The document discusses pervasive computing, which refers to microprocessors being embedded everywhere and computing being available anywhere. It is enabled by technologies like mobile internet access, wireless communication, and Bluetooth. Pervasive computing allows access from any device, on any network, with any data. It aims to spread intelligence and connectivity to more or less everything, from ships and aircrafts to coffee mugs and the human body. Some principles of pervasive computing include anytime/anywhere access, physical integration between computing nodes and the physical world, and instantaneous interoperation between devices. Examples of applications include smart clothing, interactive flexible posters, and pill cameras.

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.

Characteristics of pervasive Other terms for pervasive
computing: computing:
Physical integration: Ubiquitous computing
integration between Calm technology
computing nodes and the
physical world, e.g., a Things that think
whiteboard that records Everyware
what’s on.
Instantaneous Pervasive internet
Interoperation: devices Ambient intelligence
interoperate spontaneously
in changing environments, Proactive computing
e.g., a device changes its Augmented reality
partners as it moves or as the
context changes.
11. AUTOMATED CAPTURE
• Motivation
– Record-taking is hard
LIVE BOARDS
– 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
12. CONTEXT-AWARE COMPUTING
• Computing services sense aspects of
environment (location, user
emotion,…) and tailor provided Augmented Reality
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
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. 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 .
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 Cars will use the Internet to
landline phone what its find an open parking space
telephone number is and will or the nearest vegetarian
forward our calls to it. restaurant inform the owner
of the needed service or
automatically install the
Wrist watches will monitor
necessary (software) repair
our sugar
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!
