An analysis of visual perception related to the
underwater environment is presented, followed by a
discussion of 3-dimensional space perception, and the
absolute and relative cues employed by the operator
during task performance. Using a category 1 task,
experiment 1 employed highly practiced subjects to reduce
the effects of learning. Mono and stereo TV performance
was measured under three levels of visibility degradation
(simulated by contrast reduction). As predicted, stereo
was superior to mono under all conditions tested.
Performance using both mono and stereo displays were both
affected by degraded visibility. Experiment 2 was
conducted with naive subjects using an experimental
design which enabled an assessment of the degree of
learning under operator testing conditions. We
hypothesized that the category 1 task would show
significantly less advantage for stereo, but that the
effects of degraded visibility would continue to occur.
The results are consistent with our interpretation. In
experiment 3, the more visually complex category 2 task
was employed. The design of the experiment was similar to
experiment 2 so that evidence for learning could be
assessed under these different conditions. Predictions
concerning the degree of performance advantage for stereo
vs mono displays were supported. This advantage was
observed to increase with decreasing visibility, a
finding which is consistent with our earlier predictions.
