Multi-touch interaction requires a trade-off between users' desires and capabilities, and gesture recognition constraints. Current approaches to that problem lack flexibility. The number of fingers used for a gesture usually plays a key part in the recognition process, for example. In this paper, we propose the use of pseudo-rigid movements to increase the flexibility of this process. We show how these movements can be determined in real time from the contact information usually available. We explain how they allow to free the recognition process from the number of fingers used and to move towards multi movement gestures, independent or coordinated. Finally, we present an interaction technique that takes advantage of this increased flexibility.
