An Experimental Evaluation of the Cueing Procedures Used with the Pilot's Line-of-Sight Reticle
Abstract
Three experiments were conducted to evaluate the cueing procedure for the copilot-gunner's (CPG) line-of-sight (LOS) symbol in the AH-64A pilot night vision system. The location of the CPG, or Cued, LOS is indicated by dots positioned on imaginary axes extending from the arms (0 deg, 90 deg, 180 deg, 270 deg) of the pilot's LOS reticle. The procedure uses either one- two-dot cues to indicate one of eight search areas for locating the CPG LOS. The cueing dots also flash when the pilot must boresight the integrated helmet and display sight subsystem (IHADSS). The three experiments used a selective visual attention paradigm. Experiment 1 evaluated the effects of the number of cueing elements and the presentation duration on the accurate perception of the cues. Experiment 2 compared the effectiveness of the one-and two-dot cues in locating a fixed target. Experiment 2 also evaluated the effects of presentation duration and practice on target identification accuracy. Experiment 3 evaluated the effect of the secondary meaning (boresight required) on the accuracy of target identification under the dot, duration, and practice conditions.
