A Procedure for the Design of Multifunction Switching Controls,
Abstract
The handbook provides an independently usable, step-by-step procedure for the design of a multifunction switching control (MSC). An MSC is a matrix of switches which address a computer or other logic interface. This interface, in turn, addresses the system or subsystem to be controlled. Each switch in the matrix may have any number of different functions, its function at any given time determined by system state variables and the programming of the logic interface. The procedure itself is designed to effect the optimum trade between the number of switching controls required and associated operator workload. A conceptual design is developed first, based solely on system (and operator) requirements, to permit a quantitatively assessment of the effect of hardware constraints on the optimum design. Implementation constraints are subsequently introduced and methods of dealing with such constraints described. (Modified author abstract)
