Research on smart environments represents some of the most innovative work being done in computer science, electrical engineering, and information systems today. The interdisciplinary scope of the field integrates aspects of machine learning, human machine interfacing, wireless networking, mobile communications, sensor networks and pervasive computing. Unprecedented new possibilities come into existence. The development of a seamless environment that is constantly aware of the presence of people, their needs and desires and that is capable of intelligently responding via intuitive and natural user interfaces such as gestures, speech, etc. is a matter of time. The role of electrical engineers and computer scientists in these developments is eminent.
