The current study aims to evaluate and compare the subjective quality of an AI-based training system developed for conducting child interviews, focusing on the distinction between immersive 3D (using virtual reality) and 2D desktop environments. To this ...

Virtual reality applications are witnessing increased adoption in mental and physical health fields, from rehabilitation therapies to psychological studies. The more advanced the application, the greater the demand to incorporate realistic, custom ...

The rapid expansion of virtual environments, particularly Massively Multi-user Virtual Environments (MMVEs), presents significant challenges in scalability and performance. Traditional Client/Server and Client/Multi-Server architectures often encounter ...

Inside-out tracking is growing popular in consumer VR, enhancing accessibility. It uses HMD camera data and neural networks for effective hand tracking. However, limited user experience studies have compared this method to traditional controllers, with ...

Virtual reality (VR) has the potential to transform work, collaboration, and socialization in diverse settings. Nevertheless, most immersive interactions are inaccessible to individuals who use one hand, as their design assumes that VR users have ...

The use of 360° content with sensory effects can enhance user immersion. However, creating such effects is complex and time-consuming as authors must annotate the spatial position (i.e., "origin of the effect") in 360°. To tackle this mutimedia authoring ...

In recent years, a large variety of online communication tools have emerged, including social Virtual Reality (VR) platforms for interacting in a virtual world with participants being represented as virtual avatars. Given their popularity, an active area ...

The recent development of new video capture systems has led to the adoption of volumetric video technologies to replace 2D video in use cases such as videoconference, where this enhancement promises to solve videoconference fatigue. In particular, ...

The quality-bitrate relationship is not necessarily as straightforward in volumetric video content as in 2D video. This is caused by the different volumetric video components affecting the overall quality of the content disproportional to their bitrates. ...

This work tackles the challenge of predicting human trajectories while carrying out complex tasks in contextually-rich virtual environments. We evaluate the CREATIVE3D multimodal dataset on human interaction and navigation in 3D virtual reality (VR). In ...

Volumetric video, which is typically represented by 3D point clouds, requires efficient point cloud compression (PCC) technologies for practical storage and transmission. Particularly, developed by the Moving Picture Experts Group (MPEG), video-based PCC ...

Volumetric video, a technique used in augmented reality (AR) and virtual reality (VR) applications, presents unique challenges in rendering and compression. To enable efficient compression, video-based point cloud compression (V-PCC) techniques have been ...

Progressive coding is a valuable technique for networked immersive media. As users approach objects in an immersive environment, progressive coding enables a gradual improvement of content quality. This effectively reduces bandwidth consumption compared ...

Volumetric video offers immersive exploration and interaction in 3D space, revolutionizing visual storytelling. Recently, Neural Radiance Fields (NeRF) have emerged as a powerful neural-based technique for generating high-fidelity images from 3D scenes. ...

With NeRF, neural scene representations have gained increased popularity in recent years. To date, many models have been designed to represent dynamic scenes that can be explored in 6 degrees-of-freedom (6-DoF) in immersive applications such as virtual ...
