Las imagenes de los tours estereoscopicos tambien eran reagrupadas en colecciones mucho mas extensas que promovian viajes alrededor del mundo a traves del telebinocular (Holmes 1936), en el que se organizaban las imagenes por indices geograficos, agricultura, horticultura, etnias, culturas, arquitectura o historia, entre otras categorias, proponiendo diversas organizaciones de las mismas imagenes.

The Keystone Ophthalmic Telebinocular was used to ensure that potential subjects would be able to read the tasks presented in the experiment.
Participants underwent visual screening and were required to have a minimum Snellen acuity of 20/30 in each eye (either corrected or uncorrected) and a minimum stereoacuity of 145 of arc, as measured by a Multi-Stereo Test in a Keystone telebinocular.
Los optometras evaluarian a los alumnos mediante el telebinocular "Keystone".
Because ability to drive was not accurately predicted by diagnosis, pathology, loss of brain mass, or by neuropsychological tests alone, they developed and investigated the CBDI, which consists of (a) a battery of computerized and paper-and-pencil neuropsychological tests (many related to visual processing); (b) visual screening using the Keystone Driver Vision Telebinocular, which is the machine used in many state drivers' licensing offices; (c) a reaction time test focused on braking ability; and (d) an examination of visual fields.
The minimum requirements to participate in the study were as follows: normal vision as verified by a Keystone Opthalmic Telebinocular, hearing thresholds below 25 dB hearing level in octave bands from 125 Hz to 8 kHz, and a minimum typing speed of 20 wpm.
The 12 volunteer participants (4 women and 8 men; mean age = 27.4 years) all had normal or corrected-to-normal visual acuity and stereo vision of at least 103 arc seconds of relative displacement as tested by an Ophthalmic Telebinocular (Keystone View).
