    Rapid Serial Visual Presentations (RSVPs) mimic the riffling of a book's pages and are widely employed as a way of gaining familiarity with a collection of images or selecting images of interest from a collection. In a typical RSVP a number of images within a collection enter a display in (say) the lower left-hand corner and move towards the opposite corner where they disappear ('diagonal RSVP'). ...

    Image browsing techniques thus become increasingly important for overview and retrieval of particular images in large-scale collections. At the same time, there are various sets of images which are associated with multi-dimensional or multivariate datasets. We believe that image browsing for such datasets should be inspired from multi-dimensional data visualization techniques. This paper presents ... View full abstract»

    We introduce a novel technique for visualizing dense time-varying directed and weighted multi-graphs with an additional hierarchical organization of the graph nodes. Combining Indented Tree Plots and TimeRadarTrees, we show the temporal evolution of relations in a static view. The graph edges are layered around thumbnail wheels consisting of color-coded sectors that are representatives of the grap... View full abstract»

    A bipartite graph consists of a set of nodes that can be divided into two partitions such that no edge has both endpoints in the same partition. A semi-bipartite graph is a bipartite graph with edges in one partition. Anchored map is a graph drawing technique for bipartite graphs and provides aesthetically pleasing layouts of graphs with high readability by restricting the positions of nodes in a ...

    Nowadays, a great amount of data is created and distributed on the Internet. Tagging has become common practice to structure these data for easy access. Often the data and the associated tags contain spatial and temporal information. In this paper, we develop general design strategies for visualizing spatially and temporally referenced tags similar to tag clouds on maps. Temporal information of ta... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (397 KB) | HTML iconHTML

    This paper studies the idea and feasibility of using a cube metaphor as a graphical user interface for exploring large music collections. In the implemented prototype, new music recommendations and related information are generated on the different faces of the cube based on the selected genre. In a user study with 40 participants, the cube was seen as an interesting and playful new concept that h... View full abstract»

  • Visualizing the Effects of Logically Combined Filters

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1762 KB) | HTML iconHTML

    Filtering data is an essential process in a drill-down analysis of large data sets. Filtering can be necessary for several reasons. The main objective for filters is to uncover the relevant subsets of a dataset. Another, equally relevant goal is to reduce a dataset to dimensions to which either visualization or algorithmic analysis techniques scale. However, with multiple filters applied and possi...

  • Combined vs. Separate Views in Matrix-based Graph Analysis and Comparison

    While much work has been done in the area of visualization for analysis of graphs, relatively little research exists into how best to use visualization for comparing graphs. We have developed a suite of general graph comparison questions that can be tailored to specific data sets, and compared the use of superimposed and juxtaposed views of graph matrices on an example data set. Our observations i... View full abstract»

  • Concentric Sliders to Display Partial Satisfaction of Query Criteria

    Publication Year: 2011, Page(s):59 - 64
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (941 KB) | HTML iconHTML

    This paper describes a new approach called concentric planar slider to visually build queries and to pilot a data view. The purpose of this approach is to go beyond the binary satisfaction of the query criteria(satisfied vs. not satisfied). This UI control helps the user to know to what extent the dataset elements satisfy them. Two interactive sliders are combined in a planar setting. This plane i... View full abstract»

    Networking attacks embedded in spam emails are increasingly becoming numerous and sophisticated in nature. Hence this has given a growing need for spam email analysis to identify these attacks. The use of these intrusion detection systems has given rise to other two issues, 1) the presentation and understanding of large amounts of spam emails, 2) the user-assisted input and quantified adjustment d...

    Frequency-based statistical charts are the most widespread visualizations and the preferred of Infovis novices. They are important in depicting categorical data and providing data abstraction on large datasets. The drill down feature enables better visual scaling by allowing navigation through aggregation hierarchies. In this paper we discuss design considerations that impact on the usability in d...

  • A Task Based Performance Evaluation of Visualization Approaches for Categorical Data Analysis

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (770 KB) | HTML iconHTML

    Categorical data is common within many areas and efficient methods for analysis are needed. It is, however, often difficult to analyse categorical data since no general measure of similarity exists. One approach is to represent the categories with numerical values (quantification) prior to visualization using methods for numerical data. Another is to use visual representations specifically designe... View full abstract»

    The objective of this paper is to show how approaches for user-centered information visualization design and development are being applied in the context of healthcare where users are not familiar with information visualization techniques. We base our design methods on user-centered frameworks in which 'prototyping' plays an important role in the process. We modify existing approaches to involve p... View full abstract»

    The issue of multiple views coordination became more and more challenging in the architecture, engineering and construction (AEC) field since the apparition and the increasing success of 4D/nD CAD. In order to adapt visualization to user's business requirements in 4D-supported collaborative tools, this paper propose a method to design coordinated multiple views based on Model-Driven Engineering (M...

    Alarm management is a crucial part of many industrial systems used in generation, transmission and distribution of electric power as well as in production processes, for example in steel mills and oil refineries. Filtering of important alarms from unessential alarms is a critical task for operators of such systems, since failures may result in severe abnormal situations such as plant shutdowns. Cu...

    This paper studies the idea of using potentiometers as a graphical user interface for interacting with a music recommendation service. In the implemented prototype, the user selects a musical genre and adjusts tempo and energy level potentiometers to fine-tune the play list of new music recommendations. The look of the interface is changed to reflect the currently selected genre. In a user study w... View full abstract»
