In this video, we introduce a scenario with a prototype of camera-based context-aware smart object controller for a family in smart home. The smart object controller is a context-based user interface to exploit context of both user and environment. It uses context of user to personalize control interface. Environment context is used to discover services and used to check service conflict among users in smart home. It has a camera-based architecture that captures an image to recognize smart object and generates user interface. Through generated user interface, users can directly manipulate functions of various smart object and services as as universal controller. Furthermore it enhances handover of controllability between users to resolve service conflict in a multi-user scenario.
