Nowadays professional journalists create and edit broadcasting materials inside newsrooms that are characterized by an intense and multivariate flux of information. Within these settings, the journalists have difficulties keeping up with the evolving geopolitical picture of events developing in the world and how it relates to the topics of their interest. In this paper we present AmbientNEWS, an ambient display that visualizes dynamic news content and informs professional journalists on the global picture of events. We argue that the conceptualization and design of its information aesthetics criteria can be grounded in user requirements, and subsequently engaged to augment the awareness of professionals in an environment that is highly crowded with information. We also discuss the evaluation process of ambient information visualization with a focus on aesthetic design aspects. We conclude by summarizing our findings and discuss future work.

This paper presents the iterative design process used in generating several prototypes and proofs of concept for wearable, technological devices which are capable of implementing emotional skins. Reactive layers have the potential to act as visualization surfaces to represent individuals' or groups' emotional configurations depending on the specific strategies which can be applied to a wide range of human activities. These emotionally-aroused, interactive skins can be used in generating cognitive processes which are relevant for social communication, knowledge dissemination and education. The research project aimed at exploring the potential use of these devices in emotion classification and methodologies for representing and enacting dynamics that are significant from cognitive, ethnographic and psychologic perspectives.

Although SignWriting provides an intuitive notation system based on pictorial symbols to enable any sign based language in the world to be transcribed into a written form, it is a time consuming process for keyboard based input. To address the challenge of direct sign writing, the paper presents a human-computer-interaction system developed for recognition and visualisation of hand movements. The system is shown to be able to display the corresponding SignWriting symbols for various hand movements performed by two hands based on motion characteristics such as movement planes, movement directions, straight/curve movement paths, clockwise/anti-clockwise movements, and single/repeated movements.

Volume rendering has been widely used in different fields where several rendering algorithms have been developed, such as shear-warp, ray casting or splatting. But independently of the rendering method, transfer functions are usually used for mapping values and other properties of the volume into colors. As an improvement of transfer functions, style transfer functions are being used, where sphere maps extracted from artwork are used instead of plain colors. In this paper, we propose an interactive designer that would allow the user to create styles in an easy way, and shade them with just a color or a texture. In addition, it guarantees a coherent illumination, making it possible to easily use style transfer functions to achieve realistic rendering.

The multidisciplinary approach to breast cancer treatment in a comprehensive breast center model can deliver a high standard of care for the patient, but it also generates a wide range of patient data that are typically left as disparate silos, and not organized or analyzed for any clinician to help with patient care. We have developed a method for the synthesis of radiology, surgery, pathology, medical oncology, and genetics information from a patient medical history in a timeline paradigm with elements of clinical decision support and quality indicators to help with decision making. A model for structuring data from the many disparate sources was developed to support enriched probing interactions. Summary views of the current knowledge from each discipline were also tightly integrated. To support the surgical management workflow, the prototype lifelines were integrated into existing clinical software, incorporating all the relevant events, decisions, and data elements.

In this paper we describe the long term evaluation of the Website Exploration Tool (WET), an exploratory system for visualising web data, through the assessment of two Virtual Learning Environments (VLE). VLEs provide log files that can be studied with web mining techniques to understand the behaviour of the students and consequently improve the pedagogy. However, statistical metrics are not always easy to interpret for the educators, which suggests the need to develop novel approaches for the easy discovery of usage patterns. The integration of WET in the assessment process of two VLEs gave us the opportunity to conduct long-term case studies that supported the evaluation of the visual approaches used in our tool. Our main contributions are the description of the benefits of such approaches for the analysis of VLEs as well as recommended features for supporting this task, and a summary of the main findings from our case studies.

Although the application of sketch-based chart annotation is not pervasive in management, the use of sketchmarks can provide numerous benefits to managerial discussions. The collaborative use of chart annotations can support management teams in their decision making based on quantitative charts by visually eliciting and capturing interpretation processes, clarifying basic assumptions, stimulating different perspectives, and extrapolating trends into the future. Sketch-based annotations combine the simplicity and immediacy of drawing with the clarity and richness of charting. In this paper, we provide the rationale for this under-researched visual management and communication practice, illustrate it through examples, and – as our main contribution – provide a first overview classification of the different sketchmarks that management groups can use in their discussion of quantitative charts (for such contexts as strategy or project reviews). In the end of the paper we briefly describe our future research in this area and highlight implications for management.

An experiment was conducted to add empirical evidence whether the use of visualization is better than text in the communication of business strategies. Seventy-four managers who took part in an Executive MBA program saw a presentation of the simplified strategy of BMW Financial Services. The visual support of the presentation was manipulated by the author and the according effects were measured. Three different types of visual support were chosen: text in the form of PowerPoint (1), visualization in the form of a visual metaphor (2), and a roadmap (3). Each subject saw only one of the three types of visual support. The effects measured were attention, comprehension, agreement and retention. In addition the perception of the visual and the perception of the presenter were measured for each of the three conditions. Subjects who were exposed to visualization in the form of visual metaphor and roadmap paid significantly more attention to the strategy, agreed more with the strategy and recalled the strategy better than did subjects who saw text in the form of PowerPoint. No significant superiority was found for visualization compared to text in understanding the strategy. Subjects who were exposed to visualization in the form of visual metaphor and roadmap perceived the visual and the presenter significantly better than did those subjects who where exposed to text in the form of PowerPoint. In addition the perception of the visual accounted for 69% of the variation of the perception of the presenter.

Visualization of graphs containing many nodes and edges efficiently is quite challenging since representations generally suffer from visual clutter induced by the large amount of edge crossings and node-edge overlaps. That problem becomes even more important when nodes positions are fixed, such as in geography were nodes positions are set according to geographical coordinates. Edge bundling techniques can help to solve this issue by visually merging edges along common routes but it can also help to reveal high-level edge patterns in the network and therefore to understand its overall organization. In this paper, we present a generalization of [18] to reduce the clutter in a 3D representation by routing edges into bundles as well as a GPU-based rendering method to emphasize bundles densities while preserving edge color. To visualize geographical networks in the context of the globe, we also provide a new technique allowing to bundle edges around and not across it.

The orientation towards data in arts, humanities and pop culture in recent years brings a renewed interest in realism and iconoclasm. The various APIs (Application programming interfaces) and mashups that are employed in these traditionally “qualitative” disciplines offer tools for creative and often critical interpretations. Data are becoming means of a critical distance to the visual and media saturated world that bring whole new perspective on our everyday life and reality. These emerging critical and visual practices define a realism based on data rather than on human perception, reason or some strong ontological theses. This data oriented realism does not simply represent reality but performs the modern processes of its construction with an almost iconoclastic fervor. It offers a distance from the power and seduction of the (digital) image and asks questions about their conditions of possibility, methods of gathering and the various possibilities of their representation. Visualization of various data in the form of popular user generated mashups, serious art visualizations and new digital methods in humanities create a tension between the new forms of iconoclastic realism and the more playful dada collage techniques that are satirical and rather than realist and emancipatory rather than iconoclastic. The use of visualizations in art, humanities and online popular culture (cyberculture) is defined by this tension between data realism to dada “aggregations”.
