Team Trust in Human-Autonomy Teams: Analysis of Crew Communication during Manned-Unmanned Gunnery Operations
Abstract
Verbal communication within Soldier and Marine crews was recorded during the Wingman Joint Capability Technology Demonstrations dry-fire and live-fire manned-unmanned teaming gunnery exercises at Fort Benning, Georgia, in October 2018. Their communication was analyzed to identify and assess possible communication-based metrics of team trust and cohesion. Communication flow in five-person crews was aggregated to reveal the proportion of communication for each sender receiver pair. Findings indicate there were differences in communication patterns between the crews and dry- and live-fire conditions. Aggregate communication flow revealed structural differences in the communication patterns used on-task versus off-task and identified the relative dominance of the commander gunner communication. Relational event models were used to analyze communication-network dynamics. The models revealed patterns of greater centralization and routinization of communication channels during dry-fire scenarios compared with live-fire scenarios. Language-similarity measures were calculated to evaluate the semantic and syntactic synchrony within the language used by crew members. Measures indicated the Soldier crew exhibited greater variability in its linguistic synchrony, whereas the Marine crew exhibited more stability. Overall, findings suggest these approaches can characterize the interaction and coordination patterns of human autonomy crews and may be useful for relating communication to team trust and cohesion.
