Modern mobile IT-systems offer a great potential for various applications and enable a user to work autonomously, to communicate or to retrieve information nearly everywhere. However, displaying information outdoors is still challenging for the system designer. Numerous approaches of augmented reality (AR) tend to integrate additional information into the real context of the user's environment. Using...
Maestro - 3D group calendar visualizer aims at handling multiple schedules and highlighting common free times. One of the most powerful skills of Maestro is scalability according to the number of group members, which can be up to 18 users. The use of color and shape intends to create a more lucid picture of an organizationpsilas schedule, as opposed to traditional calendars which can overwhelm the...
We present three information visualizations for studying social stratification. Each Web-based applet uses a different metaphor to display U.S. Census income data along with the categories of race, marital status, and profession. Each system is completely dynamic, affording the user the choice of categorical variable to compare, as well as the choice of categories within each visualization. Two different...
Technology has enabled mega-collaboration on an unprecedented scale. A tool is needed to coordinate these activities and link them to government response efforts. However, in defining and responding to problems, teammates need to be able to visualize each other's mental models. The tool must encourage the team to advance promptly through team "forming, norming, storming, and performing."...
While traditional computer graphics research to this day still focuses on the production and assessment of photorealism, a relatively new field, the one of nonphotorealistic rendering (NPR), has produced results that focus on viewer engagement by the use of stylization, abstraction and expressiveness. In this paper we briefly describe some of the techniques used today and then proceed to identify...
The aim in this work was to develop a method to visualize log files produced by a pilot study of an experimental e-learning platform. The e-learning system running on a web server generated detailed descriptions of its usage that were analyzed. The log files were produced to allow the project's researchers to study offline how the system was utilized. We used open-source software tools to create a...
With a history of over 300 years, the chemical table is the textbook case of information visualization. This paper explores the development of the chemical table as a tool designed for chemical information visualization. It uses a historical context to investigate the purpose of chemical tables and charts, and suggests reasons why the two-dimensional periodic table remains the de facto standard for...
The surveillance of large sea areas often generates huge amounts of multidimensional data. Exploring, analyzing and finding anomalous behavior within this data is a complex task. Confident decisions upon the abnormality of a particular vessel behavior require a certain level of situation awareness that may be difficult to achieve when the operator is overloaded by the available information. Based...
Time series analysis poses many challenges to professionals in a wide range of domains. Several visualization solutions have been proposed for exploratory tasks on time series collections. For large data sets, however, current techniques fail to provide a global view that supports a good association between groups of similar time series. We employ fast multidimensional projection techniques to create...
A 3-dimensional variant of the 'polymetric views' approach for visualising metrics within an object oriented software system is presented. This variant provides simultaneous display of several metrics including coupling, the contribution made by coupling to interface rather than to concrete class, and an indication of behavioural polymorphism. A tool, JCTIViz, is described that implements this visualisation...
In many application fields, the statistical properties of data sets are of great interest for data analysts. Since local variations can occur especially in large datasets, it is useful to visualize not only global values, but also the properties of user-defined subsets. Hence, we present in this paper a visualization of the statistical characteristics of subsets, with an emphasis on the temporal development...
We describe a case study of TaxVis, a multiple view system for examining relationships between sets of multiple classification trees. The system displays multiform views of the dataset, which in turn can either be a singular view of the larger forest object formed from the set of trees, or multiple views in themselves, using linking to show relationships between the separate trees. We describe the...
In this paper, we present an interactive matrix-based multi-dimensional visualization component which enables the users to explore a text collection along different conceptual dimensions. Of importance in our approach are the tight coupling of the users' personal ontologies representing their spheres of interest with the visualization component and the application of barycenter heuristic for edge...
We visualize 113 years of bibliographic data from the American Physical Society. The 389,899 documents are laid out in a two dimensional time-topic reference system. The citations from 2005 papers are over laid as flow maps from each topic to the papers referenced by papers in the topic making intercitation patterns between topic areas visible. Paper locations of Nobel Prize predictions and winners...
For successfully competing in a modern economy, large amounts of hierarchic time-dependent data need to be analyzed. As an example, one could consider the geographic composition of inflation in the European Union, or the revenue by product (sub) categories of a firm in the last month. Analysts wish to interpret the structure of the data not only at a single point in time, but examine the changes in...
This paper presents the design of a new web browser, the Tree Trailblazer, which allows users to browse the web while maintaining a visual record of their exploration path, or trail, through the information space. This design enhances the backtracking aspects of web browsing over current designs by providing visual cues regarding the pages related to the page being viewed, providing users with an...
There have been many attempts to create software that would allow the users to design SQL queries visually, even though it is not very natural to handle relations and relational algebra (the theoretical background of SQL) this way. But the RDF data format is based on directed labeled graphs, whose visual representation is very natural. We have created an RDF visualizer and tried to extend it to support...
