The effect of videoconferencing on the depth perception of observers

Wootton, Richard, Collins, Michael J., Loughridge, James S., & Loane, Maria (2001) The effect of videoconferencing on the depth perception of observers. Journal of Telemedicine and Telecare, 7(2), pp. 103-107.


The ability of the human eye to perceive depth was measured using a specially designed instrument. Visual acuity and both monocular and binocular stereo-acuity were measured when viewing the instrument directly and via a videoconferencing link. Ten subjects with an average age of 32.5 years (range 24-50) took part in the study. The group mean visual acuity using both eyes under normal test conditions was -0.04 logMAR (Snellen 6/5) compared with 0.18 logMAR (Snellen 6/10) for the video-link. The mean stereoacuity using both eyes was 37" (SD 18") under normal test conditions. When a videoconferencing link was used, the mean stereoacuity fell to 1218" (SD 1203") using one eye and to 1651" (SD 1419") using both eyes. The ability to perceive depth remotely via a video-link was significantly decreased compared with normal test conditions.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
