TY - JOUR A1 - Stahnke, Julian A1 - Dörk, Marian A1 - Müller, Boris A1 - Thom, Andreas T1 - Probing Projections BT - Interaction Techniques for Interpreting Arrangements and Errors of Dimensionality Reductions JF - IEEE transactions on visualization and computer graphics N2 - We introduce a set of integrated interaction techniques to interpret and interrogate dimensionality-reduced data. 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.

A1 - Dörk, Marian T1 - Reading Traces: Scalable Exploration in Elastic Visualizations of Cultural Heritage Data JF - Computer Graphics Forum N2 - Through a design study, we develop an approach to data exploration that utilizes elastic visualizations designed to support varying degrees of detail and abstraction. Examining the notions of scalability and elasticity in interactive visualizations, we introduce a visualization of personal reading traces such as marginalia or markings inside the reference library of German realist author Theodor Fontane. To explore such a rich and extensive collection, meaningful visual forms of abstraction and detail are as important as the transitions between those states. Following a growing research interest in the role of fluid interactivity and animations between views, we are particularly interested in the potential of carefully designed transitions and consistent representations across scales. The resulting prototype addresses humanistic research questions about the interplay of distant and close reading with visualization research on continuous navigation along several granularity levels, using scrolling as one of the main interaction mechanisms. In addition to presenting the design process and resulting prototype, we present findings from a qualitative evaluation of the tool, which suggest that bridging between distant and close views can enhance exploration, but that transitions between views need to be crafted very carefully to facilitate comprehension.

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.

Queer archives face the challenge of documenting identities that are inherently characterized by embracing fluidity and ambiguity. Thus, queer identities are diametrically opposed to archival procedures of unambiguous classification. At the same time, queer activism relies partly on coherent identity categories in order to be able to act politically. We examine the pragmatic solutions that queer archives establish when dealing with tensions between those requirements. Our goal is to contribute to the ongoing discussions about the ethical dimensions of classification practices. Following the work of Geoffrey C. Bowker and Susan Leigh Star (1999) we use the concept of boundary objects as a central theoretical foundation of our research. This concept allows for tracing the negotiations and decision-making processes that influenced the creation of a specific classification system. Through conducting semi-structured interviews with staff members of queer archives in Germany we collected data about their efforts to archive the history of queer communities. Although there are initiatives developing metadata standards for queer identities, these standards are only used to a limited extent by the queer archives we examined. Rather, those archives established individual strategies for categorizing objects that are rooted in their specific history. We argue that classification systems and controlled vocabularies themselves can be understood as artifacts documenting the history of queer movements.

Ausgehend von dem Projekt Sharing Knowledge (2014-2020), das im Ethnologischen Museum (Staatliche Museen zu Berlin/ Stiftung Preußischer Kulturbesitz) stattfand, wird argumentiert, dass die Trägheit von Infrastrukturen und die Erforschung ihrer Funktionsweise - d.h. die Entschlüsselung der Meistererzählungen und Ausschlussmechanismen hinter musealen Wissenspraktiken - entscheidende Schlüssel darstellen zur Entwicklung von Werkzeugen und Taktiken, um eben diese Trägheit zu umgehen und zu untergraben. Während der erste Teil des Papiers dem Beispielprojekt kritische Aufmerksamkeit schenkt, schlägt der zweite Teil neue Methoden vor, um Infrastrukturen zu entwickeln, die Relationalität und Pluralität zulassen.

However, it is the often comprehensive and complex nature of collections that can make it difficult to grasp their distribution and extent across a variety of dimensions. After a brief introduction to the research area of collection visualizations, this paper presents a design study visualizing an aggregated collection from diverse cultural institutions in Germany. We detail our iterative design process leading to prototypical implementations of four stylistically and functionally coordinated visualizations, each one focusing on different facets of the collection.

