A $1,000 PC is now approximately equal to the computational ability of the human brain.
Computers are now largely invisible and are embedded everywhereñin walls, tables, chairs, desks, clothing, jewelry, and bodies.
3-D virtual reality displays, embedded in glasses and contact lenses, as well as auditory ìlensesî, are used routinely as primary interfaces for communication with other persons, computers, the Web, and virtual reality.
Most interaction with computing is through gestures and two-way natural-language spoken communication.
