    Hi Kevin,

    Each LED lightbulb is blinking really fast – essentially sending out a “Morse Code”. The code for every light is unique. We can pick up these signals using the existing cameras on any smartphone. A database stores the location of each light, along with its corresponding identifier. So when a mobile device moves underneath a light, we pick up the ID, look up its position, and then infer the position of the mobile device. More lights leads to more accuracy through triangulation.
