The issue focused on software applications such as browsers and GPS devices that depend on sensors for measuring motion. While cameras may give users more accurate directions to get home or running errands, sensors need precise distances from objects in order to produce useful results. In 2012, IBM launched its Watson digital assistant software with one goal: finding algorithms that could compute things like distance between cars and bicycles and computing these distances using smartphones. The machine learning platform allowed computers to generate detailed maps of roads based on computer simulations of driving behavior. IBM
