Specifies general principles to be followed when designing displays and control actuators on machinery to minimize errors on the part of the operator and to ensure an efficient interaction between the operator and equipment.

This Standard specifies general principles for human interaction with displays and control actuators, to minimize operator errors and to ensure an efficient interaction between the operator and the equipment. It is particularly important to observe these principles when an operator error may lead to injury or damage to health. The Standard applies to the design of displays and control actuators on machinery.
