Interface Controls Reduction is the design task of generating simplified interface controls for setting a larger, more complex set of controls. We explore three different empirical approaches to the task: preset sharing, point clustering, and principal component analysis. All three draw on the experience of lead users to recommend simplified controls for others. A case study where they were applied as part of an iterative development cycle with hundreds of users reveals the advantages and challenges of each approach.
