Introduction
I am a PhD candidate who is passionate about working with virtual reality. In particular, my work is focused on finding out how cybersickness is caused and how it can be prevented. I work mainly with immersive 360 videos which reproduce the reality in such a spectacular way that you can only be fascinated.

Virtual reality has ushered in a revolutionary era of immersive content perception. However, a persistent challenge in dynamic environments is the occurrence of cybersickness arising from a conflict between visual and vestibular cues. Prior techniques have demonstrated that limiting illusory self-motion, so-called vection, by blurring the periphera...
In this paper, we propose a wavelet-based video codec specifically designed for VR displays that enables real-time playback of high-resolution 360° videos. Our codec exploits the fact that only a fraction of the full 360° video frame is visible on the display at any time. To load and decode the video viewport-dependently in real time, we make use o...
Ours Reference HEVC AV1 Fig. 1: In this paper, we propose a wavelet-based video codec that is able to load and decode the data of 360°videos viewport-dependently by exploiting the properties of the wavelet transform. While the quality is on par with state-of-the-art video codecs, we can achieve significantly faster playback times. Here, a visual co...

Cybersickness often taints virtual experiences. Its source can be associated to the perceptual mismatch happening when our eyes tell us we are moving while we are, in fact, at rest. We reconcile the signals from our senses by using omnidirectional galvanic vestibular stimulation (GVS), stimulating the vestibular canals behind our ears with low-curr...
We investigate the mitigation of cybersickness (CS) in 360° videos, a phenomenon caused by the visually induced impression of ego-motion while being physically at rest. We evaluate the effectiveness of scene modulations to reduce motion in the peripheral visual field by deliberately blurring or opaque occluding eccentric view areas of up to ten deg...
Cybersickness is a unpleasant phenomenon caused by the visually induced impression of ego-motion while in fact being seated. To reduce its negative impact in virtual reality experiences, we analyze the effectiveness of two techniques-peripheral blurring and field of view reduction-through an experiment in an interactive race game environment displa...
Current facial reenactment techniques are able to generate results with a high level of photo-realism and temporal consistency. Although the technical possibilities are rapidly progressing, recent techniques focus on achieving fast, visually plausible results. Further perceptual effects caused by altering the original facial expressivity of the rec...
