Towards XR communication for visiting elderly at nursing homes

Due to the current pandemic, the elderly in care homes are greatly affected by the lack of contact with their families, resulting in various mental conditions (e.g., depression, feelings of loneliness) and deterioration of mental health for dementia patients. In response, residents and family members increasingly resorted to mediated...

Multi-sensor capture and network processing for virtual reality conferencing

Recent developments in key technologies like 5G, Augmented and Virtual Reality (AR/VR) and Tactile Internet result in new possibilities for communication. Particularly, these key digital technologies can enable remote communication and collaboration in remote experiences. In this demo, we work towards 6-degrees of freedom (DoF) photo-realistic...

360-degree photo-realistic VR conferencing

VR experiences are becoming more social, but many social VR systems represent users as artificial avatars. For use cases such as VR conferencing, photo-realistic representations may be preferred. In this paper, we present ongoing research into social VR experiences with photo-realistic representations of participants and present a web-based...

WebVR meets WebRTC: Towards 360-degree social VR experiences

Virtual Reality (VR) and 360-degree video are reshaping the media landscape, creating a fertile business environment. During 2016 new 360-degree cameras and VR headsets entered the consumer market, distribution platforms are being established and new production studios are emerging. VR is evermore becoming a hot topic in research and industry...

Enabling 'togetherness' in high-quality domestic video conferencing

Low-cost video conferencing systems have provided an existence proof for the value of video communication in a home setting. At the same time, current systems have a number of fundamental limitations that inhibit more general social interactions among multiple groups of participants. In our work, we describe the development, implementation and...

Quantifying the quality of service of streaming media in differentiated services networks

Quality of Service (QoS) support in the current internet is indispensable because of QoS-sensitive real-time applications such as Voice-over-IP, IP-TV, video conferencing, online gaming etc. Since the introduction of the Differentiated Services (Diff-Serv) architecture there has been considerable work reported in literature on its performance...

Seeing is believing: Communication performance under isotropic teleconferencing conditions

The visual component of conversational media such as videoconferencing systems communicates important non-verbal information such as facial expressions, gestures, posture and gaze. Unlike the other cues, selective gaze depends critically on the configuration of cameras and monitors. Under isotropic videoconferencing conditions people see each...

Amino acid-catalyzed conversion of citral: Cis-trans isomerization and its conversion into 6-methyl-5-hepten-2-one and acetaldehyde

Under alkaline conditions, amino acids or proteins catalyze the deacetylation of citral, a major aroma component, resulting in methylheptenone and acetaldehyde formation. 3-Hydroxycitronellal is an intermediate in this reaction. Amino acids also catalyze the cis-trans isomerization of the pure isomers of citral, geranial, and neral. Most likely...
