Abstract

Ultralow-latency communication is critical for emerging next-generation applications such as XR, real-time control, and distributed sensing. We present ECO-COMM, an event-camera-based optical communication system for ultra-low-latency device association and lightweight information exchange. By exploiting the asynchronous sensing and microsecond-level temporal resolution of event cameras, ECO-COMM captures high-frequency optical signals without frame-based acquisition delays. We identify and analyze key hardware-induced challenges in event-camera communication, including timestamp inconsistency, readout contention, trailing effects, and the inevitable refractory period, and develop hardware-aware mitigation techniques to address them. Focusing on a single transmitter-receiver optical link, ECO-COMM establishes the feasibility of practical ultra-low-latency event-camera communication using commercially available hardware.A prototype implementation using an eight-LED transmitter and an off-the-shelf event camera achieves device association within 15 microseconds, symbol latency as low as 100 microseconds, and end-to-end latency below 8 milliseconds for 32-byte payloads at 0.1% bit error rate. ECO-COMM establishes a practical and complementary communication paradigm for ultra-low-latency systems where responsiveness and temporal precision are paramount.
