| 摘要： | Two experimental paradigms are examined to establish and model the role of clutter in visual search of aviation displays. The first paradigm involves searching for target aircraft within a cockpit display of traffic information. Clutter imposed by map overlay produces noteworthy costs. Clutter imposed by adding more aircraft imposed less consistent costs. The benefits of the clutter-mitigating solution of airplane highlighting are demonstrated. Only partial support is provided for the most straightforward model of clutter costs, the serial self terminating search model. The second paradigm is a more complex flight task in which the costs of a cluttered synthetic vision system (SVS) display in which traffic and terrain are overlaid, are contrasted with the scanning costs of a more spatially separated SVS display suite. Flight path tracking is equally preserved with both types of display design, and the two forms of costs trade off against each other regarding traffic and terrain awareness. Hence these results are consistent with a weighting model of display formatting that posits equal weights for the two costs. |
