Oct 7th: University of Edinburgh Seminar by Aaron Quigley


Aaron will be giving a seminar in the School of Informatics in the Univeristy of Edinburgh on October 7th 2011 on the topic of:

Challenges in Social Network Visualisation

Information Visualisation is a research area that focuses on the use of graphical techniques to present abstract data in an explicit form. Such static (pictures) or dynamic presentations help people formulate an understanding of data and an internal model of it for reasoning about. Such pictures of data are an external artefact supporting decision making. While sharing many of the same goals of Scientific Visualisation, Human Computer Interaction, User Interface Design and Computer Graphics, Information Visualisation focuses on the visual presentation of data without a physical or geometric form.
As such it relies on research in mathematics, data mining, data structures, algorithms, graph drawing, human-computer interaction, cognitive psychology, semiotics, cartography, interactive graphics, imaging and visual design. In this talk Aaron will present a brief history of social-network analysis and visualisation, introduce analysis and layout algorithms we have developed for visualising such data. Our recent analysis focuses on actor identification through network tuning and our Social Network Assembly Pipeline, SNAP which operates on the premise of “social network inference” where we have studied it experimentally with the analysis of 10,000,000 record sets without explicit relations. Our visulisation has focussed on large scale node-link diagrams, small multiples, dynamic network displays and egocentric layouts.  The talk concludes with a number of challenges and open research questions we face as researchers in using visualisation in an attempt to present dynamic data sources.

Mirco Musolesi, Sensing, Understanding and Modelling People using Mobile Phones


<!–Speaker: Mirco Musolesi,  Computer Science, University of St Andrews
Date/Time: 1-2pm July 26th, 2011
Location: 1.33a Jack Cole, University of St Andrews (directions)–>
Abstract:
Mobile phones are increasingly equipped with sensors, such as accelerometers, GPS receivers, proximity sensors and cameras, that can be used to sense and interpret people behaviour in real-time. Novel user-centered sensing applications can be built by exploiting the availability of such technologies in these devices that are part of our everyday experience. Moreover, data extracted from the sensors can also be used to model people behaviour and movement patterns providing a very rich set of multi-dimensional data, which can be extremely useful for social science, marketing and epidemiological studies.
In this talk I will present some of my recent work in this area including the design and implementation of the CenceMe platform, a system that supports the inference of activities and other presence information of individuals using off-the-shelf sensor-enabled phones and of EmotionSense, a system for supporting social psychology research. Finally, I will discuss the issues related to the design of energy-efficient social sensing systems.

One week until Summer School in St Andrews


Some of the equipment for Summer School

Some of the equipment for Summer School


You can see some of the Arduino and Kinect equipment we have for the summer school here starting on June 26th with an Arduino workshop. The focus of this summer school is to introduce a new generation of researchers to the latest research advances in multimodal systems, in the context of applications, services and technologies for tourists (Digital Tourism). Where mobile and desktop applications can rely on eyes down interaction, the tourist aims to keep their eyes up and focussed on the painting, statue, mountain, ski run, castle, loch or other sight before them. In this school we focus on multimodal input and output interfaces, data fusion techniques and hybrid architectures, vision, speech and conversational interfaces, haptic interaction, mobile, tangible and virtual/augmented multimodal UIs, tools and system infrastructure issues for designing interfaces and their evaluation. Mornings are devoted to seminars from our international speakers followed by guided group work sessions or focussed time for project development. We are proving a dedicated lab with development machines for the duration of the school along with access to a MERL Diamondtouch, a Microsoft Surface (v1.0), a range of mobile devices, arduinos, phidget kits, pico-projectors, Kinects and haptic displays. As we expect participants from a range of backgrounds to attend we will form groups who will, through a guided process, propose a demonstrator they can realise during the summer school which they will demonstrate and showcase on the final day.

Aaron delivers an invited seminar in Heriot-Watt


Aaron is giving a seminar at the Department of Computer Science at Heriot-Watt University (Edinburgh) on Wednesday the 18th of May 2011 at 15:15. This talk will be unlike his colloquium talk in March as it focuses on the particular challenges and research questions when dealing with a dynamic source of data (and hence information).
Title: Dynamic Information Visualisation

SNAP: Social Network Assembly Pipeline

SNAP: Social Network Assembly Pipeline and Visualisation


Societies continued reliance on information and communications technologies has resulted in organizations generating, gathering, and storing “raw data” at a rate growing each year. The ability for even a mid-sized organization to store tens to hundreds of terabytes of data is already within reach.
Massive storage technologies are rapidly outstripping our ability to effectively analyse, explore, and understand such voluminous data. While research in other fields such as data mining, machine learning and knowledge management are also attempting to aid in the analysis of such voluminous data, there is a realisation that the “human-in-the-loop” affords a visual analysis not possible through automation alone. A further challenge now often faced is that the source of the data isn’t a static snapshot of some signal but is a constant or dynamic stream of data.
As such, the area of visual analytics extends the fields of scientific and information visualisation by incorporating techniques from knowledge management, statistical analysis, cognitive science and decision science. This talk will outline how voluminous dynamic data is modelled, managed, mined and hence visually presented for
exploration. Several data and information visualisation algorithms and methods I have developed with colleagues and students over the past number of years will be described and discussed. The talk concluded with a number of challenges and open research questions we face as researchers in using visualisation in an attempt to present dynamic information (from dynamic data sources).

GPC 2011 Doctoral Colloquium


GPC 2011 Oulu

Good luck to Aaron who is travelling to Oulu in Finland next month to co-chair the Doctoral Colloquium at GPC 2011 the Grid and Pervasive Computing conference. He will spend a few days in Oulu and looks forward to attending GPC as well as seeing the work being undertaken in Ubiquitous Oulu. Ubiquitous Oulu is a prototype of a future ubiquitous city which is being built by the multidisciplinary UBI (UrBan Interactions) program, coordinated by the University of Oulu, and the City of Oulu.

The doctoral colloquium itself offers a chance for PhD students to receive high-quality feedback from external reviewers including Aaron and to directly interact with peers, to exchange ideas, discuss concepts, and establish informal cooperation between researchers and research groups.
Grid and Pervasive Computing (or Ubiquitous Computing) covers research issues and challenges in the field of computer science and engineering in areas of grid and pervasive computing. Grid computing connects computer resources from multiple domains for solving computationally complex scientific, technical or business problems in a distributed fashion. Pervasive or Ubiquitous Computing aims at creating computational devices and systems that will blend into environment to support everyday human activities via natural human computer interaction.
