Usage-centered design is an approach to
user interface designbased 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 [See Constantine (1995) and Constantine and Lockwood (2001)] for task analysis. It derives visual and interaction designfrom abstract prototypes based on the understanding of user roles and task cases.
Usage-centered design was introduced by
Larry Constantineand Lucy Lockwood. The primary reference is their book. [Constantine and Lockwood (1999); see also Constantine (1996)]
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 caseand role profiles.Usage-centered design proponents argue for abstract modelling while many designers use realistic personas, scenarios and high-fidelity prototypes. The techniques been applied with particular success in complex software projects, some of which have been reported in case studies. [See, for example, Windl (2002) and Strope (2003)]
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.
