Dr Alexander Marquardt presents research studies at the IEEE VR 2024

IEEE VR 2024, Orlando, USA - Dr. Alexander Marquardt präsentiert sein Paper

The IEEE Conference on Virtual Reality and 3D User Interfaces (IEEE VR) is the leading international event for the presentation of research results in the fields of virtual, augmented and mixed reality (VR/AR/MR) and took place this year in Orlando, Florida/USA. Postdoctoral researcher Dr Alexander Marquardt from H-BRS was able to present the results of his research on the topic of "Selection Performance and Reliability of Eye and Head Gaze Tracking Under Varying Light Conditions".

In collaboration with our alumnus Dr Martin Weier , now RheinMain University of Applied Sciences, as co-author, the team from H-BRS is conducting research in the DFG-funded project together with Dr Alexander Marquardt, Melissa Steininger and Christina Trepkowski from the Institute of Visual Computing (IVC) and Prof Dr Ernst Kruijff from the Department of Computer Science. Research in the field of augmented reality (AR) is increasingly focussing on refining user interaction by tracking eye and head movements, with their effectiveness influenced by environmental factors such as spatial layout and lighting conditions.

Abstract:
Augmented Reality (AR) applications increasingly rely on eye and head gaze tracking for user interaction, with their efficacy influenced by environmental factors such as spatial arrangements and lighting conditions. This paper presents two studies that examine how these variables affect the performance of eye and head gaze tracking in AR environments. While eye tracking partially delivered faster results, its performance exhibited greater variability, especially under dynamic lighting conditions. Conversely, head gaze tracking, while providing more consistent results, showed a notable reduction in accuracy in environments with fluctuating light levels. Furthermore, the spatial properties of the environment had notable implications on both tracking methods. Our research demonstrates that both spatial properties and lighting conditions are key determinants in the choice of a tracking method, underscoring the need for AR systems that can dynamically adapt to these environmental variables.

With his contribution, Marquardt and his team have made a valuable contribution to advancing the future of VR technology. The IEEE conference acts as an international hub for dialogue with visionaries in the field of VR and offers the opportunity to make international contacts with VR users and developers.
