1990s: Mark Weiser (Xerox PARC)

First to talk about Ubiquitous Computing (PERVASIVE COMPUTING)

The purpose of a computer is to help you do something else.

The best computer is a quiet, invisible servant.

The more you can do by intuition the smarter you are.

The computer should extend your unconscious.

Technology should create calm.

Mark Weiser (1952 1999)

In Hospitals

Wristband patients details, reduces the risk of misidentification

and treatment errors.

In Health Care Centers

Sensors embedded in items of clothing, might allow constant

monitoring of heart rates, body-mass index, blood pressure and

other physiological variables.

Environmental Monitoring

Pervasive computing will allow for continuous real-time data

collection and analysis via remote, wireless devices.

Intelligent Transport Systems

Computers are incorporated into cars via integrated mobile

phone systems, parking sensors & complex engine management

systems.

It is argued that privacy, safety and security can be betterprotected if appropriate procedures and protocols are

integrated into PCS (Pervasive Computing devices).The volume of transmitted data should be kept to a minimumData that require transmission should be encrypted and sent

anonymously (without reference to the owner)

IBM's project Planet Blue

Agricultural activities must go on with pervasive devices

so as to increase the production and decrease the

manual work.

Cell phones will ask the landline phone what its

telephone number is and will forward our calls to it

Remote computers will monitor our health statistics and

will determine when one is in trouble and will take

appropriate action for rescue.

Refrigerators will be connected to the Internet so one

could find out, via cell phone or PDA, what is in it while

one is at the store.

Pervasive computing provides an attractive vision for the future of

computing.

Well, we no longer will be sitting down in front of a PC to get access

to information, instead we use wireless media to access

those things.

As a machine its work is to fulfill the Mans need, but Pervasive

Computing technology fulfills His need as a friend naturally.
