Mark Weiser is said to be the father of ubiquitous computing, he coined the term in the 80's. Wikipedia's page for Weiser lays out the principals he described in one of his talks:
1)the purpose of a computer is to help you do something else.
2)the best computer is a quiet invisable servant.
3)the more you can do by intuition the smarter you are; the computer should extend your unconscious.
4)technology should create calm.
He goes on to describe a reality where computers are tools used to achieve goals, and not the center of any real primary focus.
When this topic first came up in class i immediatly thought of the movie "Gamer". It stars Gerard Butler who plays 'Kable' a convict who is focred to play a deadly game against his will, primarily for public entertainment. It is set in the not too distant future, where ubiqquitous computing is the norm and is used by gamer prodigy 'Simon', the real life rich kid in the movie who pays to control Kable during the missions. Upon conviction, prisoners are given an RFID chip, which allows someone to tap in and control them. Simon plays this deadly game fromt the comfort of his own home, and whats more is he doesnt even have a controller, he just uses speech and movement to control all of his media, gaming, etc
Aside from the highly unethical issue with the improper treatment of inmates, this movie was REALLY cool. It would be totally amazing if, in our lifetime, middle to high class citizens could afford to use systems like these everyday. Nearly everything was wireless, and controlled through sensory movement. When Simon walks into his bedroom the radio system greets him and asks him what he'd like to do. He replies, log into Gamer, and BAM! projected on his wall, is the home page/site entrance for Gamer. It would be sooo cool if you could do that!! Eventually people wont even notice they're using computers anymore. Gamer is all thanks to Mark Weiser.
Other prominent ideas in this area include technology one can wear, thus having the ability to access it at any given moment. Some say in the future computers should be/will one day be worn much like glasses. Mark Weiser, said to be the father of ubiquitous computing said in an article he wrote to be published in CACM July 1993,
"the computer today is isolated and isolating from the overall situation, and fails to get out of the way of the work. In other words, rather than being a tool through which we work, and so which disapears from our awareness, the computer too often remains the focus of attention."
