Effects Of Long-Term Viewing Of VISIDEP tm 3-D Television
A.Porter McLaurin, Edwin R. Jones · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1988
A comparison was made between viewing normal television and VISIDEPTM television which produces three-dimensional images by the method of alternating images. Two separate groups of fifteen university students reviewed fifty minute unrelieved exposure to television; one group watched standard television and the other watched VISIDEP. Both groups were surveyed regarding questions of eye strain, fatigue, headache, or other discomforts, as well as questions of apparent depth and image quality. One week later the participants were all shown the VISIDEP television and surveyed in the same manner as before. In addition, they were given a chance to make a direct side-by-side comparison and evaluate the images. Analysis of the viewer responses shows that in relation to viewer comfort, VISIDEP television is as acceptable to viewers as normal television, for it introduces no additional problems. However, the VISIDEP images were clearly superior in there ability to invoke an enhanced perception of depth.
