Abstract
A theoretical framework for designing interfaces for complex human-machine
systems is proposed. The framework, called ecological interface design
(EID), is based on the skills, rules, and knowledge taxonomy of cognitive
control. The basic goals of EID are not to force processing to a
higher level than the demands of the task require, and to support
each of the three levels of cognitive control. Thus, an EID interface
should not contribute to the difficulty of the task, and at the same
time, it should support the entire range of activities that operators
will be faced with. Three prescriptive design principles are suggested
to achieve this objective, each directed at supporting a particular
level of cognitive control. Particular attention is paid to presenting
a coherent deductive argument justifying the principles of EID. Support
for the EID framework is discussed. Some issues for future research
are outlined
