TY - THES A1 - Jun, Mi-Ran T1 - Das Prinzip des Faltens : Als grundlegende Software-Methapher für Benutzeroberflächen T1 - The principle of folding : As fundamental software methapher for user surfaces N2 - Das Prinzip des Faltens soll als Metapher für grafische Benutzeroberflächen weiterentwickelt werden. 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.

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.

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.

Visitors can collect paper cards representing the exhibits and put them on an interactive surface to display associated concepts and relations to other works. As a result, users can explore both the unifying themes of the exhibition as well as individual characteristics of exhibits. On basis of metadata schemata developed in the MACE (Metadata for Architectural Contents in Europe) project, the system has been put to use the Architecture Biennale to display the entries to the Everyville student competition.

T1 - Faceted Views of Varying Emphasis (FaVVEs) BT - a framework for visualising multi-perspective small multiples JF - Computer Graphics Forum N2 - Many datasets have multiple perspectives – for example space, time and description – and often analysts are required to study these multiple perspectives concurrently. This concurrent analysis becomes difficult when data are grouped and split into small multiples for comparison. A design challenge is thus to provide representations that enable multiple perspectives, split into small multiples, to be viewed simultaneously in ways that neither clutter nor overload. We present a design framework that allows us to do this. We claim that multi-perspective comparison across small multiples may be possible by superimposing perspectives on one another rather than juxtaposing those perspectives side-by-side. This approach defies conventional wisdom and likely results in visual and informational clutter. For this reason we propose designs at three levels of abstraction for each perspective. By flexibly varying the abstraction level, certain perspectives can be brought into, or out of, focus. We evaluate our framework through laboratory-style user tests. We find that superimposing, rather than juxtaposing, perspective views has little effect on performance of a low-level comparison task. We reflect on the user study and its design to further identify analysis situations for which our framework may be desirable. Although the user study findings were insufficiently discriminating, we believe our framework opens up a new design space for multi-perspective visual analysis.

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.

We developed an interactive visualization, which enables users to visually explore a geospatial network of actors. The multitouch tabletop, and the large size of the interactive surface invite users to explore the visualization in semi-public spaces. For a case study on scientific collaborations between institutions, we applied and improved several existing techniques for a walk-up-and-use system aimed at scientists for a social setting at a conference. We describe our iterative design approach, our two implemented prototypes, and the lessons learnt from their creation. We conducted user evaluation studies at the two on-location demonstrations, which provide evidence of the prototype usability and usefulness, and its support for understanding the distribution and connectivity in a geospatial network.
