Color Display on Moving Object Trajectories Using High-Speed Projection

We propose a method to display target colors along the trajectories of moving objects using high-speed projection. This is achieved by leveraging the selective disruption of the afterimage effect, ensuring the target color appears prominently along motion trajectories. In our method, a high-speed projector is used to display multiple frames, consisting of target color frames and a single complementary color frame. This ensures that the target color appears prominently along the motion trajectories of the objects, where the afterimage effect is selectively disrupted, while maintaining color perception when the objects stop. This method enables novel interactions by dynamically adapting visual effects to the motion of objects.
