Supporting mobile service usage through physical mobile interaction
Although mobile services can be used ubiquitously, their employment and the interaction with them are still restricted by the constraints of mobile devices. In order to facilitate and leverage mobile interaction with services, we present a generic framework that combines semantic Web service technology and physical mobile interaction. This interaction paradigm uses mobile devices to extract information from augmented physical objects and use it for a more intuitive and convenient invocation of associated services. For that purpose, the presented framework exploits Web service descriptions for the automatic and dynamic generation of customizable user interfaces that support and facilitate physical mobile interaction. This generic approach to mobile interaction with services through the interaction with physical objects promises to meet the complementary development of the Internet of things. A user study with a prototype application for mobile ticketing confirms our concept and shows its limits.
