Information processing in real and in stereoscopic environments
(Mensch und Computer 2019 - Tagungsband, 2019) Huckauf, Anke; Eberhardt, Lisa
It is widely acknowledged that the accommodation-vergence-conflict contributes a lot to strain and stress happening in stereoscopic vision. Astonishingly little is known, however, regarding the cognitive consequences. A set-up is developed and introduced which enables the quantification of recognition performance for objects which are viewed out of focus. Experiment 1 showed that in stereoscopic environments, recognition performance for objects behind fixation was in mean twice as good as in real environments. In real environments, recognition of objects presented behind fixation was even worse than in the upper visual field (Exp. 2). Although retinal disparity seems to contribute to this low recognition performance, Experiment 3 showed that in real environments, even without disparate images, processing of objects in depth is rather limited. The data provide a first estimate on how much defocus blur affects cognitive processing in real environments and hence, how much cognitive effort is required in stereoscopic scenes to enable comparable information processing in virtual and in real surrounds.
