The late Mark Weiser (head of the Computer Science Lab at Xerox PARC) described and pioneered that dream, which he called Ubiquitous Computing:

Ubiquitous Computing Demonstration using Tabs, Pads and Boards from 1988

>Specialized elements of hardware and software, connected by wires, radio waves and infrared, will be so ubiquitous that no one will notice their presence.

>The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it.

Tabs, Pads, and Boards

>In the post-PC era, we are getting closer to the vision of ubiquitous computing, a termed coined by Mark Weiser in 1988 (a chief scientist at Xerox PARC in the U.S.). Simply put, computing would be on any device, in any location, and in any format.

>We're getting there. During my son's homework this week we created a Word document on an iPad, inserted a photo taken on a Windows phone, saved the doc to the cloud via Dropbox, printed the doc from a laptop over wifi to a printer.

>Weiser helpfully proposed three basic forms for ubiquitous system devices;

>Tabs: wearable centimetre sized devices

>Pads: hand-held decimetre-sized devices

>Boards: metre sized interactive display devices

>Ubiquitous computing (or "ubicomp") is a concept in software engineering and computer science where computing is made to appear anytime and everywhere. In contrast to desktop computing, ubiquitous computing can occur using any device, in any location, and in any format. A user interacts with the computer, which can exist in many different forms, including laptop computers, tablets and terminals in everyday objects such as a refrigerator or a pair of glasses. The underlying technologies to support ubiquitous computing include Internet, advanced middleware, operating system, mobile code, sensors, microprocessors, new I/O and user interfaces, computer networks, mobile protocols, location and positioning, and new materials.
