Challenges in creating embedded ubiquitous services everywhere

In ubiquitous computing environment, many embedded computers, sensors, devices, and networks are connected for creating context-aware embedded ubiquitous services. We have been building smart rooms and smart furniture to develop such embedded ubiquitous applications. Since the smart furniture is equipped with embedded networked computers, sensors and various I/O devices, it can provide various services in a public or a private space. By simply placing the smart furniture in a space, we can instantaneously convert the legacy non-smart space into a smart space where location-based context-aware services, service roaming, personalized services and the connectivity to the Internet are provided.
