  1. Pervasive Computing Ian Christe

  2. Key Definitions • Pervasive - Spreading widely throughout an area or a group of people. • Ubiquitous - Present, appearing, or found everywhere.

  3. What is Pervasive Computing? Computing in a world with computers infiltrating every aspect of our lives.

  4. Relation to TraditionalComputing • Main Frames • One computer many people • Most people could not see this future • Personal Computers • Why would anyone have more than one computer?

  5. Relation to Mobile and Ubiquitous Computing • Now we have multiple computers • Desktop, Laptop, tablet, Smart Phone • Most have 2 or more • What is Next? • Computers everywhere • Subconscious interactions

  6. Founders IBM coined the term Pervasive Computing in the late 80’s Xerox came up with Ubiquitous Computing at the same time

  7. Xerox's PARC • Developed tablets, smart boards, and PDAs • All interconnected • Ad from 1991

  8. Why do we want it? • Simplifies life • Gives us more out of life • Information • Less stress • Less to think about

  9. How does it affect us today? • Cars • Phones • School • And more!

  10. Examples • Unlock and start a car with keys in your pocket. • Seamless • No thought needed • Google Glasses • Possible improvement over smart phone. • Convenient.

  11. What will it take? • Contextually aware software • Ways of gathering data on surroundings • Networking many small computing devices together • Hardware

  12. Contextually aware • Software must learn about the surroundings • Must be able to learn about the user • Must be able to predict the users needs

  13. Methods of data gathering • GPS • Microphone • Accelerometer • Camera • Sensors of many types

  14. Networking • Sensor Networks • RFID Tags • Embedded Systems

  15. Hardware • Cheap • Small • Long battery life • Efficient wireless connectivity

  16. Challenges • Sensing the environment • Interpreting human actions • Embedding all of this technology seamlessly

  17. How will it affect us tomorrow? • Passively or subconsciously interact • Our backpack will remind us that we are forgetting our notebook. • Rooms will adjust to us entering or leaving • Lighting • Music • Temperature

  18. How will it affect us tomorrow? • Every aspect of our lives could potentially be affected. • Monitoring health, nutrition, sleep quality • Monitoring your house • When to go shopping and what to get • Tracking water and light levels of potted plants • Going out to eat • Glass detects need for refill • No need for waiter for ordering

  19. Augmented Reality • Digital overlay on a display • Provides an enhanced experience • Information • Directions • Blueprints • Games • Spotlight objects

  20. Security • Computers will know more about you • More than just browsing history • Locations • Personal preferences about everything • Laws will be playing catch up • What will happen in the meantime? • How do we protect all of these networks and keep them efficient at the same time?

  21. Security • How will the ability to track a persons life change the way people act? • How will this information be kept safe?

  22. Conclusions • We are moving in the direction of Pervasive/ Ubiquitous Computing. • In limited areas we are already there. • We will see how far it goes.
