Research at the Air Force Research Laboratory has focused on determining the value of combining computer-generated information with live camera video presented on an unmanned air vehicle (UAV) station display. In a previous study, a picture-in-picture (PIP) concept (where video imagery is surrounded by synthetic-generated terrain imagery, increasing the operator's instantaneous field-of-view) was found to reduce landmark search time and enhance operator situation awareness. The present study examined whether PIP display size and symbology overlay registration error impacts performance. Results confirmed that performance on a landmark search task is better when a PIP display was used, particularly with the more compressed video imagery, reducing average designation time by 60%. Also, the registration error between the virtual flags and landmarks was less critical with the PIP capability enabled. This research has potential application to a variety of teleoperated control applications.

Team Situation Awareness

A coordination-based measure of team situation awareness is presented and contrasted with knowledge-based measurement. The measure is applied to team awareness of a communication channel failure (glitch) during a simulated unmanned air vehicle reconnaissance experiment. Experimental results are reported, including the findings that not all team members should be identically aware of the glitch and that appropriate levels of coordination are an important precursor of team situation awareness. The results are discussed in terms of the application of coordination metrics to support the understanding of team situation awareness. The use of team coordination as a low-dimension variable of team functionality is scalable over a variety of team sizes and expertise distributions.

Simulation approaches generally fall into two categories: discrete time or discrete event. For military modeling and simulation needs, the two approaches typically align with virtual simulation, which implies human interaction with the simulation program, and constructive simulation, which implies no human interaction. The Air Force Research Laboratory develops and distributes AFSIM (Advanced Framework for Simulation, Integration, and Modeling) to a user community that uses both virtual and constructive simulation. This paper documents the software design and primary algorithms that provide AFSIM’s support for both modes, which is termed a hybrid simulation.

Clutter problem of modern cockpit displays can occur frequently due to a large amount of information. So, decluttering less important information is required to minimize search time to find target information and prevent human error in interpreting display information. This study is to compare human search performance by visual complexity levels and decluttering methods of cockpit displays. Visual complexity of cockpit displays was designed to be three levels (High, medium, and low) by combining four design variables (number of stimuli, number of colors, number of icons, and variance of divisions) affecting visual complexity. A threat scoring equation was developed to determine what information to be decluttered and four decluttering methods (removal, dimming, dotting, and small sizing) were used to figure out how to declutter the information effectively. Human search performance was measured through search time of visual search task in terms of speed and number of hits of signal detection task in terms of accuracy. The main effect of visual complexity levels and the interaction effect were not significant in both search time and number of hits. Meanwhile, the main effect of decluttering methods was significant in search time. Especially, dotting was the most effective decluttering method in terms of speed and accuracy of human perception performance. The results of this study can be applied to information processing of cockpit displays and then contribute to improve pilot situation awareness.
