ÑÇÖÞÉ«°É

I am particularly interested in potential synergies between these fields within different flavours of human-data interaction, such as beyond-the-desktop visualization and .

The above research topics can be explored in a variety of application domains, including Ocean Sciences, Environmental Sciences, Nuclear Sciences, Cultural Heritage, Learning and Education, Transport and Computer Games.Ìý

Ubiquitous, Immersive and Situated Analytics (IA/SA)

This theme explores the concept of ubiquitous, immersive, multisensory, post-WIMP and often situated visualization and investigates how information visualization can employ different display and presentation technologies, such as head-mounted displays, projection systems, wearables, tabletop displays and haptic interfaces.

We are a variety of technologies that could enable UA/IA/SA in different scenarios. We are especially interested in using (e.g., ), such as in our IA-prtototypingÌý and our more recent work on .

Immersive Realities (XR)

The use of the term ‘XR’ in this context is akin to that of the W3C, denoting alternative immersive technologies (i.e., VR/MR/AR). This theme explores these concepts and their evolution from their original graphic-centric flavours, to today’s XR systems which can employ all our senses and offer us capabilities through services that are perceivable but not necessarily vision-specific. Cloud-based services, web-based machine learning, XR-enabling web technologies and the pervasiveness of wearable and mobile devices, contribute towards this paradigm shift, which is the focus of this theme. More ‘traditional’ VR research, such as our work on Ìýand Ìýis also part of this domain.

Information Visualization (InfoVis)

Information visualization is the use of computer-supported interactive visual representations of abstract data to amplify cognition. In this theme we explore novel ways to represent data, focusing on domains such as environmental sciences, , and cultural heritage. We are also devising new methodologies for and evaluation of InfoVis interfaces.
