Make the Product more 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…

Make the Product more 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.

Make the Product more Ambient-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.

Make the Product more Eco- System 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
Make the Product more Eco-System Conscious
