The ability to design and assess new control schemes is integral to the development of any human operated vehicle. Design and placement of controls and gauges effect operator effort, operator visibility, and vehicle aesthetics. By minimizing operator effort designers can insure that productivity is increased for any vehicle. Increased operator visibility helps to make the operation of the vehicle safer. Improved vehicle aesthetics increases customer acceptance which ultimately leads to greater sales. This paper outlines a qualitative method to quickly change and evaluate prototype controls and their placement before they are ever built.
