Taxonomy and Overview of Multi-touch Frameworks: Architecture, Scope and Features

Multi-touch hardware has only recently entered the mainstream of information technology. Interaction designers, product developers and users have been influenced by this development. In order to build multitouch applications, programmers have created various reusable frameworks. To obtain an overview of this diversity, we present a list of criteria to classify, evaluate, and select multi-touch frameworks. Our main contribution consists in a taxonomy that we have elaborated out of a vast list of existing projects, of which we present nine freely available ones here. To promote the development of multi-touch frameworks, our list of criteria reveals four main areas for future work.
