| 摘要： | The original 2000 AMBR project sought to evaluate how well four human performance models simulated behavior of human participants. Participants and models completed a modified version of an air traffic control task and were compared on the dimensions of performance, reaction time, and subjective workload ratings. The current study replicated the human performance findings of the previous phase of AMBR and added eye tracking analyses to enhance understanding of participants' behavior and to compare NASA TLX workload ratings with ACT-R workload predictions and ICA estimates. Examination of gaze position and patterns of eye movement provided evidence that participants adopted different visual strategies to complete the task in different display conditions and at different levels of demand. Evaluation of workload measures revealed that the three workload measures analyzed seemed to be estimating different facets of the broad concept of workload. Applicability of eye tracking analyses to understanding cognitive workload and augmenting cognitive models is discussed. |
