Figure 3.
The heat map compares estimated percentages of human error reduction achieved by different smart technologies across H F A C S error tiers. The x-axis lists unsafe acts, preconditions for unsafe acts, unsafe supervision, and organisational influences, while the y-axis lists augmented reality, artificial intelligence, radio-frequency identification tool tracking, digital twins, and wearables or sensors. Percentage ranges displayed within the cells indicate estimated reductions in human error. Augmented reality shows reductions of 20 percent to 35 percent for unsafe acts, artificial intelligence shows reductions of 5 percent to 10 percent for unsafe acts and 20 percent to 35 percent for preconditions for unsafe acts, radio-frequency identification tool tracking shows reductions of 20 percent to 35 percent for unsafe supervision and 10 percent to 20 percent for organisational influences, digital twins show reductions of 20 percent to 35 percent for organisational influences, and wearables or sensors show reductions of 10 percent to 20 percent for preconditions for unsafe acts.Estimated ΔHEP (%) by smart technology and HFACS tier (bounded ranges)
