Integrating Intelligent Structured Training with a Virtual Dismounted Environment.

摘要

The advancing state of the art in dismounted embedded training makes use of helmet-mounted displays, manwearable computers, and other immersive hardware to construct increasingly engaging environments. Within such a frame work, structured training methods provide a means to achieve learning objectives and concept retention, with minimal instructor involvement. Intelligent structured training applies real-time automated evaluation and feedback methods based on Intelligent Tutoring Systems (ITS) techniques. This paper reviews results from the integration of an Intelligent Structured Trainer with the embedded Virtual Warrior Soldier prototype developed for the Army RDECOM Simulation and Training Technology Center. Army subject matter experts defined dismounted training objectives and specific requirements for integrated evaluation mechanisms. The paper discusses three areas of research results, both in terms of direct research findings and also how these findings can be applied for future work. First, the effort identified the nature of the data that an integrated structured trainer consumes in order to generate useful real- time feedback for dismounted Soldiers. This data includes not only state information direct from the simulation, but also data reflecting Soldier actions in the primary interface and secondary Command and Control interfaces. Data categories can be generalized and catalogued for future related training efforts. The second research outcome is an analysis of scenario authoring requirements, in terms of SAF 'semi-automated forces' performance, terrain database accuracy and consistency, data protocols and availability, and the authoring process itself. Third, user feedback collected from initial experiments with human Participants provide several indicators for the areas of greatest fit or friction between the dismounted training objectives and a structured training approach.
