Abstract [en]

Our work is motivated by three considerations. First, relative height is a key factor in aviation safety, not least from the pilot´s perspective. Second, in a series of experiments on 3D air-traffic displays we have shown the benefits of 3D presentation. In the experiment here we evaluate the utility of relative height in a 3D display. Third, our task is an example of a focused attention task. While there are findings suggesting that 3D displays are not suitable at all for focused tasks, our hypothesis was that this suitability may be dependent on the cues in the display design. To address these three points, three different cue alternatives were investigated in scenarios with own-ship and targets on a 3D pictorial air traffic display. We found that the addition of more elaborated cues (depth cues and height cues) significantly improved pilots´assessments of relative height. This means that more nuanced design guidelines coud be used.
