This article reviews the technique of verbal protocol analysis and gives a profile of its use within software engineering research over the last two decades. An overview is given of the procedures used in verbal protocol analysis, and commonly-found difficulties in the application of the technique by researchers are described. The article reports on(More)
Spacecraft exploration of asteroids presents autonomous-navigation challenges that can be aided by virtual models to test and develop guidance and hazard-avoidance systems. Researchers have extended and applied graphics techniques to create high-resolution asteroid models to simulate cameras and other spacecraft sensors approaching and descending toward(More)
