A series of four experiments was conducted to investigate the independent and interactive effects of three video system parameters on the scaling of depth intervals viewed through stereoscopic stereo combat display systems. Experiment One investigated the effects of interaxial separation and lens magnification. Experiments Two investigated the effects of camera convergence. Experiments Three and Four partially replicated the video system used in Experiment One under more complex scene conditions. For all experiments, ocular fatigue induced by various combinations of system parameters was also measured. For Experiments One, Two, and Three, stereoscopic imagery produced depth interval estimates which were superior to those found under monoscopic viewing conditions. In addition, increasing camera separation and thereby increasing retinal disparities beyond natural stereo values improved depth interval estimation. Camera convergence exerted a significant effect with convergence in front of the area of interest providing greatest accuracy. Lens mangification was not found to exert a significant influence on depth interval estimation. No evidence of ocular fatigue was found under any conditions tested in any of the experiments. Author
