There are two current approaches to the realisation of interactive building 'skins': in architecture so called intelligent facades are being designed with an environmental science agenda; while in a parallel line of inquiry, artists are experimenting with media facades. It is proposed here that there is common ground between reactive environmental facades and data driven screens, in that both involve...
Before architects can begin to make changes in the actual physical environment they must create visual representations of design scheme proposals. Thus, in architecture, information visualisation in graphic form is crucial for discussions and for design review process of architectural design. Within the context of design research and studies there has been a growing interest in recent years in the...
This paper proposes a conceptual model for which one might begin to assess aesthetic effect within the user experience of information visualization. Through first defining, then illustrating new dimensions of aesthetic that exist within the context of information visualization, this paper goes on to suggest that a user centered evaluation method not solely centered around task efficiency metrics is...
The purpose of this article is to view the interplay between technology, concept of value and the role of aesthetics in the Internet-based business through the lens of information design and knowledge and information visualization. We endeavor to show the "big picture", the patterns in structuring and visualizing information around one chosen theme. Showing how to put polyscopic modeling...
A number of research teams are working to organize personalized access to the modern repositories of educational resources. The goal of personalized access is to help students locate resources that match their individual goals, interests, and current knowledge. The project presented in this paper is focused on the least explored way of personalized access - adaptive visualization. Here, we present...
This paper reviews current approaches to design visualization in the built environment and establishes a gap in theory and practice. While it has been acknowledged for some time that the temporal component is an important aspect of visualisation there has been minimal attempts to integrate this approach into design practice. We articulate an approach to visualization which we term 'temporal context'...
This paper describes the search for a balance between aesthetics, usability and corporate identity in product development. This case study shows that usability has been integrated in the process for some time now. Aesthetics and corporate identity is relatively new and not yet incorporated at the same level. Over the past three years we developed a new software style called Ocean. For the first time,...
In the context of urban redesign and public participation, this research project is investigating whether active exploration of a desktop virtual model of an urban environment leads to better understanding and perception than passive observation of a walkthrough of that same model. The results from the experimental study will potentially have implications for how architects and planners present their...
Spatial organisation of information objects on a two or three dimensional plane or space has the advantage of revealing the connections between objects easily by spatial proximity. A user may easily understand, remember and, given an adequate user interface, change the positions and the visual relationships between information objects. If a group of users has access to the same information plane or...
To be most useful, evaluation requires detailed observation and effective analysis of a full spectrum of system use. We have developed an approach and architecture for in-depth data collection and analysis of all use of a visualization system. User interface components in a large visualization and analysis platform automatically record user actions, and can restore previous system states on demand...
The visualization of graphs has proven to be very useful for exploring structures in different application domains. However, in certain fields of computer science, graph visualization is understood and focused quite differently. While "graph drawing" focuses on optimized layouts for node-link-representations of networks, "information visualization" prefers to work on hierarchies...
In today's applications data is produced at unprecedented rates. While the capacity to collect and store new data grows rapidly, the ability to analyze these data volumes increases at much lower pace. This gap leads to new challenges in the analysis process, since analysts, decision makers, engineers, or emergency response teams depend on information "concealed" in the data. The emerging...
This paper describes an action research project based on the process of designing the visualisation of heart and breath rate data for the interactive artwork Cardiomorphologies. The project aimed to realise the affective goals of the artist as closely as possible by studying the audience experience of the visualisations and incorporating the findings into an iterative design process. The qualities...
Textual annotations are important elements in all but the simplest visual interfaces. In order to integrate textual annotations smoothly into the dynamic graphical content of interactive information systems, fast yet high-quality label layout algorithms are required. With the ongoing pervasion of mobile applications these requirements are shifted from workstations to comparatively low-performance...
Many algorithms have been designed to visualize binary trees efficiently with respect to a quality measure. While each algorithm is suitable for drawing particular categories of binary trees, an effort to compile these algorithms to maximize the quality of drawings has not been realized. Our first step is to create a system that determines the type of a binary tree and then selects an algorithm to...
One mission of medical informatics is to provide physicians, nurses, and other health care providers with the technology and tools for interpreting large and diverse data sets, so that appropriate critical care decisions can be facilitated. Ideally, medical data visualization provides the means to transform data into information and contextual knowledge suitable for interpretation and decision-making...
In this paper, we present I-PACK, a deterministic layout algorithm for embedding a data set X in 2D provided that distances (deltauv )u,visinX, between data items are given or can be computed. The layout reflects well similarities and dissimilarities between items and it is computed in quasi-linear time. Experimental comparisons with other multidimensional scaling algorithms show that: i) our algorithm...
Although information visualization claims to provide the means to induce mental models of any kind of data, the visualization of semantic information is still an open field of research. Existing approaches either concentrate on the visualization of documents without additional metadata or produce unintuitive expert graphics. This paper seeks to fill this gap by presenting a semantic information visualization...
This paper describes the design and implementation of a real time animation framework in which animated virtual human is capable of performing multimodal interactions with human user. The animation system consists of several functional components, namely perception, behaviours generation, and motion generation. The virtual human agent in the system has a complex underlying geometry structure with...
Two evaluations of a prototype designed to help expert users visualize key census statistics are conducted. The results yielded are compared in terms of usability issues, task completion (interaction) and ideation facilitated. Ways in which this information may be affected by the use of different data collection techniques, participants and tasks are considered. We report differences in the results...
