While many different task analysis techniques exist to suit the different design requirements in systems our primary focus here is on techniques that help in designing the interface. The key issues involved in designing a human interface with automated equipment are assessing what will be needed to do a job the types of information that human operators will need to understand the current system status and requirements the types of output that human operators will have to make to control the system and deciding how this will be provided. .
