Paper about creativity of everyday design

This is an interesting, compact paper about the idea of designing systems in use, that gives you a good opening for great and attractive discussions.
The authors in this article are looking at the sustainability in interaction design by reframing concepts of the user identity and the use. They are suggesting a new identity for the creative user and an alternative view of end-users, and taking up everyday design, design artifacts through design-in-use in ways that lead to the sustainable actions of renewal, reuse and invention. The authors advocate that designers reconsider the life cycle of artifacts to include design-in-use as a critical factor:

• Design-in-use is highly creative making a user unpredictable in the best sense of the word.

• Design artifacts are resources for further creativity.

• Design-in-use qualities emerge over time.
