Emosaic is grounded in psychological research on the relationship between language, affect, and color perception. We capitalize on an established three-dimensional model of human emotion: valence (good, nice vs. bad, awful), arousal (calm, passive vs. exciting, active) and dominance (weak, controlled vs. strong, in control). Previously, multi-dimensional models of emotion have been used rarely in visualizations of textual data, due to the perceptual challenges involved. Furthermore, until recently most text visualizations remained at a high level, precluding closer engagement with the deep semantic content of the text. Informed by empirical studies, we introduce a color mapping that translates any point in three-dimensional affective space into a unique color. Emosaic uses affective dictionaries of words annotated with the three emotional parameters of the valence-arousal-dominance model to extract emotional meanings from texts and then assigns to them corresponding color parameters of the hue-saturation-brightness color space. This approach of mapping emotion to color is aimed at helping readers to more easily grasp the emotional tone of the text. Several features of Emosaic allow readers to interactively explore the affective content of the text in more detail; e.g., in aggregated form as histograms, in sequential form following the order of text, and in detail embedded into the text display itself. Interaction techniques have been included to allow for filtering and navigating of text and visualizations.

Visualization as a tool for analysis, exploration, and communication has become a driving force in the task of unravelling our complex urban fabrics. This paper outlines the findings from a series of three workshops from 2018-2020 bringing together experts in urban data visualization with the aim of exploring multidisciplinary perspectives from the human-centric lens. Based on the rich and detailed workshop discussions identifying challenges and opportunities for urban data visualization research, we outline major human-centric themes and considerations fundamental for CityVis design and introduce a framework for an urban visualization design space.

Es soll untersucht werden, ob das Erlernen und das Verständnis der Bedienung bestimmter Programmfunktionen im Wesentlichen durch Faltprinzipien erleichtert werden. Eine Vielzahl von Funktionen wird heute in einem einzigen Gerät integriert. Die so entstehenden Hybriden stellen aus Sicht des Designs jedoch die Frage nach Form und Gestalt des Artefakts. Wegen der kleinen Größe der mobilen Geräte ist es folglich problematisch all diese unterschiedlichen Interfaces auf der Benutzeroberfläche zu integrieren. Versucht man diese unterschiedlichen Interfaces zu vereinen, ist das Ergebnis ein unübersichtliches, verwirrendes Interface mit eingeschränkter Bedienung. Zudem findet das Interface für die obsolete Desktop-Metapher immer noch Verwendung. Durch den bezug zu real existierenden Arbeitsumgebungen sind Desktop-Systeme zwar einfach zu bedienen und verständlich, doch können sie nicht ausgebaut werden. Problematisch ist vor allem die kleine Größe der Desktops, um die Desktop-Metapher konvenabel auszuführen. Demnach ist eine konvenable Bedienung aufgrund der veralteten Desktop-Metapher sowie des Interfaces hinsichtlich der Miniaturisierung der mobilen Geräte nur eingeschränkt möglich oder sogar undurchführbar. Die Arbeit erhebt hiernach den Anspruch, Überlegungen anzustreben, die den Begriff ‚Interface’ neu definieren sowie die daraus resultierende These „Das Paradigma ‚Falten‘ ist die Zukunft der ‚ePaper-Technologie‘ zu diskutieren.

There has been considerable research on collaborative sensemaking with visualizations and the personal relation of people with data. Yet, little is known about how public audiences without specific expertise and shared incentives openly express their thoughts, feelings, and insights in response to data visualizations. Motivated by the extensive social exchange around visualizations in online communities, this research examines characteristics and motivations of people’s reactions to posts featuring visualizations. Following a Grounded Theory approach, we study 475 reactions from the /r/dataisbeautiful community, identify ten distinguishable reaction types, and consider their contribution to the discourse. A follow-up survey with 168 Reddit users clarified their intentions to react. Our results help understand the role of personal perspectives on data and inform future interfaces that integrate audience reactions into visualizations to foster a public discourse about data.

The mapping of large spatial data sets is not only of interest for experts anymore, but, with regard to the latest advances in web cartography, also moves into the domain of public cartographic applications. One interactive web-based cartographic interface design pattern that helps with visualizing and interacting with large, high density data sets is the marker cluster; a functionality already in use in many web-based products and solutions. In this article, the author will present their ongoing research on the problem of “too many markers.” They will present an empirical evaluation and comparison of marker cluster techniques and similar approaches, including heatmaps and tiled heatmaps. They conclude with a first concept for overcoming some of the obstacles that they were able to identify in their study and thereby introduce a new direction for further research.

The HeatTile system (Meier et al. 2014) is used and extended with a progressive loading approach, the stream approach. By combining those two approaches, this study aimed to overcome the performance and bandwidth limitations inherent to mobile devices. This chapter focuses on the technological advantages of the presented approach in a performance comparison with other common approaches. Furthermore, an animated time series visualization is introduced, as well as an interface designed specifically for the presented method in order to emphasize the advantages of the approach. To further highlight the possible applications of the method, two real-world use cases are presented.

While there is a broad range of research projects that focus on developing new methods, techniques, and implementations, empirical analysis of the potential implications of this trend is still rare. In this paper, the potential influence of visualizations in online journalism is in the focus: perceived credibility. The need for such empirical research is emphasized by presenting a preliminary quantitative study that assesses the impact of maps and information visualization on the perceived credibility of online news articles.
