With the ultimate purpose of assessing risk within augmented reality-equipped socio-technical systems, in our previous work, we systematically organized and extended state-ofthe- art taxonomies of human failures to include the failures related to the extended capabilities enabled by AR technologies. The result of our organization and extension was presented in form of a feature diagram. Current state-of-the-art taxonomies of faults leading to human failures do not consider augmented reality effects and the new types of faults leading to human failures. Thus, in this paper, we develop our previous work further and review state-of-the-art taxonomies of faults leading to human failures in order to: 1) organize them systematically, and 2) include the new faults, which might be due to AR. Coherently with what done previously, we use a feature diagram to represent the commonalities and variabilities of the different taxonomies and we introduce new features to represent the new AR-caused faults. Finally, an AR-equipped socio-technical system is presented and used to discuss about the usefulness of our taxonomy.
