LIVING IN THE I.T ERA UBIQUITOUS COMPUTING

UBIQUITOUS COMPUTING

It is also called as pervasive computing.

The word pervasive and ubiquitous means “Existing Everywhere”

It is a concept of software engineering and

computer science where computing is made to

appear anytime and everywhere. Ubiquitous

computing can occur using any device, in any

location, and in any format.

It is the use of computers in everyday life.

MARK WEISER

The father of ubiquitous computing is

~~~~~~ who was also the chief

scientist at XEROX PARC (Palo Alto

Research Center) in the US and coined

the term “Ubiquitous Computing”

around 1988.

Researcher in the C.S. lab at research

center first articulated the idea of

ubiquitous computing in 1988 on a

research paper called “The Computer of

the 21st Century”

ZERO WAVE

Historical Context – Ubiquitous Computing

• Computer less Computing

• 1930-1940

• Computer are theoretical technology

• Establish Fundamental Limits on

• Computability

FIRST WAVE

Historical Context – Ubiquitous Computing

• MAIN FRAME Computing

• 1960-1970

• Massive computers to do

• simple data processing

• Few computers in the world

SECOND WAVE

Historical Context – Ubiquitous Computing

• Desktop Computing

• 1980-1990

• Business Applications Drive usage

• One computer per desk

• Computers connected in intranets to

• a massive global networks

• All wired

Third WAVE

Historical Context – Ubiquitous Computing

• Ubiquitous Computing

• 2000 - Present

• Information creation, access communication

• drive usage

• Multiple computers per environment / person

• WAN’s LANs, PANs, ad-hoc networking

• wireless

• Computer disappearing

UBIQUITOUS COMPUTING (2nd Definition)

The idea that almost any device, from

clothing to tools to appliances to cars to

homes to the human body to your coffee

mug, can be embedded with chips to

connect the device to an infinite network

of devices.

It supports one user to many computers.

We start working with computers and

not through them

Goal of Ubiquitous Computing

To create an environment where the connectivity of devices embedded in such a way that connectivity is

unobtrusive and always available.

Devices characteristics are very tiny – even

invisible – small, inexpensive, robust networked

processing devices either mobile or embedded in almost any type of objects such as cars, tools,

appliances, clothing and various consumer goods –

all communicating through increasingly

interconnected networks.

Examples:

Computer sensors in your floor that can monitor

your physical health

Computer in your car that can assist you when you

drive to work

Replacement of old electric meter with smart meter

Virtual Reality vs Ubiquitous Computing

Virtual Reality

• Puts people inside a computer-generated three dimensional world

Ubiquitous Computing

• Forces the computer to live out here in the world with people

• Integrating of human factors, computer science, engineering and social sciences

Ubiquitous

Computers being integral

into the world and not

merely just a computing

device.

Augmented

Using device in order to

create an overlay on

virtual world

Virtual

Humans enters to a

computer enhance

environment or computer

world

Computer dictates the

senses , views and

interaction

Ubiquitous Computing vs Cloud Computing

• In ubiquitous computing a method of enhancing computer use by making many computer available but at the same time invincible or effectively making them disappear

• Sending ANY DATA to ANY NETWORK using

• ANY DEVICE at ANYTIME and ANYWHERE

• Involves 3 Converging Areas ( COMPUTING , COMMUNICATIONS , USER INTERFACE)

• Computing Devices can be seen in many forms and in many devices

• Communications could be through wired or wireless

• User Interface development of sensors and SoM and SBC allowing sensing data/information autonomous

Cloud Computing

• Style of computing which is dynamically stable, virtualized resource are often provided in the

  internet

• User needs only to run interface software and cloud network runs the rest

• Requires in pay-per use and on demand

• Works is migrated from different

  physical resource

Pervasive Computing

• Everyday Objects

  becoming computer nodes

• Emerging but not widely

  deployed

• Adding computing to

  everyday objects

Cloud Computing

• Running applications on

  the internet rather than

  locally

• Already put into practice

• Hosting Services
