Perceptual motion blur was studied using imagery presented on an LCoS projector equipped with a mechanical shutter to reduce pixel hold-time. Perceptual measures of image blur were obtained with a simple test stimulus, as well as imagery similar to that used in Air Force flight simulation and training. Measured pixel hold-time was found to accurately predict perceived blur.

Perceptual motion blur was studied in imagery presented on an LCD projector equipped with a mechanical shutter to reduce pixel hold‐time. Perceptual measures of image blur were obtained with both a simple test stimulus, as well as real‐world imagery. Both were found to correlate well with the measured pixel hold‐time.

We assessed effects of flight‐simulator spatial resolution and antialiasing on aircraft‐roll detection range. We found that detection range increased with resolution and antialiasing. The antialiasing effect was greater for the lower resolution. These effects held over three levels of aircraft‐roll magnitude (task difficulty).

This project evaluated the effectiveness gained by redesigning a user interface based on the knowledge structure of domain experts. Scenario-based simulation enables realistic training in synthetic environments. As the instructor remains essential to facilitating effective scenario-based training, their user interface should be efficient. Previous research modeled knowledge structures used to redesign a menu within a scenario generation interface. The current research evaluated the redesigned menu based on the ascertained knowledge structures. To evaluate the redesigned menu, participants were timed as they selected target items in the original and redesigned menus. Results indicated that experienced users selected items in the redesigned menu significantly faster, and preferred the redesigned menu to the original. Thus, this result demonstrates tangible benefits to organizing menus according to expert knowledge, even when users are familiar with a menu structure. Using methods that follow the general principles presented here will enable designers to uncover expert knowledge and efficiently configure user interfaces, thereby improving training effectiveness.
