Measuring and comparing QoE and simulator sickness of omnidirectional videos in different head mounted displays. - In: 2017 Ninth International Conference on Quality of Multimedia Experience (QoMEX), ISBN 978-1-5386-4024-1, (2017), insges. 6 S.
In this paper, we evaluated and compared the integral quality of different omnidirectional contents for two head mounted displays (HMDs), namely HTC Vive and Oculus Rift. We also investigated motion sickness and head-movements. To this aim, we categorized omnidirectional contents into three categories based on the degree of motion: high, medium and low motion. For assessing simulator sickness, we used the Simulator Sickness Questionnaire for each of the contents in both HMDs. The viewing direction for subjects while watching the contents were recorded in terms of the three coordinates yaw, roll and pitch. Experimental results show that HTC Vive offers better integral quality compared to Oculus Rift. We also compared simulator sickness scores along with the behavioral data for different contents and HMDs and discussed the results in the paper.

A framework for QoE analysis of encrypted video streams. - In: 2017 Ninth International Conference on Quality of Multimedia Experience (QoMEX), ISBN 978-1-5386-4024-1, (2017), insges. 3 S.
Today most internet traffic is generated by video streaming. YouTube and other video streaming platforms are using encrypted streams (HTTPS) for transport of video content. Encryption will lead to more requirements on network and content providers, e.g. caching mechanisms will not work direct. Estimation of video quality for measuring users satisfaction is also harder because there is no direct access to the video bitstream. We are building up a framework for analyzing video quality that allows us to store client information, decrypted network traffic and encrypted messages. Our approach is based on a man-in-the-middle proxy for storing the decrypted video bitstream, active probing and traffic shaping. Using these data, we are able to calculate video QoE values for example using a model such as ITU-T Rec. P.1203. Our framework will be used for generating datasets for encrypted video stream analysis, analyzing internal behavior of video streaming platforms, and more. For experimental evaluation, in this paper we analyze the influence of our man-in-the-middle proxy on key-performance indicators (KPIs) for video streaming quality.
