2. 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 whereverits needed. 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 coffee mugs and even the human body embedded with chips Mobile Internet access, Third-generation wireless communication, Handheld devices, and Bluetooth have made pervasive computing a reality. 3. PERVASIVE COMPUTING Pervasive computing means.,i Anytime/anywhere: 7 days x 24 hours, global, ubiquitous access.r Any device: PC, Palm/PDA, cell phone, and so forth.l Any network: Access, Notification, Data Synchronization, Queuedtransactions, Wireless optimization, Security, contentadaptation/reformat, development tools, device and user management.m Any data: E-mail, Personal Information Manager (PIM); Inter-Intranet;Public Services. 4. Contd Characteristics of pervasive Other terms for pervasivecomputing: computing: Physical integration: Ubiquitous computingintegration between Calm technologycomputing nodes and thephysical world, e.g., a Things that thinkwhiteboard that records Everywarewhats on. Instantaneous Pervasive internetInteroperation: devices Ambient intelligenceinteroperate spontaneouslyin changing environments, Proactive computinge.g., a device changes its Augmented realitypartners as it moves or as thecontext changes. 5. PRINCIPLES OF PERVASIVECOMPUTING 6. CLASSIFICATIONINFRASTRUCTURE SYSTEMSPERSONAL SYSTEMS Attention, Complexity, Privacy, Security, And Extensibility. 7. EVOLUTION & RELATED FIELDS Two distinct earlier steps in this evolution:DSTRBUTED SYSTEMSMOBLE COMPUTNG 8. RELATED FIELDS 9. Examples of Pervasive Computing Technologies 10. THEMES OF PERVASIVECOMPUTING 11. AUTOMATED CAPTURE Motivation Record-taking is hard LIVE BOARDS Multiple streams of information need to be captured Machines are better at some of these things than we are ExamplesMeeting capture (scribe atXerox PARC), MarkWeiserClassroom 2000 12.

ONGOING RESEARCH PROJECTS IBM s smarter planet The project is aboutbuilding a smarter planetby including everyday casescenarios like parking thecar in a place bycommunicating withanother car. 20. FUTURE ASPECTS Cell phones will ask the Cars will use the Internet tolandline phone what itsfind an open parking spacetelephone number is and will or the nearest vegetarianforward our calls to it. restaurant inform the owner of the needed service or automatically install theWrist watches will monitor necessary (software) repairour sugar Digi-tickers or implanted heart monitors in heart patients will talk wirelssly to computers, which will be trained to keep an eye open for abnormalities. 21. CONCLUSION Pervasive computing in an increasingly networked worldcontinues to affect more and more of the worlds population.Although this is a global phenomenon, regional and nationalsocial and cultural factors will directly influence thetechnologies and promise of pervasive computing. Pervasive Computing - the next era of computer science. is intended to be a informationand news website. It will cover various new developmentshappening in pervasive computing area - basically mobilecomputing, sensors, networking, security/privacy, ubiquitousaccess to information, and related fields.Lets not throw the first stone, but make the first step! 22.
