Subjective Evaluation of Visual Quality and Simulator Sickness of Short 360$^\circ$ Videos: ITU-T Rec. P.919

Recently an impressive development in immersive technologies, such as Augmented Reality (AR), Virtual (VR) and 360${^\circ }$ video, has been witnessed. However, methods for quality assessment have not keeping up. This paper studies of video from the cross-lab tests (involving ten laboratories more than 300 participants) carried out by Immersive Media Group (IMG) Video Quality Experts (VQEG). These were addressed to assess validate subjective evaluation methodologies video. Audiovisual quality, simulator sickness symptoms, exploration behavior evaluated with short (from 10 seconds 30 seconds) sequences. The following factors’ influences also analyzed: methodology, sequence duration, Head-Mounted Display (HMD) device, uniform non-uniform coding degradations, methods. obtained results demonstrated validity Absolute Category Rating (ACR) Degradation (DCR) videos, possibility using 10-second videos (with or without audio) when addressing artifacts, well any commercial HMD (satisfying minimum requirements). Also, efficient long Simulator Sickness Questionnaire (SSQ) proposed evaluate related symptoms videos. instrumental ITU-T Recommendation P.919. Finally, annotated dataset is made publicly available research community.
