This paper is based upon a case study. Gillard Associates completed the refurbishment of the first of three 1960’s student accommodation blocks at Atlantic College, Wales in late summer 2008. The refurbishment was predicted to possibly achieve Code for Sustainable Homes level4, through the use of a combination of Archicad BIM and Ecotect Building Performance simulation software.The Cardiff School of Art and Design (CSAD) have now acquired re-deployable instrumentation with the intent of monitoring the refurbished accommodation through a complete cycle of seasons, in comparison with one of the existing blocks, and with the predicted results from the simulation process. CSAD intend to build upon the model of the ‘Live Studio’ learning case study that incorporates real time data from the building management system sensors and weather station. We argue that there is a lack of useful seasonal case study data for practitioners to calibrate their simulations, and for learning by students.

The identification and case management of those at risk high for Hereditary Breast and Ovarian Cancer (HBOC) involves the synthesis of data from self reported patient family history, quantitative risk model analysis, and current clinical standards of care. This paper describes an integrated interactive visualization and analysis approach for the presentation of these data that is suitable for large scale risk stratification. We describe this display of HBOC risk information integrated with a clinical decision support that is also potentially useful across other cancer syndromes.

Most existing visualization tools utilize only the visual channel to represent information. Several studies have demonstrated that sonification,the use of sound as an alternative or additional channel for data representation, can help increase the dimensionality of the visual representation and aid in the interpretation of information. We introduce a new sonification module for a visual data exploration system, the Super Spider. It extends a previously developed interactive visualization tool cite{minghim05spider} to support data exploration using sound. We also introduce a new data sonification technique and system, 2D Sonar. We have integrated it into Super Spider. Finally, we present user studies conducted to evaluate and validate the efficacy of visual and auditory mappings devised for these tools, and their results.

Elinor is a game based tool for rehabilitation of stroke patients to be used in their home environment. The application is the result of a creative and exploratory development project in which researchers in the serious games area and experts in stroke rehabilitation collaborated in order to develop a motivating, easy to use and relatively inexpensive tool for relearning functions lost due to a stroke. Elinor can be viewed as an integrated system for stroke rehabilitation in that it is both a system, controlled by movements, for training of its primary user group and a system for monitoring the training by medical expertise. In this paper, we will describe the Elinor application itself, the development process and the initial evaluation of it in order to identify implications for serious games.

A repository containing perceived quality data for polygonal meshes, obtained through observer studies, is presented. It includes information regarding the experimental methodology, protocol and models used, with the purpose of allowing researchers to use it, e.g., for a faster preliminary assessment of their perceived quality metrics without the overhead of designing and performing an observer study.

Architects conceive buildings as three dimensional forms, often developing their designs using 3D CAD [Computer Aided Design] or visualization software. Yet their designs are usually presented to each other and to their clients as two dimensional artifacts: such as images or movies created from their CAD models. In computing, interactive three dimensional worlds are ubiquitous, in particular in the fields of Gaming and Social Networking involving MUVEs [Multi-User Virtual Environments] such as Second Life.This work explores the options available to students, whose work is primarily designed in three dimensions, to present their work digitally through 3D ePortfolios. It makes recommendations from a range of possible solutions as to the most suitable for the implementation of online ePortfolios which contain interactive models of building designs.

The arrangement of atoms at the surface of a solid accounts for many of its properties: Hardness, chemical activity, corrosion, etc. are dictated by the precise surface structure. Hence, finding it, has a broad range of technical and industrial applications. The ability to solve this problem opens the possibility of designing by computer materials with properties tailored to specific applications. Since the search space grows exponentially with the number of atoms, its solution cannot be achieved for arbitrarily large structures. Presently, a trial and error procedure is used: an expert proposes an structure as a candidate solution and tries a local optimization procedure on it. The solution relaxes to the local minimum in the attractor basin corresponding to the initial point, that might be the one corresponding to the global minimum or not. This procedure is very time consuming and, for reasonably sized surfaces, can take many iterations and much effort from the expert. Here we report on a visualization environment designed to steer this process in an attempt to solve bigger structures and reduce the time needed. The idea is to use an immersive environment to interact with the computation. It has immediate feedback to assess the quality of the proposed structure in order to let the expert explore the space of candidate solutions. The visualization environment is also able to communicate with the de facto local solver used for this problem. The user is then able to send trial structures to the local minimizer and track its progress as they approach the minimum. This allows for simultaneous testing of candidate structures. The system has also proved very useful as an educational tool for the field.

Facial expressions can be used to communicate emotional states through the use of universal signifiers within key regions of the face. Psychology research has identified what these signifiers are and how different combinations and variations can be interpreted. Research into expressions has informed animation practice, but as yet very little is known about the movement within and between emotional expressions. A better understanding of sequence, timing, and duration could better inform the production of believable animation. This paper introduces the idea of expression choreography, and how tests of observer perception might enhance our understanding of moving emotional expressions.

Geometric constraint solving has applications in many different fields, such as Computer-Aided Design, molecular modelling, tolerance analysis, and geometric theorem proving. Geometric modelling by constraints enables users to describe shapes by relationships called constraints between geometric elements. The aim is to derive automatically these geometric elements and provide thus effort and time saving. Moreover, users can easily modify existing designs. Many resolution methods have been proposed for solving systems of geometric constraints. We classify these methods in three broad categories: algebraic, rule-oriented and graph-constructive solvers.
