PERVASIVE COMPUTINGIan 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

6

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

7

FOUNDERS

IBM coined the term Pervasive Computing in the late 80’s

Xerox came up with Ubiquitous Computing at the same time

8

XEROX'S PARC

Developed tablets, smart boards, and PDAs All interconnected Ad from 1991

9

WHY DO WE WANT IT?

Simplifies life Gives us more out of life

Information Less stress Less to think about

10

HOW DOES IT AFFECT US TODAY?

Cars Phones School And more!

11

EXAMPLES Unlock and start a car with keys in your

pocket. Seamless No thought needed

Google Glasses Possible improvement

over smart phone. Convenient.

12

WHAT WILL IT TAKE?

Contextually aware software Ways of gathering data on surroundings Networking many small computing devices

together Hardware

13

CONTEXTUALLY AWARE

Software must learn about the surroundings Must be able to learn about the user Must be able to predict the users needs

14

METHODS OF DATA GATHERING

GPS Microphone Accelerometer Camera Sensors of many types

15

NETWORKING

Sensor Networks RFID Tags Embedded Systems

16

HARDWARE

Cheap Small Long battery life Efficient wireless

connectivity

17

CHALLENGES

Sensing the environment Interpreting human actions Embedding all of this technology seamlessly

18

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

19

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

20

AUGMENTED REALITY

Digital overlay on a display Provides an enhanced experience

Information Directions Blueprints Games Spotlight objects

21

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?

22

SECURITY

How will the ability to track a persons life change the way people act?

How will this information be kept safe?

23

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.
