Abstract: A method for designing a human interface of a system includes establishing guidelines for avoiding sensory overload conditions of a human interacting with the system. The method also includes identifying an event associated with the system producing a potential sensory overload condition. The method further includes generating a human interface design solution based on the guidelines for modifying an operation of the system to help alleviate the potential sensory overload condition associated with the event. A prediction of a performance capability of a human subject interacting with the system may be made by determining a first parameter indicative of an intelligence of a human subject, determining a second parameter indicative of a multiple sensory input memory capacity of the human subject, and determining a third parameter indicative of an interactive monitoring capacity of the human subject and then using the parameters to generate an overall parameter indicative of a performance capacity.
