Seminar Report on Ambient Intelligence

1. 1
ABSTRACT
Ambient intelligence is an emerging discipline that brings intelligence to our everyday
environments and makes those environments sensitive to us. Ambient intelligence (AmI)
research builds upon advances in sensors and sensor networks, pervasive computing, and
artificial intelligence. Because these contributing fields have experienced tremendous growth in
the last few years, AmI research has strengthened and expanded. Because AmI research is
maturing, the resulting technologies promise to revolutionarize daily human life by making
people's surroundings edible and adaptive.
Ambient Intelligence (AmI) refers to a vision of the future information society where intelligent
interfaces enable people and devices to interact with each other and with the environment.
Today, most of the technologies needed for the realization of this vision are next-generation
technologies that are not currently on the market, but are being researched by research institutes
and corporate laboratories worldwide. In Europe, the IST Advisory Group (ISTAG) and the FP6
IST programme are strong promoters of the AmI vision. This article gives a short overview of
AmI, focuses on its role in everyday life and identifies some of the major challenges and
bottlenecks facing the concept. The paper argues that, although people are presented as at the
core of the vision, AmI would benefit from a more substantial everyday life perspective that
confronts users in their everyday lives with future visions and technologies.

INTRODUCTION
Ambient intelligence (AmI) refers to electronic environments that are sensitive and responsive to
the presence of people. Ambient intelligence is a vision on the future of consumer electronics,
telecommunications and computing that was originally developed in the late 1990s for the time
frame 2010–2020. In an ambient intelligence world, devices work in concert to support people in
carrying out their everyday life activities, tasks and rituals in an easy, natural way using
information and intelligence that is hidden in the network connecting these devices (see Internet
of Things). As these devices grow smaller, more connected and more integrated into our
environment, the technology disappears into our surroundings until only the user interface
remains perceivable by users.
The ambient intelligence paradigm builds upon pervasive computing, ubiquitous computing,
profiling, context awareness, and human-centric computer interaction design and is characterized
by systems and technologies that are:
 embedded: many networked devices are integrated into the environment
 context aware: these devices can recognize you and your situational context
 personalized: they can be tailored to your needs
 adaptive: they can change in response to you
 anticipatory: they can anticipate your desires without conscious mediation.
AmI refers to a digital environment that proactively, but sensibly, supports people in their
everyday lives. It will make the feeling that the people live with technology. It is aligned with the
concept of ‘disappearing computer’, since the AmI environment make the technology invisible.
As the devices grow smaller, more connected and more integrated into our environment, the
technology disappears into our surroundings. “The most profound technologies are those that
disappear. They weave themselves into the fabric of everyday life until they are indistinguishable
from it.” M. Weiser The basic idea behind AmI is that by enriching an environment with
technology (mainly sensors and devices interconnected through a network), a system can be built
to take decisions to benefit the users of that environment based on real-time information gathered
and historical data accumulated.

An important aspect of AmI has to do with interaction. On one side there is a motivation to
reduce the human-computer interaction as the system is supposed to use its intelligence to infer
situations and user needs from the recorded activities, as if a passive human assistant was
observing activities unfold with the expectation to help when (and only if) required. On the other
side, a diversity of users may need or voluntarily seek direct interaction with the system to
indicate preferences and needs. The entire environment around us, homes and offices, cars and
cities, will collectively develop a pervasive network of intelligent devices that will cooperatively
gather, process and transport information.
Ambient intelligence is closely related to the long term vision of an intelligent service system in
which technologies are able to automate a platform embedding the required devices for powering
context aware, personalized, adaptive and anticipatory services. Where in other media
environment the interface is clearly distinct, in an ubiquitous environment 'content' differs. Artur
Lugmayr defined such a smart environment by describing it as ambient media. It is constituted of
the communication of information in ubiquitous and pervasive environments. The concept of
ambient media relates to ambient media form, ambient media content, and ambient media
technology. Its principles have been established by Artur Lugmayr and are manifestation,
morphing, intelligence, and experience. A typical context of ambient intelligence environment is
a Home environment.
Ambient Intelligence is based on the key technologies: Ubiquitous Computing, Ubiquitous
Communication and Intelligent User Interface.
 Ubiquitous Computing means the integration of microprocessors into everyday objects
like furniture, clothes or toys.
 Ubiquitous Communication should enable these objects to communicate with each other
and with the user.
 Intelligent User Interface enables the inhabitants of the AmI to control and interact with
the environment in a natural (voice, gestures) and personalized way (preferences,
context).

