Performance, Workload, and Eye Movement Activity 951570
In this study four experiments were conducted aimed at creating an objective physiologic metric of operator workload by comparing subjective and objective measures of performance. Thirty-four participants completed a series of computer-based tasks and the NASA-TLX workload metric. Neuroelectric eye movement indices (e.g., blink, velocity) were then collected using a subset of these tasks. In general, the results were very good. Eye movement indices during performance on the computer-based tasks showed some statistical significance. A current study is underway to further examine eye movement indices as an objective physiologic metric.
