“…In this sense, another aspect being analysed is the way of collecting the responses from the participants during the subjective test. Participants can rate the sequences using a controller or touchpad of the HMD [50], avoiding removing the goggles. Additionally, it can be recorded on a paper [30], verbally [35], [36], [51], [52], or online using a web application [53].…”

Recently an impressive development in immersive technologies, such as Augmented Reality (AR), Virtual Reality (VR) and 360°video, has been witnessed. However, methods for quality assessment have not been keeping up. This paper studies quality assessment of 360°video from the cross-lab tests (involving ten laboratories and more than 300 participants) carried out by the Immersive Media Group (IMG) of the Video Quality Experts Group (VQEG). These tests were addressed to assess and validate subjective evaluation methodologies for 360°video. Audiovisual quality, simulator sickness symptoms, and exploration behavior were evaluated with short (from 10 seconds to 30 seconds) 360°sequences. The following factors' influences were also analyzed: assessment methodology, sequence Manuscript received

“…Standardization of streaming 360-degree video is in progress. Recently, Curcio et al [43] have adapted ITU-T 2D and 3D video testing recommendations to 360-degree video in VR HMD, Tran et al [44] have assessed and categorized QoE aspects that affect 360-degree video streaming, and Pérez and Escobar [45] have proposed an assessment-aiding tracking tool for an upcoming ITU-T Recommendation for 360-degree VR video, ITU-T Rec. P.360-VR [46].…”

Joint effects of depth-aiding augmentations and viewing positions on the quality of experience in augmented telepresence

Virtual and augmented reality is increasingly prevalent in industrial applications, such as remote control of industrial machinery, due to recent advances in head-mounted display technologies and low-latency communications via 5G. However, the influence of augmentations and camera placement-based viewing positions on operator performance in telepresence systems remains unknown. In this paper, we investigate the joint effects of depth-aiding augmentations and viewing positions on the quality of experience for operators in augmented telepresence systems. A study was conducted with 27 non-expert participants using a real-time augmented telepresence system to perform a remote-controlled navigation and positioning task, with varied depth-aiding augmentations and viewing positions. The resulting quality of experience was analyzed via Likert opinion scales, task performance measurements, and simulator sickness evaluation. Results suggest that reducing the reliance on stereoscopic depth perception via camera placement has a significant benefit to operator performance and quality of experience. Conversely, the depth-aiding augmentations can partly mitigate the negative effects of inferior viewing positions. However the viewing-position based monoscopic and stereoscopic depth cues tend to dominate over cues based on augmentations. There is also a discrepancy between the participants' subjective opinions on augmentation helpfulness, and its observed effects on positioning task performance.

“…The authors also conducted a pilot project, showing the workflow of their application in a typical use case scenario. Similarly to [20], an Android VR application called MIRO360 was developed in [21]. This application is used to assess the subjective quality of ODVs using different methodologies that are being studied for the development of ITU-T P.360-VR recommendation.…”

This paper reports on the results of subjective testing of user Quality of Experience (QoE) for omnidirectional video (ODV) streaming quality. The test was conducted among 20 test subjects who watched three ODVs using a Head Mounted Display (HMD) system. The length of the videos was between two and three minutes. The first video was used for training purposes and contained no quality degradations. The quality of the other two ODVs was degraded by manipulating the resolution or by introducing different frame drop patterns. While watching the pre-prepared videos the subjects indicated if they noticed the changes in the quality and then rated it. After watching each video, the subjects completed a separate questionnaire, which evaluated their level of enjoyment and discomfort with the video. The results showed that the degradation of both objective parameters (video resolution and frame rate) impacted the subjects’ perception of quality; however, the impact was somewhat alleviated in ODV which contained dynamic scenes and fast camera movements.
