ArtVis Dynamic Network Perspectives on Digital Art History

In order to better understand the history of art a major challenge of Digital Art History (DAH) is to understand how the components of the art system (persons, objects, places, institutions, and events) interacted with each other and how these interactions vary over time. The aim of our project is to model such complex relations through the use of Network Visualization (NetVis). Networks have a wide range of application in many domains, including social sciences, software engineering, and economics.

DoRIAH: Domain-adaptive Remote sensing Image Analysis with Human-in-the-loop

Analyzing remote sensing images on a large scale requires to balance two major constraints: accuracy of results and the time it takes to process the images. Using human analysts to accomplish the goal usually provides highly accurate results, but is often not feasible in large-scale scenarios due to the sheer amount of image data to be processed. Consequently, fully automatic image analysis approaches are widely considered but often lack the accuracy needed for the specific problem domain.

GuidedVA: Guidance-Enriched Visual Analytics for Temporal Data

Although Visual Analytics provides advanced techniques to tackle complex analysis scenarios, it still challenging for analysts to discern which VA methods to use for particular data and tasks.

KAVis: Visual Interactive Space-Time Segmentation

Many application domains generate and analyze multivariate spatial time series and often face data quality issues. Segmentations are very useful for exploratory analysis of these varying data characteristics, but appropriate segmentations are currently challenging or frequently impossible. The project aims to integrate background and domain knowledge within a VA process to provide knowledge-assisted interactive segmentation of such multivariate spatial time series and deal with data quality issues (e.g., missing and uncertain values). 

SANE: ViSual ANalytics for Event-based Diffusion on Networks

We strive to systematically characterize the topic in the visualization research community, developing a common framework to foster research in the area. We will then employ such framework to introduce and refine prototypes to analyze real data about diffusion phenomena, improving current algorithmic solutions, and sharing best practices and lessons learned throughout the project duration.

Visual Analytics and Computer Vision Meet Cultural Heritage

Collections of digitized cultural artifacts offer immense potential to increase the knowledge of our heritage. However, the systematic analysis and presentation of historical photographs and amateur films are still strongly limited. This impedes the analysis, interpretation, and subsequent preservation of human cultural history.

A-Plan

User and task analysis

To illustrate the problem, all tasks and the currently used software were investigated. We found many usability problems in the existing software system (SAP CRM). The process of an incoming call is illustrated here:

AsbruFlow - Interactive Information Visualization to Support Protocol-based Care

Based on the Software Prototype CareVis, this project is an approach to communicate the complex logic of Asbruplans to domain experts like physicians or nursing staff. 

Blind Source Separation in Time and Space

There is nowadays an abundance of measurements which are taken at specific locations and / or repeatedly over time. For the resulting multivariate spatial, temporal and spatio-temporal data it can often be assumed that there is a lot of noise in the data and only a few latent signal components carry all the relevant information.

CareVis - Interactive Visualization Methods to Support Protocol-Based Care

We provide multiple simultaneous views to cover different aspects of a complex underlying data structure of treatment plans and patient data. The tightly coupled views use visualization methods well-known to domain experts and are designed to facilitate users' tasks. CareVis enables a meaningful navigation, provides annotations on demand for not overwhelming the viewer, and helps to keep orientation by using focus+context techniques, thus increasing the flexibility in working with treatment plans and patient data.

CPGPro – Extracting Process Information from Clinical Practice Guidelines

Like in many other domains, computerization is seen as a means to facilitate the effective use of Clinical Practice Gudelines (CPGs). Therefore, transforming CPGs in a machine-readable and executable format has been the gist of research. Consequently, many guideline representation languages are developed and modelling tools are designed which convert CPGs in their corresponding models defined in these guideline representation languages. Available modelling tools are restricted in the way that they only allow a manual computerization process.

CVAST - Centre for Visual Analytics Science and Technology

CVAST aims to design and  develop innovative methods for data interpretation to capture the daily flood of information in interactive visualizations and analyses. Scenarios that involve temporal properties of such data are in the focus of our scientific interest.

