ABSTRACT
A systematic approach to the design space of instrument display components is described based on a semiotic extension of Cognitive Systems Engineering (CSE). events that can occur within the larger system, for which the automation systems and interfaces have been designed. The operators (users) consequently have to adapt tasks and procedures and/or tailor the systems and interfaces in order to compensate for deficiencies in the design relative to the actual situations and contexts of use. This tailoring includes ad-hoc modifications to instrument interfaces and display devices, but safe and efficient tailoring is usually not supported systematically through the design of flexible interface components. There are two main strategies for interface-supported flexibility: adaptation and tailoring. Ecological Interface Design, the main approach to representation design within CSE, has been proposed as a design solution for complex work domains.
