This document provides an introduction to pervasive computing. Pervasive computing aims to make computing available anywhere through embedding microprocessors in everyday objects. It allows computing power and connectivity to be spread throughout physical environments. Some key aspects covered include ubiquitous access across devices and networks, context-aware computing that tailors services based on environmental factors, and emerging applications in areas like smart clothing, interactive posters, and pill cameras. Ongoing research continues to explore how pervasive technologies can create smarter and more connected systems and environments.

2. 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.

3. PERVASIVE COMPUTING
⚫ Pervasive computing means.,
i Anytime/anywhere: 7 days x 24 hours, global, ubiquitous access.
r Any device: PC, Palm/PDA, cell phone, and so forth.
l Any network: Access, Notification, Data Synchronization, Queued
transactions, Wireless optimization, Security, content
adaptation/reformat, development tools, device and user management.
m Any data: E-mail, Personal Information Manager (PIM); Inter-Intranet;
Public Services.

4. Contd…
⚫ Other terms for pervasive
computing:
 Ubiquitous computing
 Calm technology
 Things that think
 Everyware
 Pervasive internet
 Ambient intelligence
 Proactive computing
 Augmented reality
⚫ Characteristics of pervasive
computing:
 Physical integration:
integration between
computing nodes and the
physical world, e.g., a
whiteboard that records
what’s on.
 Instantaneous
Interoperation: devices
interoperate spontaneously
in changing environments,
e.g., a device changes its
partners as it moves or as the
context changes.

10. THEMES OF PERVASIVE
COMPUTING

11. 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

12. 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

•
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

15. USES OF PERVASIVE
COMPUTING

16. 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?

17. 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.

18. 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 .
REAL TIME APPLICATIONS

19. 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.

20. 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.

21. 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.
Let’s not throw the first stone, but make the first step!
