Ubiquitous Computing

I learned that Ubiquitous computing is a vision of where computers are headed. The writer who speaks of ubiquitous computing as something we don't even think about its just a part of our everyday life. Some examples he gave were things like when we turn on our lights its operated by computer when walk in a room wireless communication would turn our lights on and if we touched an appliance it would turn on, etc... I don't think we are there yet but I do believe we are heading in that direction. Some peoples homes and environments are not anywhere near that type of environment. I can see this happening in some of the newer homes being built. An example would be the whole deal with energy efficient devices. Rochelle
