Natural versus haploscopic stereopsis.
Natural stereopsis is better with a large interpupillary distance (IPD). With haploscopic devices, depth perception is better with a small IPD. This apparently unknown fact has been trigonometrically calculated and experimentally shown by enlarging and diminishing the IPD in 20 subjects.
