Our research focuses on innovative ways of seamlessly integrating digital media with the effective, expressive and engaging ways people interact in the physical world. Our goal is to make objects responsive, render surfaces and spaces interactive, and augment the human itself. To do so, we leverage cutting-edge technology, such as printed electronics, interactive paper, flexible and multiple displays. This yields novel interaction possibilities for which we design, implement and study user interfaces and interactive systems.
