Experimental Evaluation of Wearable LED Strip for Outdoor Optical Camera Communications Systems

In this paper, we experimentally demonstrate an outdoor optical camera communications (OCC) system utilizing a wearable light-emitting diode (LED) as the transmitter. We explore the practicality of employing commercial devices, such as an LED strip and a smartphone, in OCC links for simultaneous monitoring and communication purposes. In particular, a strip of red-green-blue (RGB) LEDs is modulated to transmit data for user identification via visible light. Each color (red, green, blue and yellow) serves as an indicator of the user's status. Our system exhibits potential applications in high-risk environments where monitoring the physical well-being of individuals is crucial.
