INTRODUCTION

Pervasive computing (also called ubiquitous computing ) is the growingtrend towards embedding microprocessors .

The words pervasive and ubiquitous mean " existing everywhere ".

The aim of Pervasive Computing is for computing available wherever it'sneeded. It spreads intelligence and connnectivity to more or lesseverything.

Ships, Aircrafts, Cars, Bridges, Tunnels, Machines, Refrigerators, Door handles,Lighting fixtures, Shoes, Hats, Tools, Homes and even things like our coffeemugs and even the human body embedded with chips

Mobile Internet access, Third-generation wireless communication, Handhelddevices, and Bluetooth have made pervasive computing a reality.

PERVASIVE COMPUTING Pervasive computing means.,

1. Anytime/anywhere: 7 days x 24 hours, global, ubiquitous access.

2. Any device: PC, Palm/PDA, cell phone, and so forth.

3. Any network: Access, Notification, Data Synchronization, Queued

transactions, Wireless optimization, Security, contentadaptation/reformat, development tools, device and user management.

4. Any data: E-mail, Personal Information Manager (PIM); Inter-Intranet;Public Services.

Characteristics of pervasivecomputing:Physical integration :integration between

computing nodes and the physical world, e.g., awhiteboard that recordswhats on. Instantaneous Interoperation :devices interoperatespontaneously in changingenvironments, e.g., a devicechanges its partners as itmoves or as the contextchanges.

RELATED FIELDS It consists of computing devices equipped with sensors, a wireless

radio, a processor, and a power source. Physical environment (e.g., environmental pollutions, wildlife).

SENSORNETWORKS

It is the study of interaction between people (users) andcomputers.

Basic goal -more user-friendly and receptive to the user's needs. Long term goal -to design systems that minimize the barrier

between the human's cognitive model.

HUMANCOMPUTER

INTERACTON

Artificial Intelligence is a branch of science which deals with helpingmachines find solutions to complex problems in a more human- like fashion.

AI is generally associated with Computer Science, but it has many importantlinks with other fields such a Maths, Psychology, Cognit ion , Bi ology andPhilosophy, among many others.

AUTOMATED CAPTURE Motivation

Record-taking is hard Multiple streams of

information need to be

captured Machines are better at

some of these things thanwe are

CONTEXT-AWARE COMPUTING Computing services sense aspects of

environment (location, useremotion,) and tailor providedservices

Walk into conference room, my emailis projected on a big screen there

EXAMPLES Active Badge & PARCTab Shopping assistant Cyberguide Perception system for recognizing

user moods from their facialexpressions

House where position is sensed andtemperature adjusted automatically

FUTURE ASPECTS Cell phones will ask thelandline phone what itstelephone number is andwill forward our calls to it.

Wrist watches will monitorour sugar

Cars will use the Internet tofind an open parking spaceor the nearest vegetarianrestaurant inform the owner

CONCLUSION

Pervasive computing in an increasingly networked world continuesto affect more and more of the world's population. Although this is aglobal phenomenon, regional and national social and cultural factorswill directly influence the technologies and promise of pervasive

computing.Pervasive Computing - the next era of computer science.PervasiveComputing.net is intended to be a information and

news website. It will cover various new developments happening inpervasive computing area - basically mobile computing, sensors,networking, security/privacy, ubiquitous access to information, andrelated fields.

Lets not throw the first stone, but make the first step!
