Concurrent performance of gunner's and robotics operator's tasks in a multitasking environment.
In this study, we simulated a generic mounted crew station environment and conducted an experiment to examine the workload and performance of the combined position of gunner and robotics operator. Results showed that participants'gunnery task performances degraded significantly when he had to concur...

Results showed that participants'gunnery task performances degraded significantly when he had to concurrently monitor, manage, or teleoperate an unmanned ground vehicle compared to the gunnery single task condition. For the robotics tasks, participants had the lowest performance when using the semi-autonomous robot, indicating overreliance on the aided target recognition capabilities available when task load was heavy (i.e., concurrent performance of the gunnery task). Participants' perceived workload increased consistently as the concurrent task conditions became more challenging. Individual difference factors such as spatial ability and perceived attentional control were found to correlate significantly with some of the performance measures. Implications for military personnel selection were discussed. pubtype: Academic Journal doctype: pictorial research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
