PERVASIVE COMPUTING
By
Ahmed Abdullah Ezaddin
INTRODUCTION
Everyone of us are used to computers that provide
quick computations and communications but have we
ever thought of devices which are very tiny almost
invisible and provide the same function ? Ya !!!!! it is
possible with help of concept called ‘Pervasive
Computing’ .
Based on the vision of Mark Weiser
A DEFINITION…..
 Pervasive computing is the trend towards
increasingly ubiquitous connected computing
devices in the environment, a trend being brought
about by a convergence of advanced electronic
and particularly, wireless- technologies and the
Internet
.
It spreads intelligence and connectivity to more
or less everything.
ADVANTAGES OF PERVASIVE COMPUTING
Quick , efficient and effortless.
It supports a new class of intelligent and portable
appliances or "smart devices" .
It gives people convenient access to relevant
information .
It removes the complexity of new technologies.
UBIQUITOUS VS PERVASIVE
 in Ubiquitous it may be an only computer with
multiple access points and shared user space
(cloud computing)

in Pervasive computers are everywhere, but
they don't have to have an user interface, or
necessarily be controllable by users.
MOBILE VS PERVASIVE
 Mobile implies computers are so small and low
power that can be carried around.
 pervasive implies that are so tiny and cheap
that can be placed inside things that could need
one.
MOBILE VS UBIQUITOUS VS PERVASIVE COMPUTING

Mobile computing is when you bring the
computer with you. Example smartphones,
prisoner anklets.
 Ubiquitous computing is wherever you go, there
is a computer you can use. Example internet
caffee, mainframe terminals.
 Pervasive computing is when computers are
everywhere inside all things, maybe also within
you. Example IoT, Star trek Replicant.
APPLICATIONS
Remote computers will monitor our heath statistics
Cars will use the Internet to find an open parking
space or the nearest vegetarian restaurant for their
owners
Used in Digi-tickers or implanted heart monitors
In development of Smart Clothes.

computerized clothing because it is
made with two fibers that make it
conducive to electricity.
SMART -T-SHIRT
The shirt was being
designed for soldiers in
combat, so that medical
personnel could find the
exact location of a
bullet wound.
The smart shirt can
monitor both heart and
breathing rates
An early prototype of the smart shirt
developed at Georgia Tech
CONCLUSION
Pervasive computing provides an attractive vision for the
future of computing
Computational power will be available everywhere through
mobile and stationary devices
When Edison finally found a filament that would burn, did he
see the possibility of silent but pervasive electrical current
flowing throughout our homes, cars and communities?

WEARABLE DEVICES

INTRODUCTION:
Wearable devices are a new form of mobile
computer system that is subsumed into the
personal space of a user, controlled by the user,
and has both operational and interactional
constancy, i.e., is always on and accessible that
provides exclusive and user-personalized services
14
POWER SUPPLY:
Requirement of desired power will be delivered to
the devices by employing batteries.
Desired power depends upon the device employed
for the application.
Example:
.Texas Instruments (TI) has a device, the bq25570 ,
which can take the 300 to 400 mv that is collected by
energy harvesters and boosts up to an power of 3 to
5 volts.
15
SENSOR:
Sensors are sophisticated devices that are
frequently used to detect and respond to physical
parameter (for example: temperature, blood
pressure, humidity, speed, etc.) into a signal which
can be measured electrically.
Types:
Tactile sensors
Gas sensors
Bio sensors
16
HOME HEALTH and WEARABLE DEVICE INNOVATION
17
ACTIVITY MONITOR:
Sensor: Accelerometer
Senses each step, App converts steps
in to calories burned.
Tracks quality of sleep.
Fit Bit
TRICODER:
Sensor: Temperature
Heart Rate Sensing
ECG
Heart Rate Velocity
Blood Pressure
Blood Oxygen Levels

SMART WATCHES:
Indicates temperature
provides streaks
keeps track of delivery
status and displays.
keeps tracks of the day to
day activities of news, top
stories.
19
Displays personal
activities which are to
be taken care
.provides googled
information.
provides
information
regarding on going
activities of what to
be happen in our
location.
keeps tracks of
travelling and views
the status whenever
we required,.
20
DIGITAL PARENTING:
The system captures the sound in
the baby's room so parents can
listen in on their phone or tablet
like any standard monitor. It's a
bold move, but works with the
2-way communication functionality and the nightlight /
lullaby music modes.
It records and streams in HD and the infrared vision
wide lens makes it a great option for bed time. For extra
security, the Home camera also monitors air quality.
21
SMART CLOTHES TO SMART OBJECTS:
Smart clothes keeps
tracks of the fitness level
by providing information
regarding the burned
calories of the user.
Smart clothes are able to
regulate the temperature
change of the body by
continuous monitoring.
22
IN INDUSTRY AND MILITARY:
The critical operations of
the industrial which are
impossible are achieved
progress due to the ease
use of wearable devices.
Wearable technology
provides the healthy
conditions to the workers in
un-hygienic conditions.
23
The wearable computer will offer
situational awareness to the infantry
soldier that will help separate friend
from foe(enemies).
Wearable computers will help soldiers
to use digitally distributed orders, map,
and intelligence, each soldier to
communicate and to exchange video of
what they see seamlessly with his
comrades within a networked unit.
plays major role in exercise to
retrieve hostages by passing information
about the location.
24
WEARABLE SKIN TATTOOS:
wearable tattoo — essentially, a
wearable skin which is an “thin,
flexible devices that can stretch,
bend and twist seamlessly with our
bodies and posses capabilities of
store data and deliver drugs .”
 A skin-like polymer material was
layered with stretchable, motion and temperature
sensors, resistive RAM, micro heaters and drugs to be
delivered through skin.
25
The patch is about four centimeters
long, two centimeters wide and 0.003
millimeters thick. One possible use case
is on-the-spot delivery of medicine in
response to muscle movement, such as
for epilepsy or Parkinson’s disease.
In Motorola’s vision, the skin tattoo can talk to larger
devices like smart phones or Google Glass through
Bluetooth, and, at least in the application, includes a
mike and a power source it can function as a lie
detector, measuring galvanic skin response.
26
AS Wearable Technology develops
marketing will use consumer’s personal
biometric to sell products and services.
