Self-Conscious

• Self conscious products exploit their internal knowledge in
better or different ways.
• Smartness can be in learning; applying intelligent algorithms;
and displaying pro-active behavior; artificial intelligence…

User-Conscious

• User Conscious product are able to get insight in the head of
the user. They understand what drives the user and what the
intentions of the user are.
• Smartness is in the ability to react to specific intentions of the
user.

Conscious Conscious

• The product is aware of its environment and the changes in
environmental parameters.
• The product can have an impact on the environment.
• Smartness is in the ability to react to specific environmental
conditions.

Conscious Conscious

• The product is aware of the other products that are part of the
eco-system
• Smartness is in the fact that a group of products is combined
in an intelligent way
• => eco-system infrastructure
