Daniel Gröger is a PhD student in the Human-Computer Interaction group at Saarland University. He holds M.Sc. and B.Sc. degrees in Computer Science from Kaiserslautern University of Technology.
Daniel is interested in novel ways to interact with digital technologies embodied in our physical world. His research interests revolve around creating digital manufacturing technologies and leveraging their potential to explore and design expressive and more efficient novel human-computer interfaces.
Further research interests that he pursued during his prior studies include artificial intelligence and computer vision, in which he focused on leveraging optical eye-tracking methods to enhance performance of user interface technologies.

Projects

Tactlets
We present a novel digital fabrication approach for printing custom, high-resolution controls for electro-tactile output with integrated touch sensing on interactive objects. We call these controls Tactlets.

LASEC
LASEC enables instant do-it-yourself fabrication of circuits with custom stretchability. A new one-step laser ablation-and-cutting process creates circuitry and desired stretchability on a conventional laser cutter.

Tacttoo
Tacttoo is a feel-through interface for electro-tactile output on the user’s skin. At less than 35μm in thickness, it is the thinnest tactile interface for wearable computing to date.

ObjectSkin
ObjectSkin is a fabrication technique for adding conformal interactive surfaces to rigid and flexible everyday objects. It enables multi-touch sensing and display output that seamlessly integrates with highly curved and irregular geometries.

HotFlex
HotFlex leverages printed embedded elements, capable of computer-controlled state change, to enable hands-on remodeling, personalization, and customization of a 3D-printed object after it is printed.