HISTORY
In 1998, the board of management of Philips commissioned a series of presentations and internal
workshops, organized by Eli Zelkha and Brian Epstein of Palo Alto Ventures (who, with Simon
Birrell, coined the name 'Ambient Intelligence') to investigate different scenarios that would
transform the high-volume consumer electronic industry from the current “fragmented with
features” world into a world in 2020 where user-friendly devices support ubiquitous information,
communication and entertainment. While developing the Ambient Intelligence concept, Palo
Alto Ventures created the keynote address for Roel Pieper of Philips for the Digital Living Room
Conference, 1998. The group included Eli Zelkha, Brian Epstein, Simon Birrell, Doug Randall,
and Clark Dodsworth. In the years after, these developments grew more mature. In 1999, Philips
joined the Oxygen alliance, an international consortium of industrial partners within the context
of the MIT Oxygen project, aimed at developing technology for the computer of the 21st
century. In 2000, plans were made to construct a feasibility and usability facility dedicated to
Ambient Intelligence. This HomeLab officially opened on 24 April 2002.

Along with the development of the vision at Philips, a number of parallel initiatives started to
explore ambient intelligence in more detail. Following the advice of the Information Society and
Technology Advisory Group (ISTAG), the European Commission used the vision for the launch
of their sixth framework (FP6) in Information, Society and Technology (IST), with a subsidiary

6. 6
budget of 3.7 billion euros. The European Commission played a crucial role in the further
development of the AmI vision. As a result of many initiatives the AmI vision gained traction.
During the past few years several major initiatives have been started. Fraunhofer Society started
several activities in a variety of domains including multimedia, microsystems design and
augmented spaces. MIT started an Ambient Intelligence research group at their Media Lab.
Several more research projects started in a variety of countries such as USA, Canada, Spain,
France and the Netherlands. In 2004, the first European symposium on Ambient Intelligence
(EUSAI) was held and many other conferences have been held that address special topics in
AmI.

TECHNOLOGY USED
Ambient Intelligence is based on the three key technologies:-
 Ubiquitous Computing
Ubiquitous computing is a concept in software engineering and computer science where
computing is made to appear everywhere and anywhere. 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 fridge 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, networks,
mobile protocols, location and positioning and new materials.
 Ubiquitous Communication
Ubiquitous Communication enables these objects to communicate with each other and the user
by means of ad-hoc and wireless networking.
 Intelligent User Interface
An intelligent user interface (Intelligent IU, IUI, or sometimes Interface Agent) is a user
interface (UI) that involves some aspect of Artificial Intelligence (AI or Computational
Intelligence). There are many modern examples of IUIs, the most famous (or infamous) being
the Microsoft Office Assistant, whose most recognizable agentive representation was called
"Clippy".
Generally, an IUI involves the computer-side having sophisticated knowledge of the domain
and/or a model of the user. These allow the interface to better understand the user's needs and
personalize or guide the interaction.

8. 8
A variety of technologies can be used to enable Ambient intelligence environments such as:-
 Bluetooth Low Energy
Bluetooth low energy or Bluetooth LE, marketed as Bluetooth Smart, is a wireless personal area
network technology designed and marketed by the Bluetooth Special Interest Group aimed at
novel applications in the healthcare, fitness, beacons, security, and home entertainment
industries. Compared to Classic Bluetooth, Bluetooth Smart is intended to provide considerably
reduced power consumption and cost while maintaining a similar communication range.
 Radio Frequency Identification:
Radio-frequency identification (RFID) is the use of a wireless non-contact system that uses
radio-frequency electromagnetic fields to transfer data from a tag attached to an object, for the
purposes of automatic identification and tracking. Some tags require no battery and are powered
by the electromagnetic fields used to read them. Others use a local power source and emit radio
waves (electromagnetic radiation at radio frequencies). The tag contains electronically stored
information which can be read from up to several meters (yards) away. Unlike a bar code, the tag
does not need to be within line of sight of the reader and may be embedded in the tracked object.
 Microchip implant (human):
A human microchip implant is an integrated circuit device or RFID transponder encased in
silicate glass and implanted in the body of a human being. A subdermal implant typically
contains a unique ID number that can be linked to information contained in an external database,
such as personal identification, medical history, medications, allergies, and contact information.
 Sensor:
A sensor (also called detector) is a converter that measures a physical quantity and converts it
into a signal which can be read by an observer or by an (today mostly electronic) instrument. For
example, a mercury-in-glass thermometer converts the measured temperature into expansion and
contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts
temperature to an output voltage which can be read by a voltmeter. For accuracy, most sensors
are calibrated against known standards.

