Eye gaze movement studies of control room operators: A novel approach to improve process safety

摘要: Abstract Process industries continue to suffer from accidents despite significant regulatory intervention since the mid-1980s. Human error is widely considered be major cause for most today. Detailed analysis of various incidents indicates that reduced staffing levels in control rooms and inadequate operator training with complex automation strategies as common reasons human errors. Therefore, there a need develop deeper understanding errors well prevent them. However, similar hardware failures, traditionally has been quantified using likelihood approaches; this viewpoint abnegates role cognitive abilities operators. Recent studies other safety critical domains (aviation, health-care) show operator's level situation awareness inferred by eye tracking good online indicator error. In work, novel attempt made understand behavior typical chemical plant room information obtained tracker. Experimental conducted on 72 participants reveal fixation patterns contain signatures about operators learning at situations. Implications these findings process operations them are discussed.
