We introduce the concept of a Visual Backchannel as a novel way of following and exploring online conversations about large-scale events. Microblogging communities, such as Twitter, are increasingly used as digital backchannels for timely exchange of brief comments and impressions during political speeches, sport competitions, natural disasters, and other(More)
We introduce the information flaneur as a new human-centred view on information seeking that is grounded in interdisciplinary research. We use the metaphor of the urban flaneur making sense of a city as an inspiring lens that brings together diverse perspectives. These perspectives shift information seeking towards a more optimistic outlook: the information(More)
We present PivotPaths, an interactive visualization for exploring faceted information resources. During both work and leisure, we increasingly interact with information spaces that contain multiple facets and relations, such as authors, keywords, and citations of academic publications, or actors and genres of movies. To navigate these interlinked resources(More)
Informal visualization in the form of sketching and diagramming has long been an established practise of professionals working in the fields of design, architecture, and engineering. Less is known, however, about the sketching and diagramming practices of computer scientists and software developers. Through a series of interviews with computer science(More)
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(More)
We propose a new way of navigating the Web using interactive information visualizations, and present encouraging results from a large-scale Web study of a visual exploration system. While the Web has become an immense, diverse information space, it has also evolved into a powerful software platform. We believe that the established interaction techniques of(More)
In common Web-based search interfaces, it can be difficult to formulate queries that simultaneously combine temporal, spatial, and topical data filters. We investigate how coordinated visualizations can enhance search and exploration of information on the World Wide Web by easing the formulation of these types of queries. Drawing from visual information(More)
In this work, we describe how EdgeMaps provide a new method for integrating the visualization of explicit and implicit data relations. Explicit relations are specific connections between entities already present in a given data set, while implicit relations are derived from mul-tidimensional data based on similarity measures. Many data sets include both(More)
In this paper we make the case for slowness in search. The main tenet of information seeking today is retrieving the right result rapidly. Developments such as instant search, question answering, and fact sheets strive to further this tendency towards acceleration. While there is value in quick lookups, the emphasis on immediacy not only limits the temporal(More)
We present Fluid Views, a web-based search environment designed to bridge overview and detail by integrating dynamic queries, semantic zooming, and dual layers. The most common form of search results is long ranked and paginated lists, which are seldom examined beyond the top ten items. To support more exploratory forms of information seeking, we bring(More)
