Center node: "die zukunft sehen die chancen und herausforderungen der erweiterten und virtuellen realitat fur industrielle anwendungen"
  Abstract: Digitalization offers chances as well as risks for industrial companies. This article describes how the area of Mixed Reality, with its manifestations Augmented and Virtual Reality, can support industrial applications in the age of digitalization. Starting from a historical perspective on Augmented and Virtual Reality, this article surveys recent developments in the domain of Mixed Reality, relevant for industrial use cases. #R##N#--- #R##N#Die Digitalisierung bietet f\"ur Industrieunternehmen neue Chancen, stellt diese jedoch auch vor Herausforderungen. Dieser Artikel beleuchtet wie das Gebiet der vermischten Realit\"at mit seinen Auspr\"agungen der erweiterten Realit\"at und der virtuellen Realit\"at f\"ur industriellen Anwendungen im Zeitalter der Digitalisierung Vorteile schaffen kann. Ausgehend von einer historischen Betrachtung, werden aktuelle Entwicklungen auf dem Gebiet der erweiterten und virtuellen Realit\"at diskutiert.
