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?
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
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
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.
