ECHO is a new advertising medium which uses the persistence of vision (PoV) effect to generate a fleeting but striking image in the eye of the viewer, from a thin, vertical line of light.There are or no screens or Apps. This is augmented reality for the naked eye.

How does ECHO work? The ECHO system consists of a single thin, vertical reflector, measuring no more than 200mm wide, and a proprietary high-power, high-speed projection system, fixed directly below or above the reflector. ECHO is a Persistence of Vision (PoV) display technology. It works by breaking images down into vertical lines of pixel data and imprinting these lines of data on the viewer's eye. The image exists only in the viewer’s eye and not in reality.
