| 摘要： | The results of eight experiments and a meta-analysis are summarized that address three general areas of human-system interaction within the context of a UAV simulation: (1) In examining and modeling the effects of different workload mitigation techniques, regarding automation and multiple resources, we conclude that single channel theory is inadequate to fully model these effects, and that one pilot flying two independent UAVs will sacrifice performance on secondary surveillance tasks, even with perfect automation; (2) In examining the consequences of imperfect automation, we find that such imperfection (unreliability) effects have differential impact on performance depending on the nature of the automation, being less severe for an imperfect autopilot than for imperfect diagnosis. We reach a general conclusion that imperfect automation is acceptable, but that reliabilities less than 0.75 are worse than no automation at all; and (3) We examine the consequences of adjusting the alert threshold in diagnostic automation, trading off automation misses for false alarms, and interpret our data in terms of constructs of automation reliance and compliance. Based on the data from these experiments, the preliminary foundation of a computational model of UAV workload is provided. / NOTE: Final technical rept. / Supplementary Notes: Prepared in cooperation with Micro Analysis and Design, Boulder, CO.
