Expert System Advice: How Should It be Given

摘要

The objective of this research was to investigate different alternatives for pilot-computer interaction with a simulated expert system. Three methods of advice presentation were investigated -- automatic, subject requested, and a combination of the two. Also, three experience levels of the subjects were examined -- novice, intermediate, and expert. The dependent variables were total score for successful missions completed during the experimental session and average time to complete a successful mission. The analysis of the data revealed that the automatic condition was the best overall method for advice presentation (p.<1) and the experience level of the subjects was not a significant factor.
