TL;DR: Faceted browsing is a promising way to incrementally refine data sets but approaches do not scale well in terms of screen size and have shortcomings in interacting with hierarchical facets, so FacetZoom is introduced, a novel multi-scale widget combining facet browsing with zoomable user interfaces.
Abstract: Faceted browsing is a promising way to incrementally refine data sets. Current approaches do not scale well in terms of screen size and have shortcomings in interacting with hierarchical facets. This paper introduces FacetZoom, a novel multi-scale widget combining facet browsing with zoomable user interfaces. Hierarchical facets are displayed as space-filling widgets which allow a fast traversal across all levels while simultaneously maintaining context. We contribute both a seamless continuous navigation and a quick tap-and-center interaction. Two prototypes are described which successfully apply the space-structuring widget to continuous, sampled data and an information collection. A formative user study of the latter indicates that the interface scales well to small screens. FacetZoom is versatile and offers consistent searching and browsing behaviors in a multitude of applications and device settings.

TL;DR: This work addresses the seamless combination of sensor-enabled phones with large displays with an intuitive basic set of tilt gestures introduced for a stepwise or continuous interaction with both mobile applications and distant user interfaces by utilizing the handheld as a remote control.
Abstract: To overcome limitations of small screens and to provide intuitive ways of interacting with personal data, this work addresses the seamless combination of sensor-enabled phones with large displays. An intuitive basic set of tilt gestures is introduced for a stepwise or continuous interaction with both mobile applications and distant user interfaces by utilizing the handheld as a remote control. In addition, we introduce throwing gestures to transfer media documents to a large display. By means of these gestures, we also propose transferring a running interface from a mobile phone to a large screen (to improve usability) and back (to achieve mobility). We demonstrate the feasibility of the interaction methods with several application prototypes facilitating a very natural flow of interaction.

TL;DR: This work addresses problems of complex UML diagrams and proposes the usage of semantic zooming with different levels of detail and describes intuitive interaction techniques to ease the navigation between different diagrams in software models.
Abstract: Models become increasingly important for software development processes. Though there is a multitude of software modeling tools available, the handling of complex UML diagrams is still difficult. In particular, the visualization of a global overview and of logical interrelationships between certain elements arising from refinements of diagrams can be improved. We address these problems and propose the usage of semantic zooming with different levels of detail and describe intuitive interaction techniques to ease the navigation between different diagrams in software models.

TL;DR: Facet Folders are a visualization and interaction concept for filtering collections of personal data that explicitly expose the faceted metadata used for filtering, enabling the construction of dynamically updating views across multiple facets.
Abstract: Facet Folders are a visualization and interaction concept for filtering collections of personal data. Although visually derived from the ubiquitous folder hierarchies of file managers, Facet Folders explicitly expose the faceted metadata used for filtering. Facet Folders can be arranged into persistent hierarchies, enabling the construction of dynamically updating views across multiple facets. If demands change, the hierarchy can be easily rearranged.

TL;DR: This paper deals with work in progress concerning the seamless integration of paper-based and digital UML-sketching, which includes special UML sketch books and paper palettes used in combination with tabletops.
Abstract: Drawing diagrams is one of the most important activities during software development processes. A multitude of sketch-based diagram tools were developed to enhance sketching with digital features. However, these applications are not as flexible as paper and often obstruct spontaneous sketching. To overcome these drawbacks we suggest the usage of digital pens and paper in conjunction with sketch-based UML diagram tools. This paper deals with work in progress concerning the seamless integration of paper-based and digital UML-sketching. Amongst others, this includes special UML sketch books and paper palettes used in combination with tabletops.