9. 9
Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and
lamps which dim or brighten by touching the base. There are also innumerable applications for
sensors of which most people are never aware.
 Software Agent:
Software agent is a software program that acts for a user or other program in a relationship of
agency, which derives from the Latin agere (to do): an agreement to act on one's behalf. Such
"action on behalf of" implies the authority to decide which, if any, action is appropriate.
Related and derived concepts include Intelligent agents (in particular exhibiting some aspect of
Artificial Intelligence, such as learning and reasoning), autonomous agents (capable of
modifying the way in which they achieve their objectives), distributed agents (being executed on
physically distinct computers), multi-agent systems (distributed agents that do not have the
capabilities to achieve an objective alone and thus must communicate), and mobile agents
(agents that can relocate their execution onto different processors).
 Affective Computing:
Affective computing is the study and development of systems and devices that can recognize,
interpret, process, and simulate human affects. It is an interdisciplinary field spanning computer
sciences, psychology, and cognitive science. While the origins of the field may be traced as far
back as to early philosophical enquiries into emotion, the more modern branch of computer
science originated with Rosalind Picard's 1995 paper on affective computing. A motivation for
the research is the ability to simulate empathy. The machine should interpret the emotional state
of humans and adapt its behavior to them, giving an appropriate response for those emotions.
 Nanotechnology:
Nanotechnology is very diverse, ranging from extensions of conventional device physics to
completely new approaches based upon molecular self-assembly, from developing new materials
with dimensions on the nanoscale to direct control of matter on the atomic scale.
Nanotechnology entails the application of fields of science as diverse as surface science, organic
chemistry, molecular biology, semiconductor physics, micro fabrication, etc.

10. 10
Scientists debate the future implications of nanotechnology. Nanotechnology may be able to
create many new materials and devices with a vast range of applications, such as in medicine,
electronics, biomaterials and energy production. On the other hand, nanotechnology raises many
of the same issues as any new technology, including concerns about the toxicity and
environmental impact of nanomaterials, and their potential effects on global economics, as well
as speculation about various doomsday scenarios. These concerns have led to a debate among
advocacy groups and governments on whether special regulation of nanotechnology is
warranted.
 Biometrics:
Biometrics refers to the identification of humans by their characteristics or traits. Biometrics is
used in computer science as a form of identification and access control. It is also used to identify
individuals in groups that are under surveillance.
Biometric identifiers are the distinctive, measurable characteristics used to label and describe
individuals. Biometric identifiers are often categorized as physiological versus behavioral
characteristics. A physiological biometric would identify by one's voice, DNA, hand print or
behavior. Behavioral biometrics is related to the behavior of a person, including but not limited
to: typing rhythm, gait, and voice. Some researchers have coined the term behaviometrics to
describe the latter class of biometrics.

APPLICATION
The various applications where ambient intelligence can be used:-
 Smart Homes:
Ambient Intelligence is allowing the home itself to possess intelligence and make decisions
regarding its state and interactions with its residents. The AmI specification may include the
Meaningful environment is the house, including the backyard and a portion of the front door as
these areas also have sensors. Objects are plants, furniture, and so on.
 Health – Related Applications:
Hospitals can increase the efficiency of their services by monitoring patients’ health and progress
by performing automatic analysis of activities in their rooms.
Health services at hospitals could use a link to patients home via a mobile phone to health
sensors, for example, during recuperating from an operation or during long-term treatment of
some disease, e.g. cancer.
 Public Transportation sector:
Public transport can benefit from extra technology including satellite services, GPS-based spatial
location, vehicle identification, image processing and other technologies to make transport more
fluent and hence more efficient and safe.
Based on the time needed to connect two locations with sensors, the system can also predict the
speed of each unit. Examples of objects in this environment are tracks and stations. Interactors
are trains, drivers and command centre officers. Sensors are used for identification purposes
based on ID signals sent from the train. Other signals can be sent as well, e.g., emergency status.
Actuators will be signals coordinating the flow of trains and messages that can be delivered to
each unit in order to regulate their speed and the time they have to spend at a stop. Contexts of
interest can be “delays” or “stopped train”. One interaction rule can be “if line blocked ahead and
there are intermediate stops describe the situation to passengers”.

