Effects of a Network-Centric Multi-Modal Communication Tool on a Communication Monitoring Task.

摘要

Multi-Modal Communnications tool suite was developed to better equip C2 operators to manage the high workload and complex communication environments in which they work. This integrated system captures, diplays, records and archives radio and text-based chat communications. This study examined the performance associated with monitoring communication channels, with access to different tools. Operators monitored and responded to the occurrence of critical phrases presented during a 27-min communication monitoring task. Communication performance was analyzed in regard to message detection, response accuracy, and time. Data showed that MMC provides a balance between the speed of radio listening and the accuracy and data-capturing capabilities of chat displays. MMC can be a beneficial tool to operators in its ability to increase intelligibly, while providing a persistent, searchable display that reduces perceived mental workload.
