Abstract: The extended field of view (FoV) offered by head mounted displays (HMD) increases the immersive experience, but it also introduces new visual quality challenges to be addressed. The judder artefact is a quality degradation factor that appears during object tracking and it is caused by eye movement relative to the display. As a first attempt to investigate the negative effect of judder in wide FoV applications, we built a new dataset of omnidirectional videos at different bitrates and judder severity levels. Two subjective tests were conducted to assess the quality in terms of perceived severity of judder in compressed video sequences. The outcomes provide new findings about the effect of judder on human perception. The results also give further understanding about the interaction between presentation quality and judder that can be utilized for developing objective models to predict quality degradation in presence of judder.
