Smart memo service design for augmented smart space

In this paper, we present our approach for developing a smart space environment. The system is fundamentally designed for adaptive information augmentation within a physical space with a projector and depth cameras, and various technologies are converged including spatial relations and contextual semantic knowledge management, user tracking and facial recognition, etc. The system design is focused on the smart memo service scenario, where messages bound to certain people or objects can be displayed on nearby surfaces.
