In recent years, a large amount of software for multitouch in- terfaces with various degrees of similarity has been written. In order to improve interoperability, we aim to identify the common traits of these systems and present a layered soft- ware architecture which abstracts these similarities by defin- ing common interfaces between these layers. This provides developers with a unified view of the various types of mul- titouch hardware. Moreover, the layered architecture allows easy integration of existing software as well as swapping of components. Finally, we present our implementation of this architecture, consisting of hardware abstraction, calibration, event interpretation and widget layers.     «
