Location-Transparent User Interaction for Heterogenous Environments

Because of the rapid evolution of mobile and embedded computing devices, it is important for a business that its services are accessible for a large group of possible service consumers. These consumers want to gain access to the offered services from heterogeneous environments. In this context, much work has been done on the (semi-) automatic generation of user interfaces (UIs) for services that are mostly targeted toward mobile computing devices. However, most of that work fails to provide actual solutions to the problem of how to provide a suitable interaction mechanism between the generated UI and the application logic that implements the functionality. We will show that by defining the implementation of the application logic as a webservice, we can use webservice technologies to provide two-way communication between the application and its generated UI.
