L'iBeacon, introduit lors de la WWDC en 2013 est en cours de standardisation, grâce au projet open-source Eddystone. Associé à cette technologie, le projet "The physical Web" lancé par Google, promet lui aussi de grandes innovations dans le monde de l'IoT. En effet, il a pour but de pouvoir relier un smartphone à un beacon sans passer par une application. Ceci offre un large panel d'utilisation, pour relier des lieux physiques avec le monde virtuel. Nous ferons le point sur le projet et les technologies sous-jacentes, avant de se plonger dans les cas d'utilisation concrets, existants ou à venir.

Foreword
The Era of Ubiquitous Computing

7. 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, 1991
The Computer for the Twenty-First Century

• “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

11. @bonbonking #xebiconfr
• 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.

Application developers should define a UUID specific to their
app and deployment use case.

Further 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.

101. @bonbonking #xebiconfr
• 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.
