Pagination or Media Count:
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.
