The aim of this work is to explore alternative interaction concepts for multi-focus visualizations in the context of single and multi-user scenarios. Alongside explicit interaction for navigating within multi-focus visualizations implicit interaction for making the visualization react on the social and spatial context is investigated.

One way to handle the representation of (and the navigation in) large datasets is by provisioning movable viewports – so-called dynamic peepholes. In my research I investigate how information spaces and the navigation with dynamic peepholes need to be designed in order to exploit spatial memory and navigation performance.

This work models the underlying interaction process with public interactive displays, and develops a laboratory-based experimental methodology that enables more rapid and controlled evaluation of potential interaction design strategies. Readers can benefit from gaining insights in designing and building better and more usable large interactive systems for public settings.

People commonly sketch externalizations on paper and whiteboards in their everyday thinking processes. My research aims to better understand these thinking sketches from the perspective of information visualization and pen-and-touch interaction and to apply this understanding to the design of interfaces that better support complex and freeform everyday thinking practices.

Natural interaction offers the user a great immersive experience and is easier to learn and utilize than classic human-computer interfaces. Our research aims to identify the problems during the design of 3D UIs and the interaction with virtual objects in 3D space, and find ways to solve or avoid those problems.

In my thesis I want to provide guidelines that help user interface designers to develop interaction \ techniques for multi-surface personal computing spaces that comprise both horizontal and vertical touchscreens and show potential benefits of a seamless connection between them (e.g. a curved display segment).
