Abstract
A system includes one or more optical emitters, a transceiver, and a body mountable device. The optical emitters emit light and are configured to be used in luminaires. The transceiver is coupled to receive input data from a data network and coupled to selectively modulate the optical emitters to transmit the optical data. Selectively modulating the optical emitters is in response to the input data. The body mountable device includes a photodetector coupled to receive the optical data and processing circuitry configured to initiate an action in response to receiving the optical data from the photodetector.
