PERVASIVE COMPUTING
INTRODUCTION
☻Pervasive computing (also called ubiquitous computing) is the growing
trend towards embedding microprocessors.
☻ The words pervasive and ubiquitous mean "existing everywhere".
☻The aim of Pervasive Computing is for computing available wherever it's
needed. It spreads intelligence and connnectivity to more or less
everything.
☻Ships, Aircrafts, Cars, Bridges, Tunnels, Machines, Refrigerators, Door handles,
Lighting fixtures, Shoes, Hats, Tools, Homes and even things like our coffee
mugs and even the human body embedded with chips
☻Mobile Internet access, Third-generation wireless communication, Handheld
devices, and Bluetooth have made pervasive computing a reality.

changes its partners as it
moves or as the context
changes.

EVOLUTION & RELATED FIELDS
• Two distinct earlier
steps in this
evolution:
DİSTRİBUTED
SYSTEMS
MOBİLE
COMPUTİNG
RELATED FIELDS
SENSOR
NETWORKS
• It consists of computing devices equipped with sensors, a wireless
radio, a processor, and a power source.
• Physical environment (e.g., environmental pollutions, wildlife).
HUMAN
COMPUTER
INTERACTİON
• It is the study of interaction between people (users) and
computers.
• Basic goal-more user-friendly and receptive to the user's needs.
• Long term goal-to design systems that minimize the barrier
between the human's cognitive model.
ARTİFİCİAL
INTELLİGENCE
• “Artificial Intelligence is a branch of science which deals with helping
machines find solutions to complex problems in a more human-like fashion”.
• AI is generally associated with Computer Science, but it has many important
links with other fields such a Maths, Psychology, Cognition, Biology and
Philosophy, among many others.
Examples of Pervasive Computing Technologies
Advanced high bandwidth networking services
Networked devices, sensors, instruments, interfaces
Information and computational resources
Telecommunication including global wireless voice
and data broadband networks
Human-machine interaction technologies
Software "agent" technologies
THEMES OF PERVASIVE COMPUTING
Automated
capture
Context-aware
Ubiquitous
services
Natural/Implicit
interfaces
AUTOMATED CAPTURE
• Motivation
– Record-taking is hard
– Multiple streams of
information need to be
captured
– Machines are better at
some of these things than
we are
• Examples
Meeting capture (scribe at
Xerox PARC), Mark Weiser
Classroom 2000
LIVE BOARDS
CONTEXT-AWARE COMPUTING
• Computing services sense aspects of
environment (location, user
emotion,…) and tailor provided
services
• Walk into conference room, my email
is projected on a big screen there
EXAMPLES
• Active Badge & PARCTab
• Shopping assistant
• Cyberguide
• Perception system for recognizing
user moods from their facial
expressions
• House where position is sensed and
temperature adjusted automatically

REAL TIME APPLICATIONS
SMART CLOTHING
►Conductive textiles and inks
print electrically active patterns
directly onto fabrics.
►Sensors based on fabric
monitor pulse, blood pressure,
body temperature.
►Invisible collar microphones
►Game console on the sleeve?
REAL TIME APPLICATIONS
INTERACTIVE FLEX POSTERS
 Flexes that
communicate with the
person automatically
in a building and then
provide him the
information about his
office and the venue
of his meeting that his
held.
REAL TIME APPLICATIONS
PILL CAM
 Miniature camera
 Diagnostic device
 It can be
swallowed
 Once swallowed it
gives the data
about the
functioning of the
vital organs in our
body .
ONGOING RESEARCH PROJECTS
 IBM ‘s “smarter planet “
 The project is about building
a smarter planet by including
everyday case scenarios like
parking the car in a place by
communicating with another
car.
FUTURE ASPECTS
 Cell phones will ask the
landline phone what its
telephone number is and
will forward our calls to it.
 Wrist watches will monitor
our sugar
 Cars will use the Internet to
find an open parking space
or the nearest vegetarian
restaurant inform the owner
of the needed service or
automatically install the
necessary (software) repair
 Digi-tickers or implanted
heart monitors in heart
patients will talk wirelssly to
computers, which will be
trained to keep an eye open
for abnormalities.
CONCLUSION
 Pervasive computing in an increasingly networked world continues
to affect more and more of the world's population. Although this is a
global phenomenon, regional and national social and cultural factors
will directly influence the technologies and promise of pervasive
computing.
 Pervasive Computing - the next era of computer science.
PervasiveComputing.net is intended to be a information and
news website. It will cover various new developments happening in
pervasive computing area - basically mobile computing, sensors,
networking, security/privacy, ubiquitous access to information, and
related fields.
