DCA build and test a wide variety of ergonomic models and rigs at all stages of the design and development process. At one extreme these rigs can be small, handheld block models used to evaluate product form and the operation of user controls and displays. Alternatively, they may be representative of larger industrial equipment and used to check man machine interfaces, user comfort, and service staff access.

At the upper end of the spectrum are spatially representative, full-scale, transportation or architectural interior mock-ups used to monitor people flows, sightlines and access.
