“…Immersiveness is another factor that needs to be considered in omnidirectional video QoE assessment, as the quality of the video can significantly improve the sense of presence in a VR environment. In order to do so, more factors than just picture quality need to be considered , as audio quality and spatial features can have a strong impact on sense of presence, as well as the proprioceptive matching between the user's movements and the video displayed on the HMD [104]. Multi-sensory environments [105] that include haptic feedback or even smells present yet more challenges: n [106], immersiveness is evaluated when an external sensory stimulus is combined to the omnidirectional video, finding that this kind of addition can improve immersiveness and enrich user experience.…”

The commercialization of Virtual Reality (VR) headsets has made immersive and 360 • video streaming the subject of intense interest in the industry and research communities. While the basic principles of video streaming are the same, immersive video presents a set of specific challenges that need to be addressed. In this survey, we present the latest developments in the relevant literature on four of the most important ones: (i) omnidirectional video coding and compression, (ii) subjective and objective Quality of Experience (QoE) and the factors that can affect it, (iii) saliency measurement and Field of View (FoV) prediction, and (iv) the adaptive streaming of immersive 360 • videos.The final objective of the survey is to provide an overview of the research on all the elements of an immersive video streaming system, giving the reader an understanding of their interplay and performance.

“…The spatial presence increases the sense of immersion in a VR scene. Zou et al [221] presented a subjective framework to measure the spatial presence of the twenty-five subjects experiencing 360 • videos on HMD and monitor. The proposed system framework consists of three layers from top to bottom, i.e., spatial presence layer, perception layer, and technical influencing factors layer.…”

Omnidirectional or 360 • video is increasingly being used, mostly due to the latest advancements in immersive Virtual Reality (VR) technology. However, its wide adoption is hindered by the higher bandwidth and lower latency requirements than associated with traditional video content delivery. Diverse researchers propose and design solutions that help support an immersive visual experience of 360 • video, primarily when delivered over a dynamic network environment. This paper presents the state-of-the-art on adaptive 360 • video delivery solutions considering end-to-end video streaming in general and then specifically of 360 • video delivery. Current and emerging solutions for adaptive 360 • video streaming, including viewport-independent, viewport-dependent, and tile-based schemes are presented. Next, solutions for network-assisted unicast and multicast streaming of 360 • video content are discussed. Different research challenges for both on-demand and live 360 • video streaming are also analyzed. Several proposed standards and technologies and top international research projects are then presented. We demonstrate the ongoing standardization efforts for 360 • media services that ensure interoperability and immersive media deployment on a massive scale. Finally, the paper concludes with a discussion about future research opportunities enabled by 360 • video.

“…Bireylerin sanal gerçeklik ortamında deneyimledikleri var olma durumunu ifade eden bulunma hissi üzerine çok sayıda araştırma yürütülmüştür. Bu çalışmalarda bulunma hissinin önemine değinilmekte ve sanal gerçeklik teknolojisini benzersiz yapan özelliklerden biri olduğu ifade edilmektedir (Borrego, Latorre, Alcañiz ve Llorens, 2019;Grabarczyk ve Pokropski, 2016;Zou, Yang, Zhang, Li ve Yu, 2018). Öyle ki, literatür incelendiğinde son dönemlerde yapılan birçok sanal gerçek araştırmasının bulunma hissini odak noktasına koyarak, konuyu farklı açılardan ele aldığı ve bu kavramı sanal gerçeklik ortamlarının anahtar öğelerinden biri olarak kabul ettiği görülmektedir (Kern ve Ellermeier, 2020;Kritikos, Zoitaki, Tzannetos, Mehmeti, Douloudi, Nikolaou, Alevizopoulos ve Koutsouris, 2020;Servotte ve diğerleri, 2020;Weech, Kenny ve Barnett-Cowan, 2019).…”

Sanal gerçeklik bireylerin mevcut fiziksel gerçeklikten koparak farklı dünyalar deneyimleyebilmelerini sağlayan önemli bir teknolojidir. Katılımcıların sanal gerçeklik ortamlarındaki tamamen var olma durumu literatürde bulunma hissi ya da bulunuşluk olarak ifade edilmektedir. Bu çalışmada Türkçe literatürde yaşanan eksikliği giderebilmek amacıyla bireylerin sanal gerçeklik ortamlarında yaşadıkları bulunma hissi üzerine gerçekleştirilen araştırmaların sistematik ve kapsamlı bir analizi yapılmıştır. Çalışma bu yönüyle bir sistematik derleme araştırmasıdır. Altı farklı veri tabanında yapılan taramalar neticesinde elde edilen açık erişime sahip 1167 çalışma üç aşamalı bir eleme sürecine tabi tutulmuş ve doğrudan bulunma hissi ile ilgili olan 56 çalışmanın sonuçları; bilişsel -psikolojik incelemeler, teknik incelemeler, duyusal incelemeler ve teorik -analiz incelemeleri başlıklı dört tema altında derlenmiştir. Araştırmanın sonuç bölümünde bulunma hissi üzerine çıkarımlar yapılarak kavramın önemli noktaları vurgulanmış ve gelecek çalışmalar için önerilerde bulunulmuştur.
