What is "touchtoolkit"

TouchToolkit is a software development kit to simplify the complexities of multi-touch application development and testing. The framework currently supports WPF 4.0 and Silverlight 4.0. The key features of TouchToolkit are:

• A domain-specific language to define new gestures including multi-user, multi-touch scenarios.
• A device independent architecture that allows the application to run on different devices without any change in application code.
• A test framework that allows to write unit tests to validate touch interactions and gesture definitions.
• A record/playback tool for simulating multi-user scenarios as well as testing & debugging applications
