When building enterprise applications that need to be accessed through a variety of client devices, developers usually strive to implement most of the business logic deviceindependently while using a web browser to display the user interface. However, when those web-based front-ends shall be rendered on different devices, their differing I/O capabilities may require device-specific interaction patterns that still need to be specified and implemented efficiently. We present an approach for specifying the dialog flows in multichannel web interfaces with very low redundancy and introduce a framework that controls web interfaces? devicespecific dialog flows according to those specifications, while keeping the enterprise application logic completely deviceindependent.
