Lockheed is collaborating with NGRAIN on a trial in which employees wear $700 Epson Moverio BT-200 glasses, transparent glasses with a front-facing camera that uses motion and depth sensors to overlay images onto the technician's working environment. When a glasses-wearing engineer is installing a brake component on the landing gear, they look at the wheel and the chunky glasses show renderings of every bolt and cable, with the part numbers and ordered instructions showing where each part fits. It's like being able to see a hologram of the Legos you need to assemble a project overlaid with the instructions, as opposed to looking down and checking the instruction manual.
