The design of traffic management systems is challenging because of the large amount of dynamic data which has to be analysed by operators. Systems have to be designed appropriately to enable operators to react efficiently and quickly. The following paper gives an overview of guidelines derived from empirical research in cognitive psychology and HCI. These guidelines specifically address the design of traffic management systems. The following topics seem to be especially relevant: visual perception, geographic data, perception of motion, monitoring of tasks and interaction. These guidelines can help to design usable and useful systems.

Civil Engineering is characterized by the ineffectiveness of production planning and control. The origins of these problems lie in unclear and late information. Augmented Reality (AR) can tackle these problems and help to improve the information flow. This paper describes the benefits of Augmented Reality on construction sites and introduces a smartphone application for an intuitive information retrieval on construction sites. It explains the structure of the application, especially the mathematical calculation of the AR view, and demonstrates its use in a practical case.

Underground caves and its specific structures are important for geomorphological studies. In this paper we present tools to identify and map speleothems by surveying cave chambers interiors. The cave chamber was surveyed using Terrestrial Laser Scanning to acquire point clouds with high level of detail for 3D model generation. This data with 45 million points is useful for either reconstruction, geomorphological studies or virtual visits of caves. With this point cloud we generated a 3D-mesh to represent the surface model of the cave chamber, which is important to study its geomorphological features. A topological structure of the 3D-mesh was also implemented to get an efficient algorithm to help identifying stalactites. The possibility to publish 3D data on the Web is of particular interest for the geospatial field. For this reason, it was decided to make the cave model available in the Web by developing a 3D graphical interface where users can navigate and interact with the three-dimensional models of the cave. For this Web3D framework it was used X3D, WebGL and X3DOM. Such solution does not require any additional plug-ins or components.

We introduce a technique for bundling edges in graphs where a hierarchical organization of the vertices is not available. Instead of applying time-complex force-directed edge bundling, we adopt the concept of Rapidly-Exploring Random Trees (RRTs). We use RRTs for fast computation of a hierarchical space organization that is independent of the spatial structure of the graph layout. Due to this independency, edge bundling can be applied to any graph layout and even allows us to define spatial obstacles through which no bundles may lead. Furthermore, when adding or removing graph nodes and edges on-the-fly, the bundling structure remains stable, which cannot be guaranteed for force-directed bundling. The main benefit of RRT bundling is its high efficiency, supporting interactive exploration. We rely on the low runtime complexity for a new interaction technique for visual clutter reduction in node-link diagrams that we refer to as the RRT edge bundling lens.

Multiple views of data sets from the same domain can support to discover unforeseen associations among data elements, but requires users to interact with them. The coordination mechanism must relate elements across multiple views. The mapping among data elements are constrained by using data attributes, and such mapping influences on how multiple views are coordinated. We propose the application of ontology to link data elements based on semantic for specific context. Representing the underlying data into ontology, semantic representation to create the mappings can benefit exploratory visualization. In this paper we show how to use ontology on coordinating multiple views, the initial results using document collections are presented and discussed, in comparison with traditional techniques.

Project managers increasingly rely on software support for monitoring status and development of projects gathered in large portfolios. The status of a project is characterized by a large number of mostly numerical parameters. Various chart visualisations are commonly used to express parameters, provide aggregation and support comparison. We propose a visual representation which encodes the parameters defining a project's status into a single project symbol. We also propose to visualise project portfolios by applying a two-dimensional layout to collections of project symbols. The resulting project portfolio visualisations empower users to monitor the progress and status of each project, discover outliers, and identify project groups sharing common properties. A user evaluation of the project symbol and of the portfolio visualisations was performed providing directions for further improvements.

This research focused on inserting a computer-generated element into live-action footage, and seamlessly replacing unwanted objects in the footage in order to creating a realistic and seamless visual representation in the field of digital compositing. The purpose of this paper is to cover a detailed working process of digital compositing in order to clarify the production process and provide a clear idea for those entry-level artists to improve an overall understanding of the digital compositing and visual effects and hopefully inspire further collaboration and participants particularly between academia and industry.

This paper takes an information visualization perspective to visual representations in the general SOM paradigm. This involves viewing SOM-based visualizations through the eyes of Bertin's and Tufte's theories on data graphics. The regular grid shape of the Self-Organizing Map (SOM), while being a virtue for linking visualizations to it, restricts representation of cluster structures. From the viewpoint of information visualization, this paper provides a general, yet simple, solution to projection-based coloring of the SOM that reveals structures. First, the proposed color space is easy to construct and customize to the purpose of use, while aiming at being perceptually correct and informative through two separable dimensions. Second, the coloring method is not dependent on any specific method of projection, but is rather modular to fit any objective function suitable for the task at hand. The cluster coloring is illustrated on two datasets: the iris data, and welfare and poverty indicators.

Analysis and monitoring of system logs such as transaction logs and access logs is important for various objectives including trend discovery, update effort determination, and malicious behavior monitoring. However, it is not always an easy task because these logs may be massive, consisting of millions of records containing tens of variables, and therefore it may be difficult or time-consuming to discover significant knowledge. This paper presents a visual analytics tool which enables us to effectively observe system logs. The tool recommends variables that can reveal interesting discoveries and provides feature-based filtering that selects meaningful items from the visualization results. This paper also presents the result of experiments for non-professional users.
