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 its 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 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, Queued transactions, Wireless optimization, Security, content adaptation/reformat, development tools, device and user management. m Any data: E-mail, Personal Information Manager (PIM); Inter-Intranet; Public Services.
Contd… Characteristics of pervasive Other terms for pervasive computing: computing: Physical integration: Ubiquitous computing integration between Calm technology computing nodes and the physical world, e.g., a Things that think whiteboard that records Everyware what’s on. Instantaneous Pervasive internet Interoperation: devices Ambient intelligence interoperate spontaneously in changing environments, Proactive computing e.g., a device changes its Augmented reality partners as it moves or as the context changes.
PRINCIPLES OF PERVASIVECOMPUTING
CLASSIFICATIONINFRASTRUCTURE SYSTEMSPERSONAL SYSTEMS Attention, Complexity, Privacy, Security, And Extensibility.
EVOLUTION & RELATED FIELDS Two distinct earlier steps in this evolution: DİSTRİBUTED SYSTEMS MOBİLE COMPUTİNG
Examples of Pervasive Computing Technologies
THEMES OF PERVASIVECOMPUTING
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• Examples Meeting capture (scribe at Xerox PARC), Mark Weiser Classroom 2000
CONTEXT-AWARE COMPUTING• Computing services sense aspects of environment (location, user emotion,…) and tailor provided Augmented Reality services• Walk into conference room, my email is projected on a big screen thereEXAMPLES• 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 PERVASIVECOMPUTING
REAL TIME APPLICATIONS SMART CLOTHING ►Conductive textiles and inks print electrically active patterns directly onto fabrics. ►Sensors based on fabric monitor pulse, blood pressure, body temperature. ►Invisible collar microphones ►Game console on the sleeve?
REAL TIME APPLICATIONS INTERACTIVE 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.
REAL TIME APPLICATIONS PILL CAM Miniature camera Diagnostic device It can be swallowed Once swallowed it gives the data about the functioning of the vital organs in our body .
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 ASPECTS Cell phones will ask the Cars will use the Internet to landline phone what its find an open parking space telephone number is and will or the nearest vegetarian forward our calls to it. restaurant inform the owner of the needed service or automatically install the Wrist watches will monitor necessary (software) repair our 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.
CONCLUSION Pervasive computing in an increasingly networked world continues to affect more and more of the worlds 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.Let’s not throw the first stone, but make the first step!
