1ForewordThe Era of Ubiquitous Computing
The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it.
—— Mark Weiser, Xerox Parc, 1991The Computer for the Twenty-First Century
Tabs: wearable centimetre sized devices
Pads: hand-held decimetre-sized devices
Boards: metre sized interactive display devices

• “The first era we call mainframe, each shared by lots of people. Now we are in the personal computing era, person and machine staring uneasily at each other across the desktop. Next comes ubiquitous computing, or the age of calm technology, when technology recedes into the background of our lives.”

The Major Trends in Computing
Mainframe many people share a computer
Personal Computer one computer, one person
Internet - Widespread Distributed Computing
Ubiquitous Computing many computers share each of us

• Context awareness originated as a term from ubiquitous computing or as so-called pervasive computing which sought to deal with linking changes in the environment with computer systems, which are otherwise static.

UUID 16 bytes Application developers should define a UUID specific to their app and deployment use case.
Major 2 bytesFurther specifies a specific iBeacon and use case. For example, this could define a sub-region within a larger region defined by the UUID.
Minor 2 bytes Allows further subdivision of region or use case, specified by the application developer.

• The purpose of a computer is to help you do something else.
• The best computer is a quiet, invisible servant.
• The more you can do by intuition the smarter you are; the computer should extend your unconscious.
• Technology should create calm.
—— Mark Weiser and John Seely Brown, Xerox Parc, 1996The Coming Age of Calm Technology
