A goal of this effort is to improve the realism of computer-generated force CGF entities in constructive simulations. Currently, CGF entity behavior is very predictable and unrealistic with respect to the natural variability with which humans perform given varying amounts of aptitude, training, and environmental stressors to which they would be exposed on a real battlefield.

Current CGFs behave as perfectly trained troops, their ability to perform missions to do not vary. This is an inaccurate portrayal of human performance. If the military cannot model human factors, such as training and physiological stressors in ADS, they cannot perform trade-off analyses.

An input routine includes receiving environment data and/or data from a subject within the environment, eg, true position and orientation of the environment and/or subject. A vestibular attitude calculator computes perceived subject attitude for environment data elements, and may compute a Washout value. A vestibular illusion routine calculates the probability of a vestibular illusion.

A key decision made at the highest levels of any military is the trade-off between allocating resources to system acquisition versus allocating resources to maintain force readiness through training. Advanced Distributed Simulations (ADS) provide a mechanism for tactical combat training through man-in-the-loop simulators and Computer Generated Forces (CGF).

Display features were designed to address some of the challenges facing robotic operators–reconciling views from different sources, understanding teammate location and orientation, and maintaining spatial awareness of the unmanned vehicle location in relation to mission-relevant landmarks. We added information about orientation and history to teammate ...

This study looked at different training approaches to make better use of simulation as a first training step. When transferring to a live environment, the operators could be grouped into two categories according to whether they passed live training criteria or not. There were clear performance differences between these groups. The group that failed to pass criteria had poorer ...

Color versus grayscale imagery was manipulated. Participants themselves traded off resolution and frame rate settings. Participants minimized switching between resolution/frame rate settings and tended to use settings with high resolution/low frame rate. Courses completed with the highest resolution (and lowest frame rate) had the fastest target identification times, but no ...

An unmanned vehicle (UV) operator used a UV to scope out safe routes and enemy locations and used that information to help a Soldier conduct a rescue mission. There were four communication methods: visual, verbal, real-time verbal plus visual (VPV), and delayed VPV. We manipulated who was in command to see the impact on both pushed and pulled information. Results showed advantages of ...

Two game-based experiments were conducted in which teams conducted a time-limited “Black Hawk Down” rescue mission with and without UV-provided information. When UV information was available, it was relayed between team members in face-to-face communication or remotely, with or without electronic maps, and with or without video ...

Its cost to the US military is over $300 million per year, with comparable costs to US civil aviation. Due to significantly increased research over the past decade, some progress is being made in helping pilots avoid SD's adverse consequences (ie, mishaps, incidents, or accidents). We used a multi-sensory model-based approach to intelligently trigger SD countermeasures. Results for two simulated and one actual SD event were very promising, and indicate that ...

This study however, investigated how to best support effective communication between the operator monitoring a UV and the Soldier in the field using that information to complete a mission. Several questions arise: Does the operator need to be co-located with Soldiers in the field or can he or she be in a more secure rearward location?
