Abstract

We have been studying aerial imaging for aerial digital signage. Because the aerial signs have no physical hardware at the image positions, we can walk through the signs. Thus, these signs can be placed right in front of a walker’s face. Signs for kids can be located below 1 m height or so. Advertisement at such lower heights pioneers a new world for digital signage. This system can show information in front of people.
