Chapter Six Real-Time Expert System Interfaces, Cognitive Processes, and Task Performance
Leonard Adelman Marvin S. Cohen Terry A. Bresnick James O. Chinnis Kathryn B. Laskey
This chapter reports on an experiment that investigated the effect of different real-time expert system interfaces on operators’ cognitive processes and performance. The results supported the principle that a real-time expert system’s interface should focus operators’ attention to where it is required most. However, following this principle resulted in unanticipated consequences. In particular, it led to inferior performance for less critical, yet important cases requiring operators’ attention. For such cases, operators performed better with an interface that let them ...
