Omnidirectional (also called 360-degree) videos are panoramic spherical videos in which the user can look around during playback and which therefore can be understood as hybrids between traditional movie streaming and interactive VR worlds. Unfortunately, streaming this kind of content is extremely bandwidth intensive (compared to traditional 2D video) and therefore, Quality of Experience (QoE) tends to deteriorate significantly in absence of continuous optimal bandwidth conditions. In this paper, we present a first approach towards subjective QoE assessment for omnidirectional video (OV) streaming. We present the results of a lab study on the QoE impact of stalling in the context of OV streaming using head-mounted displays (HMDs). Our findings show that subjective testing for immersive media like OV is not trivial, with even simple cases like stalling leading to unexpected results. After a discussion of characteristic pitfalls and lessons learned, we provide a a set of recommendations for upcoming OV assessment studies.}, doi = {10.1109/QoMEX.2017.7965657}, isbn10 = {978-1-5386-4024-1}, issn = {2472-7814}, language = {EN}, location = {Erfurt, Germany}, pdf = {https://www.itec.aau.at/bib/files/QoMEX_2017_paper_44.pdf}, talkdate = {2017.06.01}, talktype = {registered} } @InProceedings{Timmerer2010_ACMMM_SensoryExperience, author = {Timmerer, Christian and Müller, Karsten}, booktitle = {Proceedings of the International Conference on Multimedia (MM '10)}, title = {Immersive Future Media Technologies: From 3D Video to Sensory Experiences}, year = {2010}, address = {New York, NY, USA}, editor = {del Bimbo, Alberto and Chang, Shih-Fu and Smeulders, Arnold}, month = {oct}, pages = {1781--1782}, publisher = {ACM}, abstract = {In this tutorial we present immersive future media technologies ranging from 3D video to sensory experiences.
