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 and Lucy Lockwood. The primary reference is their book.

Famous quotes containing the word design:
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
