Tactical Tomahawk Weapon Control System v6 Land Attack Combat System Prototype Human-Computer Interface

摘要

The purpose of this document is to outline the human performance evaluation of the FY03 Fleet Operability Test (FLOT) of the Land Attack Combat System (LACS) Human-Computer Interface (HCI) prototype, developed by the Space and Naval Warfare Systems Center, San Diego (SSC San Diego). The goal of this evaluation was to determine the level of performance that can be expected from the Tactical Tomahawk Weapon Control System (TTWCS) given the latest incorporation of human factors engineering principles and task management techniques developed under an Office of Naval Research (ONR) Future Naval Capability (FNC) research and development effort'. It should be stressed that the purposes of this evaluation were to explore the effectiveness of the current TTWCS prototype HCI in supporting performance and to identify any weaknesses in its design that could be addressed during either the ongoing FNC effort or fleet system development. As such, this investigation was not intended to be an experimental comparison. Instead, data were collected under one condition: an operator with prior Tomahawk experience performing a scenario using the prototype llCI. For the scenario, a single operator performed tasking ordinarily executed by multiple operators over a longer time period in less time. Analysis then determined whether the individual operator successfiilly and comfortably completed tasking or was close to being unable to successfiilly accomplish tasking, in terms of workload and awareness of the tactical situation. In support of the general experimental process, control principles of experimental design were followed to minimize differences in testing conditions between operators, and standard ethical procedures to protect human participants were followed.
