1. PERVASIVE COMPUTING

2. 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.

3. PERVASIVE COMPUTING Pervasive 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: , Personal Information Manager (PIM); Inter-Intranet; Public Services.

4. Contd… Ubiquitous computing Calm technology Things that think
Other terms for pervasive computing:
Ubiquitous computing
Calm technology
Things that think
Everyware
Pervasive internet
Ambient intelligence
Proactive computing
Augmented 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.

7. EVOLUTION & RELATED FIELDS
Two distinct earlier steps in this evolution:
DİSTRİBUTED SYSTEMS
MOBİLE COMPUTİNG

8. HUMAN COMPUTER INTERACTİON ARTİFİCİAL INTELLİGENCE
RELATED FIELDS
SENSOR NETWORKS
It consists of computing devices equipped with sensors, a wireless radio, a processor, and a power source.
Physical environment (e.g., environmental pollutions, wildlife).
HUMAN COMPUTER INTERACTİON
It is the study of interaction between people (users) and computers.
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.
ARTİFİCİAL INTELLİGENCE
“Artificial Intelligence is a branch of science which deals with helping machines find solutions to complex problems in a more human-like fashion”.
AI is generally associated with Computer Science, but it has many important links with other fields such a Maths, Psychology, Cognition, Biology and Philosophy, among many others.

9. Examples of Pervasive Computing Technologies
Advanced high bandwidth networking services
Networked devices, sensors, instruments, interfaces
Information and computational resources
Telecommunication including global wireless voice and data broadband networks
Human-machine interaction technologies
Software "agent" technologies

10. THEMES OF PERVASIVE COMPUTING
Automated capture
Context-aware
Ubiquitous services
Natural/Implicit interfaces

11. AUTOMATED CAPTURE Motivation Examples
Record-taking is hard
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
LIVE BOARDS

12. CONTEXT-AWARE COMPUTING
Computing services sense aspects of environment (location, user emotion,…) and tailor provided services
Walk into conference room, my 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
Augmented Reality

Home interaction

16. 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?

17. 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.

18. 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 .

19. 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.

20. FUTURE ASPECTS
Cell 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.

21. 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!
