Smart Environments

Both generate largeamounts of data

Both need:

• data mining• prediction• classification / identification

What Is a Smart Environment?

An environment able to acquire and apply knowledge about the resident and the physical surroundings to improve the resident’s experience.

Imagine…

Face recognition, automated door entry

Smart sprinklers

Lighting control

Door/lock controllers,Surveillance system

Robot vacuum cleaner

Robot lawnmower

Intelligent appliancesClimate control

Automated blinds

Remote site monitoring and control

What Good Is a Smart Environment?

• Comfort and Productivity

• Health and Safety

• Energy and Sustainability

Page 6: January 20081 Smart Environments: Artificial Intelligence in the Home and Beyond Diane J. Cook cook@eecs.wsu.edu cook.

Our Initial Hypothesis

Resident interactions with smart environments can be automatedby analyzing and predicting resident behavior and using the informationto learn an automation model.

• If we can keep 10% of population home 2 years longer, we will save Washington State $341 million/year

• $15 billion/year nationally

Page 21: January 20081 Smart Environments: Artificial Intelligence in the Home and Beyond Diane J. Cook cook@eecs.wsu.edu cook.

Mission

• Our vision is to keep older adults functioning independently in their own homes as long as possible.

• Our method integrates artificial intelligence, machine learning, and pervasive computing technologies into their everyday environments, turning them into smart environments.
