OBJECTIVE A novel model of measuring clutter in complex geospatial displays was compared with human ratings of subjective clutter as a measure of convergent validity. The new model is called the color-clustering clutter (C3) model. BACKGROUND Clutter is a known problem in displays of complex data and has been shown to affect target search performance.(More)
Set size and crowding affect search efficiency by limiting attention for recognition and attention against competition; however, these factors can be difficult to quantify in complex search tasks. The current experiments use a quantitative measure of the amount and variability of visual information (i.e., clutter) in highly complex stimuli (i.e., digital(More)
A critical issue in military aviation is the pilot's ability to transition between primarily internal (head-down, instrument-driven) and external (head-up, out of the cockpit) guidance. Experimental cockpit displays were designed and tested for how well they might support this transition phase for military pilots performing time-critical air-to-ground(More)
