By dividing the world into 3m x 3m squares, each with a unique 3-word address, what3words enables the most precise reference to any location around the globe. In contrast to GPS coordinates, 3-word addresses are easy to remember and, more importantly, they are designed for explicit and error-free voice input in more than 20 languages. Currently used by various businesses, governments, and individuals, this technology is now integrating with the automotive navigation system included in the all-new Mercedes-Benz User Experience (MBUX), featured in the new A-Class. At our Nuance Auto Forums in Detroit and Europe, attendees had the opportunity to experience the 3-word address system and to hear the what3word story and vision presented by Gigi Etienne, what3words Partnerships Manager, and Ashley Cashion, Head of Automotive and Mobility at what3words, personally. For those who could not attend, I had the good fortune to talk to these innovators about what3words and their vision on voice input in vehicles. What was the motivation for developing the 3-words address system?
