The objective of our work is to unify the virtual world of the computer with the physical world of the user into a single "Euclidean" space. We argue that this is the key to intuitive or “natural” user interfaces. 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.
