Abstract:

Forty-eight individuals were screened for their visual acuity, stereopsis, phorias and color perception. After brief training, their target acquisition performance on a Sonne SC-2 display, of 13000 scale reconnaissance imagery in near-real-time, was measured. The effects of image chromaticity and display stereoscopy were investigated. Stereoscopic skill in the Sonne viewer was measured with achromatic and chromatic transparencies of regular and irregular terrain versions of the Critical Limen Stereo Test CLST, displayed statically and dynamically. Observer performance was correlated across tests. Large individual differences in stereoscopic skill with chromatic and achromatic imagery were found. Chromostereopsis appeared to be a factor contributing to these differences and its measurement was necessary in maximizing predictions with chromatic imagery. Modified author abstract
