Abstract
A lighting fixture having a light source, a light sensor, a communication interface, and circuitry is described. In addition to controlling the light source, the circuitry is adapted to monitor for a light signal provided from a handheld device via the light sensor; upon receiving the light signal, measure a signal level associated with the light signal; and effect transmission of the signal level to the handheld device via the communication interface. In one embodiment, the circuitry is further configured to receive an instruction to monitor for the light signal from the handheld device via the communication interface such that the circuitry begins monitoring for the light signal upon receiving the instruction.
