Apply HFACS to accident investigation system interface design

Abstract

This study proposes a new methodology for conducting analyses using new user interfaces based on Human Factors Analysis and Classification System (HFACS). The objective of this research is to evaluate the performance of this new methodology for its use by people who are not ergonomic experts. We developed two accident investigation system interface alternatives which are based on the HFACS model. The participants were asked to conduct analysis with assistance of both alternatives in four cases. The results indicate both alternatives could be considered as good appliances to assist those who have no background knowledge about HFACS. The correct rates have significant difference between the two alternatives in one case, which is related to risky factors of supervisory and upper-level management. This finding has important implications that people who are not familiar with HFACS can regularly provide accurate analyses with the assistance of our investigation system interface.
