IEEE VAST Challenge Hat Trick!
The VMG group gain success at the annual IEEE VAST Challenge for the third year running, which is indicative of our strength at international level in the field of visual analytics. The VAST Challenge provides synthetic data sets with an embedded ground truth surrounded by obfuscating data, and challenges teams to correctly answer a series of questions on the scenario.
The VAST 2012 challenge was to investigate the cyber situational awareness of a fictitious international bank called the `Bank of Money'. Two datasets were provided for the first challenge, the first contained meta-data that describes the computer network of the bank. This consisted of nearly 1 million individual machines divided over 4,056 geographically dispersed facilities which included datacenters, regional offices and branches. The second dataset contained the output of status updates for all computers on the banks network for two days. The status of each machine is stored every 15 minutes and provides details about deviations from corporate policies and the current activity for each individual machine. When stored as comma-separated-values the main dataset is approximately 8GB.
The Bangor team of Francis Williams, William Faithfull and Jonathan Roberts developed a tool named SitaVis (click on the image above to download a movie of SitaVis in action), that was used to discover the situation of the network of the Bank of Money. The team says "SitaVis offers a visual overview (an overview of the situation) of the network with the ability to drill down into the data using direct interaction techniques". "Network datasets are large and therefore we have developed an interactive framework that enables the dynamic exploration and interactive analysis of the data using aggregation techniques and Microsoft's XNA framework.". The entry was awarded an "Honorable Mention for Good Situational Awareness Snapshot".
For VAST 2011, Bangor's team consisted of Llyr ap Cenydd, Rick Walker, Serban Pop, Helen Miles, Chris Hughes, William Teahan and Jonathan C. Roberts. There were a number of mini-challenges, and the one we tackled was concerned with tracking the spread of an epidemic within a city using Twitter messages. We built a tool to help us understand the underlying narrative of the scenario, and to analyse the data and discovered not just the spread, but also the transmission method and cause of the epidemic.
Our submission was selected for an award - "Outstanding Analysis Using Custom Tools" - and was subsequently presented at a workshop as part of Visweek 2011 in Providence, RI in October. There were 30 entries from around the world with solutions to this mini challenge. Four other entries received awards (from Purdue University, VIS Stuttgart, VSTI/SAS, and MTA-SZTAKI). More details about the 2011 Bangor implementation can be found here:VAST 2010, the team of senior lecturer Jonathan C Roberts and post-docs Serban Pop, Rick Walker and Llyr ap Cenydd tackled a mini-challenge concerned with the spread of a pandemic across several countries. We built a tool to analyse the data provided, using a combination of multiple views and statistics, and were able to use it successfully answer all the mini-challenge questions. The picture below is a snapshot of our analysis - click on the image to download a short movie (divx format) showing our tool in action.
This entry received an award for "Good analytic process and explanation", and was presented at the VAST Challenge 2010 Participant Workshop in Utah in October. The other award winners for this mini challenge were a joint team from Purdue University and University of Houston, a team from University of Konstanz, and a team from commercial company Periscope.

TP.CG.07 Conference comes to Bangor
Over 60 delegates attended the Theory and Practice of Computer Graphics 2007 (TP.CG.07) conference, which was hosted by the School of Computer Science and held at Technium CAST, 13-15 June 2007. This was the 25th consecutive annual conference of the Eurographics UK Chapter. Dr Ik Soo Lim was Programme Chair with Prof David Duce (Oxford Brookes University); and Dr Thomas Varsamidis and Prof.Nigel John were the local organisers. The conference attracted paper submissions from across the world and seven papers involving researchers from the University of Wales, Bangor were accepted. Of particular note for the HPV-MG group was that the Ken Brodlie Prize for Best Paper was awarded to Llyr ap Cenydd for his paper and presentation "The Dynamic Animation of Ambulatory Arthropods".

Wellcome Trust People Award
Ik Soo Lim has been awarded funding for a project: Three-Dimensional Anatomy Colouring. Our objective is to engage school pupils in a learning-by-doing activity as an entertaining and instructive guide to 3D (3-Dimensional) human anatomy. This project aims to provide a paradigm shift in teaching anatomy to school pupils. To avoid the shortfalls in 2D anatomy colouring, this project will develop an activity for the pupils in which they will digitally extract anatomical structures from 3D medical images. Using innovative computer software we constructed, the pupil will "digitally paint" a few points of an anatomic structure and other points of the remaining structures in a volumetric image. The software uses these examples to classify the whole image into two different regions. After a few iterations of this semi-automatic scheme, the anatomic structure of interest will be extracted and viewed by utilising a stereoscopic display. Using the latest 3D printing technology, following each lesson we will construct physical models of the segmented anatomy for the pupils to touch and hold.
Project Funding Success
The EPSRC has agreed funding for a project to develop a Physics-based virtual environment for training in vascular interventional radiological procedures. This will be a collaborative project with Liverpool, Hull, Leeds and Imperial universities. The project will develop, integrate and validate a complete virtual environment for training in vascular interventinal radiology, encompassing needle puncture as well as guidewire and catheter insertion and manipulation.
A second project in this area has also been funded by the Department of Health under the Health Technology Devices Programme. The project will develop and validate a virtual reality simulator for training in interventional radiological visceral needle puncture procedures. The work will be in collaboration with Liverpool, Leeds, Imperial and Hull Universities, and Medic Vision Pty Ltd.

Presentation at MMVR14 2006
Chris Hughes presented his work on "A flexible infrastructure for delivering Augmented Reality enabled Transcranial Magnetic Stimulation" at the 14th Medicine Meets Virtual Reality conference, January 24-27, Long Beach, California. Transcranial Magnetic Stimulation (TMS) is the process in which electrical activity in the brain is influenced by a pulsed magnetic field. Common practice is to align an electromagnetic coil with points of interest identified within the brain, from an MRI scan of the subject. The coil can be tracked using optical sensors, enabling the targeting information to be calculated and displayed on a local workstation. In this paper we explore the hypothesis that using an Augmented Reality (AR) interface for TMS will improve the efficiency of carrying out the procedure. We also aim to provide a flexible infrastructure that if required, can seamlessly deploy processing power from a remote high performance computing resource. (See also the e-Viz project web site).

Prof. Nigel John gave a keynote talk at CyberWorlds 2005
Prof. Nigel John presented a key-note paper on "Cybermedicine - What is possible, and is it useful?" at the 2005 International Conference on CYBERWORLDS, Singapore, Nov 23-25, 2005. Abstract: The medical domain provides excellent opportunities for the application of computer graphics, visualization, and virtual environments, with the potential to help improve healthcare and bring benefits to patients. Possible applications include anatomical educational tools; diagnostic aids; virtual endoscopy; planning aids; guidance aids; skills training; and computer augmented reality. This talk will provide a comprehensive overview of the state-of-the-art in this exciting field, including examples from research projects and commercially available products. The term Cybermedicine will be introduced to categorise those medical applications that can be delivered via the World Wide Web, preferably in the context of a collaborative virtual environment. The issues for effective cybermedicine will be discussed, and we will look ahead to future developments.
