What is “Ubiquitous”?U.biq.ui.tous (yōō-bĭk'wĭ-təs)

existing or being everywhere, esp. at the same time; omnipresent: ubiquitous fog; ubiquitous little ants.

Mark Weiser: the father of ubiquitous computing

has called UC “…highest idea is to make a computer so embedded, so fitting, so natural, that we use it without even thinking about it.”

“In the 21st century the technology revolution will move into the everyday, the small and the invisible…”

“The most profound technologies are those that disappear. They weave themselves into the fabrics of everyday life until they are indistinguishable from it.”

What is Ubiquitous Computing???Ubiquitous computing is the method of enhancing computer use by making many computers available throughout the physical environment, but making them effectively invisible to the user

– Mark Weiser

An environment in which people interact with embedded computers (processors) and in which networked devices are aware of their surroundings (to being pervasive)

Three Waves of Computing

● Mainframe computing era– massive computers to execute big data processing

applications– very few computers in the world

● Desktop computing era– one computer at every desk to help in business related

activities– computers connected in intranets to a massive global network(internet), all wired

● Ubiquitous computing era– tens/hundreds of computing devices in every room/person,

becoming “invisible” and part of the environment

Computing Trends…

How to achieve Ubiquity???Make Computing mobile and connected

• Instrument the person

Instrument the physical surroundings

What makes it possible…Processing

cheaper, faster, smaller, more energy efficientStorage

Big, fast and small in size.Networking

global, local, ad-hoc, low-power, high bandwidth, low latencies

SensorsDisplays

projection, flexible materials, power consumption

Objects(tabs ,boards and pads)

Technologies continued…Pervasive Computing:An environment in which people interact with

embedded (and mostly invisible) computers (processors) and in which networked devices are aware of their surroundings and peers and are able to provide services or use services from peers effectively

Wearable Computing:Wearable technology,  tech togs, or  fashion

electronics are clothing and accessories incorporating computer and advanced electronic technologies.

In computing , Ambient Intelligence  refers to electronic environments that are sensitive and responsive to the presence of people. Ambient intelligence is a vision on the future of consumer electronics ,telecommunications and computing.

As these devices grow smaller, more connected and more integrated into our environment, the technology disappears into our surroundings …….TOWARDS

Ubiquitous vs Cloud Computing

General Ubicomp Features There are three general features that

are shared across a wide variety of ubicomp applications.

These features are :1. the ability to provide transparent

interfaces2. the ability to automatically adapt the

behavior of a program based on knowledge of the context of its use,

3. the ability to automate the capture of live experiences for later recall.

GUF - (1) TRANSPARENT INTERFACES Ubicomp Vision: “pervasive computation

without intrusion.” Remove the physical barrier between user

and computational deviceKeyboard and mouse are still the most

commonly used interfaces !!Need:

flexible interfaces Varied interfaces that can provide similar

functionality

GUF - (2) CONTEXT AWARENESS Context – information about the environment in

which the application operates and reacts accordingly.

LOCATION and TIME are simple examples of context !

Context aware application:is one which can capture the contextassign meaning to itchange behavior accordingly

Need:Applications that are context aware and

allow rapid personalization of their services.

GUF - (3) AUTOMATED CAPTURECapture everyday experiences and make

the records available for later use.Constraints:

Multiple streams of informationTheir time synchronizationTheir correlation and integration

Need:Automated tools that support capture,

integration and future access of info.

Sensors and context-aware solutions are on the market already

Few Examples…

Challenges of UbicompHow to integrate mobile

communicators into complex information infrastructures?

What effect will they have on work and leisure?

Secure and reliable servicesHow to develop and manage adaptable,

context-aware software systems?What support is needed within the

network?Power supplies.

Working Example

ConclusionPervasive computing provides an attractive

vision for the future of computing

Computational power will be available everywhere through mobile and stationary devices

Ubiquitous computing is the next generation computing environment with information & communication technology everywhere, for everyone, at all times.

Ubiquitous Computing is all about Human! Because we love comfortable living!!! Sci-fi movie is not far from reality
