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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
