Headed by Prof. Dr. Jan Borchers, we work in Human-Computer Interaction (HCI). Grounded in Computer Science, we develop and study new interaction theories, techniques, and systems in personal digital fabrication and personal design, tangible, mobile, and wearable user interfaces, interactive textiles, multitouch tables and interactive surfaces, augmented reality, and visual coding environments. Our goal is to make the Brave New World of interactive technologies useful by making it usable.
Check out the current overview of our research projects below, or see our older Research Overview for a more detailed text.

Tabletops and Tangibles
Tangible Awareness: How Tangibles on Tabletops Influence Awareness of Each Other’s Actions
Paper at CHI 2018
Knobology Revisited: A Comparison of User Performance between Tangible and Virtual Rotary Knobs
Note at ITS 2015
PERCs: Persistently Trackable Tangibles on Capacitive Multi-Touch Displaysuse the touch probing signal from capacitive touch screens to determine whether the tangibles are on- or off-screen.
Paper at UIST 2015
Indirect Touch is a multitouch system in which users indirectly manipulate objects on the vertical screen by with touches on the horizontal screen to improve ergonomics.
Paper at CHI 2013
Passive Untouched Capacitive Widgets (PUCs) are simple physical widgets the can be detected by an unmodified capacitive touch screen without being touched by a user.
Note at ITS 2013
Touch interfaces provide great flexibility in designing a UI. However, the actual experience is often frustrating due to bad touch recognition. We showed that with only minimal preparation the touch accuracy of standard hardware can be improved allowing better recognition rates.
Note at CHI 2013
Instant User Interfaces enable users to repurpose everyday objects as input devices in an ad-hoc manner by using a reliable, marker-free object tracking system that enables users to assign semantic meaning to different poses or touches in different areas.
HoloDesk is a novel interactive system combining an optical see through display and Kinect camera to create the illusion that users are directly interacting with 3D graphics.
Paper at CHI 2012
BendDesk is an interactive desk environment that merges a vertical and a horizontal display with a curve. The entire surface is touch sensitive and supports direct manipulation of digital objects.
Paper at ITS 2010
3D Displays can be controlled using direct manipulation. This, however, introduces problems as the direct notion means that our object should stick to our fingers during interaction. We compared different methods to cope with the constraints of these interactions.
Paper at ITS 2012
We render physical effects in tabletop controls using electromagnetic actuation. Keeping the advantages of low-cost passive tangible, we allow designers to change physical properties on the fly, such as weight, friction, spring resistance, and detents.
Note at CHI 2011
FingerFlux is a haptic output technique that provides near-surface haptic feedback on interactive tabletops. It combines an electromagnetic display with a permanent magnet attached to the user’s index finger.
Paper at UIST 2011
Dynamic Portals is a light-weight touch-based technique that allows to transfer virtual objects to distant locations on an interactive tabletop.
Note at ITS 2011
Hybrid documents ease text corpus analysis for literary scholars. Co-locating physical and digital media in one surface combines their advantages.
Paper at ITS 2010
Madgets are low-cost, untethered, and easy-to-build tangible controls for interactive tabletops. Our tabletop maintains the consistency between physical controls and their digital state by using electromagnetic actuation.
Paper at UIST 2010
We are developing an HCI design pattern language that provides solutions for recurring problems when designing interactive tabletops and applications.
Paper at EuroPLoP 2010
Mudpad is a multitouch screen that is enhanced with localized active haptic feedback.
Note at ITS 2010
Navigation and Exploration Interfaces
Vesta implements the idea to leverage runtime information from manual executions performed by developers to support authoring of documentation and unit tests.
Statsplorer is a software tool that allows users to do statistical analysis by interacting with visualizations.
Live coding environments provide information about a program’s execution immediately after each change to the source code.
We suggest a method to analyse developers' Navigation Strategies using predictive models and apply this method to compare different call graph navigation tools.
Stacksplorer provides a novel way to visualize potential call stacks within a traditional IDE and allows navigation along these call stacks.
Fly is a novel Presentation Tool that breaks with the Slide Metaphor and assembles Information Landscapes on a 2D Plane.
