In my last year as student at the Higher Institute of Technical Education in Pinkafeld (HTBLuVA Pinkafeld) I and 2 colleagues of me worked on a project to build a 3D driving simulator which could be controlled with a real vehicle. With this project we won the so-called “Technik fürs Leben” price from the Robert Bosch AG. At the bottom you can have a look at the video to see some details.
If you want to have a look at the documentation then follow the link below (it’s in German).
PS: Back then we didn’t use Unity as game engine. We just used a very basic engine called Tribase.
