Abstract
We outline the relation of the concept of analytic redundancy to Cognitive Work Analysis and to Ecological Interface Design. Analytic redundancy refers to different ways that system inputs can be related to system outputs so as to retain system objectives, whether for inferring state or exercising control. We extend previous treatments on the concept of analytic redundancy and stress the importance of finding a strong representational formalism if a human operator supported by an EID interface is to provide analytic redundancy and be capable of “finishing the design”. While increasingly straightforward in the visual domain, there are still challenges in the auditory domain.