14. 14
 Education Services:
Education-related institutions may use technology to create smart classrooms where the modes of
learning are enhanced. The objects within a classroom or play ground are tables and other
available elements. The interactors are students and teachers. The sensors will identify who is
using what scientific kit and that in turn will allow monitoring of how long students are involved
with a particular experiment. Actuators can be recommendations delivered to wristwatch-like
personalized displays. Contexts of interest can be “student has been with a single
experimentation kit for too long” or “student has not engaged in active experimentation”. The
first context will trigger a rule “if student has been interacting with one single kit for more than
20 minutes advise the student to try the next experiment available” whilst the second one can
send a message to a tutor, such as “if student has not engaged for more than 5 minutes with an
experiment then tutor has to encourage and guide the student”.
 Emergency services:
Safety-related services like fire brigades can improve the reaction to a hazard by locating the
place more efficiently and also by preparing the way to reach the place in connection with street
services.
Streets can be equipped with sensors to measure passage of traffic within the areas through
which the fire brigade truck might go through in order to reach the place where the emergency is
located. Objects here will be streets and street junctions. Interactors will be cars. Actuators can
be traffic lights as they can help speed the fire brigade through. A context will be a fire occurring
at peak time with a number of alternative streets to be used. An interaction rule can be “if all
streets are busy, use traffic lights to hold traffic back from the vital passage to be used”.
 Production-oriented places:
Companies can use RFID sensors to tag different products and track them along the production
and commercialization processes. This allows identifying the product path from production to
consumer and helps improving the process by providing valuable information for the company
on how to react to favorable demand and unusual events like products that become unsuitable for
sale.

15. 15
Sensors can track the flow of items at critical bottlenecks in the system and the system can
compare the current flow with a desired benchmark. Decision makers can then take decisions on
how to proceed and how to react to the arrival of new materials and to upcoming demands.
Different parts of the plant can be de/activated accordingly. Similarly, sensors can provide useful
information on places where there has been a problem and the section has stopped production,
requiring a deviation in flow. Objects here are transportation belts and elements being
manufactured whilst actuators are the different mechanisms dis/allowing the flow of elements at
particular places. A context can be “a piece of system requiring maintenance” and a related
interaction rule can be “if section A becomes unavailable then redirect the flow of objects
through alternative paths”.
 Public Surveillance
Sensors are enriched CCTV cameras on street or on transport, monitored by security guards.
Integrators are law abiding citizens and potential muggers. A context can be “if a person is
attacked, provide an alarm, issue a verbal warning in-situ to deter attacker and activate a rescue
from the nearest police station or security guard”. Bidirectional voice channels can be used. Of
course AmI requires that the sensing, decision making and actuator are automated. In future this
can be achieved with image and sound processing, reasoning for the identification of an
emergency situation and text-to-speech warnings delivered to the offender.

16. 16
ISSUES
 Social issues
In order to be accepted, AmI must be driven by primarily humanistic and not technological
goals. It is assumed that everyday life skills will rise because of rising opportunities and means
of personal expression and interaction. At work too there are likely to be rising skill demands.
Some will be higher requirements for the technological expertise, but if the AmI manifesto is to
be achieved the main skills rise will be in social know-how and information manipulation.
Therefore, there are still many vague issues, some of which may not become clear until AmI
becomes reality. Can AmI reduce (mental) health risks from information stress, virtual identities
and information overloads? There is also already discussed issue: privacy. Technological
developments are outpacing regulatory adjustments. To what extent can people be protected in
AmI landscape? Furthermore, AmI should be controllable by the ordinary people; otherwise
there will be a lack of social acceptance. So, there is a need for developing technologies which
will enable people to decide what level of access they have and when. Besides, the privacy is not
only issue that may endanger the acceptance of Ambient Intelligence. We must not neglect that
there are people who simply do not like this vision. Regardless of privacy. This will also be a
great challenge for the supporters of Ambient Intelligence. Encouraging sound the word of Mark
Weiser:
“Ubiquitous computing is roughly the opposite of virtual reality, where virtual reality puts people
inside a computer-generated world; ubiquitous computing forces the computer to live out here in
the world with people.”
 Business issues
An interested reader may pose the following questions: Who will make AmI work? Who will
produce it? Who will make money? How will AmI change the way people work, think and
learn? These are all undoubtedly hard questions. On the other hand, some developments can be
predicted even now.

