Abstract

AR (augmented reality) and mobiles are some of the most popular applications for event cameras in the industry. In this demo, we show an AR application using modulated LED markers. The system consists of a frame camera and an event camera that receives AR signals from LEDs (e.g., active markers). As the transmitter, we use a custom-built microcontroller that encodes arbitrary blink patterns. Based on the signals transmitted from LEDs, the frame view overlays AR contents that are decoded via an event camera. Visitors will be able to view and interact with the live demonstrations along with discussions of the system design. https://woven-visionai.github.io/evlc-dataset
