Product Description
This is a ARMY RESEARCH LAB ABERDEEN PROVING GROUND MD report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A708204. The abstract provided by the Pentagon follows: The effect of indirect vision systems on target detection and recognition is of interest to designers of future combat vehicles. In a field study, eight participants detected and identified pop-up' targets on an outdoor experimental facility from a stationary and a moving vehicle while using a head- mounted display (HMD) and direct viewing as a control, with and without sound localization. A head-slaved camera mounted on top of the vehicle provided the image to the HMD. With sound localization provided by localized auditory cueing, the computer-controlled audio tones (intermittent at a 0.5-second interval) appeared to originate from the location of the target. The results are that more targets were detected with direct viewing than with the HMD and from the stationary position than the moving vehicle. Although more targets were detected with direct viewing from the stationary vehicle without cueing, sound localization improved target detection in all other treatments. Similar comments apply to identification from the stationary position; however, fewer targets were identified from the moving vehicle with sound localization than without. The advantages of auditory cueing for target detection may have been limited by the choice of an intermittent tone for sound localization and the restricted search sector used in the experiment. Ratings of task attention loading show that increased attention was needed for the detection task with sound localization, especially with the HMD. This is also true for the identification task.