17. 17
According to the ISTAG report, the new emerging business landscape will have the following
features:
 Initial premium value niche markets where interfaces are needed to support human
performance in fast moving and highly delicate situations.
 High access-low entry cost based on a loss leadership model in order to create economies
of scale.
 Self-provision models based upon the network of very large user communities providing
information at near zero cost. As for the way the companies act in the market, the most
spread form will be partnerships and that due to two reasons. Firstly, very large sums of
investment are involved. Secondly, the technological developments require cross-
disciplinary and cross-sectoral capabilities.
 Technological issues
A set of common technological requirements would look like this:
 Hardware must be “very unobtrusive”. The reasons for this are pretty obvious, since AmI
must be nearly invisible. It is thus necessary to make detailed researches in micro and
optical electronics. Molecular and atomic manipulation techniques will be needed to
produce smart materials and nanotechnologies. Besides, technologies needed to
develop “mechanisms” for self-generating power usage in objects are also necessary.
 A seamless mobile/fixed web-based communications infrastructure needs to be
developed, for ubiquitous communication demands omnipresent communication. But, it
is clear that the networks will be very heterogeneous and complex. Therefore, it is
necessary to completely integrate mobile and fixed and radio and wired networks.
Probably all the networks will be operating with some equivalent of the IP technology.
 In the AmI world there will be uncountable interoperating devices. What is necessary
here is that networks be configurable on the ad hoc basis due to a specific task with
variable actors and components. As for databases, they should be accessible on demand
from anywhere in the system.
 The greatest challenge would consist in creating systems that are intuitive in use. Here we
point to the important role of artificial intelligence. There is also need for developing

18. 18
interfaces able to recognize speech and gesture as well as those that are context sensitive
and capable of information filtering and presentation.
 There will be a great demand to provide security in such an environment. We have
already discussed how sensitive this matter is in terms of social acceptance. But it is the
task of technicians to provide the needed security, i.e. systems that are secure against
deliberate misuse. The possible techniques are ID authentication, micropayment systems
or biometrics (fingerprints, iris scanning, and speech).

RESEARCH WORK
Research in Ambient Intelligence is proceeding at a tremendous pace, but so far outcomes have
been witnessed in specific domains and specific applications. Various required technologies for
ambient intelligence are already available, including smart mobile phones, sensors, ad-hoc
networks, and computing, but still requiring some advancements in their integration and
scalability. Some technological advancement that are helping to realize ambient intelligence
include energy scavenging wireless sensors, advancements in RFID technology by
nanoelectronics, specialized low power radio for sensor communication like Ultra
Low Power (ULP) Bluetooth and integration technology like MEMS. Below is a brief
description of the work done in the areas of physical selection, local and wireless sensor
connectivity, context awareness, natural multimodal interfaces, and sensors connected to internet
services.
The products which have been researched are as follows:-
 Internet Fridge
 Karotz
 Moores Cloud
 HomeOS
 SmartTvs
 CeNSE
 Connected Cars

20. 20
FUTURE SCOPE
Ambient Intelligence is establishing fast as an area where a confluence of topics can coverage to
help society through technology. There are still many challenges ahead and improvements are
needed at all levels: infrastructure, algorithms and human-computer interaction for AmI systems
to be widely accepted and more important of all, be useful to society.
Many AmI applications relying upon wireless sensors are at the mercy of the battery life for the
sensors. Challenge is to model multiple residents in an environment. Challenge for AmI
researches is to design self-testing and self-repairing AmI software. Issues related to security and
privacy for AmI systems.

21. 21
CONCLUSION
The introduction of AmI in a home environment will have an impact on personal lives in several
ways. The time gained will allow people to spend more time with their family and friends.
Convenience, money, time savings, security, safety and entertainment reduce the stress leading
to an overall higher quality of life. However, the ability to prepare or complete more and more
everyday tasks such as shopping or banking at home, potentially leads to reduced face-to-face
interaction between people or, at least, to selective interaction restricted to mainly family and
friends.
The disadvantage is that every node and the system as a whole need protection.
Research must, therefore, focus on developing user-friendly low-cost solutions with a high level
of network security. Managers of the various companies intending to produce and sell AmI
technology must agree on common networking standards, which are a major factor determining
future success or failure.
