Abstract:
Recent developments and ubiquitous use of global positioning devices have revolutionised movement analysis. Scientists are able to collect increasingly larger movement data sets at increasingly smaller spatial and temporal resolutions. These data consist of trajectories in space and time, represented as time series of measured locations for each moving object. In geoinformatics such data are visualised using various methodologies, e.g. simple 2D spaghetti maps, traditional time-geography space-time cubes (where trajectories are shown as 3D polylines through space and time) and attribute-based linked views. In this talk we present an overview of typical trajectory visualisations and then focus on space-time visual aggregations for one particular application area, movement ecology, which tracks animal movement.

Purposeful Map-Design: What it Means to Be a Cartographer when Everyone is Making Maps

<!–Speaker: David Heyman, Axis Maps
Date/Time: Fri, Feb. 1, 2pm
Location: School III, St Salvator’s Quad, St. Andrews–>
Abstract:
The democratizing technologies of the web have brought the tools and raw-materials required to make a map to a wider audience than ever before. This proliferation of mapping has redefined modern Cartography beyond the general practice of “making maps” to the purposeful design of maps. Purposeful Cartographic design is more than visuals and aesthetics; there is room for the Cartographer’s design decisions at every step between the initial earthly phenomenon and the end map user’s behavior. This talk will cover the modern mapping workflow from collecting and manipulating data, to combining traditional cartographic design with a contemporary UI/UX, to implementing these maps through code across multiple platforms. I will examine how these design decisions are shaped by the purpose of the map and the desire to use maps to clearly and elegantly present the world.
Bio:
David Heyman is the founder and Managing Director of Axis Maps, a global interactive mapping company formed out of the cartography graduate program of the University of Wisconsin. Established in 2006, the goal of Axis Maps has been to bring the tenants and practices of traditional cartography to the medium of the Internet. Since then, they have designed and built maps for the New York Times, Popular Science, Emirates Airlines, Earth Journalism Network, Duke University and many others. They have also released the freely available indiemapper and ColorBrewer to help map-makers all over the world apply cartographic best-practices to their maps. Recently, their series of handmade typographic maps have been a return to their roots of manual cartographic production. David currently lives in Marlborough, Wiltshire.

Abstract:
Interactive exhibits have become highly expected in traditional museums today. The presence of hands-on exhibits in science centres along with our familiarity of high quality media experiences in everyday life has increased our expectations of digital interactive exhibits in museums. Increased accessibility to affordable technology has provided an achievable means to create novel interactive in museums. However, there is a need to question the value and effectiveness of these interactive exhibits in the museum context. Are these exhibits contributing to the desired attributes of a visitors’ experience, social interactions and visitors’ connection with subject matter or hindering these factors? The research focuses specifically on multimodal interactive exhibits and the inappropriate or appropriate combination of modalities applied in interactive exhibits relative to subject matter, context and target audience. The research aims to build an understanding of the relationships between different combinations of modalities used in exhibits with museum visitors experience, engagement with a topic, social engagement and engagement with the exhibit itself. The talk will present two main projects carried out during the first year of the PhD research. The first project presented will describe the design, development and study of a Multimodal painting installation exhibited for 3 months in a children’s cultural centre for children. The second project presented is an on-going study with the Riverside Transport Museum in Glasgow of six existing multimodal installations in the Transport Museum.

Next year Miguel will join the program committee for the 2nd International Symposium on Pervasive Displays 2013 in cooperation with ACM / SIGCHI
“As digital displays become pervasive, they become increasingly relevant in many areas, including advertising, art, sociology, engineering, computer science, interaction design, and entertainment. We invite submissions that report on cutting-edge research in the broad spectrum of pervasive digital displays, from large interactive walls to personal projection, from tablets and mobile phone screens to 3-D displays and tabletops. The symposium on Pervasive Displays welcomes work on all areas pertaining to digital displays”. http://www.pervasivedisplays.org/2013/

Aaron and Per Ola are two of the Associate Chairs for MobileHCI 2013, the 15th International Conference on Human-Computer Interaction with Mobile Devices and Services (MobileHCI 2013) which will be held in Munich, Germany August 27 – 30, 2013.
“MobileHCI is the world’s leading conference in the field of Human Computer Interaction concerned with portable and personal devices and with the services to which they enable access. MobileHCI provides a multidisciplinary forum for academics, hardware and software developers, designers and practitioners to discuss the challenges and potential solutions for effective interaction with and through mobile devices, applications, and services.” http://www.mobilehci2013.org/ Per Ola is also the workshops co-chair for MobileHCI 2013, the call for workshops 2013 is here.

Aaron will be joining the Technical Program Committee of the 2013 ACM International Conference on Pervasive and Ubiquitous Computing (UbiComp 2013).
The UbiComp 2013 Program Chairs are Marc Langheinrich, John Canny, and Jun Rekimoto and they said of UbiComp 2013. That it is the first merged edition of the two most renowned conferences in the field: Pervasive and UbiComp. While it retains the “UbiComp” short-name in recognition of the visionary work of Mark Weiser, its long name (and focus) reflects the dual history of the new event, i.e., it seeks to publish any work that one would previously expect to find at either UbiComp or Pervasive. The conference will take place from September 8-12 in Zurich, Switzerland. Aaron has previously served on a number of Pervasive and UbiComp Technical program committees and looks forward to serving on this first joint conference UbiComp TPC which is now the premier forum for Ubiquitous and Pervasive Computing research.

Next week Professor Quigley is presenting a seminar in the University of Konstanz, Germany as an invited speaker by Professor Harald Reiterer
Abstract:
The computational and contextual edifice around which we will build our ubicomp user interfaces is complex and constantly changing. This context include physiological, environmental and computational state. In this regard, can we model the physiological differences between people and use the models to adapt and personalize designs, user interfaces and artefacts? Can we model, measure and predict the cost of users altering their gaze in single or multi-display environments? If so, can we personalize interfaces using this knowledge. What about when moving and while the distance between user and screen is varying. Can this be considered a new modality and used to personalize the interfaces along with physiological differences and our current gaze. In this talk we seek to answer some of these questions. We define Ubicomp User Interfaces and introduce an Individual Observer Model of human eyesight, which we use to simulate 3600 biologically valid human eyes. We also report on controlled lab and outdoor experiments with real users. This is to measure both gaze and distance from the screen in an attempt to quantify the cost of attention switching along with the use of distance as a modality. In each case, for distance, gaze or expected eyesight we would like to develop models which can allow us to make predictions about how easy or hard it is to see visual information and visual designs, along with altering the designs to suit individual users based on their current context.
