Three-dimensional perception in multi-slit vision for public display

As a low-cost information display in public spaces, we achieved a multi-slit display by the arrangement of LED columns. Multi-slits visually present an image pattern through columns of slits that are arranged several spaces wide. They cannot be perceived image by stop patterns, but they can be perceived by scroll patterns. In this paper, we experimentally show that stereoscopic vision is possible by presenting binocular parallax images that impart the beam direction from slits.
