Time Talk
9:00 – 9:10 Opening and Welcome (Tomasz Bednarz)
9:10 – 9:40 Keynote: Augmented and Virtual Reality a Scientific Tool by Professor Bruce Hunter Thomas Ph.D.

The advent of quality virtual environment equipment and software as consumer products has revolutionized Augmented and Virtual Reality. What is interesting are applications outside the training and entertainment fields. Games are the purposed “killer app” for virtual environments. While this has the potential for a large slice of the market, making AR and VR solve real-world problems is the real end game for this field of research. In particular, my research group is interested in the use of AR and VR for the visualization of concepts and data. This talk will explore the use of AR and VR for: Immersive analytics, understating cognitive psychology, understanding criminal cases, and comprehending large-scale designs.

The will provide a short introduction to the concepts of AR and VR. The talk will go on to describe some current projects we are investigating. The key elements of AR and VR as an effective scientific tool will be explored. The talk will finish with some remarks on future research directions.

9:40 – 10:00 Multiplicitous Media : the pleasures and perils of creating large-scale multi-device distributed sound and light artworks by Oliver Bown (UNSW Art & Design)

Small, low-cost and low-power computational devices enable a new approach to digital media where hundreds or thousands of individual points of light or sound act in unison through networked distributed computation. In this talk I discuss work with the media arts group Squidsoup who are in the process of evolving their spatial interactive lighting systems toward an internet-of-things infrastructure, developing custom networked media systems that can be rapidly deployed and reconfigured for experience design. I discuss some of the pleasures and perils of creating work for this kind of technology and consider how it will transform the design of architectural and urban experiences.

10:00 – 10:20 Digital Placemaking is the Future of Visual Creativity by Emile Rademeyer (VANDAL)

Art, science, design and engineering can change human behaviour. Creative use of digital technology can do the same and much more. In this innovative session Emile Rademeyer explores why Digital Placemaking is the future of visual creativity. Digital Placemaking allows us to connect with people, increase engagement and enhance human emotion like never before. It alters human behaviour and will shape the future of civilisation as never seen before.

10:20 – 10:40 Towards Visualisation for Stellargraph: Machine Learning on Graphs by Xavier Ho (CSIRO’s Data61), Anna Leontjeva (CSIRO’s Data61)

In recent years, there has been a surge in graph data publications [1, 2]. In government and industry where many assets are highly interrelated, decision makers can benefit greatly from utilising graph technologies. However, as graph data continue to increase in complexity, decisive insights also become more obscure and difficult to discover. A current challenge is to identify new leads for graph exploration and analysis. To address the issue of complex insight discovery, Stellargraph seeks to bring machine learning to graph data. Stellargraph has three technology objectives. First, it provides an open-source machine learning library 1 designed to apply powerful machine learning techniques on graphs. Second, it offers a scalable software and data platform, currently under active development, to be integrated with and optimised for the machine learning library. Third, it aims to strengthen strategic decision making through interactive graph visualisations, which is the focus of this talk. In this talk, we will present a brief overview of graph visualisation principles [3, 4], and establish useful techniques available in practice. We will highlight some of the current challenges in using network visualisation for investigative analytics and discuss some of our ongoing research. The talk will conclude with a live demonstration of the work-in-progress Stellargraph visualisation component.

10:40 – 11:10 Break
11:10 – 11:30 A Look Inside The Supercomputer by Sam Moskwa

Dive inside the workings of a supercomputer including how to visualise the mind-boggling number juggling they routinely perform, some unexpected applications, and the engineering behind these metal monsters.

11:30 – 11:50 Molding is the new balck by Nico Pietroni (UTS)

While 3D printing technologies are becoming faster and more precise, classical manufacturing techniques remain the  first choice for most industrial application scenarios. Industrial production is still largely dominated by casting techniques: casting scales well with the number of copies, supports a wide spectrum of materials, and ensures high geometric accuracy.

In this talk I will show recent advancement on geometry processing and shape analysis for the automatic design and fabrication of 3D printed molds. I will show the technical details and the effectiveness of new technologies that use 3D printing to automatise industrial production processes.

11:50 – 12:10 Experience and live energy configurations by Douglas Kahn (UNSW)

“Cell Melodies” (November 7-9, 2016) was an art and science experiment created by a team lead by Carlo Ventura, Professor of Molecular Biology and a stem cell scientist at University of Bologna. It sought to demonstrate responsiveness of human stem cells to live performances by the American percussionist and pioneer of free jazz, Milford Graves, and the Italian actor, Alessandro Bergonzoni. This paper examines “Cell Melodies” with respect to the music, health practices and cosmograms of Graves, and the discourses on vibration and energy in artistic practice and cultural theory since the early twentieth century, and proposes that redressing the rift between experience and representation in visualization can be approached through a pluralistic theory of energies where concepts, cultural manifestations, and material realities are historically specified and configured among “fields” of energy.

12.10 – 12.30 Living dangerously with live technology by John Doolan (Virtual Immersive)

John will explore augmentation using real time graphics to enhance user engagement.  This talk will involve live and potentially disastrous technology.

1:30 – 1:50 Transforming how biomedical data is seen by Sean O’Donoghue (BABS, UNSW)

This talk will showcase data visualizations being used to explore and understand biomedical datasets, that explore the limits of current knowledge. This includes: (1) a systematic map of the protein ‘structural universe’; (2) a survey of the unknown ‘dark proteome’ (covering about half of the proteins in humans); and (3) an exploration of the three-dimensional organization of our genome (currently almost completely unknown). Finally, the talk will show how visualization is also being used to help explain scientific breakthroughs, engaging the community in the exciting and important missions of biomedical research.

