This Ph.D. project investigates novel interaction and visulization techniques for the creation, modification and exploration of graphs and node-link diagrams. One main aspect is the application of multitouch and pen input to edit diagrams on interactive displays. For that, a respective gesture set and graph layout tools were developed. Furthermore, visualization techniques such as off-screen visualizations are adopted to the domain of node-link diagrams. more information

Overall Projects
-
-
This project incorporates several subprojects that investigate the combination of different input modalities for more natural and efficient interaction especially with remote (distant) displays. For this purpose, we develop and evaluate several novel multimodal interaction techniques incorporating among others gaze input, hand gestures, mobile handhelds, and digital pen-and-paper. more information
-
This project explores novel interaction techniques that use spatially aware handheld displays (Tangible Magic Lenses) - usually within the environment of a larger stationary display such as an interactive tabletop. Besides the development of a technical basis (hard- and software framework), a vital scientific goal is the examination of the interplay between different interaction modalities. more information
-
This projects aims at developing effective visualization and interaction techniques for large diagrams and model visualizations. By means of filter strategies, detail and context techniques, and novel navigation support it should be possible to support decision processes in domains such as logistics and energy management. more information

ViERforES sub-project 10This project aims at developing natural and seamless interaction techniques in Mixed Reality environments. One focus are multiple-display scenarios, especially the usage of handheld magic lenses. Another goal is the development and evaluation of novel 3D interaction techniques using alternative modalities.
Current Individual Projects
-
We introduce Stackables: tangibles designed to support faceted information seeking in a variety of contexts. Each Stackable tangible represents search parameters that can be shared amongst collaborators, modified during an information seeking process, and stored and transferred. more information
-
Precise alignment of graphical objects and the creation of accurate layouts are crucial activities in many applications, such as graphics design tools, presentation software, or graph editors. Surface computing is very promising for these application domains but not fully explored yet. The aim of this project is to develop tools which support layout tasks on interactive displays. more information
-
Knowledge about what a user is currently concentrating on and is visually attending may improve the interaction particularly with large remote displays. Thus, this project is devoted to the investigation of possibilities to naturally integrate gaze data with additional input devices for a more efficient and effective use of digital systems. more information

This work targets the development of novel and natural 3D interaction techniques. For this purpose, different combinations of input and output modalities shall be investigated including the application of eye tracking for large displays. more information
-
Tangible Windows allow for performing common 3D interaction tasks in a more accessible manner by combining principles of tangible interaction, head-coupled perspective, and multitouch techniques. They either act as physical peepholes into a virtual 3D world or as physical containers for parts of that world. more information

To bring back the physical affordances of a painter’s palette to graphics editors, we propose to augment a tabletop with handheld displays. We introduce the concept of spatial Work Zones that take up distinct 3D regions above the table surface and serve as physical containers for digital content. This provides quick access to tools and parts of the graphics document that are instantly functional, i.e., ready to be used by a digital pen. more information
-
We contribute to the seamless integration of interaction and display devices and introduce novel ways of visualizing and directly interacting with information. Rather than restricting the interaction to the display surface alone, we explicitly use the physical three-dimensional space above it for natural interaction with multiple displays. more information
-
This project explores novel interaction techniques that are based on spatially aware tangible displays (Magic Lenses) in multi display environments. The height above a reference surface (e.g. tabletop) is used to better explore complex information spaces. more information
-
This project targets novel interaction and visualization techniques for graph structures. Thereby, the handling of node-link diagrams on interactive displays such as tabletops is one main focus. The navigation and visualization of software models shall serve as an example domain. more information
-
This project addresses the application of visualization techniques to the domain of diagrams. The aim is to make huge graph structures and software models more comprehensible and easier to navigate. more information

In this project, we aim at visualizing concepts of feature-oriented software development to support program comprehension. Specifically, we evaluate how the use of background colors can improve program comprehension. more information
Completed Individual Projects
-
This work targets the visualization of eye tracking data in three-dimensional virtual environments. 3D gaze paths, a model of interest timeline and several 3D attentional maps werde developed and integrated within the SVEETER tool. more information

This project focuses on the development of playful educational tabletop applications for the classroom of the future. For instance, such applications can be used to enrich teachers' lessons or introduce novel tabletop technologies to young students. more information

To provide intuitive ways of interacting with media data, this research addresses the seamless combination of sensor-enabled phones with large displays. An intuitive basic set of tilt, throw, and touch gestures is introduced for interacting with both mobile applications and distant user interfaces. more information

Future Personal Information and Media Management applications should support gaining an overview about a large collection, browsing, searching specific items, or filtering media objects. We developed basic zoomable UI techniques for faceted media browsing and applied them in sample applications. more information
