Abstract
Methods and systems are described for sampling an LCom message and accurately decoding the entire LCom message using a light receiver (e.g., digital camera) of a typical mobile computing device, such as a smartphone, tablet, or other mobile computing device. In one embodiment, a curvature method is disclosed to determine LCom signal bit values from a curvature value of a running average calculation of light sensor data. In another embodiment, a signal reconstruction method is disclosed to determine LCom signal bit values from a comparison of modeled data buffers to light sensor data.
