This study specifically examines wall see-through visualization for drivers at blind corners to prevent crossing collisions. We believe that realizing the desired effect with the simplest visualization is a key to building practical systems, although previous studies mainly targeted rich visualization as if the wall were actually transparent. We compared several visualization levels using qualitative and quantitative measures based on performance of the driver's collision estimation in both central and peripheral vision. Additionally, we analyzed if the difference of the displayed areas and previous knowledge affects differentiation of the visual stimuli. The results revealed that displaying only the direction of the obscured vehicle by a small circle is sufficient for collision estimation, although it was perceived as less informative. Similarly, the difference of the displayed areas did not have a significant effect for the collision estimation performance. We also obtained a result indicating that having previous knowledge on the types of visual stimuli possibly affects the differentiation of them in peripheral vision.
