Response Surface Methodology as a Manipulator of Complex Task Difficulty

Abstract

Applications of Central-Composite Designs (CCD) in human factors research are reviewed briefly. A recent application of the CCD to the manipulation of task variables is discussed. The use of this approach in the evaluation of a computer-generated aircraft area navigation control-display system is outlined, showing how this approach can be used to evaluate system/operator performance systematically and economically across a wide range of task and environmental variables.
