An Extensible Architecture for Multitouch & Pen Interactive Tables

Augmented multitouch interaction provides a better user experience, but requires the integration of other input sources, e.g., a digital pen, each featuring an own API. Our approach to a multitouch table is realized as a service-oriented architecture combining these different aspects under the hood of a common API. Their use make our table work with a variety of input devices and offer the opportunity of extending the capabilities by adding new services.
