Covas-Smith, Christine M. and Bell, Herbert H. (2011): Network latency and perceived fidelity of motion in a networked flight simulator. In: Proceedings of the Human Factors and Ergonomics Society 55th Annual Meeting 2011. pp. 1529-1532.

“We investigated the effect of delay in the transmission of position information on the perceived fidelity of motion in networked flight simulation setting. Observers rated perceived fidelity of motion and ability to perform a chase formation flight task for the simulated maneuvers of an F-16 under three conditions of constant network delay (50, 150, 300 ms), three conditions of variable network delay (± 0, 12, 25 ms), and two levels of smoothing, a position correction algorithm (no smoothing, smoothing across 1 sec). We found significant effects of variable delay and smoothing and that the greater contributor to decreased perceived fidelity of motion is variable network delay. Implications of these results will be discussed and suggestions provided as to when algorithms such as smoothing should be enabled.”

Bell, Herbert H. (1995): The Engineering of a Training Network. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 1311-1315.

“This presentation describes the architecture and engineering development of the Multi-Service Distributed Training Testbed (MDT2). It summarizes the basic principles underlying Distributed Interactive Simulation (DIS) and the major components of MDT2. It then discusses the problem of simulator interoperability and describes some of the interoperability problems encountered during in developing MDT2. MDT2 demonstrates that widely dissimilar training devices can be successfully linked to create a virtual testbed for training research.”

Gordon, Sallie E., Babbitt, Bettina A., Bell, Herbert H. and Sorensen, H. Barbara (1994): Development of a Real-Time Simulation with Intelligent Tutoring Capabilities. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 1247-1251.

“Training programs for complex tasks are increasingly using simulations to provide transfer of training to the job environment without incurring high costs of on-the-job training. A second trend in training is toward the use of intelligent tutoring systems (ITSs) to provide individualized feedback to optimize training. Combining simulation with an ITS can be especially beneficial, but use of intelligent tutoring mechanisms such as expert systems is often difficult in a complex, real-time environment. In this paper, we describe the development of a proof-of-concept training program that combines F-16 flight simulation with an embedded real-time intelligent tutoring system. In the simulation, pilots learn the correct use of advanced fire control radar modes to locate and assess multiple enemy formations (search and sort tasks). The expert system monitors pilot behavior and verbal responses as the pilot flies the simulation. At certain critical points, if the pilot's performance has fallen outside of pre-specified parameters of "safe" behavior, the tutoring component stops the simulation and feedback is provided.”

Houck, Michael R., Thomas, Gary S. and Bell, Herbert H. (1989): Training Potential of Multiplayer Air Combat Simulation. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1300-1304.

“The objective of this investigation was to identify air combat mission tasks that could be trained using existing multiship simulator technology. Forty-two mission ready F-15 pilots and 16 tactical air controllers rated their need for additional training on 41 air combat tasks. These pilots and controllers then participated in four days of air combat training using McDonnell Aircraft Company's simulation facility. This training allowed the participants to practice two-ship tactics in an unrestricted combat environment which included multiple air and ground threats, electronic combat, and real-time kill removal. Following training, the participants rated the value of their current unit training and training provided by the multiship simulation. Pilots rated the multiship simulator training superior to their current unit training for 22 of the 41 air combat tasks. Pilots also rated their need for additional training in those 22 combat tasks from "very" to "extremely" desirable. The controllers indicated that all combat tasks were better trained in the multiplayer simulation than in their current unit training program. Interviews and questionnaires also identified a number of strengths and weaknesses of the simulation that provide "lessons learned" for the development and use of future multiplayer air combat simulations.”
