What is Ubiquitous Computing?
 Ubiquitous computing (ubicomp) is an
advanced computing concept where
computing is made to appear everywhere
and anywhere.
 The idea behind this sort of computing is
to make the computing power disappear in
the environment, but will always be there
whenever needed or in other words it
means availability and invisibility.

Example of a Ubiquitous
Environment:
Lights, Air conditioning, TV's
automatically switch on or off when you
enter or leave.
Sit on your chair and the TV sets your
favourite channel which you usually
watch ay this time of the day.
Route input from 'virtual' keyboard to
nearest suitable display.

 The underlying technologies to support
ubiquitous computing include Internet,
advanced middleware, operating
system, mobile code, sensors,
microprocessors, new I/O and user
interfaces, networks, mobile protocols,
location and positioning and new
materials.

HARDWARE
REQUIREMENTS
 Sensors: A sensor is a converter that measures a
physical quantity and converts it into a signal
which can be read by an observer or by an
instrument.
 Actuators: An actuator is a type of motor for
moving or controlling a mechanism or system. It is
operated by a source of energy, typically electric
current, hydraulic fluid pressure, and converts that
energy into motion.

HARDWARE
REQUIREMENTS
 PORTABLE WIRELESS RFID READER/WRITER:
Radio-frequency identification (RFID) is the wireless
non-contact use of radio-frequency electromagnetic
fields to transfer data, for the purposes of automatically
identifying and tracking tags attached to objects.

HARDWARE
REQUIREMENTS
1.Display Devices:
 Liquid Crystal technologies (LCD)
 Organic LED based Display
2.Storage technologies:
 Non-volatile Flash Memory
 Battery-backed RAM

DESIGNING
 Nanotechnology:
 The trend toward miniaturization of computer
components down to an atomic scale is known
as nanotechnology. Nanotechnology involves
building highly miniaturized computers from
individual atoms or molecules acting as
transistors, which are the heart of the
computer chip. The number of transistors in a
chip is indicative of its power. Therefore,
nanotechnology’s extreme miniaturization of
transistors allows for impressive levels of
computing power to be put into tiny packages,
which can then be unobtrusively tucked away.

DESIGNING
 Wireless:
 Wireless computing refers to the use of wireless
technology to connect computers to a network.
Wireless computing is so attractive because it allows
workers to escape the tether of a network cable and
access network and communication services from
anywhere within reach of a wireless network.
Wireless computing has attracted enormous market
interest, as witnessed by consumer demand for
wireless home networks, which can be purchased for
several hundred dollars. The second author has a
three-computer wireless network in his home.

DESIGNING
 Another approach is to implement the
target system in a simulator and do the
testing there. Although the focus of this
technique should lie on the design of the
protocols, a lot of time goes into the
implementation instead of the design.
Addressed tests are generally done under
unrealistic conditions with a very small
subset of features, a small number of
nodes and unrealistic environment. The
predictability gained from those isolated
tests is basically zero

Applications
1. Smart Home for Elderly
 An elderly person lives in an apartment
with being handicapped in various
ways.
 His relatives wants to keep an eye on
him 24/7.

Objectives
 To develop a monitoring and sensing
system.
 To capture vital signs of elderly.
 To gather data and make it accessible.

System Architecture
 Database Server.
 Cameras & Microphones.
 Sensors.
a. Floor Pressure.
b. Infra-red.
c. Light.
d. Pulse oximeter & Blood pressure.

An overall layout of the elderly
monitoring system

Database stores the information.
Cameras and Microphones gathers video and audio
information.
FPS is used to track residents or detect furniture positions
Infra-red sensor to detect infra-red sources.
Pulse oximeter & Blood pressure are medical wearable
sensors.

Health Monitoring
 postoperative monitoring of patients;
 monitoring of patients with chronic
diseases;
 social networking of relatives and peers
for monitoring of elderly;
 lifestyle and general well-being
monitoring (e.g., to deal with obesity);

Health Monitoring
 wellness and exercise monitoring;
 monitoring vitals and status of soldiers
and firefighters;
 emergency medical care and mass
casualty events;
 computer-assisted rehabilitation and
therapy; and
 development of new emergency
services with prolonged monitoring.

CONCLUSION
 The Ubiquitous computing due to its context
awareness and the natural interaction provides an
intelligent environment in which user can easily avail
desired services in an intelligent manner such as
identification of user likings place time etc.
 In the long term as pervasive computing is integrated
into everyday objects, they become networked
information control systems that are presently
centralized in industry, transport, the service industry
and the public sector can be decentralized.
 Thus we can say that ubiquitous computing could be
the next wave in the technology of computers