DAD - Digital Aided Guide for Fathers-to-be

The aim of this project is the implementation of the “Digital Aided Guide for Fathers-to-be” in several participating partner countries. This guide has been well established in Austria since 2004 and has evolved from a project at the Danube University Krems (Austria). In order to achieve a successful market launch, the project’s partners from Poland, the Czech Republic, Romania and the Netherlands will adopt the Austrian service according to their national cultural, social and legal circumstances.

DeTable – A Wrapper for Complex HTML Tables

The main purpose of this student project is a wrapper that transforms complex HTML tables into an XML format. The complexity of the HTML tables is defined by the occurrence of spanned cells.

DeVisOR - Detection and Visualization of unexploded Ordnance Risks

Analysis of historic air photos (images) with the goal of detecting unexploded bombs is a niche task, yet extremely important for preventing great damage or even loss of life. The computer science techniques and software tools currently available are of general nature, like Geographic Information Systems (GIS) and graphics editing programs.

DisCō - Visual DIScovery and COmmunication of complex time patterns in non regularly gathered multigranular and multivariate data

The capabilities to generate and collect data and information have seen an explosive growth and overwhelm traditional methods of data analysis such as spreadsheets, ad-hoc queries, or simple visualizations. Exploring trends, patterns, and relationships are particularly important when dealing with large amounts of data. The human perceptual system is highly sophisticated and specifically suited to spot visual patterns.

Doctoral College: Environmental Informatics

In recent years, Environmental Informatics has emerged as a new interdisciplinary research field that can facilitate decisions regarding social, economic, ecological, and environmental goals based on a variety of information technology measures.

Dynamic XML Query Table Editor (DQT)

DQT supports the creation of such databases as well as their presentation and includes the following features:

EvalBench: A Software Library for Visualization Evaluation

To pave the way for future experimenters in the HCI field, the Java software library EvalBench was developed that focused on flexibility and reusability and should be easy to integrate into existing Java visualization applications.

EviGuiDe –  Embedding the Evidence Information in Computer-Supported Guidelines into the Decision-Making Process

In this project we propose a methodology that supports guideline users during the decision-making process on the basis of a semi-formal representation of the evidence information that can be found in Clinical Practice Guidelines (CPGs). A semi-formal representation is required to handle evidence information in computer-interpretable guideline representation languages. For this purpose, we have developed a meta schema that covers various kinds of grading systems including graded and ungraded evidence informaton.

EviX – Facilitating Evidence-based Decision Support Using Information Extraction and Clinical Guidelines

The goal of the proposed project is the experimental application and further development of promising approaches in the area of semi-automatic creation of computer-interpretable clinical guidelines and the execution of evidence-based recommendations. We expect contributions to ease the creation of computer-interpretable guidelines and support of the medical staff in their daily routine and decision-making.

EXPAND: EXploratory Visualization of PAtent Network Dynamics

The distributed nature of modern research and development has lead to a highly differentiated knowledge and technology landscape, which forms the complex and continuously evolving environment for individual and organizational actors in the economy, science, and technology realm. Public patent databases, which are regulating these developments by ongoing accumulation of semi-structured patent documents, are a rich source of information that has not been sufficiently leveraged for synoptic science and business analytical tasks yet.

FinanceVis - Design and Evaluation of Visualization Methods to Compare Multivariate Time Series

The comparison of several stocks against each other is an important task in financial analysis. The data is usually compared by juxtaposition or by superimposition. But even a large enough difference between the price ranges can make a simple comparison of the data difficult.

Stock market data is not limited to stocks. It also includes stock (market) indices such as the Dow Jones and NASDAQ. Stock indices have their own proprietary unit, which is different to the unit of a stock. Time series which have different units are also called heterogeneous data.

FishEye JTree

The Java Swing element "JTree" allows representation and navigation in tree structures. But as soon as the amount of hierarchical data structures increases (e.g. the file system) one can easily lose overview and orientation while navigating through different nodes on deep hierarchic levels.
