Up or Down. A Comparison of Helmet Mounted Display and Hand Held Display Tasks With High Clutter Imagery

摘要

The trade-offs between the costs of increasing clutter by overlaying complex information onto the forward field of view using a helmet-mounted display (HMD) versus the cost of scanning when presenting this information on a hand-held display were examined. Eight National Guard personnel were asked to detect, identify, and give azimuth information for targets hidden in terrain presented in a simulated far domain environment while performing a monitoring task in the near domain using either a HMD or hand-held display. The results revealed that the costs of clutter outweighed the cost of scanning as the amount of information that needed to be inspected increased. The presentation of cueing which guided attention to a large region around the target facilitated detection without imposing the costs of attentional tunneling.
