Base on work we did together with DoCoMo Eurolabs in Munich we have published the article "Perci: Pervasive Service Interaction with the Internet of Things" in the IEEE Internet Computing special issue on the Internet of Things edited by Frédéric Thiesse and Florian Michahelles.
The paper discusses the linking of digital resources to the real world. We investigated how to augment everyday objects with RFID and Near Field Communication (NFC) tags to enable simpler ways for users to interact with service. We aim at creating a digital identities of real world objects and by this integrating them into the Internet of Things and associating them with digital information and services. In our experiments we explore how these objects can facilitate access to digital resources and support interaction with them-for example, through mobile devices that feature technologies for discovering, capturing, and using information from tagged objects.
