2- What is Ambient Intelligence?
Ambient Intelligence (AmI) refers to electronic
environments that are sensitive and responsive to
the presence of people.
In an ambient intelligence world, devices work in
concert to support people in carrying out their
everyday life activities, tasks and rituals in
easy, natural way using information and
intelligence that is hidden in the network
connecting these devices.
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.
3How does it differ from before?
- At the same time, more and more people make
decisions based on the effect their actions will
have on their own inner, mental world. This
experience rational way of acting is a change
from the past when people were primarily
concerned about the use value of products and
services and is the basis for the experience
economy. - Ambient intelligence addresses this shift in
existential view by emphasizing people and user
experience. Need to design things from a user's
point of view.
- The interest in user experience has also grown
because of the overload of products and services
in the information society that were difficult to
understand and hard to use in the past. - Ambient intelligence is influenced by
user-centered design where the user is placed in
the center of the design activity and asked to
give feedback through specific user evaluations
and tests to improve the design or even co-create
the design together with the designer or with
other users.
4Great! Where can I buy one?
- In order for AmI to become a reality a number of
key technologies are required
- Unobtrusive hardware (Miniaturisation,
Nanotechnology, smart devices, sensors etc.) -
- Seamless mobile/fixed communication and computing
infrastructure (interoperability, wired and
wireless networks, service-oriented architecture,
semantic web etc.) - Dynamic and massively distributed device
networks, which are easy to control and program
(e.g. service discovery, auto-configuration,
end-user programmable devices and systems etc.). - Human-centric computer interfaces (intelligent
agents, multimodal interaction, context awareness
etc.) - Dependable and secure systems and devices
(self-testing and self repairing software,
privacy ensuring technology etc.)
5UU piece of puzzle Determine Location
- GPS (Global Positioning System), is able to show
ones position on the Earth. GPS satellites, 24 in
all, orbit at 11,000 nautical miles above the
Earth. They are continuously monitored by ground
stations located worldwide. - Pro No need for infrastructure, cheap receivers
Con High buildings, need LOS
2. Cellular Triangulation is a process by which
the location of a radio transmitter can be
determined by measuring either the radial
distance, or the direction, of the received
signal from 2 or 3 different points. The distance
is determined by measuring the relative time
delays in signal from the mobile set to 3 base
stations. Pro Technology here we all have
phones Con Coarse readings, pricey
- 3. 802.11 WiFi . This generally consists of 3
elements. 1. Radio beacons in the environment. 2.
Databases holding beacon location information and
3. Clients which estimate their location from
data . Leaders in the field include Ekahau,
Trapeze Networks and Ubisense. There is also
freely available software solutions such as
PlaceLab although this tends to be much cruder
than the commercial solutions. - Pro Access points generally in place, indoors
Con Coarse readings, Can be pricey
6Determine Location Existing Solutions
- 4. RFID. RFID has seen widespread use across
many different applications. The vast majority of
these applications, however, only use the data
contained in tags within the readers zone,
rather than the location of the tag at any given
time. - The Los Angeles County Sheriff Department
deployed tamper-proof, active RFID tags worn as
wristbands by inmates, and RFID readers
throughout the jail. Each tag links each inmate
to a particular profile in the system, which can
be used to restrict them to certain parts of the
jail, or keep them away from other particular
prisoners.
- The system alerts prison staff if inmates enter
restricted areas or move within a certain range
of specific inmates. Ultimate aim to reduce
violence between inmates deter escape attempts. - Pro Cheap tags, fast scanning, indoors
Con Relatively new, restricted distance
- 5. Ultra Wide Band (UWB). UWB is precisely timed
short bursts of RF energy to provide accurate
triangulation of the position of the transmitting
tag. Since the short time UWB signal is very
broad in frequency spread (typically 1 to 2 GHz
wide) the system can operate on a very low power
output and is robust against interference.
Typically battery-operated radio tags and a
cellular locating system to detect location of
tags. Locating system usually deployed as a
matrix of locating devices (or sensors) . These
sensors determine the locations of the radio
tags. - Pro Accurate Con New, Expensive
7Demo 1 ZigBit Sensor Modules
- This here is a ZigBit device which is a
low-power, high-sensitivity 802.15.4 / ZigBee
module. An impressive functionality in less than
a half square inch of space.
- Wireless Sensor Network Monitor demo here shows
the network topology, sensor data and the signal
quality between the nodes. - The WSN Monitor automatically generates network
topology diagrams as network nodes are detected
and added to the system. - These nodes are then regularly monitored, with
any sensor data received automatically displayed
in charts and tables on a PC screen.
- Figure above is a sample application
demonstrating a building monitoring solution that
features real-time capture and display of
temperature and light levels read from remote
ZigBee sensors.
8Demo 2 Where are you?
- How we can track people and items over an
existing wireless network in order to make the
Ambient Intelligence dream a reality - We generally prefer the 802.11 standards-based,
"pure play method which requires no readers or
new cabling
9Summary
- In an ambient intelligence world, devices work in
concert to support people in carrying out
everyday life activities and tasks that is hidden
in the network connecting thesein a natural way
using information and intelligence devices. - Ambient intelligence emphasizes people and user
experience and ensuring that the technology
disappears into our surroundings until only the
user interface remains visible to users. - AmI specifically focuses on the convergence of
several computing areas. - The first is ubiquitous computing which focuses
on self-testing and self repairing software,
privacy ensuring technology and the development
of various ad hoc networking capabilities that
exploit numerous low-cost computing devices. - The second key area is intelligent systems
research, which provides learning algorithms and
pattern matchers, speech recognition and language
translators, and gesture classification and
situation assessment. Another area is context
awareness which attempts to track and position
objects of all types and represent objects
interactions with their environments. - Finally, an appreciation of human-centric
computer interfaces, intelligent agents,
multimodal interaction and the social
interactions of objects in environments is
essential.
