Abstract:
We developed a novel projector that can embed human imperceptible metadata into the projected image. Human eyes can only perceive the projected images, but high-speed sensors can detect the hidden information from each pixel. We named the system as Pixel-level Visible Light Communication (PVLC) Projector because our method applied the concept of visible light communication to the 2-D array of independent pixels; the metadata are encoded as high-speed flickers (ON/OFF patterns up to 8kHz) on each pixel. Our method can be also regarded as a variant of Display-Based Computing [Sugimoto et al. ], because displayed images are used for controlling devices with sensors. We will demonstrate several intuitive interactions with the projected images.
