Bilateral Motion Display: Multiple Visual Perception Depending on Motions

Summary

We proposed a novel projection method that provides completely different visual perception to multiple observers simultaneously using afterimage effects for specific motion. Initially, the projected patterns do not reveal any information; however, when seen by a user moving his or her gaze in a certain direction and speed, they are spatially integrated and appear as 2D afterimages. Our system only requires a high-speed projector to produce user-oriented perception, which expands the range of display expression, and has various applications such as in road signs.
