Relationships 

Building engaging, rewarding, active partnerships between people and products by ensuring participation through creative activities. This allows users to become producers, not observers of their interaction, which can also be achieved by letting the user reconfigure the product or learn a new skill or acquire knowledge through using it. And, designing in mechanisms that encourages users to care, tend to and maintain the product building a relationship of mutual altruism. Or providing moments to create a ritual or habit with the product forming a relationship of stability and reliability. Engendering a feeling of control, a sense of mastery through the object, either through intimate knowledge of the product and its inner workings or the ability to use it well.
