Growing evidence in the scientific literature and in organizations shows the positive impact of employing conceptual visual representation for individual reasoning, communicating and facilitating meetings in organizations. 116 managers responded a questionnaire on the usefulness of 12 common business visualizations for typical knowledge tasks in organizations. The resulting ranking provides an overview of the comparative suitability of visualizations for generating ideas, sharing knowledge, evaluating options and planning. The findings can be used by organizations for evaluating visual templates as a support for specific knowledge tasks. Theoretical implications include the relationship between the structure level of knowledge visualization forms and convergent/divergent task type. Further implications for theory and practice are discussed.

Cardiac angiography using multiple detector row computerized tomography (MDCT) scanners provides 3D data concerning the heart and, in particular, the left ventricle (LV), for different cardiac phases along one cardiac cycle. Exploring this data for LV function analysis is not an easy task, given the amount of data and time involved in segmenting (or revising results provided by automatic segmentation methods) up to 12 cardiac phases. CardioAnalyser, a tool for 4D LV segmentation from MDCT data which provides a protocol to help perform LV segmentation of all cardiac phases available is presented. It uses an automatic segmentation algorithm along with a procedure which guides the user through the process. Its main goal is to reuse as much information as possible from one cardiac phase to the next in order to reduce segmentation time and the amount of user interaction.

Accessing personal and online music libraries with thousands of songs has become an everyday activity. Instead of textual lists, the libraries can also be accessed using graphical visualizations such as adaptive avatars. To develop the idea further, we designed 17 stereotypical avatars representing different musical genres. To study how well the avatars were recognized, an online questionnaire with 71 participants was arranged. This paper discusses the design of the avatars in more detail, explains which musical genres were selected for the study and why, and presents the results of the questionnaire.

This paper describes the application of Medieval and Renaissance color theory to the computer graphic rendering of molecular models. In particular, Alberti’s and Cennini’s color theories were employed to render shaded geometric primitives such as cylinders and spheres that are the components of traditional ball-and-stick and space filling molecular models. These results were compared with standard rendering based on the OpenGL API or through ray tracing. It is found that by implementing Alberti’s and Cennini’s color theories as color maps within a simple chemical illustration program it is possible to create molecular imagery comparable to contemporary computer graphics schemes.

Communication during the design process has a substantial role because; it exchanges messages and conveys ideas to people with different skills and interests. Also, the development of high quality 3D modelling, photo rendering and VR software has shifted the way we communicate architecture, from a conventional one to a digital format and so, provided us with another way for the communication of information, the visualisation of processes and the creative expression of ideas. This paper investigates the impact that Immersive Virtual Reality technology can have on visualisation of a design review scenario in construction, which was developed during the course of the European CoSpaces project and the potential of such technologies to alter the way enterprises work.

One of the most useful techniques to help visual data analysis systems is interactive filtering (brushing). However, visualization techniques often suffer from overlap of graphical items and multiple attributes complexity, making visual selection inefficient. In these situations, the benefits of data visualization are not fully observable because the graphical items do not pop up as comprehensive patterns. In this work we propose the use of content-based data retrieval technology combined with visual analytics. The idea is to use the similarity query functionalities provided by metric space systems in order to select regions of the data domain according to user-guidance and interests. After that, the data found in such regions feed multiple visualization workspaces so that the user can inspect the correspondent datasets. Our experiments showed that the methodology can break the visual analysis process into smaller problems (views) and that the views hold the expectations of the analyst according to his/her similarity query selection, improving data perception and analytical possibilities. Our contribution introduces a principle that can be used in all sorts of visualization techniques and systems, this principle can be extended with different kinds of integration visualization-metric-space, and with different metrics, expanding the possibilities of visual data analysis in aspects such as semantics and scalability.

Conventionally, a grid generator requires either an explicit or implicit description about the boundary vertices, boundary lines and boundary faces to define the geometry. In 2006, the author has developed the Interactive Web based Grid Geometry Construction process [1] to create and generate 2D ubiquitous platform independent, highly scalable, paintbrush, pixel and vector free geometry art. In 2008, she has established a new paradigm -- basically, a fundamental medium for visualization, development, creation and delivery tool for generating grid geometry art and beyond. With exceptions, the result is instantly Web-enabled. She demonstrates the results of the deployment of this image editor free tool by presenting an array of instant conceptualization and artistic realization of an “image” as an arrangement of an uniform m x n grid of colored cells formed within a set of finite orthogonal grids. Beyond which, this paper presents a wide-ranging display of non-orthogonal and soft-edged image free2)2) images.

This paper reviews the state-of-the art of modelling, simulation and visualisation and reviews the recent development of modelling, simulation and visualisation software for Nondestructive Evaluation (NDE). Simulation and visualisation can assist in the design and development of electromagnetic sensing and imaging techniques and systems for nondestructive testing, feature extraction and inverse problems for quantitative nondestructive evaluation. After reviewing the state-of-the art of electromagnetic modelling and simulation, case studies from electromagnetic NDE research and development for eddy current distribution and thermography are discussed.

This paper presents a system for visualizing the information contained in the text of a web page. The goal of the visualization is to help the users better and faster understand the text on a web page and/or find related content on the internet. These visualizations are possible due to the use of text mining, natural language processing and semantic web technologies. Our system tries to make these technologies instantly accessible to a wide variety of users reading a wide variety of web pages. This high coverage of both users and content can be achieved because the system is implemented as an extension to Firefox, one of the most popular browsers, and because the visualizations are computed on the fly for any page the user happens to be reading at a given moment.

Information spaces such the WWW are the most challenging type of space that many people navigate during everyday life. Unlike the real world, there are no effective maps of information spaces, so people are forced to rely on search engines which are only suited to some types of retrieval task. This paper describes a new method for creating maps of information spaces, called INSPIRE. The INSPIRE engine is a tree drawing algorithm that uses a city metaphor, comprised of streets and buildings, and generates maps entirely automatically from webcrawl data. A technical evaluation was carried out using data from 112 universities, which had up to 485, 775 pages on their websites. Although they take longer to compute than radial layouts (e.g., the Bubble Tree), INSPIRE maps are much more compact. INSPIRE maps also have desirable aesthetic properties of being orthogonal, preserving symmetry between identical subtrees and being planar.