The conventional display of museum objects in online interfaces tends to neglect the physical gestalt of the collection. For example, coins typically end up in tabular grids of thumbnail pages in online collections mimicking their rigid placement in storage drawers of a depot and glass cabinets in exhibitions. The overall aim behind this research was to devise visualizations that do justice to the material and semantic richness of an entire collection, while providing a casual mode of access that is inviting to people with no background in numismatics. To do this, we undertook an iterative design process, which involved a close collaboration with numismaticians and playful ideation with actual coins. Carefully negotiating expert knowledge and lay curiosity, the resulting visualization represents the collection’s dimensions using thousands of thumbnails as visual data points. The coins can be arranged into various layouts such as piles representing, for example, metal types, or streams visualizing the ebb and flow of coins over the centuries. In the interface, one can play with the coins in a manner that would be unthinkable in a physical exhibition and that has not been tried in a digital display. The article reports on the overall research and design process of this project, the resulting interface concept and prototype, and the feedback received during two evaluations.

Yet, there is only a limited understanding of the role of artefacts in the social dynamics in memory. With memory dialogue, we introduce a methodology for exploring artefact-based memory sharing. Participants created physical or digital memory artefacts, exchanged them, and reflected on the process. Our qualitative findings show how this method can help uncover the complexity of shared memory. Participants largely chose bonding experiences and created artefacts as conversation starters about differences in their memories.

With the rise of GPS tracking in various contexts such as smartphones and vehicles there has been a drastic increase in geospatial data being collect for personal reflection and organizational optimization. The generated movement datasets contain both geographical and temporal information, from which rich relational information can be derived. Common map visualizations perform especially well in revealing basic spatial patterns, but pay less attention to more nuanced relational properties. In contrast, network visualizations represent the specific topological structure of a dataset through the visual connections of nodes and their positioning. So far there has been relatively little research on combining these two approaches. Shifted Maps aims to bring maps and network visualizations together as equals. The visualization of places shown as circular map extracts and movements between places shown as edges, can be analyzed in different network arrangements, which reveal spatial and temporal topologies of movement data. We implemented a web-based prototype and report on challenges and opportunities about a novel network layout of places gathered during a qualitative evaluation.

Gemeint sind künstlerische Praktiken, die die Computertechnik zum Ausgangspunkt nehmen, um durch sie bedingte und über sie hinausgehende Fragestellungen ästhetisch neu zu verhandeln. Ausgangspunkt ist die postdigitale Beobachtung, dass Algorithmen und Daten die Gesellschaft längst durchziehen, unsere Verhältnisse zur sozialen und materiellen Welt zunehmend über digitale Repräsentationen vermitteln und die Komplexität ihrer technologischen Konstituierung unsichtbar wird (Bolter/Gruisin 1999; Cramer 2015; Berry/Dieter 2015; Contreras-Koterbay/Mirocha 2016). Vor diesem Hintergrund erlauben Kunstpraktiken, die mit digitalen Methoden generiert, aber nicht notwendigerweise digital vermittelt werden, in besonderem Maße Prozesse der Digitalisierung kritisch zu reflektieren und so die Beziehungen zwischen digitalen und physischen Räumen nicht aus dem Blick zu verlieren, sondern aktiv mitzugestalten. Dennoch finden sie in der Kulturellen Bildung (KuBi), deren Zielgruppen kaum Bewusstsein für das künstlerische und kritische Potenzial digitaler Formate haben, bislang wenig Berücksichtigung. Es scheint, als ob postdigitaler Kunst über die Altersgruppen hinweg ein hohes Maß an Affirmation von Digitalisierungsprozessen zugesprochen wird. Im Kontrast hierzu veranschaulichen prominente Vertreterinnen und Vertreter, wie digitale Methoden produktiv eingesetzt werden, um kritische Fragen zur Digitalisierung zu artikulieren (Bridle 2013). Hervorzuheben ist die Reflexionsfähigkeit medienimmanenter Ausdrucksformen postdigitaler Kunst, die eine rezeptive und kreative Auseinandersetzung mit ihrer soziotechnischen Spezifik ermöglicht, wenngleich sie im Kunstverständnis der jüngeren Generation kaum eine Rolle spielen (Meyer 2010, Seitz 2013a; Rat für Kulturelle Bildung 2015a). Es fehlt die notwendige Grundlagenforschung, um eine angemessene Anwendung postdigitalen Kunstschaffens für verschiedene Zielgruppen der KuBi zu ermöglichen. In dem folgenden Beitrag umreißen wir kurz den Status Quo der KuBi, reflektieren wesentliche Entwicklungslinien postdigitaler Kunst und formulieren Ansprüche für transdisziplinäre Forschung an deren Schnittmenge.
