Abstract: In recent years, with the development of the multi-touch technology, there has been a large number of available multi-touch interface software. But the characteristic of this phenomenon is that there is not a large extent similar in different softwares, but not much interoperability. In order to improve the interoperability and compatibility of different software, this paper extracts the common features of them, according to features of these software systems, and proposes a layered software architecture. The architecture defines a common interface between different levels, and for developers to shield the different types of hardware platforms, provides a unified view.

Key words: multi-touch, framework, architecture
