A Multiple Processing Resource Explanation of the Subjective Dimensions of Operator Workload
Multiple measures of operator workload may dissociate, or fail to agree, for a given task. The goal of this study was to determine how workload as indexed by attentional resource demand could explain the attendant variance in a second measure of workload, subjective ratings. A multiple structure …

Small Unmanned Aircraft Systems: Operator Workload and Situation Awareness Utilizing First Person View Techniques
… sUAS within the NAS would have an effect on the operator’s workload and if FPV techniques affect the operator’s Level 1 situation awareness (SA). More specifically, this study examined sUAS operator workload and Level 1 SA while using three visual acuity techniques: visual-line-of-sight, FPV with …

The Impact Of Mental Transformation Training Across Levels Of Automation On Spatial Awareness In Human-robot Interaction
One of the problems affecting robot operators' spatial awareness involves their ability to infer a robot's location based on the views from on-board cameras and other electro-optic systems. To understand the vehicle's location, operators typically need to translate images from a vehicle's camera …
