate. Two of the four proposed solutions consistently ranked better within these criteria. The first, Bending Words, uses a mix between spatially registered information and turn instructions to achieve that result. The second, WIM, mostly relies on context infor-mation of the building instead.
