Abstract
In one aspect, the present disclosure relates to a method for determining a position of a device using a light based positioning system. In some embodiments, the method includes providing a map of positions of a plurality of light sources in a location; receiving an identification code from one or more of the plurality of light sources, wherein the identification code identifies the light source; matching the identification code to a light source on the map; and determining the position of the device by setting the position of the device to the position of the light source on the map. In some embodiments, the method includes receiving identification codes from a plurality of light sources; matching the identification codes to a plurality of light sources on the map; and determining the position of the device based on the location of the plurality of light sources on the map.
