This book presents extensive research on the quality of 360{deg} video perceived by users with HMDs. The book aims to develop a set of standard guidelines for the systematic visual quality assessment of 360{deg} videos. Firstly, conventional subjective test methods such as Absolute Category Rating (ACR) and Double Stimulus Impairment Scale (DSIS) are applied to evaluate video quality, alongside the Modified ACR (M-ACR) method newly proposed. Building on the reliability and general applicability of the procedure across different tests, a methodological framework for 360{deg} video quality assessment is then presented. The author also analyzes simulator sickness to investigate the impact of different influencing factors. The insights gained on simulator sickness related to 360{deg} video contribute to a better understanding of this particular use case of VR and can help to improve comfort among users by suggesting improvements in the technical specifications of 360{deg} video and HMD technology and thus improving QoE. Presents extensive research on the quality of 360{deg} video perceived by users with HMDs; Develops a set of standard guidelines for the systematic visual quality assessment of 360{deg} videos; Analyzes simulator sickness to investigate the impact of different influencing factors.
