Abstract – Plug-and-play is an important mechanism for achieving component integration and improving interoperability in smart transducer systems. While recent research in smart transducer interfaces has achieved a syntactically well-defined interface to arbitrary sensors and actuators, current plug-andplay approaches are limited by the semantic gap between the control application and the generic smart transducers. In this paper we propose a solution to this problem by establishing a smart interface system that consumes the sensor data from the smart transducers and provides a syntactically and semantically standardized interface to the control application. The smart interface system will be configured using data from the transducer meta-description, a system metadescription and the requirements from generic sensor data processing. As case study for such an interface system we present a generic high-level application component in form of the generic certainty grid, a sensor fusion ...
