| Popis: | In current military operations, a team of human operators, often distributed across multiple locations, is required to manage even a single Unmanned Vehicle (UxV). For future multi-UxV control, effective dynamic task sharing strategies – the ability to quickly re-assign tasks and responsibilities between operators or between operators and autonomous systems - will vastly improve team coordination. However, for task hand-off to be executed effectively, the task assignee needs to be quickly brought up to speed with sufficient situation awareness to effectively handle their new tasking. We have implemented a system, called Computational Situation Awareness (CSA), that encodes the awareness maintenance process into the control station itself. CSA generates a computational “mental” model of an expert’s SA and maintains multi-level awareness of the mission and state of the unmanned systems. This allows the system to predict information requirements and drive cueing and other mitigations for individuals and across the team. By tracking user tasks and system state related to those tasks, CSA builds an understanding of the task’s progress thus enabling it to better determine what information the user needs to maintain task relevant SA without bogging them down. By encoding workload assessment and situation awareness into the operator control station itself, the control station becomes a partner with the operator (or team of operators) in making sense of the data. This enables it to manage task sharing and offloading and share information in terms that aids rather than distracts, thus improving each operator’s mission effectiveness. |
