Dr.-Ing. Jan-Niklas Voigt-Antons


Jan-Niklas Voigt-Antons joined the Telekom Innovation Laboratories as a research scientist in January 2009 and is working there since 2014 as a senior research scientist. He received his diploma in psychology in 2008 from the Technische Universität Darmstadt, Germany, a Doctor-of-Engineering degree in 2014 from the Technische Universität Berlin, Germany and has been doing research at the Quality and Usability Lab at the Technische Universität (TU) Berlin, since. His research interests are in Quality-of-Experience evaluation and its physiological correlates with an emphasis on media transmissions and human-machine-interaction, including neural processing of multimodal interaction. During summer 2012 he was visiting researcher at MuSAE Lab (INRS-EMT), Canada where he examined neural correlates of quality perception for complex speech signals. In spring 2014 he was visiting researcher at the department of psychology of NTNU, Norway where he examined neural correlates of audiovisual asynchrony.

Abstract This study examines the effect of quality impairment on eye blink behavior as an indicator for fatigue while watching HD movies. Subjects watched eighteen minutes excerpts from a HD movie of sea-life scenes in original quality as well as with a reduced bitrate, a common impairment when streaming audiovisual material. Each six minutes, subjects rated the perceived video quality on a scale recommended by the International Telecommunication Union (ITU). Order of presentation was randomized across subjects. The version with reduced bitrate was rated to be of significantly lower quality than the high-quality version. Eye movements were recorded using electrooculogram (EOG), and blinks were extracted semi-automatically using freely available software for Matlab. All blink parameters were normalized subject-wise using the first two minutes of each video block as a baseline. While the interval between two blinks, i.e. the blink rate, showed no significant change between or within the videos, indicating comparable visual load across the sequences, average blink duration was significantly higher for the lower quality video, indicating a stronger fatiguing effect caused by the quality impairments. These results suggest that blink parameters can be deployed to assess the tonic effects of reduced video quality on the viewer.
