Paper Abstract
The application of stereopsis (true depth) cuing to advanced heads-down flight display concepts
offers potential gains in pilot situation awareness and improved task performance, but little attention has
been focused on a fundamental issue involving their use. The goal of this research was to determine
whether or not the short-term use of heads-down stereoscopic displays in flight applications would
degrade the real-world depth perception of pilots using such displays.
Stereoacuity tests are traditionally used to measure the real-world depth perception of a subject.
This study used such a test as part of the experimental protocol. Eight transport pilots flew repeated
simulated landing approaches using both non-stereo and stereo 3-D heads-down pathway-in-the-sky
displays. At the decision height of each approach, the pilots transitioned to a stereoacuity test using real
objects rather than a two-dimensional target test apparatus.
Statistical analysis of stereoacuity measures (averaged over pilots and replicates), comparing a
control condition of no-exposure to any electronic flight display with the transition data from non-stereo
and stereopsis displays, revealed no significant differences for any of the conditions. Clearly,
transitioning from short-term exposure to a heads-down stereopsis display has no more effect on realworld
depth perception (based on stereoacuity) than transitioning from a non-stereo display. However,
depth perception effects based on size and distance judgements, and long-term exposure remain issues to
be investigated.
