3. Introduction(1/2) 3 Smart devices, such as smart phone & tablet PC, are being widely introduced to users –equipped with mobile operating system such as IOS, Android, Windows 8 –act as a service platform of various applications Smart devices are recently emerging as a main control device of home services –to monitor & control home devices at home and out of home –replace the traditional fixed on the wall

8. Scope Addresses the application interoperability model based on ISO/IEC 18012-2 between the smart device and the HES for home control services. –ISO/IEC 18012-2 addresses basic taxonomy and application model aspects related to the operational mode of interoperable HESs. Defines the application objects needed to support the service, and describes the generic interface between those objects. –The use cases of the generally available home control service with smart devices are listed. –To support those use cases, events and their flows for command, status report or data, which are exchanged between the application objects of the application interoperability model, are defined. 8
