Evaluation of Different Constructs: Media Quality, Simulator Sickness, and Presence

QoE for omnidirectional videos comprises additional components such as simulator sickness and presence. Besides media quality, also presence and simulator sickness need to be assessed for a holistic understanding of QoE. In this chapter, a series of tests is presented comparing different test protocols to assess integral quality, simulator sickness, and presence for omnidirectional videos in one test run, using the HTC Vive Pro as the head-mounted display. For quality ratings, the five-point ACR scale was used. In addition, the well-established SSQ and Presence Questionnaire (PQ) methods were used, once in a full version, and once with only one single integral scale, to analyze how well presence and simulator sickness can be captured using only a single scale. Furthermore, the inter-relation between the ratings for quality, presence, and simulator sickness is investigated.
