Ubiquitous Computing by Utilizing Semantic Interoperability with Item-Level Object Identification

This paper presents a novel approach for utilizing item-level object identification in ubiquitous computing environment where the interaction between devices is based on semantic information interoperability. The paper also presents novel methods for human-machine interaction. In our approach we give a unique identifier for objects in the environment and combine the knowledge of the object identity with information from other sources by utilizing semantic information interoperability. The approach utilizes Smart-M3 interoperability solution for sharing semantic information between heterogeneous devices and RFID-technology for identifying physical objects in the environment. In order to demonstrate the use item-level tagging with semantic interoperability we have implemented a Smart Greenhouse demonstrator that consists of several smart devices and tagged objects.
