What3words divides the world into a 3 * 3-meter grid, each square is uniquely identified by three words which creates a global reference system that allows people to identify and navigate between these 3*3 meter squares using 3 words instead of longitude and latitude. Three words are easy to remember and provide an easy and effective way of communicating location to voice-enabled machines. Listen to this interview with one of the co-founders of what3words, Jack Waley-Cohen to learn more about the problems what3words is solving and the thought that goes into building a coordinate system for humans.
