The key goal of Extended Reality (XR) is to offer the human users immersive and interactive experiences, notably the sense of being in a virtual or augmented environment, interacting with virtual beings or objects. A fundamental element in this goal is ...

This work presents an explorative behavioural analysis of users navigating in an immersive space aimed at enabling the next-generation multimedia systems. Our main goal is to understand how the user experience of immersive content with 6-Degrees-of-...

By means of vibrotactile and force feedback, i.e., haptics, users are given the sensation of touching and manipulating virtual objects in interactive Extended Reality (XR) environments. However, research towards the influence of this feedback on the ...

Extended Reality is a revolutionary method of delivering multimedia content to users. A large contributor to its popularity is the sense of immersion and interactivity enabled by having real-world motion reflected in the virtual experience accurately ...

Extended Reality is called to change human communications, in the same way that the telephone or the video call did. We are still at the beginning of the road, but the technology is already advanced and affordable enough to give us a glimpse of what XR ...

We consider a 6 Degree-of-Freedom (6DoF) immersive video streaming eco-system, which is composed of content creators, cloud service providers, and Head-Mounted Display (HMD) users. To avoid intellectual property leakage, content providers only offer ...

requirements such as high bandwidth (i.e., several Gbps) and low latency (i.e., five milliseconds). Today, most video-streaming applications leverage the transmission control protocol (TCP) for reliable end-to-end transmission. However, the reliability ...

Classically, rasterization techniques are performed for real-time rendering to meet the constraint of interactive frame rates. However, such techniques do not produce realistic results as compared to ray tracing approaches. Hence, hybrid rendering has ...

We present a first-of-its-kind end-to-end tele-robotic VR system where the user operates a robot arm remotely, while being virtually immersed into the scene through force feedback and holographic vision. In contrast to stereoscopic head mounted displays ...

Social communication is increasingly performed through video communication (VC) tools such as Teams or Zoom. Although VC is an effective way to maintain relationships remotely, it is still limited in creating a sense of social connectedness since the ...

Currently, most videoconferencing technologies do not keep employees sufficiently engaged during business meetings. Recent studies have shown how extended reality (XR) technologies can help in executing remote meetings in new and possibly better ways. ...
