Ubiquitous computing

"Ubiquitous computing involves having computing devices essentially everywherein the home, office or public area, as well as easy, natural ways for people to interact with them. Wireless technologies, sensors, radio frequency identification (RFID) tags and machine-to-machine communications will play a big role in this new area of computing."
