Most of our research takes on an engineering perspective. We create new types of mobile devices, touch devices and interactive floors, and gesture input devices. In addition, we are trying to gain a deeper understanding of touch input through scientific experiments. Check out our current research projects.

Mission

The most popular computers world-wide are not computers—they are mobile phones. Four billion phones give us access to the digital world anytime. And arguably even more important, mobile phones give access to the digital world to billions of users who have never even seen a PC. Mobile phones have thereby made the idea of a “$100 computer” reality—even though different from how many of us had expected.

But the new, unexpected computing platform for the masses brings up many new questions. How to interact with these tiny devices? How to display the expansive data sets many of our tasks require and how to edit them? Is it possible to “think” with these tiny devices—even as well as we do using PCs?

To answer these questions is the mission of this group, the human computer interaction lab at Hasso Plattner Institute (ranked #1 in the nation-wide among computer science departments according to "CHE-Hochschulranking")
