Kurzfassung

While present-day Augmented Reality (AR) often focuses on the interaction and superimposition of clearly reachable objects, navigating vast, information-rich environments presents unique challenges, especially when virtual objects are distant, overlapping, or in complex surroundings. Crafting a solution that minimizes visual clutter while conveying essential information has yet to be fully realized. This thesis explores the application of AR for visualizing information-dense large areas like production halls. It addresses the limitations of existing AR solutions and proposes an approach using a predefined viewpoint as a vantage point. The implementation takes place in a factory shop floor, utilizing AR Head-Mounted Displays (HMD) for interactive data superimposition. Challenges include suitable tracking techniques, data visualization in large physical dimensions and user interaction with partly occluded information of various distant locations. A user study evaluates suiting interaction techniques and the overall utility. On the whole, this research aims to enhance visualization and interaction in industrial and architectural contexts. Results show that the system is perceived as helpful for its target application and that an overview 2D menu, due to its reliability is desired as an omnipresent option for interaction. For a better user experience, head gaze or eye tracking is preferred. Head Gaze enables more precise pointing while eye gaze tends to lead to a better experience, immersion and less physical effort. The widespread far hand ray interaction performed worst, because the exact movement was difficult to learn.
