The lecture series for the INTERXR project “Virtual Education, Real Worlds?” began in the winter semester of 2025/26. This semester featured exciting lectures on the use of XR in university teaching as well as selected research topics.
On this page, you will find a collection of lecture recordings from the winter semester of 2025/26.

The immersive experience in XR: A media-psychological perspective
This presentation illuminates the core elements of immersive experiences from a media-psychological perspective. It then explores how these experiences, particularly in contrast to those offered by non-XR modalities, can support learning and educational objectives. XR causes an immersive experience, almost like in direct (non-mediated) experience. I posit that the immersive experiences, however, is inherently dualistic: it combines bottom-up perceptual presence, which reduces psychological distance, with an ongoing awareness that “this is just a simulation” (media awareness). This interplay influences users’ sense-making, emotional responses, and behaviors in XR. Presence and arousal are positively correlated, making XR more emotionally arousing than traditional 2D modalities – but XR can also impose a high cognitive load on users. Together, these characteristics prompt important considerations about the suitability of XR as a learning tool, including which types of learning and educational goals it may best serve, or where it may be less effective.

Visual perception aspects in VR and XR
How and what do I consciously perceive? The answer to this fundamental question largely determines whether and what content I can successfully learn. In VR environments, this question is particularly important, as non-visual means of controlling attention are often limited or even completely absent, such as acoustics and touch. In my presentation, I will highlight some fundamental aspects of our visual perception and how we can direct attention in VR.
