While touch sensing is commonplace for single points of contact, multi-touch systems enables a user to interact with a system with more than one finger at a time, allowing for the use of both hands along with chording gestures. These kinds of interactions hold tremendous potential for advances in efficiency, usability, and intuitiveness. Multi-touch systems are inherently also able to accommodate multiple users simultaneously, which is especially useful for collaborative scenarios such as interactive walls and tabletops.

We've developed a new multi-touch sensing technique that's unprecedented in precision and scalability, and I will be demonstrating some of our latest research on the new sorts of interaction techniques that are now possible.
