摘要：A 3D stereo image makes a more powerful and realistic impression than a 2D image. We want to clarify the optimal projection conditions for educational facilities and amusement arcades that use 3D stereo images. First, we clarified the degree of impression due to screen for 2D and 3D stereo images. The impressions of 3D stereo images became more powerful and realistic than those of 2D images as the screen size was widened. We statistically examined the opinions of viewers of 2D and 3D stereo images, which were obtained from questionnaires. Visual fatigue sometimes appeared after they watched 3D stereo images, specially when a projection method using two projectors (one for the right-eye and the other for the left-eye) was used. This fatigue appears to be partially related to the projection-size difference. Visual fatigue became more serious when the difference extended beyond 1% of the original size. Using these results, we designed an assembly rack for two projectors (3D stereo projectors) to keep the size difference below 1%.