1:50 – 2:10 Reorganisation as ‘visualisation’ for understanding and exploring audio signals by Sam Ferguson

Sound is commonly analysed subjectively by listening to it. However, when we want to analyse a sound objectively, we often attempt to understand sound by reducing the complexity of a sound signal to single temporally-changing numerical values, which can then be visualised in various ways. This talk instead describes and demonstrates a general scheme for building statistical representations of sound that reorganise the original audio data so that the statistical characteristics of the sound can be perceived directly.

2:10 – 2:30 XR Learning Objects – A web based solution by Carlos Dominguez

Extended reality (XR) is the term used to describe all the immersive realities: virtual reality, augmented reality, mixed reality and diminished reality. A web based solution incorporates those realities into the web using different frameworks such as a-frame, ar.js, html5, argon.js and other javascript libraries and APIs. Those objects then are incorporated into the academic curriculum resulting in XR Learning Objects. Our goal is to create XR Learning Objects as supporting learning tools. We connect front end and back end using an LTI tool and represent the data via an Immersive Analytics Dashboard. An XR Learning Object is highly engaging, visual, immersive and incorporates the curriculum learning outcomes.

3:00 – 3:20 Faces are the Emotional Dimension of Computing: Giving the world a better face by Mike Seymour

The way we deal with our machines is very different from the way we interact with each other. Computer metaphors hail back to the notion of a desktop, with file, folders and trash bins.

What if your computer could interact with your emotionally, with a smile? How could we do this and what are the ethical implications if we do? Based on international research this talk explores digital humans both technically and conceptually.

3:20 – 3:40 Creative interaction with data by Jennifer Seevinck (QUT)

What does it mean to ‘make’ with data? Jen discusses recent projects creating interactive art systems that respond to audiences and visualise data. Three of her interactive artworks working with near real time wind, water data and audience movement and gesture, are presented. These art systems have informed questions around hybrid place, data as site and data as a material that guides creative practice.

3:40 – 4:00 Frayed Nerves & the Cognitive casualties of war by Tia Cummins (Florey Institute of Neuroscience & Mental Health )

Traumatic Brain Injury (TBI) and Post-Traumatic Stress Disorder (PTSD) are an all too common consequence of military service. Known as the signature wound of modern warfare, over 350,000 US military service personnel have suffered a TBI since 2000. PTSD is estimated to affect up to 20% of Iraq veterans. Epidemiological research indicates that veterans with TBI or PTSD are 2-4 times more likely to develop dementia than controls; however, mechanisms contributing to this relationship are poorly understood. In our landmark study, we set out to investigate if Vietnam war veterans with a TBI, and/or PTSD showed evidence of Alzheimer’s disease (AD) by using a range of measures including state of the art neuroimaging techniques, PET and MRI.

In this talk I will discuss the findings of this study, and demonstrate the important role visualisation of neuroimaging plays in the world of medicine.

4:00 – 4:20 Immersive Analytics of Honey Bee Data by Huyen Nguyen (UNSW)

Bees are dying – in recent years an unprecedented decline in honey bee colonies has been seen around the globe. The causes are still largely unknown. At CSIRO, the Global Initiative for Honey bee Health (GIHH) is an international collaboration of researchers, beekeepers, farmers, and industry set up to research the threats to bee health in order to better understand colony collapse and find solutions that will allow for sustainable crop pollination and food security. Integral to the research effort is RFID tags that are manually fitted to bees. The abundance of data being collected by the thousands of bee-attached sensors as well as additional environmental sensors poses several challenges regarding the interpretation and comprehension of the data, both computationally as well as from a user perspective. In this talk, I will discuss visual analytics techniques that we have been investigating to facilitate an effective path from data to insight. I will particularly focus on interactive and immersive user interfaces that allow for a range of end users to effectively explore the complex sensor data.

4:20 – 4:40 Visualisation as a means of understanding and communicating measurement uncertainty by Dr Victoria Coleman (Australia’s National Measurement Institute)

Currently, complex, multidimensional measurement data cannot be easily presented together with the corresponding measurement uncertainties data in a comprehensible and intuitive form. This generic problem is prevalent in research, development and science commercialisation, and is particularly critical for metrology due to the need to evaluate measurement results together with their uncertainties – a task that is all the more challenging given a perpetually increasing volume of data.

Nanometrology – the science of measurement at the nanoscale – is an example of an emerging area of metrology in which improvements in visualisation could lead to a greater understanding of the relationship between measurement results and associated uncertainty data. Improvements in this field could potentially lead to improvements in instrument or measurement design, as well as an increase in the uptake of the information and its perceived value by stakeholders.

4.40 – 5.00 Online visualization of hexahedral meshes by Marco Tarini

Hexahedral meshes are discretized volumetric 3D models commonly employed in applications such as Finite Elements Methods or other physical simulations. Their construction is recognized to be a challenging field of research in the context of geometry processing and FEM.  This talk addresses the task of their real-time visualization, exploration and assessment.  For this purpose, we present a tool-set targeted at practitioners and scholars, which can be used to readily assess quality of the meshing and consequently the usability of the model for simulation.  This can be used by researchers involved in the design of hexa-mesh generation algorithms to perform a detailed visual analysis of the obtained results, and compare them to previous and concurrent solutions. The system is offered as a easily accessible online suite, which doubles as a portal to a growing benchmark consisting of publicly available datasets produced with recent techniques.
