Notes:


The Web exhibits spontaneous interaction: I can buy books from Amazon.com without downloading and installing a book buying application. However, neither client nor server are connected to physical objects. Robotic manufacturing exhibits physical virtual connections, but the application is fixed not spontaneous. Ubicomp needs both spontaneity and physical connection. Nomadic computing is a form of Ubicomp. Its beyond mobile computing that we do with 802.11 cards in our laptops, but it is not so far out as to be impossible to implement with today’s technology.
