This report describes progress on work centered on the demonstration of a system of integrated on-line adaptive user models designed to automatically select and pace information in a simulated command, control, and communication (C3) system. The report includes: (1) a human-factors based rationale for improving information flow in C3 systems; (2) a description of modifications made to the Tactical and Negotiations Game (TNG) scenario to create a C3 decision simulation in which automatic selection and pacing of information can be realistically accomplished; (3) the conceptual specification of a real-time, computer-based model for automatically adapting message pacing rate to the information processing and decision making capabilities of an individual operator; (4) an overview of the software configuration being implemented to support the system. The next phase of work will focus on the system implementation of the newly developed configuration of information selection and pacing models.
