And Performance

How team cognition is conceptualized has evolved rapidly in the last decade with the emerging use of a systems approach, moving the focus from the cognition residing in the heads of individuals, to that distributed across the team. This is referred to as ‘distributed cognition’. Increasingly, network approaches are being explored in attempts to model team distributed cognition. The specific domain of interest in the present study is the sociotechnical system within a maritime control room. This comprises human, machine and software agents interacting to interpret sensor data in order to develop a timely and accurate picture of surrounding contacts at sea. To achieve the goal, information is shared or integrated across the maritime control room consoles. The aim of this study was to develop and apply a suite of workload, situation awareness and team performance measures, including network analysis techniques, to examine how the distributed cognition of a team might change as a function of console configuration and information integration within a control room, and how these changes, if any, impact overall team performance. Sixteen teams of six novices conducted two one-hour scenarios operating generic maritime control room positions. Each team completed a one-hour simulation in each of two console configuration layouts with the order counter-balanced (within-subject design). Half the teams conducted the two scenarios in a high integration condition, and half in a low integration condition (between-subjects). The human machine interface (HMI) designs for the high integration condition emerged from a series of task analyses and user-centered design workshops. The emergent cognitively –oriented HMI designs are based on the assumption that each console can freely share information with other consoles. To create an analogue of current, less-integrated, and more stove-piped systems, a low integration condition was created where not all information was shared across consoles, but instead was shared verbally by console operators. Contacts detected at sea were introduced into the simulation and the team’s task was to assess, report and derive a solution (location, course, and speed) for each detected contact. Individual situation awareness was measured through the Situation Present Assessment Method (SPAM) and individual workload through the Air Traffic Workload Indicator Task (ATWIT). Team interaction from the scenarios were video recorded and we applied the Event Analysis of Systemic Teamwork (EAST) approach to examine the task, social and information networks which emerged. Team performance was measured as the accuracy and timeliness of the solutions We found higher information integration lowered average team workload, and improved average team situation awareness and team performance (faster solutions and a more accurate tactical picture). We found no impact of console configuration on team performance or any other dependent measure. The EAST method uncovered patterns in the network analysis that are potentially explanatory for the team workload, situation awareness and performance findings as a function of the information integration manipulation. This experiment showed that there can be reductions in workload, and improvements to situation awareness and performance when information is shared between consoles in a considered design. This has implications for HMI design within a team setting. The set of diagnostic metrics developed were largely effective in examining teamwork and team performance. Acknowledgements.

Operator Workload

Objective Examine the extent to which increasing information integration across displays in a simulated submarine command and control room can reduce operator workload, improve operator situation awareness, and improve team performance. Background In control rooms, the volume and number of sources of information are increasing, with the potential to overwhelm operator cognitive capacity. It is proposed that by distributing information to maximize relevance to each operator role (increasing information integration), it is possible to not only reduce operator workload but also improve situation awareness and team performance. Method Sixteen teams of six novice participants were trained to work together to combine data from multiple sensor displays to build a tactical picture of surrounding contacts at sea. The extent that data from one display were available to operators at other displays was manipulated (information integration) between teams. Team performance was assessed as the accuracy of the generated tactical picture. Results Teams built a more accurate tactical picture, and individual team members had better situation awareness and lower workload, when provided with high compared with low information integration. Conclusion A human-centered design approach to integrating information in command and control settings can result in lower workload, and enhanced situation awareness and team performance. Application The design of modern command and control rooms, in which operators must fuse increasing volumes of complex data from displays, may benefit from higher information integration based on a human-centered design philosophy, and a fundamental understanding of the cognitive work that is carried out by operators.

Information integration is great for military operations because the range of pertinent information sources is significantly distinct and dynamic. This article develops an intelligent knowledge treasure comprised of military resource ontology and procedures, as a learning model for better interoperability of heterogeneous resources of the Indian military. This model can interpret and learn the context of military information automatically, thereby facilitating the military commanders with decision making in several operations, such as command and control, teaching and training, military coalition, situation awareness and many more. To design the military resource ontology, this article specifies the core concepts of the ontology based on terms derived from heterogeneous resources. WWW standard ontology language, OWL has been used to codify the ontology. This article develops an intelligent tool—“QueryOnto”—as an interface to the military resource ontology that provides a commander decision support service and demonstrates how to apply the military ontology in practice. The developed ontology has been verified and validated with the best known approaches and metrics available. The presented model is helpful for military commanders to train their juniors in a systematic way and will provide an efficient web-based learning of different military tasks in future.
