It's thought 2.5 billion people could benefit from technology first developed in the 1200s. At Lockheed Martin, for example, it used to take a technician two painstaking days to measure 309 locations for certain fasteners on a particular curved panel. But according to Shelley Peterson, the aerospace company's head of emerging technologies, the same job now takes little more than two hours. What changed? The technician started wearing glasses. But not just any old glasses: specifically, the Microsoft Hololens. It looks like a bulky set of safety goggles. And it layers digital information over the real world. In this case, it scans the curved panel, makes its calculations, and shows the technician exactly where each fastener should go. Productivity experts are gushing about the potential benefits of augmented-reality devices such as the Hololens and Google Glass. When Google first demonstrated its smart glasses in 2012, their prospects seemed quite different. They were seen as a … [Read more...] about Why do billions of people still not have glasses?
