Coded LED Flicker Information Communication

Abstract

The technology involves providing illumination via an illumination module, which is perceivable by a person when the illumination module is operating in a first mode. The technology also involves the illumination module emitting a coded pattern when operating in a second mode. This can be done concurrently so that the person cannot perceive the coded pattern. This can involve coordinating a light emitting diode (LED) on/off frequency of the illumination module, along with an image sensor capture rate and exposure time. The coded pattern may be used to complement the information displayed to the person, aid in autonomous operation of a vehicle, identify environmental or other conditions to a computing device, or provide other technical benefits.
