Data visualization is a powerful tool to cope with the demands of our current information age. In order to understand and being able to develop visualizations for specific use cases, data visualization activities (vis activities) have been proposed in recent years. These highly effective tools focus on practical relevance, reflection, and discussio...

Rigorous data science is interdisciplinary at its core. In order to make sense of high-dimensional data, data scientists need to enter into a dialogue with domain experts. We present Glyphboard, a visualization tool that aims to support this dialogue. Glyphboard is a zoomable user interface that combines well-known methods such as dimensionality re...

Suchmaschinen bieten Zugang zu großen Datenmengen und viele Möglichkeiten, die Nutzeranfragen zu interpretieren und mit Empfehlungen zu unterstützen. Neben diesen technologischen Vorteilen hat sich am Suchparadigma selbst in den letzten Jahren wenig geändert. Die meisten Suchinterfaces bestehen auch heute noch aus den typischen Eingabemasken und li...

In recent years, many novel approaches have been proposed for the exploration of complex, multidimensional data sets. However, little guidance is available for d...

Business Intelligence applications often handle data sets that contain uncertain values. In this contribution, we focus on product costing, which deals with the average costs of product components-that vary significantly based on many factors such as inflation, exchange rates, and commodity prices. After experts estimate the uncertainty information...

Conversation training is an e-learning method for the transfer of communication-related skills. With the increasing complexity of these conversations, such as length or structure, combined with the number of learners, the evaluation and analysis of the resulting data set become a challenging task. In this paper, we present a visualization approach...

When working with a given high-dimensional data set, data analysts often use different machine-learning algorithms to calculate clusters and classifications. However, it is difficult to ascertain which differences occur across these algorithm versions. For a human-readable visualization, dimensionality reduction methods are used to achieve two-dime...

In recent years, many novel approaches have been propsed to exploring complex data sets. However, little guidance is available for designers to create similar solutions and to reuse established patterns. This paper is building upon our previous work that covers the development of a construction kit to support designers in creating new visual search...

With the internet, massively heterogeneous data sources need to be understood and classified to provide suitable services to users such as content observation, data exploration, e-commerce, or adaptive learning environments. The key to providing these services is applying machine learning (ML) in order to generate structures via clustering and clas...

Industrial applications can benefit considerably from the overwhelming amount of still growing resources such as websites, images, texts, and videos that the internet offers today. The resulting Big Data Problem does not only consist of handling this immense volume of data. Moreover, data needs to be processed, cleaned, and presented in a user-frie...

Business Intelligence applications often handle data sets that contain uncertain values. In this work we focus on product costing, which deals with the average costs of product components - that vary significantly based on many factors such as inflation, exchange rates, and commodity prices.

Data Analysts have to deal with an ever-growing amount of data resources. One way to make sense of this data is to extract features and use clustering algorithms to group items according to a similarity measure. Algorithm developers are challenged when evaluating the performance of the algorithm since it is hard to identify features that influence...

received Best Paper Award A novel generation of (e.g. touch-driven) applications leads to a new universe of interaction paradigms and a growing need for simple, inspiring and smart interfaces. A system intended for non-experts should only present information the user needs to solve his task, instead of confronting him with the large and complex un...

As the 'gatekeepers' of the internet, search engines provide access to a huge amount of data. Nowadays, many search engines are able to interpret user queries and automatically suggest additions or corrections. Despite these technological advances, the search paradigm itself remains stable for most engines. Especially for users with little knowledg...

Faceted browsing is an established and well-known paradigm for product search. However, if the user is unfamiliar with the topic and the provided facets, he may not be able to sufficiently reduce the amount of results. In order to increase the understanding of the bidirectional relation between facets and result set, we present an interface concept...

The use of metaphors can support the understanding of novel interfaces approaches and increase the ease of use. But the design of novel holistic and adaptable metaphors is still challenging for interface designers. While most literature provides no systematic instruction for metaphor design or recommend to use a repertoire of known metaphors, we pr...

TagStar is designed to support users during the classification of data items based on a multidimensional classification scheme. We also intend to support experts when analyzing the database. Analytic features of the presented visual indexing system allow experts to discover insufficiently described resources with little effort. The resulting interf...

The periodic table is the first means of chemists to structure their field of research. It comprises all chemical elements with their most prominent features. The system is so important that students of chemistry usually learn it by heart during their university education. Scientists in the field of human-computer interaction lack such a concise sy...

Interaction design for mobile applications is challenging due to the diversity of technologies and devices. In addition, the now ubiquitous multi-touch screens demand novel and engaging interface metaphors. In this paper, we report insights and three practical results from a workshop with undergraduate students. The aim was to experiment with new t...

In complex search scenarios like planning a vacation or finding a suitable gift for a friend, the user usually does not know exactly what he is looking for at the beginning. However, this is the question that most search interfaces present as first step. In this paper, we discuss approaches for supporting the user in expressing a search query based...

Software tools for project management are extremely complex desktop applications. Recently, we observe a shift from traditional project management where one project manager is responsible for creating the project plan and supervising its execution, towards a more agile multi-project management that involves project members early in the planning pro...
