Usage-centered design
From Wikipedia, the free encyclopedia
Usage-centered design is an approach to user interface design based on a focus on user intentions and usage patterns. It analyzes users in terms of the roles they play in relation to systems and employs abstract (essential) use cases for task analysis. It derives visual and interaction design from abstract prototypes based on the understanding of user roles and task cases.
Usage-centered design was introduced by Larry Constantine.

[edit] Usage-centered design methods
Usage-centered design is largely based on formal, abstract models such as models of interaction between user roles, UML workflow models and task case and role profiles. Usage-centered design proponents argue for abstract modelling while many designers use realistic personas, scenarios and high-fidelity prototypes.
[edit] Usage-centered design and activity-centered design approach
Usage-centered design share some common ideas with activity-centered design. It is concerned more with the activities of users but not the users per se. In [Constantine, 2006] an integrated framework is presented where the models of Usage-centered design are enriched with concepts from the Activity theory.
