Mulsemedia — multiple sensorial media — towards understanding user and quality of experience of future media applications

Niall Murray

Athlone Institute of Technology (AIT), Ireland

Abstract. Recently, there has been an emerging interest and research activity in in sensory technologies that stimulate all of the human senses vision, hearing, touch, smell, and taste. Critical to the success of such experiences is to understand how users perceive these ‘new’ enhanced multimedia experiences. Only by addressing this challenge systematically from technical and perceptual perspectives, can we meaningfully design multi-sensory multimedia experiences. In this talk, we provide an introduction to state of the art in Mulsemedia quality of experience (QoE) and user experience (Ux) research which considers different evaluation methodologies and approaches. The talk will also provide some discussion on the research carried by us through developing our own prototypes and executing user trials related to tactile, olfactory enhanced audio-visual experiences.

The art of saliency modeling for multimedia applications

Patrick Le Callet

Université de Nantes, France

Abstract. An extensive research work has been done in the last years to develop Visual Attention (VA) models for 2D, stereoscopic 3D images and videos or more recently for Virtual Reality and 360º. Reliable VA models are helpful in order to design efficient approaches for several applications, such as coding, streaming, foveated rendering, cinematography, movie editing, and Quality of Experience (QoE) evaluation. In this talk, I will review the current status on VA: advances and challenges from user study to modeling and benchmarking. A special focus will be dedicated to omnidirectional content. I will also illustrate how studying visual attention deployment of visual impaired people can help to improve VA computational modeling.

He led for ten years (2006-16) the Image and Video Communication lab at CNRS IRCCyN and was one of the five members (2013-16) of the Steering Board of CNRS IRCCyN (250 researchers). Since January 2017, he is one of the seven members of the steering Board the CNRS LS2N lab (450 researchers), as representative of Polytech Nantes. He is also since 2015 the scientific director of the cluster “Ouest Industries Créatives”, a five year program gathering more than 10 institutions (including 3 universities). “Ouest Industries Créatives” aims to strengthen Research, Education & Innovation of the Region Pays de Loire in the field of Creative Industries. He is mostly engaged in research dealing with the application of human vision modeling in image and video processing. His current centers of interest are Quality of Experience assessment, Visual Attention modeling and applications, Perceptual Video Coding and Immersive Media Processing.

Mulsemedia in 360 VR

George Ghinea

Brunel University, London

Abstract. Previous research has shown that adding multisensory media—mulsemedia—to traditional audiovisual content has a positive effect on user Quality of Experience (QoE). However, the QoE impact of employing mulsemedia in 360 videos has remained unexplored. Accordingly, in this talk, Prof. Ghinea is going to present results of a recently concluded QoE study for watching 360 videos—with and without multisensory effects—in a full free-viewpoint Virtual Reality.

Biography. Dr. Gheorghita (George) Ghinea is a Professor in Mulsemedia Computing in the Department of Computer Science, at Brunel University. Dr. Ghinea’s research activities lie at the confluence of Computer Science, Media and Psychology. In particular, his work focuses on the area of perceptual multimedia quality and how one builds end-to-end communication systems incorporating user perceptual requirements. To this end, recognising the infotainment duality of multimedia, Dr. Ghinea proposed the Quality of Perception metric as a more complete characterisation of the human side of the multimedia perceptual experience. Dr. Ghinea has applied his expertise in areas such as eye-tracking,telemedicine, multi-modal interaction, and ubiquitous and mobile computing, leading a team of 8 researchers in these areas. He has over 300 publications in his research field and is the lead Brunel investigator of a H2020 project NEWTON ( applying mulsemedia to STEM learning across Europe.


Hyperknowledge Graphs – Enabling Knowledge Graphs at scale with the Nested Context Model

Renato Cerqueira

Senior Research Manager, Natural Resources Solutions
IBM Research Brazil

Abstract. With the recent advances in Artificial Intelligence, the use of knowledge graphs is becoming pervasive. A new generation of AI-based applications is emerging, which relies on KGs to represent and manage knowledge. These KGs are consumed by advanced Machine Learning algorithms and reasoning engines. Despite of this increasing importance to the industry, there is a lack of methods and technologies to manage the lifecycle of KGs, especially to support reusability and maintainability. In this presentation we describe our work on the Hyperknowledge technology, which relies on the Nested Context Model to provide a flexible knowledge representation mechanism with high-level abstractions and expressiveness to enrich structure, enable reuse, and enhance interpretability.
