Tangible Awareness: How Tangibles on Tabletops Influence Awareness of Each Other’s Actions

Knobology Revisited: A Comparison of User Performance between Tangible and Virtual Rotary Knobs

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.

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.

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.

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.

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.

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.

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.

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.

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.

Dynamic Portals is a light-weight touch-based technique that allows to transfer virtual objects to distant locations on an interactive tabletop.

Hybrid documents ease text corpus analysis for literary scholars. Co-locating physical and digital media in one surface combines their advantages.

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.

We are developing an HCI design pattern language that provides solutions for recurring problems when designing interactive tabletops and applications.

Mudpad is a multitouch screen that is enhanced with localized active haptic feedback.

SLAP Widgets are tangible general-purpose controls for interactive tabletops, made from silicone and acrylic. They combine the haptic feedback of physical controls with the flexibility of on-screen widgets.

Chronicler: Interactive Exploration of Source Code History

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.

DRAGON is a direct-manipulation interaction technique for frame-accurate navigation in video scenes.
