Thank you Masrouri for your very kind words.
In relation to VR in the laboratory, I don't see a lot of educational merit. Geotechnical laboratories are usually, relatively sterile (i.e. uninteresting) environments, where not a lot is happening, and generally at a very slow pace. For all of the effort required to develop a VR simulation of the lab, I think a video will capture pretty much everything of value.
On the other hand, if the test equipment is unique or the test is particularly interesting, there may be merit in pursuing the VR option. Perhaps a large centrifuge, with an interesting package and test setup, might be worthwhile. I'm sure that there are others, but the standard geotechnical laboratory is pretty uninspiring in real life, let alone in VR! (Sorry to all the experimentalists who are like 'pigs in mud' in the lab.)
