Improvement of Absolute Distance Estimation Under Water: Use of Monocular Motion Parallax

Abstract

The possible value of monocular motion parallax for improving distance perception under water was investigated. Submerged subjects either kept their heads stationary or rotated their heads about a vertical axis while judging the distance of objects placed 4-15 feet away. Before and after training with feedback to increase judgment accuracy, head movement was related to performance.
