For communication of design plans, city councils and other local governments require that 3D models are developed quickly, at minimum expense, and they can be made available online. Users, generally citizens, increasingly expect that the models are a photorealistic and truthful representation of the future situation. Despite the advancements in graphics in recent years, the budget, the platform available, and the requirements of use are restraining factors for the visual quality of a 3D model. The question of the validity of models for assessment of urban development plans is therefore increasingly relevant. In this empirical field study we compared the affective qualities of a 3D model designed for online assessment and communication of urban development, with those of the urban environment in reality. The model was considered more pleasant, more modern and more uniform than the area in reality. This can be explained by specific characteristics of this type of model, such as the lively colours and the clean surfaces.

Searching and exploring on digital maps are normally performed through simple text boxes and zoom-and-pan interfaces. In this paper, however, we present a novel technique, namely Taggram, which combines texts onto maps to support geo-tagged data exploration. It is designed to show geo-tagged data in form of size-varied and colorized tags, benefiting by the concepts of Tag Clouds, and to support exploring those data interactively through a fisheye menu adaptation. The technique was demonstrated for geo-tagged data exploration; however, as other thematic geo-data can be partially represented in abstract form of texts, Taggram can be a method for the presentation and exploration of such geo-data in other application scenarios.

This paper presents an exploratory empirical study about users’ reception and usage behavior with interactive information graphics. 14 participants took part in the study. We assume users to act interest-driven. Therefore no explicit tasks were assigned to participants. In order not to distract the user, retrospective thinking aloud was employed. Results show that (1) usage durations were heterogeneous between users and between different types of interactive information graphics; (2) users tended to watch introductory animations; (3) initial orientation without interaction on the first content screen (after intro) was rather long with 23 seconds on average; (4) story-based approaches seem to motivate users but might lead to less intensive reception of information; (5) several reception and usage problems have been identified regarding information presentation and interaction. Interactive information graphics tend to overwhelm users with too much information and disregard well-known principles and rules of the old media and web design.

In the analysis of spatially-referenced time-dependent data, gaining an understanding of the spatio-temporal distributions and relationships among the attributes in the data can be quite difficult. We present a visualization technique that addresses some of the challenges involved in visually exploring and analyzing the distributions of geo-spatial time-varying data. We have developed a pictorial representation that is based on the standard space-time cube metaphor and provides in a single display the overview and details of a large number of time-varying quantities. Our approach involves three-dimensional graphical widgets that intuitively represent profiles of the time-varying quantities and can be plotted on a geographic map to expose interesting spatio-temporal distributions of the data. We show how combining our visualization technique with standard data exploration features can assist in the exploration of salient patterns in a data set. The visualization approach described here supports expeditious exploration of multiple data sets; this in turn assists the process of building initial hypotheses about the attributes in a data set and enhances the user's ability to pose and explore interesting questions about the data.

The human vision can naturally interpret data in spaces of 2 or 3 dimensions. When data is in higher dimensional spaces, in most cases the visualization is not intuitive. Regarding metric spaces, the interpretation is even harder, since they often do not have a direct spatial representation. However, the need to analyze how metric-represented data evolve over time is pretty common when one needs to understand several phenomena and in decision making processes, as it occurs in medical and agrometeorological applications. This paper presents three interactive techniques to visualize metric data that vary over time. Each one focus on a different way to interpret the temporal information. The first technique shows data evolving in a timeline axis. The second overlaps evolving snapshots of the space showing how the space varies regarding time. The last one does not treat temporal data as a dimension, it is used instead to define the similarity among complex data, employing the new concept of metric-temporal spaces, which seamlessly integrate time and metric data into a single similarity space. Visualization examples with real datasets are presented to show the usefulness of the proposed techniques.

The transition from ephemeral, ceremonial art to more permanent acrylic-on-board paintings has made Australian Aboriginal art more accessible to the public than ever before. However, early examples contained secret/sacred motifs and stories - knowledge recorded in the paintings that was normally only made available to initiates. In turn, this prompted contemporary Australian Aboriginal artists to hide, camouflage or remove the sensitive material from their work. It is only recently, through inter-gender and inter-cultural collaborations between contemporary Indigenous Australian artists and non-indigenous ethnographers and anthropologists, that the full ramifications of this transition is becoming apparent. This paper discusses 3 case studies where the traditional expression of Kuruwarri, or Ancestral power, has been transformed through contemporary Australian Aboriginal women’s art.

The wide variety of visualization methods for numerical values have, up until now, outweighed the relatively modest selection available for nominal dimensions. Theme Landscape is a visualization application designed for tagged data that typically contains a large number of nominal dimensions. It provides an overview of large data volumes, doing so by positioning objects in a landscape according to how similar their tags are. HexBoard technology has been used for dimension reduction. A further distinctive feature of Theme Landscape concerns the icons. The tags that belong to an object can be identified according to the shape of its icon. Each keyword is assigned to its own unique glyph and these glyphs form, in any combination, a hexagonal icon. For the prototype a data archive of interactive media artworks has been used, which had been tagged using a taxonomy.

Despite the growing number of systems providing visual analytic support for investigative analysis, few empirical studies include investigations on the analytical reasoning process that needs to be supported. In this paper, we present an approach to evaluate the ability of certain visual representations from an integrated visual-computational environment to support the completion of representative tasks. The problem area studied is the detection and identification of anomalous vessels and situations while monitoring maritime traffic data. This paper presents: (1) a brief review of current evaluation methodologies within information visualization and visual analytics, (2) an analysis of operator's analytical reasoning process (derived from field work in maritime control centers and a literature review on analytical reasoning theories), (3) a list of representative tasks for usability evaluation and (4) an approach to evaluate the use of normal behavioral models representations during the detection process.

Highlighting was the basic viewing control mechanism in computer graphics and visualization to guide users’ attention in reading diagrams, images, graphs and digital texts. As the rapid growth of theory and practice in information visualization, highlighting has extended its role that acts as not only a viewing control, but also an interaction control and a graphic recommendation mechanism in knowledge visualization and visual analytics. In this work, we attempt to give a formal summarization and classification of the existing highlighting methods and techniques that can be applied in Information Visualization, Visual Analytics and Knowledge Visualization. We propose a new three-layer model of highlighting. We discuss the responsibilities of each layer in the different stage of the visual information processing.
