INTRODUCTION☻Pervasive computing (also called ubiquitous computing) is the growing

trend towards embedding microprocessors.

☻ The words pervasive and ubiquitous mean "existing everywhere".

☻The aim of Pervasive Computing is for computing available wherever it's needed.  It spreads intelligence and connnectivity to more or less everything.

☻ 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.

PERVASIVE COMPUTINGPervasive computing means.,

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

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

Any network: Access, Notification, Data Synchronization, Queued transactions, Wireless optimization, Security, content adaptation/reformat, development tools, device and user management.

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

computing:Ubiquitous computingCalm technologyThings that thinkEveryware Pervasive internet Ambient intelligenceProactive computingAugmented reality

Characteristics of pervasive computing:

Physical integration: integration between computing nodes and the physical world, e.g., a whiteboard that records what’s on.

Instantaneous Interoperation: devices interoperate spontaneously in changing environments, e.g., a device changes its partners as it moves or as the context changes.

Examples of Pervasive Computing Technologies

THEMES OF PERVASIVE COMPUTING

AUTOMATED CAPTURE• Motivation

– Record-taking is hard– Multiple streams of

information need to be captured

– Machines are better at some of these things than we are

• ExamplesMeeting capture (scribe at Xerox PARC), Mark WeiserClassroom 2000

LIVE BOARDS

CONTEXT-AWARE COMPUTING• Computing services sense

aspects of environment (location, user emotion,…) and tailor provided services

• Walk into conference room, my email is projected on a big screen there

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

recognizing user moods from their facial expressions

• House where position is sensed and temperature adjusted automatically

USES OF PERVASIVE COMPUTING

REAL TIME APPLICATIONS

►Conductive textiles and inks print electrically active patterns directly onto fabrics.

►Sensors based on fabricmonitor pulse, blood pressure, body temperature.

►Invisible collar microphones

►Game console on the sleeve?

SMART CLOTHING

REAL TIME APPLICATIONSINTERACTIVE FLEX POSTERS

Flexes that communicate with the person automatically in a building and then provide him the information about his office and the venue of his meeting that his held.

deviceIt can be

swallowedOnce

swallowed it gives the data about the functioning of the vital organs in our body .

REAL TIME APPLICATIONS

ONGOING RESEARCH PROJECTS IBM ‘s “smarter planet

“ The project is about

building a smarter planet by including everyday case scenarios like parking the car in a place by communicating with another car.

FUTURE ASPECTSCell phones will ask the

landline phone what its telephone number is and will forward our calls to it.

  Wrist watches will monitor our sugar

Cars will use the Internet to find an open parking space or the nearest vegetarian restaurant inform the owner of the needed service or automatically install the necessary (software) repair 

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.

CONCLUSIONPervasive computing in an increasingly networked world

continues to affect more and more of the world's population. Although this is a global phenomenon, regional and national social and cultural factors will 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 in pervasive computing area - basically mobile computing, sensors, networking, security/privacy, ubiquitous access to information, and related fields.
