We present two designs in the area of the Internet of Things, utilizing the ontology-driven Smart Objects For Intelligent Applications (SOFIA) Interoperability Platform (IOP). The IOP connects domestic objects in the physical world to the information world, allowing for coaching the behaviour of, or raising awareness in, domestic energy consumption. The concept and architecture of the SOFIA IOP is introduced, in which the domestic objects are knowledge processors connected to a semantic information broker. This broker, using a blackboard design pattern, ontologies, and semantic web technologies, enables interoperability among both digital and physical entities. The two designs based on the SOFIA IOP are presented as examples for coaching with and learning from the Internet of Things. Although both designs are in the area of domestic energy consumption, they can be seen as good starting points towards broader areas of ubiquitous learning enabled by the Internet of Things.
