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 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.

 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 PERVASIVE
COMPUTING
CLASSIFICATION
INFRASTRUCTURE
 SYSTEMS
PERSONAL SYSTEMS
  Attention,
  Complexity,
  Privacy,
  Security, And
  Extensibility.
EVOLUTION & RELATED FIELDS

 Two distinct earlier
 steps in this
 evolution:
  DİSTRİBUTED
   SYSTEMS
  MOBİLE
   COMPUTİNG
RELATED FIELDS
Examples of Pervasive Computing Technologies
THEMES OF PERVASIVE
COMPUTING
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
  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
BENEFITS OF PERVASIVE
COMPUTING
TECHNOLOGY AND APPLICATIONS

 Information access            Mobility and networking
 Text retrieval                Device discovery
 Multimedia document           Wireless protocols
    retrieval                   Security
   Automatic indexing          Voice and video over IP
   Pervasive devices           Perceptive interfaces
   Palm top computers          Biometric person ID
   Smart badges                Speech recognition
   Electronic books            Gesture recognition
   User sensitive devices
USES OF PERVASIVE
COMPUTING
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 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.
Let’s not throw the first stone, but make the first step!
