Abstract
This document contains display requirements for Littoral Combat Ship (LCS) control
station displays to be used by unmanned vehicle units in support of heterogeneous
unmanned vehicle missions (such as Special Operations Force (SOF) insertion). The
method used for generating the requirements was that of a Hybrid Cognitive Task
Analysis (CTA)1 which entails describing a scenario overview of a representative
mission, generating event flow diagrams, and depicting decision ladders for the key
decisions identified in the event flow diagrams. These steps are then used together to
generate an informational requirements summary which includes the situational
awareness requirements that are derived from the event flow and display requirements of
the decision ladders. This method was developed in Phase I of the PUMA (Plan
Understanding for Mixed-initiative control of Autonomous systems) project2. In PUMA
I, the mission scenario primarily consisted of Intelligence, Surveillance and
Reconnaissance (ISR) tasks. For PUMA II, the scenario has been expanded to include
Mine Counter Measures (MCM), Harbor Bottom Image-Mapping (HBI), and Anti-
Terrorism / Force Protection (AT/FP) mission types. There is a specific emphasis on the
MCM and ISR missions to highlight the informational requirement differences between
the two task types. This document incorporates the expanded vehicle and mission type
heterogeneities that are present in PUMA II in order to develop a cohesive set of
informational requirements necessary for such a complex mission.
