This document discusses using augmented reality (AR) to address wiring challenges in electrical cabinets for submarines. Electric Boat has been building submarines for over 115 years and uses virtual reality for design reviews. They are now developing AR applications for manufacturing, including a project using a Google Project Tango tablet to display 3D wiring diagrams overlaid on cabinets in real-time. This aims to reduce the time spent on wiring connections and simplify transferring designs to physical installations. The presentation provides details on the hardware, software, data access, and potential for other AR manufacturing and shipboard applications.
