Relative-Motion-Aware Color Presentation with High-Speed Projection

This paper proposes a color image display method where the perceived image changes according to the viewer’s direction of movement relative to the display surface. Conventional motion-responsive displays require camera-based tracking, which poses challenges for privacy and scalability in public spaces. To address this, we propose a display method that leverages the relative motion between the viewer and the display surface without any sensors. The system can present different images for two arbitrary directions of the viewer’s movement. This is achieved by temporally decomposing target images and reintegrating them through high-speed projection, enabling motion-contingent display without external sensors. We describe the mechanism for inducing specific color perception during movement and evaluate image fidelity through experiments. Furthermore, we implement a digital signage application and conduct user studies to discuss its effectiveness. Our approach enables adaptive signage that responds to movement direction without the need for complex tracking systems.
