The purpose of the visualization is twofold: first to expose the implicit structure in subject headings as an overview of a library collection and second to present a visual web of keywords to invite exploration of books. Taking a tag cloud as a starting point, the visualization extends it to a networked tag cloud that respects the hierarchy that is implicit in subject headings. By allowing an information seeker to successively build a subject filter, while seeing the results at each step, we hope to improve the searcher’s orientation in a comprehensive book collection.

Building on the work of sociologists Gabriel Tarde and Bruno Latour we turn to the concept of the monad as a useful lens on online communities and collections that expands the possibility for creating meaning in their navigation. While existing interfaces tend to emphasize either the structure of the whole or details of a part, monadic exploration brings these opposing perspectives closer together in continuous movements between partially overlapping points of view. We present a visualization that reflects a given node's relative position within a network using radial displacements and visual folding. To investigate the potential of monadic exploration we report on an iterative design process of a web-based visualization of a highly cross-referenced book and its six-month deployment.

[i.e. 9 - 14 November] 2014, Paris, France N2 - We created a pixel map for multivariate data based on an analysis of the needs of network security engineers. Parameters of a log record are shown as pixels and these pixels are stacked to represent a record. This allows a broad view of a data set on one screen while staying very close to the raw data and to expose common and rare patterns of user behavior through the visualization itself (the "Carpet"). Visualizations that immediately point to areas of suspicious activity without requiring extensive filtering, help network engineers investigating unknown computer security incidents. Most of them, however, have limited knowledge of advanced visualization techniques, while many designers and data scientists are unfamiliar with computer security topics. To bridge this gap, we developed visualizations together with engineers, following a co-creative process. We will show how we explored the scope of the engineers' tasks and how we jointly developed ideas and designs. Our expert evaluation indicates that this visualization helps to scan large parts of log files quickly and to define areas of interest for closer inspection.

Working with a newly acquired archive of contemporary poetry we produced designs that both manifested and "geared in to" [Durrant 2011] [Gurwitsch 1979] the temporal rhythms of the work and infrastructure of archiving. Drawing on user-centred work with participants, often poets themselves, we focused on marginalia as a material feature of the archive, developing a drawing machine and live Twitter bot. Our work addresses institutional concerns for outreach and engagement while also acknowledging and exploiting the inevitably incomplete or live character of archival collections. For designers working with digital archives, we demonstrate the pragmatic and critical value of liveness as a focus of the design process.

Berliner Veranstaltung der internationalen EVA-Serie N2 - Im Rückgriff auf Ausstellungspraktiken im Museum stellt der Artikel Bezüge zwischen Erkenntnissen aus der Visualisierungsforschung und der Rezeption von Museumssammlungen in einem Ausstellungsdisplay her. Besondere Beachtung finden hierbei Makro- und Mikroperspektiven auf Sammlungen und Darstellungen im (digitalen) Display eines Museums. Visualisierungen können einen offenen und explorativen Zugang zu den digitalisierten Beständen bieten, der eher den Ausstellungs- und Vermittlungsaktivitäten des Museums entspricht oder diese ergänzt. Dabei werden die Potenziale der digitalen Präsentation herausgearbeitet und Anhand von Use Cases aus der Forschung illustriert, welche Ansätze in der facettierten und „kuratierten“ Inszenierung von Sammlungen umgesetzt werden können.

BT - An experimental visualization of personal movement data N2 - Shifted Maps proposes a novel visualization method to generate personal geovisualizations of individual movement data. The resulting visual appearance can be characterized as a map network consisting of visited places and their connections. The visited places are shown as circular map extracts scaled according to the time spent there and the movements between the places are represented as edges between the places. A key feature of the Shifted Maps visualization is the possibility to explore the data in three different arrangements based on geo-spatial position, travel time, and frequency of movements. By combining map and network visualizations of movement data, it becomes possible to analyze and compare spatial and temporal topologies.

Projection techniques generally aim to make a high-dimensional information space visible in form of a planar layout. However, the meaning of the resulting data projections can be hard to grasp. It is seldom clear why elements are placed far apart or close together and the inevitable approximation errors of any projection technique are not exposed to the viewer. Previous research on dimensionality reduction focuses on the efficient generation of data projections, interactive customisation of the model, and comparison of different projection techniques. There has been only little research on how the visualization resulting from data projection is interacted with. We contribute the concept of probing as an integrated approach to interpreting the meaning and quality of visualizations and propose a set of interactive methods to examine dimensionality-reduced data as well as the projection itself. The methods let viewers see approximation errors, question the positioning of elements, compare them to each other, and visualize the influence of data dimensions on the projection space. We created a web-based system implementing these methods, and report on findings from an evaluation with data analysts using the prototype to examine multidimensional datasets.

We argue the case for recognising this digital shift as an opportunity to create interfaces to cultural heritage that are, first of all, more inviting to the public. Secondly, we want to encourage critical approaches towards the representation of cultural production and allow for alternative or even conflicting narratives and interpretations to surface. We present related work, use cases, and concepts for visualisations and interfaces that invite the reconsideration of modes of categorisation, presentation and clustering. Our intent is to develop ways to scrutinise modes of exclusion, carry out critical evaluations and pursue interventional strategies. We discuss the specific potential of visualisation, annotation and dynamic expansion of digital cultural collections. Building on critical approaches in human-computer interaction, visualisation and cultural theories, we explore how the interface could be a means of reflection, critique and inclusion.

We are interested in developing a more playful approach to language that can be characterised by the notion of wandering as an open-ended movement. To support such a casual form of engagement with text, we designed the WordWanderer system: a visualisation technique that extends tag clouds into a navigational interface for text. The tool supports the gradual movement between word ‘context views’, which represent the words that co-occur in the vicinity of the selected word, and word-‘comparison views’, which arrange words based on their association strengths between two selected words. We report on the encouraging feedback from a ten-day deployment of the interface and present promising directions for future design and research.

Challenging an institutionalized understanding of overview and detail as inherently opposed, the intention of this research is to develop a visualization method that accounts for the iconographic abundance of a collection and encourages its casual exploration. Expanding digitization efforts have led to a growing number of rich cultural heritage datasets that are successively being published online. At the same time scholars are exploring the potential of computational methods to expand the scale and scope of art history. In this context, data visualization is often equated with a distanced perspective diminishing the intricate and intriguing details of individual artifacts. In collaboration with a museum of applied and decorative arts, we have devised a novel interface concept for the exploration of image collections such as historical glass plate negatives. Inspired by photographic plates on a light table, the resulting Close-up Cloud translates the art historical method of close viewing into the digital by combining it with a dynamic representation of quantitative iconographic patterns across an entire image collection.
