Even in 2017 Bertrandt had an interesting stand on the IAA fair and Totems was responsible for the concept.
Of very much interest was the field HoloLenses.

Bertrandt uses already augmented and virtual reality in various fields of development.
This year there were introduced some operational areas, for example the hololens glasses from Microsoft. The glassses are not opaque so that the developer can see and hear each other.
