The factories of the future have significant demands to meet – including the ability to adapt to production processes quickly and function within tight spaces that come at a high operating cost. Mixed reality can provide efficient support for factory planning in exactly this kind of scenario. Through their HoloLayouts software, researchers at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA have developed an application in which multiple people can collaborate interactively on creating factory layouts that use space efficiently. The factory planning process can be experienced in a virtual environment, with changes made live and in real time.
