Special Issue Image Technology of Next Generation. Measurement of Accommodation Responses to a Stereoscopic TV Program.

Abstract

The accommodative responses of subjects viewing a binocular stereoscopic TV program were measured with TDO III (Three-Dimensional Optometer III). The program was produced with two Hi-Vision cameras and VTR's and converted into NTSC format. A field sequential stereoscopic display with a liquid crystal shutter was used to present the program to four emmetropic subjects. It was found that scenes in 3-D presentation with sudden changes in perceived distance of objects and ones containing objects appearing nearer that the screen cause larger accomodative responses than scens in normal 2-D TV presentation.
