Two-tier 360° video streaming provides a robust solution for handling inaccurate viewport prediction and varying network conditions. Within this paradigm, the client employs a dual-buffer mechanism consisting of a long buffer for panoramic basic-...

Understanding user visual attention (VA) is crucial for Field-of-View (FoV) prediction and resultant bandwidth optimization for 360° video streaming. The influence of spatial audio on VA has been largely overlooked. Traditional methods, using saliency, ...

360° videos have yielded satisfactory outcomes in English learning. However, there exists a dearth of research that delves into the efficacy of these videos for self-directed learning of English. This study aimed to investigate the factors that ...

This paper presents the resources utilized for and gathered from a subjective QoE experiment conducted with 45 participants who watched 360° videos processed with offline alignment edits. The aim of these edits is to redirect the assumed field of view to ...

Number of applications involving omnidirectional video's transmission from Unmanned Aerial Vehicle (UAV) are gaining popularity rapidly, ranging from remote surveillance to package delivery. Enabling these applications requires low-latency real-time ...

360° videos are gaining popularity, but immersive analytics, particularly in object detection, confront challenges from complex scenes and high data volume. This imposes significant burdens on individual users and resource-limited edge devices. ...

Although spherical video-based virtual reality (SVVR) has gained attention as an effective tool for technology-enhanced learning, little research has been conducted on its integration in formal education settings and the role of teachers in ...

• Research on the integration of SVVR into formal education and the pedagogical role of teachers therein is in its infancy.
• This DBR formulated apt pedagogic tactics for scaffolding students in SVVR-supported inquiry fieldwork-based ...

This work aims to present the first step of a creation of an instrument to assess memory deficits responding to the needs imposed by the inability to access clinical care, such as physical or geographical constraints or still limitations imposed ...

New technologies show promise for cultural and environmental sustainability. Yet the processes of production, use, and disposal of digital devices involve the exploitation of natural resources and human labor and have dramatic impacts on social systems ...

Intraoral radiography (IOR) practice education is essential for dental students. However, the risk of radiation exposure has resulted in the use of textbooks to learn IOR. Thus, a new educational tool that can effectively use fewer shots or ...

As a teaching and learning medium, 360° videos offer new teaching-learning experiences. Through the possibility of immersion, individual 360° panoramic images, multi-perspective viewing options and interaction possibilities, they extend the ...

Virtual tours in 360° video format are a modern way to destination marketing. The relevance of the study of innovative ways of promoting territories is determined by the process of digitalization of the economy and the high prevalence of digital ...

Virtual reality 360° video has an ultra-high resolution (usually 4–8 K), which takes more coding time than traditional video. Considering the degree of horizontal stretching in a different area of the ERP projected video, a fast coding unit (CU) ...

Blind people typically access videos via audio descriptions (AD) crafted by sighted describers who comprehend, select, and describe crucial visual content in the videos. 360° video is an emerging storytelling medium that enables immersive experiences ...

Virtual reality (VR) applications could be beneficial for education, training, and treatment. However, VR may induce symptoms of simulator sickness (SS) such as difficulty focusing, difficulty concentrating, or dizziness that could impair ...

Before caring for patients, video instruction is commonly used for undergraduate medical students, and 360° virtual reality (VR) videos have gained increasing interest in clinical medical education. Therefore, the effect of immersive 360° VR video ...

Omnidirectional videos capture environmental scenes effectively, but they have rarely been used for geometry reconstruction. In this work, we propose an egocentric 3D reconstruction method that can acquire scene geometry with high accuracy from a short ...

360° video has been becoming one of the major media in recent years, providing immersive experience for viewers with more interactions compared with traditional videos. Most of today’s implementations rely on bulky Head-Mounted Displays (HMDs) or ...

This paper contains the research proposal of Miguel Fernández Dasí that was presented at the MMSys 2022 doctoral symposium.¹ The production and consumption of multimedia content is continuously increasing, and this particularly affects to immersive ...

Immersive technologies are rapidly gaining traction across a variety of application domains. 360° video is one such technology, which can be captured with an omnidirectional multi-camera arrangement. With a Virtual Reality (VR) Head Mounted Display (HMD)...
