We present Deimos, a grammar for specifying dynamic embodied immersive visualisation morphs and transitions. A morph is a collection of animated transitions that are dynamically applied to immersive visualisations at runtime and is conceptually modelled as a state machine. It is comprised of state, transition, and signal specifications. States in a...

Recent studies have explored how users of immersive visualisation systems arrange data representations in the space around them. Generally, these have focused on placement centred at eye-level in absolute room coordinates. However, work in HCI exploring full-body interaction has identified zones relative to the user's body with different roles. We...

In immersive environments, positioning data visualisations around the user in a wraparound layout has been advocated as advantageous over flat arrangements more typical of traditional screens. However, other than limiting the distance users must walk, there is no clear design rationale behind this common practice, and little research on the impact...

Immersive Analytics has now fully emerged as a research topic in the Visualisation and Human-Computer Interaction research communities. While evidence of its benefits has been accumulating, we have still attained only a basic understanding of the extent to which they can support human sensemaking, This workshop aims to define a roadmap for new dire...

As mixed-reality (MR) technologies become more mainstream, the delineation between data visualisations displayed on screens or other surfaces and those foating in space becomes increasingly blurred. Rather than the choice of using either a 2D surface or the 3D space for visualising data being a dichotomy, we argue that users should have the freedom...

Immersive Analytics is now a fully emerged research topic that spans several research communities, including Human-Computer Interaction, Data Visualisation, Virtual Reality and Augmented Reality. Immersive Analytics research has identified and validated benefits of using embodied, 3D spatial immersive environments for visualisation and have shown b...

This study analyzed and explored the cognitive load of Australian energy market operators managing one of the longest inter-connected electrical networks in the world. Each operator uses a workstation with seven screens in an active control room environment, with a large coordination screen to show information and enable collaboration between diffe...

We propose TimeTables, a novel prototype system that aims to support data exploration, using embodiment with space-time cubes in virtual reality. TimeTables uses multiple space-time cubes on virtual tabletops, which users can manipulate by extracting time layers or individual buildings to create new tabletop views. The surrounding environment inclu...

Eye tracking is growing in popularity for multiple application areas, yet analysing and exploring the large volume of complex data remains difficult for most users. We present a comprehensive eye tracking visual analytics system to enable the exploration and presentation of eye-tracking data across time and space in an efficient manner. The applica...

Working towards active buildings that fully integrate efficient demand management with renewable energy sources and storage, energy efficiency is an important step, as building inefficiencies cause energy wastage and increase energy-related expenses. Currently, static thermal setpoints are typically used to maintain the inside temperature of a buil...

To mitigate the impact of the COVID-19 pandemic, countries around the globe implemented Non-Pharmaceutical Interventions (NPIs), one of which being Working From Home (WFH). In this paper we present an ethnographic investigation into the adaptations of working spaces and habits due to the adoption of WFH. We interviewed 12 participants from differen...

With the increasing availability of head-mounted displays for virtual reality and augmented reality, we can create immersive maps in which the user is closer to the data. Embodiment is a key concept, allowing the user to act upon virtual objects in an immersive environment. Our work explores the use of embodied interaction for immersive maps. We pr...

Immersive Analytics is a quickly evolving field that unites several areas such as visualisation, immersive environments, and human-computer interaction to support human data analysis with emerging technologies. This research has thrived over the past years with multiple workshops, seminars, and a growing body of publications, spanning several confe...

Collaborative visual analytics leverages social interaction to support data exploration and sensemaking. These processes are typically imagined as formalised, extended activities, between groups of dedicated experts, requiring expertise with sophisticated data analysis tools. However, there are many professional domains that benefit from support fo...

Immersive technologies offer new opportunities to support collaborative visual data analysis by providing each collaborator a personal, high-resolution view of a flexible shared visualisation space through a head mounted display. However, most prior studies of collaborative immersive analytics have focused on how groups interact with surface interf...

In building management, usually static thermal setpoints are used to maintain the inside temperature of a building at a comfortable level irrespective of its occupancy. This strategy can cause a massive amount of energy wastage and therewith increase energy related expenses. This paper explores how to optimise the setpoints used in a particular roo...

Shared displays are well suited to public viewing and collaboration, however they lack personal space to view private information and act without disturbing others. Combining them with Augmented Reality (AR) headsets allows interaction without altering the context on the shared display. We study a set of such interaction techniques in the context o...

We explore the adaptation of 2D small-multiples visualisation on flat screens to 3D immersive spaces. We use a ”shelves” metaphor for layout of small multiples and consider a design space across a number of layout and interaction dimensions. We demonstrate the applicability of a prototype system informed by this design space to data sets from diffe...

We present FIESTA, a prototype system for collaborative immersive analytics (CIA). In contrast to many existing CIA prototypes, FIESTA allows users to collaboratively work together wherever and however they wish---untethered from mandatory physical display devices. Users can freely move around in a shared room-sized environment, author and generate...

In immersive display environments, such as virtual or augmented reality, we can make explicit the connections between data points in visualisations and their context in the world, or in other visualisations. This paper considers the requirements and design space for drawing such links in order to minimise occlusion and clutter. A novel possibility...

Optimising the energy consumption of air conditioning systems using machine learning approaches.

Three-dimensional scatterplots suffer from well-known perception and usability problems. In particular, overplotting and occlusion, mainly due to density and noise, prevent users from properly perceiving the data. Thanks to accurate head and hand tracking, immersive Virtual Reality (VR) setups provide new ways to interact and navigate with 3D scatt...

In multi-display environments (MDEs) that include large shared displays and desktops, users can engage in both close collaboration and parallel or personal work. To transition between the displays can be challenging in complex settings, such as crisis management rooms. To provide workspace awareness and to factilitate these transitions, we design a...

In this thesis, I study the benefits of collaboration in front of Ultra-High ResolutionInteractive Wall Displays (UHRWD). I focus on the specific collaborative context of control rooms.Visits of control rooms and interviews with operators show that different degrees of collaboration arerequired in function of the situation. I believe that a UHRIWD...

Road traffic control centers are of vital importance to modern cities. Interviews with controllers in two such centers identified the need to incorporate the visualization of results from predictive traffic models with real traffic, to help operators choose among different interventions on the network. We explore this idea in a prototype that runs...

Immersion is the subjective impression of being deeply involved in a specific situation, and can be sensory or cognitive. In this position paper, we use a basic model of visual perception to study how ultra-high resolution wall displays can provide visual immersion. With their large size, depending on the position of viewers in front of them, wall...

Wall-displays allow multiple users to simultaneously view and analyze large amounts of information, such as the increasingly complex graphs present in domains like biology or social network analysis. We focus on how pairs explore graphs on a touch enabled wall-display using two techniques, both adapted for collaboration: a basic localized selection...

Dans les grandes villes ou sur les autoroutes, le trafic routier est un système complexe qui peut être très instable. La moindre perturbation peut se transformer en embouteillage qui va ensuite paralyser le réseau. Pour éviter cela, des chercheurs travaillent sur la modélisation et l'optimisation du trafic routier. De plus, le trafic est surveillé...

The International Civil Aviation Organisation (ICAO) identify an Airprox to be a situation in which, in the opinion of a pilot or air traffic services personnel, the distance between aircraft as well as their relative positions and speed have been such that the safety of the aircraft involved may have been compromised. These are relatively rare eve...
