In information systems the data representation covers a great importance. In fact the visualization of information is the last point of contact between the user and the information system. This is the space where the communication takes place. In real-time monitoring systems, this passage covers a great importance, especially for reasons related to the time and the transparency of relevant information. These factors are fundamental to vessel monitoring systems. This is the beginning where we start to define a guidelines manual, act to help specialists of information visualization in the vessel monitoring field, and in the GIS field more in general.

Researches in humanities and social sciences indicate that people using more visual information would be more creative and benefit from the power of the human mind to a higher degree. Therefore information should not only be recorded as static text. It is rather conceivable to construct new visual languages that are not based on letters but on icons. We developed a set of medical symbols that can be used in visual representations of medical records and that may also be used to build complex medical statements. Each of the basic symbols is available in 4 abstraction levels, which can be combined in a ‘visual sentence’. Complex visual representations are recognized more easily than simplified versions, while on the other hand the simple version can be perceived and memorized in a faster way than complex signs. To prove this hypothesis and to evaluate the perception of the symbols in a medical context we created a web-based evaluation tool covering two perception tests. With the help of the symbol library we developed a visual language for patient records and an interactive browser.

Web services provide remote access to distributed resources and processes through uniform interfaces. However, the latency associated with data transmission has meant that they are generally applied to non-interactive data processing. Interactive applications, in which many more user interactions and data transmissions are involved, are difficult to adapt to web service based frameworks, particularly if the interactive investigation involves large datasets. In medical imaging and visualisation, user interactions are generally a prerequisite for the detailed study and manipulation of data. As a result of major scientific initiatives, such as the Virtual Physiological Human, in which large data repositories are being set up at a variety of sites, it is becoming increasingly common for the data being investigated to be stored on a remote server. Consequently, it is now highly desirable to develop a means by which web service based interactive visualisation can be applied to distributed medical data access and clinical collaboration. This paper presents a functional-level plug-in based architecture for interactive data visualisation via web services which is being implemented within the EC-funded ContraCancrum project.

Buildings account for significant carbon dioxide emissions, both in construction and operation. Governments around the world are setting targets and legislating to reduce the carbon emissions related to the built environment. Challenges presented by increasingly rigorous standards for construction projects will mean a paradigm shift in how new buildings are designed and managed. This will lead to the need for computational modelling and visualization of buildings and their energy performance throughout the life-cycle of the building. This paper briefly outline how the UK government is planning to reduce carbon emissions for new buildings. It discusses the challenges faced by the architectural, construction and building management professions in adjusting to the proposed requirements for low or zero carbon buildings. It then outlines how software tools, including the use of visualization tools, could develop to support the designer, contractor and user.

Individuals who have upper limb movement problems include people with cerebral palsy (CP) and stroke victims. Both these conditions lead to difficulties in daily activities such as reaching, grasping etc. Virtual reality (VR), which could provide a repetitive multimodal task-oriented rehabilitation environment for patients to undertake self-training in safety, is considered to be a suitable tool for medical health rehabilitation. Using electromyography (EMG) biofeedback in rehabilitation could provide patients with opportunities to improve the ability by assessing their muscle activity response and learning self-control of movement during specific training tasks. This paper presents a study on developing EMG as an important interactive tool in a VR based system for hand rotation and grasping motion rehabilitation. The input interface includes an EMG system and a real-time magnetic motion tracking system, and the output interface is a PC monitor. The developed EMG biofeedback based VR system enables the user to interact with virtual objects in real-time with multiform feedback. Ten healthy subjects participated in the preliminary task evaluation test, and the results suggest that the specified skills have improved during training. The beneficial effects of the developed system indicate the potential values for further clinical application.

This paper is primarily focused on the increased IT complexity problem and the identification of security threats in networked systems. Modern networking systems, applications and services are found to be more complex in terms of integration and distribution, therefore, harder to be managed and protected. CIOs have to put their effort on threat's identification, risk management and security evaluation processes. Objective decision making requires measuring, identifying and evaluating all enterprise events, either positive (opportunities) or negative (risks) and keeping them in perspective with the business objectives. Our approach is based on a visualisation technique that helps in decision making process, focusing on the threat identification using attack scenarios. For constructing attack scenarios we use the notion of attack graphs, as well as layered security approach. The proposed onion skin model combines attack graphs and security layers to illustrate possible threats and shortest paths to the attacker's goal. By providing few examples we justify the advantage of the threat identification technique in decision making process.

Photo-sharing websites such as Flickr and Panoramio contain millions of geotagged images contributed by people from all over the world. Characteristics of these data pose new challenges in the domain of spatio-temporal analysis. In this paper, we define several different tasks related to analysis of attractive places, points of interest and comparison of behavioral patterns of different user communities on geotagged photo data. We perform analysis and comparison of temporal events, rankings of sightseeing places in a city, and study mobility of people using geotagged photos. We take a systematic approach to accomplish these tasks by applying scalable computational techniques, using statistical and data mining algorithms, combined with interactive geo-visualization. We provide exploratory visual analysis environment, which allows the analyst to detect spatial and temporal patterns and extract additional knowledge from large geotagged photo collections. We demonstrate our approach by applying the methods to several regions in the world.

For several ontology applications, a combination of classes with their instances, their properties on the class level and on the instance level are from interest. However, the focus of most visualization approaches is on the hierarchical and non-hierarchical relationships on the class level. This paper presents an approach to visualizing datatype properties and object properties on the instance level. For this purpose, three different layouts were developed for the ontology visualization tool Knoocks. Furthermore, the paper discusses results of an evaluation that was motivated to identify which one of these layout versions was preferred by the users. The evaluation should also reveal if the concept of the representation of the properties was understandable for them.

Intravital microscopy permits observation of live events in intact tissues to study a variety of issues, including quantifying cell-vessel wall interactions. The analysis of the parameters is labor-intensive, subjective and limited to broad categories of blood cell-vessel wall interactions. We are developing an algorithmic approach that aids in analysis, automatically and objectively detects and tracks platelets, and expands information derived from such videos. We integrate computer vision and break the identification, tracking and visualization into steps. We enable simple and computationally efficient means of eliminating movement within a video based on positively shifting of an identified feature and visualize platelet paths.
