Ambient Intelligence
“Ambient Intelligence (AmI) is a vision of how
ICTs will shape our future. It depicts a world of
seamless intelligent environments, designed to
understand and adapt to the presence of people
and free them from manual control of their
surroundings“
(Gunnarsdóttir and Arribas-Ayllon, 2011)

Ambient Intelligence
1998
From Devices to ‘Ambient Intelligence’:
The Transformation of Consumer Electronics
(Zelkha and Epstein, 1998, Philips).
1999
The AmI vision drove the Europeans view on
electronics research, engineering and materials
sience.
2003
ISTAG, FP6

Ambient Intelligence
Now?
“We would expect to be witnessing the emergence of enduring principles and of
a growing body of research findings and solved challenges.
Instead, much of the research effort still seems to be devoted to the creation,
very often from scratch, of technologies and systems for enabling the scenarios
described in the AmI vision”
(José et al, 2010)

Ambient Intelligence started out as...
A technology integrator
6maarten.weyn@uantwerpen.be
Ambient Intelligence started out as...
• “The AmI vision was originally one of maximizing the potential of
consumer electronics, telecommunications, materials science and
computing, to support ‘people and objects to interact with their
environment in a seamless, trustworthy, and natural manner”
(Aarts and de Ruyter, 2009)
• Laid-back rather than lean-forward mode
• “Computing should ‘move from an explicit, instructional model to an
implicit, anticipatory one’ with context aware, personalized, adaptive and
anticipatory machine intelligence
(Gunnarsdóttir and Arribas-Ayllon, 2011)

Ambient Intelligence is moving
towards becoming...

ScenarioEllen returns home after a long day's work. At the front door she is recognized by an
intelligent surveillance camera, the door alarm is switched off, and the door unlocks and
opens. When she enters the hall the house map indicates that her husband Peter is at an
art fair in Paris, and that her daughter Charlotte is in the children's playroom, where she is
playing with an interactive screen. The remote children surveillance service is notified that
she is at home, and subsequently the on-line connection is switched off. When she enters
the kitchen the family memo frame lights up to indicate that there are new messages. The
shopping list that has been composed needs confirmation before it is sent to the
supermarket for delivery. There is also a message notifying that the home information
system has found new information on the semantic Web about economic holiday cottages
with sea sight in Spain. She briefly connects to the playroom to say hello to Charlotte, and
her video picture automatically appears on the flat screen that is currently used by
Charlotte. Next, she connects to Peter at the art fair in Paris. He shows her through his
contact lens camera some of the sculptures he intends to buy, and she confirms his choice.
In the mean time she selects one of the displayed menus that indicate what can be
prepared with the food that is currently available from the pantry and the refrigerator.
Next, she switches to the video on demand channel to watch the latest news program.
Through the 'follow me' she switches over to the flat screen in the bedroom where she is
going to have her personalized workout session. Later that evening, after Peter has
returned home, they are chatting with a friend in the living room with their personalized
ambient lighting switched on. They watch the virtual presenter that informs them about the
programs and the information that have been recorded by the home storage server earlier
that day.
