Visualization is coming of age. With visual depictions being seamlessly integrated into documents, and data visualization techniques being used to understand increasingly large and complex datasets, the term "visualization"' is becoming used in everyday conversations. But we are on a cusp; visualization researchers need to develop and adapt to today's new(More)
Sketching designs has been shown to be a useful way of planning and considering alternative solutions. The use of lo-fidelity prototyping, especially paper-based sketching, can save time, money and converge to better solutions more quickly. However, this design process is often viewed to be too informal. Consequently users do not know how to manage their(More)
—As international businesses adopt social media and virtual worlds as mediums for conducting international business, so there is an increasing need for interpreters who can bridge the language barriers, and work within these new spheres. The recent rise in migration (within the EU) has also increased the need for professional interpreters in business,(More)
An important aspect of designing and implementing Augmented Reality (AR) applications and services , often disregarded for the sake of simplicity and speed, is the evaluation of such systems, particularly from non-expert users, in real operating conditions. We are strong advocates of the fact that in order to develop successful and highly im-mersive AR(More)
One of the goals of network administrators is to identify and block sources of attacks from a network steam. Various tools have been developed to help the administrator identify the IP or subnet to be blocked, however these tend to be non-visual. Having a good perception of the wider network can aid the administrator identify their origin, but while network(More)
Haptic devices are becoming more widely used as hardware becomes available and the cost of both low and high fidelity haptic devices decreases. One of the application areas of haptics is Haptic Data Visualization (HDV). HDV provides functionality by which users can feel and touch data. Blind and partially sighted users can benefit from HDV, as it helps them(More)
This paper describes a mobile augmented reality system, based around a wearable computer, that can be used to provide in situ tours around archaeological sites. Ergonomic considerations , intended to make the system usable by the general public , are described. The accuracy of the system is assessed, as this is critical for in situ reconstructions.
Control of a powered wheelchair is often not intuitive, making training of new users a challenging and sometimes hazardous task. Collisions, due to a lack of experience can result in injury for the user and other individuals. By conducting training activities in virtual reality (VR), we can potentially improve driving skills whilst avoiding the risks(More)

Relevance to symposium. We have developed a visual analytic interface that visualizes microblog data, and specific views can be refined such to create a visual storyboard of multivocal trends. Our motivation is to enable an explorative interface for crisis management. Symposium topics (listed in CFP): information trails, analytical reasoning.
